After gorging himself on lavish cuts of Japanese wagyu beef and tables full of burgers and pizza, Jake Paul has pumped the brakes on piling on the pounds for his fight against Mike Tyson. 

The YouTuber-turned-boxer will square off against 58-year-old legend Tyson on November 15 in a controversial clash that’s set to make each man tens-of-millions of pounds. 

The punch-up, which will be Netflix‘s first foray into streaming live boxing when it airs at 4am UK time on Saturday, will be former Disney star Paul’s debut fight as a heavyweight. 

Previously a cruiserweight, where the maximum weight allowed is 200lbs, the 27-year-old has beefed up to new levels, sparking accusations he used steroids to achieve his hulking new physique, while he insists it’s all down to protein, yogurt and fruit. 

Meanwhile, Tyson has given up his vegan diet but has backtracked on his own claim that he was eating raw meat to get in shape. 

Heavyweight fighters must weight a minimum of 200lbs, but there is no upper limit and Paul and Tyson are expected to weight in at 220lbs and 235lbs respectively.  

The pair were meant to meet on July 20 but Tyson – who was dubbed clinically obese in 2009 after ballooning to 27 stone – was forced to postpone having suffered an ulcer ‘flare-up’ while on a flight. 

‘Problem Child’ Jake had beefed up to 230lbs (16st 4lb) ahead of the bout until reformed vegan Iron Mike was forced to out. 

Instead Paul had to fight ex-UFC star-turned-bare-knuckle boxer Mike Perry, 32, who stepped in as a last-minute replacement, fighting at 200lb cruiserweight level. 

The change meant social media influencer Jake had to scramble to lose more than two stones in just a month, to get to the 14st 4lb weight limit.  

The YouTuber, who is brothers with Logan Paul, went on to win the fight after six rounds, with three knockdowns.

But his strength and conditioning coach Larry Wade admitted the drastic cut in weight had taken its toll on the young fighter. 

And it prompted a radical rethink from Paul’s training camp in how he prepares for his match against Tyson, once considered ‘the baddest man on the planet’.

‘He needed a break so we took a month off, got right back into it and now we’re getting ready for Mike,’ said coach Wade. 

‘We’re not as heavy as we were before which is a plus for us. I didn’t want us to go back up but you can guarantee he’s going to be ready fight night.’

Jake now aims to fight at about 220lb – more than a stone lighter than when he would have squared up to Tyson in July. Meanwhile Tyson is predicted to be around 235lbs when he steps into the ring. 

Ahead of his match, Jake revealed how he was able to bulk up so much to fuel his new-found hobby. 

His diet consists of mainly eating whole foods like eggs, potatoes, steak, chicken, yoghurt and fruit. It fuels his training sessions, which he does twice a day, five to six times a week. 

And in pictures on social media he has been seen tucking into burgers and pizzas. 

Some fans have been alarmed to see him dancing around tables full of junk food, with a rather large gut. 

But he’s confirmed he was wearing a prosthetic belly as a joke.  

Paul, who has an estimated net worth of $80million (£62million), instead regularly dines on Japanese wagyu beef – famed for being one of the most expensive cuts of meat in the world. 

‘This is what really keeps me going. I look forward to eating this every night,’ Paul told Men’s Health, adding he also enjoys tucking into smoked salmon and angus beef tenderloins. 

It’s a diet backed by British boxing veteran Quinton ‘Q’ Shillingford, who coaches English and Team GB fighters. 

‘I’m all for carnivore diet in boxing,’ the 57-year-old coach from Portsmouth, Hampshire, told MailOnline. ‘Natural food is always best.

‘My old coach used to say it’s all about portion sizes and if it doesn’t run around, swim around or grow from the ground, don’t eat it. Jake Paul’s ‘caveman diet’ is spot on, I think.’ 

The boxer, who has 142 competitive bouts to his name, losing just 22, claimed it would have been easy for Paul to yoyo his weight. 

‘Slashing 20lb is not that difficult if you’re full-time training and you’re getting the right fuel going into the body and you’re cutting out all your snacks,’ he added.

‘And it’s hard to put this weight on. If you get a personal trainer and nutritionists, it’s easy enough to do… And Jake Paul has the money to do this.’

Meanwhile for Iron Mike, preparation has been focused on getting him fight fit once again to take on the man 31 years his junior. 

Tyson, famed for his ruthless brutality in the ring, is one of the greatest heavyweights of all time, battering his way to 44 wins by knockout during his career. 

At 22, his body was a mass of brawn and muscle, making him one of the most powerful hitters the sport had ever seen, weighing in at around 218lbs at his peak.

Tyson retired from the sport in June 2005 – having been handed a 10-year jail sentence in 1992 for raping an 18-year-old beauty pageant contestant Desiree Washington.

In the years since, the boxing star ballooned in weight. 

By 2009, it was reported that weighed up to 27 stone and was labelled clinically obese, amid an ongoing battle with drug abuse, and was now some 170lbs heavier than his prime.

But Iron Mike took up veganism in 2010, ditching meat altogether, and revealed just what an impact his dietary switch had: ‘I was so congested from all the drugs and bad cocaine, I could hardly breathe.

‘I had high blood pressure, was almost dying and had arthritis. Turning vegan helped me eliminate all those problems in my life.’

Over the next 11 years Tyson began to shed the weight he had gained thanks to a combination of his new diet and more time spent exercising and in the gym, and by 2020 he was in an incredible state for a 53-year-old.

That year, Tyson stepped back into the ring in an exhibition bout with Roy Jones Jnr, which ended in a draw by WBC scoring, but Iron Mike was backed to his regular ripped physique.

The then-54-year-old came in at his customary 220lbs, and it perhaps didn’t get the pay off it deserved, with controversy surrounding the result with many believing Tyson should have won after massively out-landing Jones, but a draw it was.

Ahead of the previously scheduled date in July, Tyson revealed he was eating raw meat in preparation for the clash – in a huge change from his vegan diet. 

‘Raw meat. I have to eat it now because my opponent is going to be raw meat,’ he said when asked why he looked so good on the Damon Elliott Show.

However, the former heavyweight champion of the world rowed back on that claim in a recent sit down with Netflix.

‘I would never eat no damn raw meat.’ He replied when asked if he was still devouring uncooked meat. ‘My wife eats raw meat, but I don’t eat raw meat. The Japanese stuff, sushi’ 

Tyson has recently shared new images of his new ripped physique, appearing noticeably more bulky than back in December 2023. 

But despite seemingly getting back into shape, boxing expert Quinton Shillingford said Tyson would be plagued by health issues his younger opponent wouldn’t have. 

‘Tyson is my age,’ he said. ‘Your bones and muscles don’t work the same… It will be difficult. 

‘He has brilliant muscle memory and he has been boxing all his life, so it’s not about that. It’s about his joints.’

Giving his take on the fight, Quinton added: ‘Jake Paul is delusional. I’ve had 142 bouts and I wouldn’t want to go in the ring with Mike Tyson. Tyson is a lot older but watching him train, he still looks quite vicious.

‘I can’t see Jake Paul winning – I don’t think he hits hard enough.’

Tyson and Paul are expected to walk to the ring at around 4am UK time on Saturday, which will be around 10pm local time on Friday in Dallas, Texas. The fight will be shown live on Netflix.
