Peter Attia apologizes for giving the exact wrong advice for most of his career. Thank God that I gave up the conventional wisdom on health. If you are concerned about your health try a low carb diet. I started out with the Primal Diet but I now restrict my carbs to an even greater degree with what is called a Ketogenic Diet. I also try to incorporate intermittent fasting to further lower my blood glucose and increase my ketone production even more. My mind has never felt so sharp and my health has never been better.
