There’s good reason that Swiss champion Roger Federer is a phenomenon on and off court. From a brat who used to throw his racket around every time he lost a match as a child, he has matured into a sporting superstar.

He has evolved into an elegant, graceful, hard-working tennis professional. His diet will be just one factor. It’s not all healthy and Federer is known to have a sweet tooth.

But when he prepares for competition, you can bet that he goes for optimum fuel from foods.

Yet pundits were quick to write Federer off a just few short years ago. Boy, did they get that wrong!
