In 2004 and 2005, the U.S. National Library of Medicine published two randomized, double blind, placebo-controlled studies that evaluated the impact and safety of Garcinia Cambogia extract (60% HCA). Over 8 weeks, participants lost an average of 5.4% of their body weight and body mass index (BMI) using the exact same recommended dosage of Garcinia Cambogia Extract. What's more, food intake, total cholesterol, LDL (bad cholesterol), triglycerides, and serum leptin levels were all significantly reduced, while HDL (good cholesterol), serotonin levels, and fat oxidation (fat burning) significantly increased - all without any negative side effects
