It actually points up something I may post about at some point, which is that statistical science itself is often a dead end - you can publish paper after paper after paper about effects that show up in 60% of the population - but you don't know what separates the 60% from the 40% - and still have no real grasp on the phenomenon and no real ability to manipulate it.
I'd be very interested in such a post.
I recently came out against paleo in the open thread, and realized that I probably haven't yet heard the strongest arguments in favor of a paleo diet. So, what are said arguments?
EDIT: Or more generally, why should I eat less carbohydrates and more protein / fat?
