re above quote..."Red meat isn't on your plan because Warriors tend to be fast acetylators. What this means is that they typically have trouble cleaning out certain environmental toxins from their bodies..." Surely that should read "slow acetylators"?
They overprocess it and it turns into a toxin, as opposed to a slow acetylator such as explorers, who require red meats to function at their best regardless of bloodtype. For explorers it should be lean, whearas hunters and nomads do not have to be as concerned about fat content.
Basically A explorer types will actually require red meats (and other meats) to function their best. Lesser so than a hunter or gatherer though.
