Obesity-Related Enzyme Targeted in Mouse Study

Posted 10 days ago by Drugs.com

WEDNESDAY, April 9, 2014 – An enzyme in the fat and liver of mice could take a key role in future attempts to battle obesity and type 2 diabetes, according to a new study. The enzyme – nicotinamide N-methyltransferase, or NNMT – appears to help regulate the ability of cells to burn energy efficiently, researchers report. By hampering the gene that produces the enzyme, researchers were able to keep mice fed a high-fat diet from gaining weight. The mice also became better at using insulin to process blood sugar, which could lower their odds for developing diabetes. "The mice were eating normally. It wasn't a food intake effect. They actually had increased energy expenditure," said senior author Dr. Barbara Kahn, vice chair of medicine at Beth Israel Deaconess Medical Center and a professor at Harvard Medical School. "For every calorie they ate, they burned up more energy." Controlling ... Read more

Obesity May Shorten Colon Cancer Survival

Posted 10 days ago by Drugs.com

WEDNESDAY, April 9, 2014 – Colon cancer patients who were obese before their diagnosis may have an increased risk of dying from their cancer and other causes, a new study finds. "Our data provide further evidence that maintaining a healthy body weight throughout life is very important," said study author Peter Campbell, director of the tumor repository in the American Cancer Society's epidemiology research program. "They also suggest that prediagnosis BMI may be something that clinicians should consider when managing patient care." BMI, or body mass index, is a measurement of body fat based on height and weight. A BMI of 30 or more is considered obese. The study included more than 6,700 colon cancer patients whose BMI two years before diagnosis was calculated based on self-reports. The patients were followed for an average of just over five years. A higher BMI before diagnosis was ... Read more

More U.S. Children Severely Obese, Study Says

Posted 12 days ago by Drugs.com

MONDAY, April 7, 2014 – Contrary to a recent report with encouraging figures on childhood obesity in the United States, a new study presents a more sobering picture of the nation's pediatric weight problem. Severe obesity, which sets kids up for a lifetime of health problems, has increased over the past 14 years, North Carolina researchers found. They used the same data that researchers from the U.S. Centers for Disease Control and Prevention mined for their encouraging report in February. "We found that the number of extremely obese kids seems to be increasing," said lead researcher Asheley Cockrell Skinner, an assistant professor of pediatrics at the University of North Carolina. "This is particularly true for school-age girls and teenage boys." Severely obese children are the ones most likely to have type 2 diabetes as teens and other problems such as heart disease later in life. ... Read more

Childhood Obesity Adds Nearly $20K to Lifetime Medical Costs: Study

Posted 12 days ago by Drugs.com

MONDAY, April 7, 2014 – Over a lifetime, direct medical costs for an obese 10-year-old will be nearly $20,000 higher than those of slimmer peers, according to new research. That translates to a whopping $14 billion in additional direct U.S. medical costs over a lifetime for today's obese 10-year-olds, according to the study. And, those costs only include direct medical costs, such as medications or medical procedures related to obesity. They don't include indirect costs, such as lost productivity and quality-of-life issues, the researchers said. "Our findings show that the estimated direct medical costs incurred by the obese 10-year-old over his lifetime will be roughly $19,000 higher than that of a child who is normal weight, assuming that both children remain in their respective weight categories," said Wan Chen Kang Graham, a study co-author.

Could Dads' Obesity Raise Autism Risk for Kids?

Posted 12 days ago by Drugs.com

MONDAY, April 7, 2014 – Children born to obese fathers, but not obese mothers, may have a slightly higher risk of autism than kids with thinner dads, a large new study suggests. Researchers found that of nearly 93,000 Norwegian children they followed, those born to obese dads had double the risk of developing autism. But the odds were still small: just under 0.3 percent were diagnosed with autism, versus 0.14 percent of kids with normal-weight fathers. The findings, published online April 7 in Pediatrics, are the first to link fathers' obesity to autism risk. And experts stressed that it's not clear whether dads' extra pounds, per se, cause the increase. One possibility is that there's an "indirect" association, said lead researcher Dr. Pal Suren, of the Norwegian Institute of Public Health in Oslo. Certain gene variations, for example, could be linked to heightened risks of both ... Read more

How You Digest Carbs May Influence Weight Gain, Study Says

Posted 16 days ago by Drugs.com

THURSDAY, April 3, 2014 – The way your body digests carbohydrates may affect your risk for obesity, a new genetic study indicates. Researchers focused on a gene called AMY1, which is responsible for an enzyme in the saliva called salivary amylase. When food enters the mouth, the enzyme begins the process of starch absorption that continues in the digestive system. Starches are a type of carbohydrate. People typically have two copies of AMY1, but the number of copies can vary widely. It's believed that higher numbers of the gene evolved in response to diets that contained greater levels of starch, the researchers said. They studied the number of copies of AMY1 in thousands of people from France, Singapore, Sweden and the United Kingdom, and found those with a low number of copies were more likely to be obese. People with fewer than four copies of the gene were about eight times more ... Read more

The Morning Light May Help You Stay Slim

Posted 17 days ago by Drugs.com

WEDNESDAY, April 2, 2014 – Spending time in the bright morning light may help you slim down, new research suggests. The small study found that people exposed to more light earlier, rather than later, in the day tended to be leaner than their peers. "We were very interested in looking at the relationship between lighting and how that may be affecting your weight," explained study senior author Dr. Phyllis Zee, director of the sleep disorders center at Northwestern University Feinberg School of Medicine in Chicago. "This is an early study, but we did indeed see a fairly robust association between the amount of light and the timing of light, and weight," noted Zee. However, she was quick to point out that the study only found an association between early light exposure and lower weight, not a cause-and-effect link. The study included 54 adults. Twenty-six were male, and the average age ... Read more

Overweight Teens Don't Share in Life-Expectancy Gains: Study

Posted 28 Mar 2014 by Drugs.com

FRIDAY, March 28, 2014 – Gains in life expectancy don't extend to adults who were overweight or obese as teens, according to a new study. The average lifespan in the United States has increased by more than a decade since 1950, to nearly 79 years for someone born in 2011, the researchers said. But rising obesity rates may stall that progress, they said. "In studying the rate of death among adults younger than age 50, we found that there was no improvement among men who were overweight or obese as teenagers," said Dr. Amir Tirosh, of the division of endocrinology at Brigham and Women's Hospital in Boston. "The mortality rate among overweight and obese teenagers in the years 2000 to 2010 was as high as the rate observed in the 1960s and 1970s," he said. The researchers analyzed long-term data from more than 2.1 million people in Israel who were born between 1950 and 1993 and evaluated ... Read more

'Grazing' Appears No Better for Weight Loss Than Standard Meals

Posted 27 Mar 2014 by Drugs.com

THURSDAY, March 27, 2014 – For weight loss, some swear by "grazing" – eating several small meals throughout the day – instead of eating fewer meals at more traditional mealtimes. Now, a small study comparing both approaches finds it doesn't matter which tactic you use, as long as you reduce total calories. Women who ate five meals on one test day and two regular meals on another (consuming the same total calories each day) burned the same amount of calories both days, researchers found. Despite folklore that grazing somehow revs up your metabolism, it doesn't appear to be the case, said study researcher Dr. Milan Kumar Piya. "If you eat two meals or five, as long as it's the same number of calories; there is no difference in energy expenditures, so there is no effect on weight loss," said Piya, a clinical lecturer with the U.K. National Institute for Health Research, at University ...

Salt's Harm Evident in Heavy Teens, Study Finds

Posted 20 Mar 2014 by Drugs.com

THURSDAY, March 20, 2014 – Teens aren't immune to the ill effects of salt: A new study suggests that eating too much salty food might speed cellular aging in overweight and obese teenagers. Researchers divided nearly 800 teens, aged 14 to 18, into two groups based on their salt intake. Those in the high-intake group consumed an average of more than 4,100 milligrams (mg) of salt a day, while those in the low-intake group consumed an average of less than 2,400 mg a day. Both groups consumed far more salt than the 1,500 mg per day maximum (about two-thirds of a teaspoon) recommended by the American Heart Association. "Even in these relatively healthy young people, we can already see the effect of high [salt] intake, suggesting that high [salt] intake and obesity may act synergistically to accelerate cellular aging," said lead author Dr. Haidong Zhu, an assistant professor of pediatrics at ...

Rigid Parenting Style Linked to Obese Kids

Posted 19 Mar 2014 by Drugs.com

WEDNESDAY, March 19, 2014 – Kids with demanding parents who are rigid about rules, stingy with affection and won't discuss limits are far more likely to be obese than children whose parents practice a more balanced parenting style, new research suggests. Canadian scientists found that obesity rates were about one-third higher in children up to age 11 whose parents used a so-called "authoritarian" parenting style, marked by inflexibility over rules and a lack of emotional responsiveness. In a group of more than 37,000 children, these kids were significantly heavier compared to those whose "authoritative" parents were generally affectionate, willing to discuss behavior limits and set healthy boundaries. "These findings are consistent with what's been found for other dimensions of children's health – that an authoritative parenting style [compared to an "authoritarian" approach] is the ... Read more

Genes May Influence Weight Gain From Fried Foods: Study

Posted 19 Mar 2014 by Drugs.com

WEDNESDAY, March 19, 2014 – Genetics help determine whether a frequent diet of fried food will make you fat, according to a new Harvard study. Eating fried food more than four times a week had twice as big an effect on body size for people at high genetic risk of obesity compared with people at low risk, researchers found after analyzing data from three U.S. trials. Moreover, the more pro-obesity genes you carry, the bigger you'll get chowing down on fried chicken and such, the researcher said. Such findings help explain why Americans' overall bad health habits don't affect everyone equally, said Claude Bouchard, chairman of genetics and nutrition at the Human Genomics Laboratory of Pennington Biomedical Research Center, in Baton Rouge, La. "Our dietary habits and our lack of physical activity is driving the obesity epidemic, but the force of the behavioral driver is not the same in ... Read more

Weight-Loss Surgery Might Help Mild Knee Pain

Posted 18 Mar 2014 by Drugs.com

TUESDAY, March 18, 2014 – Weight-loss surgery reduces knee pain in obese people, and the results are similar to those seen in patients who have a knee replacement, according to a small new study. The study included 20 obese patients who had weight-loss surgery and 40 patients who had total knee replacement due to arthritis. One year after their procedure, the patients who had weight-loss surgery reported significant improvements in knee pain. Their results were comparable to the patients who had a knee replacement, according to the study, which was presented Friday at the annual meeting of the American Academy of Orthopaedic Surgeons, in New Orleans. Compared to the knee-replacement patients, the weight-loss patients showed much greater improvement in knee function six months after surgery, according to an academy news release. After one year, however, the difference was much smaller. ... Read more
