Garcinia Cambogia Extract
In recent years, Garcinia cambogia has been promoted for weight loss due to various possible effects it may have on the body. First, it is believed to interfere with an enzyme needed to store fat, possibly causing more fat from foods to be eliminated from the body. In addition, Garcinia cambogia may cause the body to use existing fat stores for energy during prolonged exercise. Ordinarily, carbohydrates are used before fats during exercise. In animal studies, hydroxycitric acid (HCA), a major component of Garcinia cambogia, also seemed to reduce appetite by raising the amount of serotonin in the body. Serotonin is a neurotransmitter (a chemical that carries messages from nerve cells to other cells) that is thought to affect appetite control. In clinical studies of humans, however, individuals who took Garcinia cambogia while following a weight-reduction diet lost no more weight, on average, than members of a control group who followed the same diet without taking a supplement. Other human studies have had mixed results on appetite reduction; some showed little or no effect, while others reported a 15% to 30% decrease in food intake. More studies are needed to prove or disprove the effectiveness of Garcinia cambogia in weight control. In unrelated studies, Garcinia cambogia has appeared to prevent the development of stomach ulcers in laboratory animals exposed to alcohol. Although the exact process is still unclear, the HCA in Garcinia cambogia is believed to reduce the production of stomach acid. Excess amounts of stomach acid may contribute to the development of stomach ulcers. Garcinia cambogia may also enhance the ability of the stomach lining to resist damage. No human studies have been performed to confirm this effect.
