While these mice maintain normal activity and body weight, they do not have the energy to exercise. In the December 1 issue of Cell Metabolism, Dr. Kelly's team reports what happens when muscle tissue lacks PGC-1, a protein coactivator that muscles need to convert fuel into energy. http://phys.org/news210346745.html Medicine & Health Tue, 30 Nov 2010 13:39:23 EST news210346745 A fat yet muscular mouse is helping researchers learn whether more muscle improves the cardiovascular health of obese individuals. http://phys.org/news209648973.html Medicine & Health Mon, 22 Nov 2010 12:50:03 EST news209648973 An analysis of nationally representative data suggests that being obese in adolescence increases the risk of being severely obese in adulthood, with the risk higher in women, and highest for black women, according to a study in the November 10 issue of JAMA. http://phys.org/news208542213.html Medicine & Health Tue, 09 Nov 2010 16:23:47 EST news208542213 Scientists have revealed that an anti-obesity drug changes the way the brain responds to appetising, high-calorie foods in obese individuals. This insight may aid the development of new anti-obesity drugs which reduce the activity in the regions of the brain stimulated by the sight of tasty foods. http://phys.org/news207333176.html Medicine & Health Tue, 26 Oct 2010 17:33:21 EST news207333176 The medical costs of obesity are twice as high as previously reported, according to the first study to estimate the causal effects of obesity on U.S. medical costs. http://phys.org/news206809030.html Medicine & Health Wed, 20 Oct 2010 16:30:01 EST news206809030 An intensive lifestyle intervention program designed to achieve and maintain weight loss improves diabetes control and cardiovascular disease risk factors in overweight and obese individuals with type 2 diabetes, according to four-year results of the Look AHEAD study, funded by the National Institutes of Health and the Centers for Disease Control and Prevention.

Researchers writing in BioMed Central's open access journal BMC Public Health interviewed 142 obese people about their opinions on interventions ranging from gastric bands to legal regulation, finding that non-commercial, non-stigmatizing techniques were preferred. http://phys.org/news198354956.html Medicine & Health Wed, 14 Jul 2010 19:36:11 EST news198354956 Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, finds marked differences between obese and lean men in how they respond to the taste of fat. Fat also is less effective in obese men in stimulating certain gut hormones that are released into the bloodstream and normally suppress appetite. http://phys.org/news198236601.html Medicine & Health Tue, 13 Jul 2010 10:43:33 EST news198236601 Overweight and obese individuals from the Asia-Pacific region are significantly more likely to die from cancer compared with individuals in the normal weight range.

The lower risk of problems associated with fatty liver was not contingent upon weight loss, but a direct result from the increased aerobic exercise. The results of this study are published in the October issue of Hepatology, a journal of the American Association for the Study of Liver Diseases. http://phys.org/news171731410.html Medicine & Health Wed, 09 Sep 2009 16:10:49 EST news171731410 Scientists at the University of Mainz have discovered a close correlation between over-indebtedness and obesity.

Now, a new study in the June Cell Metabolism shows that blood sugar control in those animals can be completely restored by returning leptin sensitivity to a single class of neurons in the brain, which account for only a small fraction of those that normally carry the hormone receptors. http://phys.org/news163164889.html Biology Tue, 02 Jun 2009 12:36:37 EST news163164889 A new study appearing in Clinical Cardiology examines the average fitness level of the morbidly obese (body mass indexes between 40.0 and 49.9). The findings show that the tested population was sedentary for more than 99 percent of the day and, on average, walked less than 2,500 steps per day - far below healthy living guidelines of 10,000 steps per day. The results provide important links between obesity, poor fitness and cardiovascular disease. http://phys.org/news157219241.html Medicine & Health Wed, 25 Mar 2009 17:01:30 EST news157219241
