After reading the story on Anthony Famiglietti from Universal Sports, I thought it was a little strange the conclusion he came to about his diet. If he could have an extremely successful career spanning a decade with the diet he described, why did he decide it was his diet that was responsible for poor performances? It sounds to me like he was simply exhausted and needed to rest (which he did). If his diet was so disasterously unhealthy, he wouldn't have been able to perform so well year after year. Sure, he's had a steeple p.r. since he change his diet (and atitude, and rest habits), but it wasn't a huge p.r., so makes you wonder how significant any change to his diet could have affected his performance.
On a side note, this story makes ridiculous those folks who swear that McDonald's, pizza, fast food, etc. are poison. How could one of the best runners in the country eat this stuff nearly exclusively if it is poison? How could Tyson Gay eat at McD's during the World Championships and come away with 3 medals?
