Appetite and adiposity: re-building a psychological theory of obesity Jane Wardle, Professor of Clinical Psychology, Department of Epidemiology and Public Health, University College London In 1968, in an influential paper in Science, psychologist Stanley Schachter proposed that obesity was caused by two abnormalities of appetite: low responsiveness to internal satiety cues and high responsiveness to external food cues. Externality Theory subsequently lost support in the face of evidence that restrained eating - rather than weight status - was the better predictor of appetite. For the next 25 years, restraint became the primary focus of psychological research into eating behaviour. This paper will describe a series of studies that have rekindled interest in externality. Based on new ways of assessing responsiveness to satiety and food cues, they present evidence for the heritability of appetite and show associations between appetite and adiposity in early childhood. Implications for treatment and prevention will be discussed.
