While the urge to consume more in the evening may have helped our ancestors store energy to survive longer in times of food scarcity, in the current environment of high-calorie food, those late night snacks may result in significant weight gain. http://medicalxpress.com/news/2013-04-triggers-late-night-snack-cravings.html Overweight and Obesity Tue, 30 Apr 2013 09:43:01 EST news286533773 The higher the percentage of people in a city, town or neighborhood with Facebook interests suggesting a healthy, active lifestyle, the lower that area's obesity rate. At the same time, areas with a large percentage of Facebook users with television-related interests tend to have higher rates of obesity. Such are the conclusions of a study by Boston Children's Hospital researchers comparing geotagged Facebook user data with data from national and New York City-focused health surveys. http://medicalxpress.com/news/2013-04-facebook-track-obesity.html Overweight and Obesity Wed, 24 Apr 2013 17:00:10 EST news286037672 (Medical Xpress)—Gastric banding, a common surgery to reduce obesity, leaves much to be desired. Typically, the patient is left with a feeling of constant hunger. Stimulators implanted in the feeding centers of the brain, like the hypothalamus, have met with mixed results. Partly that is to be expected since there is considerable functional overlap within those areas, and also due to the limited resolution that can be obtained with implanted electrodes in bulk brain tissue. Doctors have also tried to stimulate the main trunk of the vagus nerve, the largest nerve in the body. The vagus nerve, however, hits all the major organ systems, not least being the heart. It also provides two-way channels of communication throughout its extent. Researchers in the U.K. , led by Chris Toumazou, have developed a nerve cuff electrode that targets the branch of the vagus that ennervates the gut. The controller can apparently read conditions in the stomach and provide signals of satiety to the brain with proper stimulation. http://medicalxpress.com/news/2013-04-fat-chip-obesity-smart.html Overweight and Obesity Tue, 09 Apr 2013 06:50:02 EST news284707764 Obesity is linked to the widespread epidemics of diabetes and heart disease that plague society, but a lesser-known fact is that the weight can also lead to autoimmune disease. Now, researchers have new information about how that damaging immune response happens and how it might be stopped, published on April 4 in Cell Reports. http://medicalxpress.com/news/2013-04-obesity-health-problems.html Overweight and Obesity Thu, 04 Apr 2013 12:33:40 EST news284297614 How much a person eats may be only one of many factors that determines weight gain. A recent Cedars-Sinai study suggests that a breath test profile of microorganisms inhabiting the gut may be able to tell doctors how susceptible a person is to developing obesity. http://medicalxpress.com/news/2013-03-obesity-linked-microorganisms-gut.html Overweight and Obesity Tue, 26 Mar 2013 00:00:02 EST news283456576 Consumption of foods high in carbohydrates immediately after birth programs individuals for lifelong increased weight gain and obesity, a University at Buffalo animal study has found, even if caloric intake is restricted in adulthood for a period of time. http://medicalxpress.com/news/2013-03-high-carb-intake-infancy-lifelong-effects.html Overweight and Obesity Tue, 19 Mar 2013 13:18:29 EST news282917902 (Medical Xpress)—Richard Wrangham, a primatology professor at Harvard University, in a speech given to an audience at this year's American Association for the Advancement of Science meeting, advocated that changes be made to how calories are shown on food labels. He said that the current method doesn't count the calories in fiber or take into account how much energy the body uses to break down foods. This he said, means consumers aren't getting accurate information. http://medicalxpress.com/news/2013-02-primatologist-caloric-values-food.html Overweight and Obesity Tue, 19 Feb 2013 08:00:01 EST news280477950 Fat is stored in the body in two distinct ways, Yale researchers have discovered.

The findings are published February 13 in the open access journal PLOS ONE by Hans Savelberg and colleagues from Maastricht University, Netherlands. http://medicalxpress.com/news/2013-02-intensity-health-benefits-relative-short.html Overweight and Obesity Wed, 13 Feb 2013 17:20:01 EST news279996988 Whitehead Institute researchers have identified a previously unrecognized layer of genetic regulation that is necessary for the generation of undesirable white fat cells.

So does that mean gastric surgery "cures" diabetes? Not necessarily, according to the largest community-based study of long-term diabetes outcomes after bariatric surgery. For most people in the study, e-published in advance of print in Obesity Surgery, diabetes either never remitted after gastric surgery or relapsed within five years. http://medicalxpress.com/news/2012-11-gastric-bypass-surgery-diabetes-doesnt.html Overweight and Obesity Mon, 26 Nov 2012 15:21:38 EST news273165685 Young children who attend daycare on a regular basis are 50% more likely to be overweight compared to those who stayed at home with their parents, according to a study by researchers at the University of Montreal and the CHU Sainte-Justine Hospital Research Centre. "We found that children whose primary care arrangement between 1.5 and 4 years was in daycare-center or with an extended family member were around 50% more likely to be overweight or obese between the ages of 4-10 years compared to those cared for at home by their parents," said Dr. Marie-Claude Geoffroy, who led the study. "This difference cannot be explained by known risk factors such as socioeconomic status of the parents, breastfeeding, body mass index of the mother, or employment status of the mother." http://medicalxpress.com/news/2012-11-daycare-benefits-children-mysterious-link.html Overweight and Obesity Sun, 18 Nov 2012 11:09:28 EST news272459350 (Medical Xpress)—Neither genes nor the environment alone can predict obesity in children, but when considered together a strong relationship emerges, according to researchers at Penn State, St. Luke's Roosevelt Hospital and the Albert Einstein College of Medicine. The researchers found that children who have a genetic variant that makes them less sensitive to the taste of certain bitter compounds, also called "non-tasters," were significantly more likely to be obese than children who were "tasters" of these compounds—but only when they lived in an unhealthy food environment. http://medicalxpress.com/news/2012-11-interaction-genes-environment-obesity-children.html Overweight and Obesity Thu, 01 Nov 2012 06:52:46 EST news270971554 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? http://medicalxpress.com/news/2012-10-mastering-weight-maintenance-skills-embarking-diet.html Overweight and Obesity Tue, 30 Oct 2012 12:50:01 EST news270818690
