ALEX CANAVAN has put his stomach to the test by taking on a challenge to eat his way through a burger stacked 15 patties high.
When the Ipswich law student ordered the colossal burger at Burleigh Heads burger restaurant Ze Pickle, waiters and kitchen staff couldn't help but scoff.
The lean 23-year-old weighs in at a modest 75kg - not the typical physique for someone able to put away so much food.
But Mr Canavan said he didn't doubt himself for a second.
"Via social media, I learned that a customer at Ze Pickle had broke the restaurant's record by eating an 11-patty burger."
"I've been able to eat massive amounts of food my entire life, so I was keen to take on the challenge."
"I only needed to eat 12 patties to break the record but I told the manager I could do 15...the look on his face was priceless."
The challenge required Mr Canavan to eat - and keep down - the 3.1 kg wagyu beef burger in less than two hours.
If breaking the record wasn't incentive enough, a fellow customer at the restaurant learned of Mr Canavan's attempt and decided to raise the stakes.
"A man was having a few drinks at the venue and was so adamant I wouldn't complete the challenge that he bet me $1000 I couldn't do it," Mr Canavan said.
"He said he'd seen guys much bigger than me take on the burger challenge and fail time and time again.
As a uni student, Mr Canavan said he didn't have $1000 to lose, so failure wasn't an option.
"When they brought the towering burger out I was blown away by how meaty and greasy it looked," he said.
"After I ate the fourth patty, I was a bit worried because I started to feel full.
"But I slowed down and got into a rhythm of steady eating and had it finished with 30 minutes to spare."
Amazingly, he still had enough room to down a few celebratory beers afterwards using his winnings.
So how did Mr Canavan manage to eat so much food? And how does he remain so thin?
He attributes it to his active lifestyle which includes a lot of fat-burning, long-distance running.
"The morning of the challenge I did a 20km run, so I think that helped fuel my appetite," he said.
Working as a boarding master at Ipswich Grammar School and athletics coach at Ipswich Girls Grammar, Mr Canavan said news of his win had spread throughout the schools.
Photos of the challenge have also gone viral on social media sites Your Friends House and Shock Mansion.
