 It is a very good source of hydroxycitric acids (structurally related to citric acid, a sour flavorant) and one of the isomers, known as (-)-Hydroxycitric acid, is thought to help in weight control.

The mechanism of action is inhibiting an enzyme called Citric acid lysase which is required in the synthesis of fatty acids, known as de novo lipogenesis.

At least in rats, evidence of suppressed de novo lipogenesis has been noted and oral consumption of (-)-Hydroxycitric acid appears to reliably reduce food intake and body weight (the latter to a degree where food intake cannot explain all the observed effects)
