NEW YORK (TheStreet) -- Obesity is a major problem in the U.S. for both our health and our wallets. The Center for Disease Control and Prevention (CDC) reports more than one-third, or 78.6 million, American adults are obese. This problem leads to medical conditions such as heart disease, stroke, type 2 diabetes and certain forms of cancer, all of which are leading causes of preventable death.

Furthermore, obesity weighs down our wallets. The CDC states the estimated annual medical cost of obesity in the U.S. was $147 billion in 2008 U.S. dollars. Obese people also incur $1,429 more in medical costs, on average, than those of normal weight.

One of the primary factors in obesity is the lack of physical activity. After all, it's hard to lose any weight without at least some exercise. And this laziness is more prevalent in some U.S. states than others.

The CDC issued a report entitled "2014 State Indicator Report on Physical Activity," that lists data across multiple fitness categories for adults for each of the 50 states and the District of Columbia. The CDC recorded the percentages of those who reported no leisure-time physical activity, those who met 150-minute-per-week and 300-minute-per-week aerobic activity guidelines, those who met a muscle-strengthening guideline, those who met both the 150-minute and muscle strengthening guidelines, and those who usually walk or bike to work.

Given this data, we can determine which are the 10 laziest U.S. states based on which states reported the greatest lack of leisure-time physical activity. So let's start the countdown and find out which states need to get moving. For good measure, we've included some extra obesity data from 2012 from "F as in Fat," a project of the Trust for America's Health and the Robert Wood Johnson Foundation.

For comparison, here are the national averages for each of the six CDC categories:

No leisure-time physical activity: 25.4%

Met 150-minute-per-week aerobic activity guideline: 51.6%

Met 300-minute-per-week aerobic activity guideline: 31.8%

Met muscle-strengthening guideline: 29.3%

Met 150-minute aerobic activity and muscle-strengthening guidelines: 20.6%

Usually walked or biked to work: 3.4%

10th Laziest: Missouri

The Show-Me State has the 17th-highest adult obesity rate in the country at 29.6%, including 13.5% of children ages 10 to 17.

No leisure-time physical activity: 28.4%

Met 150-minute-per-week aerobic activity guideline: 49.5%

Met 300-minute-per-week aerobic activity guideline: 30.5%

Met muscle-strengthening guideline: 24.7%

Met 150-minute aerobic activity and muscle-strengthening guidelines: 17.3%

Usually walked or biked to work: 2.2%
