Lex is being a little disingenuous re his rather glib mention of hand-wringing over cooking:- what he really means is that the bit of rendered fat works for him specifically, given his life-goals, not necessarily for anybody else. So, for example, Lex has no interest in heavy daily exercise and unlike many other RVAFers, he finds cooked meats to be less toxic to his system than raw carbs, etc. so this not necessarily 100 percent perfect combination of diet is absolutely fine for him, as long as his own personal health-expectations are met. (I note he still eats a lot of raw meat/fat, though, despite the above remarks re cooking).
However, plenty of others, like me for example, have few or no issues at all with raw plant foods but quickly get health-problems if they eat any cooked animal fats, rendered or otherwise. So, for such people, it is a hell of a lot healthier, to eat raw lean wild game and some raw carbs, say, than to eat lots of rendered tallow or other cooked animal fat. My own experimentation with raw, zero-carb and even a cooked zero-carb mini trial at one point) , however, showed that my health swiftly deteriorated and that there was no magic to the ketosis effect. Everyone is different, I guess.
