(muscle, hair, organs)
Is found in all the cells
of the body

Body Types and Obesity
Obesity is an eating disorder caused by an
imbalance of energy intake & energy output.
Causes:
1. Genetics- it may come from your family genes
2. Over-eating- can cause an increased number of fat cells before 12 yrs old. Fat cells can grow 150% their original size
3. Metabolism-obese people have a higher BMR.
Health Risks
1. Diabetes
2. Hypertension
3. Arteriosclerosis
4. Angina pectoris
5. Varicose disease
6. Kidney disease
The body types are:
Ectomorph-tall, thin, and low body fat
Mesomorph-broad shoulders, lean and muscular
Endomorph-short and high body fat
Calories
Basal Metabolic Rate(BMR):
BMR is the rate at which our bodies use energy
1. Body Composition
2. Age
3. Growth
4. Height
5. Sleep
Daily Caloric needs influence by:
1. Gender
2. Body Size
3. Genetics
4. Age
5. Physical Activity Level
Energy Equation Balance
Energy in= Energy out, weight is maintain/stays the same
Energy in is greater/energy out, weight is gained
Energy out is greater/energy in, weight is lost
Calories are the measurement
of energy found in food
-1 gram of carbohydrates has 4 calories
-1 gram of fat has 9 calories
-1 gram of protein has 4 calories

Vitamins
Gets absorbed by the
small intestine, then
stored in the liver. i.e
vitamin D
Water-Soluble
Vitamins
The body cannot store
these, so you eat them
from other foods. i.e vitamin C
Chemicals the body uses to build energy
from foods
Builds and maintains cells
Minerals
Electrolytes
Balance fluids and
conducts nerve impulses
Helps get energy
from macronutrients
