Men also seem to be developing a taste for very thin women. Perhaps trying to start off at a deficit, so that her added-fat doesn't cause her to later be as big as a house.

Women used to just go up a dress size and look a bit plumper.

I always felt so humungous because of my heavy frame.

But I just stayed that way. 

 Our civilization is becoming is more digital and less physical. Whether we like that or not is a different matter. We should at least be open minded to a range of possibilities. And physical excercise is ofc still crucial to live a good life.
