How Do Some People Seem To Eat And Never Gain Weight (PT I)

Metabolism is how your body is utilizing your food!

When there is excess food, meaning you eat too much(more food then you are expending) some people's metabolism will store it as Fat while other people will utilize the extra calories (food) for energy.

What this means is: two people can be doing the same things and eating the same foods while one person will burn more calories than the other, due to his metabolism!

This is based on each individual's genes.
