This is actually not true at all. The greeks often depicted overweight or "ugly" people, as did the Romans by the way. This is a statue of Aesop, one of the most revered Greek playwrights. why exactly he is depicted as ugly even though he was beloved, no one really knows: This is a statue of a drunk old whore: You will find that especially in the hellenistic period Greek art focussed more on social realism than on ideal forms. Also, you fundamentally misunderstand ancient greek culture in your interpretation. Ancient people were not depicted as beautiful because it was hot or because those were the body types they admired (I guess that, too), but rather because ancient greeks believed that being beautiful and good looking was a literal blessing of the gods and showed your good character. That's right, it's fundamentally about personality. That is also the reason why most of the heroes were good looking, because they received divine favor and had a good moral character. Consider the fact that even among greek gods, there are uglies: Hephaistos, Priapus, Pan, Geras, Achelous, all of which also had statues. Even ambiguous moral characters are represented through external beauty/ugliness, for example the Gorgons are clearly considered somewhat evil and described as having hideous faces, so ugly and hideous that anyone seeing them will turn to stone, but still usually depicted with enticing female bodies - After all they are neither completely monster nor human, they are something inbetween. There is a famous anecdote that a well-known Greek woman defended herself in court by showing her bare breasts and asking the "judges" if a person this beautiful could possibly be bad in character. They agreed with her that the beauty given to her by the gods was a surefire sign of her good character and ended up letting her go unpunished. So yeah, Greek statues aren't sexy because "sex sells, baby", but because it was a fundamental part of ancient greek culture to portray anyone you believed to be a good, moral person as physically beautiful. Zeus is considered beautiful even when he is a literal bull raping Europa. Greeks weren't zoophiliacs, Zeus just has to be beautiful.
