I came from high school myself. I weighed as much as 125 kg in high school. At that time, I was under great academic pressure and had a good appetite. Later, when I saw that I was really fat, I began to control it. First, I removed the extra meals from the evening self-study, and my appetite was no longer half. At that time, we let ourselves exercise for half an hour after two classes every afternoon. I just ran in the playground and quit snacks for half a year.
