Yes, various fasting periods are part of the protocol I'm using to keep ketones high, minimize insulin, and minimize systemic inflammation. I'm also using anti-inflammatory herbs and regular sauna.I've found that fasting has been the game-changer for my neurological condition. I've settled on one 24 or 36 hours fast once per week, and a 72 hour fast once per month. I feel like I've awoken from a flu that lasted for months on end.
Systemic anti-inflammatory medicinal herbs have also helped - Chinese skullcap, Japanese knotweed, and lots of Rhodiola and Siberian Ginseng. I'm also introducing more consistent Tongkat Ali for testosterone levels.
Interestingly Dr Boz goes through long periods of weekly 72 hour fasts - her numbers are excellent and she presents them every week (tues eve live on YT).
One thing I didn't mention above is that I did a 7-day dry fast (no water) according to August Dunning:
By the close of the fast, neurological symptoms disappeared - they resumed slowly after restarting food.
