From wikipedia: Hydroxycitric acid (HCA), a citric acid byproduct, is the main active ingredient in Garcinia cambogia extract. HCA blocks fat by inhibiting the efforts of citrate lyase, an important metabolic enzyme. This is one of the reasons that Garcinia is so successful as a weight loss supplement.
Basically HCA blocks fat production in the liver and suppresses appetite. It also acts on the serotonin in your body. When your serotonin is at optimal levels you have a better sense of well-being therefore you are less likely to emotionally overeat or associate eating with feeling good. Serotonin also tends to improve your quality of sleep, which in turn helps improve your general mood.
- Appetite suppressant without giving you the jitters
- Controls sugar cravings by increasing the uptake of serotonin
- Blocks fat production by positively changing the way liver converts the sugars you consume in virtually all foods. Yes, even the healthy vegetables, fruits, and dairies contain sugar that could be converted to fat, but the HCA prevents that from happening.
- Improved sleep quality with the increased effectiveness of the natural serotonin in your body.
