Mom's logic was that proper chewing would ease digestion, but the ISU research found that chewing food thoroughly -- 40 times before swallowing -- also reduces food intake in healthy young adults. http://medicalxpress.com/news/2012-04-additional-food-intake-young-adults.html Health Wed, 18 Apr 2012 01:30:01 EST news253930042 US regulators will decide in July whether to approve Qnexa, the first obesity drug in more than a decade, extending the initial deadline by three months, the California-based drug-maker VIVUS said. http://medicalxpress.com/news/2012-04-obesity-drug-july.html Medications Tue, 10 Apr 2012 12:15:20 EST news253278870 Obesity is increasing worldwide in adults and children and is currently viewed by many as one of the most serious threats to public health. It is likely that solutions to the obesity pandemic will require changes in public policy and that scientific insight into obesity will be invaluable for guiding those changes. Now, a new review of human brain imaging studies published by Cell Press in the journal Trends in Endocrinology and Metabolism suggests that a major reason for the dramatic increase in obesity may be a heightened sensitivity to heavily advertised and easily accessible high-calorie foods. http://medicalxpress.com/news/2012-04-heightened-sensitivity-cheap-high-calorie-food.html Medical research Thu, 05 Apr 2012 12:00:01 EST news252845334 Mount Sinai School of Medicine researchers have discovered that marijuana-like chemicals trigger receptors on human immune cells that can directly inhibit a type of human immunodeficiency virus (HIV) found in late-stage AIDS, according to new findings published online in the journal PLoS ONE. http://medicalxpress.com/news/2012-03-marijuana-like-chemicals-inhibit-human-immunodeficiency.html HIV & AIDS Tue, 20 Mar 2012 17:00:01 EST news251480595 (HealthDay) -- Medications taken by millions of Americans for mood disorders, high blood pressure, diabetes and other chronic conditions can have an unhealthy side effect: weight gain. http://medicalxpress.com/news/2012-03-prescription-meds-unwanted-pounds.html Medications Fri, 02 Mar 2012 11:01:19 EST news249908463 (Medical Xpress) -- Exercise is the key to overcoming the adverse metabolic effects passed on to offspring by their overweight mothers, with research showing for the first time these effects can be almost completely reversed through physical activity. http://medicalxpress.com/news/2012-02-reverse-negative-effects-maternal-obesity.html Health Thu, 09 Feb 2012 08:30:15 EST news247998537 (Medical Xpress) -- New research from Uppsala University shows that a specific brain region linked to appetite regulation is reduced in elderly people who are obese.
