Slim Fast

SlimFast is an American company headquartered in Palm Beach Gardens, Florida that markets an eponymous brand of shakes, bars, snacks, packaged meals, and other dietary supplement foods sold in the U.S., Canada, France, Germany, Iceland, Ireland, Latin America, and the U.K. SlimFast promotes diets and weight loss plans featuring its food products. There is a lack of high quality evidence on the effectiveness of the diet, although it appears to function no better than behavioral counseling. from Wikipedia
