Obesity and Diabetes Rates Increase Dramatically in Survey of States

According to an annual state-by-state survey, adult obesity rates increased in 37 states in the past year ,while Type 2 Diabetes, a weight related disease, increased in 26 states. What's more is that an additional survey showed that whereas not one state in 1991 had an obesity rate at 20%, now every state, except Colorado, has an obese population over 20%.
According to the survey, individuals with a body-mass index of 30 or above, a calculation based on height and weight, are considered obese. For instance, a person who is 5 ft. 8 in. and weighs 200 pounds has a BMI of 30.4.The steady rise in overweight Americans may be attributed to large serving-sizes in restaurants, the high cost of nutritional food, and more time spent in front of TVs and computer screens according to some experts.
So So there's been a study that shows that people who live in neighborhoods where there are more fast food restaurants have higher rates of diabetes and obesity. Is it me or is that a no brainer?And, what's more, this rate increase goes across all racial lines, all ethnic lines, AND all income lines!
