Lionel Messi's two decades at the top of world football are often credited to his supernatural talent, but his longevity is also a story of disciplined reinvention. In 2014, facing a string of muscle injuries that threatened to shorten his prime, the Argentine star made a radical change: he handed his diet to Italian nutritionist Giuliano Poser and never looked back.
The turning point: Poser's intervention
In his early years at Barcelona, Messi ate like many young Argentines—milanesa, fast food, and sugary drinks were staples. His brilliance masked the toll, but by the early 2010s, recurring injuries and visible fatigue on the pitch signaled that something had to give. At the suggestion of international teammate Martín Demichelis, Messi sought out Poser, who designed a plan built on five pillars: clean water, high-quality olive oil, whole grains, fresh fruits, and vegetables.
Processed foods, refined sugars, and excessive red meat were sharply reduced. Perhaps most notably, Messi swapped sodas for yerba mate, the caffeine-rich South American herbal infusion loaded with antioxidants and vitamins. The results were immediate: in the 2014–15 season, he scored 58 goals and added 23 assists, leading Barcelona to a historic treble—La Liga, the Copa del Rey, and the UEFA Champions League.
Simple recipes, balanced indulgence
Poser's approach wasn't about deprivation. One of Messi's go-to dishes is a simple roast chicken with root vegetables, garlic, onions, leeks, and olive oil—a meal that Barcelona's official channels once highlighted. But the World Cup champion also admits to a sweet tooth, indulging in chocolate, dulce de leche, and ice cream on occasion. This balance, he says, is key to sustaining the physical and mental demands of elite sport.
The diet overhaul has paid off in longevity. Now in his late thirties, Messi continues to perform at the highest level, recently notching his 101st goal for Inter Miami and still chasing records like Marcelino Carioca's free-kick mark. His ability to adapt—both on and off the pitch—has become as defining as his dribbling.
For young players across Latin America, Messi's story is a lesson in professionalism. It's not just about talent; it's about making the right choices when it matters most. As he prepares for what may be his final Argentina match, his dietary discipline remains a cornerstone of his enduring greatness.
