Errr, Last I checked lex gave up on all plant-food, in the last few years. At least that's what he told me. He does eat cooked animal food(pemmican) and cooked meats but that's it, AFAIK.
Ah, OK, thanks.
It seems that zero-carbers can quickly get issues when even eating a small amount of carbs due to not having the right bacteria(or enzymes?) to handle it after successfully adapting to 0 carb for a long time.
I get issues with carbs and I haven't gone truly 0 carb yet, and it's incredible how rapidly and positively I respond to an all-meat/fat diet. I speculate that maybe I'm descended from people who were hunters of big game and therefore heavy meat eaters or maybe the damage to my system makes me unable to handle carbs. There is apparently a history of Central Asian peoples (such as with the Tatars of steak Tartar fame and the Mongols) being heavy eaters of the raw meats of animals like horses, cattle, reindeer and wild stags and boars in more recent days, and probably bigger beasts like aurochs and mammoths in the ancient past.
I notice that others in my family are major carb addicts and both type 1 and 2 diabetes are common among my relatives (though my own blood sugar was never measured until after I went Paleo, AFAIK), so sensitivity to carbs seems to run especially strong in my family. I know that the Irish, Welsh, Basques and others have been specified as having particularly ancient genes that are nearly unchanged from Mesolithic hunter-gatherers of Central Asia, who might have eaten mostly big game animals. Its speculation, but maybe that has something to do with it. I would guess that Middle Eastern and Mediterranean peoples might tend to handle carbs a bit better than a true bloodthirsty savage like me.
My people were the sorts of barbarians that the Romans and other empires sought to either enslave or cleanse forever from the earth (though the Romans probably never quite made it to Ireland--legend has it that they thought Ireland was even more savage than Gaul and therefore not worth the bother of conquering). I am of the defeated peoples.
The ancient and doomed ones.
Interestingly, we of the ancient Irish are also apparently related to other doomed hunter-gatherer peoples like the Algonquian-speaking Indians, according to DNA analysis. Which is not surprising, because many of the North American Indians have long been suspected of originating in Central Asia.
