Roxy Jacenko flaunts her trim figure in white bikini as she poses with son Hunter at crystal clear beach during luxury getaway in Dubai

Roxy Jacenko set hearts racing on Saturday as she stripped down to a white bikini while enjoying a luxury holiday in Dubai with her 10-year-old son Hunter. 

The PR maven, 45, flaunted her toned abs in the crisp two-piece as she waded through the shallows of a crystal clear beach with her youngest child.

The mother-son duo could be seen posing with their arms around each other in a photo the entrepreneur uploaded to her Instagram Stories.

Hiding her eyes behind a pair of dark glasses, Roxy was all smiles as she showed off her trim pins, seemingly proud of the results of her recent 15kg weight loss.  

Roxy shares son Hunter and daughter Pixie, 13, with her husband Oliver Curtis. 

It comes after the PR queen revealed the extreme measures she goes to in order to maintain her goal weight of just 50.9kg.

She told Daily Mail Australia she is doing daily contrast therapy, which involves taking baths in warm and cold water from Monday to Friday.

This method is believed to help to improve blood circulation throughout your body.

She also does 40 minutes in an infra-red sauna each day before completing a 45-minute workout on the treadmill at speed 6 and rolling hills, as well as low-weight exercises.

Roxy also revealed she eats just one meal a day at dinner which is focused on protein only.

‘I don’t do breakfast or lunch, instead I do dinner at 7pm each day which is focused on protein only and salad,’ she explained.

‘Last night I had grilled calamari, rocket, pear and Parmesan salad. If I’m desperate for something sweet, I have dark chocolate-covered sultanas.’

Roxy also has an AG1 supplement, which includes multiple vitamins, minerals, probiotics and plant compounds, every morning.

She said she only drinks alcohol on the weekend if she has an occasion and even then limits herself to two drinks.

Roxy also recently spoke about the terrifying moment she overdosed on Ozempic in an attempt to rapidly lose weight.

She took four times the recommended dosage, resulting in severe vomiting and non-stop shaking.

‘I put so much weight on. I would have to undo my jeans when I sat in the car so I got sucked in by it,’ she explained on The Lazy CEO Podcast with Jane Lu.

She had consulted her doctor about it, and got a prescription, but ignored the guidelines when it came to safe dosage.

‘I thought I was actually going to die. I have had cancer, radiation therapy, all of that. It doesn’t even compare to how bad I felt when I took this drug,’ she told The Saturday Telegraph.

Roxy suffered from severe vomiting and non-stop ‘epilepsy type’ shaking which landed her in a drug overdose clinic for three days.

‘I called an ambulance. An ambulance was going to be an hour away but I thought I was going to die. I went to St Vincent’s,’ she said.

Roxy has since put out a warning to all who are tempted to use Hollywood’s latest quick-fix weight loss drug.
