What We Can Learn from Netflix’s Anorexia Movie To the Bone

Extreme relationship with food, wearing layers of clothes, constantly measuring her arm with two fingers to see how far away they are from touching the tip of each other, Ellen’s behavior in the movie To the Bone may not be strange to those who have had or know someone who has suffered from anorexia. 

Despite criticism it has received, the movie did manage to cast some light on the underlying issues of the eating disorder, and offers patients, their friends and family hope that this can be cured. Nonetheless it was still heartbreaking to watch, especially the beginning of the movie.

Eating disorders, including anorexia nervosa, bulimia nervosa and binge eating disorder, have affected on average 8.4% women and 2.2% men in the world, according to a 2019 study[1]. Up to 4% women have had anorexia in their life[2].

What is Anorexia Nervosa?

Anorexia nervosa is characterized by weight loss or lack of appropriate weight gain in growing children, difficulties maintaining an appropriate body weight for height, age and stature, and in many individuals, distorted body image[3].

DSM 5, the 2013 version of the Diagnostic and Statistical Manual of Mental Disorders, states that the diagnosis of anorexia nervosa must include all of the following criteria[4]:

  • Restriction of energy intake relative to requirements, leading to a significantly low body weight in the context of age, sex, developmental trajectory, and physical health. Significant low weight is defined as a weight that is less than minimally normal or, for children and adolescents, less than that minimally expected.
  • Intense fear of gaining weight or of becoming fat, or persistent behavior that interferes with weight gain, even though at a significantly low weight.
  • Disturbance in the way in which one’s body weight or shape is experienced, undue influence of body weight or shape on self-evaluation, or persistent lack of recognition of the seriousness of the current low body weight.

DSM 5 also uses BMI to indicate the level of severity – mild (BMI>17 kg/m2), moderate (BMI=16~16.99 kg/m2), severe (BMI=15~15.99 kg/m2) and extreme (BMI<15 kg/m2).

In the movie, Ellen is a typical anorexic. She has a very skinny body. She wears layers of clothes and develops lanugo because her body can’t generate enough heat. She is obsessed with sit-ups and running up and down the stairs, especially after eating. As what they call “calorie Asperger’s”, she memorizes the calories of almost everything on the plate. Because of her difficulty in maintaining body weight, she was in and out of recovery programs.

Two subtypes of anorexia nervosa are identified – restrictive anorexia and binge-eating/purging anorexia, based on whether the patient has binge eating and/or purging behaviors[5].

Ellen is a restrictive type. She is never into purging. On the other hand, two of the house members are the binge-eating/purging type. One is her roommate, who would hide a bag of vomit under the bed. The other is a pregnant woman, who miscarried her baby due to resuming purging after the 12-week mark, thinking that it would be safe to do so.

You may wonder, what is the difference between the binge-eating/purging subtype of anorexia and bulimia? It lies in patients’ BMI. Patients with anorexia subtype are typically underweight (BMI < 18.5 kg/m2), while those with bulimia tend to be normal weight or overweight (BMI >= 18.5 kg/m2)[6].

Causes of Anorexia Nervosa 

Many factors are thought to contribute to the onset of anorexia nervosa. This includes biology, psychology, environment and culture.

In an article called “Rethinking Anorexia” published recently by AAAS (American Association for the Advancement of Science), researchers found that the disorder is rooted in the genes. Psychologist Cynthia Bulik and other researchers identified eight statistically significant genomic regions related to anorexia, and overlapping associations with DNA controlling BMI, lipids and other metabolic traits[7].

Anorexia nervosa is said to be typically characterized by a fear of gaining weight, but same article revealed another interesting point from the psychologist. As what she mentioned in the article, to a lot of her patients, it was never about being thin.[8] 

On the other hand, To the Bone touches on other causes of the disorder.

Ellen’s family environment is complicated to begin with. Her parents have divorced. Her mom came out as a lesbian and lives with her partner in a ranch. Her father later married another woman. Ellen used to live with her mom and the partner, but then the couple couldn’t stand her self-destructiveness anymore, so Ellen went to live with her stepmom and her dad, who never showed up in the movie.

Towards the end, Ellen’s mom cradling her and feeding her from a bottle revealed the fact that her mom had postpartum depression, which possibly caused absence of bonding after Ellen was born.

All of these environmental and parental issues may have promoted and sustained Ellen’s eating disorder. To her, not eating and the obsession of sit-ups may be the only way to relieve her culpability, or “fault and blame” according to Dr. Beckham, shut down from reality where love is lacking.

Whether it’s Dr. Beckham’s condemnation of fault and blame, Ellen’s mom’s attempt to resolve bonding issues, or Luke’s encouragement, they all helped in supporting Ellen’s recovery along the way.
