Novak Djokovic to release nutrition-tips book before US Open 2013

World number one Novak Djokovic will finally be sharing a bit, if not more, of his secrets to success on tour via a book containing nutrition tips. The Serbian star has always attributed his surge in the past few years via a change of diet regimen.

The book is titled “Serve To Win,” which is the top-ranked player’s “nutrition-based performance guide.”

Djokovic’s headline-grabbing gluten-free diet which he underwent since late of 2010 has become a key to his success on the men’s tour. He’s went on to win an additional five Grand Slam titles since his solitary win at the Australian Open in 2008. In 2011 alone, Djokovic won three out of the four Grand Slam titles, having only fell short at Roland Garros where he reached the semifinals.
