Ketones are a preferred fuel for the brain and are associated with improved cognitive function.

“and that's because ketones are one of the brain's preferred fuels for cognitive work. In fact, ketones have been shown to be associated with four brain function, which is associated with context switching focus and formulations of strategies, etc. All the sorts of things that are important for doing deliberate focused work or physical performance.”

“personally at an anecdotal level I like the way my brain feels on ketones way more than glucose I I liked when this car runs on ketones again it may take me some time to readjust the glucose if I introduce the carbohydrates but I feel a difference there and many people report that with ketogenic diet at least anecdotally”

“Ketones provide an essential "alternative fuel" for the brain under these challenging conditions, effectively rescuing cognitive function and alleviating deficits.”

“But I think in the context of, like, aging and a context of traumatic brain injury or pathology, I think the brain will really prefer to use ketones because...or in the context of some kind of stress hypoglycemia or something like that, I think the brain will also prefer to use ketones.”
