Saying that a person's normal pace may lead to a concept, that is, taking a treadmill as an example. Several common gears on the treadmill, 3 6 9 12, are freely adjustable. The speed of 3 is slow, but the speed of 6 is a little fast, so the speed of 5 is in the middle, which means walking 5 kilometers per hour. At this time, your energy consumption is about 400~500. So if you run, that is to say, running for an hour consumes twice as much energy as walking for an hour.
Walking also consumes energy, but this process is slow and not suitable for everyone. Running is a good activity if your own physical stress is not so great. If you keep a speed of 9, you are jogging at a speed of 12, which is a standard of running fast. You can adjust according to your own physique, or take a proper rest. It just means that people who are particularly heavy are not suitable for running to lose weight, because running is not good for you.
I don't think exercise consumes energy, especially exercises muscles. It is to exercise the explosive power of your muscles, not endurance. Aerobic exercise is to exercise a person's endurance, while anaerobic exercise is to exercise explosiveness. It can be said that normal people can do it, but the effect may be affected to some extent, because people's body can't get great growth in both endurance and explosiveness, and there must be one aspect that is more important.
