US News has released statistics that highlight the growing health epidemic in the US.

Around 2 in 5 Americans are obese. Obesity is defined as having a body mass index of 30 or above – according to the Centers for Disease Control and Prevention.

As part of the 2025 Best States rankings, U.S. News evaluated adult obesity rates for all 50 states based on self-reported survey data from the Behavioral Risk Factor Surveillance System, a partnership between the CDC and state health departments. A state’s obesity rate factors into the public health subcategory of the Best States analysis, which provides insight into the quality of life in a state and informs the best states for health care rankings, as well as the list of the best states in the U.S. overall.
