Obesity Obesity (BMI ≥ 30) is a serious problem in the United States and is expected to get worse. Being overweight increases the risk of diabetes, heart disease, and many other ailments, but the severely obese (BMI ≥ 40) are most at risk and the most expensive to treat. The following table shows the percent of obese Americans who are severely obese for selected years from 1990 and projected to 2030.
Percent Obese Who Are Severely Obese
Year | 1990 | 2000 | 2010 | 2015 | 2020 | 2025 | 2030 |
Percent | 6.30 | 9.95 | 15.9 | 18.6 | 21.1 | 23.8 | 26.3 |
