Duoyan Zheng's practice is not difficult, but it is hard to stick to it. If you can really stick to it for a month and control your calories, you should be able to lose 8 pounds. Because Duoyan Zheng's weight loss book says that you can lose 4-8 kg in eight weeks (that is, 8- 16 kg). I only lasted for a week at that time, plus I didn't eat dinner, and I lost 4 pounds, which succeeded in flattening my stomach ~ ~
