CRAIG Booby is looking for love now that he has won The Biggest Loser: Challenge Australia.

The Ararat sales manager dropped a staggering 43.51 per cent of his body weight to snatch victory in the Channel 10 weight-loss show.

The future of the program, however, is under a cloud due to poor ratings.

The 34-year-old was this year's heaviest male contestant at 183.4 kilograms when he weighed in at the start of The Biggest Loser and left the competition 79.8 kilograms lighter.

Booby now has his sights set on finding a partner and starting a family. His last relationship ended five years ago and he blames the break-up on his then ballooning weight.

"I've certainly got a lot more confidence than I've ever had," Booby says. "Before I was always self-conscious and worried about how people saw me. Now I'm going out there proud of who I am and what I've achieved.

"I think that will help me meet someone and start a family, for sure."

Biggest Loser trainer Steve 'Commando' Willis has praised Booby's dedication to toughing out the show's 11 weeks of gruelling challenges.

"Craig was the definition of hard work," Willis says. "From the moment he entered the Biggest Loser house he gave it his all.

"I constantly encouraged him to strive for more and dig deeper to be the best possible version of himself."

Booby takes home a $75,000 cash prize for his win.

The Ararat community - which was this year a feature of the series - lost a total of 40,000 kilograms,well ahead of the town's 26,000 kilogram target.

Booby finished ahead of Toni Stockwell who shed 38.41 per cent of her starting weight — from 124.2 kilograms to 76.5 kilograms.

Sharon Bassett lost 36.61 per cent — down from 109.8 kilograms to 69.6 kilograms.

Katrina Pianta rounded out the final four — dropping 33.41 per cent — from 131.1 kilograms to 87.3 kilograms.

"I knew from the start that I had a goal and I set aside time in my life to achieve it," Booby said.

"Nothing was going to get in my way. I've come too far and I realise how much healthier and happier that I am. Knowing the hard work I've put in there's no way I'll let it slip away (put weight back on)."

Channel 10 is yet to commit to another series of The Biggest Loser which has struggled against My Kitchen Rules and The Block: Fans v Faves in recent months.

"An announcement regarding the next season of The Biggest Loser will be made later in the year," a Ten spokesperson said.

But Ten CEO Hamish McLennan appeared to foreshadow the show's demise in an interview with The Australian last week.

He revealed that the current season of Loser actually finished shooting nine months ago.

"Some of the franchises that rode off the back of Sochi like The Biggest Loser are getting towards the end of their life cycle, and much of the content was in the can nine months ago, so we have to run it out," he said.
