Body shape and women's attractiveness : The critical role of waist-to-hip ratio.

This paper examines the role of body fat distribution as measured by waist-to-hip ratio (WHR) on the judgment of women's physical attractiveness. It presents evidence that WHR is correlated with a woman's reproductive endocrinological status and long-term health risk. Three studies were conducted to investigate whether humans have perceptual and cognitive mechanisms to utilize the WHR to infer attributes of women's health, youthfulness, attractiveness, and reproductive capacity. College-age as well as older subjects of both sexes rank female figures with normal weight and low WHR as attractive and assign to them higher reproductive capability. The study concludes that WHR is a reliable and honest signal of a woman's reproductive potential. The adaptive significance of body fat distribution and its role in mate selection is also discussed.
