Abstract

Obesity is a condition where excess body fat accumulates to such an extent that one's health may be affected. Owing to the cardiovascular and metabolic disorders associated with obesity, and the epidemic of obesity facing most countries today, life expectancy in the developed world may start to decrease for the first time in recent history. Other conditions, such as anorexia nervosa and cachexia, are characterised by subnormal levels of adipose tissue and as with obesity lead to morbidity and mortality. Given the significant personal and economic costs of these conditions and their increasing prevalence in society, understanding the factors that determine the fat mass is therefore of prime interest and may lead to effective treatments and/or interventions for these disorders. Fat mass can be regulated in two ways. The lipid filling of pre-existing fat cells could be altered and the number of fat cells could be changed by the generation of new fat cells or the dying of old ones (i.e. adipocyte turnover). This review summarizes what is known about fat cell turnover in humans and the potential clinical implications.
