Before he conquered Rafael Nadal on the Wimbledon Championships grass courts Sunday, Novak Djokovic beat out another worthy opponent: pizza.
The Serbian pro tennis player, 24, who secured his champion title with a 6-4, 6-1, 1-6, 6-3 win over Nadal, has cut out food containing gluten, including pizza, pasta and pretzels, from his diet.
Last year, Djokovic's nutritionist found out the athlete was allergic to the protein, which is found in common flours, reports The Wall Street Journal
. Since, he says he feels much more confident on the court.
And it shows: as of Monday, he was already guaranteed to take over the No. 1 ranking from Nadal.
"He has massively improved his serve, his fitness, and he's hitting his forehand a lot better," Brad Gilbert, ESPN commentator and former coach of Andy Murray and Andre Agassi, said of Djokovic prior to Wimbledon. "I've never seen anybody move better on a tennis court in my life."
