(WTNH) – New research has revealed national obesity rates are at an all-time high. And that new study lists country’s fattest and thinnest cities. According to Gallup and Healthways, more than 15% of adults are obese in all but one of the 189 cities surveyed. And last year national obesity rates rose to the highest on record since the annual surveys began in 2008. GMCT’s Ali Reed and Teresa Dufour look at the lists, one of which does contain a Connecticut city.
