Why the BMI May Be a Flawed Measure of Health

The body mass index, or BMI, may not be an accurate indicator of a person's risk of heart disease or diabetes, according to a new study. The results suggest that about 75 million adults in the United States may be misclassified — they have a true risk of heart disease or diabetes that is either lower or higher than suggested by their BMIs, the researchers said. The new results show that BMI is a flawed measure of health, they said.
