Neither does cold-blooded logic. Nobody can understand obesity unless they've had to ask themselves "wait, why did I eat all that?" Willpower seems to be finite and its relationship to blood sugar may be genetic. I've had pretty good luck losing weight using protein/fiber shakes between small meals to reduce blood sugar spikes and blunt cravings that were hard to control otherwise.

Yes and no. There is a thin line to walk here. On the one hand, there is a definitely harmful component to the fat acceptance movement as you point out. On the other hand, discrimination and humiliation of obese people is wrong and counterproductive.

But the fact is that there are some people for whom obesity is actually a medical problem that has nothing to do with self-control, and a statement like the one in the TFA demonstrates considerable privilege blindness.
