The reasons are as follows;
The intensity of walking is very small, and it consumes less calories. And it doesn't have much effect on improving people's basic metabolism, so the effect of walking to lose weight is not very good.
Walking doesn't require much physical strength, and most people can walk, so they can walk at any time of the day, preferably after meals. As the saying goes, walk a hundred paces after a meal and live to ninety-nine. Walking after meals can reduce the accumulation of body fat. Can play a role in reducing fat.
If you want to run, you can't do it at night, because running is more intense, so you should choose to run during the day and at night, which will lead to nervous excitement and affect the quality of sleep at night.
