Recently, Dr. Oz recommended garcinia cambogia as an aid for weight loss. Garcinia is a fruit also known as tamarind. Dr. Oz reports that garcinia has traditionally been used by Malaysians to lower appetite.According to Dr. Oz, people taking garcinia were able to to lose an average of 4 pounds per month with weight loss and dieting. He also says that hydroxycitric acid (HCA), the active ingredient in garcinia, can increase weight loss in dieters by 2-3 times greater than placebo.
Dr. Oz says that some researchers have found that hydroxycitric acid can increase serotonin levels, which he says may help with mood, sleep, and lowering appetite.
HCA inhibits an enzyme that takes carbohydrates and makes fat out of them. Blocking this enzyme also reduces cholesterol production.
