When HCA inhibits citrate lyase, the fat-making process is halted and the production of LDL (bad cholesterol) and triglycerides decrease. Garcinia cambogia may help increase energy levels. Garcinia cambogia is said to deflect calorie intake away from the production of fats to glycogen, thus boosting energy.Extracts from garcinia cambogia are believed to enhance mucosal defense means in the stomach.
