Every day at midpoint in the day will eat 150 calories her lunch: yogurt is low and a handful of fruit. To eat earlier, he felt, would "greedy. " To eat later would interfere with the dinner ritual. Jane's meal was initially becoming more limited in adolescence, when she was worried about the changing body being subjected to puberty. When he first settled in lunch and routine-used a kid's spoon to "make the last yogurt" and water sipping between each bite — he felt accomplished. Jane enjoys the praise of her friends about her "extraordinary will." In the term of behavioral sciences, her actions are a commandment, motivated by producing certain outcomes. In a relatively short, she got the results she really wanted: weight loss.
Years later Jane, now in her 30s and newspaper reporter, kept the same lunch the same way. Curled up in her workspace in the newsroom, she tried to avoid unwanted attention and feared something that might interfere with the routine. He no longer takes pride in his behavior. His friends stopped praising his "self-control " Many years ago, when his weight fell in low dairy. So low that she should be hospitalized on more than one occasion.
Losing a long weight doesn't make her feel better about her or her appearance. Jane's hair, shiny, thick, blunt, skin and eyes are missing brightness. There are other costs as well – for his relationship, for his career. Instead of dreaming about a great romance, Jane dreamed of cupcakes she could not allow herself at her nephew's birthday party. Instead of thinking about the best hints for the next story, she's obsessed over calories and sports.
Jane conducts rituals and approaches for food, her obsession with normal calories and small weight is a common symptom of anorexia nervosa, a dangerous eating disease affecting roughly one of 200 American women. Anorexia is high relapse and ranks among the deadliest of all psychiatric conditions. Individuals with impaired, about 10 percent of them are males, entering a state of hunger that can lead to a variety of medical complications, including heart disease, anemia, bone loss, infertility, and more. A young woman with this disease faced six times the average risk of mortality for someone her age, according to a meta-analysis of 36 studies, and death increased by 5 percent for each decade of illness.
Anorexia nervosa is often misunderstood by the public who tend to glorify openness and the rule-laden view of eating as an envy of self-control. This is no new thing. In the Middle Ages, several religious figures, including Saint Catherine of Siena, were amazed to engage in extreme hunger-the extreme conditions "Holy anorexia." Today we see ourselves starving on behalf of a sanction over the skinny pursuit. But there is nothing glorious about this disease, nor does it give actual size true control. Rigid, routine gradual behavior close to individuals who suffer until life becomes fully about numbers on food labels, or scales, or clothing marks.
A new research line suggests that the essence of the Jane condition – her bottom weight – is not only a matter of self control. It prefers that the routine now happens almost automatically regardless of the outcome. Jane incriminated herself every morning before she took a bath and again before she went to work. On every meal, she reads and is food label rereads for their nutritional details. He cuts the food into small pieces without thinking. In terms of behavioral sciences, his mind is ruled by habit.
Habits can be very useful. They allow minds to multitask and deep thereby allowing efficiency. The behaviour is connected together into a routine, and once the chain action starts, the rest follow with a little mental effort. But sometimes habits take when they are useless. We and others on the field learned that this may be the case with anorexia nervosa.
The habit-based model of the disorder offers a compelling explanation for why patients such as Jane struggle for years through chapters of outpatient and inpatient treatment without finding lasting recovery. If her illness is even partially explained by hijacked habit learning, it suggests that habit-busting techniques could be part of the solution. Habit-reversal therapy, for example, is well supported for conditions such as trichotillomania (hair-pulling disorder) and tic disorders. This type of treatment helps people become more aware of the cues that set their habits in motion and develop competing responses. For example, those with an urge to pull hair might be instructed to occupy their hands by imagining they are squeezing a lemon. We have adapted this approach for patients with anorexia in an intervention called REACH (regulating emotions and changing habits).
Jane worked with us in the REACH framework. The habit hypothesis made sense to her and helped her to feel better about why she had been stuck in routines that she knew were not healthy. We shared with her results from a brain-imaging study, published last year in Nature Neuroscience, that one of us (Steinglass) co-authored. It showed that when people with anorexia nervosa make decisions about what to eat, they use a different part of the brain—the dorsal striatum—than those without eating disorders. Studies in both animals and humans have shown that this deep-brain structure is involved with many aspects of behavior, one of which is habitual behavior.
In individual psychotherapy sessions, we helped Jane identify a number of habits that served the eating disorder better than they served her. At home and work she kept track of these routines and paid attention to their earliest cues. For example, Jane noticed that her mealtime rituals began with washing her hands. In therapy, she identified another action to try when faced with this cue. She began to bypass the sink, altering her route to the dining table. This small change made a difference in the subsequent chain of behaviors. Jane practiced moving her water glass out of arm's reach at the start of a meal; with improved awareness, it became easier to resist taking sips between each bite. Behaviorists refer to this as stimulus control: altering the environment to encourage an alternative behavior. In other instances, Jane developed competing responses—simple, motor-based counteractions—that made it harder to act out of habit. For example, she practiced picking up her utensils with her nondominant hand to help her take bigger and less “perfect” bites.
As new behaviors helped her break old habits, Jane tackled other routines of illness. For years she had kept a written record of what she ate at every meal. Jane decided to switch the location of her food journal, putting it out of her line of sight after meals. Instead of reaching for the journal, she turned to friends and family after eating—by phone or e-mail or in person if possible—which also provided an element of distraction. Nevertheless, this change provoked anxiety. To manage it, her therapist taught her a muscle-relaxation exercise—tensing one muscle at a time and then letting it go.
Most important, Jane learned that reversing or replacing old habits brought good outcomes. This was an essential element because behaviors that are associated with reinforcement grow stronger over time. During meals, Jane felt more present, and she found, to her pleasure, that she could participate more fully in conversation during and after eating. As she spent less time logging calories in her journal, she could focus instead on reading for work and leisure. Breaking these routines felt frightening at first, but loosening the grip of old preoccupations also brought an unanticipated element of relief. Jane's weight slowly improved, and although this change felt scary, she described feeling more motivated and able to maintain her new behaviors because they led to clearly positive rewards.
Encouraged by success with our initial patients, we have begun a small, randomized controlled trial to compare our habit-breaking approach with routine treatment for anorexia nervosa. By linking treatment directly with mechanisms of illness—in this case, the neural circuitry of habit—we hope to better understand this puzzling disorder, improve treatment and free more patients like Jane from the prison of habit.
