But you already speculated by claiming it's not 100%. So either you have another number in mind or are just being contrarian...
Further, your experimentation has a flaw; no two things carry identical risk factors and "willpower" factors. Food, as anything, is unique, so the idea of comparing it to other willpower exertions isn't relevant.

So, you're backing away from the idea that people who struggle with weight lack willpower and are shifting to the stance that they lack some hunger-specific willpower that's unrelated to anything else meaningful?
That's completely indistinguishable from the idea that some people feel hunger more than others.
Nope, I’m reasserting that applying willpower to food consumption is completely possible, and to claim that willpower isn’t a skill is to deny decades of research that shows over and over again that it is.
