From my experience, yes. I don't have any body issues (if anything, I think I look much more ugly being so bony than I did before) but still been suffering from ED. For me it stems from being majorly overweight most of my life and nowadays wanting to "eat healthy" (rather than to look good/lose weight).

It's actually why I had little interest in most of the ED books I read, so many focus on body issues I simply couldn't relate.
