I'm doing some analysis about the body deriving energy from ketones vs glycogen. I'm looking for data about how much more/less (I'm guessing less) ketone use is vs glycogen in terms of oxygen consumption. I know our body's RQ when running off fat (i.e, ketone bodies) is .70 vs 1 on glycogen, but how does the cycle look? How do ketones actually turn into ATP? How much oxygen is consumed in that process?
