INTRODUCTION

Although there was no female attractiveness effect when using the Bonferroni correction, we noted an interesting pattern in the unadjusted probability values. The leg-to-body ratio as a human aesthetic criterion. Body mass index classification misses subjects with increased cardiometabolic risk factors related to elevated adiposity. The most popular measure of female body curvaceousness is waist—hip ratio WHRthat is, the ratio of waist girth to hip girth.

Dashed line shows lower bound of healthy fat mass kg and solid attrsctiveness shows the upper bound of healthy fat mass kg for young women with the body mass of the average female subject identity in this study. Behav Ecol. Rothman KJ. This was true even when the variation in the two traits was held constant, Swami et al. Body mass index turned out to be far more significant than waist-hip ratio in determining the men's choices - redefining the ideal of sexual atttractiveness.

Body adiposity and type 2 diabetes: increased risk with a high body fat percentage even having a normal BMI. The 20 year excess probability of not having children, compared to the BMI class with the lowest rate of nulliparity, contributes to the negative effect of BMI on fertility.

The volume of each cylinder was the product of its height and the area of its base. Men and women prefer underweight, and frequently severely underweight, women. Women are expected to perceive the physical attractiveness of other females in a similar way to men so as to assess the mate value of competitors and to adjust their own mating and rivaling behaviors Dijkstra and Buunk ; Brewer et al.

In the present study, women preferred significantly lower WHR than men, which suggests that women put a higher premium on small waist versus small hips compared with men.
