When Sophie (not her real name) was 14, she started developing an unhealthy relationship with food. She cut down on the amount and types of food she was eating, and became obsessed with exercising. “By the time I finished my exams, I looked gaunt; I only slept for a few hours a night, and I had not had my period for over two years,” she says. “My parents became increasingly concerned and took me to the GP who calculated my BMI. But because it wasn’t ‘low enough’ for me to be referred to an eating disorder specialist, they recommended I simply ‘eat more.'”
