Try not to eat greasy food.
Eat more fresh fruits and vegetables.
Especially crude fiber vegetables, such as leeks, celery, grapefruit, bananas and so on.
Helps to expel toxins from the body and feces accumulated in the lower abdomen.
Massage the lower abdomen clockwise before going to bed at night.
If you can cooperate with sit-ups, the effect will be better!
These are all my personal experiences. I have lost a lot of weight. I hope I can help you!
