| Abstract (English): | Objective: The eating behavior of individuals with eating disorders has been examined in laboratory settings over the last 30 years. In this focused review, we build on prior research and highlight several feeding laboratory paradigms that have successfully demonstrated quantifiable and observable behavioral disturbances, and thereby add rigor and reproducibility to the examination of disturbances of eating behavior. This review describes the measures commonly obtained via these laboratory techniques. Supporting Information Appendices with detailed information about implementation are provided to allow for the reproducible execution of these techniques across labs. Methods/Results: Literature documenting the existence of objective abnormalities in eating behavior among individuals with eating disorders or in comparison to healthy controls (n > 40) is briefly summarized. These protocols, conducted across at least 17 independent labs, are sensitive and reproducible, can be used to assess subjective and physiological parameters associated with eating, and elucidate the impact of treatment. Laboratory studies from patients with eating disorders compared with healthy controls reproducibly demonstrate both that patients with Anorexia Nervosa ingest fewer calories and that individuals with Bulimia Nervosa and Binge‐Eating Disorder ingest more calories when asked to binge‐eat. Discussion: Feeding laboratory studies have the potential for quantifying the characteristic behavioral psychopathology of patients with eating disorders, and may provide a useful tool to explore the potential utility of new treatments for individuals with Anorexia Nervosa, Bulimia Nervosa, and Binge‐Eating Disorder.

| Abstract (Spanish): | Resumen Objetivo Los comportamientos alimentarios de individuos con trastornos de la conducta alimentaria han sido estudiados en laboratorios por los últimos 30 años. En esta revisión enfocada, construimos una investigación previa y enfatizamos diversos paradigmas de alimentación en el laboratorio que han demostrado exitosamente alteraciones del comportamiento cuantificables y observables, y por lo tanto agregan rigor y reproducibilidad a la evaluación de las alteraciones del comportamiento alimentario. Esta revisión describe las métricas usualmente obtenidas a través de estas técnicas de laboratorio. Se incluyen apéndices con información detallada acerca de la implementación para la ejecución reproducible de estas técnicas en todos los laboratorios. Métodos/Resultados La literatura que documenta la existencia de anormalidades objetivas en el comportamiento alimentario entre individuos con trastornos de la conducta alimentaria o en comparación con controles sanos (n > 40) es resumida brevemente. Estos protocolos, llevados a cabo en al menos 17 laboratorios independientes, son sensitivos y reproducibles, y pueden ser utilizados para evaluar parámetros subjetivos y fisiológicos asociados a la alimentación, y dilucidar el impacto del tratamiento. Los estudios de laboratorio de pacientes con trastornos de la conducta alimentaria comparados con controles sanos reproduciblemente demuestran ambos que los pacientes con Anorexia Nervosa ingieren menos calorías y que los individuos con Bulimia Nervosa y Trastorno por Atracón ingieren más calorías cuando se les pide que coman en atracón. Discusión Los estudios de alimentación en laboratorio tienen el potencial de cuantificar las características del comportamiento psicopatológico de pacientes con trastornos de la conducta alimentaria, y pueden ser una herramienta útil para explorar el potencial de utilidad de nuevos tratamientos para individuos con Anorexia Nervosa, Bulimia Nervosa y Trastorno por Atracón.
