If you want to lose weight, you must control your diet and increase your exercise. It's like increasing revenue and reducing expenditure. You should control the calories you eat, and then increase the amount of exercise, so that you will lose weight over time.
Compared with running, walking has less pressure on the body. Some people's waist and legs are not particularly good, and they may feel heavy running burden. In addition, it is cold in winter in the north, so it will be a little difficult to run outdoors. You can choose to take a walk or go quickly. But the disadvantage of walking is that it consumes very few calories per hour, and the effect of losing weight may not be ideal. Better than sitting there.
If you run, it is obvious that burning more calories per hour is also beneficial to lose weight all over the body, not limited to a certain part of the body. However, it is necessary to warm up before running and stretch after running, which is helpful to relieve muscle tension and reduce stress and injury everywhere in the body. In addition, many people now say that people with a particularly heavy base weight should avoid running to lose weight, because the impact pressure on knees and ankles is greater than others, and they can choose other fitness methods such as walking and swimming.
The above is purely a personal opinion.
