It's a bit difficult to lose twenty pounds a month. Let me tell you my way to lose weight, that is: Pu 'er lotus leaf tea (when you drink water, it will have an effect after a while).

Note: You may feel hungry after drinking tea. Try not to eat.

In addition, with some exercise, you can go to Taobao to buy a set of "sauna clothes", which can make you sweat more.
