Secondly, you're adectdote doesn't make the "she eats too much" BS. Yes, there are people that may genetically prone to being overwiegh as well as few medical disorders. Even with the a genetic disposition and/or medical condition, there are treatments available to rectify it. But in America as of late, the VAST majority of overwieght people are overwieght becuase of their diet as well as a lack of physical activity.
The last time fat woman were attractive, it was because that was an occasion of wealth. Could afford to eat.
Lastly, I'm personally not fond of what the modern view of "skinny" is. They look like a 2 X 6 with arms and legs! At the same time, don't dig fat girls either. Just not my flavor, some guys do though. I like a little bit of meat on a woman and the pinups of the 50s were what I'd consider to be an ideal figure. However, the anchor in OP would be still consdiered fat or obsese, even in the 50s. There is a big difference, even in the modern standard, by someone who's is a little overwieght and someone who's obses. The anchor is obses, bottom line.
