I personally would advise against weight loss pills as they change your body chemistry and filter fat in a way that the body was not designed to do so. BUT thats just my opinion. i know on alli your supposed to eat nothing over 5g fat to stop the dredded side effects, so you would be on a diet anyway. i think theyre supposed to help lose 1lb for every 4lbs you lose yourself or something. but for me the freedom of choice while loosing weight is much more important!
