You're letting that word do some very heavy lifting.
> To make a comparison
I think the comparison is very weak, very superficial. The human body is way more complex than CICO. But your comparison does have some intuitive value -- there are more than a few people who consistently spend every penny they make, and sometimes more, just trying to survive. We don't see a lot of them on Hacker News, to be sure.
> The human body is way more complex than CICO
The human body is way more complex so as to defy the laws of physics as we know it? The human body cannot create matter. In order for it to increase in mass, you must be inserting extra mass into it.

Genuine quesion - if I eat 1500 calories today and do a measured 2000 calories of work on a treadmill, where did that extra 500 calories of energy come from?
Are you suggesting my body can create energy from nothing?
What word would be better than “choose” in this context? For the majority of people who aren’t prisoners or toddlers, there is a good deal of personal choice that determines what foods we eat and how much.
Even if fate has it that I must end up at a Wendy’s drive thru tomorrow night, couldn’t it be true that I could choose to eat the 400 calorie meal instead of the 800 calorie meal, or order water instead of Sprite?
