If you can persist for a month, it is almost impossible not to lose weight unless you overeat, because running consumes too much energy at the same time.
I suggest that you can increase your patience by cooperating with others, and don't run in a few days (don't run too hard a few days ago, and you can't stick to it later). It's easier to run tasks at first, and then you can add them slowly. Be sure to run until you sweat, and don't rush for success. It is impossible to lose a few pounds in a few days)
