Pu 'er tea can definitely lose weight, because I have tried it myself and can scrape oil. But the problem is that after drinking Pu 'er, the appetite will become more vigorous. After all, after shaving, you will want to eat more. If you can control it, you should be able to lose one or two pounds a month. But after a long time, the body will form a new balance. Then it can't be reduced unless it is increased. But eating too much of anything will have side effects. So it's best to exercise, but you probably don't like sports when you ask questions.
