-- To be an Olympian, you need to eat more than just the breakfast of champions. You need to eat like a champion for every meal, but the number of calories ingested by the world's top athletes can vary widely.
Take a look at the different foods and caloric intakes that fuel these competitors.
Kerri Walsh Jennings:
Before Walsh Jennings took to the sand to face the Swiss in the Volleyball Match, she likely turned to her old standby of almond butter and honey sandwiches.
For Bolt, his go-to is chicken nuggets and wings -- in the morning. It’s a good thing there is a 24-hour McDonald's in the Olympic Village, which is free for athletes. And his secret ingredient to success is reportedly yams. His total daily calories total 5,500.
America’s gymnastics darling considers almonds and dark chocolate her indulgences. Otherwise, she tends to stick to lean proteins and vegetables for a grand total of 2,000 calories a day. In contrast to Bolt, this is much more aligned to health officials’ recommended caloric intake of 2,000 for women and 2,500 for men.
Gold medalist Ledecky keeps her dietary regimen pretty simple, telling CBS News in September that she eats "Whatever my mom makes me."
