The test is: would you REFUSE to attend, say, a wedding/funeral/important event because high-protein food would not be available and you hadno protein meal replacement bars handy? if you would go, but grumble and train harder the next day, imho, no disorder. If you wouldn't hate yourself for it, no disorder. If you wouldn't think of suicide because you feel so worthless for eating a piece of non-healthy food, no disorder....
