『Anti-Diet』要約

In Anti-Diet, registered dietitian Christy Harrison argues that intentional weight loss is both biologically unsustainable and ethically compromised, positioning diet culture as a system that equates thinness with health and moral worth. Drawing on her background in nutritional science and her work as a certified intuitive eating counselor, Harrison traces the history of dieting in the United States from nineteenth-century weight-loss regimes through the rise of calorie counting, Weight Watchers, and contemporary wellness culture, showing how each wave has repackaged restriction as empowerment. Harrison introduces several frameworks that structure the book. The "diet culture continuum" describes how disordered eating behaviors exist on a spectrum, with rigid clean-eating and fitness tracking sitting closer to clinical eating disorders than most people realize. She also outlines the "health at every size" paradigm, citing research suggesting that weight is a poor proxy for health and that weight cycling, not fatness itself, may drive many of the metabolic harms attributed to higher body weights. Her "intuitive eating" principles, adapted from Elyse Resch and Evelyn Tribole, encourage attunement to hunger and fullness cues rather than external rules. The book examines specific phenomena including the "obesity epidemic" narrative, the marketing of diet programs to children, and the racial and socioeconomic inequities embedded in weight stigma. Harrison also discusses her own history of disordered eating and her departure from conventional dietetics, grounding the argument in personal and professional experience. Anti-Diet was published in 2019 by Little, Brown Spark and became a widely cited text within the body-positivity and intuitive eating movements.
