Basically useless, no effect at all, practical skills to lose weight. My colleague has personally experienced that eating and drinking water are separated, that is, dry and wet separation. After eating 1 hour, drink water instead of porridge; Don't gulp water. Drinking water will make you fat, that is, drinking water too fast. Make sure to eat breakfast and lunch well, eat a small amount of boiled vegetables and cabbage as staple food for dinner, and make sure to lose weight obviously after half a month.
