Amazing but true:

Boston researchers determined that gay women were more than twice as likely as straight women to be obese, while gay men were 50 percent less likely to be obese compared to their heterosexual counterparts, according to a report published in the American Journal of Public Health. After scrutinizing a health survey of more than 67,000 Massachusetts residents between the ages of 18 and 64, the researchers found that 14 percent of gay men were obese versus 21 percent of straight men. The opposite was true of gay women: 26 percent were found to be obese, as compared with 17 percent of the straight women.

The reason gay men are thinner? Men—gay and straight—are total assholes:

That explanation makes sense to Esther Rothblum, a professor of women’s studies at San Diego State University. “People in sexual relationships with men—heterosexual women and gay men—get more pressure to look thin and to otherwise conform to attractiveness norms than do people in sexual relationships with women—lesbians and heterosexual men,” Rothblum said.... Other researchers have found further evidence of this male effect while studying personal ads and dating sites like, Rothblum explains. “Men will say they are looking for a partner who is not above 35 years old and not above 135 pounds,” she said. “Women don’t typically do that. They say they are looking for someone with good sense of humor, intelligence, and creativity, or someone who is not an alcoholic.”
