A nutrition professor at the University of Rhode Island studying the effects of chewing sugar-free gum on weight management has found that it can help to reduce calorie intake and increase energy expenditure. http://www.physorg.com/news175871180.html Medicine & Health Tue, 27 Oct 2009 14:50:04 EST news175871180 As we all know from experience, people eat not only because they are hungry, but also because the food just simply tastes too good to pass up. Now, a new study in the August 6th Cell Metabolism, a Cell Press publication, helps to explain how leptin, a hormone produced by fat tissue, influences that motivation to eat. http://www.physorg.com/news168696652.html Medicine & Health Wed, 05 Aug 2009 13:11:17 EST news168696652 Researchers at The Scripps Research Institute, the University of California, San Diego, and Ohio State University have used a very sensitive fluorescence technique to find that a bacterial protein thought to exist in one "natural" three-dimensional structure (shape), can actually twist itself into a second form, depending on the protein's chemical environment. One folded form is active and the other is inactive, but the protein can easily morph from one state to another. http://www.physorg.com/news164652632.html Chemistry Fri, 19 Jun 2009 17:50:52 EST news164652632 Insomnia has long been associated with poor health, including weight gain and even obesity.
