"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 on MAFS, but that doesn't mean I'm any 'better' now, just because I'm slimmer."
However Elizabeth maintains that her drastic weight loss is the result of illness not dieting.
Speaking previously to an Australian magazine, the MAFS star said she had lost weight because of an auto-immune condition similar to lupus.
This means Lizzie needs to follow a strict eating plan and adheres to a high-carbohydrate diet.
She also says no to coffee, tea and alcohol.
