I wonder about that too. How many "healthy" eating styles would fall under that heading? It, to me, appears to be like a chicken-and-the-egg type thing where people with eating disorders pick up a tiny bit of science and find a "home" there. If you pick an eating plan with elements of your disorder, just like Lisa said, you can use it as a smokescreen.

I know binge eaters who claim to be doing CAD, anorexics and bulemics who take Atkins to the extreme, living on the fat fast and claiming they're too "metabolically resistant" to lose on induction when they already have a very low body weight...

Actually, I was suprised to find that one of the red flags for ED is the elimination of entire groups of food as being "bad". Whether it be fat or carbs....
