As if the nation's weight problems were not daunting enough, a new study has found that the body mass index, the 180-year-old formula used to distinguish between healthy and unhealthy weight, may be incorrectly classifying about half of women and just over 20% of men as being the picture of health when their body-fat composition suggests they are obese. The study, published Monday in the journal PLoS One, uses a patient's ratio of fat to lean muscle mass as the "gold standard" for detecting obesity and suggests that it could be a better bellwether of an individual's risk for health problems.

When roasted at 475 degrees, coffee beans are sometimes described as rich and full-bodied. But for the full-bodied person who is not so rich, unroasted coffee beans - green as the day they were picked - may hold the key to cheap and effective weight loss, new research suggests. In a study presented Tuesday at the American Chemical Society's spring national meeting in San Diego, 16 overweight young adults took, by turns, a low dose of green coffee bean extract, a high dose of the supplement, and a placebo.

There has been lots of excitement this week as a horde of scientists released their first looks at the trillions of microbes that live in (or on) our bodies. As well as the two main papers published in Nature, a slate of reports was published in other journals, containing all kinds of tidbits. One week earlier, another slate of “microbiome” papers was published in the journal Science. We already covered the nuts and bolts of the Human Micriobiome Project report.

So your body mass index says you're obese, but you don't have "pre-diabetes" - a mix of factors such as hypertension, high cholesterol and high glucose levels that indicates you're on the road to metabolic illness. And you're thinking you've beaten the odds, right? Wait 10 years, a new study says. Odds are, you'll be proven wrong. New research finds that even when a person is "metabolically healthy," being obese raises his or her risk for cardiovascular disease and premature death.

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.

The federal government is reducing its threshold for defining who is overweight, determining that someone who stands 5-foot-4 and weighs 145 pounds is hefty enough to harm their health. In guidelines to be formally released later this month, a panel of experts convened by the National Institutes of Health concluded that a person with a body mass index as low as 25--5-foot-4, 145 pounds or 5-foot-10, 174 pounds--should be considered overweight.
