For many decades, the popular narrative surrounding anorexia nervosa was that it was an emotional disorder springing from profound cultural pressures combined with dysfunctional family dynamics. Teenage girls, typically, would refuse to eat in an obsessive bid to lose weight. They would imagine themselves to be fat, even if mirrors and scales demonstrated otherwise. Because of the surfeit of images of rail-thin preteen models cluttering the pages of trendy fashion magazines, it was easy to imagine this theory to be true. It made sense if some clinicians regarded anorexia as the inevitable result of a “you-can-never-be-too-rich-or-too-thin” culture.

饮食失调背后的生物学

几十年来，围绕神经性厌食症的流行说法是，它是一种情绪障碍，源于深刻的文化压力和功能失调的家庭动力。十几岁的女孩通常会为了减肥而拒绝进食。他们会想象自己很胖，即使镜子和体重秤证明不是这样。由于在时尚杂志的页面上充斥着大量苗条的青春期模特的图像，很容易想象这个理论是正确的。如果一些临床医生认为厌食症是“你永远不会太富有或太瘦”文化的必然结果，这是有道理的。
