There is a simpler explanation. Fashion, tastes are everything that comes and goes. But natural selection has not gone anywhere :) Men, just like women, when looking for a suitable candidate for procreation, evaluate those properties that they would like to see in their offspring, first of all - health, the main external indicator of which is normal weight , healthy skin color, etc.
Still a very, very long time. I see the following reason: the level of attractiveness is related to the amount of effort required to achieve this beauty. Therefore, in some nations, where there are obvious problems with "eating", completeness is appreciated. In North Korea, ladies love guys with a small tummy. For it is very difficult to get hold of this tummy there, and this speaks of wealth. The same trends are sometimes seen in Africa. In our conditions, where total malnutrition is not an acute problem of the majority, efforts to maintain a woman's figure (physical activity, proper nutrition) are valued. To summarize: thinness will go out of fashion when it is the result of poverty, and not work on oneself. When most of us are severely malnourished. And the unattractiveness of slender women will be the least of the problems. This is my opinion and may be wrong.
I will say, as I think, minus.
Demand creates supply. Men like slender girls who look after themselves. Women want to please men (as well as vice versa, men adjust to the needs of women), so many try to be thin and slender.
But this is an average data, there will always be lovers of anorexic women and vice versa fatties.
And the ideal is not imposed on society in the way in which they want to present it to us. Don't want to be a "victim of society"? Do not be. Do not look after yourself, wear anything. You have every right to do so. But other people have every right to keep communication with you to a minimum.
The obvious answer is that most men are attracted to slender girls. Amendment, not thin and flat, but slender.
Many actresses and celebrities are thin, this also makes you want. Media, television, advertising and more. A woman is dictated to the idea that if she is beautiful and thin, there will be higher demand for you, more male attention, more female envy, you are better - this is the main idea. As it were, a slender body opens the door to other things, brings inner confidence and external attributes.
Now a woman can be forgiven not very distant mind, lack of achievements. But if she is beautiful, most doors will open for her. And the concept of beauty also includes the appearance of the body.
Fashion is different from fashion. Thin people are not in fashion now (only among women themselves), but as public opinion, now it is becoming a trend to be yourself, love your body, engage in pleasure and not chase fashion.
I think that girls want to lose weight because they understand that they are no longer interested in society and especially in the male sex, other girls are losing weight because something happened to them and they somehow trying to lose weight do not think about this or that situation , I think that the fashion for thin people will last forever because it is much more comfortable to live and there will never be any complexes about this and of course there will be no problems what to choose from clothes
