You have more experience with fasting for weight loss than anybody I have been able to find on the forum and your story inspired me to fast for weight loss. I completed 7 days of fasting that I would never have thought possible if not for reading your story.
I believe we have to be careful about the advice we give to people who just pop in with questions like how much weight can I lose, and how fast can I lose it. Without knowing anything about that person its hard to know if they are suffering from and ED, so yes I think sometimes we do have to read between the lines. Especially since a trait of people with an ED is masking that very fact.
So in light of all that I think your questions were valid.
