What about you? If your priority is to reproduce and spread your DNA and we currently live in a society where brute force and rape will not ensure your genetic survival then why do you look like a fat piece of shit? Shouldn't you be doing the same?
What attracts women to sleep with men is very simple. You just have to pretend like you are paying attention to them and act like you are interested. For the sake of procreation I would select a woman who I would not be interested in fucking recreationally. I prefer fucking short girls with perky tits, but I would not want my own children to be short or skinny. I would want to reproduce with a chick who is 6'4" and good natural muscle mass. Someone scandanavian with ancestors who lived into their 90's or older, with low family history of cancer or other genetic issues.
Women select men who can make good providers for their offspring. Characteristics of alpha males generally carry over to these areas. This is because dominent alpha males usually are more capable of providing food (hunting) and fending off attackers. Society has changed faster than evolution so while this is still attractive on a genetic level, women are starting to identify money as the #1 attraction factor as this is what will provide for their children.
