It is more appropriate to run 15 to 20 minutes in the morning, depending on the physical fitness and health of the runner.

I have the following suggestions about running time, running mileage and diet after running:

(1) Persistence is the most important thing in running. You can't run too much and too far at a time, just run the right amount of mileage, then keep running every day, and work hard day after day, and you will slowly see the effect. 1.7 m 140 kg, you can run 6000 to 10000 m every day, and it is better to exercise for more than half an hour.

(2) Try not to put the running time in the morning, and it is best to choose to run at four or five o'clock in the afternoon. Pay attention to replenish water after running, but don't eat right away. For a figure of 1.7 m 140 kg, you can postpone dinner a little, but don't give up dinner. It is suggested that you can eat less foods with high fat content.
