(HealthDay)—Young students are more likely to choose healthier school lunches if they can preorder them, away from the temptations of the sights and aromas of food in the lunchroom, a new study finds. http://medicalxpress.com/news/2013-05-preordered-school-lunches-healthier.html Pediatrics Fri, 03 May 2013 15:40:27 EST news286814415 A study published in the most recent version of the journal Obesity found that the body's internal clock, the circadian system, increases hunger and cravings for sweet, starchy and salty foods in the evenings. 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 (Medical Xpress)—It's common knowledge that a child who misses a meal can't concentrate in school.

New research published in BioMed Central's open access journal Flavour shows that subtle manipulations of texture and creamy flavour can increase the expectation that a fruit yoghurt drink will be filling and suppress hunger regardless of actual calorific content. http://medicalxpress.com/news/2012-10-flavor-texture-full-food.html Health Tue, 30 Oct 2012 20:30:01 EST news270839255 Researchers at the Sahlgrenska Academy, University of Gothenburg, Sweden, have identified a molecule in the immune system that could affect hunger and satiety.

During single sittings, these over-eaters consume large servings of high-caloric foods. Sufferers contend with weight gain and depression including heart disease and diabetes. A new clinical trial, called Regulation of Food Cues, at UC San Diego Health System, aims to treat binge eating by helping participants to identify real hunger and to practice resistance if the stomach is full. http://medicalxpress.com/news/2012-02-clinical-trial-binge-eaters-toss.html Health Fri, 10 Feb 2012 06:17:54 EST news248077030 Synaptic plasticity – the ability of the synaptic connections between the brain's neurons to change and modify over time -- has been shown to be a key to memory formation and the acquisition of new learning behaviors. Now research led by a scientific team at Beth Israel Deaconess Medical Center (BIDMC) reveals that the neural circuits controlling hunger and eating behaviors are also controlled by plasticity. http://medicalxpress.com/news/2012-02-scientists-delve-brain-roots-hunger.html Neuroscience Wed, 08 Feb 2012 12:00:11 EST news247918370 (Medical Xpress) -- It’s been said that there are two kinds of eating: eating to survive, or satisfy hunger, and eating for pleasure. The pathways in the brain that control each urge have been studied independently. But now, research by Howard Hughes Medical Institute investigator Jeffrey M. Friedman of Rockefeller University provides evidence that the two pathways are closely intertwined. http://medicalxpress.com/news/2011-11-hunger-hormones-food-appeal.html Neuroscience Fri, 25 Nov 2011 11:30:02 EST news241441253 For the first time, scientists report a link between eating nuts and higher levels of serotonin in the bodies of patients with metabolic syndrome (MetS), who are at high risk for heart disease. Serotonin is a substance that helps transmit nerve signals and decreases feelings of hunger, makes people feel happier and improves heart health. It took only one ounce of mixed nuts (raw unpeeled walnuts, almonds and hazelnuts) a day to produce the good effects. The report appears in ACS' Journal of Proteome Research. http://medicalxpress.com/news/2011-11-benefits-nut-consumption-people-abdominal.html Health Wed, 02 Nov 2011 11:53:44 EST news239453613 Over 17 million US households -- or 14.5 percent -- were unable to eat properly in 2010, either due to small portions, or chronically unhealthy diets, a government report said Wednesday. http://medicalxpress.com/news/2011-09-million-households-lack-proper-diet.html Health Wed, 07 Sep 2011 17:45:01 EST news234636290 Do you always get popcorn at the movies? Or snack while you're on the couch watching television? A new paper by USC researchers reveals why bad eating habits persist even when the food we're eating doesn't taste good. The study also reveals the surprisingly simple ways we can counter our habits to gain control over what we eat. http://medicalxpress.com/news/2011-09-habit-bad-food-easy-swallow.html Psychology & Psychiatry Thu, 01 Sep 2011 13:45:39 EST news234103511 A report in the August issue of the Cell Press journal Cell Metabolism might help to explain why it's so frustratingly difficult to stick to a diet. When we don't eat, hunger-inducing neurons in the brain start eating bits of themselves. That act of self-cannibalism turns up a hunger signal to prompt eating. http://medicalxpress.com/news/2011-08-diets-dont-starved-brain-cells.html Medical research Tue, 02 Aug 2011 12:21:15 EST news231506417 Researchers have found a new way to control the amount we eat: use a bigger fork. While numerous studies have focused on portion sizes and their influence on how much we eat, researchers Arul and Himanshu Mishra and Tamara Masters looked at how bite sizes affect quantities ingested. http://medicalxpress.com/news/2011-07-diners-big-forks.html Health Thu, 14 Jul 2011 12:40:43 EST news229865960 Research to be presented at the upcoming 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, suggests that ghrelin, a naturally occurring gut hormone, increases our willingness to pay for food, while simultaneously decreasing our willingness to pay for non-food items. http://medicalxpress.com/news/2011-07-ghrelin-willingness-food.html Other Tue, 12 Jul 2011 05:22:29 EST news229666935 (PhysOrg.com) -- A new study by Yale University suggests that people's state of mind may influence how physically satisfied they feel after a meal and how likely they are to still feel hungry and consume additional food.
