Model Simone Holtznagel flaunts her alarming weight loss in post-workout bikini selfie – after her PT boyfriend insisted her weight loss ‘wasn’t done starving’

She recently lost an impressive 10kg after hitting the gym with her personal trainer boyfriend Jono Castano.

And Simone Holtznagel showed off her dramatic weight loss on Monday when she posed for a post-workout mirror selfie before hitting the sauna.

The 29-year-old Australia’s Next Top Model star showed off her tiny waist as she stripped down to a white string bikini in a photo shared to Instagram.

“Sweat out the weekend,” she wrote in the caption.

It comes after her partner Jono insisted her weight loss was the result of healthy eating and exercise and “not starvation”.

In the picture, Simone covered her face as she flaunted her slim figure in the women’s changing room at Sydney’s Acero gym.

It comes after the blonde bombshell showed off her slim figure in a black lingerie set earlier this month.

“Wearing Nala underwear makes today’s Digi-Tag a little less intimidating,” she wrote.

Her slim midsection and toned legs were on display, as were her noticeably slimmer arms and defined triceps.

Simone debuted her body transformation in August after losing weight over the course of 10 months with the help of her PT boyfriend Jono.

At the time, Jono dismissed any suggestion that her weight loss was too drastic, telling Chron Australia: “The way she got results wasn’t by starving herself; it was implemented through a structured program.’

Simone ate four meals a day and her diet was “very balanced, with all of her macronutrients included in each meal,” he explained.

The socialite resisted backlash after revealing her body transformation, but said at the time she had ignored her critics.

“People have commented that ‘triggers’ and ‘before and after’ doesn’t belong in 2022…” she told the Daily Telegraph.

“I figured what we wouldn’t do in 2022 was comment on other people’s bodies,” she added.

Jono and Simone met a few years ago when she was one of the trainer’s most prominent clients.

They initially kept their romance under wraps before going public in May last year when they were spotted kissing at Mimi’s restaurant in Coogee.

Jono was previously married to Acero gym owner Amy Castano.
