I haven't really paid attention to men's physiques, but there's a stark difference between the silhouettes of women in many cities of Europe and those in even the most "superficial" US states such as California. I know the PC police will eat me for lunch for saying this, but the dating pool, at least in the 20s and 30s range, shrinks considerably in the US for anybody used to European body image standards. Whatever's…
Here's a Vox review/summary of a book: http://www.vox.com/2015/7/30/9070255/dorito-effect
> Flavor technology got very powerful in the early 1960s, and it wasn't long after that that we began to see the startling increases in body mass index.
> All the good stuff we grow — tomatoes, strawberries, lettuce — has gotten continually more bland. This has been measured. They have become diluted of nutrients, as well. As we selected crops for agronomic traits like yield, shelf life and disease resistant, we never selected for flavor. And we lost flavor as a result. It's reverse evolutionary pressure.
