Researchers have uncovered new evidence suggesting factors other than genes could cause obesity, finding that genetically identical cells store widely differing amounts of fat depending on subtle variations in how cells process insulin. http://www.physorg.com/news158943850.html Medicine & Health Tue, 14 Apr 2009 16:06:35 EST news158943850 Where different ethnic groups store fat in their bodies may account for differences in the likelihood they'll develop insulin resistance and non-alcoholic fatty liver disease, researchers at UT Southwestern Medical Center have found. http://www.physorg.com/news157352386.html Medicine & Health Fri, 27 Mar 2009 06:00:48 EST news157352386 High concentrations of blood fats known as triglycerides are common in the United States, according to a report in the March 23 issue of Archives of Internal Medicine. Lifestyle changes are the preferred initial treatment for hypertriglyceridemia (the resulting condition), but physical inactivity, obesity and other modifiable risk factors remain prevalent. http://www.physorg.com/news157045160.html Medicine & Health Mon, 23 Mar 2009 16:40:01 EST news157045160 (PhysOrg.com) -- Researchers at the University of California, Berkeley, have identified a gene that plays a critical regulatory role in the process of converting dietary carbohydrates to fat. In a new study, they disabled this gene in mice, which consequently had lower levels of body fat than their normal counterparts, despite being fed the equivalent of an all-you-can-eat pasta buffet. http://www.physorg.com/news156710717.html Biology Thu, 19 Mar 2009 19:46:06 EST news156710717 Headlines tell us the nation is getting fatter, and that obesity has become an epidemic. But there is more to the story, according to one University of Houston sociologist. http://www.physorg.com/news156449671.html Other Sciences Mon, 16 Mar 2009 19:15:05 EST news156449671 Scientists at the Gladstone Institutes of Cardiovascular Disease (GICD) have found that a key enzyme involved in absorbing fat may also be a key to reducing it. The enzyme, acyl CoA: monoacylglycerol acyltransferase 2 or Mgat2 is found in the intestines and plays an important part in the uptake of dietary fat by catalyzing a critical step in making triglyceride, a kind of fat. Triglyceride accounts for nearly one-third of the fat eaten by people in developed countries. http://www.physorg.com/news156419535.html Medicine & Health Mon, 16 Mar 2009 10:53:09 EST news156419535 Too little vitamin D could be bad for more than your bones; it may also lead to fatter adolescents, researchers say. http://www.physorg.com/news156088325.html Medicine & Health Thu, 12 Mar 2009 14:52:47 EST news156088325 (PhysOrg.com) -- The combination of stress and obesity may significantly influence the development of type 2 diabetes among African-American women, with stress having a potentially greater role, according to researchers from Duke University Medical Center. http://www.physorg.com/news155493632.html Medicine & Health Thu, 05 Mar 2009 16:41:25 EST news155493632 Children who carry a gene strongly associated with obesity could offset its effect by eating a low energy density diet, according to new research from UCL (University College London) and the University of Bristol published today in PLoS ONE. http://www.physorg.com/news155334264.html Medicine & Health Tue, 03 Mar 2009 20:24:51 EST news155334264 A report in the March issue of Cell Metabolism, a Cell Press publication, has found that a signal known to play a role during fasting also switches on early in the fat tissue of obese mice as they progress toward type 2 diabetes. Moreover, treatments that block that "fasting signal" in fat prevent the animals' resistance to insulin, according to the researchers. http://www.physorg.com/news155309238.html Biology Tue, 03 Mar 2009 13:28:17 EST news155309238 Scientists in Germany are reporting development of a new, more effective method to determine whether milk marketed as "organic" is genuine or just ordinary milk mislabeled to hoodwink consumers. Their report appears in the current edition of ACS' Journal of Agricultural and Food Chemistry. http://www.physorg.com/news155189711.html Chemistry Mon, 02 Mar 2009 04:15:37 EST news155189711 It's called the obesity paradox. Although obese people are more apt to suffer from inflammatory diseases, such as diabetes, heart disease, and stroke, they are also more likely to survive a major attack caused by one of those conditions. http://www.physorg.com/news154882304.html Medicine & Health Thu, 26 Feb 2009 14:52:58 EST news154882304 Scientists have determined that a specific gene plays a role in the weight-gain response to a high-fat diet. The finding in an animal study suggests that blocking this gene could one day be a therapeutic strategy to reduce diet-related obesity and associated disorders, such as diabetes and liver damage, in humans. http://www.physorg.com/news154712272.html Medicine & Health Tue, 24 Feb 2009 15:38:17 EST news154712272 A study by researchers at the University of Cincinnati (UC) shows that high-fat diets, even if consumed for a short amount of time, can inflame fat tissue surrounding blood vessels, possibly contributing to cardiovascular disease. http://www.physorg.com/news154190358.html Medicine & Health Wed, 18 Feb 2009 14:40:04 EST news154190358 (PhysOrg.com) -- For the second time in two years, a nationwide outbreak of salmonellosis has been tied to peanut products. This time, over 570 people have been sickened and over 1700 products have been taken off supermarket shelves so far, in what is now the largest food-related recall in the country`s history. http://www.physorg.com/news153597262.html Medicine & Health Wed, 11 Feb 2009 17:55:37 EST news153597262 Hollywood stars of a certain age take note: Research at Berkeley Lab suggests that a protein linked to the spread of several major human cancers may also hold great potential for the elimination of wrinkles and the rejuvenation of the skin. If this promise bears fruit, the protein, called RHAMM, could one day replace injections with neurotoxins that carry such unpleasant side-effects as muscle paralysis and loss of facial expressions. http://www.physorg.com/news153586624.html Medicine & Health Wed, 11 Feb 2009 14:58:07 EST news153586624 Researchers at Georgia State University have found that fat cells give feedback to the brain in order to regulate fat burning much the same way a thermostat regulates temperature inside a house. http://www.physorg.com/news153061813.html Medicine & Health Thu, 05 Feb 2009 13:11:01 EST news153061813 Researchers at UT Southwestern Medical Center have uncovered crucial clues about a paradoxical disease in which patients with no body fat develop many of the health complications usually found in obese people. http://www.physorg.com/news152892574.html Biology Tue, 03 Feb 2009 14:10:00 EST news152892574 Mice whose fat cells were allowed to grow larger than fat cells in normal mice developed "healthy" obesity when fed a high-fat diet, researchers at UT Southwestern Medical Center found in a new study. http://www.physorg.com/news152471533.html Biology Thu, 29 Jan 2009 17:12:51 EST news152471533 If you have trouble keeping weight off and you're wondering why - the surprising answer may well be the cheeseburgers you ate - when you were a toddler. http://www.physorg.com/news151167056.html Medicine & Health Wed, 14 Jan 2009 14:50:56 EST news151167056 Researchers at the University of California, Berkeley, have identified a new enzyme that plays a far more important role than expected in controlling the breakdown of fat. In a new study to be published Jan. 11 in the journal Nature Medicine, researchers report that mice that have had this enzyme disabled remained lean despite eating a high-fat diet and losing a hormone that suppresses appetite. http://www.physorg.com/news150905309.html Medicine & Health Sun, 11 Jan 2009 14:08:29 EST news150905309 Mice exposed to low temperatures develop more blood vessels in their adipose tissue and metabolise body fat more quickly, according to a new study from Karolinska Institutet. Scientists now hope to learn how to control blood vessel development in humans in order to combat obesity and diabetes. http://www.physorg.com/news150543426.html Medicine & Health Wed, 07 Jan 2009 09:37:06 EST news150543426 (PhysOrg.com) -- New research from the University of Maine Department of Psychology has established that that belly fat carried around the middle (central adiposity) is related to decreased cognitive (mental) functioning, with adjustment for multiple cardiovascular risk factors. http://www.physorg.com/news148754196.html Medicine & Health Wed, 17 Dec 2008 16:36:36 EST news148754196 A Kansas State University graduate student has found a correlation between childhood obesity and asthma.
