Answer 1

Just want to point out that while an activity may consume an estimated amount of calories, the real calories required to do the activity, plus repair and recover from depleted stores of different biochemistries is never accounted for but necessarily required.

Take for example, running a marathon. It might say… burn 3kcal on paper. But the subsequent rebuilding and repair of damaged tissue is gonna to use wayyyy more than that.
