Garcina Cambogia is a plant. Once it is turned into a supplement, it cannot be regulated by the FDA. This particular supplement has not been proven effective in the treatment of lowering cholesterol. It may not harm you, but it also may not aid you in lowering your cholesterol. As far as the lap band surgery, that will promote weight loss alone. This procedure is designed to make it hard for you to eat large amounts of food at once. As you are forced to eat less, your cholesterol may decrease. However, the best way to lower your cholesterol is to eat a healthy diet. This includes eating mostly whole grains, choosing foods low in saturated fat, and eating fresh fruits and vegetables.
