Something interesting here:
What Michael Phelps eats in one day
His typical breakfast as a teenager: Start
with three sandwiches of fried eggs, cheese, lettuce, tomato, fried
onions, and mayonnaise; add one omelet, a bowl of grits, and three
slices of French toast with powdered sugar; then wash down with
three chocolate chip pancakes.
His average daily intake of calories? 8000 to 10,000 calories
per day.
Okay..... who here wants to challenge Michael Phelps to a
Kuishin-Bo deathmatch? 
He can get away with that only because of his insane training
schedule
