David "The Hayemaker" Haye is a British professional boxer and widely recognised as one of the best boxers of his generation, boasting a 86.2% knockout ratio. He’s one of only two boxers to become a unified cruiserweight world champion, winning three out of the four major world titles in 2008 as well as The Ring magazine title. He then moved up to heavyweight and became the WBA champion in 2009 after defeating Nikolai Valuev, who had a world record 11 inches and 7 stone advantage on Haye. After a three and half year hiatus, he returned to the ring in January 2016, at the age of 35, to knock out Mark de Mori in 131 seconds.
Haye became vegan for ethical reasons in 2014, and launched his own range of vegan protein. He told the Telegraph in January 2016 that the diet has made him better and stronger than ever.
“What’s the closest relative to a human? The ape. They’re 20 times stronger than man but they’re predominantly vegan”.
