Milkshake meal replacement not only has no weight loss effect, but also will do some harm to our health if we eat it for a long time. Because milkshake is a kind of liquid food. If we don't eat and eat vegetables for three meals a day, but only insist on eating liquid food like milkshake, the stool in our body will not be shaped and normal metabolism will not be achieved. If this happens, what our body lacks is not fat, but health.
