Actually, losing weight is not that difficult. Listen to me every day and do math problems for five hours. If it's not enough, do whatever exercises you think are the most difficult, and do a lot. In addition, in order to combine work and rest, you can skip rope in the morning without too much, 150 is enough. In addition, snacks are usually not eaten for three meals. Study against the clock, of course, so that you won't always think about eating.
