The easiest way is to eat normally in the morning, reduce the amount of food at noon to half of the original, and try to only drink porridge for dinner. The most important thing is to exercise for at least two hours every day, such as jogging, running and jumping to lose weight, which can reduce at least 15 kg a month. Many of my classmates are very thin. Stick to reducing thighs and you will naturally lose weight. Don't just exercise alone in one place, you will grow muscles. In addition, it is best to take a bath and massage your body after exercise.
