Obesity has been on the rise over the past decade across the US, despite the advent of Instagram, "athleisure" and boutique fitness classes. According to data from the CDCP, obesity has risen "significantly" in the past decade, with more than one in three American adults now qualifying as obese.

Another study from ConsumerProtect cited by MarketWatch looks at this trend in greater detail, breaking down the most and least, obese states in the country.

So, which state has the worst obesity problem? that would be West Virginia, where 38.1% of adults are obese. WVa. also has the highest diabetes rate in the country, and ranks poorly on other health metrics that often accompany obesity.
