From my end your guess adds up. I did exercise, and my body's transition to increased affinity for ketone utilization was definitely noticeable during my workouts. And indeed the mental clarity and color enhancement was more pronounced following a workout, however unlike on a normal diet, these state stayed with me all day rather than only for a few hours. > Glucose is fuel for the brain, but fat isn’t...ketones are which are a by product of fat burning, so the more fat burning/ketones the more fuel for the brain. That definitely makes sense to me and would even to a certain extent explain the difference between individual experiences with ketogenic diet.
