Elizabeth has been showing of her whopping 10kg weight loss since fans of Married At First Sight saw her on the reality show last year but some have also shown their concern.
“You look too skinny - not trying to be mean, just worried,” one fan wrote.
"This may come as a hate post but I honestly don't mean it this way. Your a beautiful person and I absolutely love you. However you look sick," another said.
"Totally agree," another person replied to the comment.
Famously fat-shamed by her MAFS husband Sam Ball who said she was “bigger than other girls he dated”, this isn’t the first time Lizzie has faced comments on her weight.
Lizzie chiming in on the comments herself, saying: 'I’m sick of this big girl nonsense! I like to eat healthy, I like to go on hikes I also like to pig out and stare at a wall.'
The star opened up in a past publication revealing she loves her body “at any size”.
The star added, “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."
