I lived in Europe for multiple years and then moved to the US. I gained a lot of weight. This had to do with both less of an effective culture of walking and public transit in the city I lived in the US. And also the quality and availability of relatively healthy, tasty foods at a reasonable price. I’ve also had the same experience on shorter (few month) stays in Europe, while still working a 9-5.
