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.
A review posted to the Journal of Obesity compiled the results of nine different studies using garcinia for weight loss in humans. The findings confirmed mixed results of the supplement, with some studies producing significant results and others showing little difference.
The average reduction in body weight was small, as the studies were only done for short periods of time. A study posted to Critical Reviews in Food Science and Nutrition pointed out how short most of the studies into garcinia cambogia were. Studies in humans have been done on a small number of people for a short amount of time. Longer tests need to be carried out on bigger groups of people to understand the safety and effectiveness of garcinia or HCA fully.
Garcinia cambogia has been used for centuries. The fruit is safe to eat, and the supplements have helped many people lose weight. However, clinical evidence of its efficacy is mixed at this point. If a person is considering taking garcinia cambogia as a supplement, they should research it well and discuss it with a doctor before starting. Weight loss miracle pills often sell a future that does not exist. Maintaining a healthful diet and taking regular exercise are still two of the best ways to improve body weight. Supplements may help these efforts, but nothing will replace these important staples in a healthy lifestyle.
