Eat or not before swimming in Early Morning?

Thanks, I didn't know there was an earlier thread on this. However this thread is slightly different. The previous thread simply asks what each person eats. I would like know what science says :) . Some factors to be considered: -Swimming immediately or too soon after eating is not good (for digestion and maybe other reasons). But I doubt anyone who gets up at 5am would wait an hour after eating to go swimming. :cool: -If you don't eat anything, will the high intensity swim deplete your muscles (if you don't have too much fat)? I seem to have read somewhere along this line. -One of the wikiAnswers linked by a post in that previous discussion says that even if you eat shortly before swimming, your energy would still come from what was already in your digestive system, rather than what you had just eaten. Not sure if this is so, but possible.
