Garcinia Cambogia has a rind that contains HCA (Hydroxcitric Acid.) The HCA is recognized as the key to Garcinia Cambogia’s effect on the fat metabolism and the absorption. HCA actually slows the uptake of glucose. Extra sugars cause the body to make extra insulin, which then results in a drop in blood sugar levels as well as more cravings for sugar. By slowing the process, you are reducing the cravings which provides an edge for you to keep a healthy diet. Having stable blood sugar also helps in the prevention of emotional eating. This is because you will feel much better throughout the day although you have eaten less calories. There has been research to show that even without extensive diet and exercise, HCA and Garcinia Cambogia help in fat metabolism.
