It is best not to use diet pills to lose weight. All diet pills have great side effects, which are harmful to the heart and liver. My doctor friend told me this. Some people will have dizziness, diarrhea, nausea and other symptoms after taking diet pills. The best way is to control appetite and strengthen exercise. For example, it's good to take a quick walk and run for two hours after meals, and do Duoyan Zheng aerobics between work.
