p. 220 -223
Why You Eat
3 reasons
1. To meet your body’s
nutritional need
2. To satisfy your
appetite
3. To supply your body
with energy
Hunger vs. Appetite
HUNGER- A FEELING OF PHYSICAL
DISCOMFORT THAT IS CAUSED BY YOUR
BODY’S NEED FOR NUTRIENTS
APPETITE- IS A DESIRE FOR FOOD THAT IS
BASED ON EMOTIONS AND OTHER FACTORS
RATHER THAN
Basal Metabolic Rate (BMR) & Thermo-genesis
BMR
BMR is the rate at which you
use energy when your body is at
rest.
Thermo-genesis
(Thermo= heat)
(genesis= creation)
Which is a rise in your
body temperature and a
temporary way to increase
the rate at which our body
burn calories.
How does exercise increase my BMR?
Only regular and consistent exercise over time converts fat to muscle. Muscle
burns more calories to stay alive, that's what speeds up your basal metabolic rate
so that even your basic bodily functions utilize more energy.
