Michael Gerard Tyson is an American former professional boxer who competed from 1985 to 2005.
In 2005, when he retired, he regularly consumed meat, alcohol and drugs. Four years later, doctors diagnosed him with obesity, breathing problems, high blood pressure and arthritis. A year later, he changed to a plant-based diet.
Now he says he is in the best shape ever. And it is said that it is not excluded that he would return to the ring.
