It is generally recommended that the jogging time for weight loss should not be less than 30 minutes. In the first 20 minutes, jogging mostly consumes glycogen in the body, and it takes 20-30 minutes to consume body fat. Moreover, because the slow running is not very intense, it will not make the body go too far and lack oxygen, so it will help the consumption of fat, and then achieve the purpose of losing weight.

It should also be noted that whether running or not, what kind of "fuel" the body chooses to consume does not depend entirely on the exercise time, but also on the exercise intensity, that is, the running speed. At low speed, the body will burn fat; At high speed, it will burn sugar. When the heart rate is from 120 beats/min to 140 beats/min, the oxygen uptake is the maximum. When the heart rate reaches 140 beats/min, the heart rate increases again and the oxygen uptake decreases. The higher the heart rate, the less oxygen intake. The heart rate is between 120 beats/min and 150 beats/min, which is the valid range of running.

Finally, it should be noted that running to lose weight focuses on persistence. Everyone's physique is different, and the speed of losing weight is different. At the same time of exercise, the diet should be appropriate and reasonable, and follow the principle that intake is less than output. Before and after running, you can do something to improve your body's metabolism in the new city, so that your muscles can relax and you can lose weight.

I hope I can help you and be adopted.
