Each year, the Trust for America's Health conducts the F as in Fat study using the CDC's data, which ranks individuals with a body mass index of 30 or higher as obese. BMI is calculated based on weight and height ratios.
This year, Mississippi ranked first, with a 34.9 percent rate of adult obesity. Colorado ranked last, with 20.7 percent. Although that put this state at the bottom, its rate has still increased from last year, when it was 19.8 percent.
According to the CDC, its methods for collecting data have been updated to include cell phones, when in the past only landlines were used. This makes it difficult to directly compare the new study with the past ones, but the evidence still shows that obesity is on the rise.
Although Colorado is staying at the bottom of the obesity list, our rate has almost doubled from 10.7 percent in 1995.
The 2011 F as in Fat report shows that in 1995, Mississippi had the highest obesity rate at 19.4 percent, which was lower than this year's lowest rate: Colorado at 20.7 percent.
The rise in obesity closely correlates with a rise in related diseases, such as diabetes. The states with the largest rise in obesity between 1995 and 2010 -- Oklahoma and Alabama -- also had the largest rise in diabetes.
Childhood obesity poses a big concern, too. In 2011, Colorado ranked 29th, with a rate of 14.2 percent.
This year's study also shows that obesity hasn't decreased in any state. If obesity in Colorado has risen by 10 percent in seventeen years, will we be at 30.7 percent in 2029?
