OBESITY AND THE PALEO DIET By Brian Kelsey The “SAD” Diet Consists primarily of: Fast Food Processed Food/Pre-prepared Meals Low Fat Meals/Snacks High Carbohydrate Processed Oils and Transfats Sugar, Sugar, Sugar This diet is literally killing us! You can thank the 80’s The 80’s brought us: Terrible music Even worse fashion (parachute pants were cool) The war on fat and cholesterol USDA creates the food pyramid Advocates decreased consumption of fat/sugar Increased consumption of carbohydrates Rise of the processed food and diet industries We are the Government, would we lie to you? The Food Pyramid It’s Offspring The Obesity Epidemic We are now the third fattest nation on earth behind Saudi Arabia and Mexico. More than one-third of U.S. adults (35.7%) are obese. Since the 1980’s, rates of obesity, diabetes and heart/cardiovascular disease have tripled. We are not only fatter, we are sicker: Estimated annual medical cost of obesity in the U.S. was $147 billion in 2008; the medical costs for people who are obese were $1,429 higher than those of normal weight The Obesity Epidemic Obesity-related conditions include: -Heart disease -Stroke -Type 2 diabetes -High blood pressure -Orthopedic problems -Sleep apnea -Depression -Kidney disease -Hyperlipidemia (High levels of fat in blood) -Certain types of cancer It’s just business, nothing personal The food industry is no different than the tobacco or fuel companies: Lobby government agencies (such as USDA and FDA) Backed by “Food Scientists” Supported by government subsidies Focused on profits despite negative health consequences to the public We are literally high on food Food acts on the reward pathway in the brain Causes release of Dopamine and Endorphins Reinforces eating behaviors Sugar has been found to more addicting than cocaine and heroin Certain grains (especially wheat) contain “morphine like” compounds Prehistoric hormones in a modern world Our sense of taste was originally designed to find nutritious foods to ensure survival. Thanks to food science, we have crap like: Transfats/Margarines Corn Syrup/High Fructose Corn Syrup Artificial Sweeteners Preservatives Variations of Salt additives Food is scientifically designed to: Taste good Cause overconsumption Increase sales I ate it so I have to burn it right? All calories are not equal. Each macronutrient (protein, fat, carbohydrate) elicits a specific hormonal response. This is the key to health! During digestion: Protein converted to amino acids Fats to fatty acids, stored as triglycerides Carbohydrates to glucose Unused glucose converted to fatty acids Hormones Involved in Diet Insulin Glucagon Leptin Cortisol Dietary hormones are either: Anabolic or Catabolic (build or breakdown) Lipogenic or Lipolytic (fat building or fat burning) Insulin-The Fat Maker Insulin is the “energy” or fat storage hormone. Anabolic, lipogenic Insulin tells the body to: Store glucose in the muscles and liver for energy Store the rest as fat Transports amino acids into muscle cells to build and repair Fiber and fat in food slow the release of insulin. Insulin Constant elevated blood levels of insulin cause: Hypertension Cardiovascular disease Coronary artery disease Obesity Chronic inflammation Diabetes Decreased testosterone production in men Insulin Glucose will always be used as fuel when insulin is present. Fat will stay Insulin resistance- cells no longer respond appropriately to insulin's signal Forces pancreas to release more insulin Insulin signal eventually is no longer recieved Leptin LeptinSatiety Hormone (fullness) Decreases lipogenesis Made and released by fat cells More fat, more leptin Tells us we have eaten enough/stored enough fat (energy needs are satisfied) High insulin levels block the leptin signal. Leptin resistance- the leptin signal no longer is properly noticed in the brain. Cortisol Cortisol- stress ( or anti-stress ) hormone Lipogenic Catabolic Released in response to physical/mental stress and inflammation Stores Fat, blocks insulin Increases : Blood pressure Heart rate Appetite Blood sugar Cortisol Chronically elevated levels of cortisol can lead to: Depression Poor sleep Fatigue Food craving (especially calorie dense salty and sweet foods) Overeating Obesity Insulin resistance Glucagon Produced and released by pancreas Released in response to low blood sugar or a high protein/low carb meal Catabolic, Lipolytic Opposes insulin Increases blood sugar Can convert amino acids into glucose for fuel High protein in diet will blunt catabolic effects Constant State of Flux Hormones follow Circadian Rhythm Searching for Homeostasis Leptin low in am, cortisol high As day progresses leptin will increase, cortisol will decrease Insulin and glucagon will fluctuate with food intake Increased insulin at night blocks growth hormone release Glycemic Index and Glycemic Load Glycemic Index: Measure of increase of blood sugar after the consumption and breakdown of carbohydrate Glycemic Load: Amount of insulin released in response to blood glucose levels Beets, rutabagas and carrots are examples of foods with a rather high glycemic index but low glycemic load You’re fat on the inside too! Visceral Fat Located around the abdomen, muscles and digestive organs Driven by elevated insulin levels Most dangerous of type of fat! Drives inflammation Insulin resistance Diabetes Cardiovascular disease When you lose weight, visceral fat is the first to go Large waist size is usually an indicator of visceral fat The Skinny on Fat Important for cellular function Great source of energy Need balance of Omega-6’s and Omega3’s Suggested ratio is 2:1 Omega 6 fats found in Processed food Vegetable/seed oils Non-pastured (grain fed) animal proteins and eggs Pastured (grass fed) animals are much lower in omega 6’s and higher in omega 3’s Too much Omega 6 causes inflammation We are getting approximately 20:1 in our diets The Hunter-Gatherer Diet The Paleo Diet consists of: Meats (preferably grassfed) Fish Seafood Fresh fruits and Vegetables Limited Nuts and Seeds Healthy Oils and Fats such as olive and coconut oil Food was limited and opportunistic The Hunter-Gatherer Diet The Paleo Diet does not include: Grains of any kind, this includes wheat, bread, pasta, rice, corn (it’s technically a grain), oats and barley Dairy which includes milk, cream, butter, cheese, yogurt and sour cream Legumes which includes beans of any kind, peas, soy, lentils and peanuts (yes they are a legume) No Alcohol, sorry No White Potatoes (sweet potatoes and yams are ok) The Benefits of a Paleo Lifestyle Burning stored fat for energy Dietary hormonal balance Balanced energy and reduced fatigue More efficient athletic performance Stable blood sugar Reduced allergies Improved sleep patterns Improved digestive health Paleo and the Auto-Immune Connection Auto-immune disease- immune system loses the capacity to discriminate our “self” from “non-self” Auto-immune diseases include: Rheumatoid arthritis Ulcerative colitis Chrons Celiac disease Multiple sclerosis Lupus Psoriasis Alzhiemers The “Leaky Gut Theory” Leaky Gut Syndrome (also called increased intestinal permeability): Damage the intestinal lining creating openings and allowing foreign substances to directly enter the blood stream Due to the ingestion and improperly digested food components most commonly found in grains, dairy and legumes. Bacteria, toxins, incompletely digested proteins and fats may "leak" out of the intestines into the blood stream. Triggers autoimmune reactions Why no Grains? GMO’s Phytates- binds to certain vitamins/minerals and inhibits there absorption Lectins- toxins developed by plants as a defense Lectins enter the blood stream and causing immune reaction and inflammation Gluten- protein found in wheat, rye and barely Improperly digested Causes gas, bloating, upset stomach Causes celiac disease Associated with other auto-immune disorders Why no Grains? High Glycemic Whole sugar Grains are converted to glucose Excess wheat bread has higher GI than table glucose stored as fat High levels of triglycerides from carbs in blood leads to: Systemic inflammation Cardiovascular disease Heart disease Why no Legumes? Legumes Similar to grains Hard to digest Cause GI distress Contain GMO’s Weren’t consumed by the paleo hunter-gatherer Saponins They also contain phytates and lectins as mentioned with grains Damaging to the intestinal lining and eventually enter the blood stream causing an immune reaction Soy is in many processed foods What about fiber? Fiber containing veggies Greens (kale, collard, turnip) Mushrooms Pumpkin Peas Peppers Spinach Sweet Potatoes Fiber containing fruit Apples Avocados Bananas Berries Kiwi Oranges Pears Prunes Why no Dairy? Full of hormones Intended to make young animals grow rapidly and strengthen their immune systems Contains lactose Especially estrogen Form of sugar Causes increased blood sugar and insulin release Lactose is digested in the gut by an enzyme called lactase Approximately 65% of the worlds population have not inherited the enzyme lactase Lactose Intolerance Why no Dairy? “What about Calcium and Vitamin D”? Milk is not a good source of vitamin D Has to be fortified Vitamin Go You D synthesized by sunlight outside! can get plenty of calcium from fresh vegetables/fruits Greens Cabbage Broccoli Spinach Carrots Artichoke Celery Pears Berries Figs Grapefruit Pineapple Banana Oranges Mango Control the inflammation Inflammation comes from stress, exercise and diet Actual cause of heart and cardiovascular disease Fish Oil-Consists of 2 very important Omega-3 fatty acids: EPA = eicosapentaenoic acid DHA = docosahexaenoic acid Reduces inflammation Improves cognitive function Recommended 1000-5000mg of high quality Omega-3 per day depending upon health needs, dietary intake or athletic regimen Sleep! (7 to 9 hours per night depending on needs) Drink plenty of H2O
