Cristiano Ronaldo, the renowned footballer, has adopted a strict diet that excludes milk, which he believes is unnatural for human consumption beyond infancy. His former private chef, Giorgio Barone, emphasizes that humans are unique in drinking the milk of other animals, and this practice is not found in nature. Ronaldo's diet is well-structured yet balanced, featuring healthy foods such as avocados, eggs, chicken, fish, and a variety of vegetables while completely avoiding refined sugars and flour-based carbohydrates. This disciplined approach has allowed him to maintain body fat levels below 10% and stay in peak physical condition as he enters his 25th professional season. Additionally, Ronaldo incorporates recovery methods like saunas and ice baths into his routine, further supporting his longevity and performance in the sport.
