Ryan Lochte Why Has He Improved So Much?

At an interview with eurosport television, the gold medal swimmer was asked what was the major difference between the 2008 Olympics and this year? He attributes most of his improvement on cleaning up his diet. Up to the 2008 Olympics he would eat McDonald's 10 days straight, but since cleaning up his diet, he feels much faster. Just another example of good in=good out. (real scientific there).
