Kids Who Are Better at Tasting Sugar Are More Likely to Be Overweight, Study Finds   Time/Living (Dec 15, 2015) by Belinda Luscombe –Being more sensitive to sugar might not be a good thing. Some kids can taste as little as 0.005 teaspoons of sugar in a fluid ounce of water. Others need three teaspoons until they register it. Logic would suggest that the less sugar-sensitive—those who need to add more sugar to get the hit of sweetness—would be more likely to be obese, right? Not according to new research. … more

Eating on the move may trigger weight gain in dieters MNT–Medical News Today (Aug 20, 2015) – While it may be a convenient way to fit lunch into a hectic work schedule, new research published in the Journal of Health Psychology suggests that eating while “on the go” could lead to weight gain and obesity in people who are dieting. The study, conducted by researchers from the University of Surrey in the UK, found that eating while walking could make dieters overeat later on in the day, triggering more overeating than other forms of distraction such as watching TV or chatting with a friend. “This may be because walking is a powerful form of distraction which disrupts our ability to process the impact eating has on our hunger …” more

A Fresh Cry Of Pain: Fat-Shaming In Science   NPR (June 19, 2014) by Barbara J. King — One year ago here at 13.7, I wrote about fat-shaming carried out by a college professor of evolutionary psychology. Ever since, I’ve been more attuned than before to blatant discrimination based on weight and have spotted evidence of fat-shaming in multiple contexts. Recent examples range from the world of opera to popular TV shows (Fargo) and sports, in this case tennis. When people — women, often — are seen and judged primarily by their weight instead of by their talents and actions in the world, the result is often incredibly hurtful. None of us wants to be seen and judged so superficially. Now there’s a fresh cry of pain and it comes again from the world of science and higher education. more …

What Causes Weight Gain   New York Times (June 10, 2014) by Mark Bittman – If I ask you what constitutes “bad” eating, the kind that leads to obesity and a variety of connected diseases, you’re likely to answer, “Salt, fat and sugar.” This trilogy of evil has been drilled into us for decades, yet that’s not an adequate answer. We don’t know everything about the dietary links to chronic disease, but the best-qualified people argue that real food is more likely to promote health and less likely to cause disease than hyperprocessed food. And we can further refine that message: Minimally processed plants should dominate our diets. (This isn’t just me saying this; the Institute of Medicine and the Department of Agriculture agree.)   more …

Always Hungry? Here’s Why     New York Times (May 16, 2014) by David S. Ludwig and Mark I. Friedman – For most of the last century, our understanding of the cause of obesity has been based on immutable physical law. Specifically, it’s the first law of thermodynamics, which dictates that energy can neither be created nor destroyed. When it comes to body weight, this means that calorie intake minus calorie expenditure equals calories stored … The simple solution is to exert willpower and eat less. The problem is that this advice doesn’t work, at least not for most people over the long term … But what if we’ve confused cause and effect? What if it’s not overeating that causes us to get fat, but the process of getting fatter that causes us to overeat? more …

A number that may not add up     NYTimes/Well (Apr 14, 2014) by Jane E.

Eating disorder specialists not immune to weight bias   Reuters  (Oct 3, 2013) by Kathryn Doyle – Even some mental health professionals that treat eating disorders harbor prejudice against the obese, a new study suggests.  “Weight bias has been documented among different groups of health providers like doctors, nurses and medical students, so there is no reason to expect that professionals who treat eating disorders would be immune to the same bias,” lead researcher Rebecca Puhl of the Rudd Center for Food Policy and Obesity at Yale University in New Haven, Connecticut, said.   Link

So-called ‘healthy’ toppings and side dishes sabotage weight loss efforts: Ontario study   National Post (July 25, 2013) by Misty Harris, Postmedia News –  You’ve just been served a large slice of chocolate cake — the kind so unapologetically decadent, you feel your thighs expand just looking at it. Thankfully, though, this particular cake is topped with fresh fruit, which reduces the calorie content and makes it a more healthful choice.  Absurd, right? A new Canadian study, however, shows that’s exactly how we’re approaching eating: thinking that a bad food choice can be cancelled by a good one. In fact, researchers find that people reduce their calorie estimation of an unhealthy indulgence by 16% to 25% when it’s topped with something healthy.  Link

‘Weightism’ increases risk for becoming, staying obese   ScienceDaily (July 24, 2013) — Weight discrimination may increase risk for obesity rather than motivating individuals to lose weight, according to research published July 24 in the open access journal PLOS ONE by Angelina Sutin and Antonio Terracciano from the Florida State University College of Medicine.   The researchers compared the height and weight of over 6000 participants, measured in 2006 and 2010.

Are happy gut bacteria key to weight loss?    Mother Jones (Apr. 22, 2013) by Moises Velasquez-Manoff – Imbalances in the microbial community in your intestines may lead to metabolic syndrome, obesity, and diabetes. What does science say about how to reset our bodies?  … Dr. Paresh Dandona, a diabetes specialist in Buffalo, New York, set out to measure the body’s response to McDonald’s—specifically breakfast. Over several mornings, he fed nine normal-weight volunteers an egg sandwich with cheese and ham, a sausage muffin sandwich, and two hash brown patties … what he observed has informed his research ever since. Levels of a C-reactive protein, an indicator of systemic inflammation, shot up “within literally minutes.” “I was shocked,” he recalls, that “a simple McDonald’s meal that seems harmless enough”—the sort of high-fat, high-carbohydrate meal that 1 in 4 Americans eats regularly—would have such a dramatic effect. And it lasted for hours.   Link

Obese patients trust diet advice from overweight physicians more than normal weight physicians   ScienceDaily (June 4, 2013) — When it comes to taking diet advice from a physician — size matters. This is according to a new study led by a team of researchers at the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins University School of Medicine who examined the impact of primary care physician BMI (body mass index) on their patients’ trust and perceptions of weight-related stigma. They found that overweight and obese patients trust weight-related counseling from overweight physicians more than normal weight physicians and patients seeing an obese primary care physician were more likely to perceive weight-related stigma.   Link

Sticking with smaller goals keeps weight loss on track   ScienceDaily (Jan. 17, 2013) — Losing weight — especially when the goal is to lose double-digit amounts — can seem like a daunting task, but a health and wellness expert at the University of Alabama at Birmingham (UAB) said the key is to take it one step at a time.  “If we set lofty weight loss goals, like 10, 20 or 30-plus pounds, and we don’t make progress quickly enough, it’s too easy to get distracted and have our emotions convince us that the goal is not achievable,” … breaking down goals into smaller, more manageable short-term targets, like losing one to two pounds per week, can lead to better chances of success.      Link

Poll of psychologists cites emotions as top obstacle to successful weight loss     ScienceDaily (Jan. 9, 2013) — When it comes to losing weight, a popular New Year’s resolution for many, people often focus on eating less and exercising more.

Mastering weight-maintenance skills before embarking on diet helps women avoid backsliding   ScienceDaily (Oct. 30, 2012) — Would you take part in a weight-loss program in which you were explicitly asked not to lose any weight for the first eight weeks?  Although the approach sounds counterintuitive, a study from researchers at the Stanford University School of Medicine found that women who spent eight weeks mastering weight-maintenance skills before embarking on a weight-loss program shed the same number of pounds as women who started a weight-loss program immediately. More importantly, the study showed that the “maintenance-first” women had regained only 3 pounds on average a year later, compared to the average 7-pound gain for the immediate dieters.   Link

Is fructose being blamed unfairly for obesity epidemic?      ScienceDaily (Feb. 21, 2012) — Is fructose being unfairly blamed for the obesity epidemic? Or do we just eat and drink too many calories?  Researchers from St. Michael’s Hospital reviewed more than 40 published studies on whether the fructose molecule itself causes weight gain…”Fructose may not be to blame for obesity…It may just be calories from any food source. Over consumption is the issue.”   Link

Study: Doctors over-estimate patients’ ability to lose weight (Feb 21, 2012) by Karen Rowan – If you want to know whether you’ll lose weight or not, don’t ask a doctor.  In a new study, physicians predicted about 55 percent of patients would be “likely” or “very likely” to follow their recommendations for losing weight, eating healthier or getting more exercise. But three months later, only 28 percent of patients had lost at least two pounds, 34 percent were eating less fat and more fiber, and 6 percent were getting in one more hour of brisk walking each week.  Link

The new weight-loss math    The Globe and Mail (Feb. 21, 2012) by Leslie Beck – If you’ve ever followed a weight-loss diet, you might be familiar with the 3,500-calorie rule.  It’s pretty simple: Since there are 3,500 calories in a pound of body fat, eating 500 fewer calories each day – or burning them off exercising – will lead to a slow and steady weight loss of a pound a week. (The math: 500 x 7 days = 3,500).  According to U.S. researchers, this ubiquitous weight-loss rule is overly simple and overly optimistic. And it can lead to unrealistic expectations about how quickly you can achieve a weight-loss goal.  Link

Heavy doctors avoid heavy discussions about weight    NPR’s Health Blog: Shots (Jan. 27, 2012) by Judith Graham – Research already demonstrates that physicians are sometimes uncomfortable talking about weight with their obese patients. Now, a new study shows that the doctors’ weight makes a difference too. Physicians who pack on the pounds discuss weight loss less frequently with obese patients than doctors who have normal body mass indexes.    Link

The naked truth: I let my weight limit my pleasure     Huffpost Women (Jan. 4, 2012) by Rebecca Jane Weinstein – “No man will ever love you,” proclaimed my grandmother in what she considered her infinite wisdom. I was nine or ten — old enough to know exactly what she was talking about, and young enough that I believed her. Thirty-five years later, undergoing the kind of therapy usually prescribed for veterans of war, I understood that she wasn’t entirely right… Growing up overweight, forced to diet early and listen to forecasts of my own spinsterhood, it took me years — years — to say the word “fat.” So you can imagine the complete shift in perspective it took for me to say the words “fat sex.”  Link

A simple weight loss strategy. Really. Maybe.     Huffpost Healthy Living (Jan. 2, 2012) by Wray Herbert – Dieting and weight control are really pretty simple. We gain weight and have trouble losing it because we eat too much and move too little. If we can switch that around, most of us should be able to maintain a sensible weight without resorting to unhealthy gimmicks.  But that’s just the biology of weight control. What about the psychology?    Link

The fat trap    New York Times: Well (Dec. 28, 2011) by Tara Parker-Pope – For 15 years, Joseph Proietto has been helping people lose weight. When these obese patients arrive at his weight-loss clinic in Australia, they are determined to slim down. And most of the time, he says, they do just that, sticking to the clinic’s program and dropping excess pounds. But then, almost without exception, the weight begins to creep back. In a matter of months or years, the entire effort has come undone, and the patient is fat again.  Link

Could obesity change the brain? NPR’s Health Blog: Shots (Dec.28, 2011) by Nancy Shute – The standard advice for losing weight often comes up short for people who are obese. If they switch to a healthful diet and exercise more, they might lose a bit. But the pounds have a way of creeping back on. Now some provocative research suggests that a part of the problem might be that obesity could change the area of the brain that helps control appetite and body weight. Link

Overweight people eat less often. True or false?    Reuters (Nov. 21, 2011) – Overweight adults eat less often than people in the normal body weight range, but still take in more calories and are less active over the course of the day, according to a U.S. study.   Link

Can’t keep the pounds off? It’s your hormones:  Australian study shows that dieters are struggling against a persistent biological urge Associated Press (Oct. 26, 2011) by Malcolm Ritter – Any dieter knows that it’s hard to keep off weight you’ve lost. Now a study finds that even a year after dieters shed a good chunk of weight quickly, their hormones were still insisting, “Eat! Eat! Eat!”  The findings suggest that dieters who have regained weight are not just slipping back into old habits, but are struggling against a persistent biological urge.  “People who regain weight should not be harsh on themselves, as eating is our most basic instinct,” Joseph Proietto of the University of Melbourne in Australia, an author of the study, said in an email.  Link

Get the skinny on shut-eye:  Lack of sleep actually increases appetite and drives people to binge on unhealthy foods (Sept. 15, 2011) by Kate Lunau – Over 13 million Canadians are overweight or obese, but for those trying to shed pounds, giving up on a full night’s sleep for a 5 a.m. gym session might do more harm than good. Lack of sleep actually increases appetite and drives people to binge on unhealthy “comfort foods,” according to Dr. Charles Samuels, medical director of the Calgary-based Centre for Sleep and Human Performance.  Link

‘Gene overdose’ causes extreme thinness    ScienceDaily (Aug. 31, 2011) — Scientists have discovered a genetic cause of extreme thinness for the first time, in a study published August 30 in the journal Nature. The research shows that people with extra copies of certain genes are much more likely to be very skinny. In one in 2000 people, part of chromosome 16 is duplicated, making men 23 times and women five times more likely to be underweight.  Link

Why some obese people are healthier than skinny people (Aug. 15, 2011) by Debra Black – Being fat doesn’t necessarily mean that you’re in poor health.  Or so suggests a study done by Jennifer Kuk, a York University assistant professor in the School of Kinesiology and Health Science in the Faculty of Health.  “Not all obese individuals have poor health,” Kuk told the Star. “Conversely not all normal weight individuals have good health. You can have normal weight individuals who have high blood pressure, diabetes and poor lifestyle.”  Kuk and her team looked at 6,000 obese Americans comparing them to 23,000 healthy individuals.   Link

The thins versus the fats: Is obesity really a health, and a health care, issue?   New York Times: Opinionator (July 30, 2011) by Eric Etheridge – Though the now-twinned issues of race and beer have dominated the week’s storyline, Paul Campos wants you to think about another form of discrimination — fatism. It’s time we “stop harassing people about their weight,” says Campos, author of the “Obesity Myth,” in an interview with Megan McArdle for her Atlantic blog.  It appears that focusing on the idea that being fat actually makes people fatter. At least there’s an extremely strong correlation there. I bet if we stopped demonizing fatness people would actually be a bit thinner. They’d certainly be happier and healthier.  Link

Obese people can suffer from social anxiety disorder due to weight alone    ScienceDaily (July 1, 2011) — A new study from Rhode Island Hospital researchers shows that obese individuals with social anxiety related only to their weight may experience anxiety as severe as individuals with social anxiety disorder (SAD).

When parents try to control every little bite:  Being too restrictive about your child’s diet can backfire, experts say Health (Sept . 3, 2009) by Bridget Murray Law — Driven by concern about childhood obesity or other food anxieties, more nutrition-focused parents are turning into food cops, monitoring every morsel their children eat…In fact, a recent study found that being too restrictive about the foods children eat can cause more weight gain. Researchers from the Center for Childhood Obesity Research at Pennsylvania State University, University Park, found the highest weight gain among girls who considered their parents most restrictive about eating certain foods.

Psychological link between ‘weight’ and ‘importance’    ScienceDaily (Aug. 31, 2009)  —  Weighty.  Heavy. What do these words have to do with seriousness and importance? Why do we weigh our options, and why does your opinion carry more weight than mine?  New research suggests that we can blame this on gravity. Heavy objects require more energy to move, and they can hurt us more if we move them clumsily. So we learn early on in life to think more and plan more when we’re dealing with heftier things. They require more cognitive effort as well as muscular effort.  This leads to the intriguing possibility that the abstract concept of importance is grounded in our very real experience of weight.  Link

Eating quickly and until full triples risk of being overweight ScienceDaily (Oct. 22, 2008) — The combination of eating quickly and eating until full trebles the risk of being overweight, according to a study published on the British Medical Journal website.  Until the last decade or so most adults did not have the opportunity to consume enough energy to enable fat to be stored. However, with the increased availability of inexpensive food in larger portions, fast food, and fewer families eating together and eating while distracted (e.g. while watching TV), eating behaviours are changing, and this may be contributing to the obesity epidemic.  Link
