Phelps is apparently in a different zone:

Breakfast of Champions

Phelps lends a new spin to the phrase "Breakfast of Champions" by starting off his day by eating three fried-egg sandwiches loaded with cheese, lettuce, tomatoes, fried onions and mayonnaise.
He follows that up with two cups of coffee, a five-egg omelet, a bowl of grits, three slices of French toast topped with powdered sugar and three chocolate-chip pancakes.

At lunch, Phelps gobbles up a pound of enriched pasta and two large ham and cheese sandwiches slathered with mayo on white bread - capping off the meal by chugging about 1,000 calories worth of energy drinks.

For dinner, Phelps really loads up on the carbs - what he needs to give him plenty of energy for his five-hours-a-day, six-days-a-week regimen - with a pound of pasta and an entire pizza.

He washes all that down with another 1,000 calories worth of energy drinks.

That's 12,000 calories a day--six times what the average man should have.
