Abstract

Body weight is determined by the complex interaction of caloric intake, absorption and utilisation of nutrients. Multiple factors (age, health status, neural, hormonal and metabolic influences, and medications) influence this interaction. The major site of this integration is represented by the hypothalamic area, where complex and specific neural circuits receive feedback from peripheral signals and coordinate the response in terms of stimulation or inhibition of food intake and energy balance [1] [3]. Among these peripheral signals, the adipocyte-derived hormone leptin informs the brain regarding the need to inhibit food intake and limit fat accumulation [4, 5]. In contrast, the gastric hormone ghrelin (see chapter by Broglio et al.) induces a sensation of hunger and is involved in energy homeostasis by inducing the storage of fat in adipose tissue [6].
