Lalitha,
As you can tell from the posts, some do, some don't. I've experimented with this a little myself this year. In the past, I was able to have a complete protein/carb breakfast an hour before my 9:30am workout. I felt great during my workouts which would last for over an hour and half to sometimes, two hours.
: Those were awesome and I miss those days now that I have some time constraints. But just for the record, ya don't need to be at it for two hours. (Just had to add that for clarification)
Currently, I am waking at 4:30am to get to the gym at 5:30am. My last meal is usually around 7:00pm. Because our bodies use stored glycogen during our sleep it is helpful to have a simple carb just before doing the workout. Usually I will have a slice of whole grain toast (okay, not so simple carb) or half of a very ripe banana. It isn't meant to fill me up it's just enough to give me a little something to run on until I have time to eat when I get home. At that time I will have the protein oatmeal goo that I'm so fond of. The bonus is that it's a great post workout breakfast.
I also found this article interesting too:

One of the articles I read suggested that the body does not care if the simple carbs are solid or liquid and suggest that adding a quarter cup of OJ to the water bottle will also help provide you with the energy needed to keep your momentum going during the workout. I like that idea but I still need to have something solid. Just a personal preference.
