How to correctly understand diet pills?

In the prevention and treatment of obesity, people generally do not use drugs, because so far there is no really effective drug to treat obesity. Some doctors refuse to prescribe any medicine for patients, because taking medicine to treat obesity will arouse patients' fantasies, pin their hopes entirely on drugs and refuse to seriously change their eating habits. Some doctors advocate the use of drugs as an auxiliary measure of diet management when necessary, and only use patients' superstitious psychology about drugs to consolidate their long-term adherence to diet management. It is generally believed that when diet control and physical exercise are ineffective, drug-assisted therapy can be used. The ingredients of western medicine to lose weight are different.
