UNDER STRESS, BRAINS OF BULIMICS RESPOND DIFFERENTLY TO FOOD

Scans suggest food is a form of escape from self-critical thoughts

WASHINGTON -- Magnetic resonance imaging scans suggest that the brains of women with bulimia nervosa react differently to images of food after stressful events than the brains of women without bulimia, according to research published by the American Psychological Association.

In women with bulimia, the researchers found decreased blood flow in a part of the brain associated with self-reflection, compared with increased blood flow in women without bulimia. This suggests that bulimics may be using food to avoid negative thoughts about themselves, the researchers said. 

“To our knowledge, the current study is the first investigation of the neural reactions to food cues following a stressful event in women with bulimia nervosa,” said lead author Brittany Collins, PhD, of the National Medical Center. The research was published in the Journal of Abnormal Psychology.

Stress is considered to be a trigger for binge-eating in patients with bulimia nervosa, but there is little research on how people with bulimia nervosa process and respond to food cues.
 
The researchers conducted two experiments. In the first, 10 women with bulimia and 10 without came to a lab where they all ate the same meal. After waiting for about an hour and becoming familiar with an MRI scanner, they then entered the scanner and were shown a series of neutral pictures, such as leaves or furniture, followed by a series of high fat/high sugar food pictures, such as ice cream, brownies, pizza or pasta with cheese sauce. 

Participants were then asked to complete an impossible math problem, a task designed to induce stress and threaten their ego. They then re-entered the scanner and looked at different photos of high fat/high sugar foods. After every activity in the scanner, the women rated their levels of stress and food cravings. 

“We found that everyone experienced increased stress after the stress task, and that everyone reported that stress went down after seeing the food cues again. Also, every time that participants saw the food cues, they reported that their craving for food went up,” said co-author Sarah Fischer, PhD, of George Mason University.

What was surprising was even though patterns of self-reported results were similar for both groups, the two groups showed very different brain responses on their MRI scans, Fischer said. For women with bulimia, blood flow to a region called the precuneus decreased. For women without the eating disorder, blood flow to this region increased. The precuneus is involved in thinking about the self.

“We would expect to see increased blood flow in this region when someone is engaged in self-reflection, rumination or self-criticism,” said Fischer.

In the second experiment, the researchers asked 17 women with bulimia nervosa to complete the same task as the women in the first study, in order to examine whether the findings could be replicated in a different sample of women.
 
“Our results were the same in the second study,” said Fischer. “Women reported increases in stress following the stress task and increases in food craving after seeing food cues. More important, blood flow to the same region, the precuneus, decreased when viewing food cues following stress.”

Collins believes that this decreased blood flow in bulimics suggests that the introduction of food shuts down self-critical thinking in bulimics and gives them something to focus on instead of the painful prospect of dealing with their own shortcomings.

Psychologists have previously theorized that binge-eating provides bulimic women an alternate focus to negative thoughts about themselves that may be brought on by stress. This research provides support for this theory, according to Collins.

“Our findings are consistent with the characterization of binge-eating as an escape from self-awareness and support the emotion regulation theories that suggest that women with bulimia shift away from self-awareness because of negative thoughts regarding performance or social comparisons and shift focus to a more concrete stimulus, such as food,” said Collins.

The results of these experiments could also suggest a neurobiological basis for the use of food as a distractor during periods of stress in women with the disorder, she said. The researchers called for further studies to confirm their results, which they termed preliminary.

The article is part of a special section of the July 2017 issue of the journal devoted to outstanding contributions by young investigators in the field of eating disorders.

“This issue is dedicated to highlighting the accomplishments of an impressive group of young researchers,” wrote the section co-editors Pamela Keel, PhD, Florida State University, and Gregory Smith, PhD, University of Kentucky, in their introduction. “The papers offer a glimpse into the many and multifaceted forms of progress young researchers are making in the effort to understand and address an extraordinarily important form of psychopathology, dysfunction related to the basic need of food consumption.”

    Binge Eating Disorder- The cycle that continues to feed itself

    Binge Eating Disorder- The cycle that continues to feed itself

    By: Annyck Besso, MS, RD

    “I woke up the next morning, in distress, telling myself that I needed to have more control over my eating and then everything would be ok.”  This sentence or a similar one may sound familiar to several individuals. In a society that places a great deal of importance on weight loss and healthy eating, most people believe that the problem is related to their “lack of control," rather than something greater. 


    What is Binge Eating Disorder?: 
    Binge Eating Disorder (BED) was first recognized as an eating disorder in the DSM V, which was published in 2013 (APA, 2017). The diagnostic criteria for BED include, but are not limited to, the perception of loss of control while eating a larger quantity of foods than considered “normal” in a specific period of time in addition to extreme feelings of guilt and shame afterwards.  While diagnostic criteria for BED does not include compensation following a binge (e.g., vomiting, laxative use).

    Figure 1- Common nutritional and emotional pattern that arises in many patients with BED

    Figure 1- Common nutritional and emotional pattern that arises in many patients with BED

    Restriction and the Binge Cycle:
    People with BED often report that they try to make up for the behavior the following day through restrictive eating. This restrictive eating behavior can present itself in several forms, such as using food rules to eat “healthier,” avoiding certain foods or limiting oneself to a certain amount of calories. Sometimes just the idea that tomorrow will be different can keep the binge cycle going. 


    The goal of your dietitian is to target restrictive eating, which normally perpetuates the cycle of feeling overly hungry then bingeing. Messages from social media often seem to condition us to believe that we can control what our bodies want and what they should look like. This battle can have dire consequences on our physical health, our mood and our emotional well-being.

     
    Sandra’s Story

    One example is a client who I will name Sandra. Sandra has always had a very difficult relationship with her body,  creating  food rules to try to control her weight and shape. For years, she attempted several diets, which worked initially, but then she ended up heavier and more demoralized after each one. She became confused as she was following her food rules and eating “healthy,”but was unable to lose any weight. Often, Sandra would come home from a long day of work and describe “zoning out” and eating whatever “forbidden foods” she could find over a period of an hour. When she would finally “snap out of it,” she was filled with feelings of guilt, shame and loathing for herself. She would reassure herself by saying that this was the last time and that she was going to get things under control the following day; she would get rid of all the junk food in her house and start anew. 


    While this may seem like a good strategy, this is exactly what I would NOT recommend a client to do. Food rules typically perpetuate the cycle of loss of control(led?) eating. It is not a lack of control that leads to bingeing; it is instead primarily the emotional relationship people have with food and their body (amongst other reasons). 


    Treatment Goals:
    Stopping the cycle: after a binge, do not try to “get back on track”. 
    Reconnecting with your body: try asking yourself how hungry you feel before a meal and how satisfied you feel after a meal. Try to let your body guide your food choices, rather than deciding what it should be having. 


    Accepting all foods: there is no such thing as a good food or bad food. All foods are good and serve different purposes in our lives. Eliminating a food or food group simply makes it novel and more interesting which leads us to become preoccupied with the food. 


    Eliminating mindless eating: if you eat at your desk, in front of the TV or in the car, this one is for you. Take time to just EAT and taste the food you’re putting in your mouth. It will feel much more satisfying. 


    Please note the strategies above are NOT as simple as they may seem. If you can identify with this article or know someone who has an emotional relationship with food, it may be beneficial for them or for you to talk with a Registered Dietitian. Please don’t hesitate to reach out.

    The Downside of Missed Periods

     
    Sam Tryon, MS, RD

    Sam Tryon, MS, RD

     

    For some, the idea of not having their period might be cause for celebration.  No cramps, bloating or having to worry about keeping tampons or pads on hand; awesome right?! Unfortunately, not getting your period could be cause for concern.*

    If you are 16 years old and have not yet started your period or if you have missed at least 3, you could be diagnosed with amenorrhea.1 Amenorrhea can be caused by a variety of factors including genetic abnormalities, gland problems, and certain gynecological conditions.1  Amenorrhea may also be due to what you eat and how active you are.

    The roles of nutrition and activity

    Low energy availability is one cause of amenorrhea.  Energy availability is a measure of the energy left for bodily functions (i.e. heart beating, digestion, breathing) after subtracting for energy used during exercise and other activities of daily living (i.e. vacuuming, walking to work, gardening).  Low energy availability means that there is not enough energy for body functions and exercise.

    Low energy availability can be a result of not taking in enough fuel (A.K.A. not eating enough) and/or using too much energy for exercise.  Among other effects, the lack of energy left for bodily functions leads to decreased production of gonadotropin-releasing hormone, a hormone important in reproduction, which causes decreased production of estrogen and progesterone and disruption of the menstrual cycle.2

    Amenorrhea and Bone Health

    Both low energy availability and reproductive hormone changes have negative impacts on bone density.  In addition to not having the available energy and nutrients to maintain bone mass, lack of estrogen is associated with bone loss.  In a healthy body, our bones are constantly being broken down to release minerals like calcium and then rebuilt.  Without estrogen, there is increased breakdown without rebuilding which leads to decreased bone density.  This can progress to osteopenia and osteoporosis, putting a person at risk for fractures.  

    Studies have found that up to 95% of people with Anorexia Nervosa have osteopenia and as many as 40% have the more severe osteoporosis.3 Weight gain is associated with return of menstruation and possible reversal of at least some bone loss.

    Amenorrhea and bone loss are especially concerning in adolescents as peak bone mass is reached during this time. Bone loss from low energy availability during this stage of life may prevent patients from reaching a normal peak bone mass. This can put them at increased risk for fractures later in life.

    Next Steps

    If you have missed 3 or more periods, an appointment with your general physician can help to determine the cause of amenorrhea.  They may recommend a bone density test to look for possible bone loss.  

    If the cause is found to be nutrition related, a dietitian can help you change your diet to make sure you are taking in enough energy to fuel your body. Amenorrhea can occur with or without disordered eating and a dietitian can also help assess for any disordered eating behaviors.  If disordered eating is a problem, a therapist may be added to the team to best tackle these concerns and get you back to the activities you love.

    Social Anxiety Treatment

    Our Social Anxiety Program is starting March 13th, 2017. Please give us a call for more information. Skills class meets Monday from 5-630pm. 

     

    COMPREHENSIVE CBT (CCBT) FOR SOCIAL ANXIETY

    12 Week Program

     

    What is Comprehensive CBT (CCBT) for Social Anxiety?

    Our 12- week CCBT for Social Anxiety Program includes both individual and skills class (group) formats. The treatment incorporates several strategies in the following contexts:

    • Exposure through Role Plays
    • Cognitive Restructuring Exercises (e.g., identify and evaluate beliefs)
    • Social Skills Training  through Modeling and Coaching

    COMPONENTS OF THE CCBT PROGRAM:

    1. Skills Classes (Group)

    Classes include 6-10 participants and focus on skill acquisition and application in a supportive environment with real-time feedback. Classes are co-led by two therapists. Class is Monday from 5:00-6:30 pm. Sessions 1-2 are an introduction to CBT and social anxiety, sessions 3-4 are devoted to skills training (e.g., initiating, maintaining, and ending conversations, as well as compromise and negotiation), and sessions 5-12 involve exposure simulation, cognitive and behavioral skills acquisition, identification of cognitions, and generalization of skills to multiple contexts.

    2. Individual Therapy

    Patients meet with their individual therapists for several weeks of pre-treatment (before skills class begins) to develop goals, create a hierarchy of fears, and gain preliminary insight into their symptoms. Patients may also inquire about medication options during pre-treatment.

    3. Homework

    Homework is a required and essential part of CCBT for Social Anxiety in order to generalize skills to a variety of contexts. Participants in the program should expect daily homework that will be of increasing "intensity" to help challenge and overcome feared situations. Patients will also complete thought-logs which allow for the evaluation of inaccurate beliefs and development of alternative beliefs.
