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.

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.

Sometime later this year, the Centers for Disease Control and Prevention will release its latest accounting of the nation's weight problem, as measured by the body mass index, or BMI. This much we know already: It won't be a pretty picture. The last census reckoned that a third of American adults were overweight, meaning their BMIs (calculated by dividing a person's weight by his height, squared) lay between 25 and 30. About another third weighed in with BMIs over 30 -- the demarcation line that brands them as obese.

When the National School Lunch Program began in 1946, the idea was to get nutritious food into the stomachs of malnourished children from low-income families. Ironic, then, that these days the school lunch program is being scrutinized for its role in contributing to the growing problem of childhood obesity in America. The latest report was published online this week by the Archives of Pediatric and Adolescent Medicine. It concludes that girls who participate in the National School Lunch Program gain weight at a faster clip than other girls from low-income families who do not get the subsidized lunches (and sometimes breakfasts)

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.
