New South Wales mum Sarah Hill certainly got the internet talking when she posted her 40kg weight-loss before and after pictures.

Sharing on the Facebook group ‘Kmart Mums Australia Facebook’, she explained how she went from 130kg down to a Kmart size 12.

The post quickly went viral, attracting more than 7500 likes and hundreds of comments of support for the young mum’s “incredible transformation”.

In the post, Ms Hill attributes fitting into Kmart clothing as being part of her inspiration to lose weight, dubbing it ‘the Kmart Diet’.

Speaking to, the mum-of-one said she weighed 130kg at her heaviest, which restricted her to buying clothes only in sizes 24-26.

“At that size, my options were so limited, it was really hard to pick up an affordable outfit at Kmart or Target,” Sarah said.

“I would walk into Kmart, see all the gorgeous clothes I desperately wanted to try on and just keep walking straight to the plus-sized section.”

According to Sarah, the main motivation for her weight loss was to be able to fit back into the Kmart clothes she’d admired for so long — dubbing her new healthy lifestyle the “Kmart diet”.

“I paid attention to what I was putting in my mouth and was being as active as I could,” she said.

After dropping an enormous 42kg, Sarah recently walked into Kmart to try on her first outfit since her dramatic weight loss.

“I would usually wear jeans all summer, I never wore shorts or revealing outfits,” she said.

“So when I tried on that midriff top and skirt, and realised it was a size 12, I couldn’t believe it.

“I wanted to be able to walk into a store that wasn’t a plus-sized shop, see something cute, get it in my size and feel confident in it.”

Congratulations, Sarah!  You look amazing x
