Even after dieting and exercise, there are people who do not lose weight. Why? They have a problem called metabolic syndrome X. That means basically your body store all the food you eat into fat thus saving it for famine days. Check your neck and see if you have a mark like you have burnt your neck with a hot ornament (chain) and black knuckles. Check your insulin level. Chances are your body is producing more insulin. Those who suffer do have hunger pangs andf may get head ache if they don't eat! Like to hear about it from people experiencing this problem.
