Garcinia cambogia is primarily marketed as a way to lose weight naturally with little to no additional effort. Some companies claim the supplement can help people lose weight without additional exercise or dieting.
It is true that the HCA in garcinia has been found to boost the fat-burning potential of the body.
One review posted to Evidence-Based Complementary and Alternative Medicine showed that garcinia did promote weight loss in many cases. But results vary widely.
Some studies using HCA have produced amazing weight loss results, while others showed the supplement had little to no effect.
Researchers note that the majority of the studies done on garcinia or HCA used animal models. The little research that has been done on humans has found that the effects of the fruit are too widespread to call beneficial. It may work, and it may not.
