Ok, I haven't heard of this guy before, though from what I see, he did paleo for a while and then decided it wasn't working. The interesting thing about the article is the claims that low blood sugar/fat metabolism is stressful to the body, causes aging and inhibits the thyroid. He references Ray Peat and Chris Masterjohn.
So generally seems kinda counter to paleo (aside from him blatantly stating so), but it seems to be working for him. As people are often quick to point out when disproving the lipid hypothesis, counterexamples need to be explainable or you have to rethink your current model. So how are his results explainable under paleo and/or how is paleo incomplete?
