Is there any harm if you don't eat anything before swimming at 5am, 6am (though I suppose that's what most early swimmers do)?

In an exercise phys. class i took recently we were taught that the food you eat the day/night before is what you are using for energy the next day. The food you eat right before a workout will not be used by your body until later on in the day.
If you take a blood sample in a fasted state, drink a high glucose beverage, then take a series of blood samples, what happens to the blood glucose?
I agree that the food you ate several hours ago or more provides the stored energy, but you can dump energy into your blood stream almost instantly via your stomach.
