Big Brother's Mitchell Giles reveals the schoolyard trauma that inspired his fitness transformation

He is the hunky FIFO worker who entered this year’s season of Big Brother as a late intruder. 

And on Wednesday, Mitchell Giles, 26, revealed the inspiring story behind his incredible fitness transformation.

‘I used to be a real chubby kid back in school and then got bullied heaps so I just sort of had enough of it,’ he told Daily Mail Australia.

Mitch said that he got ‘so sick’ of what he looked like that he decided to make changes by joining a gym and watching what he was eating.

‘I would go to the gym all the time and then just got hooked, he said.

The father-of-one went on to say that after learning he would be appearing on this year’s season of the Channel Seven reality series he went on an extreme diet. 

Transformation: Speaking to Daily Mail Australia on Wednesday, Mitch said his physique is the result of eight years at the gym after years of getting bullied throughout his schooling

‘It was crazy, I was in calorie deficit,’ he said. 

‘I ended up losing 10 kilos in six weeks, but just knowing that I was going to be on TV, it was enough motivation to trim right down.’

Mitch, who was eliminated during Wednesday night’s episode went on to say that he felt like he had a target on his back from the second he entered the compound.

‘Everyone knows as soon as you’re a little bit athletic you got a target on you,’ he said.

‘Pretty much from day one as soon as I popped my head out at the dinner they were like, “wow, you are a big man”, he said.

Big Brother continues Monday at 7.30pm on Channel Seven 

Evicted: Mitch was sent home after he received a whopping eight votes. Pictured with fellow housemates Brenton Balicki and Christina Podolyan, who were also up for nomination
