The so-called unhealthy three-day apple diet is to eat only apples for three consecutive days without eating other fruits and food. You can eat apples according to the time of three meals, or eat them when you are hungry until you are full. Any kind of apple will do, but red apples are the best. Green apples are sour, for fear that they will irritate the stomach. Apples should be eaten fresh, washed and peeled to avoid pesticide residue. During these three days, when you are thirsty, you can drink boiled water or non-irritating tea, such as mint tea, wheat tea, safflower tea and houttuynia tea. During weight loss, your stomach will be very sensitive, so avoid drinking caffeinated drinks, such as black tea, coffee, green tea, oolong tea, etc., to avoid stomach upset. If constipation occurs during apple weight loss, you can drink one or two tablespoons of olive oil to moisten your intestines on the third night to promote the excretion of toxins accumulated in your body.

However, you should pay attention to the main points of diet after the three-day apple diet, otherwise it will be easy to hurt your body as you said. After the three-day apple diet, your stomach will be tender, your taste will be sensitive and your stomach will become smaller because you are far away from irritating food. Starting from the fourth day, your diet should be slowly restored. You should not eat a lot of food at once, especially don't eat snacks. In the first three days of restoring diet, it is best to start with eating porridge and tofu. In short, when you resume your diet after losing weight, the food should be light and not excessive, so that the effect of losing weight will last. Apple's weight loss is equivalent to a general cleaning of the digestive system of the body. If you are really fat, it is impossible to get back into shape if you want to make an apple to lose weight. It is best to do it once every month or two until it is reduced to the ideal weight.
