This article reviews the regulation of appetite from a biopsychological perspective. It considers psychological experiences
and peripheral nutritional systems (both episodic
and tonic)
and addresses their relationship with the CNS networks that process
and integrate their input. Whilst such regulatory aspects of obesity focus on homeostatic control
mechanisms, in the modern environment hedonic aspects of appetite are also critical. Enhanced knowledge of the complexity of appetite regulation
and the
mechanisms that sustain obesity indicate the challenge presented by management of the obesity epidemic. Nonetheless, effective control of appetite expression remains a critical therapeutic target for weight management. Currently, strategies which utilise a combination of agents to target both homeostatic
and hedonic control
mechanisms represent the most promising approaches.
