In 2022, new data released by the US Centers for Disease Control and Prevention reveals a concerning trend of increasing obesity rates in a larger number of states. The report shows that 22 states now have at least 35% of adults with obesity, compared to 19 states the previous year. Startlingly, the CDC also notes that a decade ago, none of the states in the US had an adult obesity prevalence reaching or surpassing 35%.

The prevalence of obesity was the lowest among young adults, with approximately 1 in 5 individuals aged 18 to 24 considered obese. In contrast, the rates were approximately twice as high among adults aged 45 to 54, with around 2 in 5 individuals affected, as per CDC data.
