Confusing, isn’t it? Conflicting advice is everywhere, and you’re stuck in the middle. You wonder whether anyone out there even knows what they’re talking about, or whether the experts will ever reach a consensus on anything. You start to wonder whether you’ll need a degree in nutritional biochemistry before you can lose that stubborn abdominal fat. So what’s the deal? Why so much confusion? Why does one expert suggest that high protein is best for everyone, while another expert suggests high carb and yet another expert suggests high fat? Besides, what exactly do high protein, high carb, and high fat really mean? And why are other experts telling us that food choices should be based on our "metabolic type," our "blood type," or our "ancestry"? One expert says to eat like a Neanderthal and another says eat like a Visigoth, or perhaps a Viking. But while searching for nutritional Valhalla, most people just get lost and eat like a Modern American—and end up looking more Sumo than Samurai. These days, we have a cacophony of expertise: lots of confusing noise from the experts drowning out the signal of truth. On the surface, it appears as if today’s nutrition technology is quite advanced. After all, we have at our disposal more nutrition information than ever before. More money is being spent on nutrition research than in any time in history. Every day, impressive strides are being made in the field. Dozens of nutrition experts are rising to prominence. Yet simultaneously we’re witnessing a steadily increasing rate of obesity, an increase in nutrition-related illness (Diabetes, CVD, and Syndrome X), and an increase in nutritionrelated mortality. Part of the problem is that much of the information hasn’t reached the people who need it. Part of the problem is that even when it does reach those people, they often don’t use it. And certainly, the problem is multifactorial—there are probably many more reasons than I can list here. How much more information do we need? But the curious thing is that many people try to solve the problem by seeking out more information. They know it all and still want more. If there’s one thing of which I am absolutely convinced, it’s that a lack of good nutrition information isn’t what prevents us from reaching our goals. We already know everything we need to know. Sometimes the real problem isn’t too little information but too much. All the fundamental principles you need to achieve good health and optimal body composition are out there already, and have been for years. Unfortunately, with 500 experts for every fundamental principle, and very little money to be made from repeating other people’s ideas, experts must continually emphasize the small (and often relatively unimportant) differences between their diet/eating plans and the diet/eating plans of all the other experts out there. In the world of advertising and marketing, this is called "differentiation." By highlighting the small distinctions and dimming out the large similarities between their program and all the others, they’re jostling for your next nutritional dollar. Now, and let me be clear on this, I’m not accusing nutrition experts of quackery. Yes, some programs are utter crap. Those are generally quite easy to pick out and don’t merit discussion here. But most experts do know what they are talking about, can get results, and wholeheartedly believe in what they’re doing. Many of the differences between them 5 are theoretical and not practical, and on the fundamentals they generally agree completely. It’s all good — sorta In fact, many of the mainstream programs out there, if not most of them, will work. To what extent they work, and for how long, varies. As long as a program is internally consistent, follows a few basic nutritional tenets, and as long as you adhere to it consistently, without hesitation, and without mixing principles haphazardly taken from other programs, you’ll get some results. It’s that simple, and that hard (as you can see, results depend as much on psychology as on biochemistry). But if you’re like most people, you’ll first survey all the most often discussed programs before deciding which to follow. And in this appraisal, you’ll get confused, lost, and then do the inevitable. That’s right, you’ll revert back to your old, ineffectual nutrition habits. Instead of parsing out the similarities between all the successful plans out there, the common principles that affect positive, long-term change, you get thrown off the trail by the stench of the steaming piles of detail. The Atkins program works for all patients under the direct care of the Atkins team—as long as patients follow it. The Zone program works for all patients under the direct care of the Sears team —as long as they follow it. The Pritkin Diet works for all patients under the care of the Pritkin team— as long as they follow it. Yet, not all three plans are identical. How then, can they all get impressive improvements in health and body composition? Well, either each team somehow magically draws the specific patient subpopulations most in need of their plan (doubtful) or each system possesses some basic fundamental principles that are more important than the ratios of protein to carbs to fats. The 7 Habits of Highly Effective Nutritional Programs Here’s my take on it. I call these principles, "The 7 Habits of Highly Effective Nutritional Programs," a shameless and possibly illegal play on Steven Covey’s book, "The 7 Habits of Highly Effective People." (Great book, by the way—you should read it sometime.) These aren’t the newest techniques from the latest cutting-edge plan. Rather, they are simple, time-tested, no nonsense habits that you need to get into when designing a good eating program. 1. Eat every 2-3 hours, no matter what. You should eat between 5-8 meals per day. 2. Eat complete (containing all the essential amino acids), lean protein with each meal. 3. Eat fruits and/or vegetables with each food meal. 4. Ensure that your carbohydrate intake comes from fruits and vegetables. Exception: workout and post-workout drinks and meals. 5. Ensure that 25-35% of your energy intake comes from fat, with your fat intake split equally between saturates (e.g. animal fat), monounsaturates (e.g., olive oil), and polyunsaturates (e.g. flax oil, salmon oil). 6. Drink only non-calorie containing beverages, the best choices being water and green tea. 7. Eat mostly whole foods (except workout and post-workout drinks). So what about calories, or macronutrient ratios, or any number of other things that I’ve covered in other articles? The short answer is that if you aren’t already practicing the abovementioned habits, and by practicing them I mean putting them to use over 90% of the time (i.e., no more than 4 meals out of an average 42 meals per week violate any of those rules), everything else is pretty pointless. Moreover, many people can achieve the health and the body composition they desire using the 7 habits alone. No kidding! In fact, with some of my clients I spend the first few months just supervising their adherence to these 7 rules—an effective but costly way to learn them. 6 Of course, if you have specific needs, or if you’ve reached the 90% threshold, you may need a bit more individualization beyond the 7 habits. If so, give me a shout at [email protected], or search around on this site. Many of these little tricks can be found in my many articles published right here at T-mag. But before looking for them, before assuming you’re ready for individualization; make sure you’ve truly mastered the 7 habits. Then, while keeping the 7 habits as the consistent foundation, tweak away. 1.2 Covering Your Nutritional Acids by John M. Berardi It's Out There But I'll Be Damned If I Can See It While I do my best try to stay abreast of the latest nutrition and supplement research, once in a while I find myself totally ignorant to an important topic or sound body of literature. Take, for example, creatine-monohydrate supplementation. At this year's American College of Sports Medicine annual meeting, I heard about this wonder supplement for the very first time. After asking several naïve questions, my embarrassed friends and colleagues informed me that creatine has been used for years and was perhaps the most popular ergogenic aid ever! In addition, I found out that at least 500 studies have been published, with over 70% of them demonstrating a positive effect. Go figure (scratching head)! Alright, I'm just kidding about not knowing about creatine, but the fact remains; once in a while some important literature eludes my discriminating eye. You can't blame me, though. A search of Medline (PubMed.com), my favorite search engine for literature reviews, narrowed down to all abstracts published in the year 2003 with the keyword "nutrition," generates over 2,300 published papers. Now that's a lot of literature to sort through! I See The Light The latest topic that I've remained fairly ignorant about until very recently is the strong relationship between food selection and the acid-base balance of the body. As many of you know, I lead the campaign against the old adage: "a calorie is a calorie." In fact, I've written an entire article on the topic entitled Lean Eatin'. While my crusade has focused on proper food selections to enhance the thermic effect of feeding as well as the hormonal response to different foodstuffs, I've recently acquired a whole new weapon for my assault. You see, different foods — based on their digestibility, micronutrient composition, protein content, and a number of other factors — can lead to marked fluctuations in the acid-base status of the body. Since many of you are probably wondering what this has got to do with looking good nekid, I encourage you to read on and find out how the acid-base balance of the body is critical to your health, your body composition, and even your exercise performance. Furthermore, find out how a few simple food substitutions and/or a few inexpensive supplement additions can correct your acid-base woes. Before I get down to it however, I've got to give credit where credit is due. I can't assume full responsibility for stumbling across this fascinating line of research. It was actually a fellow researcher and nutrition colleague, Dr. Loren Cordain (of Paleo Diet fame) who pointed me in this direction during a recent "roundtable" we did together. So, if after you've read this article you feel compelled to thank someone for the great information, give him a shout at PaleoDiet.com (and then you can feel free to praise me at JohnBerardi.com). Acid-Base Nutrition Basics When a food is ingested, digested, and absorbed, each component of that food will present itself to the kidneys as either an acidforming compound or a base-forming one. And when the sum total of all the acid producing and the base producing micro and macronutrients is tabulated (at the end of a meal or at the end of a day), we're left with a calculated acid-base load. If the diet provides more acidic components, it will obviously manifest as a net-acid load on the body. And if 7 it provides more basic components, it will obviously manifest as a net-base load on the body. In the past, scientists have looked for various techniques to try to quantify whether a food is acid producing or base producing. One method that was commonly used was ash analysis. Using this technique, a food would be combusted and the ash would be analyzed to determine how much of the food was alkaline and how much was acid. When examining the micronutrients present in many foods we see that: • Acidic anions in food include chloride, phosphorous, sulfates, and other organic acids. • Basic/Alkaline cations in food include sodium, potassium, calcium, and magnesium. The ash analysis technique has its limitations, though. Since simple food/ash analysis doesn't take into account bioavailability of the nutrients in a given food, the acid-base balance of the body after consuming specific foods doesn't often match the acid or base-producing estimate generated from the ash analysis. In other words, the ash analysis ain't all that effective. Recognizing this limitation, Remer and Manz developed food-rating values that they refer to as PRAL (potential renal acid load) and the NAE (net acid excretion). (1) The NAE can be determined directly by measuring the acid and the ammonium appearing in the urine and then subtracting out the measured urinary bicarbonate. This method yields a net acid excretion score based on direct measurements of the urine. This score, however, reflects total acid and base load of a mixed diet and not the acid or base load of the individual foods in the diet. To more accurately predict the acid or base potential of a given food, another technique is needed. Unlike the aforementioned technique, the NAE can be determined indirectly by adding up all the urinary acidic anions from the above method and subtracting out the basic/alkaline cations described above. Since the urinary anion and cation excretion is directly related to food intake, it's possible to approximate net acid or base load from the composition of the food. This net acid or base load is called the PRAL (potential renal acid load). Therefore, in taking into account the composition of the food, the bioavailability of the different micro and macronutrients (especially protein) of the food, the sulfur content of the food, and the obligatory dietindependent organic acid losses, it's then possible to estimate a physiologically meaningful index of the acid or base load based on the food consumed (PRAL). For those of you who don't really care about PRALs and NAEs, here's the one sentence summary of what I'm talking about. In layman's terms, researchers can now analyze a food and based on its components, determine what the true acid or base load on the body will be. If you're still wondering why this is important, read on. Why Acid Is Bad Every cell of the body functions optimally within a certain pH range (pH is a measure of the acidity or alkalinity of the body). In different cells, this optimal range is different, however, the net pH of the body has to remain tightly regulated. One common problem with most industrialized societies is that our diets produce what's called a "low grade chronic metabolic acidosis." In other words, the PRAL of our diets is high and this means that we're chronically in a state of high acidity. While there are a number of disease states that induce severe metabolic acidosis, we're talking a sub-clinical rise in acidity here. Therefore, your doc probably won't notice the problem. But that doesn't mean that you're in the clear. Your cells will recognize the problem. So what's wrong with this low-grade chronic metabolic acidosis? Well, since the body must, at all costs, operate at a stable pH, any dietary acid load has to be neutralized by one of a number of homeostatic base-producing mechanisms. So, although the pH of the body is maintained and your doctor visits turn out fine, many cells of the body will suffer. Here are some of the most severe consequences of 8 your body's attempt to maintain a constant pH in the face of an acidic environment: • Hypercalciuria (high concentrations of calcium in the urine). Since calcium is a strong base and bone contains the body's largest calcium store, metabolic acidosis causes a release in calcium from bone. As a result, osteoclastic (bone degrading) activity increases and osteoblastic (bone building) activity decreases. The net result of these changes is that bone is lost in order to neutralize the acidic environment of the body. The calcium that was stored in the bone is then lost in the urine along with the acid it was mobilized to neutralize. This creates a negative calcium balance (more calcium is lost from the body than is consumed) and bones get weak. (2,3,4,6) • Negative nitrogen balance (high concentrations of nitrogen in urine). Glutamine is responsible for binding hydrogen ions to form ammonium. Since hydrogen ions are acidic, glutamine acts much like calcium to neutralize the body's acidosis. Since skeletal muscle contains the body's largest glutamine store, metabolic acidosis causes muscle breakdown to liberate glutamine from the muscle. The amino acids from this muscle breakdown are then excreted, causing a net loss of muscle protein. (2,7) In addition to bone and muscle loss, other consequences of acidosis include: • Decreased IGF1 activity (4) • GH resistance (4) • Mild hypothyroidism (4) are unfortunate consequences of aging. While it's too early to tell, perhaps some of the bone and muscle loss evident as individuals get older is a result of diet-induced acidosis. This means that employing a few simple acid-base strategies may help slow osteoporosis and sarcopoenia. What's Wrong With Your Diet? Recently, Sebastian and colleagues compared the pre-agricultural diet of our ancestors to the modern North American diet.(8) After evaluating the two diets for what they call NEAP (net endogenous acid production) — essentially the same measure as the PRAL above — a -88mEq/day acid load characterized the pre-agricultural diet while the modern diet was characterized by a +48mEq/day acid load. What this means is that our ancestors evolved eating a diet that was very alkaline/basic and therefore very low acid. However, modern people are eating a diet that is high in acid, and therefore very different from what we evolved to eat. As a result, our modern diet is responsible for what the authors have called a "life-long, low grade pathogenically significant systemic acidosis." How have we gotten so far off track? Well, the shift from net base producing foods to net acid producing foods comes mostly as a result of displacing the high bicarbonate-yielding plants and fruits in the diet with high acid grains. In addition, most of our modern energy dense, nutrient poor selections are also acid forming. Finally, high protein animal foods tend to be acid producing as well. If you're now wondering how your diet stacks up, check out the table I've provided below. This table includes a listing of 114 commonly consumed foods and their PRAL scores. A negative PRAL score indicates the food is basic/alkaline. A positive PRAL score indicates the food is acidic. A score of 0 indicates the food is neutral. • Hypercortisolemia (4,5) Interestingly, low-grade metabolic acidosis seems to worsen with age. Many have speculated that this is due to an age-related decline in kidney function (and acid excretion).

After all, even a high protein diet rich in clean, whole grain carbs will produce a net acid load. Since a neutralization of the Western diet without a change in energy intake or macronutrient composition has been shown to improve bone health, to shift nitrogen balance from negative to positive, to reduce blood cortisol concentrations, to increase thyroid hormone production, and to reverse the GH resistance discussed above, it's important that athletes take the appropriate steps to shift their diets away from that low grade chronic metabolic acidosis we discussed earlier. Here are some steps for accomplishing this goal: Food Group and Food PRAL Score Legumes Average 1.2 Green Beans Lentils Peas -3.1 3.5 1.2 Fats and Oils Average Butter Margarine Olive Oil Sunflower Oil 0 0.6 -0.5 0.0 0.0 Beverages Alkali rich average Alkali poor average -1.7 0 Draft Beer Pale Beer Stout Beer Coca-Cola Cocoa Coffee Mineral Water Red Wine Tea White Wine -0.2 0.9 -0.1 0.4 -0.4 -1.4 -1.8 -2.4 -0.3 -1.2 *This table is adapted from the Remer and Manz study discussed above (1) and each PRAL score is based on a 100g portion of food. • Use the chart above to calculate a PRAL score for each meal. To do this, you simply record the amount (in grams) of each food you eat in a meal. Then, multiply the PRAL score listed by your food amount. For example, if you've eaten 250g of lean meat (8 oz or about 1/2 lb), your PRAL score for the meat will be 7.8 (score for 100g) multiplied by 2.5 (for the 250g serving), or 19.5. If you've also eaten 250g of potato (8 oz or 1/2lb), your PRAL score for the potato is -4 (score for 100g) multiplied by 2.5 (for the 250g serving) or -10. In addition, if you've eaten 100g of spinach, the PRAL score for the spinach is -14. If you tally up the total score of this meal, the net PRAL is 19.5 (meat), -10 (potato), -14 (spinach), or -4.5. This means a meal containing 8 oz of lean meat; 8 oz of potato, and 3.5 oz of spinach produces a PRAL of -4.5. In other words, the meal produces a net alkalinity. That's what we're looking for. • After calculating the base or acid potential of the meal, add more vegetables regardless of the final tally. Everyone can always benefit from more vegetables in the diet. Many bone specialists are now recognizing that the most effective way to improve bone health is to eat lots of fruits and vegetables. (3) 11 • If you're eating a big meal that's going to be a net acid producer and don't want to add more basic foods, consider adding a small amount of glutamine to this meal. Exogenous glutamine supplementation has been shown to neutralize acidosis. (7) • A cheaper alternative to glutamine supplementation is either sodium or potassium bicarbonate supplementation. You can add sodium bicarbonate (in the form of baking soda) to your beverages including your protein shakes, which probably are a bit on the acidic side (see milk above). A small 2-5g dose of baking soda would be sufficient to neutralize the shake. An alternative to baking soda is alka-seltzer. • Adding sodium to foods can increase the base potential and reduce the acidity of the meal. A Few Additional Protein Notes Many doctors, dietitians, and sports nutritionists have come down on animal protein for several reasons including its effect on renal acid load. While it's true that animal protein (especially animal flesh) does produce a high PRAL, I find it interesting that the same "experts" espouse high grain diets. As you can see from the charts above, whole grains are also very acid forming. Another interesting fact is that while a high protein diet is acid forming, the high protein diet also seems to counteract some of its own acid loading potential. (9) In other words, while protein produces an acid load, it also increases the body's capacity for excreting those acids. None of the other acid producing foods are as effective as protein in doing so. Besides, just like with the other acid-forming foods, all you have to do is consume enough basic foods and supplements to neutralize the acidity. Conclusions Just because very few individuals in the sports-nutrition world are talking about acidbase balance doesn't mean that it's not important. Employing a few simple strategies to neutralize your high-acid diet may mean the difference between chronic low-grade acidosis — and the associated muscle wasting, bone loss, and altered hormonal profile — and a healthy, alkaline diet. 1.3 Defeating Dietary Displacement Part 1 by John M. Berardi Coffee Anyone? I’ve got this buddy who seems to love going out for coffee with members of the opposite sex. Wait, let me clarify. He loves going out for coffee with exceptionally good-looking members of the opposite sex. Almost every time I call this guy during afternoon hours, he’s on one of these coffee dates with one of his little hottie "coffee friends." Now, I know what you’re thinking. "Going out for coffee" must be some clever euphemism we use for sex. After all, what kind of high Testosterone weight lifter sits around all day drinking coffee when he could be doing the "wild thing" with said hotties? But alas, rather than slowing his testicular production of the male hormone, my buddy assures me these "coffee dates" are components critical to his style of dating—and his success. Intrigued, I decided to give the coffee date a try. The Origin of Obesity? So there I am, sitting in my favorite coffee shop across from my "coffee friend." Things are off to a good start. We’re laughing, she’s playing with her hair, and she’s reaching across the table touching my arm when I make a particularly witty comment. Note to self: "I’m in there!" I order a green tea, a pitcher of water, and two chicken breast sandwiches (no bread, no mayonnaise, double the vegetables, please). Because it’s my "free" or "cheat" day, I preorder dessert— a slice of warm apple pie. With mouth agape and that "where do you put it all?" look on her face, my coffee friend orders a chocolate brownie and a double latté. Then it happens: she starts asking the nutrition questions. 12 Internally, I groan. Only fifteen minutes into the meeting and we’re talking about the subject I usually like to steer clear of when I’m off the clock, especially with new people. It’s better to slowly wean them onto my diet ideas than to launch right into it during the first meeting. Damn my buddy and his "coffee dates"! But then, during the ensuing conversation, which wasn’t as bad as I'd initially predicted, something else happened. In talking nutrition with my coffee friend, I realized that during this meal I was getting a very clear insight into the very "obesification" of North America. Now, this girl is definitely not obese. She’s young, thin, and a real hottie. But in ten or twenty years, she will be obese if she continues to regularly dine on rich chocolate brownies and frappaccinos for lunch, bagels and coffee for breakfast (her admitted breakfast of choice), soda throughout the day, and leftover casserole for dinner. Of course, obesity isn’t imminent in her case. She’s a young, intelligent, and reasonably disciplined woman, and she’ll probably be able to restrain her eating habits (i.e., curtail her total daily energy intake) enough to stave off full-blown obesity. But the fact is, simply moderating ones portions isn't enough to achieve optimal body composition and health. Dietary Displacing: The "All-Treat" Diet At this point some of you might be thinking, "Hold on just a minute, JB, didn’t you order the apple pie? Why are you railing against her when you’re just as guilty of ordering junk as she is?" Sorry, that sort of thinking is flawed. There's a big difference between a healthy diet to which treats are occasionally added and an all-treat diet. In the former, less healthy foods are consumed rarely and in addition to healthy foods. In the latter, less healthy or unhealthy foods are consumed often and instead of healthy foods. This is called food displacement and must be avoided if optimal body composition and health are your goals. Sure, I did indulge in a slice of sugar-laden junk food, this being one of the two "treats" I ate that week. But looking only at the junk food that we ate presents a woefully incomplete part of the picture. The presence of bad food in both of our diets is much less important than the absence of good food in hers. To elaborate: I ate a small amount of junk food in addition to my antioxidant rich, protein filled, nutrient dense meal, which was just one of seven such meals I ate that day—and that was one of seven such days that week! She ate some junk. Period. She started her day with junk, ate a lunch of junk, and filled the rest of the day with junk as well. I got all the antioxidants, micronutrients, and protein I needed, while she spent the entire day eating the nutritional equivalent of a cardboard box. Based on our activity levels and basal metabolic needs, we both probably met our energy needs for the day (in terms of total energy ingested vs. total energy expended), but I actually got some nutrition that day. She just got calories, and her calories came from what we call "displacing foods." You see, the bagel, the brownie and latte, the soda, etc. were consumed instead of good healthy choices. So, in essence, their empty calories displaced the good, nutrient dense food she could've otherwise eaten. She consumed nothing but empty calories, calories more likely to be stored as fat than burned, calories that actually degrade health or do nothing to improve it, calories that'll make her hungry and food-obsessed all day, and calories that'll make her tired just an hour or two after consumption. I ate 49 healthy meals plus two treats that week. She had all treats. Big difference, huh? Convenience and Calories: Overfed, Undernourished Know anyone else like this girl? Chances are you know lots of other individuals like her! In the US alone, there are about 129.6 million overweight individuals and probably many more well on their way, just like my coffee friend. These stats beg the question—how did otherwise intelligent people get to be so bad, exchanging good nutrition for empty calories? 13 While an explanation is probably multifactorial, there are a few simple answers that pop into my mind. First, I think that North Americans strive daily for nutritional convenience. Sure, when the typical person goes out for a nice dinner at a restaurant, he or she usually gets a decent meal. But, unlike many Europeans (the French and the Italians come to mind), North Americans select everyday meals for speed and convenience. A nice egg and spinach omelet with oats and pineapple on the side takes some time to prepare and eat. On the contrary, a bagel and coffee can be carried into the car and eaten on the way to work. So in our quest for speed and convenience, we get very little in the way of good nutrition. That’s why we’re overfed and undernourished, and that's how people can eat so much yet still have nutrient deficiencies. Secondly, I think we’ve gotten too calorie conscious. Most people who make poor food selections aren’t stupid. They know if they want to be thin, they can only eat a certain amount of calories per day. If they eat more, they either feel monumentally guilty or, much less often, they head to the gym for marathon cardio sessions designed to exercise those extra calories off. In trying to walk that thin tight rope of energy balance, they realize if they eat good, healthy food (i.e. marinated chicken breast with a spinach salad and a piece of fruit), they’ll be eating a bunch of calories which simply don’t taste as good as the brownies they’re craving. In this sense, the healthy food will displace the tasty junk they often crave. So in an attempt to get the tasty brownie calories, they choose instead to displace the good chicken and spinach calories, kicking them out of the diet. In their minds, "a calorie is a calorie" and therefore if they simply eat a brownie instead of the chicken, they’ll stay just as thin. Thin, in our society, is synonymous with healthy. Little do they realize they’re setting themselves up for losses in lean body mass, an ever slowing metabolic rate, micronutrient deficiencies, and all sorts of nutrition related health problems including diabetes, cardiovascular disease, and syndrome-x (basically insulin resistance). It’s hard to stay lean when the metabolism is dwindling as a result of insufficient protein intake and a low thermic effect of feeding. The metabolic rate takes another plunge because of deficiencies in essential fatty acids, not to mention decreasing muscle mass. It’s also pretty difficult to stay lean if you’ve got diabetes, cardiovascular disease, and/or syndrome-x. To support this notion, all we need to realize is that in the last twenty years the incidence of obesity has doubled, yet our average daily energy intake hasn’t increased much at all! North Americans aren’t getting so darned fat and/or unhealthy simply because of overeating. Often they replace good foods with the super-sized sugars, the trans fats, and the other nasty fast food ingredients. The good foods have the power to negate the effects of these nasty, health-degrading junk foods, but because people become too concerned with energy balance, they simply displace the good stuff. In fact, if people simply ate a high protein, antioxidant and micronutrient rich diet supplemented with junk food, they’d end up leaner and healthier than those who got the same amount of calories (and often even fewer calories) from empty, displacing foods. Cheat Meals People often ask me what I think about cheat meals. Generally, what they want to know is, "Do I really have to eat clean all the time?" The answer is a qualified "yes." You should plan out your diet in advance, choosing only clean foods, and then eat everything on your plan. One or two days a week, if you so desire, you can eat foods that wouldn’t normally be found on your plan in addition to and not instead of the healthy foods. Usually I add such foods at the end of the day, when I’m already stuffed with lean meat, EFAs, fruits and veggies. That tends to limit my ability to indulge. Of course, in strict fat loss phases, these calories should be the first to go. 14 Bottom line: As long as it doesn’t displace the good calories, you can have your cake and eat it too. Chew on that a while and then check back next week for Part II of this article: "Displacing Debates"! 1.4 Defeating Dietary Displacement Part 2 by John M. Berardi Paralysis by Analysis In part one of this article, I presented a few ideas as to why the obesity rate is rapidly increasing in spite of the fact that, on average, our calorie consumption as a society hasn’t increased all that much. In that article, I discussed the idea of a "displacing" food, a food that provides very little nutrition while simultaneously taking the place of the nutritious foods you might have consumed instead. In my opinion, displacing foods are covering our breakfast, lunch, and dinner tables and it’s this shift toward empty calories that's making us unhealthy and obese. In this article, I’d like to discuss another displacement idea. While displacement foods are probably at the root of many of our health and body composition crises, what I call "displacement debates" have also become a real problem. According to my definition, a displacement debate is a debate that, rather than helping people move closer toward healthy nutritional choices, simply acts to confuse and paralyze them. of suggesting that people just do something, these groups continue to bicker about who’s right at the expense of an ever-growing obesity rate. Below I’ve presented six of the interesting displacing debates I’ve heard argued lately. Hopefully by discussing them I can put to rest the idea that these issues are of critical importance to your overall health and body composition. I’d like you to understand that these represent small, fine tuning details that are only relevant to a small percentage of the population, if that. On the whole, these debates do more to confuse and paralyze people than to encourage them to take their health into their own hands. The Top 6 Displacing Debates 1. Fruit is Bad Now? We all know fruit provides fiber, vitamins, minerals, and low glycemic index carbohydrates, so it should be no surprise that many experts recommend eating a few servings of fruit each day. Heck, this notion has even been turned into a clichéd rhyme: "An apple a day keeps the doctor away!" Yet some experts out there (short-sighted experts with a real lack of perspective, I might add) actually suggest that fruit might be bad for us! That’s utter nonsense. For example, the average North American barely knows what a carbohydrate, protein, or fat is, yet when they hear well-respected experts at the ADA recommend high carb diets and the highly (though not universally) respected Atkins group recommend low carb diets, they get so confused and frustrated they ultimately do little or nothing proactive to improve their health. So, imagine you’re someone with a lifetime of eating habits that are less than optimal (for some of you, it might not be so hard to do) and you’re exposed to this debate. What do you do? Well, nine times out of ten, you figure that if there’s a chance fruit is bad for you, you might as well stay away from it — probably better to reach for a Big Mac instead. After all, it does taste better. This argument is an example of a displacing debate: an academic argument that pushes the more important problems out of the public discourse. For the average North American, following either the ADA recommendations or the Atkins recommendations would go a long way toward improving their health. But instead Verdict: Eat the damn fruit. 2. Raw? Organic? Speaking again of fruits (and vegetables), it’s recommended that the average person consume two pieces of fruit and three servings 15 of vegetables per day as a bare minimum. Athletes probably need even more, yet most North Americans (athletes included) consume far less than the standard recommendation of five servings of fruits and vegetables. However, rather than simply recommend more fruit and veggies (no matter how you can get them, for any fruits and vegetables are better than none), experts spend their time fighting about canned fruits and veggies vs. raw fruits and veggies. And then they fight about raw fruits and veggies vs. organic fruits and veggies! Sure, I agree that raw, organic fruits and vegetables are best since they probably have a higher micronutrient count, but let’s face the facts: any fruits and veggies are better than none! So again, imagine you’re someone with a lifetime of bad eating habits and you’re exposed to all this bickering. What do you do? Well, you'll probably avoid the fruits and veggies, wait for the experts to finish dueling it out, and reach for a Snickers bar instead. Verdict: Get sufficient fruits and vegetables in your diet before worrying about whether they’re organic or not. Once you’ve done that, worry on. 3. Raw Milk vs. Regular Milk What about milk? Most T-Nation readers know my stance on moo juice. In my opinion, it’s not necessary, doesn’t always "do the body good," and should be minimized in the diet (although I see no need for total elimination unless you’re lactose intolerant). However, if we could simply get more people to drink milk instead of sugary soda, we’d have less obesity and disease. But instead of focusing on healthy behaviors, experts will bicker on and on about regular milk vs. raw milk. Of course, all this does is serve to draw negative attention to milk and away from the other healthy decisions people could be making. Sure, if it were possible to get raw milk that was guaranteed aseptic, it would be better than processed, pasteurized milk. But faced with the confusion, what do you, the hypothetical sub-optimal eater, do? Well, nine times out of ten, you avoid both kinds of milk and drink another Coca-Cola instead. Verdict: Limit milk, and drink calorie-free beverages like water and green tea instead. 4. Tap Water vs. Bottled Water Speaking of beverage consumption, people are dehydrated because they drink too little water while drinking too many caffeinated, diuretic drinks (coffee, soda, and alcohol). Dehydration leads to all sorts of health problems for the inactive, not to mention the decrements in athletic performance seen in dehydrated athletes. But rather than simply promoting the heck out of water consumption, experts will bicker on and on about tap water vs. bottled water. Sure, good quality bottled water is usually a better choice, but don’t be one of these people who stay away from tap water, forget to pick up their bottled water, and simply remain dehydrated. Verdict: Drink sufficient water first; worry about the source later. (Of course, you may want to avoid drinking out of puddles next to pig farms in Uganda.) Put a water filter on your tap or buy one of those filter jugs you store in your fridge and be done with it. 5. Glass vs. Plastic And how about the bottles the water comes in? That’s right, the glass vs. plastic debate. Just the other day, I was recommending that a group of my athletes pick up some Tupperware so they could whip up all of their meals and shakes in the morning. It’s easy to make a good food choice during the day when you’ve got all your good food with you, pre-cooked, pre-wrapped, and ready to be eaten. After the talk, one of the athletes came up to me and told me he avoids Tupperware altogether because of the potential leeching of xenoestrogens into his food. When I asked what he uses to store his food in, he told me he doesn’t even preplan his meals. He also told me he needed to lose fifteen pounds and 16 that he was overweight because his nutrition sucked! Buddy, I agree that glass containers may be marginally better than plastic, but for the love of God, pick up some plastic if it'll help you plan your meals! And this was a world-class athlete! You can imagine how the average guy fares! Verdict: Plan your meals in advance, storing them in woven baskets if necessary. Buy the best containers you can afford. If you can get the glass versions, great; if not, the generic plastic ones will do just fine. are less than optimal and you’re exposed to all this bickering about lean protein. What do you do? Well, when you’re afraid of the meat you have access to, you shy away from all types of lean meat and reach for another bagel. Bad choice! Verdict: Find the best meat you can by going around to various grocery shops and butchers. Owners of health food stores may also be able to help you locate the best stuff. But don’t be afraid to eat the meat you find in your grocery store — the reports of your impending death are greatly exaggerated. Conclusion 6. Free Range vs. Extremely Limited Range Meat Most weightlifters eat lots of protein and that’s no mistake. I’ve outlined the myriad of benefits associated with a high protein diet in my article, The Protein Prejudice. One of the best ways to get all that protein is by eating a lot of protein and micronutrient-rich lean meat. Protein supplements are okay to supplement your diet, but real food should be your nutritional mainstay and there’s nothing better than good ol’ fashioned meat. Since eating more protein can increase metabolic rate, improve your weight loss profile, increase protein turnover, accelerate exercise adaptation, and (when replacing dietary carbohydrate) decrease the chance of cardiovascular disease, it should be clear that most people would do well to increase their consumption of lean meat. These are just a few of the displacing debates gaining momentum in the nutrition world. Throughout your lifetime, you’ll be inundated with new experts, new nutritional plans, and new "revolutionary systems." Rather than letting these new ideas be a source of frustration and confusion, do your best to get past the marginalia, to get past the differences between all the new programs, and try to discover for yourself the basic principles all the successful programs seem to be built upon. Most importantly, when faced with a choice between two good options, one of which may be marginally better than the other, but both of which would be an improvement over what you're currently doing, just pick one and go with it. You can optimize later, as long as you make an improvement now. There's no debating that. So imagine the dismay someone might experience when hearing that the experts are now bickering about the type of meat we consume. Many experts muddy the waters when discussing free range vs. grain fed meat, telling people that grain fed meat (the only kind you can find in many grocery stores in North America) is full of toxins, bad fats, and hormones. Sure, free-range meat is probably a better choice, although there’s little proof the supposed toxins and hormones actually get passed on to us. But again, imagine you’re someone with a lifetime of eating habits that 17 CHAPTER 2 – STRATEGIES FOR FAT LOSS the questions as simple and obvious, and always had all the answers." 2.1 Lean Eatin’ Part 1 by John M Berardi Therefore, it doesn't seem such a mystery why people buy into the gimmickry. Telling the people what they want to hear wins them over. The problem is that while radical diets, gadgets, and pills may work in the short run, they often compromise an individual's health and well-being more than the extra fat does if they're overweight. This makes the cost to benefit ratio ridiculously low. The other problem is that these strategies don't typically work in the long run. So if you're trying radical new methods, it's a safe bet to assume that after the "treatment" is over, you'll likely go back to normal. With summer fast approaching, "beach-think" has set in and the current most-popular question is, "Oh wise and mighty JB who knoweth and loveth the alimentary arts while abhorring all that is adipose, how might I battle my corpulence?" Okay, okay, it's more like, "Hey jackass, how do I get rid of my gut?" but a guy can dream of eloquent questions from glib readers, can't he? Fed up with answering the gut question for the bazillionth time, this article was born. In fact, this article is the transcript from one of the lectures I recently gave at Ian King's excellent Bigger, Stronger, Leaner! seminar in Toronto. If you think it's time to bring out those abs for summer, then this is the article for you! Gadgets and Gimmickry The science and art of eating for fat loss and muscle gain have become big business. Unfortunately, this big business, in the eternal quest to get paid, has taken the focus off excellent eating and excellent exercise regimens. Instead, with infomercials, marketing and advertising, and strategic alliances with the media (magazines, TV, etc), the diet and exercise industry has confused most people to the point that all they can do now is call up 1800 numbers or jump on a secure server with their credit card ready. Some of these infomercials not only ignore the role of diet and exercise, they try to convince you those things aren't necessary when you buy their fat melting vibrating belts and magic pills. Why has this transpired? Well, the answer is simple. And for three easy payments of $19.95, I'll tell you. No, no, just kidding. How about a quote instead? "Throughout history, the difference between scientists and physicians on the one hand, and quacks and promoters on the other, has been that the scientists and physicians have attempted to show both what they knew and what they didn't know while the promoters saw Now personally, I love being lean, but I also enjoy my good health. And my focus remains on using the basics of good, natural food selection and an active lifestyle that includes regular, preplanned physical activity. Anyone who's read my work knows that I'm not a big fan of prepackaged meals, gadgets or magic potions. As revolutionary as it sounds, I believe you can get lean by manipulating your diet and exercise alone. So the purpose of this article is to provide a scientific basis for making good food selections, the real "secret" behind getting and staying lean. More specifically, I'll discuss the following: • • • • • Why a calorie is not a calorie Why a protein is not a protein Why a carbohydrate is not a carbohydrate Why a fat is not a fat How to choose your food wisely Okay, let's dive in and prepare to "get your beach on." A Calorie Is Not A Calorie While the gurus and pundits of the past believed that all calories were created equal, and while much of the current dietetics herd still believes it, I'm here to tell you why it just ain't true. To do so, I'll focus on three main arguments: the Thermic Effect of Feeding (TEF), cross-cultural studies, and the effects of isoenergetic diets using different foods. 18 The TEF, as I've said many times before, represents the additional caloric expenditure (above resting metabolism) that it takes to digest, absorb, and process the food you eat. Studies on the thermic effect of different foods have been important in describing the different effects of the macronutrients on metabolism. The TEF lasts from between one to four hours after eating a meal. When adding up the thermic effects from each of your meals, this extra metabolism represents between 5% and 15% of your total daily energy expenditure. Therefore, if your daily energy expenditure is 3,000kcal, about 150 to 450kcal of that comes from the TEF. Interestingly, different macronutrients tend to have different effects on metabolism. Welle et al. (1981) and Robinson et al (1990) demonstrated that during a normal six hour period of rest and fasting (basal metabolism), subjects burn about 270kcal. When eating a single 400kcal meal of carbs alone (100g) or fat alone (44g), the energy burned during this six-hour period reached 290kcal (an additional 20kcal). Interestingly, when eating 400kcal of protein alone (100g) the subjects burned 310kcal during this six-hour period (an additional 40kcal). Therefore, protein alone had double the thermogenic power vs. fat or carbs alone! Swaminathan et al (1985) demonstrated that during a normal fasted 90-minute period, both lean and obese subjects burned about 110 calories. When consuming a 400kcal, fat only meal (44g), the lean subjects burned 125kcal (+15kcal) while the obese subjects only burned 110kcal (+0Kcal). This indicates that while the lean can upregulate metabolism when eating fat, the obese may, in fact, have a defect in their thermogenic response mechanisms for fat. When fed a 400kcal mixed meal (P+C+F), the lean subjects burned 130kcal (+20kcal) during the 90-minutes while the obese burned 125kcal (+25kcal) during the 90-minutes. These data demonstrate that mixed meals are more thermogenic than fat only meals and that lean people have a better TEF response than the obese. So now that you understand that different macronutrients (at the same energy intake) can alter calorie balance within a single meal, here's another interesting argument for the fact that all calories were not created equal. In a study by Campbell et al (1991), 6,500 rural and urban Chinese were compared to the US population norms for energy intake, macronutrient breakdown, and health. This is an important comparison due to the fact that obesity and cardiovascular diseases have reached epidemic proportions in North America while the prevalence is much lower in China. Check out this data on average nutrient intake: U.S.: • • • • • • • • Energy - 30.6kcal/kg Carbohydrate - 42% (224g) Fat Intake - 36% (85.86g) Alcohol - 7% Fiber - 11g/day Protein - 15% (80g) % Protein from Animal - 70% (56g) BMI (wt/ht*ht) - 25.8 China • • • • • • • • Energy - 40.6kcal/kg Carbohydrate - 71% (504g) Fat Intake - 14% (44g) Alcohol - 5% Fiber - 33g/day Protein - 10% (71g) % Protein from Animal - 11% (7g) BMI (wt/ht*ht) - 20.5 It's interesting to note that while the Chinese have a much lower body mass index (as represented by weight in kg/height squared in meters) and a much lower prevalence of obesity and cardiovascular disease, they eat about 25 to 35% more food than we do! Now, the Chinese tend to be more active than we are, but when the numbers were corrected for activity levels, the differences remain! Looking at the macronutrient breakdowns, the Chinese are on a high-carb diet, no doubt. But they're not fat. And while their protein intake, by percentage, is lower, they do get nearly as much total protein, by gram amount, as we do. Perhaps we could take a lesson from the Chinese. Clearly not all calories are created equal because if they were, the Chinese would 19 be fatter than we are! But instead, the average 100kg Chinese person gets to enjoy a 4060kcal diet while keeping his lean physique. food while staying leaner. Just ask the Chinese. A Protein Is Not A Protein I know, I know, that study is only epidemiological and therefore lacks some explanatory power, but stay tuned as I present two final studies to demonstrate that all calories were not created equal. In a study by Demling et al (2000), the researchers demonstrated that food choice and timing could be more important than total calorie intake. Before the study began, overweight police officers, eating about 2100 to 2300kcal per day, tipped the scales at 216lbs with 56lbs of fat mass (25% fat) and 158lbs of lean mass. They were eating about 74g protein, 380g carbs, and 56g fat. Since this is clearly a hypocaloric diet, they should've been losing weight. But they weren't. Unfortunately for these poor guys, they were eating only 10% of their calories at breakfast and a whopping 50% of their calories right before bed. In addition, 50% of their carb intake was sugar! After diet counseling, these guys still ate the same diet in terms of macronutrients, but they ate 70% of their calories during the active parts of their day and 80% of their carb intake was complex and low on the GI scale. At the end of twelve weeks these guys lost 3lbs of weight and 5lbs of fat while gaining 2lbs of lean mass. And this was without changing exercise habits! While these changes weren't huge, it's clear that food choices and timing make a difference. In another study by T-mag's own Doug Kalman et al (2001), Doug showed that a 1200kcal, high-protein (47%P, 36.5%C, 16.5%F) diet was more effective than a 1200kcal, moderateprotein (24.5%P, 48.3%C, 27.2%F) diet for fat loss. Subjects in the high-protein group lost 6.3lbs of body weight, 5.3lbs of fat weight, and only 1lb of lean weight. The moderate protein group lost 3.1lbs of body weight, no fat weight, and 4.5 whopping pounds of lean weight. Try telling these subjects that a calorie is a calorie! In the end, there clearly are ways to burn more calories and lose more weight while eating diets differing in macronutrient content but similar in energy intake. In addition, if you can believe it, there may even be ways to eat more In this section, I'd like to demonstrate that not all proteins were created equal. Specifically, I'll briefly discuss whey and casein protein, fast and slow protein, animal and vegetable protein, cod/fish protein and soy protein. The topic of whey vs. casein has been discussed ad nauseum lately so rather than belabor this issue, I'll quickly summarize a few studies. Demling et al (2000) compared two groups on a 2100 to 2300kcal diet containing 143gP (26%), 286gC (52%), and 49gF (20%). Both groups weight trained for twelve weeks but received 75g of their daily protein intake from either a whey-based drink or a milk-protein isolate drink (80% casein, 20% whey). At the end of the study, the milk-protein isolate group lost more fat (15.4lbs vs. 9.2lbs), gained more lean mass (9lbs vs. 4.4lbs), and gained more upper and lower body strength than the whey group. It appears that milk protein isolate ingestion, when on a training program, may be a better way to enhance fat loss and muscle gain. Lands et al (1999) showed that when supplementing with 20g of whey or casein for three months, the whey group had upregulated their antioxidant defense systems and had increased performance in an anaerobic exercise task. The casein group didn't improve on any of the above parameters. Therefore whey may be better for antioxidant protection. Since the fast vs. slow debate focuses on whey (fast) vs. casein (slow), let's address that research here. In studies by Boirie et al (1997) and Dangin et al (2001), it was shown that whey protein is better for up-regulating protein synthesis while casein protein is better for down-regulating protein breakdown. Not much more has to be said about this since it's been discussed about a thousand other times on this site alone. The take-home message from these studies is that a milk protein blend or a supplement containing whey + casein may be your best bet for body composition improvements. 20 Next up, what about those kooky vegetarians? Well, in comparing an omnivorous diet (meat containing) with a vegetarian diet, Campbell et al (1995, 1999) demonstrated that strength gains and body composition improvements are impaired when meat is removed from the diet. In their studies, subjects weight trained for twelve weeks while consuming a 2300kcal diet consisting of 70-90gP (12-15%), 267-317gC (49%), and 82-87gF (7-11%). The only difference between groups was the fact that one group ate a meat-free diet while the other group ate meat. At the end of the twelve weeks, the meat eaters lost 2.8lbs of fat while gaining 3.74lbs of lean tissue. The vegetarians, on the other hand, lost no fat weight and lost 1.76lbs of lean tissue. Bottom line, meat seems to be an essential part of the diet. Regarding fish in the diet, Lavigne et al (2001) demonstrated that cod protein was better than soy or casein for increasing muscle glucose sensitivity and for preventing insulin resistance in high-fat fed rats. Since codfish has a favorable omega-3 profile, the researchers duplicated their work using only the protein component of cod and the benefits remained the same. This indicates that eating fish may improve your carbohydrate sensitivity and ultimately your body composition and these effects may be independent of the fatty acid profile. Finally, Lohrke et al (2001) showed that growing pigs fed a diet consisting of soy as the only source of protein had lower body weights, amino acid imbalances, increased cortisol levels, and increased muscle breakdown. The casein-fed pigs grew normally. This study indicates that a diet containing exclusively a low quality protein (soy in this case) may interfere with normal growth and development. So, how do we use this information to our advantage? Well, since different protein sources confer different benefits, your best bet is to eat some fish protein (cod, salmon, tuna), some lean meat protein, and some milk protein isolates or whey/casein blends each day. Eating from a limited list of protein sources is a big mistake. Depending on their individual needs, my clients typically eat a different protein source with every meal so that by the end of the day they've gotten complete protein from egg whites, fat free cheese, milk protein isolate shakes, cottage cheese, salmon or tuna and lean beef, not to mention the incomplete sources like mixed beans and mixed nuts. Summary of Part I • • • • • • • • With all the media hype out there, the key to staying lean and mean is still diet, specifically, good food choices. A calorie is not a calorie because the macronutrient content of each meal affects the body's response to the feeding. That basically means you could change your body composition by eating the same amount of calories each day, but making different food choices. Meal timing also plays an important role. A high protein diet may be better than a moderate protein diet for fat loss. A protein is not a protein because different kinds of proteins affect the body in different ways. Milk protein isolate (80% casein, 20% whey) may be better than whey alone if your goal is fat loss. Whey looks like it's better for antioxidant protection, however. A supplement containing whey + casein may be your best bet for body composition improvements. Meat eaters can lose fat faster and gain more muscle than vegetarians, even if the vegetarians eat the same amount of calories and get the same amount of protein. Eating fish may improve your carbohydrate sensitivity and ultimately your body composition. Soy still sucks as a primary protein source. Next week, I'll discuss why a carb is not a carb and why a fat is not a fat, plus provide a list of 2.2 Lean Eatin’ Part 2 by John M Berardi With summer fast approaching, "beach-think" has set in and the current most popular question is, "Oh wise and mighty JB who knoweth and loveth the alimentary arts while abhorring all that is adipose, how might I battle 21 my corpulence?"

If you think it's time to bring out those abs for summer, then this is the article for you! Last week, in Part I, I wrote about how all calories and all proteins aren't all equal, despite rights guaranteed to them by the Constitution. Carrying the argument further… A Carbohydrate Is Not A Carbohydrate In this section, I'd like to demonstrate that not all carbohydrates were created equal. Specifically, I'll briefly discuss: 1. The insulin index vs. the glycemic index 2. The superiority of low-GI and II diets 3. The difference between liquid carbohydrates While older carbohydrate classification schemes were centered on the notion of simple vs. complex carbohydrates (a structural classification), newer schemes focus more appropriately on the absorption profiles (glycemic index) and physiological effects (insulin index) of these carbohydrates (a functional classification). The Glycemic Index (GI) is a classification scheme based on the blood glucose rise after consuming a carbohydrate food. This measure is based on the absorption profile of the food and was originally considered an indirect, but adequate measure of the insulin response to food. The assumption was that the insulin rise would be proportional to the glucose rise. However, recent research has demonstrated a dissociation of the glycemic response and the insulin response to the food. Therefore the insulin index was created. The Insulin Index (II) is an index of the magnitude of insulin secretion as a result of food ingestion. Of course, this is the direct measure that the glycemic index could only approximate. Since insulin is a tricky hormone to manage, it's best to know exactly what's happening with this guy, especially if you have poor insulin sensitivity or poor carbohydrate tolerance. Studies by Holt et al (1996) and Ostman et al (2001) highlighted some of these differences between glycemia and insulinemia. Interestingly, while the glycemic and insulin indices of many foods were similar, some foods caused unpredicted responses. As shown in the following graph, foods like yogurt and milk had relatively low-glycemic indices, but very high insulin indices. White and brown rice, on the other hand, had high-glycemic indices, but low insulin indices. The point here is that if you want to effectively manage body composition, you should choose your carbohydrates based on both the glycemic and insulin indices. Unfortunately, there are only limited insulin data out there, leading us to continue to rely in some cases only on the glycemic index. More complete glycemic and insulin indices can be easily located by doing an Internet search on these two terms. So the next appropriate question would be, "What does the literature say about low GI and II diets vs. higher GI diets?" Well, here's a summary: Ludwig et al (2000) described the following list of benefits for eating a low GI diet: • • • • • • Better nutrition (better micronutrient profile and more fiber) Increased satiety Decreased hunger Lower subsequent energy intake (second meal effect) Fat loss Better fasted insulin and glucose In a study by Agus et al (2000), it was demonstrated that during a short, 6-day, lowcalorie diet, a low-GI carb intake preserved metabolism and enhanced fat loss vs. a highGI diet. The low GI group saw a 5% decline in metabolic rate and a 7.7lb weight loss while the high-GI group saw an 11% decline in metabolic rate and a 6.6lb weight loss. In these 22 subjects, fasted glucose and insulin values were lower in the low-GI group, indicating better glucose and insulin sensitivity. Spieth et al (2000) and Ludwig et al (2000) showed that 4 months of low-GI eating was superior to 4 months of high-GI eating in overweight teens. The low-GI group lost 1.5 points on the BMI scale and 2.2 lbs while the high-GI group gained 2.88lbs and increased their BMI. In addition, these studies showed that a low GI meal reduced food intake during subsequent meals while the high GI meal lead to overeating. Finally, Pawlak et al (2001) showed that in rats, a low-GI diet led to decreased fasting insulin and glucose values, decreased fat mass, and decreased insulin and glucose values during a glucose tolerance test. Therefore, body comp as well as glucose and insulin sensitivity improved. The bottom line here is that when all else is equal, a diet containing mostly low-GI carbohydrates is superior to a high-GI diet for losing fat, preserving metabolic rate, and maintaining healthy insulin sensitivity and glucose tolerance. Next, I'd like to illustrate the differences between popular liquid carbohydrates including maltodextrin, dextrose, fructose, and sucrose. Maltodextrin is a glucose polymer (a string of glucose units put together, similar to the protein peptide). It is therefore, by definition, a complex carbohydrate. However it's more complex nature does NOT slow digestion. Therefore, the GI and II remain high. Maltodextrin is the absolute best carbohydrate to consume during exercise for rapidly delivering blood glucose and for muscle glycogen recovery. It's also best for fluid uptake. Dextrose (glucose) is a simple carbohydrate unit (similar to the amino acid). While it's good for exercise situations (malto is better), you're probably better off adding some dextrose to your maltodextrin formula. A little bit of dextrose may enhance the already excellent fluid uptake that occurs with maltodextrin during exercise. structure, it can possibly cause GI problems and/or decrease fluid uptake with exercise. Fructose, unlike other simple carbs, has to be "treated" in the liver and it reaches the muscle slowly. Finally, sucrose consists of glucose and fructose units bonded together. Therefore, upon digestion, you get glucose and fructose in the GI (and the benefits and consequences of each). Based on the three studies I reviewed (Blom et al 1987, ven Den Burgh et al 1996, Piehl et al 2000), it appears that dextrose is 72% faster than fructose for muscle glycogen resynthesis. As a result, at the end of 8 hours, muscle glycogen was 30% higher with dextrose ingestion. However, in another study, at the end of 4 hours, muscle glycogen was 15% higher with maltodextrin ingestion vs. dextrose. So dextrose kicks fructose's butt although malto beats up on dextrose. A Fat Is Not A Fat In this section, I'd like to demonstrate that not all fats were created equal. Specifically, I'll briefly discuss: 1. Fat Structure - Fatty Acid Chains and TGs 2. MCTs - Medium Chain Triglycerides 3. Olive Oil - Monounsaturated Fatty Acids 4. CLA - Polyunsaturated Fatty Acids 5. Fish Oil - Omega 3 Polyunsaturated Fatty Acids As discussed in The Fat Roundtable, there are three different types of fatty acids; saturated (coming from animal fats), monounsaturated (coming from olive oil and avocados), and polyunsaturated (coming from flax oil, hemp oil, fish oil, canola oil, safflower oil, etc). Dietary fat, rather than simply floating around as free fatty acids, typically is packaged up in the form of a triglyceride. Basically, a triglyceride consists of 3 fatty acids (usually all of the same type) bound together by a glycerol backbone. Essentially, the glycerol backbone has 3 carbons and a fatty acid is attached (via a dehydration/synthesis reaction) to each of the 3 carbons. Fructose is a simple carbohydrate unit, but it's structurally different from glucose. Due to its 23 Based on this structural phenomenon, scientists have recently begun exploring an interesting development in fat science. They've begun making "structured lipids." In essence what they're doing is making diacylglyerols (2 of the carbons have fatty acids attached while 1 does not) and special triacylglycerols (where there are fats of different lengths and properties attached to each carbon). In clinical studies, these structured lipids have been shown to increase protein synthesis in patients suffering from wasting. In addition, these fats are easily oxidized (like the long chain fatty acids in fish oil) which leads to a thermogenic response rather than a storage response. As a result these structured lipids are now being heavily studied. While they're not on shelves yet, I wouldn't be surprised if these structured lipids become food additives in the near future. MCT's and CLA, probably due to their early introduction to the weightlifting scene and the huge media hype associated with this introduction, have gotten a bad reputation. These fats may, in fact, assist in weight loss. MCT's, due to their medium chain length, are easily oxidized by skeletal muscle. This is due to the fact that MCT's are quickly and easily transported to the fat furnace, the mitochondrion. As a result, research (Hill et al 1989) has demonstrated that TEF (thermogenic effect) with MCTs is double that of other fats, making it comparable to protein in this regard. CLA has remained a relative mystery to the research community. This is probably due to the various forms (isomers) of CLA. Regardless, some research (Blankson et al 2000) has shown that 12 weeks of CLA supplementation (at doses above 3.4g/day) can increase LBM and decrease fat mass vs. olive oil. While the olive oil group gained 1.5 lbs of fat and no lean body mass, the CLA group lost 4.5 lbs of fat and gained 3 lbs of LBM. Speaking of olive oil, even this "good fat" is better than saturated fat for body composition. In a study comparing safflower oil, beef fat, palm fat, and olive oil, it was shown that olive oil leads to a 14% higher oxygen consumption rate than the other fats. Finally, if you've been around the T-mag community for a while you'll know that my favorite fats are those in fish oil. Delarue et al (1996) showed that fish oil supplementation (6g/day added to the diet) dramatically changed the metabolism of fats and carbohydrates. During an OGTT (oral glucose tolerance test drinking a big 75g whack of liquid sugar and measuring the subjects for 2 hours afterward), the fish oil group burned 27g of fat vs. 20g in the placebo group. The fish oil group also burned 28g or carbs while storing 36g and the placebo group burned 51g of carbs while storing only 14g. In addition, baseline insulin was 30% lower in fish oil group and insulin responses to OGTT were 50% lower in the fish oil group. What this tells us is that fish oil allows the body to burn more fat and store more muscle glycogen, repartitioning fuel away from fat cells toward muscle cells. Since fish oils are polyunsaturated fats, it's important to not only increase fish-oil intake, it's important to shift the ratio of polyunsaturated fat to saturated fat (P/S). Van Marken, Lichtenbelt et al (1997) showed that the polyunsaturated fat to saturated fat ratio is important to metabolic rate. A higher ratio of P/S leads to metabolic increases (22% increase in TEF and 3% increase in daily RMR). So, if there's one thing you need to take from this discussion, I think it should be that, all else being equal, the fat composition (not just total intake) of your diet is very important to your body composition. Saturated fats, while necessary to a small extent, should only make up a small part of your diet while other fats like olive oil, fish oil, flax oil, MCTs, and CLA all have a place on your plate. This way you can get the same amount of daily energy from fats while gaining lean mass and without gaining body fat. Choosing Your Food Wisely 24 So, with all the research out of the way, I hope that I've made a good argument for the fact that while total energy intake is important to energy balance, smart macronutrient choices go a very long way in shifting the energy balance equation in your favor. But to drive the point home, I'd like to give a living example of this fact. One of my clients told me that he was a big fan of my work and my nutritional advice. However, he was convinced that his body simply couldn't get lean. The problem was that this gentleman got fat by using the calorie counting method. In fact, he used my very own Don't Diet method (the nerve of him!). He exercised regularly, training with weights 4x per week and doing daily cardio (mixing up interval exercise with endurance type exercise). In addition, he always ate about 500 calories below what his maintenance should have been. Yet he got fat anyway and was walking around at 25% body fat. He thought he was destined to be chubby forever. So, was it true? Was he really fat loss resistant? Had my Don't Diet plan failed? I was perplexed so I had him write down everything he ate for a week. When sitting down with him a week later, the answer to his dieting woes was obvious. He was eating all the wrong foods. His diet was full of the media promoted fat free/super sugared/over processed/synthetic/bleached supermarket foods. He believed that the foods he was choosing were good for him, but in fact, he was eating a diet designed for fat storage. When calculating the numbers, it worked out to be about 2,300 kcal at 30% protein, 50% carbs, and 20% fat. But the foods he used to make up these numbers were atrocious. He was eating way too much saturated fat, was drinking way too many whey protein shakes with milk, and was consuming too much sugar and processed, high-GI carbohydrate. There was very little natural fiber in his diet and he rarely ate vegetables or fruit. No wonder he couldn't lose weight! Now, how on earth could he have believed that his diet was good? Well, although this data is a little old, I wanted to share it with you anyway because it's very telling about the power of marketing. In 1992 the National Cancer Institute spent $400,000 on an ad campaign to encourage the consumption of fruits and vegetables. That same year Kelloggs spent 32 million advertising Frosted Flakes alone! No wonder people don't know what foods are good for them! So, back to the client. Well, it turns out that he had been down this road before. When he first started gaining weight, he decided to go on a diet program. He followed a ridiculous, muscle wasting, low calorie diet full of sweeteners and terrible tasting foods. And he lost some weight. But the minute he went back to eating what he thought was healthy and sensible (as described above); he gained all the fat back and then some! So, now that I had him under my tutelage, what was the solution? First I taught him where the produce aisle is. We gave him a list of the foods he could choose from. In addition, I taught him to combine his meals such that he was eating lean protein, good fats, and lots of fruits and veggies. We didn't count calories or pre-plan meals; we just made sure he had enough protein in the diet (200g). And guess what? Months later, he's still dropping fat while maintaining his lean mass. He's eating far more calories than he ever had before and enjoying meals more than he ever had before. In addition, he has a better health profile (blood chems) than before. The bottom line is that diet isn't that hard. When you feed the body wholesome foods, the appetite regulates itself and you don't have to monitor very much. However, by harnessing the powers of good food selection and smart calorie counting, weight loss comes easy! Here are some basic rules for how to improve your eating habits: • • Get used to the taste of food without dressings, sweeteners, etc. Ultimately you'll grow to like the natural taste of foods you once though tasted bland. Try to eat more like a true vegetarian (i.e. the bulk of the diet should come from fruits, veggies, unprocessed and unbleached food). But don't get me wrong; I don't want you swearing off meat. 25 • • • • • • • • "Supplement" your unprocessed vegetarian-like diet with the high-protein foods discussed above. Add unheated healthy oils to your foods. Drink only calorie-free beverages (green tea, water, etc.). Unfortunately the worst foods usually are the most convenient and the most processed foods. Avoid eating for convenience alone. Avoid any easy-to-prepare breakfast foods (waffles, french toast, etc) as they're loaded with fattening trans-fatty acids. Avoid products containing the ingredients or words "partially hydrogenated," "high fructose corn syrup," etc. Avoid fast/fried food. Avoid foods or meals that are high in both fat and carbohydrate. In addition to these rules, here's the list of food choices that I give to many of my clients. These foods should make up about 80% of your daily diet and, as indicated above, you should be eating many of these foods each day, not simply picking one or two selections to eat all the time. • Fish oil For active individuals, the other 20% of your daily calories should come from the following sources (in order to enhance your recovery from intense exercise). The liquid meal should come during and after exercise while the second high-carb meal should come about 1-2 hours later. Liquid meal (during exercise and immediately post exercise): • • Protein: Whey hydrosylates/Isolates Carbohydrates: High-GI liquid, Glucose (dextrose), Maltodextrin Solid meal (2 hours post exercise): • • Protein: Plain yogurt Carbohydrate: High GI, solid-fiber cereal In addition, here's the other list that I give to my clients. These are foods to avoid at all costs: Proteins: Protein: • • • • • • • Fish: Salmon, Tuna, Cod Eggs Chicken breasts Cottage cheese Milk protein isolates Whey-casein blends Lean Red Meat Carbohydrates: • • • • • • Vegetables Mixed beans Low-GI fruits Oatmeal/Oat bran Mixed-grain bread Small amounts of protein-enriched pasta • • • • • Fatty meats Fatty dairy Most lunch meat Large amounts of milk Large amounts of soy Carbohydrates: • • • • • • • • Regular bread Added sugar Most cereals Soda Fruit juice Bagels Fruit bars Candy Fats: Fats: • • • • Flax oil EPA/DHA Olive oil Mixed nuts (no peanuts) • • • • Margarine Vegetable oil Corn oil Heated/fried oil 26 In conclusion, food selection is one of the more important determinants of your body composition. Using the rules above, you can make your fat loss quest much easier than you ever imagined! 27 CHAPTER 3 – STRATEGIES FOR MUSCLE GAIN 3.1 Massive Eating Part 1 by John M Berardi Pop Quiz, Hotshot Pretend you're back in high school and mean ol' Mr. Berardi has just passed out a pop quiz. Luckily, there's only one question: Which of the following statements is true? A) Most people succeed in training well enough to grow, but they fail in eating well enough to grow. B) Most people eat well enough to grow, but they don't train well enough to grow. Pencils down. Okay, which is it? If you said "A," give yourself a gold star. But don't feel too badly if you chose "B." To an extent, both answers are correct. Most people probably train and eat incorrectly! But if I had to pick one answer that was more true than the other, I'd say "A" would be the best choice. If you're not growing, it's probably your diet, not your training, that's holding you back. With this article I'm throwing down the gauntlet. This is your wake up call if you've ever made any of the following statements: "I eat a lot of food. In fact, it feels like I'm eating all day! But I just can't get any bigger." "I can't gain a pound of muscle. My parents are both skinny, so it must be genetic." "I've always had a fast metabolism. That's why I can stay lean but can't get any bigger." "I'm scared to go on a bulking diet because I don't want to lose my abs." "I've tried mass-building diets before and put on a little muscle, but most of the weight I gained was fat." Sound familiar? Then this article is for you, toothpick legs. What You're Doing Wrong Now you may be asking, "If I'm not eating well enough to grow, Mr. Smartypants, what am I doing wrong?" In my opinion, there are three major things that most people do incorrectly when trying to gain muscle mass: 1) They don't understand energy balance (calories in vs. calories out). 2) They don't eat the right foods at the right times (poor meal combinations). 3) They don't learn their physiological responses to nutrients (insulin sensitivity, carb, and fat tolerance). Below (and in Part II) I'll describe practical ways to fine tune all three. By the end of this series, you should know how much food you need to grow, what combinations of foods you should eat and when you should eat them, and how to figure out your own personal, individualized macronutrient needs. Energy Balance: You might be surprised! So what is energy balance? Here's the simple equation: Energy Balance = Energy Intake - Energy Expenditure Energy intake is made up of what you eat and drink. Energy expenditure is made up of several factors including resting metabolic rate (RMR), calorie cost of activity, thermic effect of food (TEF), and adaptive thermogenesis (the X factor). The balance of intake and expenditure is an important factor in weight gain or loss. If you have a positive energy balance (intake exceeds expenditure), you gain weight. A negative energy balance (intake is less than 28 expenditure) dictates that you'll lose weight. Simple enough. Remember, however, that energy balance is only one factor in getting massive (or getting lean for that matter). And although it's the most basic and simplest part of understanding your needs for growth, ironically, most people totally screw it up! So let me be your metabolic guide. Below I'll provide some practical ways to navigate through the harsh jungle of energy balance equations so that you'll emerge ready to tackle the challenge of muscle growth. Pick up your pencils again, class. Better yet, grab a calculator! Step #1: Resting Metabolic Rate Resting metabolic rate (RMR) is the energy it costs the body to basically keep alive. This doesn't include the costs of getting your butt out of bed and moving around; those numbers are calculated in later. Although you might not guess it, about 50 to 70 percent of your entire day's calorie expenditure is a result of the RMR. So, let's figure out your RMR right now. Determining RMR: To start off with, you need to take your body weight in pounds and convert it to kilograms. (International readers, please bear with us silly non-metric Americans for a moment.) This is a simple conversion. Just divide your body weight by 2.2. Next you take your percent of fat and multiply it by your body weight (which is now in kilograms). This will give you your fat mass (FM) in kilograms. Next simply subtract this number from your total weight in kilograms and you'll have your fat free mass (FFM) in kilograms. Before we go on, why don't we try this out on me. Since I'm an athlete with a body weight of 200lbs at 5% body fat, I'd take my total body mass and divide it by 2.2: Total body mass in kilograms = 200lbs / 2.2 = 91 kg Next I'd multiply this kilogram number (91 kg) by my percent of body fat. Remember, percents are really decimals so 5% equals 0.05, 12% bodyfat will be .12 etc. Fat Mass = 91kg x 0.05 = 4.55kg FM Next I subtract this fat mass number (4.55 kg) from my total body mass (91kg): Fat Free Mass = 91kg - 4.55kg = 86.45kg Therefore my fat free mass is 86.45 kilograms. From that I can determine my RMR. The formula for RMR is as follows: Resting Metabolic Rate for Athletes (in calories per day) = 500 + 22 x fat free mass (in kilograms). Again, for me, I'd multiply 22 times my fat free mass and add 500 to that number as shown below: RMR= 22 x 86.45 + 500 = 2402 Therefore my resting metabolic rate is about 2400 calories per day. Everyone have their RMR figured out? Good, let's move on. Step #2: Cost of Activity The Cost of Activity represents how many calories are required to move your butt around during the day. This includes the cost of walking out to your car, scraping the ice off the damn thing, driving to work, pinching the secretary's ass, going to lunch with the boys, and of course, training after work. These factors make up about 20 to 40% of your daily caloric intake based on your activity level. So let's figure out your costs of activity. I'll use myself as an example again. Determining Activity Costs: Cost of Daily Activity is equal to the RMR you calculated above multiplied by an activity factor that fits your daily routine. I've listed some common activity factors below. 29 Activity Factors: 1.2-1.3 for Very Light (bed rest) 1.5-1.6 for Light (office work/watching TV) 1.6-1.7 for Moderate (some activity during day) 1.9-2.1 for Heavy (labor type work) Note: Don't consider your daily workout when choosing a number. We'll do that later. With this information we can get back to determining my calorie needs. Since I work at a university, most of my day is pretty sedentary. Even though I run back and forth between the lab and classes, I've selected 1.6 as my activity factor. Therefore the amount of calories it takes to breathe and move around during the day is about 3800 calories as shown below: RMR x Activity Factor = 2400 calories x 1.6 = 3800 calories Costs of Exercise Activity: Next, we need to determine how many calories your exercise activity burns so that we can factor this into the totals. Exercise activity can be calculated simply by multiplying your total body mass in kilograms (as calculated above) by the duration of your exercise (in hours). Then you'd multiply that number by the MET value of exercise as listed below. (MET or metabolic equivalent, is simply a way of expressing the rate of energy expenditure from a given physical activity.) MET values for common activities: high impact aerobics... 7 low impact aerobics... 5 high intensity cycling... 12 low intensity cycling... 3 high intensity walking - 6.5 low intensity walking - 2.5 high intensity running... 18 low intensity running... 7 circuit-type training... 8 intense free weight lifting... 6 moderate machine training... 3 So here's the formula: Cost of Exercise Activity = Body Mass (in kg) x Duration (in hours) x MET value And here's how I calculate it for myself: Exercise Expenditure for weights = 6 METS X 91kg x 1.5 hours = 819 calories Exercise Expenditure for cardio = 3 METS X 91 kg x .5 hours = 137 calories Add these two together and I burn 956 total calories during one of my training sessions. Since my training includes about 90 minutes of intense free weight training and 30 minutes of low intensity bicycling (four times per week), my exercise energy expenditure might be as high as 1000 calories per training day! The next step is to add this exercise number to the number you generated when multiplying your RMR by your activity factor (3800 calories per day in my case). So 3800 calories + about 1000 calories = a whopping 4800 calories per day! And we're not done yet! (Note: I rounded 956 up to 1000 for the sake of simplicity. If you're a thin guy trying to gain muscle, it's better to round up anyway than to round down.) Step #3: Thermic Effect of Food TEF is the amount of calories that it takes your body to digest, absorb, and metabolize your ingested food intake. This makes up about 5 to 15% of your total daily calorie expenditure. Since the metabolic rate is elevated via this mechanism 10 to 15% for one to four hours after a meal, the more meals you eat per day, the faster your metabolic rate will be. This is a good thing, though. It's far better to keep the metabolism high and eat above that level, than to allow the metabolism to slow down by eating infrequently. Protein tends to increase TEF to a rate double that of carbs and almost triple 30 that of fats so that's one of the reasons why I'm a big fan of protein meals. weather induces increased metabolic activity and heat production). Determining the Thermic Effect of Food: With all that said, you don't need to do any math on this part or fiddle with your calorie total. This is just something to keep in mind. To determine the TEF, you need to multiply your original RMR value (2400 in my case) by 0.10 for a moderate protein diet or 0.15 for a high protein diet. So this is what the formula looks like: TEF = RMR x 0.10 for moderate protein diet (1 gram per pound of bodyweight) TEF = RMR x 0.15 for high protein diet (more than 1 gram per pound of bodyweight) Since I eat a very high protein diet (about 350 to 400 grams per day), I use the 0.15 factor and my TEF is about 360 calories per day as displayed by the calculation below: Thermic Effect of Food = 2400 calories x 0.15 = 360 calories per day Now add that to your calorie total. Step #4: Adaptive Thermogenesis I like to call Adaptive Thermogenesis the "X factor" because we just aren't sure how much it can contribute to daily caloric needs. Some have predicted that it can either increase daily needs by 10% or even decrease daily needs by 10%. Because it's still a mystery, we typically don't factor it into the equation. Just for interest's sake, one factor included in the "X factor" is unconscious or spontaneous activity. Some people, when overfed, get hyper and increase their spontaneous activity and even have been known to be "fidgety." Others just get sleepy when overfed - obviously the fidgeters will be burning more calories that the sleepy ones. Other factors include hormone responses to feeding, training, and drugs, hormone sensitivity (insulin, thyroid, etc), stress (dramatically increases metabolic rate) or temperature induced metabolic changes (cold Step #5: Putting it all together Okay, so how many damn calories do you need to consume each and every day? Well, adding up RMR plus activity factor (3800 calories in my case), cost of weight training (819 calories), cost of cardio (137 calories), and TEF (360 calories), we get a grand total of about 5116 calories! (Remember, that's just my total. You'll get a different number.) Now that's a lot of food! And I must eat this each and every day when I want to gain weight. Are you surprised at how many calories I need? Most people are. So the next time you complain that you're "eating all day and can't gain a pound" you'd better realistically evaluate how much you're really eating. If you're not gaining a pound, then you're falling short on calories. The Secret is in the Surplus! So at this point, the keen T-mag readers that aren't afraid of massive eating might ask the question, "Since this is technically just your maintenance level, how can you get bigger by eating this amount? Wouldn't you need more?" The answer is simple. Since I train only four days per week this diet would meet my needs on those four days. But on my three off days per week I'd be in positive calorie balance by about 1,000 calories per day! (That extra thousand calories isn't being used when training, in other words.) This adds up to a surplus of 3,000 calories per week. And this is where the growth happens! I especially like this "staggered model" because rather than trying to stagger your calorie intake on a daily basis by eating different amounts of food on different days, I let my training cycle my calories for me. This way I can eat the same thing every day while preventing my body from adapting to that habitual level of intake. Just like we vary our training to prevent adaptation, prevention of 31 dietary adaptation is one of the secrets to changing your body composition. At this point, I want to stop and give you a week to think about your energy needs. Go do the math if you haven't already, figure out how many calories you need, and take some time to compose yourself. After you've realized that you've been grossly under-eating, start thinking about ways to add calories to your diet. In the next installment we'll discuss how to design an eating program that's individualized for your own needs. We'll also get down to the nitty-gritty and talk about what kinds of foods you should and shouldn't be eating. I'll meet you back here next week! if you always have high levels of blood fats and carbs in the presence of insulin (the kind your body makes, not the kind that comes in a syringe), your muscles will slow their uptake of nutrients and all that fat and carbs will feed the fat cells. Can you say Shamu? 3.1 Massive Eating Part 2 by John M Berardi Before you make a rash decision and try to eliminate insulin, I've got to let you know that insulin is very anabolic. It's responsible for carb and amino acid delivery to the muscles for recovery and growth. So you need insulin, but you need to control it. And when you eat to promote insulin surges, you've got to be sure that you have the ideal profile of macronutrients in your blood to ensure that this insulin surge leads to muscle gain and not fat gain. This is where meal combinations come into play. Now that I know how much to eat, what's next? Let's start with some meal combinations to avoid. Eating to get massive is a juggling act between three important concepts. As I stated in Part I, energy balance is only one. In focusing only on energy balance, individuals are ignoring the acute effects of eating on hormones, metabolism, and energy storage. So someone who argues that calorie balance is the only determinant in changing body composition is making the situation too simplistic. Avoid meals containing fats and carbs One of the goals of eating to grow should be to maximize the muscle gain to fat gain ratio. Basically you want to pack on the most muscle with the least amount of fat gain. To do this you need to understand which meal combos to pursue and which to avoid. The foundations of my recommendations in this area are based on the avoidance of a nasty scenario. The worst case scenario for someone trying to pack on muscle while minimizing fat gain is to have high blood levels of carbs, fat, and insulin at the same time. This is nasty because chronic elevation of insulin can increase the rate of transport of fats and carbs into fat cells. Although initially insulin shuttles nutrients into muscle cells, chronic insulin elevation will cause the muscles to become insulin resistant and refuse to take up nutrients. The adipose tissues, however, are greedy little pieces of cellular machinery and continue to take up nutrients at a rapid rate. So Unfortunately, this is the typical meal of the Western diet. As a result, it's no wonder that obesity is an epidemic. Meals with a high carbohydrate content in combination with highfat meals can actually promote a synergistic insulin release when compared to the two alone. High fat with high-carb meals represent the worst possible case scenario. Now, some people have argued that fat lowers the glycemic index of foods and should therefore be included in carb meals. But remember, the glycemic index only gives a measure of glucose response to a meal, not insulin response. And sometimes the glucose responses to a meal and the insulin responses to a meal aren't well correlated. So although you might be slowing the rate of glucose absorption into the blood by adding fat to your meals, you'll promote high blood levels of fats, carbs, and insulin. And that's a no-no! Avoid meals high in carbs alone Ironically, since the liver converts excess carbohydrates into fats, a very high carbohydrate meal can actually lead to a blood profile that looks like you just ate a high carb and high-fat meal! That's why high-carb diets 32 don't work any better than ones rich in fats and carbs. High carb meals easily promote high blood levels of fats, carbs, and insulin, too. Okay, so now that we know which meal combinations are evil. Let's be proactive and talk about what meal combinations to concentrate on. Eat meals containing protein and carbs (with minimal fat) It's well known in the research world that eating carbs and protein together also creates a synergistic insulin release (much like the fat and carb meals above). But in this scenario, that insulin release is just what we want. By having a few meals per day that cause high blood levels of insulin, carbs, and amino acids (as long you don't have chronic high blood levels of insulin all day long), the body tends to become very anabolic, taking up all those carbs and amino acids into the muscle cells for protein and glycogen synthesis. And since there's no excess fat for the fat cells, fat gain is minimized. Obviously this combination is beneficial during the post-workout period, but in addition you might want one or two additional insulin spikes per day to promote anabolism during a mass phase. Again, as long as you aren't elevating insulin all day long, you won't become insulin resistant. At this point some may argue that although this scenario might not promote fat gain, those high insulin levels will prevent fat breakdown (lipolysis). And they're completely correct! But you have to understand that most meals (unless they contain only certain types of protein) will elevate insulin levels to the point that lipolysis is prevented. So you can't escape that unless you eat a ketogenic diet with only specific types of low insulin releasing proteins. But since ketogenic diets don't put on muscle mass and there are all sorts of problems associated with them, I think they should be avoided. Since muscle gain is the goal, two or three meals per day of anabolism are necessary to get bigger and that means protein plus carbs with minimal to no fat. Eat meals containing protein and fat (with minimal carbs) Although it's desirable to eat some meals each day that release lots of insulin, upregulate protein synthesis, and fill up carb stores, it's advisable to avoid too many such meals. I discussed the reasons for this above (reduced insulin sensitivity and prevention of fat burning), but also, since we all know that essential fatty acids are so important to health and favorable body composition, eating protein and carb meals all day will prevent the ingestion of healthy fats. And that's no good. In an attempt to balance out your two or three carb plus protein (minimal fat) meals each day, you should be eating an additional two to three meals consisting of protein and fat with minimal carbs. Taking in 30% of each major class of fatty acids (polyunsaturates, monounsaturates, saturates) is a good mass building tip when thinking about which fats to consume. Taking a step back, the purpose of protein plus fat meals is to provide energy and amino acids without causing large, lipolysis-preventing insulin spikes. In addition, after fatty meals that contain no carbs, the body oxidizes less carbs (more carbs are stored and retained in the muscle as glycogen) and burns more fat for energy. So basically you'll be burning fat for energy and storing carbs in the muscle after such meals. I hope that it's clear now that by properly combining meals, you can use the acute effects of food to your advantage. Eat protein plus fat during some meals and you may be burning fat during certain portions of the day. Eat protein plus carbs for some meals and you may be growing during other portions of the day. Although I know some will think this is blasphemy, this type of eating may actually help you get bigger while reducing your body fat during the same training phase. Real Meals Don't you hate it when you read a diet article only to find yourself asking, "So what exactly do I eat anyway?" Well, here are some examples of typical meals to consume when following this program: Protein plus carb meals (minimal fat - <5g) 33 2 scoops of protein powder mixed in with 1 serving of oatmeal 1 sliced banana 1 cup of regular or lactose free skim milk 1 serving Grow! 1 can tuna fish 1 cup of regular or lactose free skim milk 2 pieces of whole grain bread Vegetables 8 egg whites 1 scoop of protein in 1 serving of oatmeal 1 slice of whole grain bread 1 piece of fat free cheese Vegetables 2 cups of regular or lactose free skim milk 1 scoop protein 2 pieces of fruit 1 can tuna fish 1 scoop protein powder Vegetables 1 tablespoon of concentrated fish oils 2 scoops protein powder in water 1 tablespoon flax oil Here's a list of good fats and proteins for the protein plus fat meals: Fats: Concentrated fish oils (PUFA-omega 3), flaxseed oil (PUFA-omega 3 and 6), olive oil (MUFA), canola oil (MUFA and PUFA), fat from nuts (MUFA and PUFA), fat from beef and eggs, animal fat (SFA) Proteins: beef, salmon, whey, casein, turkey, whole eggs, pork Individual Differences - Are You Sensitive? Here's a list of good carbs and protein for the protein plus carbohydrate meals: Carbs: apples, oranges, oatmeal, all bran cereals, vegetables, mueslix, white pasta, flax bread, yams Protein: chicken, whey, casein, turkey, egg whites, skim milk, tuna, cottage cheese Protein plus fat meals (minimal carbs<10g) 1 can salmon 1 scoop protein powder in water Vegetables 1 tablespoon of concentrated fish oils 8-12 oz lean beef Fat free cheese 1 tablespoon of olive oil Vegetables In the last section I recommended splitting six daily meals up into about three protein and carb meals and about three protein and fat meals. This plan works well for most people in terms of maximizing muscle gain while minimizing fat gain when overfeeding. However, just like different training programs are necessary for different individuals, individual responses to nutrition are varied. So rather than telling you that there's one program for all, I hope to give you some tips so that you can determine which eating plan is best for you. The factors governing your response to different nutritional intakes are pretty diverse, but one major factor I've been focusing on lately is insulin and glucose tolerance. In my mind, insulin sensitivity seems to be the most important factor dictating how the body will handle carbs. For those who have high insulin sensitivity, the body responds to carb intake with small insulin surges. Although the insulin surges are small, the cells are very responsive to that little amount of insulin and do a great job of becoming anabolic. Since lots of insulin 34 can inhibit fat loss, the ideal scenario is to become very insulin sensitive so that only small amounts of insulin are required for anabolism and so that those small amounts of insulin don't prevent fat loss. glucometer, some glucose test strips, and a standard glucose beverage (ask your pharmacist about this because it has to be a specific kind. Pepsi won't work). Once you've got the goods, you'll plan your test. In my experience, individuals who have high insulin sensitivity maximize their muscle to fat ratio on diets that are high in carbs and lower in fat (50% carbs, 35% protein, 15% fat). Those with moderate insulin sensitivity tend to do best on diets that are more isocaloric (30% carbs, 40% protein, 30% fat). And those with poor insulin sensitivity do best on diets that are low in carbs (50% protein, 35% fat, 15% carbs). After going at least 24 hours without exercise (do this test after a day off from training), you'll wake up in the morning (fasted at least 12 hours) and you'll take a blood sample from your finger tip. Write down this number. Then drink your glucose beverage and continue to take blood samples at 15, 30, 60, 90, and 120 minutes. Record all the numbers at each time point. Here's a little chart of what you should expect: So within the framework of this article, if you're highly insulin sensitive, more than three of your daily meals would be carb plus protein meals. If your insulin sensitivity isn't so great, more than three of your meals will be protein plus fat. Normal Insulin Excellent Insulin Sensitivity and Sensitivity and Glucose Glucose Tolerance Tolerance Insulin Sensitivity - I Want Your Blood So the next question is how do you know if you're sensitive or not? Did you cry at the end of Titanic when Leonardo DiCaprio's character sank like a blue Freezer Pop into the North Atlantic? Well, there you go; you're sensitive. Me? I cried like a baby. Okay, okay, actually there are several methods. The easiest thing to do is just think about what types of diets you respond to best. If low carb diets work great for you, then you're probably insulin insensitive. If you can eat a lot of carbs and not get fat then you're probably insulin sensitive. If you'd like something more concrete than that, read on. Some experts use very simplistic recommendations for testing insulin sensitivity, methods I disagree with. For example, I've heard the statement that if you have an appleshaped physique or if you get sleepy after a carb meal then you're insulin resistant (insensitive). In my opinion, these are way too non-specific and tell you very little about your nutrient needs or if you're making progress. Instead, I prefer methods that, although more time consuming, are objective. The first is an oral glucose tolerance test. For this you need to go to your local pharmacy and purchase a Fasted Blood <100mg/dl <70mg/dl Glucose Peak Blood <180mg/dl at <130mg/dl Glucose peak Time to Maximum Blood 30-60 minutes 15-30 minutes Glucose Level Time Back to Fasted 30-60 minutes 60-90 minutes Glucose Level The second test that I like to recommend for assessing insulin sensitivity is a fasted glucose and insulin test. For this you need to see your doctor. This test is simply a blood draw in the fasted state. It's easy to do. Just schedule an appointment, the nurse will do a single blood draw, and then the lab will measure the levels of insulin and glucose in your blood at this time. Using one of the following equations, you'll have both an insulin sensitivity score and a pancreatic responsiveness score: Insulin Sensitivity = Fasted Insulin (mU/L) / 22.5 x e ^ -ln(Fasted Glucose (mmol/L)) OR 35 Fasted Insulin (pmol/L) x (Fasted Glucose (mmol/L) / 135) Pancreatic Beta Cell Function = (20 x Fasted Insulin (mU/L)) / (Fasted Glucose (mmol/L)-3.5) OR (3.33 x Fasted Insulin (pmol/L) / (Fasted Glucose (mmol/L)3.5) If you're not a math whiz or don't own a calculator, have your doctor do the math for you. Remember, you have to go to his office to get the test done in the first place. Once you have these values, compare your numbers to the following to see how sensitive you are: Insulin Sensitivity Lower score = more sensitive Normal insulin sensitivity: score should be below 2 Excellent insulin sensitivity: score will be around 0.5 Pancreatic Beta Cell Function Higher = better pancreatic function and insulin release Normal pancreatic function: score should be about 100 Excellent pancreatic function: score will be above 200 Once you've collected these measures, you'll have a better indication of what type of diet you need to consume. I recommend doing these tests at least once every few months to see how your diet and training is impacting your insulin sensitivity. Let's Get Sensitive! So let's assume that you've done the tests mentioned above and you weren't happy with the results. You're insulin insensitive and, dammit, you don't like it! Well, instead of resigning yourself to a flabby midsection for the remainder of your days there are some things you can do to increase insulin sensitivity. Both aerobic and resistance training greatly increase insulin sensitivity through a variety of mechanisms. So include both in your program. I've seen tremendous increases in insulin sensitivity with three to four intense weight training sessions per week lasting 1 to 1.5 hours per session. These sessions should be coupled with at least three or four aerobic sessions lasting 30 minutes per session. To really target insulin sensitivity, you'd want to perform weight training and cardio separately. In addition, supplements like omega 3 fatty acids, fish oils, alpha-lipoic acid, and chromium can increase insulin sensitivity. I typically recommend starting out with 600 mg of alphalipoic acid (ALA) and concentrated fish oils containing a total of six to ten grams of DHA and EPA (the most active omega 3 fats in fish oils). On the flip side, stimulants like ephedrine and caffeine can decrease insulin sensitivity due to their effects on metabolism. Furthermore, the low carb, high-fat diets that have become popular can also lead to decreased insulin sensitivity. That's why my trainees don't take stimulants or go on no-carb diets (unless they're dieting down for a show and then they'll do occasional no-carb diets every few months for a maximum of three weeks at a time). So if your insulin sensitivity isn't ideal the first time you measure it, try the approaches I listed above. Then go back after a month or two and re-test. You'll see that the numbers look much better. Individual Differences - Experimentation Even though the last section will help you better define where you stand with the insulin issue, probably the most productive way of determining which eating program is best for you is to experiment on yourself. So for eight weeks, I encourage you to follow a 50% carb, 25% protein, and 15% fat diet that exceeds your energy needs (as determined in Part I of this article). During this time, record your gains in terms of muscle mass and fat mass. This will give you a muscle:fat ratio. 36 Then go back to your normal eating for eight weeks. After those eight weeks, try a new diet of 30% carbs, 40% protein, and 30% fat for eight more weeks. Again record the muscle:fat ratio. After these 24 weeks you should know which type of diet is more effective for your body type. I know it seems like quite a bit of time to devote to figuring out your eating needs, but assuming that you've been training for years or plan to be training for years to come, 24 weeks is only a small period of time. In addition, the results of your efforts will be applicable for the rest of your life. something about it by following my suggestions above. Remember, if you aren't putting on muscle while following a good weight training program, then it's probably your diet that's to blame. With Massive Eating, your problem is solved, so no more excuses! If you ever find yourself making statements about your genetic limitations or your unreasonably fast metabolism, revisit these articles for a wake up call. "Limitations" can become challenges to work through or just weak excuses that keep you down. Now, shouldn't you go get something to eat? Remember, however, that when constructing your eating plan you must realize that just because you're following a diet with 50% carbs, 25% protein, and 15% fat or a diet 30% carbs, 40% protein, and 30% fat, that doesn't mean that each meal is made up of these proportions. In fact, the meals should not all be of these proportions because this will mean undesirable blood levels of fat, carbs, and insulin. So using the techniques I taught you during the meal combination section, design a plan that has different proportions of macronutrients during different meal times but that achieves the optimal proportions of (4030-30 or 50-25-15) by the end of the day. Summary Here's a quick and dirty summary of the Massive Eating plan: 1) Read Part I and determine your daily caloric needs. 2) Eat meals consisting of fat and protein together with very little carbs. Also eat protein and carbs together, but with very little fat in those meals. Don't eat carbs by themselves and don't eat carbs with fat. 3) Determine your macronutrient ratios based on your level of insulin sensitivity. You can do this with the tests I explained or you can just try different diets consisting of different rations of protein, carbs and fat. If you're insulin insensitive you can do 37
