I don't know what your perseverance is/you need strong self-control to lose weight, otherwise you can't succeed. Do you control your weight now or continue to gain weight? If the weight remains the same, the diet should not change much, that is, dinner should be finished before six o'clock.

People's metabolism is the fastest when they go out to run at 8 pm 10 (not walking as you said, it will only thicken their calves. Anyway, during this period, if you are tired from running, stop and do some stretching exercises before running, because after 40 minutes of exercise, people will consume body fat and drink more water. After losing weight, you can also go to fitness and play with equipment, which consumes the most calories. You may not be able to play this device now. If you have any questions, you can ask me. I once lost weight 10 kg.
