Exercising without eating first can lead to low blood glucose, which can interfere with your brain function. When you eat, glucose levels in your circulating blood rise and are available to travel to your muscle cells. Glucose is also available as glycogen stored in your muscles.
The simple fact of the matter is that after eating your body diverts blood flow to your stomach and intestines to digest and soak up the goodies in your food. If you try to exercise too soon then your body won't be able to cope with the increased requirement of blood to the muscles as well.
