When you deprive your body of food in the morning, after having not fed it since dinner the night before, the body goes into protection mode, to ward off what it interprets as potential starvation. So the metabolism slows down to conserve what energy it has. When this happens, EVERYTHING is working slower. Our digestive system, our brains....etc. (YOU, Michel, might be a little scary if your brain was working at full tilt)
Studies have proved time and time again, that children who eat breakfast do better in school.
