Makes Sense!

If you begin eating 2,500 calories per day then your metabolism will adjust itself so that your body begins burning 2,500 calories per day. If you try to starve yourself by suddenly eating 1,000 calories per day then your metabolism will again ADJUST ITSELF so that your body begins to burn only 1,000 calories per day. That's why you have failed in your past dieting attempts, that's why you always seem to fail when you try and starve yourself.
