Activating an enzyme known to play a role in the anti-aging benefits of calorie restriction delays the loss of brain cells and preserves cognitive function in mice, according to a study published in the May 22 issue of The Journal of Neuroscience. The findings could one day guide researchers to discover drug alternatives that slow the progress of age-associated impairments in the brain. http://medicalxpress.com/news/2013-05-caloric-intake-nerve-cell-loss.html Neuroscience Tue, 21 May 2013 17:00:09 EST news288374042 Intermittent fasting is all the rage, but scientific evidence showing how such regimes affect human health is not always clear cut. Now a scientific review in the British Journal of Diabetes and Vascular Disease suggests that fasting diets may help those with diabetes and cardiovascular disease, alongside established weight loss claims. http://medicalxpress.com/news/2013-04-forthcoming-explores-intermittent-fasting-diabetes.html Diabetes Fri, 26 Apr 2013 11:44:59 EST news286195493 (HealthDay)—Continuing education that includes didactic and hands-on cooking sessions improves physicians' self-reported nutrition-related behaviors, according to a research letter published online Feb. 18 in JAMA Internal Medicine. http://medicalxpress.com/news/2013-02-hands-on-cooking-aids-docs-nutrition.html Health Fri, 22 Feb 2013 16:40:01 EST news280765871 (HealthDay)—Finally, some good news in the war on childhood obesity: Kids in the United States now consume fewer calories each day than they did 12 years ago, according to a new government report. http://medicalxpress.com/news/2013-02-kids-consuming-calories.html Health Thu, 21 Feb 2013 13:40:01 EST news280673816 Addressing the obesity epidemic by preventing excess calorie consumption with government regulation of portion sizes is justifiable and could be an effective measure to help prevent obesity-related health problems and deaths, according to a Viewpoint in the September 19 issue of JAMA, and theme issue on obesity. http://medicalxpress.com/news/2012-09-important-role-obesity-epidemic.html Overweight and Obesity Tue, 18 Sep 2012 11:08:33 EST news267185305 (HealthDay) -- The hormonal fluctuations associated with women's menstrual cycles could color their shopping habits, research suggests. http://medicalxpress.com/news/2012-07-menstrual-affect-women-patterns.html Psychology & Psychiatry Tue, 31 Jul 2012 18:20:01 EST news262974822 (HealthDay) -- Intranasally administered insulin is associated with higher brain energy levels and reduced calorie intake, according to a study published online May 14 in Diabetes. http://medicalxpress.com/news/2012-06-intranasal-insulin-linked-food-intake.html Diabetes Thu, 07 Jun 2012 16:28:02 EST news258305273 The international obesity epidemic is widespread, nondiscriminatory, and deadly. But do we really understand all of the factors underlying this alarming trend? The concept of energy balance (energy consumed = energy expended + energy stored) is undeniable, being driven by the first law of thermodynamics. Consequently, there is no contradiction that excessive calorie intake and plummeting levels of physical activity are largely to blame for our ever-expanding waistlines. However, scientists remain baffled as to why some individuals are particularly prone to becoming obese and if there is anything aside from lowering calorie consumption and increasing activity levels that can be done to prevent and/or reverse excessive weight gain in our most at-risk populations. http://medicalxpress.com/news/2012-04-gut-clue-obesity.html Medical research Mon, 23 Apr 2012 15:50:01 EST news254397553 If you don't get enough sleep, you may also eat too much — and thus be more likely to become obese. http://medicalxpress.com/news/2012-03-lack-calorie-consumption.html Health Wed, 14 Mar 2012 16:00:01 EST news250954010 A Yale University-led research team has discovered how reduced expression of a particular gene protects against obesity and type 2 diabetes, possibly prolonging lifespan by mimicking the effects of calorie restriction.
