I am angry I wasted time on this, it feels like I've eaten a processed meal for the mind. It started to go off the rails for me at the description of insulin's effect on weight. He seems to upend everything all the doctors I follow say in that part, then provides very little commentary to back up his claims. The chapter on sugar should've had so much more info given that sugar is what all the experts say is the culprit. He doesn't address that at all; he talks about tooth decay at length instead. I'm really frustrated and disappointed with this book.
