How come your body burns 2000 calories a day by existing, but running a mile only burns 100 calories?
In: Biology
Someone let me know if my logic or math is off, but…
* If I’m burning 2000 calories per day doing nothing, then that’s 2000 calories / 24 hours = 83.333 calories/hour for sitting on my ass, typing this out.
* If I run a mile, that’s 100 calories for about 7 minutes, 30 seconds. I’m using [this resource](https://runninglevel.com/running-times/1-mile-times), which averages times for males and females for a range of ages and skill levels.
* So if I’m running a 7:30 mile, then I can run 8 miles in an hour (60 minutes divided by 7.5 minutes/mile = 8 miles).
* To compare my calories burned per hour, running 8 miles an hour x 100 calories/hour = 800 calories/hour, or nearly 10x what I’d burn in the same hour, just existing
* Or in other words, running for 2.5 hours (2000 calories, divided by 800 calories/hour) would burn a day’s worth of “just existing” calories.
* No it’s not 5YO math, but that’s about as simple as I can get it.
