Energy homeostasis, autonomic activity and obesity

Obesity is often accompanied by alterations in both sympathetic and parasympathetic autonomic functions. The present paper summarizes the results of a number of studies designed to investigate autonomic functioning in normal, genetically, and experimentally obese rats, Particular emphasis is given to autonomic functioning and dysfunctioning in relation to the processes that are involved in the regulation of peripheral energy substrate homeostasis, It is concluded that alterations in autonomic regulation in obesity are determined by causal factors such as overeating, genetic make-up, age and/or the duration of obesity.
