Garcinia cambogia

If you check the labels on popular weight loss supplements, you'll find that an ingredient common to many of them is garcinia cambogia extract. The bitter fruit has been used for centuries in southeastern Asia to aid satiety to meals. Some evidence suggests that Garcinia cambogia may inhibit fat production, but the active substance in the fruit -- hydroxycitric acid.Hydroxycitric acid -- HCA -- may do what its proponents claim it will: Prevent food from being stored as fat. Dónal O Mathúna, a senior lecturer at the Dublin City University, says animal tests conducted since the 1960s show that HCA inhibits a fat-producing enzyme in your body and also helps suppress appetite.
