just because girls that are heavy may not always be a fault of said girl, does in no way mean that a guy has to find that girl attractive. and to say that is a fault of guys is ridiculous. a man, genetically, has to find his mate attractive. a women doesnt have to be genetically heavy, (yes there are times that gemnetics plays a factor, but that isnt the point). to tell guys that they are foolish for not seeing past the heaviness of the wonderful personality that they are dating is akin to saying that when buying the house that has a roof that is half gone and a plumbing that is broken, well just you should look at teh wonderful community the house is in. now i am not saying that a heavy girl is broken. what i am saying is that men have certain criteria inorder for certain chemicals internally to activate. if a girl is heavy, and he is not into that, well then it is sheer stupidity to faulty teh guy. there are plenty of guys who do like heavier girls. just as there are guys who like blondes, brunettes and redheads. (ok noone really likes redheads 😉 ).
also the argument that skinny is just as unhealthy as heavy is ridiculous. there is a differance between skinny and anorexic, which most guys would find repulsive, probably more so then heaviness.
i hate always reading how guys should look past heaviness. its actually factualy impossible.
now if one wants to say that culture decides what is pretty, that has some truth in it, except thats not necesarily always true. some european cultures at times have found heavy women to be the attrictive ones, but that was not everywhere. asain, american (i mean the indigenous americans) and african countries have predominately found skinnier women to be attractive.
