I had gastro bypass years ago and gain back some weight. can i take garcinia cambogia. i wnt to lose the rest of 40 pounds. please help?

Doubt it will work: Garcinia cambogia is a plant often used in asian recipes. The skin of the fruit contains hydroxycitric acid which is the active ingredient that in rats inhibits a fat producing enzyme called citrate lyase that increases serotonin levels leading to significant weight loss. In human studies short-term weight loss is less impressive & the clinical relevance is uncertain & statistically insignificant.
