Can I be honest here? I prefer the type of - Samuel. Any type he is. I love him, I'm attracted to him, I want to have sex with him if he's overweight, has love handles, or has been working out. It makes no difference to me. I wouldn't want him significantly overweight because that would be bad for his health and would worry me.
So, when they did these surveys, did they check the physique of the man they were currently with? Women create emotional bonds, and they are attracted to the man they are bonded with, however he looks. Men tend to put on weight after they get married, I know Samuel did (my fault, I was excited to cook for my husband lol), so the more committed you are the more weight a guy puts on.
BTW, every one of these survey results articles that I read on different matters says that it's because of evolution. Right down to the stupidest of things (women can smell things better when orgasming and directly after sex because of evolution, so they'll know which man smells like their baby's father and can find him again in the tribe....for goodness sake). What a load of nonsense.
