It's the off season and this is the best time to start losing weight and learning how to keep it off. And in that attempt I was just doing a bit of research reviewing nutrition, when I came across this site and thought I'd share. Parts may be techinical to some but the point is well made of how we uptake glucose into our muscles. Here is the link:

Bottom line for all us triathletes are something like this (in general) eating high glycemix index foods (testing your body to see what works best for you) is important during workouts. High Glycemic Index (GI) food is needed so that the insulin keeps charging into the bloodstream and promoting the body to suck up the sugar/glucose that the muscles need for the workout. If we bonk, it just means that we do not have enough glucose in the blood for the muscles to work. Once the muscles have depleted most of their stores from the workout they need to be replenished.

Important for us as athletes, and this has been said over and over on this thread and many others, immediately post workout, within that "30min." window, we need high GI foods to raise the insulin and get that spike so that cells replenish/take up the sugar lost during workouts. This provides the necessary glucose lost my muscles and organs used during the workout. As the web page explains, the insulin rush makes the body soak up the carbs/sugars/glucose required to replenish muscle glcogen levels. Protein is also very essential for rebuild and recovery after the workout. Basically, all the rest of our days should be spent eating low GI foods to make sure we maintain stable levels of glucose, avoiding that "insulin spike", so it doesn't end up being turned into fat.
