Binge Eating Disorder & Obesity Statistics

Three Obese Ladies

To better understand the complicated relationship between obesity and binge eating disorder and other eating disorders, a group of researchers from Sydney, Australia reviewed the topic and published recommendations in the journal Nutrients.

In the article, “Obesity with Comorbid Eating Disorders: Associated Health Risks and Treatment Approaches” they conclude, “to improve the healthcare provided to these individuals, there is a need for greater exchange of experiences and specialized knowledge between healthcare professionals working in the obesity field with those working in the field of eating disorders, and vice-versa.” [1]

The researchers cited one study in the United States which found that 87% of individuals with binge eating disorder, and 33% of individuals with bulimia nervosa, had also had obesity at some point in their lives.

They also note that the likelihood of developing an eating disorder increases when an individual experiences size discrimination. The authors write, “discrimination against individuals with higher body mass index (BMI) can be particularly problematic because it can induce strong dissatisfaction with one’s body weight and/or shape.”

Additionally, when an individual experiences both obesity and an eating disorder, there is an increased chance of having a co-occurring mood or anxiety disorder, as evidenced by these findings:

  • A study with 152 treatment-seeking individuals with obesity found that those with binge eating disorder had higher BMIs, more severe levels of depression and obsessive-compulsive symptoms, and stronger feelings of inadequacy and inferiority than those without binge eating disorder
  • Bariatric surgery candidates with comorbid binge eating disorder had significantly more mood and anxiety disorders than bariatric surgery candidates without binge eating disorder (27% versus 5% for mood disorders, and 27% versus 8% for anxiety disorders, respectively)
  • 40% of bariatric surgery candidates with comorbid binge eating disorder had a mood or anxiety disorder, with some participants having both a mood and an anxiety disorder

Group of ladies overcoming obesity and binge eating disorderUnfortunately, those who treat eating disorders, and those who help patients wanting to lose weight are not always working from the same set of assumptions. An individual with obesity may seek out a physician in hopes of dieting recommendations or bariatric surgery, yet find this professional has little to no knowledge of eating disorder behaviors.

At the same time, eating disorder professionals are hesitant to provide any weight loss recommendations, which may leave the individual feeling hopeless. The authors find this impasse unacceptable. They conclude:

“While these healthcare professionals may sometimes disagree on the potential benefits and harms of recommending weight loss diets to their clients, healthcare professionals working in either of these fields of obesity or eating disorders can acknowledge the common goal of promoting healthy eating behaviors, healthy relationships of their clients with their bodies, and positive personal health goals of weight loss.

“We contend that it is vital to develop and test innovative medical, psychological, and nutritional treatment options that simultaneously address obesity as well as comorbid eating disorders. Such integrated treatments can potentially induce greater improvements in health—and in more people—than treatments targeting only one or the other condition.”
