The book, described as a ''nutrition-based performance guide," will be released by Zinc Ink/Random House before the US Open tournament later this summer.

Since adopting a "performance-focused" gluten-free diet in late 2010, Djokovic has won six of his seven Grand Slam tournament championships. In 2011, he won Wimbledon and the Australian and US Opens. In 2012 and 2013, he won the Australian Open again.

Djokovic says that his gluten-free fueling has made him lighter, healthier, and more focused. It has, he adds, "made all the difference in my career and in my life."
