Mike Tyson has been warned about the importance of maintaining a healthy lifestyle ahead of his seismic showdown with Jake Paul later this year.
It will be the 57-year-old's first fight in four years, having last fought Roy Jones Jr back in 2020.
Tyson has given up sex and cannabis as he looks to beat Paul, with the boxing icon also updating fans with clips of him working in the gym.
Yet former boxing star Vitor Belfort has warned Tyson that, in order to beat Paul, he shouldn't be maintaining a healthy lifestyle for just a few months.

He instead thinks Tyson should have been looking after himself for a long period in order to boost his chances of glory.
Belfort told World Boxing News: “It is good business for both fighters.
"They generate a lot of money for each other, which is good for the sport.
"But only Mike can answer that question. I don’t think it would be a good idea if he only trained for this fight.
"A fighter always has to keep up a healthy lifestyle. I hope that he is.”
Belfort previously fought Evander Holyfield in an exhibition match back in 2021.
Addressing comparisons between that showdown and the upcoming fight between Tyson and Paul, he continued: “When I fought Holyfield, he was very strong and very fit, but I was the better man on that night.
"If he hit me, I could have gone down – that is the nature of the sport.
"However, I hit him first.
“This fight feels more like an exhibition, and I don’t think Mike is the same fighter he used to be.”
Tyson, meanwhile, has also been speaking as the showdown approaches.
And the 57-year-old has revealed he's hoping hypnosis can give him an edge as he looks to wind back the years in two months' time.
“I’m an exponent of hypnosis," he recently told Nick Kyrgios.
"I was raised off of hypnosis since I was 13, 14, to the end of my career. I always had hypnosis before I fought.
“It only works with, and only certain people get it. Not everybody gets it.

"I guess that’s what life is all about. Not everybody’s the same, but I got it, and it’s all about reaching your self conscious.
"You have a connection with your self-consciousness and your ferociousness.
“Everything’s about being connected and using that for your fighting. Everything’s love. Everything is connected to love.
"Even us that’s going to war. I got hooked back. And it’s war, and there’s love. Everything’s love.”
While Tyson has given up sex, Paul has revealed he won't be following suit.

He said on his podcast: "If I didn't have sex for like… if I restrain myself for like two weeks I start having wet dreams because my body's like, 'Get this out!'
"It's not weird, it just means that I'm normal."
