The Sirt1 enzyme in the body has generated enormous attention as a possible secret to living longer. Some scientists believe that fasting and drinking wine appear to aid in this quest because both likely activate Sirt1, unleashing its power. http://www.physorg.com/news180087465.html Medicine & Health Tue, 15 Dec 2009 08:40:03 EST news180087465 Getting the correct balance of proteins in our diet may be more important for healthy ageing than reducing calories, new research funded by the Wellcome Trust and Research into Ageing suggests. http://www.physorg.com/news178984012.html Medicine & Health Wed, 02 Dec 2009 14:40:02 EST news178984012 If you feel like you're in a losing battle with a triple-chocolate cake, a "mental budget" can help, according to a new study in the Journal of Consumer Research. http://www.physorg.com/news177701774.html Other Sciences Tue, 17 Nov 2009 18:00:01 EST news177701774 Most weight-control strategies emphasize energy-restricted diets and increased physical activity - and most are not effective over the long term. In a study of a "weight-acceptance" intervention, published in the November 2009 issue of the Journal of the American Dietetic Association, researchers found that there could be long-term beneficial effects on certain eating behaviors using a weight- acceptance intervention approach. http://www.physorg.com/news176565147.html Medicine & Health Wed, 04 Nov 2009 14:10:02 EST news176565147 Enrolling in a weight loss program with a family member or friend appears to enhance weight loss among African Americans, but only if the involved partner attends sessions frequently or also loses weight, according to a report in the October 26 issue of Archives of Internal Medicine. http://www.physorg.com/news175795574.html Medicine & Health Mon, 26 Oct 2009 18:10:01 EST news175795574 A naturally produced molecule called resveratrol, found in the skin of red grapes, has been shown to lower insulin levels in mice when injected directly into the brain, even when the animals ate a high-fat diet. http://www.physorg.com/news174804190.html Medicine & Health Thu, 15 Oct 2009 05:43:55 EST news174804190 A difference in brain activity patterns may explain why some people are able to maintain a significant weight loss while others regain the weight, according to a new study by researchers with The Miriam Hospital. http://www.physorg.com/news172229784.html Medicine & Health Tue, 15 Sep 2009 10:50:01 EST news172229784 A team of scientists from the California Institute of Technology have pinpointed two groups of neurons in fruit fly brains that have the ability to sense and manipulate the fly's fat stores in much the same way as do neurons in the mammalian brain. The existence of this sort of control over fat deposition and metabolic rates makes the flies a potentially useful model for the study of human obesity, the researchers note. http://www.physorg.com/news169818724.html Medicine & Health Tue, 18 Aug 2009 12:52:58 EST news169818724 A gut hormone first described in 1928 plays an unanticipated and important role in the remote control of blood sugar production in the liver, according to a report in the August 6th Cell Metabolism, a Cell Press publication. What's more, the researchers show that rats fed a high-fat diet for a few days become resistant to the glucose-lowering hormone known as cholecystokinin (CCK). http://www.physorg.com/news168697036.html Medicine & Health Wed, 05 Aug 2009 13:30:01 EST news168697036 Overconsumption of fatty, sugary foods leads to changes in brain receptors, according to new animal research at Johns Hopkins University School of Medicine. The new research results are being presented at the 2009 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. The results have implications for understanding bulimia and other binge eating disorders. http://www.physorg.com/news167936267.html Medicine & Health Tue, 28 Jul 2009 01:30:01 EST news167936267 Researchers at Imperial College London have identified a new appetite suppressant for promoting weight loss that they say works in rodents and may one day be used to develop an effective anti-obesity treatment. http://www.physorg.com/news163850449.html Medicine & Health Wed, 10 Jun 2009 11:50:01 EST news163850449 (PhysOrg.com) -- In a study of 130 overweight adolescents, researchers at the University of California, San Diego School of Medicine found that frequent self-weighing is associated with positive behaviors and may prove to be a useful weight-control tool. http://www.physorg.com/news161534783.html Medicine & Health Thu, 14 May 2009 15:47:20 EST news161534783 New research that uses an innovative approach to study, for the first time, the relative contributions of food and exercise habits to the development of the obesity epidemic has concluded that the rise in obesity in the United States since the 1970s was virtually all due to increased energy intake. http://www.physorg.com/news160983988.html Medicine & Health Fri, 08 May 2009 06:47:01 EST news160983988 The secret of staying thin could be at least partly down to a good night's rest, an international conference on obesity heard in Amsterdam on Thursday. http://www.physorg.com/news160924522.html Medicine & Health Thu, 07 May 2009 14:15:41 EST news160924522 Sharing a meal in good company can stimulate the appetite - particularly among hospitalized seniors - according to a new Université de Montréalstudy published in The Gerontologist. http://www.physorg.com/news160753128.html Medicine & Health Tue, 05 May 2009 14:39:12 EST news160753128 The journal Biochemical and Biophysical Research Communications (BBRC), published by Elsevier, will publish an important review this week online, by M.

As older adults tend to reduce their food intake as they age, there is concern that deficits in these micronutrients lead to medical problems. In a study published in the March 2009 issue of the Journal of the American Dietetic Association, researchers examined how well different ethnic groups met the recommended daily allowances (RDAs) through food intake and supplement consumption. The study determined that many middle-aged and older Americans are not getting adequate nutrition. http://www.physorg.com/news155132289.html Medicine & Health Sun, 01 Mar 2009 12:18:42 EST news155132289 Heart-healthy diets that reduce calorie intake -regardless of differing proportions of fat, protein, or carbohydrate -can help overweight and obese adults achieve and maintain weight loss, according to a study funded by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health, and published Feb., 26, 2009, in the New England Journal of Medicine. http://www.physorg.com/news154805509.html Medicine & Health Wed, 25 Feb 2009 17:35:26 EST news154805509 Researchers at Albert Einstein College of Medicine of Yeshiva University have found that overactivity of a brain enzyme may play a role in preventing weight gain and obesity.
