World number one Novak Djokovic will release a cook book before the US Open next month.

Djokovic, who lost to Andy Murray in the Wimbledon final earlier this month, has attributed much of his success to a 'nutrition-based performance guide' first adopted in 2010.

Now the 26-year-old Serbian will share his culinary secrets with his fans in a book called "Serve To Win".

"Finding the right foods for my body has made me lighter, healthier, and more focused," Djokovic told reporters. "It's made all the difference in my career and in my life."

Djokovic has won seven career Grand Slam titles, the last of which came at the Australian Open in January where he beat Andy Murray.
