Hydroxycitric Acid Diet Supplements:
Appetite & Weight Loss Trial
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.
