(CNN)  -- Did Jamie Oliver really shape up America's unhealthiest city? A spokeswoman for Huntington, West Virginia -- the city Oliver singled out as one of the unhealthiest places in America -- says local residents are exercising and eating better. But she's not giving much credit to the cheeky British chef and nutrition activist. "What people need to realize is there was already a movement to make Huntington healthier," says Brandi Jacobs-Jones, whose West Virginia hometown plays a starring role in Oliver's new macro-makeover show "Jamie Oliver's Food Revolution," set to debut on ABC on Sunday. Huntington first made its way into the national consciousness in 2008, when The Associated Press named it "America's fattest city," citing unmatched rates of obesity, heart disease and diabetes, and rates of toothlessness among older residents.
