Burdened with one of the highest adult obesity rates in the US, Oklahoma City went on a citywide diet in 2008, as then-mayor Mick Cornett challenged residents to collectively lose a million pounds.

The campaign involved more than just slogans. In a sprawling city built around cars — where “you literally can get a speeding ticket during rush hour,” as the mayor put it in his 2013 TED talk — Cornett committed to infrastructure-based change. The city built parks, added sidewalks and invested in new running and biking trails, as part of a nearly $800 million tax-funded investment to improve walkability and get residents moving.
