"But not the whole thing. I could make conscious choices to make my body healthier. But I don't, and therefore I can accept at least a little bit of the blame."

"But not the whole thing. I could make conscious choices to make my body healthier. But I don't, and therefore I can accept at least a little bit of the blame." I think this is the sad truth of the matter (at least for now). People tend to fall into one of two camps: 1) Those who believe that obesity is largely (if not entirely) the obese person's fault; 2) Those who believe that obesity is heavily influenced by factors outside of conscious control, and therefore, there's nothing to be done about it. The truth is somewhere in the middle. Some people are luckier than others, genetically or epigenetically. The unlucky ones will put on fat more easily, and they will have a much harder time losing it. So that means they need to work twice as hard (if not 100x as hard) to keep it off. It's a shitty break, but it's the truth. I grew up fat. Losing that fat took nothing short of a Herculean (and borderline unsustainable) dietary effort. I mean, I lived like an ascetic monk, depriving myself of any and all pleasurable food, for the better part of a decade. I worked out like a crazy person. And even today, keeping off the fat requires a constant vigil over everything I eat, and the amount of exercise I do. I wasn't responsible for getting fat in the first place -- I lost a prenatal dice roll -- but I did take responsibility for battling the bulge. "Continually reiterating the thermodynamic dietary hypothesis to me (energy eaten minus energy expended) does not help. I doubt it helps anyone except possibly those who do not already know what a kilocalorie is." Agreed. It's also willfully reductionist, and it smacks of passive-aggressive moralizing. To me, rattling off the calories-in-calories-out line is no more helpful than calling obese people lazy, stupid, irresponsible, or sinful. (And in basically 90% of the contexts in which someone says it, that's the subtextual insinuation.) It's unproductive. It's an attempt to close the case summarily, and this case needs to stay open.
