First, the nutritionist won't be judging you at all (at least a good one won't!) I was worried about the same thing, and T and I spent the days leading up to my appointment with the nutritionist talking about my fears around working with one - with that judgement being the biggest one.

My first appointment was an hour and a half. She asked if I could keep food records for a few days prior to coming, just so she could get an idea of where I was. I was apprehensive about this but it was actually ok. Yes, there was a lot of repeat info that I had heard from my doctor as well, but it was with the nutritional spin and it helped to hear it twice.

She started with me where I was, there was no pushing of anything, except some major importance on getting my calorie count up to a certain level (which was still an ED level, just higher than where I was, cause where I was was causing my organs to struggle.) Otherwise, we went really slowly, working with my safe foods for a while, and eventually (we're talking months) expanding the variety ever so slightly.

The nutritionist's goal was to get me to a place where my body was healthy enough to function (cause it wasn't) so that we could work on the mental aspect of the ED. That took a good 6-8 months. It's now two years later and I've tapered down from every week with the nutritionist to once a month with email check in as needed.

My suggestion to you would be to be upfront with your fears and apprehensions so she can best work with you to appease them. I'd also ask about her boundaries/communication expectations. I know it helped me to be able to email my nutritionist whenever I needed to.

Good luck! The first visit is the scariest! My nutritionist is a much loved member of my treatment team, second only to my beloved T!
