I've said this before, and I will say it again. In order for something to meet the criteria for a disorder, one specific criteria has to be met according to the DSM-IV-TR:
C. The symptoms cause clinically significant distress or impairment in social, occupational, or other important areas of functioning.
If you answer yes to this question due to your current bodybuilding diet, then, yes, I would say its a disorder. If you answer no, then, no, you don't have a disorder.
Diagnosing is not black-and-white. Just because you follow a certain diet or eating regimen that doesn't automatically make it a disorder. It's not that simple!
