What are the benefits of Garcinia cambogia?

Garcinia cambogia is a small, pumpkin-shaped, yellow or greenish fruit. The fruit is so sour that it is generally not eaten fresh but rather used in cooking. Garcinia cambogia supplements are made from extracts of the fruit's peel. The peel of the fruit contains high amounts of hydroxycitric acid (HCA), an active substance that has been shown to have some weight loss properties.
