JP is one of the greatest examples of how you can be smart in one narrowly defined way, and an absolute dipshit in so many others. I never really bothered with the guy as the subject doesn't interest me all that much, but I hear he was a leading voice at one point, and a fairly coherent one at that. And then based on his early success and subsequent fans, he let it get to his head and started thinking he was the smartest guy in every room.

Another example is Steve Jobs. Autistic rainman style levels of design, marketing and usage knowledge, but apparently couldn't do simple shit like feed himself properly or maintain his personal hygiene.

TBF, scientific studies seem to support that ketosis can influence/mitigate neurological conditions. The ketogenic diet was originally developed as a method of managing epilepsy, for instance.

The "classic" ketogenic diet is a special high-fat, low-carbohydrate diet that helps to control seizures in some people with epilepsy.

Personally, I'm giving it a try to assist with migraine management, per this study:

In total, 17 patients (73.9%) reported a reduction in the headache days, and 15 patients (65.2%) reported a reduction in headache days of at least 50% and were considered as responders.

The study itself had 23 patients iirc, so I'm sure more research needs to be done, but I'd like to avoid daily medications due to some of the undesirable side effects and I'm in good enough health to accept the risk for a few months.
