Interesting to see this thread pop up again. I thought I'd update again. I mentioned playing with intermittent fasting, but in the end I returned to what I call three squares, 3 good high protein/low carb meals with minimal to no snacking. If I do snack late at nite, I eat lean protein like canadian bacon. On the bike I still use my muscle milk lite to drink, and nuts for long rides, no more pretzels. I find as long as I keep my blood sugar in a narrow range I feel good on or off the bike and my weight is stable/normalizes. My latest exercise regime is to swim laps during lunch, so for that I need a good breakfast, and/or an early lunch. Basically a high protein meal ~1 hour before I exercise. Then I do club bike rides on the weekends. The mid day exercise is also very good for controlling my blood sugars.

I also find the Livestrong MyPlateD a great place to track food intake, exercise and blood sugars.
