I wonder if there's a point where being starved makes you so out of it that it's like being on dope or something. Whereas every time they have a good meal, they get lucid enough to freak out about the state they're in, and they don't like it.
No, it does not have that effect.
That's one reason it is so hard to treat anorexia for example, it literally makes them stupid and they can't think rationally until they've been fed for months and long term inpatient care for an anorexic adults is pretty much impossible to enforce because they refuse to comply with the treatment for the amount of time needed for their brain to start functioning again.
And involuntary care ain't going to happen due to them not being an acute threat to themselves.
Also, they usually are in a state of cognitive dissonance where they know that they will die or end up with irreversible damage if they continue their behaviour, but they can't
feel it, but they sure feel the anxiety of going through treatment.
Not to mention that most of the severe cases thinks that they will lose their identity if they recover, because they've been sick for so long that they have few friends, no romantic relationships, no hobbies, no job, they don't even have a relationship with their parents outside of being sick.
