I don't think he specializes in eating disorders, but he himself lost 40 lbs about 5 years ago and kept it off. And he's not that tall so that was a fair amount for him. Not too personal - your question made me think of my answer this way, if that makes sense! The hardest part is just making it okay to eat anything at all and admit to it. I don't know why that is. I remember telling him, "I'm allowed to eat!" I didn't mean handfuls of candy or anything - I meant regular meals. But I don't think he understood me at first.
