Well, I've lately taken to having protein shakes after the crossfit workouts, so I probably protesteth to mucheth. But yeah, the paleo-evangelism is the one thing I really don't like much about crossfit. I just do my best to ignore it. (And then get all ranty online, apparently.)

But I totally sympathize with tailoring your diet to what makes you feel good and what works for a given person's level of activity and their goals in terms of endurance exercise or gaining muscle or whatever. I quibble with the alleged benefits of never eating a bean or a slice of bread or more than a third of a banana.
