Tony Bellew will bid to become the unified cruiserweight world Champion when he faces the Ukrainian Oleksandr Usyk on Saturday night.
Bellew has revealed the sacrifices he has made as he returns to the 200Ib division after a stint at heavyweight.
"It’s been so long this camp. Its been so hard. I have not had a piece of bread for three months," he told Sky Sports.
"I haven’t had a fizzy drink for three months. I want a bar of chocolate really, really bad and I can’t have one until Sunday."
