That's a bit of a special case, because shaming creates stress, while people with an eating disorder eat to reduce stress. Otherwise, I think it's self-evident. There's many behaviors that would've been socially unacceptable a hundred years ago, which today are accepted and far more common. For a somewhat related example, consider inter-racial or (to some degree) inter-religious marriages.
