Nine months later, Mr Tirekidis is 65kg lighter – with the help of a hypnotist – and now wants to be a personal trainer.
“Just the basic things are easier to do like getting in the car, walking around, going up the stairs,” the 44-year-old said.
Instead of devouring 10 hash browns and two coffees at breakfast, the Dulwich Hill resident now eats yoghurt with berries and hits the gym up to six days a week.
Gone are the four Hungry Jack’s meals for dinner, replaced with chicken, fish and salad.

Mr Tirekidis credits much of his success to hypnotist Mark Stephens who encouraged him to associate his favorite foods with bad smells and foul images.
“We were dealing with someone with a major food addiction,” Mr Stephens said. “He was like the walking dead.”
