Synthetic chemicals designed to stop the fat in food from being absorbed. Manufacturers claim that fat blockers provide an easy and quick slimming aid, and that users can eat fatty foods without putting on weight. Unfortunately, fat that is not absorbed may accumulate in the lower bowel where it can cause incontinence by reducing anal sphincter control. In addition, the stools will be smelly, fatty, and foamy. Fat blockers are being used experimentally in the USA but have not yet received approval for general use in Britain. Before approval, the authorities must be certain that fat blockers do not interfere with the absorption of fat-soluble vitamins and essential fatty acids.
