Poor Sleep Gives You the Munchies, Study Says  New York Times (Mar 4, 2016) by Jonah Bromwich – Evidence has suggested for some time that sleep deprivation can lead to obesity, among a host of other ills. Now researchers are digging into the mechanisms that cause our sleep-deprived brains to crave food they do not need. A study published on Tuesday in the journal SLEEP suggested that the brain receptors that can lead the sleep-deprived to crave unnecessary food were the same as those activated by marijuana. Essentially, not sleeping can give you a ferocious case of the munchies. … more

Sleep loss boosts hunger, unhealthy food choices   ScienceDaily  (Feb 29, 2016) – Cutting  back on sleep boosts levels of a chemical signal that can enhance the pleasure of eating snack foods and increase caloric intake, report investigators.

Food may be addictive: Food craving may be ‘hard-wired’ in the brain   ScienceDaily (Aug 31, 2015) – An international group of researchers have found that food craving activates different brain networks between obese and normal weight patients. This indicates that the tendency to want food may be ‘hard-wired’ into the brain of overweight patients, becoming a functional brain biomarker. … more

Cravings may be reduced with Tetris  MNT-Medical News Today (Aug 17, 2015) – Resisting cravings can be an uphill struggle for many people. However, a new study reveals how playing Tetris may help reduce our desires. In the first study of its kind, psychologists from the University of Plymouth in the UK and Queensland University of Technology in Australia sought to see if the simple tile-laying game could be applied to participants in a real-life setting.

Food craving is stronger, but controllable, for kids   ScienceDaily (Sept 8, 2014) — Children show stronger food craving than adolescents and adults, but they are also able to use a cognitive strategy that reduces craving, according to new research. “These findings are important because they suggest that we may have another tool in our toolbox to combat childhood obesity,” says psychological scientist and the study’s lead researcher. more …

Smoking may dull obese women’s ability to taste fat, sugar   ScienceDaily (Apr 3, 2014) – Cigarette smoking among obese women appears to interfere with their ability to taste fats and sweets, a new study shows. Despite craving high-fat, sugary foods, these women were less likely than others to perceive these tastes, which may drive them to consume more calories. “Obese people often crave high-fat foods,” she said. “Our findings suggest that having this intense craving but not perceiving fat and sweetness in food may lead these women to eat more. Since smoking and obesity are risk factors for cardiovascular and metabolic diseases, the additional burden of craving more fats and sugars, while not fully tasting them, could be detrimental to health.” more …

Habits, not cravings, drive food choice during times of stress   ScienceDaily (July 16, 2013) — Putting a new spin on the concept of “stress eating,” research presented at the 2013 Institute of Food Technologists (IFT) Annual Meeting & Expo® found that people who eat during times of stress typically seek the foods they eat out of habit — regardless of how healthy or unhealthy that food is.  The research co-authored and presented by David Neal, Ph.D., a psychologist and founding partner at Empirica Research, contradicts the conventional wisdom that people who are stressed-out turn to high-calorie, low-nutrient comfort food.   Link

Eating junk food may make you crave even more junk food   Today: Health (June 28, 2013) We know that eating highly-processed carb-heavy foods is not great for us. But we tend to gobble up the food and move on with our lives, telling ourselves we’ll eat healthier at the next meal. But evidence is building that, at least for some of us, our brains don’t quite work that way.  A small study published this week shows that hours after we eat a highly-processed meal with lots of carbohydrates – think white bread, or potato chips – we start to crave more of these junk foods.   Link

Impact of portion size on overeating is hard to overcome   ScienceDaily (Apr. 16, 2013) — People given large servings of food eat more than those given smaller servings, even after they have been taught about the impact of portion size on consumption, research from the University of New South Wales shows.  Learning how to engage in mindful — rather than mindless — eating also did not decrease food intake by a significant amount in those given large servings.   Link

Revealing the scientific secrets of why people can’t stop after eating one potato chip   ScienceDaily (Apr. 11, 2013) — The scientific secrets underpinning that awful reality about potato chips — eat one and you’re apt to scarf ’em all down — began coming out of the bag today in research presented at the 245th National Meeting & Exposition of the American Chemical Society…the results shed light on the causes of a condition called “hedonic hyperphagia” that plagues hundreds of millions of people around the world.  “That’s the scientific term for ‘eating to excess for pleasure, rather than hunger…recreational over-eating that may occur in almost everyone at some time in life. And the chronic form is a key factor in the epidemic of overweight and obesity that here in the United States threatens health problems for two out of every three people.”   Link

Ancient systems in the brain drive human cravings    CBC News (Jan. 2, 2013) by Kelly Crowe – What’s biologically valuable, such as food, water, a sexual partner or social companion, drives the brain’s dopamine system, Richard Beninger tells CBC’s Kelly Crowe.   Neuroscience is the new black, when it comes to fashion in scientific research…Increasingly scientists also believe food can hijack the brain’s reward system. At York University, Professor Caroline Davis is studying the biological basis of food addiction. She says the brain’s reward system can be particularly sensitive to highly processed food with combinations of salt, sugar, fat and flavours found nowhere in nature.   Link

Are bacteria making you hungry?   ScienceDaily (Dec. 19, 2012) — Over the last half decade, it has become increasingly clear that the normal gastrointestinal (GI) bacteria play a variety of very important roles in the biology of human and animals. Now Vic Norris of the University of Rouen, France, and coauthors propose yet another role for GI bacteria: that they exert some control over their hosts’ appetites. Their review was published online ahead of print in the Journal of Bacteriology.

How exercise can prime the brain for addiction  New York Times (Apr. 11, 2012) by Gretchen Reynolds – Statistically, people who exercise are much less likely than inactive people to abuse drugs or alcohol. But can exercise help curb addictions? Some research shows that exercise may stimulate reward centers in the brain, helping to ease cravings for drugs or other substances. But according to an eye-opening new study of cocaine-addicted mice, dedicated exercise may in some cases make it even harder to break an addiction.  Link

Constant cravings:  One in five of us skip breakfast or lunch, and the more we slip, the worse we feel  Macleans.ca (Sept. 15, 2011) by Kate Lunau – Rushing out the door in the mornings, it can be hard to find the time for a decent breakfast, let alone a cup of coffee. According to results from the Symptom Profiler (formerly known as the Q-GAP), an online survey completed by over 29,000 people in 2010-11, skipping meals is fairly common: 23.5 per cent sometimes miss their morning meal; another 6.5 per cent never eat it; 20.6 per cent skip lunch occasionally; and 8.3 per cent miss dinner. But those who skipped meals in this survey also reported more negative symptoms than those who always ate three a day­—and the more meals skipped, the worse shape they were in.  Link

Can’t curb your enthusiasm for food? Blame the brain  CBC News: Food (Apr. 30, 2009) — Next time you give in to that craving for a chocolate bar as your energy levels take a mid-afternoon dip, you could be justified in saying that your brain made you do it. A new study published in the May 1 issue of the journal Science concluded there are differences in the brains of people who are good at controlling their urges versus those who find it almost impossible . . .The research was conducted by scientists at the California Institute of Technology. The study involved dieters, but the scientists say their findings could also be applied to addictions, illegal behaviour and risky financial decisions since each involves willpower.   Link

Rats show the perils of sugar addiction, researchers say  CBC News (Dec. 10, 2008) — Sugar can be addictive, wielding power over the brains of lab animals much like a craving for drugs, according to Princeton University scientists who say their findings may eventually have implications for the treatment of humans with eating disorders.  Psychologist Bart Hoebel and colleagues at the university’s Neuroscience Institute have studied what they call sugar addiction in rats for years.  They say their rats have met two of the three elements of addiction — they show a pattern of increased intake and then signs of withdrawal. But Hoebel’s most recent experiments also demonstrate a third element — craving and relapse.  Link
