Physiology & Medicine / During exercise, when does the body burn sugar and when does the body burn fat?

Hi,
I heard on another PodCast that during the first 20 minutes of a cardiovascular workout, like running, the body is burning off only blood sugar. It is not unitl after the 20 minutes that you start actually burning fat. I don't know if this is true. However, if it is, does that mean that if you run in the morning before eating, that you burn fat sooner, since the blood sugar is probably lower?
I'd love to hear back from you. The show is great!
Thanks for all your knowledge.
