You'd think professional athletes like Peyton Manning would be sensible when it comes to what they eat, especially before a big competition. But, there are those who would make junk-food junkies proud. So, before you decide to eat the way the pros eat, you really should know what they eat.

As expected, Peyton Manning of the Denver Broncos makes some pretty healthy choices when fueling up for game each week.

Former Chicago Bears linebacker Brian Urlacher was the complete opposite.

Then, there are those like the 'fastest man on earth,' Usain Bolt, who make you wonder how he can win considering what he eats before a race.

Personally, I'm all for the Brian Urlacher diet. But I'm sure, even though he's retired from the NFL, he probably doesn't exist on chocolate chip cookies alone.
