A low fat diet is also a low calorie diet, usually very low in protein. When a person follows a diet like this (Weight Watchers, Jenny Craig, Nutri-Systems, etc.) their bodies are deprived of calories. Your body’s metabolism requires a certain amount of calories to perform at optimal performance. When you deprive your body of adequate calories, it finds alternative fuel sources and slows itself down. What most people don’t realize, is that your body doesn’t burn stored body fat as an alternate fuel, but rather burns muscle. Your body will save its stored fat. By consuming muscle, your body does two things. First, it uses the muscle for immediate fuel, and secondly, it slows your metabolism. Ask yourself one question- did they check your body fat? If the answer is no, how do they expect to know whether or not you lost muscle?
