Meal replacement powder is characterized by low energy, low moisture, low fat and high protein. Meal replacement powder itself is harmless to human body, and short-term use can really achieve the effect of losing weight. However, the daily calories in meal replacement powder are far lower than the daily calories needed by the human body. If the body is carried out without nutritional support for a long time, there will be many symptoms such as weakness, decreased immunity, dizziness and malnutrition.

At the same time, when we eat food at ordinary times, some foods have their own unique nutrients in addition to the essential nutrients of the human body. Although these unique nutrients can't play a direct role in the human body, they can help the human body digest and absorb the necessary nutrients in the human body. However, there are only essential nutrients in meal replacement powder, which will lead to the poor health of people who take meal replacement powder for a long time compared with those who eat a normal diet.

Short-term use of meal replacement powder can indeed achieve slimming effect, but this way of losing weight is unscientific. And if you return to a normal diet in the future, you may rebound and gain more weight than before you lose weight. So meal replacement powder should use it with caution.

Some foods can not only supplement their own nutrition, but also regulate the nerves, thus affecting the mood of the human body. If you take meal replacement powder for a long time, these foods will not be effectively supplemented, which will cause users to have sallow complexion, mental deterioration, emotional irritability and other symptoms.
