First of all, you don't get enough exercise every time and want to lose weight. Jog for at least 40 minutes at a time, usually about 1 hour. You can't lose weight in less than 40 minutes, because the burning of fat in your body starts 30 minutes after exercise, and you can't lose weight without burning fat for half an hour.

Secondly, exercise to lose weight focuses on persistence and persistence, so you should exercise every day, which will have good results. I suggest you do it in the morning and evening.

As for the precautions, if there is a plastic track where you live, I suggest you jog to the track every time so as not to hurt your knee easily. If not, pay more attention not to run in uneven places when running, which will easily hurt your knees.

Pay attention to your diet at the same time. Don't eat salty and greasy food, don't drink any drinks, drink more water and eat more fruits and vegetables. If you cooperate with exercise, the slimming effect will be much better.
