The problem is, our body is very smart. It won't just keep The 4 Week Diet burning the same number of calories and taking the excess from fat. Your body doesn't know that you are on a diet. It will think you're starving. To help keep you alive, it will cut way back on the number of calories that uses. To do this it will slow down your metabolic rate and will start eating away at your muscle mass – to get it's needed calories.Over a long-term, this is disastrous. Your muscles burn far more calories than your fat, so if you lose them, it not only has a bad effect on your body but it also affects your ability to keep weight off in the future. The 500 calorie diet, as one of the diets for quick weight loss – works… but only for a short term.For the vast majority of us, especially if we are carrying extra weight, eating only 500 calories per day is literally starving our bodies. Most likely, you've been taking in 2000 to 5000 (or more) calories per day and suddenly dropping to 500 will immediately move your body into starvation mode. So, your metabolism slows way down in order to conserve energy.Thankfully, the majority of us discontinue our dieting before that happens. As soon as your diet is over, and you go back to your old eating habits – like we all do – you will have a sudden gain in weight. Actually, you'll gain more weight than you would have, had you not ever gone on a diet to begin with. Diets for quick weight loss just don't work. Plus, since you have lost so much muscle mass, it makes it much harder to maintain your weight in the future.
