The "normal" glucose patterns are almost all based on people following a three-meal-a-day diet. The circadian rhythm is altered by a different digestion pattern, and I think the glucose responsiveness is too. The dawn phenomenon (rising glucose in the morning with no food intake) may be enhanced in some people on a Fast-5 schedule with a late window. There is simply not enough data at this point to offer very firm advice on what's best for an individual. I trust that the body knows what it's doing and the mid-to-late afternoon eating most closely mimics what it has adapted to. The dawn phenomenon coincides with a morning surge in cortisol and may be the body's way of making fuel available for high demand -- unfortunately, we seldom put much demand on it.
Fortunately, you have the means (with some discussion and help from your doctor) to find out for yourself what's best in your case. By checking blood glucose levels several times a day for a few days after you've adapted to one window, you can see how your body responds to one schedule or another. The same goes for HbA1c, but since it changes so slowly you'd have to keep up the same schedule for a couple of months to get a useful HbA1c value.
Because the circadian rhythm takes several days to adjust, I think you have to keep up a given schedule for at least 2-3 weeks before doing a couple of days of regular (every few hours) testing.
I hope this helps --
