I don't know what Crossfit is, and I'd never heard of a paleo diet until recently when I read about it on this forum. 
I gave up discussing diets with people back when Atkins became popular. Too many people thought it was the best thing ever because they'd lost so much weight. Of course they admitted that they had gained it all back and more when they went back to eating "normally," but that didn't stop them from singing its praises. It made no sense to me. And then I read that many people had bad problems with constipation when they first started the diet, and that just seemed like a deal breaker to me. But if someone wanted to insist that eating a stick of butter and a pile of bacon for dinner was better for them than eating bread, I saw no point in arguing.
