The math doesnt check out with what you're saying though. Obesity rates are similar for both men and women within a few percent.  To simplify what I'm saying, let's take an imaginary island with 100 men and 100 women in it. Around 30 of those men are thin or fit. Around 30 of those women are thin or fit. How exactly would the women be more in demand? Unless you mean the attention they're tripping over is from fat men, the math would show human men and human women are roughly as scarce as each other, and in the same approximate demand as each other. I could be wrong, but with overweight and obesity rates being similar across genders what you're saying doesn't make sense to me. (Pls don't pull a Tumblrina and take it personal I disagreed)
