This study is an acute, randomized, repeated measures design with 20 subjects. Subjects will consume 3 test breakfasts, white rice, brown rice, or glucose control, each containing 400 calories. Treatments will be one week apart. After consumption of the controlled breakfast, subjects will complete visual analogue scales (VAS) for satiety response. Additionally, they will consume a pizza lunch and record food intake for the next 24 hours. Breath gas samples will be collected to estimate fermentation of fiber in the large intestine. Also, subjective data on gastrointestinal tolerance will be collected ...

TY - JOUR. T1 - Appetite, hunger, and satiety in the elderly. AU - Rolls, Barbara J.. PY - 1993/1/1. Y1 - 1993/1/1. N2 - Food intake declines with age and the elderly frequently report a decrease in appetite. Social and physical factors as well as decreased energy expenditure may be part of the explanation for the decreased food intake; however, it is possible that changes in hunger mechanisms are also involved, but more studies similar to those conducted on thirst are needed. The consumption of a varied diet depends in part on sensory-specific satiety, that is, the decrease in the pleasantness of a food as it is consumed. We have shown that sensory-specific satiety changes with age such that it was absent in individuals over the age of 65 and this could be part of the explanation of why the elderly consume more monotonous diets. Additional basic studies on how aging affects the controls of food intake will suggest ways to improve the nutritional status of the elderly.. AB - Food intake declines ...
Forty-eight healthy individuals ≥18 years of age were enrolled in a randomized crossover trial. Following an overnight fast, subjects consumed either oatmeal or RTEC in random order at least a week apart. The breakfasts were isocaloric and contained 363 kcal (250 kcal cereal, 113 kcal milk). Visual analogue scales measuring appetite and satiety were completed before breakfast and throughout the morning. The content and physicochemical properties of oat β-glucan were determined. Appetite and satiety responses were analyzed by area under the curve (AUC). So they compared people eating oatmeal to people eating ready-to-eat cereal. Surprise! The people who ate oatmeal reported feeling less hungry later in the day. No kidding. Ready-to-eat-cereal takes your blood sugar on a wilder roller-coaster ride than oatmeal.. Now heres the studys conclusion:. Oatmeal improves appetite control and increases satiety. The effects may be attributed to the viscosity and hydration properties of its β-glucan ...

There is evidence of altered serotonergic and dopaminergic function and alterations in neuropeptides and gut peptides in AN and BN. It remains unclear whether abnormalities of neurotransmitters contribute to the development of EDs or are a consequence of the physiologic changes associated with the disorders. Patients with BN or BED appear to have a blunted serotonin response to eating and satiety. With a decreased satiety response, patients continue to eat, leading to a binge. Treatment with selective serotonin reuptake inhibitors (SSRIs) tends to equilibrate satiety regulation. An alteration in dopamine has also been recognized, although its significance is not clear. Adiponectin is elevated in AN, although it is unclear whether this is merely secondary to the malnourished state. Cholecystokinin is decreased in BN, perhaps contributing to the lack of postingestion satiety that perpetuates a binge. Ghrelin, a gut peptide, is elevated in patients with AN, and it does not decrease normally after a ...

Furthermore, elevated activation in taste processing regions of the brain to high-fat food tastes and elevated activation in a memory processing region to palatable food images were associated with future weight gain. The researchers speculate that an initial hyper-responsivity in taste processing regions to high-fat foods may increase risk for overeating a high-fat diet, which, in turn, may result in an attenuated sensitivity to dietary fat. In turn, a reduction in fat taste sensitivity may contribute to an impaired satiety response, resulting in excess high-calorie food consumption and unhealthy weight gain. These findings also suggest that avoiding weight gain by limiting intake of high-fat and high-fat/high-sugar foods avoids the blunting of taste and reward responsivity to food, thus reducing risk for future weight gain. Reference: Yokum S, Stice E. Weight gain is associated with changes in neural response to palatable food tastes varying in sugar and fat and palatable food images: A ...
Journal Article 2006; 27(1-2): 21-33 PubMed PMID: 16648819 Citation Keywords: Diet, Eating:psychology, Food, Humans, Motivation, Receptors, Opioid, mu:physiology, Reward, Satiety Response:physiology,. : Over the last decades, the importance of food in the development of chronic diseases has been examined, as well as the medical value of eating healthy. The contribution of the eating process itself to health and well-being, however, has not been questioned until most recently. Biology has linked eating to appetitive motivational processes with their underlying neurophysiology, including CNS reward circuitries: Eating uses the pleasure-reward physiology to motivate us to eat. Endogenous opiates, such as morphine, insure our survival by helping us to make eating motivational via pleasure induction. After taking in enough food, we become satisfied, i.e., tolerant to food. Our appetite, and so is our appetence, are then low and need a certain time span to reach their former levels for then inducing ...
Body weight depends on equality between food intake and expenditures of nutrients and energy. This balance is largely achieved by controlling the intake of nutrients based on the size and frequency of meals. Intake is assessed by a pattern of signals eminating from the digestive tract as a meal is in progress. The characteristics of the food and the products of its digestion are used to inform the CNS continuously as to the amounts of nutrient ingested. This information is in the form of satiety signals that may be chemical signals or nerve impulses. As the meal proceeds, these satiety signals become progressively stronger, until they cause the meal to end at an appropriate size. In the subsequent intermeal interval, these satiety signals weaken as nutrients are consumed within the body again until the tonic influences driving eating behavior initiate eating.. ...
Phosphatidylethanolamine (PE) is a phospholipid which is biosynthesized into long chain N-acylethanolamines (NAEs) including oleoylethanolamide (OEA), a known inhibitor of food intake. The aim of this study was to investigate whether PE-containing lipids can also inhibit intake. This was a 4 treatment intervention where 18 male participants were given a high-fat test breakfast (2.5MJ, 53 en% fat) containing (i) high-phospholipid, high-PE lipid (ii) high-phospholipid, medium-PE lipid (iii) no-phospholipid, no-PE control lipid or (iv) water control, in a randomised cross-over. Visual analogue scales (VAS) were used to assess post-ingestive hunger and satiety, and energy intake (EI) was measured at an ad libitum lunch meal after 3.5hours. When compared with the water control, the 3 lipid treatments resulted in lower levels of hunger and thoughts of food, greater fullness and satisfaction (all, treatment*time interaction, P|0.001), and a lower EI (P|0.05). However, there was no difference in any of the VAS

Feeling full or early satiety symptoms are quite common in stomach cancer. It tends to occur as the disease advances although there are other causes.
Introduction. Biological Explanations for Eating Behaviour The first study into eating behaviours was Canon and Wasburn (1912) they conducted a study in which the stomach would contract to indicate hunger and satiety. This research tells us that the strength of the gastric contraction correlated with the hunger and satiety of the participant. The participant was requested to push a button to indicate when they felt hungry. This shows that when we are hungry our brain sends signals to the stomach so that it can contract. A limitation of the study is that it contained one participant so it cannot be generalised. The part of the brain which receives signals of satiety is called the Ventromedial Hypothalamus it is located in the Hypothalamus and controls the amount we eat. ...read more. Middle. The hormone that is involved in signalling satiety is Cholecystokinin CCK which is the hormone released due to presence of food and sends signals to the VH to indicate satiety. CCK works when food passes from ...
Steve Bloom (London, U.K.) discussed satiety signals, noting that obesity is "key to the [insulin resistance] syndrome" and that it ultimately is caused by overeating. Childhood obesity is on the rise, with 40% of children expected to be overweight by 2010. He asked, what explains the reduction in hunger after a meal? Bulk in the stomach and nutrients in the circulation appear not to be the cause. There must be specific signals from the gut to the brain, neural and/or hormonal. It appears that, when stimulated, a small area in the proximal gastric fundus, near the esophagus, sends vagal signals mediating satiety. Studies have attempted to replicate gut hormonal signals by infusion, with cholecystokinin (CCK) decreasing food intake but causing pancreatitis and acting as a growth factor for pancreatic acinar cells, which could cause increased pancreatic cancer risk. Ghrelin decreases after meals and may be a negative satiety signal, as its direct effect is to stimulate food intake. Pancreatic ...
Author SummaryWhy do rats, people, and many other animals eat in bouts (meals) rather than continuously? How are they able to regulate not only total intake over a long period, but also within a meal? Is there a simple physiological explanation for these facts? We introduce a feedback model for eating regulation that can be readily interpreted in terms of existing neural data. We show by experiment and a theoretical model that eating in meals is regulated by a simple control system, like a house thermostat. In an experiment, we studied the meal patterns in rats after an interruption in food availability just as the animal tried to start a new meal. The results of this type of experiment cannot be explained by existing homeostatic approaches. We propose a simple model that combines long-term regulation (over months and years) by signals that reflect metabolic conditions, providing the set point for negative feedback, and short-term regulation (within a meal or a day) by feedback from the delayed
To this date, the most satiating thing was peanut oil. The amount required to fill a days calories does not look a lot, but you have to force yourself to keep going, and it makes you never want to put a thing inside yourself again. Its weight-reducing too, like butter, olive oil, other nut oils, and cream. Maybe there was a Seth Roberts neat oil effect. The one foodstuff I cannot do the same experiment with is green or other light vegetables, because the necessary bulk would be too great to eat in a day. But this does back up the finding of the Satiety Index that high-bulk foods are the least likely to be overeaten. As a result of my little tests, I now eat such vegetables with oils and cream, to make them more palatable. Im not afraid of fatty food, if the fat is good fat--but I dont go near junk food, which is designed to be overconsumed. ...

Fortunately, for those of us who prefer to eat solid than liquid food, there is the mighty mono food diet. Kitchari is used as an Ayurvedic detox food that also is believed to foster spiritual growth in its native India. Kitchari is the Sanskrit word for mixture and is used to describe any dish that is made with beans and rice. Originally it was used to feed the sick, the elderly and babies due to its high digestibility. The purpose of the diet is similar to the goal of juicing with some added benefits. First of all, the food has substance, so it is high on satiety, which is the feeling of fullness and satisfaction we get after eating a meal. The higher the satiety the higher the leptin levels which stave off hunger for longer periods of time and prevent overeating. This makes it a perfect weight loss food. If you have any gastrointestinal issues, it is an excellent diet for healing and repair of inflammation. Mono diet means you eat the exact same food for a period of time, up to about a week. ...

Feeding is an innate behavior in the animal kingdom. Proper amount of food consumption is critical for survival and health, as well as for producing high-quality progenies. Although appetite signals for promoting eating have been widely investigated, the mechanisms underlying feeding termination are poorly understood. On Jan 19th, 2017, a research paper entitled "Drosophila FIT Is a Protein-specific Satiety Hormone Essential for Feeding Control" in the journal of Nature Communication addressed this important question. Animals consume food containing essential amino acids daily, and deficiency in protein consumption leads to severe developmental defects. On the other hand, a bunch of evidences have shown that excess protein intake results in stresses in organs, like kidney and liver, the acid-base imbalance, and even severe diseases, such as renal failure. Among the three macronutrients, protein exerts the greatest inhibitory effect in feeding control. Nevertheless, protein-specific nutrient ...

Two foods, one rich in protein (HP) and one rich in fat (HF), were employed to evaluate the effect of macronutrients on food intake and to underline the differences that occurred when the foods were served as uniform meal, as first course of a varied meal, and as a snack 2 h before a varied meal. Our results showed that HP food always exerted a higher effect on both intrameal satiation and postingestive satiety than HF food. When a uniform meal was consumed, satiation for the specific food was reached before fullness; in this condition, sensory characteristics of foods played an important role in controlling food intake and made the uniform meal more satiating than the varied one. The consumption of a snack far from a meal did not contribute to satiety; consequently, gastric filling seems to be an important factor determining the amount consumed in a varied meal. ...
Summary: A new study reveals the molecular switch that helps control the function of satiety neurons and body weight.. Source: Helmholtz Zentrum München.. Obesity - as research in the past decade has shown - is first and foremost a brain disease. Researchers at Helmholtz Zentrum München, partners in the German Center for Diabetes Research, have now discovered a molecular switch that controls the function of satiety neurons and therefore body weight. The findings were published in the journal Nature Metabolism.. The worldwide epidemic of obesity has reached record levels, and what was once a problem only of industrialized countries is now also affecting the developing world. Consequently, scientists are working with great commitment to identify the mechanisms underlying the disease in order to find new treatments. Researchers at the Institute of Diabetes and Obesity (IDO) of Helmholtz Zentrum München have recently taken a further step in this direction.. Yin and yang of energy ...
Our overall research program is aimed at identifying the roles of various neural signaling pathways in the controls of food intake and body weight. The current research takes a number of approaches. The first involves the identification of the neural representation of meal-related satiety signals. Multiple feedback signaling pathways are activated by food ingestion and the gastrointestinal presence of digestion products. We are examining how signals from multiple sites and stimulus modalities are integrated within specific brain nuclei and, in an effort to model eating disorders, how alterations in feeding patterns can influence these neural representations.. The second approach involves the identification of interactions between peripheral, within-meal, satiety signals and hypothalamic peptide systems involved in overall energy balance. We are currently examining how the activity of hypothalamic leptin, NPY, CCK, CFR, CART and melanocortin systems interact with ascending satiety pathways to ...

The primary purpose of food is to satisfy hunger, provide energy, and supply our bodies with essential nutrients. Although we also choose what we eat based on taste and personal preferences, it is important to have a strong foundation of satiety-boosting and nutrient packed foods in our daily diets. What is a satiety-boosting food? Satiety-boosting foods are ones that are rich in fiber, healthy fats, and protein. They are digested slower, thus keeping us fuller for longer. On the other hand, foods high in refined carbohydrates, such as white bread and sugar-sweetened beverages, offer very little satiety and often lead to overeating. To build your foundation of satiety-boosting foods, check out these super-filling options. Pulses, avocados, and nuts increase satiety Pulses-also known as beans-are a Read More , ...
Did you know that when you evenly consume at least 90 grams of protein over the course of three meals per day, maximal protein synthesis is stimulated and there is a marked improvement in satiety. As a result, calorie consumption is better managed throughout the day. Plus, the muscle building properties and recovery after a workout are enhanced with appropriate protein intake. Youll not want to miss this video as we take a closer look at protein.

The metabolic stress that is a hallmark of modern life, the stress that the body has not evolved to handle, is constant eating, he continues. When people eat, energy and nutrients enter the body rapidly, are processed, produce in turn a lot of by-products, and then need to be reduced to "functional substances that are distributed throughout the body, and then disappear very quickly. Many cells and tissues actually undergo a huge amount of stress during this process," he explains, "as they store appropriate nutrients and dispose of harmful intermediates." Part of this process also involves mounting an immune response. "The pancreas, for example, must secrete four to five hundred milliliters of enzymes every day" to be able to manage the incoming energy load with every meal. "If you place these organs under constant stress, they start malfunctioning." The consequence is that "right now, one out of every 10 individuals has diabetes. One out of every four individuals has fatty liver disease. And if ...
The term full stomach is also commonly used to mean that we have already eaten, irrespective of whether it was a large or small meal. A person may not have the full stomach feeling but since they have just eaten, they may still use this term. Irrespective of the manner in which it is used, stretching of the stomach wall, easing of the hunger pangs and feeling satisfied after eating a meal are all normal sensations that we encounter everyday in life.. However, there are instances where we experience that full stomach feeling which is quite uncharacteristic like after eating only a few bites. This is known as is known as early satiety (easy satiety) or postprandial fullness. The feeling may even occur and persist despite not eating. This is known as bloating (bloated sensation). It can be an important symptom of some underlying problem, usually of the stomach and small intestine.. ...
Whether these cells express insulin receptors to facilitate ingress of substrate is something to be picked at. As I am completely biased against the concept that insulin is a satiety hormone, I would prefer this not to be the case but may be wrong. Time will tell. It looks logical to me that the brain would look at the nutrient levels present in excess of those being disposed of by peripheral insulin in to peripheral cells. As large numbers of peripheral cells become "full" under the influence of insulin, the brain should pick up the rising level of excess nutrients as the signal to call a halt on hunger. Doing this within the brain shouldnt need insulin, merely a set of relatively low affinity transporters to allow glucose and lipid uptake as insulin completes its peripheral function. Satiety should be picked up when enough cells have enough calories, whole body, that they no longer behave as a calorie "sump". The job of the brain is to pick up evidence from the nutrient levels that the sump ...
