Common Sweetener Found In Many Foods Leads To Leptin ResistanceEating too much fructose can induce leptin resistance, a condition that can easily lead to becoming overweight when combined with a high-fat, high-calorie diet, according to a new study with rats. Although previous studies have shown that being leptin resistant can lead to rapid weight gain on a high-fat, high-calorie diet, this is the first study to show that leptin resistance can develop as a result of high fructose consumption.
Health Department Launches Calorie Education Campaign - New York City Department Of Health And Mental Hygiene"Read 'em before you eat 'em," the Health Department advises in a new campaign launched today to help New Yorkers make the most of the city's calorie-posting rules. Under the New York City Health Code, chain restaurants are now required to post calorie counts for food items on menus and menu boards. The rule took effect this summer, after a federal court upheld it and an appellate court refused to delay enforcement while the industry tries again to overturn it.
Waste From Gut Bacteria Helps Host Control Weight, UT Southwestern Researchers ReportA single molecule in the intestinal wall, activated by the waste products from gut bacteria, plays a large role in controlling whether the host animals are lean or fatty, a research team, including scientists from UT Southwestern Medical Center, has found in a mouse study. When activated, the molecule slows the movement of food through the intestine, allowing the animal to absorb more nutrients and thus gain weight. Without this signal, the animals weigh less.
Parents' Perception Of Whether Their Children Are Under Or Overweight: More Than 4 In 10 Are WrongMore than four in 10 parents with underweight and overweight children mistakenly believe their children are in the average weight range, according to University of Melbourne research. The study also finds that different methods of assessing children's weight - such as BMI or waist circumference - result in different rates of children being identified as overweight or underweight. According to BMI, more children were classified as overweight, than compared to waist circumference.
Obese People's Brains Show Less Pleasure From EatingNew research from the US suggests that certain people may have a genetic predisposition to obesity because the reward centres in their brains respond sluggishly after eating, so to get more pleasure from eating they opt for foods denser in calories which makes them gain weight.
Australian Medical Association Backs 'Measure Up' CampaignAMA President, Dr Rosanna Capolingua, commended the government on the launch of its 'measure up' campaign. The campaign, which was launched today, is aimed at helping people understand the health risks posed by carrying excessive weight. "We are pleased to see the government is highlighting this important indicator. It is also vital people understand they need to see a doctor to be advised on not only the cause, but the management of the issue.
Black Patients With Chronic Pain Less Likely To Have Obesity AssessedAt the intersection of two U.S. health epidemics - obesity and chronic pain - researchers from the University of Michigan Health System found black patients with chronic pain were less likely to have their weight or body mass index (BMI) recorded, even though they are at higher risk for having obesity when compared with their white counterparts.
Fighting Obesity, Hypertension, Diabetes And Other Metabolic Diseases By ComputerScientists know that different normal and diseased tissues behave differently. But a method that tells them just how they do so may one day give medical science a new way to fight obesity, hypertension, diabetes and other dangerous disorders of the metabolism. Until now, scientists had to rely on basic observations at the cellular level, since they lacked information about the metabolic processes of individual organs, such as the liver, heart and brain.
Being Fat And Unfit Linked To Inflammation RiskUS scientists found that men who were fat and unfit were more likely to have raised levels of white blood cells, a marker for inflammation in the body that is believed to raise the risk of coronary heart disease and other illnesses.
Glucose Formation By The Liver Altered By Low-Carb DietsA new study shows that a low-carbohydrate diet changes hepatic energy metabolism. When carbohydrates are restricted, the liver relies more on substances like lactate and amino acids to form glucose, instead of glycerol. These findings are in the November issue of Hepatology, a journal published by John Wiley & Sons on behalf of the American Association for the Study of Liver Diseases (AASLD).
