After a 30-year, record-shattering rise, U.S. obesity rates appear to be stabilizing. New statistics cited in two papers report only a slight uptick since 2005 - leaving public health experts tentatively optimistic that they may be gaining some ground in their efforts to slim down the nation. Many obesity specialists say the new data, from the Centers for Disease Control and Prevention, are a sign that efforts to address the obesity problem - such as placing nutritional information on food packaging and revising school lunch menus - are beginning to have an effect in a country where two-thirds of adults and one-third of children and teens are overweight or obese.

To combat a growing problem with anorexia and bulimia, a new law in Israel bans fashion models who are considered unhealthily thin and requires the labeling of photos that are digitally altered to make the models look thinner. Unhealthily thin is defined as a body-mass index lower than 18.5. An example being tossed around is that a woman 5 feet 8 inches tall who weighs 120 pounds would be considered, well, not quite kosher for the cameras. That's a long way from zaftig, but certainly an improvement over the bony waifs that have too long been held up as icons of beauty.

Packing on even a few extra pounds in midlife can increase the risk of developing dementia, such as Alzheimer's disease, by 70% or more, Swedish researchers reported Monday. Earlier studies had shown an increased risk from being obese, but the new research reported in the journal Neurology is the first to show that simply being overweight is enough to increase the risk. "Our results contribute to the growing evidence that controlling body weight or losing weight in middle age could reduce your risk of dementia," co-author Dr. Weili Xu of the Karolinska Institutet in Stockholm said in a statement.

Having childhood attention deficit hyperactivity disorder could lead to a life of obesity, even if ADHD symptoms disappear in adulthood, a new study shows. The study, which followed up on 207 middle-class men who had been diagnosed with ADHD as children, found that some 33 years after their diagnosis, their body mass index was significantly higher than those without ADHD. Their propensity to become obese was twice that of adults who were never diagnosed with ADHD, according to the study published Monday in the journal Pediatrics.

Being obese might up the chance of developing Type 2 diabetes, but the true risk factors may lie in how much overweight someone is and how long they've been that way. Much like figuring how numbers of cigarettes smoked and years of smoking relate to lung cancer risk, researchers set out to see how degree and length of obesity factored into the risk of getting Type 2 diabetes. They looked at data on 8,157 teens and young adults who were 14 to 21 years old at the start of a national study.

As little as one hour of low-intensity exercise a week could reduce the risk of colon polyps among people of various racial and ethnic groups, a study finds. The study, presented recently at the Digestive Disease Week meeting in Chicago, analyzed data on 982 patients who underwent colonoscopies. Polyps were found in 29.5% of the study subjects. Patients who hadn't exercised at least one hour a week had a polyp prevalence of 33.2%, while the prevalence rate among those who did exercise one hour or more was 25.3%.

When a nearly 600-pound man who boldly promoted food at a restaurant called the Heart Attack Grill dies, one of the first reactions is likely to be ... , well, not one of surprise. But then comes the news that Blair River might have died of pneumonia. Hold on. Don't order up that 8,000-calorie burger just yet. Note that there is a potential link between obesity and pneumonia. "After accounting for factors such as lifestyle and education, moderately obese men -- those with a body mass index between 30 and 34.9 -- had a 40% greater risk of pneumonia compared with those of normal weight (BMI of less than 24.9)

About 18% of youths 12 to 19 are obese, as well as 20% of children 6 to 11 and 10% of those 2 to 5 years old. These Centers for Disease Control and Prevention figures date to 2008, but all indications are that those numbers are on the rise. How do you know whether your child is obese? You can't tell just by looking. One of the tools a doctor will use is a BMI growth chart that compares your child's body mass index, or BMI, calculated from his or her weight and height, with others of the same sex and age. Children who fall in the 85th to 95th BMI percentiles (meaning 85% to 95% of children have a lower BMI)

If obesity rates continue to climb in the U.S. as they've done in the past, about half of all men and women could be obese in 20 years, adding an extra 65 million obese adults to the country's population. The figures are from a study released Thursday in the journal the Lancet (part of a four-part obesity series) that used past trends to predict what the future might look like in the U.S. and the U.K. if people keep gaining weight at that rate. It's not a pretty picture--along with expanding waistlines may come higher disease rates and, in turn, greater healthcare costs.

Fat kids often turn into fat adults with a host of related health problems: diabetes, high blood pressure, clogged arteries. But a study finds that if those heavy kids lose weight they may be on a par with people who were never overweight. A meta-analysis released today in the New England Journal of Medicine looked at weight status and health among 6,328 people who were followed from childhood for an average of 23 years. The study subjects were divided into four categories: those who were normal weight as kids and not obese as adults; those who were overweight or obese as kids but not obese as adults; those who were overweight or obese as kids and obese as adults, and those who were normal weight as kids but obese as adults.
