The Psychobiology of an eating episode : are restrained eaters different

Abstract

The anatomy of an eating episode is influenced by various psychological, biological, and behavioural factors. The research has supported the existence of a biological correlate of satiety called salivary a-amylase (Harthoorn, L.F., 2008). The present study replicated and extended this finding to examine potential differences in levels of salivary a-amylase in unrestrained eaters compared to restrained eaters. According to the boundary model for the regulation of eating, restrained individuals have different experiences with respect to satiety compared to unrestrained individuals (Herman, C.P., & Polivy, J., 1984).
