1. Affect the stomach, causing diarrhea, constipation and other uncomfortable symptoms. Because the dietary fiber in meal replacement powder may be high, and the proportion of ingredients is different from that of traditional foods, it may contain ingredients that the human body cannot fully digest. Long-term consumption of meal replacement powder will stimulate the stomach, leading to diarrhea, constipation and other uncomfortable symptoms.

2. Insufficient or unbalanced nutrition: Because meal replacement powder generally contains only some nutrients needed by human body, it can't replace the whole traditional diet, but only a part. Therefore, excessive dependence on meal replacement powder will lead to insufficient or unbalanced nutrition, and even have a negative impact on health.
