SAS Australia star Isabelle Cornish has revealed how her on-and-off battle with disordered eating led to an exciting new career path.
The 27-year-old, who is the younger sister of Hollywood actress Abbie Cornish, admitted that she was hyper focused on her "external image" after being thrust into the spotlight as a young woman.
"I had periods where I suffered from an eating disorder on and off.
"I didn't know how to deal with my emotions and all the stress and everything so an eating disorder was kind of my coping mechanism," she told the Daily Telegraph.
Isabelle's disordered eating and body image struggles came to a head in 2014 after filming for Puberty Blues wrapped and she moved to the United States.
"When I was super young, like 18, I did have bulimia for a year and then it went away and I was fine for a couple of years and then it came back in a different form," she said.
The Nine Perfect Strangers star revealed she became "obsessive compulsive" around food, and even avoided entire food groups altogether.
Eventually Isabelle formed a healthier relationship with eating and now says studying food psychology and yoga has become her passion.
"Studying was the catalyst of my healing journey.
"I recovered from my eating disorder and studied all different sorts of things so I like to say my poison became my passion," she said.
Not only has Isabelle turned what was once a cause of heartache for her into a passion, she's now recently completed her Certificate Four in Personal Training.
Isabelle has previously opened up on her website about how the psychology behind food offered her a "deep insight into the healing journey".
"I have gained an expansive outlook on eating disorders and unwanted eating habits," she said.
"Growing and developing during puberty while being in front of the camera sparked my fair share of unwanted feelings and symptoms such as poor body image and unbalanced eating habits."
The SAS Australia star described hunger as not only physical, but "emotional and spiritual," encouraging her followers to start asking questions about what their eating habits may mean.
