Diet pills have a certain effect on obese patients who are extremely obese, but if ordinary people rely on diet pills to help them lose weight for a long time, they are likely to become dependent and even have side effects on their bodies. The weight-loss drugs sold in the market usually contain orlistat or L-carnitine, which can effectively help patients lose weight, but only apply to obesity caused by endocrine disorders. Other weight-loss drugs on the market are probably hormonal drugs, which are harmful to weight-loss people and are likely to rebound immediately after stopping taking drugs. So pay attention to the ingredients of diet pills. Diet pills containing orlistat and L-carnitine are generally effective, while other hormone diet pills are not only ineffective but also harmful to human body.
