Every athlete has a diet that works for them, but being healthy and fueling their body is key to their success. There has been a growing number of athletes who have moved to a more vegetarian or vegan lifestyle. Many of the athletes who have made the diet and lifestyle change now swear by it. This is not an easy change as professional athletes need to work with nutritionists to ensure they have the proper balance in their diet that would enable them to maintain their physique and to maintain a high level of performance for their sport. In fact a study published in 2015 in the American Journal of Health Promotion found that a plant-based diet can boost physical health and emotional well-being. As the lifestyle change has brought positives to many of the athlete's lives they often share recipes etc. with their fans and teammates.
