I've read some interesting news about how people giving people with Alzheimer given a regular dose of coconut oil, maybe due to also some findings about how this could be related to a type 3 diabetes, maybe the lack of ketones in the blood, maybe the brain needs alternative energy sources, or the fat provided by those foods provides a nutrient pathway that is currently dormant or unblocks the neuronal damage in their brain. I'm not any kind of expert, but I've been reading about people who gained some benefit / therapeutic value from doing that. Saw someone post this which was interesting, https://www.ncbi.nlm.nih.gov/pubmed/24244584 so the claim is, maybe damaged metabolism using glucose, and the body needing to switch to ketone, but if someone has a compromised metabolism, say being insulin resistant, this practically shuts down ketone distribution, it also can be found to have heart implications for the future, but if the brain switches to needing fatty acids, and insulin prevents this, it might help understand how Alzheimer progresses and gets worse over time.
