|Claims:||1. A method for reducing a subcutaneous fat deposit in a subject in need thereof, the method comprising administering locally to a subcutaneous fat deposit in the subject a composition comprising: a fat-dissolving effective amount of deoxycholic acid (DCA) or a salt thereof, wherein the DCA has a .sup.14C content of less than 1 ppt; a pharmaceutically acceptable excipient; and optionally a lipid. |
2. The method of claim 1, wherein the subcutaneous fat deposit is associated with a condition selected from the group consisting of obesity, fat redistribution syndrome, eyelid fat herniation, lipomas, Dercum's disease, lipodystrophy, buffalo hump lipodystrophy, dorsocervical fat, visceral adiposity, breast enlargement, hyperadiposity, diffused body fat around trunk and arms, and fat deposits associated with cellulite.
