Rebecca Lester’s book “Famished: Eating Disorders and Failed Care in America,” attempts to cover the medical communities’ Herculean efforts to cure a wide range of eating disorders. The book focuses on the complicated relationship between the attempts to treat those who suffer from eating disorders and the apparent failure of the system to heal them. And at its heart, Lester writes, “It is critical to understand that eating disorders are not about food—not really. They are about a deep, abiding, toxic shame and self-negation that is so embedded that it may never fully be eradicated.”
