fat substitute, substance used to replace dietary fat in the manufacture of foods. Fat substitutes are made in a variety of ways, mostly by manipulating natural food products such as egg whites, whey, and oats. Fat substitutes try to mimic the texture and flavor of fat while providing fewer calories and less metabolizable fat. The dietary consequences of consuming fat substitutes are under scrutiny.
