The effect is still good. Let me tell you this slimming principle. Riley is a long-acting and powerful pancreatic inhibitor of specific gastrointestinal lipase. It forms valence bonds with the active serine sites of gastric lipase in the stomach and pancreatic lipase in the small intestine cavity, and binds with lipase to inactivate lipase, thus playing a therapeutic role. Inactivated enzymes can not hydrolyze fats (mainly triglycerides) in food into absorbable free fatty acids and monoglycerides, and cannot be absorbed by human body without decomposition. 30% of the fat in food can't be decomposed, undigested triglycerides can't be absorbed, and they are directly excreted with defecation in the form of original macromolecules, thus reducing calorie intake. It is necessary to decompose their own fat to obtain energy in order to achieve the final effect.
