She's just transitioned from single life to being a wife – but that's not the only transformation Married at First Sight's Cathy Evans has undergone.
"After gaining weight, thanks to partying at uni, I got into body building four years ago," Cathy, 27, tells OK! exclusively.
"Friends of mine were into it and as I started finding out more about it I got inspired. I wanted to get a body I could be proud of."
After some serious hard work in the gym, Cathy was ready to strut her ripped stuff on stage!
"I got down to a very ripped 49kg and placed sixth in a national body building comp," she explains.
"It was incredible to hear people cheering my name."
But after achieving that success, a move from New Zealand to Australia and a bad break-up meant the logistics investigator's weight crept back up to 78kg.
"I was that weight for around nine months,' she says. 'I'm only 152cm tall, so it was a lot for me."
With an ambition to work as a personal trainer, Cathy decided to train herself by hitting the gym once more and, initially, took inspiration from the low-carb, high-fat keto diet.
Eventually, Cathy's weight settled back at 'around' 62kg.
"Nowadays, I don't exclude any food groups and I just make sure I move around a lot," says Cathy.
"I walk to work and I take the stairs rather than a lift where possible. I also eat lots of vegetables with every meal."
That regimen meant Cathy looked absolutely stunning at her wedding to groom Josh Pihlak!
"I'm feeling great," she says.
