At age 20, Tyson became the youngest heavyweight champion in history in 1986 and went on to have a lucrative, albeit controversial, boxing career until 2005 when he retired after losing to Irish boxer Kevin McBride. In 2010, Tyson—who had a habit of eating steak prior to fights—adopted a plant-based diet in an effort to alleviate health issues associated with drug use. 

“Well my life is different today because I have stability in my life. I’m not on drugs. I’m not out on the streets or in clubs and everything I do now is structured around the development of my life and my family,” Tyson told Oprah in 2013. “I lost weight. I dropped over 100 pounds and I just felt like changing my life, doing something different, and I became a vegan.”

Last year, Tyson reaffirmed his commitment to veganism to GQ Sports. “I don’t eat anything that has a mother and father. If you were created through a mother and father, through any kind of intercourse, I won’t eat you,” Tyson said. “So that means I only eat vegetables and stuff.” 

This week, Tyson launched Legends Only League, a new venture that helps older legendary athletes return to the sports at which they excelled.
