7 weight loss myths (sort of) debunkedThere's a lot said about how to lose weight. As it turns out, a lot of what's said may not be true. To sort fact from fiction, a group of doctors and nutritionists researched the medical evidence behind common claims and presented their findings Wednesday in the New England Journal of Medicine. Beyond academia, however, the doctors and nutritionists also have deep ties to industry, receiving grant support and consulting fees from food, drug, and diet companies, raising questions about how wide a net of inquiry the authors were willing to cast. Still, here are what the researchers say are the seven myths about obesity:

Meal times may affect weight loss successLosing weight may not be just about WHAT you eat but WHEN you eat it, according to a new study. Participants in the study who ate a bigger meal later in the day lost less weight than those who ate earlier. Study authors Marta Garaulet and Dr. Frank Scheer, director of the medical chronobiology program at Brigham and Women’s Hospital in Boston, followed 420 people in Spain during a 20-week weight loss treatment program. The participants were split into two groups – early eaters who ate lunch before 3 p.m. and late eaters who ate lunch after 3 p.m. In Spain, lunch is the biggest meal of the day, comprising about 40% of a person’s daily calories. The early eaters, on average, lost 25% more weight than the late eaters over the course of the study, according to Scheer.

Asthma, eczema and hay fever may be linked to fast foodTeenagers and young children who eat fast food could be increasing their risk of developing asthma, eczema and hay fever, according to a study published Monday in the British Medical Journal's respiratory journal Thorax. The International Study of Asthma and Allergies in Childhood (ISAAC) study used written questionnaires completed by 319,196 13- and 14-year-olds from 51 countries and by the parents of 181,631 6- and 7-year-olds in 31 countries. They were asked if they had symptoms of the three conditions and about their weekly diet - including the types of foods they ate over the last year, and how often.

Obesity among young children declines slightlyThe number of young children who are obese and extremely obese is going down, according to new data released by the Centers for Disease Control and Prevention. In what researchers say is the first national study to show that the prevalence of obesity among young children may have begun to decline, scientists analyzed data from more than 27 million children from low-income families between the ages of 2 and 4 in 30 states and the District of Columbia. "The results of this study indicate modest recent progress of obesity prevention among young children," according to the study published Tuesday in the Journal of the American Medical Association (JAMA).

Cardio burns more fat than weight liftingIf you want to burn fat and lose weight, aerobic exercise may be your best workout option, according to a study in the Journal of Applied Physiology. It was more effective than a weight-lifting routine, and about as beneficial as workouts combining cardio and strength training, researchers found. "If a person is going to give me three hours of exercise a week,the most effective way to lose fat is to spend that time doing aerobic training," says lead study author Leslie Willis, an exercise physiologist at Duke University Medical Center in Durham, North Carolina. If you lift weights, this doesn't mean you should stop, but if your time is limited and your main goal from exercise is to lose weight, cardio may be better than weight training, according to Willis.

Overeating in children may be linked to drug useDo bad nutrition habits like overeating or binge eating lead to smoking pot? Some health experts think they might, according to a study published Monday. Habits like overeating have always been known to affect our health, nutritionists say. In some cases, people say they lose control and just can’t stop. Now scientists are finding that both habits and that feeling of lacking control may lead to other health issues. Researchers at Boston Children’s Hospital studied a group of 16,882 boys and girls between the ages of 9 and 15 who participated in the Growing Up Today Study, beginning in 1996. From that time to 2005, investigators sent out questionnaires every 12 to 24 months, asking if these children were overeating or binge eating. Binge eating was defined as eating an amount of food that is larger than most people would eat in the same time span under similar circumstances and feeling a lack of control over eating during that time. Overeating did not have to be connected to loss of control.

Pesticides in tap water, produce linked to food allergiesPesticides in produce and drinking water may be playing a role in the increasing prevalence of food allergies, according to a new study. Researchers looked at 2,211 people and found those in the top 25% for urine concentrations of chemical dichlorophenols – used to chlorinate tap water and keep pests off produce - were also 80% more likely to have a food allergy. "Adults can develop food allergies even though they're not kids anymore," says allergist and study author Dr. Elina Jerschow. "Adult allergies to foods are on the rise. That certainly includes shellfish and fish allergies, but also peanuts. We don't know what influences this development. But having been exposed to dichlorophenols in our study suggests there could be some link." FULL POST

FDA: Several violations uncovered at Sunland's peanut plantHealth officials have found more clues about the nut product contamination that lead to at least 41 people getting sick this summer. Conditions at the Sunland, Inc. facility in Portales, New Mexico, may have contributed to the contamination of peanut butter and almond butter products with salmonella bredeney, according to new observations posted on the Food and Drug Administration website Thursday. These conditions were observed during inspections of the facility that took place between September 17 and October 16. Federal investigators determined that between June 2009 and August 2012, Sunland cleared - and in some cases distributed - peanut or almond butter products from 11 different lots, even though internal testing showed the presence of the salmonella bacteria.

Diabetes diagnoses increasing at alarming rateThe odds are increasing that you or someone you know has Type 2 diabetes. The latest Morbidity and Mortality report (MMWR) released by the Centers for Disease Control and Prevention shows that from 1995 to 2010, there was at least a 100% increase in the prevalence of diagnosed diabetes cases in 18 states. Forty-two states saw an increase of at least 50%. "Even when you know that [the prevalence of diagnosed diabetes] is increasing, to see that level of increase was shocking to me," says Linda Geiss, a statistician with CDC's Division of Diabetes Translation and the lead author of the MMWR. "It was the 100% figure. 100% – that's a large increase." Predictably, states in the South where obesity levels have also steadily increased had some of the highest increases in diabetes. Oklahoma topped the list with an increase of 226%, followed by Kentucky with 158%, Georgia with 145%, Alabama with 140% and the state of Washington with 135%.

Exercise lengthens your life - even if you're overweightAdd this to the list of reasons why exercise is good for you: A new study says 150 minutes a week of moderate-intensity, leisure time exercise is associated with roughly 3.4 years added to a person's life. Researchers from the National Cancer Institute, Harvard Medical School, and other organizations analyzed six different prospective cohort studies of more than 632,000 people ages 40 and older. The studies had a median follow-up period of 10 years, with roughly 82,000 reported deaths. Regular, moderate intensity exercise was associated with an increased life expectancy, even when the person exercising had an unhealthy Body Mass Index (BMI). Dr. I-Min Lee, a professor of medicine at Harvard Medical School and the senior author of the study, says that not exercising but having a healthy weight was associated with 3.1 fewer years of life, compared to obese people who were active. Conversely, people who exercised 150 minutes a week and had a healthy BMI gained an extra 7.2 years of life. FULL POST |
