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 UK. SlimFast promotes diets and weight loss plans featuring its food products.
There is mixed evidence on the effectiveness of the diet, although it appears to function no better than behavioral counseling.
