Well, your likely out of fuel after your workout since you haven't eaten anything in 10 hours or more.
I work out in the mornings too but I always try to grab something to eat 30 minutes to an hour before I workout. It's the first thing I do when I wake up, I go down and eat and then come back upstairs and get ready for the day. After I workout I have a whey protein shake. If I don't have time to eat before I workout, I'll have a shake before and after I workout. After you workout your muscles are hungry for nutrients it's important to feed them at this time. But limit fat intake immediately post-workout, I forget why, but it hinders the aborption of protein or something like that.
