Eating apples in moderation will make you thin. Because the intake of apples is reduced, digestive organs such as the stomach can be recuperated. It can also make the human body consume less calories, and the insufficient part needs fat supply. The excess fat in the body is reduced, and people will naturally lose weight. However, if you eat too many apples, the protein intake of apples will be too small. The lack of protein will cause muscle loss. After muscle reduction, the calories will be less likely to be consumed, and the fat will be more likely to accumulate. It will become more and more difficult for you to lose weight in the future.
