Disease analysis: if corn is used instead of staple food (rice, noodles, etc. ), it will have a certain effect, but if it is done for a long time, it will lead to uneven nutrition, so eat more fruits, otherwise the resistance will decrease, and the skin will become rough and the loss will outweigh the gain. Suggestion: Excessive dieting is not recommended. Dieting is necessary, but the amount should be reduced slowly and appropriately, and certain foods should not be excluded. In the long run, in addition to the imbalance of nutrition will affect health, once it is not adhered to, it will rebound (basically). You can appropriately increase some exercise, reasonably arrange your diet, ensure your nutritional needs, eat less high-calorie and high-fat foods, and don't eat after 9 pm.
