Mike Tyson has dropped a massive 100 pounds for his boxing comeback by going vegan.
Tyson, 54, returns to the ring this Saturday when he faces fellow boxing legend Roy Jones Jr in an exhibition bout.
He’s ditched meat from his diet for his return and also spent up to TWO hours on the treadmill after advice from his wife.
Speaking on Good Morning America, he said: “It was difficult, but only for one particular reason: because I had to lose 100 pounds.
“But other than that, I’ve always done this my whole career.”
When asked how he lost all that weight, he replied: “I became a vegan.”
He added: “My wife [Lakiha Spicer] told me to get on the treadmill. So I went from 15 minutes on the treadmill and I winded up ending at two hours.”
And the rules have been laid out which equate to a hard sparring session between the American boxers.
No knockouts are allowed with Tyson insisting he’ll be protecting himself at all times.
He continued: “I’m not trying to knock nobody out, but I’m trying to protect myself at all times.”
Tyson hasn’t fought since 2005 when he suffered a crushing defeat to Kevin McBride.
As for Jones Jr, the 51-year-old last fought in 2018 when he outpointed Scott Sigmon.
