Just like why the thinner you are, the more you want to eat. First of all, when you lose weight, you may eat nothing. Your stomach is empty and there is no food to digest, so you will always want to eat. Man is iron and rice is steel, and no one can live without it. You can stop eating so much, but you can never eat on an empty stomach. You can cook some light fat food to eat, such as vegetables, or some boiled chicken breast, which is still edible. After all, they are fat-free
I remember a classmate of mine in college who was very fat. Then he learned a way to lose weight online, that is, he didn't eat rice for a month, only drank water and an apple. A week ago, he was able to hold on. He drinks water every day when he is hungry, and then dinner is an apple. By the second week, he even had no strength to wash clothes. I'm sleepy every day, and my whole body is soft. In the third week, he couldn't get out of bed at all and had to eat. The whole person fainted and said that he was really light.
But his weight loss is just a sign of dehydration. When he starts a normal diet, his weight will come back soon, so this is not feasible. Usually eat less and more meals, less greasy and more light. Usually, we should cooperate with some exercises to achieve good results.
