Here's another health risk associated with carrying extra pounds: People who are obese get less protection from the annual flu shot, according to a study released Tuesday. But the authors said that people who are overweight or obese should get a seasonal flu shot anyway. The study involved 461 patients who were vaccinated in 2009 at a clinic in Chapel Hill, N.C. By several measures, the vaccine appeared to wear off faster in people who were overweight or obese than it did in people of healthy weight. For instance, 11 months after getting a flu shot, the level of flu antibodies in the blood had dropped by a factor of four in 25% of the healthy-weight subjects.

Discrimination happens every day, but obese people have little recourse when it happens to them, since there is no federal law protecting this population. But a survey reveals that public opinion may be in favor of anti-discrimination laws--to a point. Researchers from the Rudd Center for Food Policy and Obesity at Yale University surveyed 1,001 adults about their opinions on legal and legislative matters relating to obesity discrimination. They were asked how strongly they agreed or disagreed with statements such as "Obesity should be considered a disability under the Americans with Disability Act so that obese people will be protected from discrimination in the workplace," "The government should play a more active role in protecting overweight people from discrimination," "Overweight people should be subject to the same protections and benefits offered to people with physical disabilities," and "The government should play a more active role in protecting overweight people from discrimination.

Overweight and obese young adults may be known by the company they keep--other overweight and obese people. But if those friends and family members are trying to lose weight, they could be a good influence. How social groups influence our health was the subject of a 2007 New England Journal of Medicine study that found that people who had close friends who were fat might triple their risk of becoming obese as well. A similar connection was found in a study from the June issue of the journal Obesity . But researchers found that connection may also help people lose weight.

Weight-loss surgery has been reserved for people who are morbidly obese, with a body mass index of 40 or greater. However, both gastric bypass surgery and adjustable gastric banding surgery is increasingly performed on less-obese people. That may be a good thing, according to a new study. Researchers at Stanford University looked at the outcomes of 981 people who had gastric bypass surgery. The patient's BMIs ranged from below 35 to greater than 50. The lower-BMI patients had better outcomes than the higher-BMI patients.

Dick Gregory's well-publicized obesity program notwithstanding, Frank Lee, co-founder of Comprehensive Weight Management Inc. in Irvine, said there are too few organized programs dealing with the severely obese. "These people are really in need of help," said Lee, the new firm's chief executive. "We treat people who have tried other programs and failed."

The one-two punch of high-intensity exercise and healthful eating was helpful in getting overweight and obese people to slim down, a study finds. The study, presented this week at the National Obesity Summit in Montreal, Canada, focused on data on 62 overweight and obese men and women involved in a nine-month program at the Montreal Heart Institute . The participants engaged in two to three weekly one-hour supervised exercise sessions and...

It's familiar news by now that America's obesity epidemic is both dangerous and costly. Obesity significantly increases the risk of many diseases, including heart disease and diabetes, and is associated with at least 112,000 deaths a year. The economic impact is equally startling: Obese patients add an estimated $75 billion a year to the nation's medical bill.

When the so-called fat-controlling hormone leptin was first discovered, scientists predicted it would be the basis for a bonanza of new obesity-fighting drugs. That was 15 years ago. Today, scientists are still trying to develop leptin-based weight-loss therapies, but progress has been slower than anticipated. That's because leptin appears to affect several biochemical pathways in the body, and scientists still can't agree on how, precisely, the hormone works. Researchers do, however, know one thing about leptin: "It's way more complicated than we first thought," says Susan Fried, a professor of medicine at Boston University School of Medicine.

Moderately obese people who ate the Mediterranean diet lost more weight than groups of people who followed either a low-fat or a low-carbohydrate diet, researchers reported. The Mediterranean group weighed almost seven pounds less than they weighed six years earlier. In the low-carb group, the total was 3.7 pounds, and the low-fat group was 1.3 pounds. The Mediterranean diet is one based on the eating habits of people who live in that part of the world -- high in produce, and including olive oil and fish.

The ranks of obese Americans are expected to swell even further in the coming years, rising from 36% of the adult population today to 42% by 2030, experts said Monday. Kicking off a government-led conference on the public health ramifications of all those expanding waistlines, the authors of a new report estimated that the cost of treating those additional obese people for diabetes, heart disease and other medical conditions would add up to nearly $550 billion over the next two decades.
