Mike Tyson kept things simple when it came to dispatching his opponents - and the same was true of his diet.
The American legend insists he is retired for good after a brief comeback against Roy Jones Jr in 2020 following a sensational career in the sport where he once reigned as undisputed heavyweight champion. Tyson has since remained in incredible shape, regularly showing off a ripped six-pack in the gym.
And when he was at his peak, Tyson's diet consisted of around 4,000 calories-a-day which included three large meals with regular snacking. But compared to the diet of today's heavyweights Anthony Joshua and Tyson Fury, it was somewhat plain and boring.
