Same thing here. I gained weight moving back as well, due to lack of time and motivation for exercise since I am working without a real break, no walking for anything, and ubiquitous availability of comfort food coupled with high stress due to high cost of living and that work schedule noted above.

I visited Romania a few years ago, and I would say it's a lot more than just that. Fast food was actually a rather rare thing to find outside of any major city, in fact restaurants in general were just not that common. The variety of things at a regular market were far more limited than what you'd find here in the US, however the quality of the food was incredible.
