Anna Wintour’s frank preference for the malnourished body type is admirable, at least, for its unflinching honesty. And while even the magazine editors who are most outspoken about body-acceptance might not put their concurrence in the printed word — Cindi Leive of Glamour comes to mind — they most certainly do so in the printed image. So you’d think Anna’s protege, Amy Astley of Teen Vogue, would take the easy route and simply follow in Anna’s smooth-as-glass wake. But noooo. Astley, to her major discredit, instead uses the obesity epidemic, of all things, as pro-ana justification in her editor’s letter this month: “Outrage over the boniest of celebrities and mannequins seems to obfuscate the more urgent and widespread story about Americans and weight: Only about 1 percent of women in this country are anorexic, while obesity looms as perhaps our greatest national health crisis.” Oh, I see. It’s cool to promote Auschwitz arms — and make vulnerable teen girls feel like dog poop — because such a small number actually get full-blown ana. Never mind that a huge number suffers from body-image issues. Nor that 99 percent of the imagery out there celebrates trainer-toned bods that run on less than 1,000 calories per day. Nor the responsibility one carries with a young readership whose socioeconomic standing places it squarely in the jutting-collarbone worship zone. But Astley, who truly wields the kind of the influence that could zap the pernicious skinny scourge among teen girls, cares more about her readers as commodities than anything else. Because if she really believed models “would be even more beautiful with a few additional pounds on their bodies,” then she would never run this skimpy shot of Kate Bosworth in a bikini, except as a lesson in how not to look healthy. Alas, it’s about summer beach bodies.
