The reason why bitter melon can lose weight is that bitter melon is found to contain high energy lipids, which is regarded as a historic breakthrough and development in weight loss research in western countries. From the bitter melon found in a special ingredient as expensive as gold: high-energy lipotropin, or RPA, this is known as the "fat killer" of the special ingredients can make the intake of fat and polysaccharide reduction of about 40-60%; Chinese Academy of Sciences, Shanghai Research Institute of the experts drew on the last two years popular in the West, has successfully attacked the bitter melon weight-loss fever, has been the first time in the past two years. Experts from the Shanghai Research Institute of the Chinese Academy of Sciences have successfully overcome the difficulties in extracting high-energy lipotropic substances by drawing on the popularity of bitter gourd in western countries in the past two years. In a set of biological extraction equipment valued at tens of millions of dollars, the bitter melon elements to maintain more than 90% of the biological activity and extraction and concentration into the S fiber elements. Pharmacological studies have confirmed that the high energy lipotropic factor does not enter the human blood, only acts on the important part of the body to absorb fat - the small intestine, by changing the intestinal cell mesh, preventing the absorption of fat, polysaccharide and other high-calorie macromolecules, thereby accelerating the absorption of small molecules of nutrients in the body, and does not participate in the metabolism of the human body, so there is no toxicity and side effects
