Muscle doesn't turn in to fat. It is lost and then replaced with fat.

@112frankybaby you realize it doesn't work that way right? Muscle and fat are composed of TOTALLY different materials. Muscle does not magically turn into fat, that is impossible. Sure she will lose muscle mass and will become less toned and she might gain some fat, but the muscle will not become fat.

@112frankybaby Please take a biology class before posting stupid comments. Muscular catabolism doesn't convert muscle into fat, in fact that's impossible. You either lose/gain muscle, or lose/gain fat. That's it.
