Metabolism
 Definition of Metabolism:
The total amount of calories
burned in the body to sustain life.
You can also think of it asenergy that your body uses to
stay alive.
9
Metabolism
Factors That Affect MetabolismThere are many different things that
can cause the metabolism to speed up
or slow down.
1. Age- as one get older metabolism
slows down.
2. Body type- those with more lean
muscle mass have a higher
metabolism.
10
Metabolism
3. Fasting or starvationlowers the metabolism.
4. Exercise- the more physical
activity you do the higher your
metabolism is.
5. 5-6 small meals a dayincreases your metabolism.

Carbohydrates.
Protein.
Fat.
Vitamins
Minerals
Water
18
Carbohydrates
 Definition- the starches and sugars
present in food.
Carbs are the preferred source of
energy, which means the body
will try and use this nutrient first
to produce energy.
19
Carbohydrates
 Carbs provide 4 calories per gram.
 Ex. If an apple has 15g of carbs
then it has 60 calories from
carbohydrates.
 Depending on their make upCarbohydrates are classified as
either Simple or Complex.
20
Simple Carbohydrates
 This is a type of sugar that is added to many food
products like: pop, candy, cookies, cake,
doughnuts, and any kind of snack food.
 These are the carbohydrates that we do not
want to eat too much off!!!
21
Complex Carbohydrates
 Found in whole grains, seeds, nuts,
beans and potatoes.
 The body must break down complex
carbohydrates into simple
carbohydrates before it can use them
for energy.
 These are the Carbohydrates that we
Do Want to eat, they are very healthy
for us!!!
22
Carbohydrates
 The Structure of Simple & Complex
Carbohydrates.
23
Carbohydrates
 Role of Carbohydrates:
 Your body converts all carbohydrates
to Glucose (which is a simple sugar
that is the body’s main source of
energy).
 Glucose that is not used right away is
stored in the liver & muscles as
Glycogen.
 When more energy is needed Glycogen is
converted back to Glucose.
24
Carbohydrates
 Role of Carbohydrates:
It is possible to eat more
carbohydrates than you need or
you can store.
When this happens your body
converts and stores the excess
carbohydrates as body fat.
25
Carbohydrates
 Demonstration
“CHO, its use and storage in
the body”
 Glucose
Glycogen
Fat
26
Daily Review
 How many calories are in 1 gram of Carbs?
4cal/g
 What’s the difference between simple & complex carbs?
complex carbs are better for you because they provide
sustained,
long-lasting energy
 What does the body convert carbs into?
Glucose
 If you do not burn the glucose, what does it convert to and where is it stored?
Glycogen, liver and muscles
 Can glycogen be converted back to glucose and burned?
Yes
 If the glycogen is not burned, what is it convert to and stored as?
Fat
 What’s the definition of a calorie?
 What does metabolism do?
 What body type has a high % bodyfat and finds it hard to lose weight?

Fiber
 Fiber??? That sounds boring…isn’t that what
old people eat?
 Actually…Fiber is Extremely Important!
 It can help a person with constipation, it will
also reduce your risk of heart disease and can
help a person control their diabetes.
30
Fiber
 Fiber is found in many complex
carbohydrates.
 Such as: whole fruit & vegetables,
popcorn, nuts, whole wheat bread,
brown rice, whole grain cereal, etc.
 You should get at least 25-30 grams
of fiber a day.
31
Protein
Proteins are essential to building muscle.
 Proteins are made up of 20 Amino
Acids.
 Your body can make 11 Amino Acids.
 The other 9 that your body cannot make
are called essential amino acids, which
you must get from foods that we eat.
32
Protein
 Complete
Protein:
 Contain all 9
essential amino
acids.
 Comes from an
animal source.
33
Protein
 Incomplete
Protein:
 Lack 1 or more of
the essential
amino acids.
 Come from foods
of non animal
origin.
34
Protein
 Eating a combination of incomplete
proteins, for ex. Rice & Beans =
a complete protein!!!
Brown Rice
Kidney Beans
35
Protein
 Although Protein is not the major
source of energy for the body, it does
provide 4 calories per gram.
 Consuming too much protein or too
little can be dangerous to your health.
Ex. Excess body fat, Kidney &
Liver Problems.

Fat
Fats or LipidsAre a fatty substance that
does not dissolve in water.
Fats provide 9 calories per
gram.
40
Fat
That’s more than twice the
calories of carbs or protein.
We classify fats in two groups:
1. Saturated Fats
2. Unsaturated Fats
41
Saturated Fats
 All fats contain
hydrogen atoms.
 Saturated Fats hold
all the hydrogen
atoms it can.
 Saturated Fats are
also solid at room
temp.
42
Unsaturated Fats
 Unsaturated Fats are
missing some hydrogen
atoms.
 Unsaturated Fats are
liquids at room temp.
 This fat has been
associated with a reduced
risk of heart disease.
43
Saturated Fats
1. Beef
2. Pork
3. Egg Yolks
4. Cheese
5. Butter
6. Palm Oil
7. Coconut Oil
8. All Fried
Foods
44
Unsaturated Fats
5. Peanuts/Butter
1. Olive Oil
2. Canola Oil 6. Walnuts
3. Soybean Oil 7. Almonds
4. Corn Oil
45
Role Of Fat
 Fat has a great amount of stored energy.
 It also has other purposes such as:
 1. Transports vitamins A,D,E,K in your
blood.
 2. Improves growth & healthy skin.
 3. Adds flavor to food and satisfies
hunger.
46
Cholesterol
 Although fat does a number of good things for us, it
also can hurt us.
 Cholesterol Is a waxy substance that
circulates in our blood.
 Your body uses only a small
amount of it for important
functions, the rest is dumped
off to your arteries.
47
 Which increases the risk of heart disease.
Cholesterol

many vital body processes,
including the digestion, absorption,
and metabolism of other nutrients.
51
Vitamins
 Water Soluble:
 B Complex
C
Fat Soluble:
A, D, E, K

breakfast improves: mental &
physical performance while
reducing fatigue later in the
day. Finally it jump starts
your metabolism.
68
Healthy Eating Patterns

 Good Luck!
75
Maintaining a Healthy Weight/Body
Fat %
 Body Image: the way you see your
body.
It can be affected by media images
(TV, Magazines, Music, Movies,
Internet), and also by your family
and friends.
76
The Weight/Body Fat
-Calorie Connection
 Tipping the balance of the energy equation
will result in weight loss or weight gain.
 If you take in fewer calories than you burn,
you lose weight.
 If you take in more calories than you burn,
you gain weight.
77
The Weight/Body Fat-Calorie Connection
 Eating 500 fewer calories per day than
you need to maintain your weight will
result in the loss of 1 LB of body fat after
one week. (500 calories X 7 days= 3,500
calories)
 Burning an additional 500 calories per
day through physical activity instead of
eating fewer calories would result in the
same weight loss.
78
Health Risks
 Being Overweight or Having a High % of Body
Fat is a serious problem and could cause health
problems.
1. Excess body fat forces the heart
and lungs to work harder and
increases the risk of high blood
pressure and high blood cholesterol.
2. It can also increase the risk of
type 2 diabetes, asthma, and some
cancers.
79
Healthy Weight/Body Fat Loss
Strategies
 To prevent these health risks from
happening be sure to:
 1. Get at least 30-60 min of anaerobic or
aerobic activity 3-5 days/wk.
 2. Strength Train 2-4 days/wk(the more
muscle you have the more fat you burn)
 3. Eat 5-6 balanced meals (including
snacks)
80
Healthy Weight/Body Fat Loss
Strategies
 4. Drink Plenty of Water
(64 oz/ 8 glasses a day)
 5. Eat a variety of low-calorie, nutrient
dense foods (whole grain products,
vegetables and fruits).
 6. Stay away from the Pop, Candy,
Chips and Fast Food!!!
81
Healthy Weight Gain Strategies
 1. Increase your calorie intake- choose
foods high in complex carbohydrates, such
as breads, pasta, and potatoes. Also include
foods high in protein, such as chicken,
turkey, fish, beef and eggs.
 2. Eat often and take second helpingschoose more than the minimum number of
serving from each food group in the food
guide pyramid.
82
Healthy Weight Gain Strategies
 3. Eat nutritious snacks- snack
two to three hours before meals to
avoid spoiling your appetite.
 4. Build Muscle- Strength Train.

Fad Diets & Eating Disorders
 If you see an ad like
the one shown here,
think twice.
 Such ads are often for
fad diets: weight-loss
plans that are popular
for only a short time.
86
Fad Diets & Eating Disorders
 These diets are often hard
to stick with because they
limit food variety.
 Some fad diets are costly
because they require
dieters to buy certain
products.
 Fad diets that severely
restrict the foods a dieter
eats fail to provide the
body with the nutrients it
needs to be healthy and
grow.
87
Fad Diets & Eating Disorders
 Diet Pills- many diet pills work
by suppressing appetite.
 They may cause drowsiness,
anxiety, racing heart rate, or
other serious side effects, even
death!!!
 Once you stop taking the
pills, your body cannot boost
it’s own metabolism
anymore, it has to rely on the
pill!! You don’t want that!!
88
Fad Diets & Eating Disorders
 You don’t need any special diets, or
pills to help you lose weight/body fat
and gain muscle.
 All you need to do is eat right, strength
train, exercise and make sure you get
enough sleep.
 There is no magic pill or diet, hard
work and determination will lead you
to your goals!
89
Daily Review
 Why don’t diets work long-term?
 Because they aren’t supposed to! Restrict food, lose
muscle, lower metabolism, gain more weight back

per workout
 Supplementation:
spending $150-$500
a month on body
building
supplements.
101
ADONIS COMPLEX
Steroid Abuse:
 Injecting anabolic
steroids for bigger
muscles
