Weighing more than 5 kg a week, unless the base is large, it is super harmful, and weight does not mean anything. I have a record that I cried and didn't eat or drink after quarreling with my boyfriend all day and lost 2 pounds. I'm only 88 kg, and I was only 86 kg in those two days, but it certainly won't last long, just because of water loss in my body. If I really want to lose weight, it will be a long process. My freshman year is about 100 kg. Later, many methods were used, and the effect was only 94 kg. Stay at 88 after work. Personal experience is indispensable for starting thin exercise. No violence. Jumping rope and walking backwards are quite effective. I usually walk backwards four times on the playground and jump 200 ropes back to the dormitory.
