They should not be on that stuff - even w/quick results. My daughter in law used that stuff and it messed up her system big time. She got the pills online from Mexico. They are merely amphetamines - uppers.
As OUTLAW said> EXERCISE AND EATING PROPERLY is the answer for keeping it off!! The other ways are quick fixes and most people rebound gaining the weight back.
Sure the other way is slower, but healthier and you make life changes while doing it.
Also, it's not good to skip meals or "starve" yourself. Makes the body hold on to the fat for self preservation. My daughter was anorexic when a teen (coming out of the WT org. fallout) and had gained a lot of weight which she is now successfully losing by speed walking which she worked up to and carefully planning her meals. Also lifting weights to build back muscle tone.
