Kids who Diet: There’s an App for That, But Shouldn’t Be

WW International, the company formerly known as Weight Watchers, recently launched an app called Kurbo which is designed to help children ages 8-18 to diet and lose weight. The app is marketed as a “health coaching” tool, but a closer look at the company’s website reveals testimonials of children losing weight and dropping BMI points, complete with “before” and “after” photos. In recent years, the words “diet” and “dieting” have been replaced with words like “wellness” and “healthy eating” in popular nomenclature. But more often than not, when people refer to “eating healthy,” they are talking about restricting calories, reducing carbohydrates, and decreasing portion sizes. In other words, dieting in pursuit of weight loss. The brilliant marketing team at Weight Watchers, aware of this cultural shift in nomenclature, re-branded themselves as WW (Wellness that Works) to stay in vogue with their client base: people living in larger bodies.

But make no mistake: Kurbo is a diet app designed to help children lose weight. Although the app is touted as being based on years of scientific research, the very existence of this app defies the best available scientific evidence, which strongly suggests that CHILDREN AND ADOLESCENTS SHOULD NOT DIET.

Why? Let me count the reasons.

  1. Bodies are meant to be diverse in size and shape. The very notion that a child or adolescent should lose weight in order to have an acceptable body flies in the face of genetics and natural size diversity.
  2. Weight loss disrupts crucial physiological processes in the growing bodies of children and adolescents. Puberty requires significant weight gain to ensure proper development of the brain, bones, reproductive organs, and other vital body systems. Losing weight during adolescence can halt puberty, stunt vertical growth, and alter hormone levels.
  3. Dieting is not effective at producing long-term weight loss, but it reliably predicts weight gain and depression. More often than not, dieting leads to weight cycling: losing weight in the short-term but regaining weight and ending up at the same weight, or a higher weight, in the longer-term. Our bodies have evolved to protect us against famine by slowing down metabolic processes when food is scarce (such as, when we are dieting and losing weight) and ramping up hunger signals and cravings, which often leads to overindulgence or binge eating. Weight cycling is associated with negative health outcomes, including increased risk of depression. Individuals who diet frequently experience cycles of shame, guilt, and feelings of failure each time they regain lost weight.
  4. The normalization and glorification of diet culture is harmful and toxic to all children. When a person in a position of authority (e.g., doctor, parent, teacher, coach) tells a child or adolescent to lose weight, or places that child or adolescent on a diet, the message being sent (either subtly or overtly) is: “Your body is not acceptable as it is, and you must work very hard change your body in order to be attractive, healthy, happy, or socially accepted.” This message is damaging to a young person’s self-esteem, confidence, and body image.
  5. Diet culture disproportionately targets and stigmatizes individuals in larger bodies, thus perpetuating weight stigma.
  6. Although dieting itself does not cause eating disorders, dieting (or food restriction of any kind) can trigger the onset of an eating disorder in a child who is genetically vulnerable. Further, diet culture creates a toxic environment for individuals who are recovering from eating disorders. Eating disorders are dangerous, debilitating, difficult to treat illnesses that have the highest mortality rate of any psychiatric disorder.

Thankfully, there are many other individuals and organizations who share my sentiments on this matter and are publicly condemning this app.

  1. Healthcare Providers Against Kurbo. A group of physicians, psychologists, therapists, and dietitians who specialize in treating eating disorders has formed a petition protesting the Kurbo app. You can read and sign the petition here.
  2. Registered Dietitian Christy Harrison published an article in the New York Times explaining why the Kurbo app is harmful to children.
  3. FEAST (Families Empowered and Supporting Treatment for Eating Disorders) posted a position statement condemning this app.
  4. NEDA (National Eating Disorders Association) published a position statement expressing grave concerns about the app.

So, you might ask, if dieting is not the answer, then what should we do about childhood obesity? The answer, based on the best available scientific research, is that obesity per se is not the problem, and thus the pursuit of weight loss per se is not the solution. Instead, adults who are charged with the task of caring for our youth (e.g., parents, teachers, coaches, and doctors) should encourage health-promoting behaviors in children across the weight spectrum. Children of all weights will benefit from eating balanced family meals containing a wide variety of foods from all food groups. Children of all weights benefit from adequate sleep, daily physical activity, and limited screen time. Children of all weights should be taught body acceptance and should be educated about size diversity. This is true health promotion. In some cases, these health-promoting behaviors will result in weight loss for higher-weight children, and in some cases, they will not. But regardless of what happens to the child’s weight, these health-promoting behaviors bring about genuine improvements in the child’s physical and mental well-being. And – this is important – NO HARM IS DONE.

Sorry, WW Kurbo app – you’ve got it all wrong.

Defeating the Monster: Helping Little Girls Overcome Anorexia Nervosa

Over the past two years, I have had an influx of very young girls with Anorexia Nervosa (AN) come to me for treatment. This trend mirrors recent media coverage of the rise in AN among pre-teens. When I tell friends and acquaintances about my work, they are shocked and horrified to learn that many of my AN patients are between 9-12 years old. The typical response is first incredulity, then a remark about how “sad” it is that little girls are under such pressure to be thin and perfect. I am not sad about this at all – in fact, a very young child presenting for AN treatment represents an ideal scenario.

Let me explain. First, there are no good data to support the popular notion that the prevalence of AN has increased over the past few decades (in contrast, the prevalence of bulimia nervosa and binge eating disorder has skyrocketed in recent decades, but that is beyond the scope of this post). Most data in fact suggest that the incidence of AN has remained constant throughout recorded history. Second, we do not yet know how to prevent AN, nor do we know whether AN is possible to prevent.

We do know that children are being diagnosed with and treated for AN at much younger ages now compared to a generation ago. Research has also shown that the prognosis for AN is inversely correlated with age and duration of illness prior to the start of effective treatment. In other words, the younger the patient, the better her chance for full recovery.

The 5th and 6th grade girls who are diagnosed with AN today would most likely have developed AN anyway, but in previous generations the illness would not have been triggered, diagnosed, or treated until later in adolescence, when it is more difficult to treat. Therefore, I view younger age of onset as a positive thing.

AN is triggered by an energy imbalance – that is, a period of time in which a person’s caloric intake is lower than her body’s energy needs. My theory is that kids are developing AN at younger ages because there are more opportunities for energy imbalance to occur in younger children now compared to generations past.

Several factors contribute to this trend of children developing AN at younger ages:

1.) National hysteria about the “obesity epidemic” and well-intentioned but misguided government programs aimed at children.

Children who are predisposed to AN tend to be anxious, sensitive, perfectionistic, rigid, and overly compliant with rules. These are the kids who actually take the “obesity prevention” messages to heart and follow them to the letter. They avoid “unhealthy foods” (e.g., those high in calories) in favor of “healthy foods” (e.g., those low in calories and fat), thus creating a negative energy balance and triggering AN. The irony here is that it is very unhealthy for a growing child to eat a low-fat or restricted-calorie diet.

2.) Earlier puberty.

This generation of children tends to enter puberty earlier than their parents or grandparents. The hormonal changes of puberty, combined with the increased energy needs of the pubertal growth spurt, provide a perfect opportunity for a negative energy balance. Add to that the tendency of girls to begin dieting to counteract their body’s pubertal changes to conform to the thin ideal, and you have a perfect storm.

3.) Participation in intense athletics at younger ages.

It used to be that athletically-inclined kids did not begin intense athletic training until high school. These days, 6-year-old kids begin practicing for their sport multiple nights per week and traveling to games on the weekends. These kids have extremely high energy needs, as they must consume enough food to fuel their sports in addition to keeping up with normal growth and development. Kids who are predisposed to AN are not able to eat enough to fuel their body’s needs. Further, thinness is considered an advantage in many sports such as gymnastics, track and field, cross country, dance, cheerleading, and diving.

4.) Increased stress.

The modern lifestyle is fast-paced, rushed, overscheduled, and pressured for all of us, even children. Every time I listen to an elderly person talk about their childhood, I am struck by how different life was in the 1940’s and ‘50’s and how much more laid back things were for children then. Stress can trigger loss of appetite, which creates a negative energy balance, which can be the beginning of AN in a vulnerable child.

5.) Decrease in family meals.

For a number of reasons, including busy schedules, families are eating together less often now. If a young child is responsible for fixing her own breakfast, packing her own lunch, or microwaving her own dinner, it is much easier for her to skip meals or restrict her food intake without her parents knowing.

6.) Ignorant pediatricians.

In most cases, pediatricians are the first healthcare professionals to spot (or miss) early signs of an eating disorder. I cannot count the number of patients I have seen whose pediatrician was completely unconcerned by a child or adolescent’s weight loss or failure to gain weight. They will often say things such as “Don’t worry, she’s still in the normal weight range for her age” or “she could lose 10 more pounds and still be fine.” Even worse, many pediatricians will congratulate a child for losing weight. It is as if pediatricians have become so consumed with “fighting childhood obesity” that they have forgotten that kids are supposed to grow and gain weight from birth until age 20. Weight loss is not normal or healthy for any child or adolescent. Generations ago, people understood this, and any weight loss in a child was cause for alarm. You know how grandparents always want to feed you a lot, and say “you’re looking thin” as if it were a bad thing?

Like many diseases, AN in children presents differently than in teens or adults. Here are some key differences I have observed in the young children I treat:

1.) Young children are much less likely than teenagers to fall into AN through dieting. In little girls, the negative energy balance is more likely to result from unintentional weight loss through illness, athletic training, or “healthy eating.”

2.) Fear of fat, drive for thinness, and body dysmorphia – which are considered the hallmark cognitive symptoms of AN – are often absent in young children. Eating provokes extreme fear and resistance, but they often cannot articulate why.

3.) Young children are more likely to present with dehydration as well as malnourishment. Whereas teenage anorexics drink large quantities of water, diet soda, and black coffee, little kids sometimes cannot grasp the concept of calories. Many little kids with AN will fear and avoid anything that enters the mouth- including water, gum, vitamins, and medicine.

4.) Teens and adults with AN usually have a list of “safe foods” which are low calorie and low fat – such as salads, fruit, rice cakes, and nonfat yogurt – and they tend to fear high calorie foods such as ice cream and pizza. However, sometimes young children’s food rules and food fears make no caloric sense. For example, I have worked with children who will willingly consume any beverage, including milkshakes, but who refuse to take a bite of solid food, even a carrot stick. Other kids will have a narrow list of safe foods which are familiar but not low-calorie (e.g., chicken nuggets, pop tarts, and grilled cheese sandwiches).

5.) Young children become medically and mentally unstable much more quickly than teenagers. Post-pubescent teen girls and women, even slender ones, start out at a higher body mass and have reserves of fat. Prepubescent children are already light and very lean. A loss of even a few pounds is enough to cause severe medical problems and extreme cognitive distortions in a child. It is not uncommon for a child to go away to summer camp completely healthy and return three weeks later in grave danger.

6.) It is easier for young children to externalize their illness. They often describe feeling “taken over” by a voice or by some evil force beyond their control. They love to name their illness and refer to it in the third person, unlike teenagers who tend to balk at this exercise, or who experience their illness as more ego-syntonic. My young patients have come up with various names for their illness – the monster, the beast, the devil, Scary Larry, and Voldemort are a few that come to mind.

In my experience, young children tend to make a full recovery more quickly and more easily than teens or young adults. Because they fall into AN so quickly and because they are still so dependent on their parents, they are brought into treatment very early in the course of the illness. Their AN thoughts and behaviors are not as engrained as, say, a 16-year-old who has suffered from AN for two years.

Young children are more dependent on their parents than teens. Thus, it is far easier for both parent and child to adjust to the “magic plate” technique of parents preparing and supervising all meals and snacks – this is not so different from what most parents do for their healthy 10-year-olds anyway. It is extremely difficult for teens and especially young adults to accept the amount of parental support and supervision required for successful re-feeding.

I love treating little girls with AN. Each time I get a call from a terrified parent whose little girl who is showing signs of AN, I breathe a sigh of relief, grateful that they have come to my attention so early in the course of the illness. Although these children and their families are in for a harrowing journey, I have complete confidence that they will defeat the monster. These kids can enter their teen years fully recovered and able to enjoy high school and college unencumbered by this horrible illness.
