I was thinking more in terms of glycogen and lipid getting burned up during exercise. Whatever glucose you can't use gets converted in one way or another. I'm sure there are nuances, and it's been a while since I had to be able to recite the TCA pathway, but isn't fructose converted to glycogen? So, can't it be burned for energy like anything else? It's one of the metabolites for the TCA cycle, right? Not to mention, this article (and this thread) are all playing fast and loose with all sorts of scientific terminology... :)
