Garcinia cambogia might help to aid in weight loss, according to WebMD. A common school of thought is that the hydroxycitric acid in the natural herbal substance reduces the appetite and stops the ability of the body to make fat.
The weight loss on this herb is negligible, states WebMD. In one study, the weight loss difference in people who took the supplement and people who didn't was only 2 pounds. With that small of a difference, the increased weight loss might be because people in the study followed an exercise regime and a low-calorie diet, not because of the supplement.
