I have been really lucky to have had a couple AMAZING dietitians that I have worked with the past like 10 years. Honestly, it has depended on how much I was working to follow their advice and work towards the goals we set. There have been times when my body has stayed constant within its set-point and other times where because of the eating disorder it changed a lot while working with them but I will say that rationally I have had great dietitians I could really trust that were not trying to get my weight anywhere besides my natural healthy maintenance point... if I would have been following their advice 100% of the time all these years my weight probably would have just had normal small fluctuations and stayed right in the healthy range they want me in (even if at times I won't admit that is true because of the eating disorder)... They have literally been life savers for me.
