How does exercise help you lose weight?

Answer 1

In order for the body (or anything, for that matter) to move, energy is required. The body produces energy by "burning" fuel.

When the body takes in food, it either uses it right away or stores this in a number of ways until it can be used. The most long-term of these ways in in fat. The body will first burn the most available chemicals - the food that has not yet been stored long term in the form of fat or protein..

When this temporarily stored energy is gone, though, the body is forced to use a different form of energy - this energy is found by burning fat or protein.

It's for this reason that when one is trying to lose weight, it's suggested that he be on a low-calorie diet, so that the body starts to use the stored energy in fats to burn for calories to do the work of exercise.
