Keep running 10 km every day and lose a few pounds a month. If you persist for a long time, you won't get fat, but you can still keep in good shape.
Of course you can lose weight. Long-distance running and brisk walking are the best ways to consume body heat, but you must try to exercise at the same frequency. Because at the beginning of exercise, you consume your daily blood oxygen and sugar. When the same frequency is accumulated for a certain period of time, it will promote fat metabolism (so-called fat burning), so that with the accumulation of the amount, the weight will naturally drop. But running consumes abdominal fat relatively slowly. If there is a lot of abdominal fat, it is recommended to do more abdominal massage or sit-ups. Long-term adherence to long-distance running will be of great benefit to the functions of various parts of the body, and so will brisk walking, which is only determined according to one's physical condition.
