If we are bias of women's weight, aren't we taking a step backwards and showing TRUE unattractiveness?

Just as <3 has mentioned, what our society finds beautiful goes in cycles according to whats desirable in the world. For example, back when "thick" was considered beautiful, those who were thick had plenty of food to eat. This was desirable in society because the class system was very air-tight, and there wasnt a lot of food (or money to buy food) going around. So, those that had money were able to buy food, in other words, the top 1% of society. Today, those with money spend it on weightloss programs, surgery, and personal trainers. Thus, they are thin and "beautiful". It all really depends on society and the period it was in. That was kinda hard to put into words, hahah, i hope it made some sense x)
