Sporting a sleeveless khaki wrap dress in the teaser image posted to Instagram on Friday, Julie exposed her muscled biceps and toned forearms.

It wasn’t long before the news was inundated with comments from thrilled MasterChef fans.

‘Can’t wait! Absolute legend,’ one viewer commented.

‘LET’S GO JULIE,’ said another.

‘From feeding the needy in Gosford to where it all started. It shows you the amazing heart Julie Goodwin has,’ a third chimed in.

Julie’s exciting announcement comes just days after she issued a statement defending her weight loss after fans raised concerns about her health.

Julie shared an update on Instagram after a new photo, in which she looked very slim, was posted to her account.

Her dramatic transformation led to comments from worried followers.

‘Thanks to all who have expressed concern about my health,’ she began.

‘I am well and I am within the healthy weight range. My doctor concurs,’ she continued.

‘For those who have asked me for advice or tips, I am not qualified to provide this. It’s advice that should be sought from your trusted health professionals, not from me. I’m a TV cook,’ Julie continued.

‘For those who want to comment on the shape and condition of my body please, do it on your own page because I’m tired of reading it. For that reason I’ll be turning off comments on this post.

‘For all of us can we please find something more interesting to talk about. Can we please model kindness to our kids and grandkids and can we please leave this obsession with people’s looks back in the 1980s. Peace and love.’

The celebrity cookbook author shot to national fame after winning the inaugural season of Network Ten’s MasterChef Australia in 2009.
