Regardless of the specific content, as far as your expression is concerned, you don't know how to lose fat.
You should have a goal first, and then see if the plan is appropriate. When making a plan, you should first consider the coordination between exercise intensity and exercise time.
When making a plan, the first thing to look at is the body fat rate rather than the weight. What is really related to weight is the way of exercise, but it is only how much you walk, and there is no intensity regulation.
Therefore, whether walking or running, we must first make sure that the "bull's-eye rate" of reducing fat for about 30 minutes every training is the most ideal.
