About running to lose weight, I am a boy, with a height of 175 and a weight of almost 200 kg! Although heavy, it is not puffy. Because home is in the countryside, there are many jobs.
Running to lose weight must take more than 40 minutes to be effective. Because in the first 40 minutes, the human body consumes the sugar in the body. Only after 40 minutes, the sugar in the body has been consumed almost, and it has begun to consume its own reserve energy-fat. Therefore, if you want to lose weight, you must keep running for 45 minutes to an hour every day. The distance is about 10 km, and the school playground is 400 meters long, with at least 20 laps.
