Sam,
Thats a pretty good amount of time to go without eating. I would say by Kentucky Windage standards you are fairly decently fat adapted. Once you reach higher levels you will know your fat adapted because you will have very little body fat. There is two ways to be lean 1) be efficient at burning fat as you are carbs - 1/2 petrol, 1/2 diesel. Or count calories and starve yourself.
What time do you generally
1) Wake up
2) Eat breakfast
3) Lunch
4) Dinner
5) Go to sleep
