Cool, my own anecdata matches yours. I also tend to have a daily fast until well into sundown, consuming only fresh ginger tea with lemon during the sunlit hours. Albeit sometimes if I'm truly famished I will eat something light (banana, baby carrots, etc) but it doesn't happen often. Been basically doing this pattern for 2+ years, and I definitely notice my mind staying clearer during the fast, and I am in the best physical condition of my life, running faster times and lifting heavier weights than ever. Those interested should check out "the warrior diet", which seems to suggest following a similar feeding routine.
