In terms of diet, it's ok. Be careful not to eat too much. Don't eat fried, pickled, too sweet or too salty food. Be sure to eat more fruits and vegetables. Don't sit or lie prone for half an hour after dinner. It is best to stand all the time. If you find it difficult to kill time, you can choose to wash dishes or tidy up. This will not only reduce the accumulation of fat, but also help you digest. Because 30 minutes after a meal, if you keep a motionless posture, it is most likely to form abdominal fat.
If you pay attention to the above two points, I believe it will have an effect in another month.
