Not just athletes but also people who exercise better in the morning. I have to head out running before 06:00 ( ex-farm border collie dog still has early-rising demands ) so need to eat about 05:30. On a couple of occasions I overslept and skipped breakfast. It was terrifying, I barely had enough energy to make it back home and was shaking. All my body wanted when I returned was sugar, now. So in my case at least a bowl of museli / milk / yoghurt and a banana is the minimum possible breakfast.
