I think the media has the female perspective so screwed up it is ridiculous! How heavy is too heavy? How thick is too thick? Do guys like thick or skinny girls? You never hear people say, "How healthy is too healthy?". Today people are so fixated on looking thin and loosing weight that they loose focus on the health aspect of their personal image, or their body image.
What is body image? Body image is a multidimensional construct or an idea that reflects how you see your own body. Many and most people today experience body image disturbances even if they are not aware of it. Body image disturbances are inaccurately perceived images that you may see as you are looking in the mirror . There are four body image dimensions which are perceptual, cognitive, effective, and behavioral. I will not go into depth on these right now, but that should give people something to look up if it sounds like something they are experiencing. My minor is Exercise Science, so I had to put some of that out there.
Do guys say, " Look at that fat/heavy chick, I'd tap that"? No, and I hate when guys say crap like that. No, guys do not typically go for girls who unfortunately have an abnormally high Body Mass Index (BMI). That is not something most guys look for in a girl. Do guys want the thin, twig like supermodels? Absolutely not, that is disgusting and the media has it all wrong across the boards! Personally, I like girls who are in shape and make a real conscious effort to stay in good shape. Being physically active is not a choice, its a lifestyle. Most guys like their women to be healthy and last time I checked, heavy and fat are not new slang terms for healthy.
So not to be shallow. But yes, weight does matter. And unless it is a result of a Thyroid condition, you can always improve your physical condition and get into better shape. Women should really stop asking this question. It is unfair and just make us guys look bad and shallow minded. If some sweaty, stinky, overweight guy walked up to an attractive girl and asked for her number, we all know there is most likely no chance in hell he will be successful. Girls often ask men as well, "If I gained weight and got fat, would you still love me". That is a horrible and unfair question to ask a boyfriend or a spouse! Love is also respect, and how can we (men) respect you if you do not respect yourself. Someone who respects and cares about themselves will take care of their body and continue a healthy lifestyle.
Finally, yes weight is huge...Literally! And it should matter just as much for the women asking this question as the men looking or not looking. Yes, beauty is only skin deep and in the eyes of the beholder. Everyone has their own idea of beauty and definition of what beauty looks like or if it is about looks at all. That is your call as an individual. Weight does matter, but as long as you are healthy anything some asshole says about your weight is irrelevant.
