Robust modeling of appetite regulation
Journal of Theoretical Biology, 2011The interaction between appetite activation and the energy content of the brain and the body is mathematically modeled. General influence functions with saturation are used to describe the interaction. The resulting class of models is investigated with respect to the circadian periodicity of human food intake. We show that very weak and physiologically

Appetite regulation and energy balance
Acta Paediatrica, 2005AbstractThe decision to begin eating or to stop eating is a complex process. Hunger is primarily driven by hunger signals, like ghrelin and neuropeptide Y, originating from the gastrointestinal tract and from the hypothalamus. The hunger signals stimulate the seeking of food and the eating, being activating for the body and mind.

Appetite Regulation by Gut Peptides
Annual Review of Nutrition, 1990A number of gastrointestinal hormones that are released from the gut in response to intraluminal food stuffs have been shown to play a role in producing satiety. Some of these hormones apparently activate ascending vagal fibers that send messages to the nucleus tractus solitarius, and perhaps from there messages are sent to the paraventricular nucleus ...

Hypothalamic neuropeptides and the regulation of appetite
Neuropharmacology, 2012Neuropeptides released by hypothalamic neurons play a major role in the regulation of feeding, acting both within the hypothalamus, and at other appetite regulating centres throughout the brain. Where classical neurotransmitters signal only within synapses, neuropeptides diffuse over greater distances affecting both nearby and distant neurons ...

Regulation of Appetite and Body Weight
Hospital Practice, 1997Short-term variations in caloric intake and energy expenditure-including attempts by obese patients to lose weight-tend to be modified by the body's long-term weight regulatory system. Hormones such as leptin and insulin participate in this system, which links changes in body fat content to appropriate compensatory responses in the hypothalamus ...

Appetite and the regulation of body composition
The FASEB Journal, 1994Stability of body composition requires that energy intake equals energy expenditure when integrated over prolonged periods. As recent human studies have failed to demonstrate active changes in energy expenditure with changes in body composition, it is likely that energy intake is continually adjusted to preserve a constant total adipose tissue mass. If

Gastrointestinal targets of appetite regulation in humans
Obesity Reviews, 2010SummaryThe aim of this paper is to describe and discuss relevant aspects of the assessment of physiological functions – and related biomarkers – implicated in the regulation of appetite in humans. A short introduction provides the background and the present state of biomarker research as related to satiety and appetite.

Effects of different modes of exercise on appetite and appetite-regulating hormones
Appetite, 2013The present study determined the changes in appetite and appetite-regulating gut hormones during and following bouts of both rope skipping exercise (weight-bearing) and bicycle ergometer exercise (non-weight-bearing). After a 12-h fast, 15 young men (mean ± SD, age 24.4 ± 1.7 yrs, maximal oxygen uptake 47.0 ± 6.5 mL/kg/min) participated in three 160 ...

Neuropeptide Regulation of Appetite and Weight*
Endocrine Reviews, 1987IN THE last decade, the explosive increase in our knowledge of neuropeptides has demonstrated that the release of peptides from the gastrointestinal tract can modulate behavior; and, contrariwise, gastrointestinal peptides have been shown to be synthesized and released in the central nervous system and act as neurotransmitters.
