Studies of twins and adopted children showed that overweight is at least in part an inherited trait.

Genes influence body weight. Ex: some people have more fat cells and larger fat cells than others

Individuals have different resting metabolic rates

The Physiology of Obesity

The Physiology of Obesity• Environmental factors, such as frequently eating high

calorie foods and living a sedentary life can cause obesity

• However, genes mostly determine why one man is heavier than another, but environment mostly determines why the same man is heavier than his grandfather was at same age

Aerobic ExerciseAerobic Exercise is sustained exercise that increases heart

and lung fitness.

What are the advantages of aerobics?

• Exercise reduces depression and anxiety and is a useful adjunct to antidepressant drugs and psychotherapy.

• Increase warmth ,body arousal ,muscle relaxation and sounder sleep

• Strengthens the heart, increases blood flow, keeps vessels open and lower blood pressure reaction to stress

• Occasional exercise reduced the risk of death by 29% and daily conditioning exercise reduced death risk by 43%!!

• Moderate exercise adds two years to your expected life!

Why ??• According to the genius scientists, exerci

se will orders up mood-boosting chemicals from our body’s internal pharmacy.

• It modest enhances cognitive abilities such as memory.

• It also promotes the growth of new brain cells in mice that exercise daily on running-wheel regimen.

• A system for electronically recording, amplifying, and feeding back information regarding a subtle physiological state, such as blood pressure or muscle tension.

• Allows one to gain information about their bodily responses.• E.g. Headaches (frowning) • The patients can use the information to try to command some physical responses.•As time passes, researchers believe less in Biofeedback.
