Eat less, it's not good for your stomach. My former classmate tried, but she didn't eat breakfast, weighing about 4 kg a week? I don't remember. But I know that I drink a hot kettle every day, 60ml at 3 o'clock every day, and then run about 1000 meters every night. I stopped eating after 7 o'clock, and I ate as much as I should for three meals (in fact, it was a little too much at that time). And then lost two A Jin weeks.
