I think how hard you ride has a lot to do with it. If you're riding at a
pretty easy pace, your body is able to keep up with your energy needs by
converting stored fats. But, at higher intensities and longer efforts, your
body burns mostly stored glycogens (carbs), and has a hard time keeping up
with demand unless you take some more carbs on board during the ride.
