I personally represent this. First, this meal replacement powder is not a diet pill, it's all whole grains, and it's not doped with any pharmaceutical ingredients, so it won't have any side effects. Second, the effect of meal replacement powder varies from person to person. Some people will lose weight after eating for a few days, while others will lose weight after eating a box. But it is necessary to lose weight, because its calories are low, and everyone can lose weight as long as they eat as needed. Third, my mother will eat this zd product by herself. She only eats one meal a day. Although she is losing weight slowly, she said that her stomach has become smaller and her body has become much stronger after eating this product.
