The running distance is too short. If you lose 4 pounds after running for more than a month, it only means that time is not enough. Jogging is the most fat-consuming aerobic exercise. It should be slow, and you can breathe normally instead of out of breath. Many people who lose weight run for more than 20 minutes before they start to consume fat, so keep it for 40 to 70 minutes. I used to run 10 thousand meters an hour every day. 1 month, lost weight15kg. Running for several months, from fat to thin. Skinny legs first, belly last. There is nothing special about thin belly alone. If you want to lose weight, you should keep running. On the whole, you will lose weight and your waistline will naturally become smaller. As an experienced person, I really experienced aerobic long-distance running alone, and my waist circumference ranged from 1 m to 74cm.
