For some people, black coffee can make people's skin dull, not only can't lose weight, but also make people's skin poor and their sleep quality poor. Good sleep can improve the speed and efficiency of losing weight. If you can stand it, I recommend the following methods. If you really hate your current figure. The consequence of this method is that after I have lost 20 pounds, I will feel dying after climbing a flight of stairs, and it will take a long time to recover, and my face is not good. For three months, I only drink a few spoonfuls of honey and warm water in the morning, noon and evening, eat nothing, and occasionally eat some fruit. There are only two kinds of fruits to eat: apples and pitaya. Bananas, durians, lychees, watermelons and grapes are all inedible. Distract yourself from thinking about what to eat. Effect: I lost a lot of weight, but due to lack of proper exercise, my whole body was loose and I looked ugly. If you think you can't hold on, don't do it. It's up to you if you don't implement it. If you change your mind and want a safe, reasonable and stable scheme, you are welcome to come to me. I hope I can help you.
