The correct apple diet is to eat only apples on the first day. It is best not to exceed six. Drink milk the next day, the best skim, no more than 1ml. You can't drink water for two days. Return to normal diet on the third day. Because the abnormal diet in the first two days will make it difficult for the stomach to adapt at once. I suggest drinking more water, and eight glasses of water a day is the best. But it's best not to eat too exciting food for three meals, mainly light, and then eat casually … Apple diet is a good way to lose weight, good luck!
