"There has never been a higher percentage of overweight Americans, according to the Centers for Disease Control and Prevention. But there has rarely been a lower percentage of Americans who actually believe they are overweight.
The CDC found that 70.4 percent of Americans are overweight or obese. Those levels are determined by a person’s body mass index. A person who is 5 feet, 9 inches would be overweight at 170 pounds, which is a BMI of 25. Obesity is set at a BMI of 30, or 200 pounds for a person who is 5 feet, 9 inches."
