The fruit garcinia cambogia is a tropical fruit that has been utilized as a weight loss supplement. The active ingredient, hydroxycitric acid, has been purported to boost fat burning and lower appetite. AS such, it is being sold in various pharmacies and stores as a weight loss agent.
However, numerous clinical trials have been conducted showing no significant difference in weight loss in patients that have been given the supplement. These studies were conducted over limited periods of time (12 weeks) so there could be potential for greater benefit over time, but this does not appear to be a game changer supplement. One study (here) showed no significant difference in weight loss of fat accumulation in patients treated with the supplement. Another study (here) showed no significant difference in weight loss although there was some decrease in visceral fat accumulation.
