Weight Loss Goes Sci-Fi: Using Virtual Reality To Lose Weight?
The University of Houston’s Tracey Ledoux, assistant professor of health and human performance, is using an innovative approach to studying food addictions in hopes of finding strategies to assess and treat them.
“There is a growing body of research that shows that consumption of palatable food stimulates the same reward and motivation centers of the brain that recognized addictive drugs do,” Ledoux said. “These cravings are related to overeating, unsuccessful weight loss and obesity.”
Ledoux and Professor Patrick Bordnick, director of the UH Graduate College of Social Work‘s Virtual Reality Lab, will use virtual environments to try to induce food cravings. Bordnick’s body of research has focused on addictive behaviors and phobias and has used virtual reality as a tool to assess and treat them.
In this new investigation, participants will wear a virtual reality helmet to enter a “real -world” restaurant, complete with all the sights, sounds and smells. A joystick will allow them to walk to a buffet, encounter waitstaff and other patrons.
“Virtual reality will allow us to identify food and food-related stimuli of the built, home, school and social environment that cue food cravings, which has public policy, public health and clinical treatment implications,” Ledoux said. “Our study is innovative because it provides a very effective, cost-efficient tool that can be used to increase our understanding of food cravings.”
Ledoux is recruiting normal-weight women who do not have dietary restrictions or are trying to lose weight. Participants will be invited to two appointments, which may last between 30 minutes and an hour, and will receive a small compensation plus a chance to win a Kindle e-reader. For more information contact Tracey Ledoux at 713-743-1870 or TALedoux@uh.edu.
“Obesity is a pervasive and intractable problem with significant public health and economic costs in our society,” she said. “Finding the elements that promote overeating is critical for reversing the dangerous obesity trend.”

Why Do Some Friends Disappear When The Going Gets Tough?
It’s a question that many of us ask when terrible things happen. Where are the people who call themselves your friends when the going gets tough?
This reposted article from Harriet Brown of the New York Times may help you understand some of the possible answers.
Over the last few years, my family has weathered our share of crises. First our younger daughter was hospitalized for a week with Kawasaki disease, a rare condition in children that involves inflammation of the blood vessels, and spent several months convalescing at home. Soon after she recovered, our older daughter landed in the hospital with anorexia, which proved to be the start of a yearlong fight for her life.
Somewhere in the middle of that process, my mother-in-law was given a diagnosis of advanced lung cancer, and died less than 11 months later.
So we’ve had plenty of opportunities to observe not only how we dealt with trauma but how our friends, family and community did, too. For the most part, we were blessed with support and love; friends ran errands for us, delivered meals, sat in hospital waiting rooms, walked, talked and cried with us.
But a couple of friends disappeared entirely. During the year we spent in eating-disorder hell, they called once or twice but otherwise behaved as though we had been transported to Mongolia with no telephones or e-mail.
At first, I barely noticed; I was overwhelmed with getting through each day. As the year wore on, though, and life settled in to a new if unpleasant version of normal, I began to wonder what had happened. Given our preoccupation with our daughter’s recovery and my husband’s mother’s illness, we were no doubt lousy company. Maybe we’d somehow offended our friends. Or maybe they were just sick of the disasters that now consumed our lives; just because we were stuck with them didn’t mean our friends had to go there, too.
Even if they were completely fed up with us, though, they had to know that my husband and I were going through the toughest year of our lives. I would have understood their defection if our friendship had been less close; as it was, I couldn’t stop wondering what had happened.
In the wake of 9/11, two wars and the seemingly ever-rising tide of natural disasters, we’ve come to understand the various ways in which people cope with crisis when it happens to them. But psychologists are just beginning to explore the ways we respond to other people’s traumas.
“We all live in some degree of terror of bad things happening to us,” said Barbara M. Sourkes, associate professor of pediatrics at the Stanford University School of Medicine. “When you’re confronted by someone else’s horror, there’s a sense that it’s close to home.”
Dr. Sourkes works with families confronted with the unfolding trauma of a child’s serious, and possibly fatal, illness. “Other people’s reactions are multifaceted,” she said. “There’s no formula, and it’ll change from person to person.” The only certainty is that traumatic events change relationships outside the family as well as within it.
Often the closer one feels to the family in crisis, the harder it is to cope. “Most people cannot tolerate the feeling of helplessness,” said Jackson Rainer, a professor of psychology at Georgia Southern University who has studied grief and relationships. “And in the presence of another’s crisis, there’s always the sense of helplessness.”
Feelings of vulnerability can lead to a kind of survivor’s guilt: People are grateful that the trauma didn’t happen to them, but they feel deeply ashamed of their reactions. Such emotional discomfort often leads them to avoid the family in crisis; as Dr. Sourkes put it, “They might, for instance, make sure they’re never in a situation where they have to talk to the family directly.”
Awkwardness is another common reaction — not knowing what to say or do. Some people say nothing; others, in a rush to relieve the feelings of awkwardness, blurt out well-intentioned but thoughtless comments, like telling the parent of a child with cancer, “My grandmother went through this, so I understand.”
“We have more of a societal framework for what to say and do around bereavement than we do when you’re in the midst of it,” Dr. Sourkes said. “Families say over and over, ‘It’s such a lonely time and I don’t have the energy to educate my friends and family, yet they don’t have a clue.’ ”
The more vulnerable people feel, the harder it may be to connect. A friend whose son suffered brain damage in an accident told me that the families who dropped them afterward had children the same age as her son. They could picture all too vividly the same thing happening to their children; they felt too much empathy rather than not enough.
That was true for us, too, I realized. The friends who had disappeared had daughters exactly the same age as ours.
Dr. Rainer describes this kind of distancing as “stiff-arming” — creating as much space as possible from the possibility of trauma. It’s magical thinking in the service of denial: If bad things are happening to you and I stay away from you, then I’ll be safe.
Such people often wind up offering what Dr. Rainer calls pseudo-care, asking vaguely if there’s anything they can do but never following up. Or they might say they’re praying for the family in crisis, a response he dismisses as ineffectual at best. “A more compassionate response,” he said, “is ‘I am praying for myself to have the courage to help you.
True empathy inspires what sociologists call instrumental aid. “There are any number of tasks to be done, and they’re as personal as your thumbprint,” Dr. Rainer said. If you really want to help a family in crisis, offer to do something specific: drive the carpool, weed the garden, bring a meal, do the laundry, go for a walk.
I tested that theory recently, when a friend’s mother went through a series of medical crises and moved to an assisted-living facility in our town. Normally, I might have been guilty of pseudo-care, asking if I could do anything but never really stepping up. Instead, I e-mailed her a list of tasks I could do, and asked if any of them would be helpful.
To my surprise, my friend responded by asking if I’d visit her mother on a day she couldn’t. Her mother was glad for the company, and my friend felt reassured, knowing that her mother wasn’t alone.
And I had the chance to do something truly useful for my friend, which in turn let me show her how much I cared about her. The time I spent with her mother turned out to be a gift for me.
Thinking back to my own years of crisis, I wondered why I’d focused on the friends who didn’t come through when so many others had. In retrospect, I wished I’d taken a slightly more Zen-like attitud
“The human condition is that traumatic events occur,” said David B. Adams, a psychologist in private practice in Atlanta. “The reality is that we are equipped to deal with them. The challenge that lies before us is quite often more important than the disappointment that surrounds us.”

Emotional Binge Eating: Dealing With The Emotions Is Just As Important As Dealing With The Eating
This article highlights how Acceptance and Commitment Therapy (ACT) is being integrated into weight loss programs for emotional eaters.
How many times have you, after a particularly hard day, reached for some chocolate or ice cream? It’s common for many people, but for those trying to lose weight, it can be detrimental to their long term success, and most weight-loss programs never even address it.
Researchers at Temple’s Center for Obesity Research are trying to figure out the answer as part of a new, NIH-funded weight loss study. The new treatment incorporates skills that directly address the emotional eating, and essentially adds those skills to a state-of-the art behavioral weight loss treatment.
“The problem that we’re trying to address is that the success rates for long-term weight loss are not as good as we would like them to be,” said Edie Goldbacher, a postdoctoral fellow at CORE. “Emotional eating may be one reason why people don’t do as well in behavioral weight loss groups, because these groups don’t address emotional eating or any of its contributing factors.”
The study has already had one wave of participants come through, and many participants have seen some success in the short term, but have also learned the skills to help them achieve long term success.
Janet Williams, part of that first cohort, said she lost about 17 pounds over 22 weeks, and still uses some of the techniques she learned in the study to help maintain her weight, which has not fluctuated.
“The program doesn’t just help you identify when you eat,” said Williams. “It helps you recognize triggers that make you eat, to help you break that cycle of reaching for food every time you feel bored, or frustrated, or sad.”
Williams said that the program teaches various techniques to help break that cycle, such as the “conveyor belt,” in which participants, when overcome with a specific emotion, can recognize it and take a step back, before reaching for chips or cookies, and put those feelings on their mental “conveyor belt” and watch them go away.
“I still use the skills I learned in the study,” she said. “I’ve learned to say, ‘I will not allow this emotional episode to control my eating habits.'”

Fast Food, Fast You! How Fast Food Makes You Impatient
Like it or not, the golden arches of McDonalds are one of the most easily recognised icons of the modern world. The culture they represent is one of instant gratification and saved time, of ready-made food that can be bought cheaply and eaten immediately. Many studies have looked at the effects of these foods on our waistlines, but their symbols and brands are such a pervasive part of our lives that you’d expect them to influence the way we think too.
Read the original research paper (PDF)
And so they do – Chen-Bo Zhong and Sanford DeVoe have found that fast food can actually induce haste and impatience, in ways that have nothing to do with eating. They showed that subliminal exposure to fast food symbols, such as McDonalds’ golden arches, can actually increase people’s reading speed. Just thinking about these foods can boost our preferences for time-saving goods and even nudge us towards financial decisions that value immediate gains over future returns. Fast food, it seems, is very appropriately named.
Zhong and DeVoe asked 57 students to stare at the centre of a computer screen while ignoring a stream of objects flashing past in the corners. For some of the students, these flashes included the logos of McDonald’s, KFC, Subway, Taco Bell, Burger King and Wendy’s, all appearing for just 12 milliseconds. We can’t consciously recognise images that appear this quickly and, indeed, none of the students said that they saw anything other than blocks of colour.
The students were then asked to read out a 320-word description of Toronto and those who had subconsciously seen the fast food logos were faster. Even though they had no time limit, they whizzed through the text in just 70 seconds. The other students, who were shown blocks of colours in place of the logos, took a more leisurely 84 seconds.
Zhong and DeVoe also found that thoughts of fast food could sway students towards more efficient, time-saving products. They asked 91 students to complete a marketing survey by saying how much they wanted each of five product pairs. One option in each pair was more time-efficient (as rated by an independent panel of 54 people), such as 2-in-1 shampoo rather than regular shampoo or a four-slice toaster versus a one-slice one.
If the students had previously thought about the last time they ate at a fast food joint, they were more likely to prefer the time-saving products that students who had thought about their last visit to the grocery store. Zhong and DeVoe say that this supports their idea that thinking about fast-food makes people impatient. [This seems to be] the weakest part of their study, for products like 2-in-1 shampoo are as much about saving money (perhaps more so) as they are about saving time. Fast food is not only served quickly but priced cheaply, and it may be this aspect that altered the students’ preference.
However, the duo addressed this issue in their third experiment. They randomly asked 58 students to judge one of four different logos on their aesthetic qualities, including those of McDonald’s, KFC and two cheap diners. Later, they were told that they could either have $3 immediately or a larger sum in a week. They had to say how much it would take to make them delay their windfall.
As predicted, those who considered the fast food logos were more impatient, and demanded significantly more money to forego their smaller immediate payment in favour of a larger future one. It seems that they put a greater price on instant gratification over larger future returns
Of course, these results can’t tell us if fast food actually contributes to a culture of impatience and hurry, or if it’s just a symptom of it. Nor do they say anything about whether this effect is good or bad. That would all depend on context. As Zhong and DeVoe note, a brisk walking speed is a good thing if you’re trying to get to a meeting but it would be a sign of impatience if you’re aiming for a leisurely stroll in the park.
Their study does, however, suggest that fast food and the need to save time are inextricably linked in our minds so that even familiar brands can make us behave more hastily. They could even affect our economic decisions, harming our finances in the long run. As Zhong and DeVoe say, even our leisure activites are “experienced through the coloured glasses of impatience” and “it is possible that a fast food culture that extols saving time not only changes the way people eat, but also fundamentally alters the way they experience events”

Binge Eating: A 12 Week Self-Guided Program Gets Great Results
Kaiser Permanente Center for Health Research, Press Release
Short-Term Program for Binge Eaters Using “Overcoming Binge Eating” by Dr. Christopher Fairburn Has Long-Term Benefits
PORTLAND, Ore. — A new study finds that a self-guided, 12-week program helps binge eaters stop binging for up to a year and the program can also save money for those who participate. Recurrent binge eating is the most common eating disorder in the country, affecting more than three percent of the population, or nine million people, yet few treatment options are available.
But a first-of-a-kind study conducted by researchers at the Kaiser Permanente Center for Health Research, Wesleyan University and Rutgers University found that more than 63 percent of participants had stopped binging at the end of the program — compared to just over 28 percent of those who did not participate. The program lasted only 12 weeks, but most of the participants were still binge free a year later. A second study, also published in the April issue of the Journal of Consulting and Clinical Psychology, found that program participants saved money because they spent less on things like dietary supplements and weight loss programs.
“It is unusual to find a program like this that works well, and also saves the patient money. It’s a win-win for everyone,” said study author Frances Lynch, PhD, MSPH, a health economist at the Kaiser Permanente Center for Health Research. “This type of program is something that all health care systems should consider implementing.”
“People who binge eat more than other people do during a short period of time and they lose control of their eating during these episodes. Binge eating is often accompanied by depression, shame, weight gain, loss of self-esteem and it costs the health care system millions of extra dollars,” said the study’s principal investigator Ruth H. Striegel-Moore, PhD, a professor of psychology at Wesleyan University. “Our studies show that recurrent binge eating can be successfully treated with a brief, easily administered program, and that’s great news for patients and their providers.”
Binge eating has received a lot of media attention recently because the American Psychiatric Association is recommending that it be considered a separate, distinct eating disorder like bulimia and anorexia. This new diagnosis can be expected to focus more attention on binge eating and how best to treat it, according to the researchers. It also could influence the number of people diagnosed and how insurers will cover treatment.
This randomized controlled trial, conducted in 2004–2005, involved 123 members of the Kaiser Permanente health plan in Oregon and southwest Washington. More than 90 percent of them were women, and the average age was 37. To be included in the study, participants had to have at least one binge eating episode a week during the previous three months with no gaps of two or more weeks between episodes.
Half of the participants were enrolled in the intervention and asked to read the book “Overcoming Binge Eating” by Dr. Christopher Fairburn, a professor of psychiatry and expert on eating disorders. The book details scientific information about binge eating and then outlines a six-step self-help program using self-monitoring, self-control and problem-solving strategies. Participants in the study attended eight therapy sessions over the course of 12 weeks in which counselors explained the rationale for cognitive behavioral therapy and helped participants apply the strategies in the book. The first session lasted one hour, and subsequent sessions were 20–25 minutes. The average cost of the intervention was $167 per patient.
All participants were mailed fliers detailing the health plan’s offerings for healthy living and eating and encouraged to contact their primary care physician to learn about more services.
By the end of the 12-week program 63.5 percent of participants had stopped binging, compared to 28.3 percent of those who did not participate. Six months later, 74.5 percent of program participants abstained from binging, compared to 44.1 percent in usual care. At one year, 64.2 percent of participants were binge free, compared to 44.6 percent of those in usual care.
Everyone in the trial was asked to provide extensive information about their binge eating episodes, how often they missed work or were less productive at work, and the amount they spent on health care, weight-loss programs and weight loss supplements. Researchers also examined expenditures on medications, doctor visits, and other health-related services.
The researchers then compared these costs between the two groups and found that average total costs were $447 less in the intervention group. This included an average savings of $149 for the participants, who spent less on weight loss programs, over-the-counter medications and supplements. Total costs for the intervention group were $3,670 per person per year, and costs for the control group were $4,098.
“While program results are promising, we highly encourage anyone who has problems with binge eating to consult with their doctors to make sure this program is right for them,” said study co-author Lynn DeBar, PhD, clinical psychologist at the Kaiser Permanente Center for Health Research.
Study authors include: Lynn DeBar, John F. Dickerson, Frances Lynch and Nancy Perrin from the Kaiser Permanente Center for Health Research in Portland, Oregon; Ruth H. Striegel-Moore and Francine Rosselli from Wesleyan University; G. Terence Wilson from Rutgers, The State University of New Jersey; and Helena C. Kraemer from the Stanford University School of Medicine.
Is Vegetarianism Among Some Teens Possibly Masking an Eating Disorder?
In a recent study published in the Journal of the American Dietetic Association, Dr. Robinson-O’Brien and colleagues examined the link between vegetarianism and a number of health indicators to help us better understand the benefits and risks of vegetarianism in young adults. The authors discussed how vegetarianism is associated with a number of benefits such as increased consumption of fruits and vegetable and lower caloric and energy intake. However, if not done properly, vegetarian diets may also lead to deficiencies in a number of nutrients. In addition, some studies have suggested that teens who have image problems and eating disorders may be more likely to turn to vegetarianism in order to lose weight.
In order to more carefully examine the possible risks and benefits of vegetarian diets in teenagers, the authors collected information from 2,516 teenagers (15 to 18) and young adults (19-23) regarding their eating habits, vegetarian status, weight, dietary quality, physical activity, binge eating practices, healthy and unhealthy weight control behaviors, and substance use.
The authors found that the rate of vegetarianism were relatively low. Only 4% of the teens and young adults stated that they were currently vegetarians, and 11% stated that they used to be vegetarians. Vegetarianism was associated with a number of benefits including:
– lower rates of obesity;
– higher consumption of fruits and vegetables and;
– lower consumption of calories from fat.
However, in the younger cohort, both current and former vegetarians were more likely to engage in more extreme unhealthy weight loss measures and binge eating. Specifically, 20% of current vegetarians and 21% of former vegetarians reported engaging in unhealthy weight loss behaviors, while only 10% of the never vegetarians reported unhealthy weight loss behaviors. Likewise, 21% of current, and 16% of the former vegetarians reported binge eating, while only 4% of the never vegetarians reported engaging in this behavior. Therefore, teen vegetarians were 2 times more likely to engage in unhealthy weight loss behaviors and up to 4 times more likely to engage in binge eating.
In the older group, 27% of former vegetarians reported using unhealthy weight loss measures, which compared to 16% of current vegetarians and 15% of never vegetarians. In addition, 18% of current vegetarians and 10% of former vegetarians engaged in binge eating, compared to only 5% of never vegetarians. Therefore, young adult vegetarians and former vegetarians were more likely to engage in binge eating than never vegetarians, but only the former vegetarians (not the current) were more likely to engage in unhealthy weight control measures.
The authors conclude that although there are some clear benefits of vegetarian diets, in some teenagers and young adults vegetarianism may actually be masking eating problems.
Thus an important issue for parents encountering a teen who wants to become a vegetarian is “why.” It seems less likely (although possible) that vegetarianism is masking an eating disorder in a politically active teen who decides to become vegetarian for well presented philosophical issues related to healthy diets and/or animal rights. However, it would be more concerning if a non-politically active teen with a history of unhealthy eating habits and self-image struggles suddenly decides to become a vegetarian as a form of weight control. Now, this is not necessarily bad, since one could argue that going on a vegetarian diet is a healthy weight loss alternative – one that may actually prevent these kids from engaging in even more unhealthy eating behaviors. However, the danger is that poor vegetarian diets may further compromise the child’s health, especially among adolescents already experiencing nutrient deficiencies due to unhealthy eating habits. Thus the answer may not be to keep your child from starting a vegetarian diet, but instead to make sure that such a diet is carefully monitored, so that the child does not experience further nutrient deficiencies.
Finally, please note that the authors never actually assessed for eating disorders. They assessed unhealthy eating and weigh loss behaviors, which are usually associated with underlying eating disorders. Therefore, contrary to some news reports about this study, this study does not show that vegetarian teens are more likely to have eating disorders than non-vegetarian teens. Instead the data show that vegetarian teens are more likely to engage in unhealthy behaviors that are often associated with eating disorders.
