I have no idea what the answer to your question is, but I am also interested in this. It doesn't matter if I am not eating, purging or over eating, my therapist has never addressed it and just says "you look ok" like looks is all that matters. I can't imagine that proper therapy for eating disorder would involve them making you gain weight without addressing the underlying issues.

Sorry your T just told you to eat yogurt, that would really piss me off too.
