How come your body burns 2000 calories a day by existing, but running a mile only burns 100 calories?

Question

How come your body burns 2000 calories a day by existing, but running a mile only burns 100 calories?

Answer 1

Running an eight minute mile takes right minutes.

Burning 2000 calories a day existing takes 24 hours.

If you were to run 8 minute miles for 24 hours at 100 calories per mile, you would burn 18000 calories.

Physical exertion burns a lot of calories, but you can only do it for so long. Base metabolism happens every second that you’re not dead.
