In Serve to Win, Djokovic recounts how he survived the bombing of Belgrade, rising from a war-torn childhood to the top tier of his sport. He also reveals the diet that transformed his health and pushed him to the pinnacle.

While Djokovic loved and craved bread, pasta and the pizza from his family's restaurant, he discovered that his body couldn't process wheat.

A player once plagued by aches, breathing difficulties and injuries on court suddenly became the number-one tennis player in the world simply by changing what he ate. Eliminating gluten made him feel instantly better, clearer, lighter and quicker. His new physical health and mental focus enabled him to achieve his two childhood dreams: to win Wimbledon and to be ranked the world's number-one tennis player.
