I've heard from older family members how in the 1950s (and maybe onward a bit) women were somewhat expected to be on the heavy side. It showed you were wealthy enough to afford more food than average households. In the 1960s, Twiggy was a major fashion icon, and many girls wanted to look like her (my mother was a preteen/teenager at the time, and was obsessed with Twiggy herself). People, historically, have wanted to be like celebrities they like, even in body image. Things like larger breasts and butts, for women now, are the "in" thing to have - when I was younger, that wasn't much of a thing at all - in fact, girls wanted a smaller butt (I had friends ask me, seriously, if the jeans they were wearing made their butt look big, negatively).
Ideal body types have changed time and time again, for men and women. That's why both genders wore corsets in the 19th century - a cinched waist was beautiful to people at the time. Men wore then to appear slightly slimmer with a larger chest, while women wore them very tightly. They even wore them several months into their pregnancy at the time. Look at historical paintings, clothes, or even how ideal body types are across the world now. In Asia, being heavy is seen as a major negative aspect, and super thin girls are seen as highly attractive - and even then, the eastern Asia idea of what makes a person "heavy" varies from the way the western world sees it.
So, yeah. It has changed. And, no one's saying the standard doesn't come from women judging other women, as well.
