My sister used to eat only apples every day, but she lost weight about 1 1 kg in two weeks, and then she couldn't hold on. According to her, it hurts.
Now she is still losing weight, but mainly apples (it is the season of peach production, and a peach every day will definitely be good for her health, especially for girls). She eats a small bowl of rice porridge in the morning, moderate vegetables at noon (lightly cooked) and only apples at night. So far, she looks good and healthy.
This method is not to lose weight because of water loss (Baidu knows the benefits of eating apples). Drinking too much water will do harm to one's health. Health is capital, and a good figure should be built on it. I wish you success in losing weight.
