Boxing: Kiwi heavyweight Joseph Parker has social media retching as he eats raw fish from bucket

Kiwi boxer Joseph Parker is no stranger to social media, but usually he's lip-synching one of his favourite tunes or flexing his muscles in the gym.

His latest video has the internet wishing it could unsee what it just saw.

Responding to a question about his favourite Kiwi food, Parker, 32, confesses his love of raw fish and then posts graphic vision of him ripping one apart with his teeth straight from a bucket. 

Followers don't know what to make of the display.

"What is he trying to prove?" wondered one.

"He about to get salmonella," suggested another.

"Check his basement freezer for human remains," warned another.

"Rich people call it sushi," insisted another.

"I do it on a daily basis," Parker told fellow Samoan heavyweight Jai Opetaia. "Protein, if you want proper protein... fresh."

The former WBO world champion has reinvented himself, since joining Tyson Fury's camp and training under Andy Lee. One of the biggest changes has been his diet.

"Even though Sunday is a day off, we load up for Monday, because Monday is a heavy day," said dietitian George Lockhart. "We go to this sushi place and he'll eat 40 pieces of sushi.

"There's pictures of them bringing out these massive boats. Every time we go to that place, people are, like, 'This is for four people', and Joe downs it like nothing."

Parker is currently awaiting his next fight, after thrusting himself back in the top echelon of heavyweights with emphatic back-to-back wins over American Deontay Wilder and Chinese Zhilei Zhang, which earned him the WBO interim title.
