We may be fatter than we think, researchers report
Melissa HealyAs 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.
The researchers suggested that body fat would predict individuals' health risks better than the BMI. To measure fatness, they used a costly diagnostic test called dual-energy X-ray absorptiometry, or DXA, and calculated subjects' level of obesity based on fat-composition standards used by the American Society of Bariatric Physicians.
