I did a little experiment...last night I did not eat supper, really. I bit of yogurt. I just wasn't hungry. This morning, I headed out for my commute as usual with no breakfast. It was one of my fasted commutes yet.

This is not to say that I'm going to make a habit of not eating supper. It just shows that in my particular case, I seem to have enough fuel to ride my commute without needing much. I was hungry when I got to work, though!
