Effects of (−)-hydroxycitric acid on appetitive variables
(-)-Hydroxycitric acid ( HCA ) reportedly promotes weight loss , in part , through suppression of hunger . However , this mechanism has never been evaluated in humans in a controlled study . Eighty-nine mildly overweight females were prescribed 5020-kJ diets for 12 weeks as part of a double-blind , placebo-controlled parallel group study . Forty-two participants ingested 400-mg caplets of Garcinia cambogia 30 - 60 min prior to meals for a total dose of 2.4 g/day ( 1.2 g/day HCA ) . Forty-seven participants ingested matched placebos .  Weight and body composition were assessed at baseline and every other week for 12 weeks . Food intake and appetitive variables were assessed at baseline and monthly for 12 weeks . Both groups lost body weight with the active group achieving a significantly greater reduction ( 3 . 7+/-3.1 kg versus 2.4+/-2.9 kg ) . No effects of the HCA were observed on appetitive variables . The active treatment group did not exhibit better dietary compliance or significant correlations between appetitive variables and energy intake or weight change . This study does not support a satiety effect of HCA
