Disclaimer: I've never been diagnosed with an eating disorder and as far as I know, don't currently have one.
From time to time over the years I've found myself weighing more than I really wanted to. There are two completely different ways I've responded to this at different times: (1.) weighing myself often and (at least casually) monitoring calories; or (2.) noting but "forgetting" what I weigh, going about my business, and letting my weight take care of itself.
With the second way, I've found that my weight fluctuates within a certain range (depending on things like how much exercise I get) and typically ends up somewhere in the normal range.
With the first way,
especially if someone else is leaning on me to lose weight, I've found that I usually feel hungry, I'm preoccupied with when I can eat again, and my weight either stays where it is or creeps slowly upward. My impression is that for me at least, following any concrete plan such as counting calories is a slow and painful way to
gain weight.
What happens when I ask myself, "Do I want to eat this?" seems to depend on where I'm coming from. If I've promised someone (doctor, family, friend) to eat a certain way, my usual answer is "Hell yes, I want to eat it, and if it weren't for my deal with (whoever), I would (mutter, grumble,

, ...)" If I
don't have anything of the sort hanging over me, I can listen for my own answer -- which, to my surprise, will sometimes be "Not really..." and other times, "Yes, I do."
