I also believe that timing has a minor role in the whole picture of getting things right. I also try to most of my carbs pre and post-workout, so that at least I will have maximum energy levels to maintain a high(er) intensity than without a proper meal. I've done fasted workouts too, but I just feel better when I've had a proper meal pre-workout. (Not mentioning the mental enlightment of a good post-workout meal after a heavy workout

) It might be a mental thing, but it works for me so that's fine for me.
