Kruse is still an enigma to me. His ideas sound interesting, but some things he doesn't seem to look into- like the smoking being harmful.
The nicotine connection with oxygen and red blood cells has been known. I wonder why isn't he talking about the effects on the brain? Sure, the energy system matters a lot, but so do other processes.
Although I don't subscribe to ketosis as even Paleo caused me issues without carbs, how can he group everyone into the same requirements? I think some body types do well on it and the rest of us do well with moderation and balance. The key thing is to avoid the wheat/grains/corn and dairy, which in another article are explained as the original GMOs, even before biotech firms butchered DNA.
On sott, someone commented on the naked ape hypothesis article that says it was for UV. There was back and forth about other factors that were ignored and wrong assumptions of everyone originating from Africa (which in genetic testing I heard has not been proven!) It also doesn't make sense that melanin acts like chlorphyll. If that is the case, darker skin should be up north where there is less light, in order to soak up more uv, and the lighter skin in sunny areas where harvesting this is less difficult. I'm confused.
There was one comment that pointed out the aquatic ape hypothesis, which in the iodine thread might explain why our systems need more iodine (which is more by coastlines, in the oceans too):
