In January 2012, health reporter Tara Parker-Pope wrote a cover story for the New York Times Magazine titled “The Fat Trap.” The 5,500-word article, packed with pedigreed sources, explored the science of weight loss. Its conclusion? For most obese people, permanent weight loss is a pipe dream. The piece was widely disseminated — this was the Times, after all. It was broadcast on radio stations and television news reports, and big media outfits like National Public Radio and the Huffington Post interviewed Parker-Pope herself to spread the once-fat-always-fat message.
