A groundbreaking exploration of the relationship with food, body, and eating that decides whether weight loss lasts. Drawing on over two decades of clinical experience, Konrad reveals the central proposition: the weight was never the problem, but the symptom of something deeper. Grounded in Jungian and psychoanalytic thought, the book introduces the framework the whole series extends, from the Fat Head Phenomenon to the Unconscious Contracts the body makes on behalf of the psyche, and the argument that carries every volume: no change in behaviour holds without a change in the self, and the change that is understood is the change that lasts.
