He explains it further: "Your brain has been running on low energy for decades and it can just shrink and atrophy and get worse. Switching over to ketosis through a ketogenic diet and having ketones running your energy structure just bypasses that—you don't need insulin and it just goes bang right into your brain, turns on. It's like flicking a switch and your brain starts working a lot better.”
