Exercise cuts weight re-gain in three ways - study

University of Colorado at Denver researchers have found that exercise minimizes weight re-gain after dieting by curbing appetite, burning fat and lowering what scientists call the "defended" weight.

The study found that exercise causes the body to burn fat before it burns carbohydrates. Because the carbohydrates are still available to be burned for energy, the body is slower to trigger pangs of hunger.

Researchers also discovered that exercise prevents an increase in the number of fat cells during weight gain, which challenges the belief that the number of fat cells are fixed in number.

The "defended" weight is each individual's "natural" weight, which the body constantly strives to achieve. Exercise lowers that weight, so the body tries to stay slimmer than it otherwise might.

The Spartan Diet perspective is that everyone should exercise every day. Nobody should go on a temporary diet, but instead permanently embrace the diet that leads to total fitness.
