Based on data compiled by a 2011 obesity survey, 30% of adults are obese. The study asked participants to provide their weight and height to determine whether they were obese. This was the first year that cell phone only households participated in the survey, which allowed the survey to reach a broader spectrum of participants.

Among some of the states with the highest percentage of obese adults were Mississippi, Missouri, Kentucky, Michigan and Alabama. Obesity is an increasing concern across the country, and is a leading contributor to many diseases including diabetes, heart disease and cancer.

The survey results also revealed that, during the past 12 years, the obesity prevalence has increased nationally. For more information about the survey, view the recent government obesity statistics.
