Losing weight by eating only fruit meals is highly unscientific. Because fruit cannot meet the essential nutritional needs of the human body, the normal functioning of the body also requires other nutrients such as protein. Eating more fruit is indeed beneficial for maintaining inorganic salts, but fruits lack components such as iron and calcium. Long-term use of fruit as a regular meal will inevitably lead to a deficiency of these substances in the body, causing anemia, and over time, it may also lead to other diseases.
