She has tried Ozempic in the past to lose weight but suffered a terrifying overdose. 

Now Roxy Jacenko swears by a new supplement which she has called a 'natural Ozempic'.

The PR queen, 44, celebrated wellness brand Eimele new weight loss supplement at a lunch at Little Felix restaurant in Sydney on Tuesday. 

She gave an insight into her daily ritual and 18kg weight loss over the intimate lunch with friends.

According to the website, Eimele provides 'plant-powered solutions' for a variety of concerns, including weight management. 

The brand's Calibrate Reds Max is said to help 'limit sugar and carb absorption' while simultaneously 'reducing fat storage'. 

The powder sachets are designed to be taken dissolved in water at the start or during the biggest meal of the day. 

During the soiree, Roxy showed off her slender figure in a $899 mini dress from Leo Lin. 

The stunning strapless frock featured large embroidered flowers on the front and revealed a hint of her cleavage and slim pins.

The savvy businesswoman had her signature blonde locks coiffed in waves, along with a bronze makeup look that highlighted her youthful visage. 

Of course, Roxy was dripping in diamonds, including a sparkling tennis necklace and large diamond pendant.

Roxy previously 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. 

'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.

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

'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 recently spoke about the terrifying moment she overdosed on Ozempic in an effort to lose weight.

She revealed she'd taken four times the recommended dosage before she suffered from 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.

'I bought it, I tried it. I took four times the amount in the first go.'

Roxy continued by saying she's 'so sick of people' who deny using Ozempic, adding: 'I call a spade a spade on my platform and I don't care.'

She also previously said she thought she was going to 'die' after taking one milligram of the diabetic treatment, which was four times the amount prescribed to her by a doctor.

'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.

'For the first 12 hours I was OK. I vomited four times that morning, once in a hire car, and I went to work.'

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