Tyson Fury has revealed he drank 18 pints of lager a night at the height of his alcohilism.
The former heavyweight world champion sank into a deep depression following his victory over Wladimir Klitschko in 2015.
He turned to drink and drugs as he struggled to cope with being catapulted to the top of the sport and ballooned to 400lb.
But Fury has turned his life around and shed 150lb as he prepares to face Deontay Wilder in December.
And he told the Joe Rogan Experience : “I was eating a lot and drinking a lot and I just stopped that stuff.
“My weight was put on through drinking excessive lager. There are 500 calories in a pint of lager and I would go out and drink 18 of them followed by whisky and vodka, then I’d stop off on the way home and eat pizzas and kebabs.
“I just trained on a daily basis for a long time and ate sensibly and clean.
“Before I was doing a lot of long running and long boxing work, like 12-15 rounds on the pads. When I was losing the weight I was doing shorter, explosive stuff, doing more interval training.
“My diet was the most important thing, you can train like a Trojan warrior but not eat right and take three steps forward and two and a half back.”
Fury has fought twice since deciding to come out of retirement earlier this year.
A facile victory over Sefer Seferi was followed by a points win over Francersco Pianeta before Fury agreed a deal with WBC world champion Wilder.
The 30-year-old has relocated to Big Bear in California to complete his training camp.
And he said: “When not training I am thinking about training, when I’m not thinking about training I’m sleeping, and when I’m not sleeping I’m eating, when I’m not eating, I’m resting, watching TV,” he said.
“Training at altitude has been very hard. The air is thin and it’s hard to breathe. I came over here and I was already very fit, could fight 12 rounds on the pads, no problem. Here, I am tired after three or four rounds.
“I don’t leave Big Bear. I went down a mountain to Ontario last week, just to check everything was going right. I was feeling very tired in the gym – I was speaking to Lennox Lewis on the phone and he told me he got out of there after a week.
“He said he hated it and it was too hard. I went to sea level, and I was very fit.”
