What if you're non-biological entity that resides at Shady Acres?
Seriously though, in my youth, coaches used to ride our asses not to eat after dinner, with a light breakfast on game days. (They owned you from breakfast on game days.) However they thought water was bad for you, even in the at 90 plus degrees w/ high humidity. If you started looking wobbly they would give you salt pills w/ just a few sips of that evil water, have you jog the sideline after you were steadier, and send you back in to butt heads with the guy lined up the length of the football from you. I'm surprised more guys didn't die from heat stroke, but air conditioning wasn't as common then, guys were used to the heat.
Eating that way wan't a bad way to go, but you had a tendency to get fat after your playing days were over as your body still craved the same calories as before but didn't work them off w/ three hours of hard, high energy workouts.
