Australian Survivor: Mark Wales unveils body transformation after shedding 17kg on the show 

Australian Survivor: Blood V Water winner Mark Wales has revealed he lost a staggering 17kg while taking part in the Channel 10 series.

The former SAS commander, 42, who took home the $500,000 cash prize on Monday night, said the game took a ‘huge toll’ on his body and that all the finalists felt themselves ‘deteriorating’ six weeks in.

In addition to revealing his weight loss, Mark also told news.com.au he had to live off a diet of mainly rice and lentils during filming, which lasted for 47 brutal days.

It was a similar story for his wife Samantha Gash, whom he met on the 2017 season of Australian Survivor.

After being eliminated on day 40, she revealed she had lost 6kg, or more than 12 per cent if her body weight, during her time in the outback.

‘I’m not celebrating this weight loss. It is part and parcel of the game of Survivor,’ she wrote on Instagram alongside a photo of her incredibly lean frame.

‘One that I willingly chose to do. The toll – physically (& mentally) is clearly evident with this,’ she added.

‘Playing Survivor is hard, I’m meant to be conditioned for this type of work but I could feel it breaking me down,’ he wrote.

‘The physical is endurable, it’s the dilemmas, the attachments, the losses, the fear, the grief and the emotional toll of that makes it so, so hard – AND, therefore – such a great story, an unreal game and the best show in the world.

‘Whatever happened out there, I always reminded myself that the night is always darkest before the dawn – there’s always hope.’

Mark went on to praise his ‘soulmate’ Sam, and said he’s ‘lucky to have played Survivor twice’.
