There are many ways to lose weight. Weight loss should be based on exercise and diet, not oral drugs.
Guiding opinions:
Start to develop the habit of walking, or try to do other aerobic exercises. At first, run fast every day to do aerobic exercise 15 minutes, then gradually increase the extension time every day, and finally lock in one hour to one and a half minutes of exercise every day. You must have patience and persistence to lose weight, and persistence is success.
