I could probably gain a
lot of weight if I wanted. I could stop doing cardio and eat more. I'd
prefer to eat more. I'm not saying it's my will. But I have other
priorities above eating. I def eat junk food sometimes when I "don't
really want to," but most of the time I'd love to eat cookies, ice cream, etc but other preferences make me
"choose/decide" that I'd rather not.
I agree I'm genetically thin. But other environmental factors along with my personal interests keep me thinner than I could be if I ate more.
I admit this creates a bias in me. But I think it provides the framework for the flip side.
People heavier than they say they prefer have whatever their genetics, environment, and personality traits are. They cannot control many of those factors, especially the ones in the past, even more so the ones decided by their parents/guardians. And so, when they want a cookie, which I often do too, they have differing other factors that may or may not lead them to not eat the cookie.
And since childhood and genetics are such major factors, how much choice do we have? I suspect there is a spectrum. And I suspect this same reasoning could be applied to other areas like addiction or education.
