Taking a Bite Out of Eating Disorders: Facts and Myths

Eating disorders are serious mental illnesses that are more common than many people realize. Because eating disorders have such negative physical, psychological, and social effects, identifying and treating eating disorders is very important. In this article, we present symptoms of four different eating disorders: anorexia nervosa, bulimia nervosa, binge eating disorder, and other specified feeding and eating disorder. Next, we provide information to help “bust” common myths about eating disorders. We then offer examples of early warning signs of eating disorders to look out for in others and yourself. Finally, we discuss how to seek help if you are concerned about your eating behaviors. Specifically, we describe types of treatments for youth with eating disorders. With increased knowledge about eating disorder facts, you can help to take a “bite” out of the stigma of eating disorders.


INTRODUCTION
Eating disorders are serious mental illnesses characterized by unhealthy eating behaviors and concerns about shape, weight, and/or maintaining control over eating. Eating disorders a ect people of all ages, races, ethnicities, sexual orientations, gender identities, income levels, and countries of origin. Eating disorders are common; for instance, recent research found that one in five college students has an eating disorder [ ]. This rate is similar to rates of anxiety and depression, which many people incorrectly think are more common than eating disorders.
People with eating disorders experience many physical, social, and psychological problems (Figure ). Physically, people with eating disorders are at a higher risk for medical conditions, including heart problems (such as heart attacks), metabolic disorders (such as diabetes), and reduced bone density (including osteoporosis). Some people with eating disorders will have a very low body mass index BODY MASS INDEX (BMI) BMI is an estimate of one's body fat that is calculated using one's height and weight [BMI = weight (in kilograms) divided by the square of the body height (in meters)]; larger BMIs are thought to indicate greater estimated body fat.
(BMI). BMI estimates one's body fat, taking into account one's height (in kilograms) and weight (in meters); larger BMI numbers indicate greater estimated body fat. Socially, the shame and guilt that come with eating disorders may result in isolation. Psychologically, people with eating disorders commonly experience levels of anxiety and depression that make it di cult for them to function normally. Eating disorders have the highest mortality rate of any mental illness, due to medical complications caused by the eating disorder and/or death by suicide. Thus, preventing the development of eating disorders and providing e ective treatment is very important.

EATING DISORDER DIAGNOSES
The ( ) Anorexia nervosa (AN) is characterized by extreme restriction of food intake that results in a significantly low body weight (BMI < . kg/m ). Behaviorally, extreme dieting is the main symptom of AN, but people with AN may also use the following methods to control weight: excessive exercise, taking laxatives and/or diuretics (substances that

LAXATIVES AND DIURETICS
Any substance that may be used to increase the frequency of defecation (laxatives) or urination (diuretics). cause increased defecation or urination), using diet pills or teas, and/or making themselves vomit. People with AN experience distressing thoughts, such as intense fears of weight gain and feeling fat even when underweight. People with AN may view being at a certain weight or wearing a certain clothing size as the biggest contributors to their self-worth, above other, more common factors, such as friendships, academic performance, and hobbies. A challenge with AN is that many people with the illness may not understand the seriousness of their symptoms. For instance, they may deny the negative e ects that their eating behaviors and low weight have on their health. compensatory behaviors at least once per week for months; and

COMPENSATORY BEHAVIOR
Any behavior used to counteract the e ects of eating or to influence body weight or shape, such as making oneself vomit, using laxatives and/or diuretics to lose weight, excessive exercise (i.e., > h), severely restricting food intake, and fasting for non-religious purposes (going more than h without eating or skipping meals).
( ) body image concerns. Binge eating occurs when a person eats a very large amount of food in a short amount of time and feels like they are out-of-control over their eating. A "very large" amount of food is commonly defined by the "pint plus" rule. That is, when a person eats a pint of ice cream plus another food item or other, similar amounts of food. People with BN use compensatory behaviors to counteract the e ects of a binge episode and/or to control body shape and/or weight. Compensatory behaviors may include (but are not limited to) exercising excessively, restricting caloric intake, fasting (such as not eating for or more hours), making oneself vomit, and taking laxatives and/or diuretics for weight control. BN can result in serious medical consequences, such as stomach rupture and tooth enamel decay.
( ) Binge eating disorder (BED) is defined as binge eating at least once per week for months without using compensatory behaviors, in people with at least a healthy BMI. To be diagnosed with BED, binge eating episodes must be accompanied by at least three of the following symptoms: eating more rapidly than normal; eating until feeling uncomfortably full; eating large amounts of food when not kids.frontiersin.org October | Volume | Article | hungry; eating alone because of feelings of embarrassment about the quantity of food being eaten; or feeling disgusted, depressed, or guilty after binge eating. People with BED often experience physical health and mental health problems, and may also experience teasing and bullying because of their weight.
( ) Other specified feeding and eating disorder (OSFED) is a diagnosis that captures the fact that many people with eating problems do not fit into the categories of AN, BN, or BED. OSFED is the most common, and diverse, eating disorder diagnosis. For example, someone who has an OSFED may meet all criteria for AN, except their BMI is between . and . kg/m . Similarly, someone with at least a healthy weight may engage in binge eating or compensatory behaviors, but not at the frequency necessary for a BN or BED diagnosis. Although a person diagnosed with an OSFED does not fully meet the criteria for AN, BN, or BED, it does not mean that their eating disorder is not real or that it is not serious. The distress, risk of suicide, and medical complications associated with OSFED are equal to, and sometimes higher than, AN, BN, and BED.

MYTHS ABOUT EATING DISORDERS
One of the most common and harmful myths about eating disorders is that they only happen to young, wealthy, heterosexual, white, non-transgender girls, and women [ ]. This myth is so engrained in our society that a famous study showed that mental-health clinicians sometimes dismiss eating disorder symptoms reported by someone who is not white [ ]. This myth is harmful because many people who have eating disorders go unidentified and never get treatment. Recent research using samples of people from around the world have busted this myth by showing that eating disorders a ect individuals of all ages, genders, sexual orientations, races, ethnicities, and socioeconomic statuses [ ].
Another harmful myth is that a person must be underweight to have an eating disorder. In reality, most people with eating disorders are not underweight and eating disorders happen to people of all body shapes and sizes [ , ]. A related myth is that if a person is not underweight, their eating disorder is not severe. Although being underweight is medically unsafe, people with eating disorders who are not underweight can have serious health issues that cannot be seen with the naked eye, such as electrolyte imbalances, digestive problems, and/or cardiac issues [ , ]. Thus, eating disorders can have lethal health consequences in people of all body sizes.
Yet another harmful myth about eating disorders is that they are a choice. No one chooses to have an eating disorder. We know that eating disorders begin from complex interactions of biology with social, cultural, and environmental influences [ ]. We do not have all WHAT ARE SOME WARNING SIGNS?
You might be wondering how to know if you or a friend may be developing an eating disorder, so here are a few warning signs. One major warning sign is dieting or following strict rules about food and exercise, especially if you feel guilty or ashamed when you do not follow your diet, or your rules interfere with your social activities or schoolwork. It is also concerning if you find yourself constantly thinking about food and/or your body. Your friends may approach you about changes they have observed in your eating behaviors. Similarly, you might worry about a friend if they stop eating all the things they once loved. Another warning sign is a decline in performance in school, sports, or other activities. Last, feeling upset by your eating behaviors and/or body image concerns is another warning sign.

HOW TO GET HELP
A first step in seeking help is confiding in someone you trust, such as a teacher, counselor, coach, friend, sibling, parent, or other family member. If you are concerned about a friend, you can start by talking to your friend and asking if they would like help with approaching an adult for support. It is important to be aware that some friends may deny that they have a problem. In this case, it may be helpful to confide in an adult about your concerns for your friend.
