Abstract
Abstract A novel fructose analog is disclosed which has been found to modify the food intake of mammals. If administered during the diurnal fasting period, the mammals increase their food intakes. If administered during the diurnal feeding period, food intake is decreased. The compound is 2,5-anhydro-1,6-dihalo-1,6-dideoxy-D-mannitol, preferably 2,5-anhydro-1,6-dichloro-dideoxy-D-mannitol ("Charmitol").
