This can't be generalized. The pressure of work in the past few months was too great, and due to factors such as diet, my S-shaped figure was seriously out of shape. I bought the German Tchibo black and white instant series recommended by Baidu and Taobao, which tasted slightly bitter. Drinking a cup of black coffee before and after meals was very full, which was said to be very helpful for keeping fit. Friends who are not used to this taste should start with caution. Anyway, I am used to this brand, and it has always been this. No sugar or milk is added, and those added instant coffee on the market are completely crushed. After drinking it for more than half a year, I lost more than ten kilograms. Anyway, everyone depends on their own situation, I hope it will help!
