America continues to get heavier. An analysis of data collected from 2007 to 2012 has found that 71 percent of Americans are obese or overweight. The picture is slightly worse for men, three-fourths of whom are overweight or obese. About 67 percent of women fall into one of those two categories. In all, nearly 35 percent of Americans are overweight, meaning that they have a body mass index between 25 and 29.9. This metric is a generally reliable way of estimating body fat percentage, though it can overestimate fat in athletes and those with a particularly muscular build.
This is because women naturally hold more body fat and men tend to have a larger amount of lean muscle mass. According to Medline Plus, the average woman in America holds about 22 to 25 percent body fat and the average American man holds approximately 17 to 19 percent body fat.eople are considered obese if their body fat exceeds 30 percent for women and is 25 percent or higher for men. Medline Plus recommendations for body fat are 20 to 21 percent for women and 13 to 17 percent for men.
