Exercise: Run at home after dinner (8-9 o'clock) in the evening. You can run while watching TV, otherwise you can't stand it. Wear running shoes and pay attention to safety. Running in the same place for a long time is easy to cramp. Keep running until you sweat, about half an hour to 1 hour, at least half an hour, the longer the better, less than half an hour has no effect.
Do the above two things well and you will lose half a catty every day.
