But it's also the source of confusion and worry for many people trying to lose weight. At the same time, calories -- too few or too many -- are causing health problems resulting from malnutrition and obesity that affect billions of people around the world. http://medicalxpress.com/news/2012-04-calories-food-politics.html Health Tue, 24 Apr 2012 05:32:31 EST news254464340 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 Calorie intake from white potatoes is surprisingly modest for adults and school-aged children, according to a new study released today at the Experimental Biology 2012 Annual Meeting. http://medicalxpress.com/news/2012-04-potato-consumption.html Other Sat, 21 Apr 2012 02:59:08 EST news254195905 In order for the nation to achieve goals set by the federal government for reducing obesity rates by 2020, children in the United States would need to eliminate an average of 64 excess calories per day, researchers calculated in a study published today in the American Journal of Preventive Medicine. This reduction could be achieved by decreasing calorie intake, increasing physical activity, or both. Without this reduction, the authors predict that the average U.S. youth would be nearly four pounds heavier than a child or teen of the same age was in 2007-2008, and more than 20% of young people would be obese, up from 16.9% today. http://medicalxpress.com/news/2012-04-calories-childhood-obesity-goals.html Health Tue, 10 Apr 2012 00:00:06 EST news253207993 An excessive intake of cured meats, such as salami, chorizo and bacon, can increase readmission to hospital for people with chronic obstructive pulmonary disease (COPD), according to a study by Spanish researchers from the Centre for Research in Environmental Epidemiology (CREAL) in Barcelona. http://medicalxpress.com/news/2012-03-excessive-meat-consumption-hospital-readmissions.html Diseases, Conditions, Syndromes Thu, 08 Mar 2012 04:00:01 EST news250400928 In the war to lose weight it may be something other than willpower or junk food that's preventing victory: it could be faulty use of mathematics. http://medicalxpress.com/news/2012-02-obesity-mathematical.html Health Thu, 23 Feb 2012 09:30:01 EST news249210399 (Medical Xpress) -- Overweight or obese people with type 2 diabetes are more likely to reduce weight if they focus on cutting back on total calorie intake, rather than specific high protein/high carbohydrate diets according to a new study from the University of Otago, Wellington. http://medicalxpress.com/news/2012-02-calories-protein-carbs-key-weight.html Diabetes Tue, 07 Feb 2012 05:37:35 EST news247815436 Going out to eat has become a major part of our culture.

According to a study conducted at the University of North Carolina at Chapel Hill and published in the August 2011 issue of the Journal of the American Dietetic Association, eating location and food source significantly impact daily energy intake for children. Foods prepared away from home, including fast food eaten at home and store-prepared food eaten away from home, are fueling the increase in total calorie intake. http://medicalxpress.com/news/2011-07-children-frequently-home.html Health Mon, 25 Jul 2011 02:42:21 EST news230780519
