Chhetri says, "I have become vegan -- I don't take dairy or meat. It has helped me a lot in terms of recovery and digestion" A growing of elite athletes all over the world, from Lewis Hamilton to Novak Djokovic, Patrick Baboumian to Venus Williams have adopted a vegan diet, and all of them have praised plant-based diets for helping improve their performance. IGF-1 Growth Hormone, Muscle Bulk and Plant-based Diets IGF-1 or Insulin-like Growth Factor Oneis a human growth hormone. It is responsible for how 'big' you become. IGF-1 in mother's milk stimulates growth of her baby's body. Once we grow up, though, excess IGF-1 taken through diet in meat and dairy foods may contribute to wrong kind of 'growth', stimulating the growth of cancer cells. Fortunately, plant-based diets reduce the amount of IGF-1 in your blood, thereby reducing cancer risk.Some people believe that lessIGF-1 reduces muscle bulktoo. Research has shown that this is untrue - for example, people with unusually high IGF-1 levels suffer from acromegaly, where the bones grow large, but muscle bulk does not change. Even when you take IGF-1 injections, it does not seem to improve your muscle bulk or even bone strength. Gladiator Diet for Muscle Strength Who better to study than people who trained for one purpose, and one purpose only - to be the strongest and fastest possible human being? Roman Gladiators were called the 'Barley Men' for a reason. It may surprise you to know that traditional gladiators did not consume meat, fish, eggs or dairy products, but instead consumed a plant-based diet!Archeological studies that assessed the carbon, nitrogen, and strontium isotopes in unearthed gladiator bones found that they ate a mostly plant-based diet. Interestingly, the legionnaires of the Roman army also ate am almost exclusively plant-based diet based on wheat and barley.Even today, in Kenya and Ethiopia, which have a track record of having the best long distance runners, athletes eat a 99% plant-based diet. Plant-based vs Meat-based Diets for Athletic Performance Short term interventional trials show no significant difference between meat-based diets and plant-based diets for endurance, muscle strength or performance. Yes, if you are an athlete, you are primarily focused on performance. But think about this - if meat-based and plant-based both work equally well for performance, and plant-based diets can also protect you from diabetes, high blood pressure, heart disease, and cancer - which are the leading causes of death among athletes, which one would you choose?
