Brain thinks yo-yo dieting is a famine, causing weight gain  MNT Medical News Today  (Dec 5, 2016) by Marie Ellis – We are in the height of holiday season, when chocolate, cakes, and calorie-laden foods are in abundance. But after the feast has commenced, you may want to think twice before going on a low-calorie diet. According to new research, the brain interprets repeated dieting as short famines, prompting the body to store more fat for future food shortages – resulting in weight gain. … more

Weight loss yo-yo: How the gut reverses effects of dieting  CBC.ca (Nov 25, 2016) – Dieting seems to change the microorganisms in the gut so that people gain back weight quickly. Scientists studying yo-yo dieting in mice say the tendency for people to regain excess weight rapidly after successfully slimming may well be due to their microbiome — the trillions of microorganisms in the gut. The researchers found that changes in the gut microbiome that occur when an obese mouse loses weight can persist for many months, and that this contributes to accelerated weight regain later if the diet lapses. … more

Western-style diet linked to state-dependent memory inhibition  ScienceDaily (July 12, 2016) – Obesity may ultimately be a disease of the brain, involving a progressive deterioration of various cognitive processes that influence eating. Researchers have now shown that memory inhibition — the useful ability to ‘block out’ memories that are no longer useful, which depends on a brain area called the hippocampus — is linked to dietary excess. … more

A Neuroscientist Tackles ‘Why Diets Make Us Fat’  NPR National Public Radio (June 7, 2016) by Jean Fain – When Sandra Aamodt talks about dieting, people listen … or, they stick their fingers in their ears and go la, la, la. Aamodt’s neuroscientific take on why diets backfire is that divisive. Aamodt is a neuroscientist, book author and former editor of a leading brain research journal. She also has become a prominent evangelist of the message that traditional diets just don’t work and often leave the dieter worse off than before. And she’s an enthusiastic proponent of mindful eating. … more

High-fat diet can alter the cellular body clock  MNT Medical News Today (Apr 6, 2016) by Yvette Brazier – “It’s not just what you eat, but also when you eat it,” say researchers who suggest that consuming saturated fats at particular times may put internal body clocks out of synch, also causing inflammation. … more

Diverse diets enrich gut microbes  MNT Medical News Today (Mar 17, 2016) by Catharine Paddock – In a paper published in the journal Molecular Metabolism, scientists describe how health is compromised when we reduce the diversity of nutrients in our diet – because of the effect this has on the richness of our gut microbe population. … more

‘Healthy’ foods differ by individual   ScienceDaily (Nov 19, 2015) – Ever wonder why that diet didn’t work? A new study tracking the blood sugar levels of 800 people over a week suggests that even if we all ate the same meal, how it’s metabolized would differ from one person to another. The findings demonstrate the power of personalized nutrition in helping people identify which foods can help or hinder their health goals. … more

Diet beverage drinkers make up the calories by snacking on unhealthy foods   MNT – Medical News Today (Sept 14, 2015) — People who think they are doing the right thing by choosing a diet beverage then do the wrong thing by snacking on sodium, sugar and high-carbohydrate goodies like cookies, ice cream, fries and pastries, new research finds. … 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

The Real Reason You Sabotage Your Diet  Huffington Post (July 9, 2015) by Dr. Christian Turbide – “I’ve heard it all before!” That’s most probably the response you would give me if I were to address diet and lifestyle changes with you.

High fat diet changes gut microbe populations and brain’s ability to recognize fullness ScienceDaily (July 7, 2015) – Have you ever wondered why eating one good-tasting French fry may lead you to eat the whole batch and leave you wanting more? According to a new study with rats, that high-fat indulgence literally changes the populations of bacteria residing inside the gut and also alters the signaling to the brain. The result? The brain no longer senses signals for fullness, which can cause overeating–a leading cause of obesity. more …

Thoughts drive dieting plans but feelings drive dieting behavior, study finds ScienceDaily ( May 5, 2015) – Dieting is a process that involves a plan to change eating behavior and behaving according to that plan.

Five days of eating fatty foods can alter how your body’s muscle processes food ScienceDaily (Apr 14, 2015 ) – After just five days of eating a high-fat diet, the way in which the body’s muscle processes nutrients changes, which could lead to long-term problems such as weight gain, obesity, and other health issues, a new study has found. “Most people think they can indulge in high-fat foods for a few days and get away with it,” said one investigator. “But all it takes is five days for your body’s muscle to start to protest.”  more …

High-fat diet alters behavior and produces signs of brain inflammation ScienceDaily (Mar 26, 2015) – Can the consumption of fatty foods change your behavior and your brain? High-fat diets have long been known to increase the risk for medical problems, including heart disease and stroke, but there is growing concern that diets high in fat might also increase the risk for depression and other psychiatric disorders. A new study raises the possibility that a high-fat diet produces changes in health and behavior, in part, by changing the mix of bacteria in the gut, also known as the gut microbiome. more…

A maternal junk food diet alters development of opioid pathway in the offspring  ScienceDaily (July 30, 2013) – Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, shows that eating a junk-food diet during pregnancy changes the development of the opioid signalling pathway in the baby’s brain and permanently alters the way this system operates after birth.   Link

Diet products contain dangerous drugs, FDA warns   NBC News: Health (June 18, 2013) by Maggie Fox – Fat Zero sounds like a safe, natural product, containing bee pollen and other ingredients like green tea and lotus seed. But it also contains sibutramine, a prescription diet drug that was so dangerous it’s been pulled off the U.S. market, the Food and Drug Administration says.  The FDA issued warnings about a batch of similar slimming products – all claiming to be natural, and all containing not only sibutramine, but phenolphthalein, a laxative that’s also been pulled out of pills because it might cause cancer.  Link

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

Dieting youth show greater brain reward activity in response to food   ScienceDaily (May 2, 2013) — The story is a familiar one: most people are able to lose weight while dieting but once the diet is over, the weight comes back. Many of us can personally attest that caloric deprivation weight loss diets typically do not produce lasting weight loss. Oregon Research Institute (ORI) senior scientist Eric Stice, Ph.D., and colleagues provide results in a recent issue of NeuroImage that further our understanding of how and why most weight loss diets fail and provide a more comprehensive description of the impact of caloric restriction.    Link

Top four reasons why diets fail    Science Daily (Jan. 3, 2013) — The battle of the bulge is on — any movement on the scale yet? “Losing weight is one of the top resolutions made every year, yet only 20 percent of people achieve successful weight-loss and maintenance,” says Jessica Bartfield,MD, internal medicine who specializes in nutrition and weight management at the Loyola Center for Metabolic Surgery & Bariatric Care.   Link

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

Obese brain may thwart weight loss: diets high in saturated fat, refined sugar may cause brain changes that fuel overconsumption   ScienceDaily (Oct. 1, 2012) — “Betcha can’t eat just one!” For obese people trying to lose weight, advertising slogans such as this one hit a bit too close to home as it describes the daily battle to resist high calorie foods.  But new research by Terry Davidson, director of American University’s Center for Behavioral Neuroscience, indicates that diets that lead to obesity — diets high in saturated fat and refined sugar — may cause changes to the brains of obese people that in turn may fuel overconsumption of those same foods and make weight loss more challenging.   Link

Is Alzheimers caused by too much sugar? How the American diet is as bad for our brains as our bodies   AlterNet (Sep. 14, 2012) by Tom Philpott  (Article first appeared in Mother Jones) – Yet  another reason to load up on fruit and veggies—and work to wrest federal farm policy (which encourages the production of cheap sweeteners and fats)—from the grip of agribusiness.    Egged on by massive food-industry marketing budgets, Americans eat a lot of sugary foods. We know the habit is quite probably wrecking our bodiess, triggering high rates of overweight and diabetes. Is it also wrecking our brains?   Link

Eating right between meetings   New York Times (Sept. 3, 2012) by Julie Weed – The stereotype of business trip dining consisted of an artery-clogging succession of meeting-room pastries, oversize restaurant portions and fast food snagged at the airport.

Will starving yourself help you live longer? Maybe not   Reuters (Aug 29, 2012) by Sharon Begley – The longevity diet’s premise is seductively simple: cutting your calorie intake well below your usual diet will add years to your life.   New research published on Wednesday, however, shows the extreme, emaciating diet doesn’t increase lifespan in rhesus monkeys, the closest human relatives to try it in a rigorous, long-running study. While caveats remain, outside experts regarded the findings as definitive, particularly when combined with those from a similar study.   Link

In dieting, magic isn’t a substitute for science   The New York Times: Fitness & Nutrition (July 9, 2012) by Gina Kolata –  Is a calorie really just a calorie?

Dr. Hirsch, who receives no money from pharmaceutical companies or the diet industry, wrote some of the classic papers describing why it is so hard to lose weight and why it usually comes back.   Link

Low-fat, low-carb, or low-glycemic?  Study shows which is best to keep weight off   msnbc.com Health on Today (June 29, 2012) by Joy Bauer – Cutting-edge research from Boston Children’s Hospital suggests that the type of diet you eat may affect your metabolism, a finding that has important implications for weight maintenance. Published in the Journal of the American Medical Association this week, the study looked at three popular diets (low-carb, low-glycemic, and low-fat) to see which combination of fat, carbs, and protein was the best for people trying to maintain a previous weight loss.  Because decreases in metabolism can contribute to weight regain, the researchers aimed to see which eating plan worked best with the body’s internal mechanisms to rev up dieters’ calorie burn and help them keep the weight off.   Link

Low-carb diets may burn the most calories     msnbc.com: Health on Today  (Jun. 26, 2012) by Lauren Cox  – “Burn  more calories than you eat” remains the golden rule of weight loss, but a new study finds that the human body burns calories more efficiently while on certain diets than on others.   Researchers found that overweight people burned 350 more calories a day, on average, when they ate a low-carbohydrate diet, than when they ate a low-fat diet.    Link

Why your diet tanks at night   msnbc.com: Today Health: Prevention (Jun. 22, 2012) by Markham Heid – It’s the same old story: You start out your day with the best of eating intentions but, by lunchtime, that candy bar’s starting to sound really good. And dinner?  Well … your healthy-eating habits tend to break down as the day wears on, finds a new survey by the digital health company Massive Health. Using an app that lets users send in photos of their meals, Massive Health tracked the eating habits of thousands of people over five months. The results? Most of us hit the wall in our daily race to eat well. In fact, the foods you eat for dinner are nearly 16 percent less healthy than what you ate for breakfast. And get this: For every hour that passes during the day, the healthfulness of the foods you eat drops 1.7 percent.  Link

A trained palate: Understanding complexities of taste, smell could lead to improved diet  ScienceDaily (May 30, 2012) — Researchers at Oregon State University have made some fundamental discoveries about how people taste, smell and detect flavor, and why they love some foods much more than others… As an evolutionary survival mechanism, humans are wired to prefer sweet-tasting foods and avoid bitter substances. In the distant past, that helped us avoid poison and find food that provided energy. Now, it just makes us fat.  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. researches, 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

Mindful eating as food for thought  New York Times (Feb. 7, 2012) by Jeff Gordinier – Mindful eating is not a diet, or about giving up anything at all. It’s about experiencing food more intensely — especially the pleasure of it. You can eat a cheeseburger mindfully, if you wish. You might enjoy it a lot more. Or you might decide, halfway through, that your body has had enough. Or that it really needs some salad.  Link

Preference for fatty foods may have genetic roots  ScienceDaily(Feb. 3, 2012) — A preference for fatty foods has a genetic basis, according to researchers, who discovered that people with certain forms of the CD36 gene may like high-fat foods more than those who have other forms of this gene.  The results help explain why some people struggle when placed on a low-fat diet and may one day assist people in selecting diets that are easier for them to follow.  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

Can’t keep the pounds off? It’s your hormones: Australian study shows that dieters are struggling against a persistent biological urge  msnbc.com: 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

Why even resolute dieters often fail  New York Times (Sept. 19, 2011) by Jane E. Brody – If you’ve been trying for years to lose unwanted pounds and keep them off, unrealistic goals may be the reason you’ve failed. It turns out that a long-used rule of weight loss — reduce 3,500 calories (or burn an extra 3,500) to lose one pound of body fat — is incorrect and can ultimately doom determined dieters.  Link

Free radicals crucial to suppressing appetite  ScienceDaily (Aug. 29, 2011) — Obesity is growing at alarming rates worldwide, and the biggest culprit is overeating. In a study of brain circuits that control hunger and satiety, Yale School of Medicine researchers have found that molecular mechanisms controlling free radicals — molecules tied to aging and tissue damage — are at the heart of increased appetite in diet-induced obesity.  Link

Does food act physiologically like a ‘drug of choice’ for some?  ScienceDaily (July 20, 2011) — Variety is considered the “spice of life,” but does today’s unprecedented level of dietary variety help explain skyrocketing rates of obesity? Some researchers think it might…”We’ve known for years that foods – even eating, itself – can trigger release of various brain chemicals, some of which are also involved in what happens with drug addiction and withdrawal. And, as can happen with substance abusers, tolerance or “habituation” can occur, meaning that repeated use (in this case, exposure to a food) is sometimes accompanied by a lack of response (in this case, disinterest in the food). The results of the study… provides a very interesting new piece to the obesity puzzle by suggesting that meal monotony may actually lead to reduced calorie consumption. The trick will be balancing this concept with the importance of variety to good nutrition.”  Link

Pass the spinach? Hardly, if it’s lean muscle you’re after  National Post (May 16, 2011) by Jennifer Sygo – If you’re over 50, do you need more protein in your diet?

But the more we learn about protein’s importance for building and maintaining lean muscle as we age, the more some experts feel the guidelines need a second look.  Link

Lost pounds lead to burst fantasy: For many, expectations of a new life don’t match the reality msnbc.com (April 27, 2010) by Joan Raymond – If thin equals happy, Jen Larsen should be on cloud nine. Larsen, 36, of Ogden, Utah, was the fat child. The fat teen. The fat adult. Four years ago, Larsen hit a high of 316 pounds and when diet after diet failed she opted for bariatric surgery. By all measures, the procedure was textbook perfect. The 5-foot-7-inch Larsen is now a slim 140 pounds.  Life, she says, is simpler: she has more energy; her knees feel better; her back doesn’t hurt. And study after study shows she has slashed her risk for life-threatening health conditions like heart disease, cancer and diabetes. But a funny thing happened on the way to becoming a size 8: No matter how much Larsen shrank, her troubles stayed the same size.  Link

Don’t blame fast food for making you fat:  Fat epidemic linked to chemicals run amok  msnbc.com  (Mar. 8, 2010) – by Stephen Perrine with Heather Hurlock.   It’s not just about calories in versus calories out.  If that were all it took to lose weight — eating a little less and exercising a little more — then weight loss would be as simple as grade-school math: Subtract Y from Z and end up with X.  But if you’ve ever followed a diet program and achieved less than your desired result, you probably came away feeling frustrated, depressed, and maybe a bit guilty.

Alzheimer’s researchers find high protein diet shrinks brain  ScienceDaily (Oct. 21, 2009) — One of the many reasons to pick a low-calorie, low-fat diet rich in vegetables, fruits, and fish is that a host of epidemiological studies have suggested that such a diet may delay the onset or slow the progression of Alzheimer’s disease (AD). Now a study published in BioMed Central’s open access journal Molecular Neurodegeneration tests the effects of several diets, head-to-head, for their effects on AD pathology in a mouse model of the disease. Although the researchers were focused on triggers for brain plaque formation, they also found that, unexpectedly, a high protein diet apparently led to a smaller brain.  Link

That’s long been a commonly held belief among exercisers and fitness experts alike. But a new report finds that, sadly, it’s not very likely.  The notion that exercise somehow boosts the body’s ability to burn fat for as long as 24 hours after a workout has led to a misperception among the general public that diet doesn’t matter so much as long as one exercises…  Link

Molecular link between sleep and weight gain ScienceDaily (May 23, 2009) — There appears to be a link between sleep and weight control, with some studies indicating that sleep disruption can increase weight gain and others that diet affects sleep.

Feeding behaviors in monkeys and humans have ancient, shared roots, Bolivian Rainforest study suggests  ScienceDaily (May 20, 2009) — Behavioural ecologists working in Bolivia have found that wild spider monkeys control their diets in a similar way to humans, contrary to what has been thought up to now. Rather than trying to maximize their daily energy intake, the monkeys tightly regulate their daily protein intake, so that it stays at the same level regardless of seasonal variation in the availability of different foods.  Tight regulation of daily protein intake is known to play a role in the development of obesity in humans, and the findings from this research suggest that the evolutionary origins of these eating patterns in humans may be far older than suspected. Until now it was thought human eating patterns originated in the Palaeolithic era (between 2.4 million and 10,000 years ago).  Link
