How one of America's most overweight cities lost a million pounds

Oklahoma City has declared war on fat. First the mayor—realizing he had become clinically obese just as his hometown was identified by a magazine as one of America's most overweight cities—challenged his citizens to collectively lose a million pounds. But hitting that target was just the start: This veteran Republican politician then took on the car culture that shaped his nation and asked citizens to back a tax rise to fund a redesign of the state capital around people. This unleashed an incredible range of initiatives, including the creation of parks, sidewalks, bike lanes, and landscaped walking trails across the city. Every school is getting a gym.
