What does a world-class swimmer eat? In a tweet on Monday, U.S. olympian, Ryan Lochte, gave his shocking answer.

The athlete, who has five Olympic golds, three silvers and three bronzes, gamely showed a photo of his 10,000 calorie meal, possibly composed of "30 asparagus stalks, about 30 pieces of meat and an entire tray of lasagna," Newstalk reported.

In 2010, he told ESPN that he ate a lot of McDonald's in the 2008 Beijing Olympics, "breakfast, lunch and dinner." He claimed he was "comfortable" and was conscious about any setback it would cause. However, he also said that he did not eat products from McDonalds as often, only "once every two weeks." The Twitter photo could only mean that he now takes his Olympic diet seriously.

"I didn't really think that knowing what you put in your body actually had an effect," Lochte, the "born-again health nut," told USA Today.  "So when I was growing up, I was eating fast food every day. I'd drink soda non-stop, candy, just everything. It was horrible. My go-to was McDonald's, for sure."

A 2012 CBS Local report said the secret to Lochte diet is "protein, protein, protein." He would consume 1,677 calories at 6:00 A.M., 504 three hours later, 556 at 11:30 in the morning, 1,370 each at one and four o'clock in the afternoon, and 504 at 7:00 P.M.

While most people cut back on their caloric intake, athletes like Lochte have to consume more food to compensate for the high amounts of calories they burn during training.

Michael Phelps, for example, "starts the day with a hearty breakfast consisting of three fried-egg sandwiches, three chocolate chip pancakes, a five-egg omelette, three sugar-coated slices of French toast, and a bowl of grits (maize porridge).

His lunch doesn't get much smaller as he devours half a kilogram of pasta (enriched with vitamins and fibre) over lunch, two large ham and cheese sandwiches covered in mayonnaise and gallons of energy drinks," The Daily Mail noted.
