Inside Tyson Fury’s camp where he has been BANNED from Diet Coke and fast food to get in shape of life for Wilder clash

, Allcock said: "Tyson has been sparring amazingly. Everything has been put into place done properly has benefited him.

"The big differences have been food, particularly strictness with what is in camp - silly little things like cans of Diet Coke have gone.

"We've also cut a lot of out of the way in terms of people visiting the house willy nilly. There has been loads of different things which has brought together everything together like it should be to prepare for such a big fight.

"It's been a hell of a lot more disciplined and it had to be a bit like this. The last fight was very much like Rocky III when he fought Mr T's character.

"It was too much in the limelight, too much of the fakeness and we just had to go back to basics and pull the rope on certain things."

Fury has split with trainer Ben Davison, but Allcock revealed that it wasn't his decision.

"Tyson wanted Ben [Davison] in the camp, it was Ben's decision not to come into camp," he explained.

"But now there's been a massive change in the trainers as well which has benefited him [and Isaac Lowe] massively."

Allcock went on to elaborate on just how much Fury's eating habits have improved.

He said: "We definitely had to rope in the food. Tyson never really stuck to the diet plan we gave him last time, he was always nipping out and eating fast food outside the camp - and all that has changed now.

"Everything has worked for the best as Tyson knew if he went into this fight the way things were going, he probably wouldn't stand the chance he has now.

"I'd say Tyson respects Wilder more in this fight, but Tyson knows he can beat him. The way Tyson has changed things, he is a better fighter because of it, which brings more chance of winning the fight."

Fury's US promoter Bob Arum also believes that he has improved his lifestyle - and claims that he could continue fighting for another "six or seven years".

He said: "Tyson fights for fame and fortune. He will make an awful lot of money from this fight and will provide the opportunity for his family, his children and his grandchildren, which is why you keep fighting.

"He's barely over 30 and how long left depends on him and his lifestyle. If he continues with his current lifestyle, he could go on for six or seven years.

"If he reverts to some of his old habits, it'll be a much shorter period.

"No scenario because Joshua, who has the titles he won back from Andy Ruiz, has two mandatories which he must do against Pulev and Uysk.

"As far as I am concerned, the earliest a unification fight can take place is 2021."
