What is satiety and how does it work?
Satiety involves a complex interaction of both physiological signals and psychological, environmental and social influences. The signals that influence the duration and intensity of satiety have been conceptualised as the ‘satiety cascade’ (see figure below). To add further complexity, satiety responsiveness varies between individuals.
What are the mediators of satiety signaling?
Primary mediators of satiety signaling form in the gastrointestinal tract, including CCK, GLP-1, peptide tyrosine tyrosine (PYY), and GIP (D’Alessio, 2008). CCK, a satiety hormone involved in controlling food intake, is released postprandially, particularly after fat and protein ingestion (Liddle et al., 1985).
What is satiation?
Satiation is the state of being sated and represents the cumulative effect of a variety of inhibitory sensory, cognitive, digestive, and hormonal signals that bring an eating occasion to an end; it is said to control meal size.
What neurotransmitters are involved in satiety?
Satiety is a sense of fullness after eating. The key neurotransmitters controlling appetite, at least in vertebrates, are serotonin (5-HT) and catecholamine. These neurotransmitters act to reduce feeding behavior and consequently food consumption.
How does the body signal satiety?
The prototypical satiation signal is the duodenal peptide cholecystokinin (CCK), which is secreted in response to dietary lipid or protein and which activates receptors on local sensory nerves in the duodenum, sending a message to the brain via the vagus nerve that contributes to satiation.
What is an example of satiety?
The condition of being full or gratified beyond the point of satisfaction; surfeit. Satiety is the state of having more than enough. An example of satiety is having just devoured plate after plate of food at a buffet.
What is satiety health?
Satiety is the satisfied feeling of being full after eating. Early satiety is feeling full sooner than normal or after eating less than usual.
What hormone is responsible for signaling satiety?
The two hormones most closely associated with energy homeostasis leading to sensations of appetite and satiety are ghrelin and leptin. Any shift in the delicate balance between ghrelin and leptin drastically affects our body's ability to regulate energy demands and storage, leading to pathophysiology.
What is another name for satiety?

What is eating to satiety?
Satiety is a term used to explain the feeling of fullness and loss of appetite that happens after eating. A scale called the satiety index measures this effect. It was developed in a 1995 study that tested 240-calorie servings of 38 foods ( 3 ). The foods were ranked according to their ability to satisfy hunger.

How does satiety occur?
Satiety refers to the afferent signalling that leads to cessation of eating. Satiety can be induced through physiological processes, including satiety-signaling pathways from the gastrointestinal tract to the CNS. More than 20 different regulatory peptide hormones are released in the gastrointestinal system. Many of them are recognized to be involved in the regulation of food intake and are sensitive to the gut nutrient content and composition (Murphy and Bloom, 2006 ). Primary mediators of satiety signaling form in the gastrointestinal tract, including CCK, GLP-1, peptide tyrosine tyrosine (PYY), and GIP ( D’Alessio, 2008 ).
How to define satiety?
Defining Satiety. Satiety can only be understood with respect to the entire appetite control system. Thus, the state of satiety is reached by consuming an adequate amount of food in a specific period of time. Food intake is driven by a powerful biological need to obtain sufficient energy to sustain life. However, meals are initiated ...
What is the mechanical distension of the abdominal wall?
Indeed, the mechanical distension of abdominal walls, in particular the gastric wall, is a potent satiety signal that is promptly relayed to the brain via neural afferents. Also, the presence of nutrients in the intestine inhibits eating and gastric emptying. View chapter Purchase book. Read full chapter.
What is SSS in psychology?
SSS is often referred to as a form of response habituation. With regard to the characteristics of response habituation (see Table 14.1 ), this makes sense. Repeated orosensory exposure leads to a reduction in liking for that food, with more exposure leading to stronger SSS (characteristic 1), and this reduced liking tends to recover over time (characteristic 2). The development of SSS can be delayed (characteristic 4) and, once established, shows some degree of stimulus generalisation (characteristic 7). However, SSS does not seem to be subject to dishabituation (characteristic 8). It is not affected by stimulus intensity (characteristic 5), at least not in the way that more typical response habituation is. Further, SSS is not potentiated (characteristic 3) with multiple opportunities to develop such SSS.
What is the state of noneating?
Satiety is defined as a state of noneating, characterized by the absence of hunger, which follows at the end of a meal and arises from the consequences of food ingestion.
What is the scientific concept of satiety?
Scientific Concept of Satiety. Satiety is specifically the inhibitory effect of dietary consumption on appetite. The decrease in hunger or thirst must, by definition, have been caused by some consequence of ingestion. In studies of satiety it is not sufficient to record satiety ratings alone.
Is SSS dishabituated?
However, SSS does not seem to be subject to dishabituation (characteristic 8). It is not affected by stimulus intensity (characteristic 5), at least not in the way that more typical response habituation is. Further, SSS is not potentiated (characteristic 3) with multiple opportunities to develop such SSS.
What is sensory specific satiety?
Sensory-specific satiety describes how as you eat more of a food, it’s pleasantness declines compared to that of other foods. In other words, you get tired of eating the same thing. In common parlance, ‘the dessert stomach’ describes how even though you’ve had enough dinner, you still have ‘room’ for dessert.
What is the satiety index?
The Satiety Index. The type of food eaten - including its nutrients and physical form - can influence satiety. Australian researchers were the first to publish a Satiety Index of common foods. The highest Satiety Index (SI) measured was for boiled potato and it was seven times higher than the SI for a croissant.
What is the state of being sated?
Satiation is the state of being sated and represents the cumulative effect of a variety of inhibitory sensory, cognitive, digestive, and hormonal signals that bring an eating occasion to an end; it is said to control meal size. Satiety is the psycho-biological process that suppresses hunger after an eating occasion and prevents further eating;
Why is aeration important for gastric emptying?
Aeration (bubbles) in a beverage promotes fullness and lower hunger than non-aerated (still) beverages independent of energy content and is thought to be due to carbonated beverages having greater gastric volume.
What is the difference between high and low energy density foods?
Energy density and satiety. High energy density foods tend to be palatable and less satiating, while low energy density foods (that tend to have the most water and least fat) tend to be less palatable and more satiating.
What is the role of taste in the brain?
Tasting delicious food in the mouth contributes to satisfaction of appetite, while triggering activation of the gustation (taste) and reward areas of the brain, suggesting sensory stimulation has an important role in satiation.
Does fiber increase satiety?
Dietary fibre in food promote satiety and reduced food intake and may explain the association between fibre intake and lower body weight. Fibre is thought to enhance satiety by adding bulk and viscosity to gut contents and altering gut hormones.
