What Is the Ideal BMI in the United States?
Less than half of American adults have an ideal BMI; this is equivalent to about 68 million adults. About 37 million women between the ages of 20 and 74 have an ideal BMI, while about 31 million men between the ages of 20 and 74 have an ideal BMI.
Approximately 130 million American adults are overweight (defined as having a body mass index equal to or greater than 25). Nearly 61 million adults are obese (defined as a BMI greater than or equal to 30). Even more concerning is that approximately 15 percent of children and adolescents are overweight, and another 15 percent are at risk for being overweight (BMI-for-age between the 85th and 95th percentile).
