If you want to be thin, you can't just run at night, but also match your diet. Eating less and exercising more is a healthy way to lose weight.
However, if you insist on running at night, it will definitely be good for your health. It can promote digestion and metabolism and help sleep.
However, it is not appropriate to go running just after dinner at night. You should choose the right time and carry it out in the right environment.
