Big Brother’s Kieran Davidson reveals how he lost 15 KILOS in the house

When he entered the Big Brother house, Kieran Davidson tipped the scales at 129kg.

But the Adelaide videographer, 21, managed to lose an impressive 15kg thanks to his time on the Channel Seven reality show.

Speaking to TV Week, Kieran credited his huge weight loss to living on food ‘rations’ in the house and not eating fast food.

‘I’ve always been a bigger guy, because I love fast food and eating out,’ he said.

‘But I knew I needed to lose some weight. Being on food rations and not having any of the chocolate or crap I eat outside was a sure-fire way to do it.’ 

Kieran also revealed that fellow housemate Soobong Hwang taught him some simple exercises to help shed the kilos.

The exercises, coupled with his restricted diet, saw Kieran lose 12kg in the house and he has lost a further three kilos since returning home. 

Kieran, who was bullied at school for his weight, said that going on Big Brother had encouraged him to lead a more active lifestyle by ‘going for walks’ and ‘hitting the gym’.

‘Now I’m hitting the gym, going for walks with my dad and even running. It’s a bonus that Big Brother’s improved my life,’ he said.

This comes after Kieran was spotted playing a game of tennis with his father, Shane, in Adelaide, on Saturday.  

The YouTube star is certainly used to playing games by now, after proudly using manipulation tactics on Big Brother. 

Back in May, Kieran claimed he would be the ‘type of housemate that won’t be afraid to say it how it is’.

‘[I will] make bold strategic moves and lie and cheat to get to the end of the game,’ he told the Daily Telegraph.

‘I look forward to playing the game in the house, it’s the main reason why I applied and it’s the main reason why I feel I have the best chance at winning.’

Big Brother continues Monday from 7.30pm on Channel Seven
