Overeating is the addiction of choice of carers, and that's why it's come to be regarded as the lowest-ranking of all the addictions. It's a way of fucking yourself up while still remaining fully functional, because you have to. Fat people aren't indulging in the luxury of their addiction making them useless, chaotic, or a burden. Instead, they are slowly self-destructing in a way that doesn't inconvenience anyone. And that's why it's so often a woman's addiction of choice. All the quietly eating mums. All the KitKats in office drawers. All the unhappy moments, late at night, caught only in the fridge light.
