Drinking a glass of pure milk four hours before going to bed won't make you fat. Drink 1-2 cups of milk every day. Try to drink some low-fat or skim milk, and you can also drink yogurt. These calories are lower than pure milk, so it is not advisable to gain weight after drinking. In addition, a reasonable diet every day can lose weight. Besides, I lose weight faster with Meimei. I lost more than 22 Jin in a month. Losing weight is really great. Besides, I eat three meals a day. ~
