The diet of performance athletes

Here is Michael Phelps' dietary regimen during the Olympics:

For breakfast: three fried egg sandwiches, with cheese, tomatoes, lettuce, fried onions and mayonnaise, followed by three chocolate-chip pancakes; a five-egg omelette; three sugar-coated slices of French toast and a bowl of grits (a maize-based porridge), washed down with two cups of coffee.

For lunch: half a kilogramme (one pound) of enriched pasta; two large ham and cheese sandwiches on white bread smothered with mayonnaise, washed down by energy drinks.
