Experts say the latest Netflix teen drama could be triggering, damaging and distressing for people struggling with an eating disorder.
To The Bone stars Lily Collins, who lost weight to play the part of a girl struggling with anorexia.
It's described as a dark comedy, but there are concerns about dramatising dangerous thinness.
Anorexia survivor Millie Thomas fears it will have a triggering effect.
"I know for me, when I was sick, if I had watched that, and I didn't feel or see myself as being as thin as the girl who was on there, then say I'd say 'I need to get thinner, I'm not being a good enough anorexic'."
Two years ago, Ms Thomas was given two weeks to live. Her parents were told it was the end and to prepare for palliative care.
In a last ditch attempt, she sought help in Australia. Now, she's fully recovered and mentoring others at EndED on the Sunshine Coast.
Ms Thomas says it's important to raise awareness, but fears To The Bone could compound the myths.
"I don't think that what is termed a dark comedy on Netflix is probably the right way to go about it," she says.
"Eating disorders are not a choice, they're not just about control, they're actually biological illnesses."
The number of people seeking specialist help for eating disorders in New Zealand has increased in recent years.
Last year, 1289 people were treated, almost half were under the age of 19.
British actress Lily Collins, who has also starred in The Blind Side and Mirror Mirror, is an eating disorder survivor herself.
The Eating Disorders Association praises Collins for being so open, but also raises concerns.
"We are concerned that she went to the extent of losing weight to play a part," says EDANZ president Nicki Wilson.
"The content of this movie and the way in which eating disorders are portrayed could be really distressing, could be triggering, could be quite damaging."
Nicki Wilson also points out that eating disorders affect people of all ages, sizes, ethnicities, socio-economic groups and genders.
She says the knowledge and treatment of eating disorders has dramatically improved in recent years.
"The key message is that eating disorders are treatable, and full recovery is possible."
Ms Thomas is testimony to that.
"My Mum refused to give up," she says.
"The fact that someone still had hope in me and hadn't given up was a huge reason why I decided to give it one last shot and that's what saved my life.
"If you want it bad enough, you can, you can fully recover."
