Leo Messi made drastic changes to his diet in order to rekindle his best form, according to his personal nutritionist Giuliano Poser.
The Argentinian suffered a number of injuries last season and, despite winning the Golden Ball at the World Cup, was considered below his usually brilliant best in Brazil.
With Cristiano Ronaldo easily sweeping the Ballon d'Or for 2014 and Barcelona facing a disastrous season under Luis Enrique, Messi knew he would have to refocus his efforts to return to the pinnacle of football.
According to Poser, this began with totally eradicating processed foods from his diet, replacing them with a number of high quality wholefoods instead.
"After the World Cup maybe something changed," Poser told La Gazzetta dello Sport. "Messi has probably realised that he could change something.
"Leo is a humble guy. He won everything but he still wants to continue to excel for many years.
A humble man
"He understood that to do so he had to change something. Leo had the humility to try to do something different in his professional life.
"It is from January going strong, with the exception of the three weeks following the Clasico with Real Madrid on 22 March when he suffered a bruised foot,' Poser tells the Italian paper.
"He changed his diet: no more processed food and he replaced it with foods rich in vitamins, minerals, fibre contained in whole grains, fruit, vegetables, fish and olive oil."
The result was clear for all to see. His form for Barcelona returned to its very best and he finished the season top of both the scoring and assist charts at the Nou Camp.
Not only were his individual stats impressive, but he also scooped his second treble as a Barcelona player, inspiring the club to the La Liga title, a Copa de Rey and a Champions League trophy.
Messi finished the season with 60 goals in 59 matches as well as 28 assists in all competitions and is almost certain to win his fifth Ballon d'Or next January.
However, he will first attempt to win the Copa America with Argentina, a title that has so far eluded him in an otherwise incredible career.
Argentina are the current favourites to seal the trophy ahead of a Brazilian team in transition and the hosts Chile.
Will Leo Messi inspire Argentina to a Copa America triumph?
