Introduction: Ghrelin increases growth hormone secretion and food intake. Growth hormone (GH), steroid hormones and opioids are involved in the regulation of food intake. So, they may have a role in the regulation of ghrelin secretion. We determined the effect of intravenous injections of progesterone, GH and morphine or co-administration of these hormones on ghrelin concentration and body w...

Recent tremendous advances in our understanding of the regulation of food intake are expected to contribute to the treatment of obesity in the near future. The hypothalamus is a center for regulation of food intake and NPY/AgRP and POMC neurons are key regulators of food intake in the arcuate nucleus. The level of energy in the body is monitored by energy sensors in the hypothalamus. A variety ...

The gut plays a central role in energy homeostasis. Food intake regulation strongly relies on the gut-brain axis, and numerous studies have pointed out the significant role played by gut hormones released from enteroendocrine cells. It is well known that digestive products of dietary protein possess a high satiating effect compared to carbohydrates and fat. Nevertheless, the processes occurring...

The purpose of the present paper is to review recent theoretical developments in food intake modelling applied to animal science and ecology. The models are divided into those that have been developed for intensive agricultural systems, and those which consider more extensive systems and natural systems. For the most part the present paper discusses models that predict the food intake of herbiv...

Neuropeptide S (NPS) is a recently discovered peptide shown to be involved in the modulation of arousal and fear responses. It has also been shown that lateral ventricle administration of NPS causes a significant decrease in food intake. Neuropeptides involved in the modulation of arousal have been shown to be involved in the regulation of the hypothalamo-pituitary adrenal (HPA) axis and food i...

BEHAV. 8 (1) 127-134, 1972.-The interaction of eating and drinking and the relation between intake and body weight was examined in pigeons maintained under laboratory conditions in order to obtain normative data on intake and weight regulation in this Species. Under ad lib conditions fo...

Dynamics of body weight and food intake can be studied by temporally perturbing food availability. This perturbation can be obtained by modifying the amount of available food over time while keeping the overall food quantity constant. To describe food intake dynamics, we developed a mathematical model that describes body weight, fat mass, fat-free mass, energy expenditure and food intake dynami...
