I ran 16 miles this morning, burned over 2000 calories. But I won't lose any weight, I am going to eat those calories right back.

- tinymollusk 9y agoThat is indeed a substantial amount of exercise! Awesome work. In a thought experiment (where it's possible to know the exact amounts) -- do you think consuming exactly 2k kcal is perfectly even with burning exactly 2k kcal? IE, is there overhead to transform the energy? Does it account for physical/energy waste?
- drdrey 9y agoI don't know, anecdotally it seems that if I spent X calories exercising, my hunger will adjust until I consume roughly X extra calories. The energy expenditure does account for waste, I think only about 20-25% of the energy spent is turned into mechanical output
- niels8472 9y agoI have experienced the same issue when I burn larger amounts of calories. I've found burning about 500-800 calories (I run for about an hour) at the end of the day some time after dinner is my sweet spot.
