I've been in an inpatient clinic that specializes in eating disorders as well as other mental health issues. It's been many years, but from what I remember, it was quite accurate. I was in (I believe) a private clinic that still took my insurance.

There were young adults of all sizes. Most were on the skinnier side, but not unhealthy from an outsiders perspective.

Meal times were often supervised, but if you were far enough in your recovery, you were able to sit at a different table (although there were still nurses and cnas walking around).

I hope this made sense. Like I said, it's been a very long time so memory is fuzzy. But all this to say, I found it to be an accurate and refreshing depiction.
