Eat regularly, rest regularly, and keep exercising. If you don't want to go out for a run or go to the gym, buy a yoga mat and stick to the next sports App. After 7 o'clock in the evening, you can keep eating nothing or snacks for the rest of the time.
If it really doesn't work, get ready to lose weight by liposuction. Liposuction is so developed now. Compared with traditional abdominoplasty, modern liposuction has too many injuries and complications. Modern liposuction technology has the advantages of less trauma, faster recovery and less pain for patients. Direct and effective, not easy to rebound, but I believe you will work hard.
Exercise doesn't necessarily make you thinner, at least it can make you feel more elegant and your skin firmer.
