Podcaster reveals the brutal reality of Bec Zacharia's body-altering 'Barbie waist' surgery - after the MAFS star changed her mind again and booked a date for the controversial procedure

A podcaster has revealed the brutal reality behind the controversial 'rib contouring' surgery Bec Zacharia is undergoing to achieve a 'Barbie waist'.

The Married At First Sight star, 35, has been in the headlines recently after she initially backed out of doing the Bali procedure, but has since decided to go through with it.

Now, the podcaster documenting her journey, Josh Fox, has revealed on 2DayFM Breakfast with Nath & Emma that the surgery will 'fracture' her ribs.

'It's almost like a needle either side and that shaves off and fractures your bottom ribs, the floating ribs, and then they can turn them in slightly,' he said on Friday.

'So they can actually bend your bones?' asked host Emma Chow. 

'Yeah. Afterwards, these girls have to wear a corset for 12 weeks, and how tight they wear that corset determines how small their waist is going to be,' Josh said.

Co-host Nath Roye went on to ask who was paying for Bec, and the other influencers she was travelling with, to have the procedure done. 

'So this group of girls, they're kind of there on contra. "We'll give you that and cover the expenses if you're posting about it and promoting it,"' Josh explained.

'So they haven't paid for anything for their rib contouring,' Nath said.

'That's why I went. Because initially, I said no to this, like documenting it,' Josh said. 

'But then I thought, if I don't go and try and skew the narrative and ask questions, all we're going to get is 10, 20 influencers going, "Look how great this new thing is."'

Josh went on to say he believes Bec and fellow MAFS star Awhina Rutene are getting the surgery done because they are 'insecure'. 

'It feels bad saying it, but they're all just very insecure in my eyes. Like, Awhina told me, she loves her body before and she'll love it afterwards,' he said.

'She just said she'd like this. But then like, Bec from MAFS, she is an insecure woman. We know that. That's why I was happy she [initially] backed out.'
