This is a meme that has been popping up among bloggers and commenters who read the blog formerly known as Roissy in DC. It’s that women today are all obese, and this reduce the pool of acceptable non-obese women.
I am almost sure that perception of women being “too fat” even for beta-males is entirely false.
For starters the obesity “epidemic” is primarily a problem among NAMs. Every day I see some massively fat black woman on the subway, but it’s pretty rare that I see a white woman with that body type. And of the few fat white women I know, they seem just as likely to be married as thin women (although their fat probably increases the chance that their husband has prole tendencies).
People work out a lot more today than they did 40 years ago (for example, Sean Connery was considered a “bodybuilder” back in the day, but he’d be skinny compared to most bulked-up modern actors), so some of the extra BMI that people have today compared to the past is caused by more muscle rather than more fat.
Modern orthodonture, as well as other types of medical improvements (such as better acne medicine and plastic surgery), means that women today have probably never been objectively better looking.
What’s different today is the abundance of high-resolution full-color images of Hollywood-perfect women. We are bombarded with these images in a way that wasn’t the case forty years ago. After seeing all of these images of perfect women, the average woman who is objectively is prettier than the average woman of forty years ago, subjectively seems less attractive.
