I’m sure you’ve seen the psych research suggesting people have a finite amount of “willpower” they can exercise at a given time. It probably does make sense for some people to worry about hard-thinking (or other endeavors) than staying in top shape.
It’s not just that you only have so much “will power” that you ration, it’s that your brain doesn’t work when you’re starving.
I had to cut weight for wrestling in high school (from a healthy 185 down to 160) and the will power to not eat wasn’t even that difficult (though it did suck), but I still couldn’t think well.
