According to my personal experience, I play ball for about 5 hours every day, for about a month. You can't force it. If you want to play from the heart, you must play, so that you can count. In a month, you can lose 0. 127 kg on average every day. I began to like table tennis and played it for a month. Diet, sports ... all aspects are whether you can play table tennis or not until you beat the table tennis 10 champion held this month. I lost 3.8 1 kg, which is purely personal experience. Not everyone will do this, depending on your mood when you play. Anyway, I played very hard, and the class teacher actually challenged me and another boy in the class.
