The tropical fruit called Garcinia Cambogia is a very popular weight loss supplement and could be especially useful for people who suffer from diabetes. It has the ability to suppress the appetite as well as slow down your body’s ability to make fat. The active ingredient in Garcinia Cambogia, hydroxycitric acid, blocks the enzyme citrate lyase which your body uses to make fat. It may also raise the amount of the chemical serotonin in the brain, making you feel less hungry. Some studies show that Garcinia Cambogia could lower cholesterol and triglycerides.
