Yes I have been doing Paleo for the last three months, though I thought after 12 hours without eating your body goes on ketosis automatically but I may be wrong.
I have heard the boost that ketons provide to the brain functionality. I also found this article very interesting where they show that hunger improves strategic decision making:

During my IF, I was eating 2,5k calories right after the gym in a 4 hour time frame. I felt asleep for the next 5 hours or so, being unable to play during those hours.
I am thinking about doing two big meals after finishing my poker session and right before going to sleep. I am curious about how that could affect my mental game while playing given the hypothesis that being hungry improves our decisions.
