The principle of meal replacement is to lose weight by reducing calorie intake. The reason why meal replacement is low in calories is usually because there is little or no carbohydrate and fat in its raw materials.

The basic principle of losing weight is that you can lose weight if your daily dietary energy intake is less than your daily body energy consumption. The energy consumption of the body is mainly completed by the basic metabolism and exercise consumption of the body. So if you don't exercise, you can lose weight just by meal replacement, but there will be many negative effects.

1, eating meal replacement will not improve your basal metabolism, on the contrary, it may reduce your basal metabolism, so if you return to a normal diet, you will easily regain your previous weight.

2. In the process of meal replacement, the nutrients of food will be destroyed, and the carbohydrates and calories of meal replacement are very low, which is needed by human body, so long-term use of meal replacement is not good for human health.
