A number of hypotheses can be raised from the raunchy and graphic, to the sexist and chauvinistic, via the quasi-medical and scientific. From all I have read so far, nobody seems to wonder whether these lesbian women became obese over the years AFTER they came out of the closet; or did obesity lead them somehow to become lesbians, or was a contributing factor. Whereas the former could be attributed to nurture and environment, the latter could suggest some genetic linkage between obesity, homosexuality and the X chromosome. Or it maybe a default or forfeit situation: the ones who are too fat to “catch” a man just settle for women.
Are people in sexual relationships with men, heterosexual women and gay men, more under pressure to look thin and attractive than do people in sexual relationships with women, lesbians and heterosexual men. Is that because MEN ARE FROM MARS? Around men’s libido, there is usually more of a “hunt” going one, more of a studly behavior, hence the trimmer figure. Does heterosexual sex also burn more calories...or is it just a PHALLACY?
However, there seems to be increasingly strong evidence for a genetic link between obesity and sexual behavior. We know obese men’s morphotype can look a bit female (gynecomastia, shrunken penis, fat rolls in mid section). The obesity of the type II diabetic reminds us that Insulin is a Yin (female) hormone. It makes one gain weight. So do most anxiolytics like Paxil, Prozac, Lexapro that are much more often taken my women than men. Are these more often taken by lesbians? That will certainly be part of the explanation.
Be that as it may, one meaning of the word lesbian derives from the poems of Sappho, who was born in the island Lesbos and who wrote with powerful emotional content directed toward other females, making her the spiritual leader of the lesbian movement. The third-century philosopher Maximus of Tyre wrote that Sappho was "small and dark" not obese, and that her relationships to her female friends were similar to those of Socrates (with his male friends of course).
Lesbos is one of the Greek Islands. It is forested and mountainous with two large peaks, Mt. Lepetymnos at 968 m and Mt. Olympus at 967 m, dominating its northern and central sections. The island’s volcanic origin is manifested in several hot springs and the two gulfs. A helicoptered view evokes a female body with the two equal mounts and the golf below (see picture). Maybe the Greek Gods on Mount Olympus wanted it this way.
I can imagine what Sappho could say to her American woman lover:
