Elizabeth has shed a whopping 10kg since first appearing on the show.
"I've thought that when I weighed 49kg and when I've weighed 90kg. I want women to realise that we're all so much more than a number on a scale," she revealed.
"So, yes, I've lost some weight since I was a 'huge' size 10 when I was onMAFS, but that doesn't mean I'm any 'better' now, just because I'm slimmer."
She has lost a whopping 10kg since first appearing on the show.
