Novak Djockovic surprised the world with an impressive tennis performance year round. What he did to reach this excellence level in performance was not changing coach, conditioning trainer, racquets or 
anything related specifically with tennis; all he did was change what he eat! That’s the biggest argument he used to write his book “Serve to Win: The 14-Day Gluten-Free Plan for Physical and Mental Excellence”.
Inside the pages, the reader makes a quick trip to Djockovic childhood and teenage years, learning a little bit about him before dropping the bomb. Djockovic tells the reader how he managed to make a transition to a gluten free diet, and how that small change helped to become an extraordinary tennis player. Here is a sample of the extraordinary level of athleticism he achieved.
Can gluten really have that much weight in our everyday activity? The answer is yes, but not for everyone. In the particular case of this book, a gluten free diet helped an elite athlete to reach a higher level of performance, but he also gives the example of how people that don’t have as demanding physical activity can be benefited by this type of diet.
There is a lot of research going on about the impacts of gluten in a diet, and it is worth mentioning this is not a diet for anyone, because gluten is everywhere and acquiring products without this substance turns out to be an expensive quest in the grocery store.
