I drink chocolate milk, usually about 1 hour in. After the exercise is complete, a real meal is exactly what you need. No arguments there at all. While you're training someone(or yourself) for any type of endurance event(eg triathlon), it's not uncommon to toss them a sugary(decaffeinated!) soda or juice. You're goal is to make sure they never exhaust that available supply of glucose until the event is complete. If they do, along with cannibalizing their muscle mass, they're going to have short-term discomfort(cramps, mental fogginess).
