Ketones and the Aging Brain — KETONUTRITION — Glucose is the predominant fuel for the brain, but cannot supply adequate fuel to the AD brain, putting the brain at risk for starvation and exhaustion. However, when ketones become available, the brain will preferentially take up and utilize them as fuel, even in the presence of glucose. www.ketonutrition.org
So what happens basically is that Ketones fuel your brain so much better than glucose and in many cases may be the only source of fuel for people who’s brains can’t make use of glucose. This helps explain why there has been a flood of anecdotal cases of improvement for people with Alzheiimers that have drastically improved by adding coconut oil, MCT, and C8 oil to their diet.
