London, May 13 (Inditop.com) Former world boxing champion Mike Tyson, who once bit off part of Evander Holyfield’s ear during a fight, has now become a vegetarian.

Tyson, 43, said he has given up animal products in exchange for a purely vegetarian diet, reports dailymail.com. And it seems the change is doing him some good. After piling on the pounds in recent years, Tyson looked fighting fit as he headed out for dinner in Beverly Hills recently.

Tyson was the youngest man to win the heavyweight title. He won it when he was just 20 and after the victory he earned the nickname ‘Iron Mike’. He quit boxing in June 2005 after losing a match against Irish boxer Kevin McBride.

Tyson is known for controversies in and outside the ring. His career took a battering when he was convicted of raping beauty queen Desiree Washington and served three years in prison.

He married three times.
