However, what works in rats doesnt always work in humans.
Bottom Line: Studies in rats show that the active ingredient in Garcinia Cambogia can inhibit a fat producing enzyme called Citrate Lyase and increase serotonin levels, leading to significant weight loss. A Look at Some Human Studies Fortunately, I also found several human studies on Garcinia Cambogia. All of these studies are so-called randomized controlled trials, which are the gold standard of scientific experiments in humans.
The biggest of the studies included 135 overweight individuals, which were split into two groups (7): Treatment group: 1 gram of Garcinia Cambogia Extract, 3 times per day, taken 30 minutes before meals. Placebo group: The other group took dummy pills (placebo). Both groups also went on a high-fiber, low calorie diet.
