(HealthDay)—In a mouse model, calorie-restricted weight loss reverses the high-fat diet-induced ghrelin resistance that may contribute to rebound weight gain, according to research published online Jan. 10 in Endocrinology. http://medicalxpress.com/news/2013-01-calorie-restricted-weight-loss-ghrelin-sensitivity.html Health Mon, 21 Jan 2013 13:10:01 EST news277994647 (HealthDay)—When it comes to eating pasta, bread and potatoes, timing could be everything. http://medicalxpress.com/news/2012-12-carbs-dinnertime-weight.html Overweight and Obesity Thu, 13 Dec 2012 11:30:02 EST news274618761 A new study suggests that increasing the amount of sleep that adults get could lead to reduced food intake, but the hormonal process differs between men and women. http://medicalxpress.com/news/2012-10-duration-affects-hunger-differently-men.html Health Wed, 31 Oct 2012 16:52:11 EST news270921125 Researchers at The Scripps Research Institute have found new links between a protein that controls our urge to eat and brain cells involved in the development of alcoholism. The discovery points to new possibilities for designing drugs to treat alcoholism and other addictions. http://medicalxpress.com/news/2012-09-scientists-protein-linked-hunger-implicated.html Psychology & Psychiatry Fri, 14 Sep 2012 09:49:40 EST news266834974 Ghrelin is a hormone released by the lining of the stomach that promotes feeding behavior. Decreasing ghrelin levels could potentially help combat obesity—in fact, a vaccine that lowers ghrelin levels in order to reduce appetite is being studied as a treatment for obesity. http://medicalxpress.com/news/2012-09-ghrelinreducing-appetite-stress.html Psychology & Psychiatry Thu, 13 Sep 2012 13:20:02 EST news266760198 A pre-diet measurement of two hormones related to weight regulation can help predict which dieters will be more likely to maintain their weight loss and who will not, according to a new study. The results will be presented Sunday at The Endocrine Society's 94th Annual Meeting in Houston. http://medicalxpress.com/news/2012-06-ratio-appetite-regulating-hormones-marker-successful.html Overweight and Obesity Mon, 25 Jun 2012 10:40:01 EST news259838524 Can lack of sleep make you fat? A new paper which reviews the evidence from sleep restriction studies reveals that inadequate sleep is linked to obesity. The research, published in a special issue of the The American Journal of Human Biology, explores how lack of sleep can impact appetite regulation, impair glucose metabolism and increase blood pressure. http://medicalxpress.com/news/2012-04-lack-linked-obesity-evidence.html Health Tue, 17 Apr 2012 10:31:35 EST news253877485 New research reveals a fascinating and unexpected molecular partnership within the brain neurons that regulate appetite. The study, published by Cell Press in the January 26 issue of the journal Neuron, resolves a paradox regarding a receptor without its hormone and may lead to more specific therapeutic interventions for obesity and disorders of dopamine signaling. http://medicalxpress.com/news/2012-01-appetite-accomplice-ghrelin-receptor-dopamine.html Neuroscience Wed, 25 Jan 2012 12:00:05 EST news246709320 Max Planck researchers have proven something scientifically for the first time that laypeople have always known: the mere sight of delicious food stimulates the appetite. A study on healthy young men has documented that the amount of the neurosecretory protein hormone ghrelin in the blood increases as a result of visual stimulation through images of food. As a main regulator, ghrelin controls both eating behaviour and the physical processes involved in food metabolism. These results show that, in addition to the physiological mechanisms for maintaining the body's energy status, environmental factors also have a specific influence on food consumption. Thus, the pervasive presence of appetising food in the media could contribute to weight increase in Western populations. http://medicalxpress.com/news/2012-01-external-stimuli-hormonal-behavior.html Health Thu, 19 Jan 2012 10:11:21 EST news246190263 Non-invasive imaging detects prostate cancer earlier than ever before, but can't accurately distinguish between malignant and benign disease.
