What is the title of Djokovic's 2013 nutrition book?

The title of Djokovic’s 2013 nutrition book is Serve to Win. Its full title is Serve to Win: The 14-Day Gluten-Free Plan for Physical and Mental Excellence.

The book presents Djokovic’s account of changing his diet after identifying that gluten affected how he felt and performed. It combines autobiography, eating advice and training-related guidance, connecting his food choices with his rise to the top of professional tennis.

Djokovic’s dietary story became widely associated with his 2011 breakthrough season, when he won three Grand Slam singles titles and spent much of the year ranked No. 1. The book was published after that breakthrough and helped make his nutrition routine part of his public image.

A common mix-up is to treat Serve to Win as a conventional tennis autobiography. It does include personal history, but its central subject is the relationship between diet, physical preparation and performance. Winning Ugly, Rafa and Open are tennis-related book titles, but they are not Djokovic’s 2013 book.
