Hunger, Eating and Health

Question

How is energy stored in the human body?

Answer 1

1. Glycogen (glucose)

2. Fats

3. Proteins

Answer 2

Because it gives the highest amount of energy. It can store twice as much energy as glycogen. Also, glycogen stores substantial quantities of water, and fat doesn't. So it is much more effective.

Answer 3

1. Difference in consumption; this could differ between individuals, between cultures, and some people just have large cephalic phases.

2. Difference in energy expenditure; some people just efficiently burn more fat when they exercise.

3. Genetic differences; also differences in genetics can occur for differences in obesity. Research has shown that some genes are compatible with obesity genes.

Answer 4

Because after a weight loss program, people automatically go back to their previous habits. This can be explained by the settling point model. Permanent lifestyle changes is the best way to keep losing weight.

Exercising only account for 20% of weight loss, the rest is used to digest food etc. Our bodies are efficient machines, so only a small number of calories will be burned. Most people also think they can eat more after a heavy work-out.
