Lionel Messi has benefitted from a new diet during his 14-15 season that will almost certainly result in another Ballon d'Or.

Nutritionist Giuliano Poser confirmed working with Messi on what he puts in his body.

In an interview with Gazzetta dello Sport, picked up in AS, Poser, from Argentina, said Messi had taken a tip from his international colleague Martin Demichelis and consulted him.

"I am a good friend of Demichelis and he recommended he [Messi] visit me," Poser said. "After the World Cup, something changed. Messi had the intuition and humility to try and do something different in his professional life."

The 59-year-old kinesiologist, whose methods reportedly include the use of Bach flower remedies, emotional therapy and a balanced diet, said the change from processed to natural foods had allowed Messi to train with greater intensity.

"He eliminated processed foods and replaced them with foods rich in vitamins -- cereals, vegetables, fish and olive oil," Poser explained.

"He had won everything, but wanted to continue this excellence for years and understood he had to change something. We are talking about a very intelligent and intuitive person."
