Eating is good, but you've got to watch what you eat. Don't eat alot, and make sure it's complex carbs, preferably with some protein. Biggest thing to remember is to stay away from the simple sugars. Alot of people think they ought to chug a gatorade at this time, but this is horrible. What happens is that a flood of simple sugars will make your
body release a flood of insulin to cover it. Unfortunately insulin blocks off access to your
fat reserves, so basically you have to burn up most everything that's in your blood stream before you can burn anything from
fat, and the worst part about this is that there's a switchover period, as you can't immediately go from fueling off of carbs to fueling off of
fat. Basically you'll feel great... until you burn up all these carbs, but then you'll bottom out, and while your
body is switching
energy sources, you will absolutely feel like crap and have very poor results. This is what people are talking about when they describe a "sugar high and crash". This is also why many marathon runners just forget the pre-race meal altogether and just carbo-load the night before. That way they can be fueling off of
fat from the get-go and bypass that switchover period. If you do eat, just make sure you don't spike your blood sugar so that you can avoid these bad side effects.
