1:45.  This shows up in development as well when the neonatal brain is built for a ketogenic environment.  When we knock out ketones or the ability to use ketones in animal studies actually shows catastrophic energy failure despite normal amounts of glucose in the brain cannot develop grow or function in normal ways while it's developing.

2:04.  Pregnancy has also been called accelerated starvation where women who are pregnant get into ketosis far faster as pregnancy advances so when women are in the third trimester it's actually very easy for them to get into ketosis even when eating carbohydrates at levels that would normally kick other people out of ketosis and that's because those ketones freely cross the placenta into the developing fetuses because the brain requires those ketones to function normally and also reconstitute into fatty acids that make up the physical the building blocks of the brain.  And the third trimester especially the brain is growing exponentially needs as much ketones and fat as the mother can provide.  Breast milk also does this as well because breast milk is deliberately ketogenic even children even though there's a high level of lactose in it, they are still producing ketones because their brain requires it.  And Studies have shown that formula-fed babies have far fewer ketones than breastfed babies.  So the default, the human brain is designed to run on fat and ketones and be built from cholesterol, not from constant dietary glucose and seed oils that are very poor substitute for what your brain is requiring.  So your brain is actually built out of cholesterol and animal source nutrition.  Cholesterol works as structural components.  The brain is roughly 2% of the body weight but contains over 25% of the body's cholesterol.  Cholesterol is a rate limiting step for myelin which is white matter insulation and synapse formation.  So this makes the signals in the brain faster and connect to more cells so that makes your brain and nervous system more powerful.  Lower cholesterol means fewer synapses, fewer connections with different cells and impaired brain growth and development of this myelin which slows down conductivity of these signals from your neurons.  

3:54.  Statins have even been shown to be iotrogenic, meaning that they are man-made medical-based cause of harm and can cause neurodegeneration.  So fat soluble statins can cross the blood brain barrier and blunt the brains cholesterol synthesis.  So it prevents the brain from making its own cholesterol which it's made out of.  Whatever you want to say about cholesterol in the arteries and whether or not that leads to arterial sclerosis which I believe the evidence shows very clearly that it does not, you cannot say that the cholesterol made in your brain has anything to do with that because it's passed the blood-brain barrier.  It does not get into the bloodstream in it's not able to cross from the brain into your bloodstream.  So the only thing you're doing while taking a Statin and slowing down your brains production of cholesterol is actually slowing down and damaging your brain.  And this is why the FDA has required warning labels on statins saying that it can cause memory issues, cognition, and other sorts of neurological conditions as well.  There was also a withdrawal and rechallenge study in Alzheimer's patients back in 2012, where they took 18 patients who were on statins who had Alzheimer's and tested their cognition score, then stopped their statins and then tested them 6 weeks later without doing anything else, and they found that their cognition scores improved across
