Weight Loss

Diets make you fat! Calorie restriction results in muscle loss which slows your metabolism.

The more muscle you have, the faster your metabolism. You need to eat more calories to maintain your muscles. Muscle mass dictates metabolism.
When you diet, much of the weight you lose is actually lost muscle, not fat.
When you stop dieting, with less muscle and a slower metabolism, you will probably (97%) gain the weight back as fat. You are now worse off than you were before the diet.

The worst thing you can do to manage your weight is to diet. You're not overweight because you failed dieting, but because the diet failed you.
