The main effective component of Garcinia Garcinia is hydroxycitric acid in the peel, and the main function of hydroxycitric acid is to hinder the synthesis of fat. When people ingest sugar, these sugars are broken down into glucose, transported to muscles and converted into heat. But if the calorie intake is greater than the consumption, the excess glucose will be converted into fat and stored, which is the reason for obesity.
If Garcinia cambogia fruit is ingested before meals, it can prevent glucose from being converted into fat and promote it to be converted into liver sugar which is easy to be used as heat, so it can prevent obesity.
