Your house is making you gain weight. This U.S. city was designed precisely to prove it

Oklahoma City was once among the most obese cities in the United States, prompting Mayor Mick Cornett to lead a campaign to cut collective weight.

The case showed that the problem was not only diet or lack of exercise, but also the built environment: neighborhoods without sidewalks and car-oriented intersections.

Long distances between homes, shops, and services can reduce everyday walking and increase obesity risk.

The story underscores that public health depends not just on personal habits, but on how streets, neighborhoods, and infrastructure are designed.
