There is a way, no diet, no exercise: go to the drugstore to buy a few dollars of "senna" (this is the name of the leaf, pure Chinese medicine, no side effects), and drink it with boiling water. Drink a cup every day, and adjust the amount and drinking time according to your own situation (my experience is to drink it every day after lunch until the water temperature is a little cooler, usually it will react after six to eight hours), because it will excrete all the excess nutrients in your body, that is, empty your stomach (it will be very poor in the first few days, but it will not be for a long time). The effect is very obvious. You can eat boldly without any worries. Economical and effective.
