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.

Low-carb diets may burn the most calories nbcnews.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 nbcnews.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
The gut-wrenching dangers of the Western diet The Globe and Mail (Jun. 14 2012) by Paul Taylor – The human gut is literally teeming with billions of “friendly” bacteria that aid digestion and help ward off dangerous pathogens. But a new study suggests the modern Western diet, which is high in saturated fats, could disrupt this delicately balanced microbial community and set the stage for certain diseases. 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
Dieting companies now targeting men cnn.com (Mar 23, 2012) by Emma Lacey-Bordeaux & Gavin Godfrey – Jeff Romig kept putting it off. He knew the doctor would give him bad news. He’d known it for years; he needed to lose weight. But as he sat in the doctor’s office a few weeks ago and listened to his numbers — cholesterol and blood pressure, both too high — he resolved to change. This time, he decided to do something different, something drastic. After 10 years of talking about losing weight without much success, Romig decided to put his health and family first by leaving his high-pressure politics job. 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 nbcnews.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.

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.

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? According to the Canadian Dietary Reference Intakes (DRIs), older adults have the same protein needs as younger ones. 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 nbcnews.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
Fat epidemic linked to chemicals run amok nbcnews.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. What did I do wrong? Link
‘Spoonful of sugar’ makes the worms’ life span go down ScienceDaily (Nov. 5, 2009) — If worms are any indication, all the sugar in your diet could spell much more than obesity and type 2 Diabetes.

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
Do high-fat diets make us stupid and lazy? Physical and memory abilities of rats affected after 9 days ScienceDaily (Sep. 5, 2009) — Rats fed a high-fat diet show a stark reduction in their physical endurance and a decline in their cognitive ability after just nine days, a study by Oxford University researchers has shown. The research, funded by the British Heart Foundation and published in the FASEB Journal, may have implications not only for those eating lots of high-fat foods, but also athletes looking for the optimal diet for training and patients with metabolic disorders.

When parents try to control every little bite: Being too restrictive about your child’s diet can backfire, experts say nbcnews.com (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. The study tracked 200 girls for 10 years from age 5. Link

Exercise not likely to rev up your metabolism: Studies bust myth that working out gives you a fat-burning boost nbcnews.com (May 26, 2009) by Jacqueline Stenson — Start exercising and you’ll become a round-the-clock, fat-burning machine, right? 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
