I just took a vacation in Iowa, the land of my birth. Although I am right at a BMI value of 30, the official boundary between being overweight and being obese (shame on me!), I flattered myself that I appeared relatively fit compared with many Iowans my age. According to a 2010 study by the Centers for Disease Control, more than 28% percent of Iowa adults are obese. In my age bracket, I would guess that the obesity rate is pushing 40%.
Colorado has the lowest adult obesity rate of all the states, a mere 21%. (In relative terms, this is something to boast about. In absolute terms, this is dreadful. In 1992, Colorado's obesity rate was below 10%.)
For the sake of motivation, it's probably better to be an embarrassed fat man in Colorado than a complacent fat man in Iowa.
