Specifically narcissistic personality disorder? I ask because some of the stuff I read on these blogs is just nuts. A week or two ago there was a post on Mark Sisson's site from a guy who looked normal and healthy and then started eating paleo. He looks better, sure, but I don't think there was anything wrong with the guy to begin with. I wouldn't say he was terrible. Photographic evidence here:
And then there's Jack's comment over on Free the Animal (this is Richard's "Penis Post"):
