Both groups lost weight. But the placebo and GC groups did not significantly differ. So basically, a little more awareness helps you lose weight, with or without garcinia cambogia.
Another study took overweight women and gave them 800mg of GC before each meal. After sixty days, there was a significant decrease of triglyceride levels in the blood of the GC group. However, body-weight and fat mass showed no significant changes.
With any of these studies, duration and sample size matter. There haven’t been any long-term studies done on a large group of people. If there is some truth to the hypothesis that Garcinia Cambogia helps people lose weight, we don’t know about it. There is not enough scientific evidence to back the claims made by the supplement makers, magazines, and celebrity doctors.
The problem with most of these kinds of products is that much of the promising results come from rat studies. It does seem that rats on garcinia cambogia do experience less fat accumulation. This reminds me of CLA, a supplement that was popular before GC and had similar fat-loss claims. It worked really well in rats. Genetically obese rats would deflate like a balloon. Human studies were not so promising. Unfortunately, rats aren’t humans and the dosages that show success in rats are often unrealistic to replicate in people.
