If I’ve said it once I’ve said it a hundred times, if you want to lose weight and keep it off you need to make a life style change, because if you don’t any weight you lose will more than likely be temporary. If you are worried about hunger pangs, they reckon that the drug phenphedrine is supposed to target the hunger cravings. While this may help I still feel that a person who really wants to lose weight should also incorporate an exercise regime and eat healthy foods. Personally I prefer weight training as I feel the gain in muscle mass increases your metabolism which in turn helps to burn fat.
