I have read his book, and the recipes in the book have taken into account the local situation in China. At least I didn't feel pluralistic and westernized when I did it. Today is the sixth day of my quick-acting period, and I lost 3~4 kg in the first five days. I don't know if you mean effective. I'm going to eat protein powder for two days and then change it into protein+vegetable protein powder for five days. I didn't go to their website to buy it. I groped for it myself. I want to reduce it too much. It's too expensive. . .
