Probably just echoing what others here have said, but I think the improvement on carnivore has a lot to do with what isn't being consumed. Primarily plant defence chemicals in photosynthetic tissue and seed armor. Also, meat is very nutrient dense and digestible, particularly digestible when undercooked.
My perspective is influenced by my background as a botanist and ecologist.
