Probably a straw man, but it's good to address at times:
Durant constructs an image of the “natural” that is entirely ideological. The real appeal of hunter-gatherer life is what he imagines to be its strict partition of gender roles, where “Men were hunters, women were gatherers” and where “women rewarded great hunters” with sex. Paleo eating is here connected with an image of society which reproduces itself largely through masculine competition.
Considering that Paleo and CrossFit have picked up a lot of pigs, jarheads and jocks, it's not a surprise that the Flinstones-Cave Man ideas filter into that realm, but it's just a mythos incorporated as a truth. The Paleo stuff is a solid base, but the devil is in the details and that's where a lot of this stuff falls apart in terms of social application. But it just means these people still buy into bullshit mythology, not that understanding hunter-gatherer biology and being INFLUENCED by their diet is a false-start. The whole gender role thing is patently false.
