FOOD CONSUMPTIONS
Why do you eat?
 Psychological
a) Appetite is a desire, rather than a need, to eat certain
types of food.
b) Loneliness/Boredom
etc…
 Physical – Hunger
 Hunger is the body’s physical response to the need
for food
The amount and type of food you eat depend on many factors,
including:
• The smell and taste of food
• Mood
• Family, ethnic, and religious traditions
• Social occasions
• Health concerns
• Advertising
• Cost and availability
METABOLISM
 Metabolism converts the fuel in the food we eat into
the energy needed to power everything we do.
 From moving to thinking to growing.
 The means by which the body releases the energy in food
and uses it to build and repair body tissue.
 Just as a car stores gas in the gas tank until it is needed to fuel
the engine, the body stores calories - primarily as fat.
If you overfill a car's gas tank, it spills over onto the
pavement. Likewise, if a person eats too many calories,
they "spill over" in the form of excess fat on the
body.
 The number of calories a person burns in a day is affected by
1) How much that person exercises, 2) The amount of fat
and muscle in his or her body, and 3) The person's Basal
Metabolic Rate (BMR).
BASAL METABOLIC RATE
 Basal Metabolic Rate, or BMR, is a measure of the rate at
which a person's body "burns" energy, in the form of
calories, while at rest.
 BMR is the minimal amount of calories the body
needs to survive.
 The BMR can play a role in a person's tendency to gain
weight.
FACTORS INFLUENCING BMR
 To a certain extent, a person's basal metabolic rate is
inherited
 Exercising more will not only cause a person to burn more
calories directly from the extra activity itself, but becoming
more physically fit will increase BMR as well.
 People with more muscle and less fat generally have higher
BMRs.

Variety, Moderation and Balance
VARIETY, MODERATION, AND BALANCE are the
foundation of a healthful eating plan.
Breakfast is your most important meal of the day. Eating
breakfast is liked with better mental and physical
performance.
After 10-14 hours without fuel, your body needs to be
recharged.
Breakfast is a good time to get calcium rich foods.
BASAL METABOLISM
The amount of energy
needed by the body when it
is at rest to carry out basic
life functions.
Food Provides Energy
The amount of energy in food depends on the amount of
carbohydrates, fats, and proteins.
Extra food energy that you do not use immediately is stored
as glycogen or fat.
Breakfast provides you with important energy for activating
your body and brain at the start of the day.
Basal Metabolic Rate
Your basal metabolic rate (BMR) is the amount of energy
your body uses for basic functions.
BMR varies from person to person, depending on age,
weight, sex, and how active the person is.
Balancing Energy
You are in energy balance when the food energy you take in
equals the energy you use.
Extra food energy increases the body’s fat and causes weight
gain.
Some body fat is essential for health.
Overweight people are too heavy for their height. The extra
weight is usually due to excess body fat.
Being overweight increases the risk of many longterm health problems, including:
• Heart disease and high blood pressure
• Prostate, colon, and breast cancer
• Type 2 diabetes
• Sleeping problems such as sleep apnea
Obesity
Obesity is a condition in which there is an excess of body fat
for one’s weight.
More Americans are obese now than ever before.
Americans today exercise less and eat more foods high in
sugar and fat than in the past.
Exercise and a healthy diet can help most people stay in a
healthy weight range.
