I've found 2 camps
those of us that seek learning and found it on our own
we tend to be the "nerd" because we have brains and seek knowledge on our own
Then there are those who are paleo/etc because they were told to. Less interested in science, they are merely following rules to get results I.e. Crossfit
(not all crossfitters fit solely in type2)
personally I'm a nerd jock
I love activities, Ultimate Frisbee, Biking, Hiking, Volleyball, Tennis, Belegarth(Paintball with swords)
and so I focus even further on pinnacle of metabolic advantage I can get to help me in these sports, yet I found it because I love reading and learning about everything
Any real research about optimal health leads you straight to paleo
any desire to discuss with likeminded intelligent individuals leads you here.
