Brian, you need to interview some carnivore peeps who have hiked the canyon rim to rim. All this talk of glucose and carbohydrates, I wanna hear from someone fat adapted and not consuming carbs. I would be curious if they find it easier. Dr. Shawn Baker has had interviews with people eating carnivore who have run marathons without eating or even drinking (which I find wild!). Surely someone has done this, or else is it going to be n=2 for us after we go here in just a few weeks? Haha! Thanks again for a wonderful and very helpful podcast!
