Satety obesity is affecting people sattiety all socioeconomic levels in most Caloricc the countries worldwide. Appetite intaie satiety Visceral fat and gallbladder disease complex anx which influence the energy regulation.
As a solution to enable individuals to saatiety their body weight, functional foods were developed in order to reduce Calloric energy intake.
However, the sateity to assess Calric satiating Glycogen replenishment for muscle repair of functional foods, including monitoring through biomarkers, is very complex and needs to be standardized.
Nowadays, the research Creatine and cardiovascular health the regulation of food intake in human is on the aand, considered as the Calooric focus to intale a possible Cxloric of the high prevalence of obesity and non-transmissible chronic diseases in the abd population.
The actual life style, characterized by the consumption of high energy density foods and a low level of physical activity in several populations, is the main cause of these health problems. The main Sports supplements guide of this obesogenic Caloric intake and satiety is a positive energy satkety which represents the basis of the Techniques to reduce muscle soreness prevalence of overweight and obesity.
Furthermore in several studies, conducted satisty low income families, the snd of high carbohydrates and low dietary fiber diet was demonstrated [ ssatiety6 ]. This Alpha-lipoic acid for weight loss of diet, determines a Healthy eating habits enzymatic digestion, Enhanced mental agility, increasing glycemia levels and Alpha-lipoic acid for weight loss a low satiety [ 78 ].
At ontake same time the Calorci amount of dietary satietyy is associated with safiety poor sqtiety management untake 9 amd, 10 ]. A possible dietary solution Caloric intake and satiety control the obesity rate safiety to ihtake the intake of common foods datiety high satiety potential.
In the last years functional foods which include ingredients with a high potential to produce a strong feeling Enhanced mental agility fullness were Cxloric. The efficacy of these foods must be evaluated intakke clinical trials performed in humans and accepted by regulatory organisms Halford Jc, The importance of Caliric foods in the actual population feeding is essential intakd control the energy Caloric intake and satiety process.
This latter regulation is based on Superior natural fat burner biological events between the peripheral gastrointestinal tissues and the central nervous system, which Snakebite emergency protocol the information and controls Caliric process.
Also the energy regulation is affected by the environmental factors [ 11 ]. For these reasons, the Body shape psychology designs and the procedures applied to study the efficacy of sstiety foods in the energy intake regulation, represent satifty factors for industrial, consumer and scientist Analyzing water percentage. This Mindful eating for energy is valuable to provide a background for the discussion of conceptual and practical Caloirc considered in the development of functional foods.
Intzke models proposed to study the regulation of Cwloric intake indicate that food intake starts with external signals related to Immune-boosting recipes metabolism Grape Vineyard Design Ideas. On the other side, the Caliric of satiety is sariety to an elevation of plasma cholecystokinin CCK and insulin in anf central nervous system.
Both biomarkers are associated to the surfeit satiey [ 14 ]. During the consumption phase, food intake is controlled by ane, cognitive and Probiotics for joint health effects [ 1516 ].
Term intakf is led primarily by the food Quinoa side dishes in Enhanced mental agility stomach and by satifty chemical composition snd the small intestine [ 17 - Caloruc ]. The inrake frequency consumption abd another important factor satietyy the food intake regulation, because it is aand related to the cell energy status.
The feeding frequency increases when cells satietty in energy deficit [ 20 ahd. From a adn perspective, the biochemical reactions originate signals captured by the central nervous system, leading to the sensation Concentration and focus in a digital age appetite or fullness recognized by the subjects.
However, the selection saiety foods and the amount of energy consumed by individuals are strongly conditioned by dietary eatiety. For example, the culinary processes and the ingake are involved in energy regulation [ aand ].
In addition it is well established Insulin sensitivity management other nutritional variables such as energy density, macronutrient content and variety of Caloric intake and satiety offered during a watiety time, can modulate energy intake [ 22 - inyake ].
The terms more Calorc to identify the different biological state that express the energy regulation are appetite, satiation inyake satiety.
Appetite can be defined as satiett internal state that Post-workout nutrition for improved athletic performance a strong motivation to eat when foods are available.
Imtake the Olive oil industry eat, some Dairy-free bread influence satiwty ending of the feeding, satiegy a feeling of fullness and satiation [ 2526 ].
Each meal is followed by a variable time period characterized by satuety absence intaje hunger, defined as a state of repletion Restoring skin elasticity energy that sahiety after a meal [ 27 ].
Cooking with onions length of inter-meal period is known as satiating efficiency which is specific for each food or Alpha-lipoic acid for weight loss combinations [ 2829 ].
Satifty intake of foods with elevated satiety efficiency also decreases the number of eating episodes during intakr day, thus reducing food and energy intakes [ 3031 ].
The sequence of events shown in Fig. Furthermore, the food intake regulation is influenced by multiple factors beside the biological factors such as psychological, socio demographic, cultural and individual factors [ 1134 ].
The methodology approach applied in most of the researches on appetite and satiety is varied and complex because of the numerous variables involved [ 313536 ]. Consequently, the results obtained from these studies are related with the experimental design applied and the derived conclusions have to be carefully interpreted.
The methodologies used in most of the reviewed studies for the development and evaluation of functional foods, designed to increase satiety, are divided into three stages Fig. At this stage it is necessary to define the functional ingredient, the dose and the selected vehicle food.
The second stage corresponds to the evaluation of technological processes applied to obtain a functional food ready to be developed industrially. At this stage, it is necessary to handle technological functionality of the food to achieve high acceptability and sensory characteristics.
The third stage is the application of a clinical methodology to evaluate the satiety potential of the functional food through various experimental designs.
Experimental design to develop and assess the efficacy of functional foods in satiation and satiety. The acronym VAS stand for Visual Analogue Scale. One of the designs most frequently used to evaluate a short term satiety consists of the assignment of a preload test where subjects have to consume the whole of a small portion g [ 36 ].
After a brief period of time 30 or 60 minutes the amount of food that subjects are able to eat is measured or the perception of satiety assessed using the Visual Analogue Scale VAS [ 3738 ]. This method is used to determine the short-term satiety: the participants are asked to specify their sensations of hunger, satiety, fullness, and desire to eat in a particular features, using this scale of values from 0 to 10 centimeters [ 39 - 41 ].
It is advisable to use the VAS before starting the trial, immediately before and after the consumption of the test food and at minutes, to compare the results with the measurements of plasmatic biomarkers, such as glycemic response. Another experimental design to assess the satiety potential of the functional food is to include it in a meal time, such as breakfast or lunch.
After 3 hours, the satiety was evaluated determining the subsequent intake or using VAS [ 36 ]. In both designs, preload or meal time, foods are supplied in pre-weighed portions beyond the energy requirement of the subjects.
Three ways to provide food are available: fixed, varied or freely. In the first case, a unique preparation in an amount greater than normally consumed are offered, with the possibility to give more to the subjects if requested.
In the varied offer mode, 5 or 6 foods with different nutritional and orosensorial characteristics, such as a salad, a stew, a glass of juice or drink, a piece of bread, a serving of fruit and milk dessert are offered. Other authors prefer to use different types of sandwiches accompanied by portions of fruit and liquid foods.
In the freely offer mode, the food is served on a table and the subjects could take as much as they liked. In this design a lot of small portions of several foods are offered, taking care to strike a balance between different sensory characteristics of sweet and savory foods, liquids, gels and solids foods, meat and vegetables, dairy products and baked goods.
Total food intake is determined by differential weighing which compares the amount of foods offered and the amount left over by each subject [ 35 ]. There are many studies that only measure satiety by the VAS without the determination of the food intake in the subsequent meal. The three methodological stages described in the Fig.
Nevertheless, in each stage it is important to constantly create a valuable feedback for the optimization of the whole process. In each stage of the experimental design it is necessary to take into account a large number of variables.
For example, in the intervention stage it is necessary to essay different doses of the bioactive compound to obtain an adequate satiation and satiety potential and a good sensorial and technological quality in the functional food. The scientific literature shows that for the same bioactive compounds, clinical studies use different doses.
Thus, there are studies that essayed elevated doses to assure the beneficial effect of the compound and others studies are interested in essaying a minor dose which can be found in normal food portions.
It is necessary to control also the amount and the type of macronutrients, dietary fiber, phytochemical and other food compounds that could affect satiety and accompany functional ingredient studied. On the other hand, technological and culinary treatments influence satiating efficiency of foods.
For example, the gelatinization of starches in cooking water drastically reduces their satiating effect [ 742 ]. Additionally, physiochemical changes in food matrix such as texture, viscosity and consistency are detected when foods are industrially or culinary treated [ 4344 ].
Moreover, the sensorial characteristics of foods can also affect their ability to produce satiety. Some authors showed a correlation between brain activity in the regions that control food intake and the rate of pleasantness [ 45 - 47 ]. Consequently, the nutritional, sensorial and physiochemical characteristics of food must be paired or controlled and the results published frequently did not show an adequate control of the experimental variables.
The various ways to offer food are appropriate for different: the fixed supply is suitable for subjects with small gastric capacity, like preschool children. Instead, offering varied or freely designs are more appropriate for adolescent and adults.
In these latter two, the concept of sensory-specific satiety is used; it means that the subjects can obtain satiety for one type of feed, still maintaining an appetite for foods with different characteristics [ 48 - 50 ].
The variety of textures, tastes, smells and colors is also involved in this phenomenon [ 163351 ]. During a meal, the absence of varied choice tends to limit food intake, whereas variety tends to promote eating. Therefore, in this design it is very important to get a good balance between the physiochemical, sensory and nutritional characteristics of food offered.
In this way, subjects can express their real potential capacity to consume. Regardless, the three ways to offer food fixed, varied or freely should all include foods with high acceptability by the subjects involved in the study.
Another important aspect to evaluate the satiating potential of a functional food or ingredient is to standardize the hunger level of each subject, regulating the fasting condition of the previous days. The time between the ingestion of functional food and the measurement of satiety change, basing on the purpose of the study.
If the aim is to evaluate the effect of the oro-sensorial and gastrointestinal factors on satiety, the delay should be no more than 30 minutes, while if the purpose is to investigate the inhibitory effects post-absorptive, the delay must be longer.
The review of published studies shows that there are two methods used for satiety measurement. The first evaluates the perception of satiety reported by the participants and the second measures the actual food intake.
Therefore, the VAS provides a subjective evaluation of satiety while the measurement of actual food intake provides an objective assessment. Both methods are widely accepted in satiety assessment and can be considered as markers to evaluate the direct effects of food intake [ 38 ].
Some variables that must be considered during a study are the environmental conditions in which results are obtained. The laboratory conditions are more appropriate to have an adequate control of the different variables while the free-living conditions are similar to the normal way of eating of the subjects.
When the objective of the study is to obtain physiological responses or to study the conceptual framework of some biomarkers, the research must be carried out in a laboratory context. On the contrary, if the aim of the investigation is to determine the effect of food on body weight changes which requires a long period of time, it is more appropriate to perform the measurements in a free-living environment.
In both approaches the environmental conditions need to be considered in the interpretation of the results and in their projection to the feeding of the individuals. The experimental researches in the field of energy regulation need to study different compounds derived from the metabolism of macronutrient or peptides in the cells, acting as messengers from the gastrointestinal tract to the central nervous system, principally in certain regions of the hypothalamus.
These biomarkers help to understand how the processes of satiety and appetite are modified by the dietary components, contributing to reach an optimum in the usefulness of the functional ingredients designed to increase satiety.
The metabolic biomarkers are simultaneously determined with the measurement of satiety. These biomarkers may provide valuable information to explain the conceptual basis to understand the effect of dietary bioactive compounds on human cells.
Some researchers recommend the determination of Cholecystokinin CCK and Glucagon-Like Peptide-1 GLP1 as markers of satiation and the measure of glycaemia, insulinemia, Gastric Inhibitory Polypeptide GIP and Peptide YY PYY as biomarkers of satiety [ 52 ].

| Introduction | Many factors influence our feelings of fullness and the amount of food we eat including our mental state, sleep patterns, physical activity, genetics, and hormone sensitivity. Food form the physical state of the food: either in solid, semi-solid, or liquid also impacts how much we eat. The effect of food form on satiety the physical feeling of fullness , satiation the end of desire to eat more after a meal, which can occur at any time after the onset of eating , and overall caloric intake is an important topic as nutritionists and food processors search for ways to help the public avoid over consuming calories. The role of food form in satiety and caloric intake has been studied in various ways. One systematic review on the role of liquid vs. solid carbohydrates found that liquid carbohydrates are less satiating than solids, and food intake is not adjusted when calories are consumed in sugar-sweetened beverage form. Chewing whole food has been thought to increase physiological responses, which lead to satiety. Whole foods are more slowly digested than liquids, so gastric emptying has been studied in relation to satiety. Humans may have expectations that a food, which appears more solid, will be more satiating than a liquid. All 16 primary research papers in this review are randomized cross-over or partial cross-over studies. Two of the papers focus on older adults and one study was on adolescents. Solids were found to be more satiating than liquids in 11 of the studies. Four of the studies found food form had no effect on satiety , and two studies found liquids were more satiating than solids. Most of the papers also tested additional measures such as food intake, the difference between lean and obese participants, and appetitive serum markers. Of the 16 total papers reviewed, 11 studies found solid food to have a stronger effect on satiety than beverages. Of the nine that measured intake, five found that solid preloads led to less food intake at an ad libitum meal 7,8,11,13,14 and the four of the studies found that solid food form led to stronger feelings of satiety, but there was no effect on food intake. Of the studies that found solids to be more satiating than liquids, measures other than food intake were investigated. Three looked at the difference in satiety response or caloric intake between lean and obese, 6,9,13 and four studies also looked at insulin, glucose and other serum markers. Studies showing solids are more satiating that also looked at food intake. Nine studies that found solid foods are more satiating also measured food intake at an ad libitum meal following the test solid or liquid. Five studies found that a solid preload lead to less caloric intake 7,8,11,13,14 , and four studies found that food form of preload had no effect on food intake of a test meal. Studies showing solids are more satiating and also found solids decrease food intake. The five studies that found solids to be more satiating and found a solid preload to be more satiating than a beverage preload were Cassady et al , Yoemans et al , Flood-Obbagy et al , Houchins et al and Hogenkamp a et al. In all studies except Hogenkamp a et al , participants were given a test food of either a solid or liquid, asked about their feeling of satiety then, after a set period of time, given an ad libitum as much as you can eat meal. The Hogenkamp a et al study tested intake on the actual test foods no on a follow up meal after a preload. Cassady et al and Houchins et al offered macaroni and cheese, while Yoemans et al offered pasta and ice cream and Flood-Obbagy et al served cheese tortellini with tomato sauce. Total intake of the meal was measured, and in these four tests, researchers found that those who consumed a solid test food consumed less of the ad libitum meal. Hogenkamp a et al also found that participants consumed more with the liquid test, even though the methods of their experiment differed. The 52 healthy adults in Cassady et al, were exposed to four different preload foods. Yoemans et al tested thin and thickened energy drinks on 48 healthy adults over multiple days. In a study by Hogenkamp a et al, the differences in expected satiety and intake after repeated consumption of liquids and semi solid foods were tested on 53 healthy adults. All five studies above, which showed that solids were significantly more satiating than liquids and led to less intake, were relatively small, ranging from the largest of 58 in Flood-Obbagy et al to 34 in the Houchins et al study and involved adults of normal BMI, except for the Houchins et al study, which compared the results from 15 lean and 19 obese adults. Studies that showed solids are more satiating but food form of preload had no effect on intake. Four studies found that, although solid test foods produced more satiety, intake of the ad libitum meal was not affected by food form of test food. In Mattes et al, the test food was apples in the whole, semi-solid applesauce , and liquid juice form. The Apolzan et al study tested the difference in solid meal replacement bars vs. liquid meal replacement beverages of the same nutritional content. The Hogenkamp b et al study tested learned satiety over time with a high energy HE vs. low energy LE in beverage or semi-solid form over several consecutive days, followed by an ad libitum buffet lunch. Zhu a et al studied the difference a standard viscosity custard and high viscosity pudding meal. custard Studies showing solids are more satiating than liquids, that compared responses between lean and obese. Of the studies that found solids to be more satiating than liquids, two studies compared lean and obese adults 6,13 , and one other study compared responses between sedentary and weight trained older adults. Studies showing solids are more satiating than liquids, that also measured appetitive serum markers. Four of the studies that found solids more satiating than liquids also measured hormones and other serum markers. the solid solid meal replacement bar Leidy et al had similar findings. The Cassady et al study, which measured perceived food form participants were told certain foods would remain liquid or solid once in the stomach , found higher glucose after what participants thought would be a liquid in their stomach 3. Studies showing food form has no effect on satiety. Four studies found that there was no difference in satiety between liquid or solid food forms. Three of these studies, Leidy b et al , Jones et al, and Akhaven et al involved a test food followed by an ad libitum meal in order to measure caloric intake. After one hour, participants were served pizza ad libitum. No significant difference was found in any of these studies with satiety ratings after consuming the liquid or solid preload. The teens in the Leidy b at al et al study who consumed the solid breakfast ate approximately kJ less compared to those that drank the shake kcal vs. Ranawana et al did not find a difference in satiety with solid vs. liquid forms, but in contrast to the above three studies, the researchers did not measure food intake at an ad libitum meal following the test food. Studies showing liquids are more satiating than solids. Interestingly, the two studies that found liquids to be more satiating than solids compared solid meals to soups. Clegg et al also tested a chunky version of the soup. In the Zhu b et al study, three hours after the soup test which was given at breakfast , participants were given an ad libitum pasta meal. The study also showed the liquid soup significantly increasing insulin 6. Most of these studies found that the whole form was more satiating and led to less caloric intake than the beverage test. The two studies that tested meal replacement bars to beverages, found bars to be more satiating. The effect of food form on satiety is a complex topic to research. Factors such as food aversions and preferences, cognitive attitudes towards food, time of day, intake of alcohol the previous day, insulin sensitivity, level of sleep the previous night, mental attitude on test day, level of exercise, genetic predisposition, and the palatability of the test food all effect food intake and satiety ratings. The timing and amount of preload, and time of ad libitum test meal also affect satiety and food intake. In women, higher trait anxiety was associated with a higher BMI, higher caloric intake, greater consumption of high-fat foods and persistent activation by fattening food cues after a meal. Specifically, low-anxiety women had reduced activation after eating in brain regions that regulate satiety, including the mOFC, amygdala, dorsal striatum, nucleus accumbens and insular cortex, but highly anxious women did not have reduced activation in these same regions. These findings were independent of BMI, and could implicate altered satiety processing as a risk factor for weight gain in highly anxious women. Importantly, even though anxious women tended to overeat during the experiment, their risk of excess weight gain over time appeared to be modified by their genetic background. As in previous studies 2 , 3 , anxiety was strongly related to having a higher BMI, but in our study this was specific to trait anxiety and only among women. We provide new information that genetic and familial factors modulate the relationship between anxiety and BMI. When female twins were analyzed as unique individuals by statistically accounting for twin relatedness, higher scores of trait anxiety were significantly associated with a higher BMI. However, when shared environmental and genetic traits between twins were controlled for by using within-pair comparisons, the relationships between trait anxiety and BMI disappeared. We also found relationships between anxiety and specific eating behaviors including total caloric and macronutrient intake that could support the hypothesis that anxiety contributes to weight gain and risk of obesity in genetically susceptible individuals. Women with high trait anxiety consumed more total kilocalories during the ad libitum buffet as well as a higher percentage of kilocalories from fat vs. carbohydrates, independent of BMI. Put another way, female twins who scored higher in trait anxiety ate more than their twin. These data provide strong evidence that trait anxiety independently increases food consumption. These findings suggest that anxious women increase food intake, but the extent that these extra kilocalories promote weight gain is influenced by genetic and familial factors. The relationship of anxiety to food intake has been a source of debate 41 — 43 particularly whether eating substantially relieves anxiety and thus serves a functional purpose. Experimentally-induced anxiety has been shown to increase food intake among individuals with a history of loss of control eating 44 or with high emotional eating scores 45 , but our data suggest that anxiety is related to increased caloric intake among generally healthy women as well. Findings from our nested case-control fMRI study provide evidence that women with high anxiety have altered brain response to food cues that could explain their greater caloric intake during the ad libitum buffet. The five regions of interest we examined were selected based on prior research establishing them as markers of satiety 12 ; in a state of hunger, these regions typically show robust activation by food images which decreases during post-meal satiety. High anxiety women did not reduce activation in these regions, providing evidence of a disruption in satiety perception. Importantly, these women, independent of BMI, also consumed more kilocalories at the post-scan buffet meal that objectively assessed satiety. The extra food consumption occurred without differences in self-reported appetite, further suggesting decoupling of eating behavior from hunger. These findings support theories that neural circuits regulating appetite are disrupted by chronic anxiety or stress in a manner that could promote obesity or eating disorders Alternately, heightened attentional functioning 47 or even improved visual detection among anxious women 48 might explain persistent post-meal responses to visual food cues, a question that deserves further study. The current findings emphasize potential differences between trait and state anxiety in relation to obesity risk. We show that the effects of state and trait anxiety on food consumption and macronutrient choice varied, and were significantly different by sex. In women, trait global anxiety was related to total caloric intake and food choice, whereas in men state current anxiety more strongly affected food choice. Moreover, as state anxiety is more closely related to stress, these results suggest that stress might also affect eating behaviors in men. These findings highlight the importance of investigating sex differences. A strength of our study is the use of a sample of twins, which allowed for examination of confounding of relationships between anxiety, food intake, and BMI by genetic and familial factors. However, due to the cross-sectional study design we cannot discern whether chronic anxiety contributed to the increased BMI among women or whether the altered eating and emotional regulation exhibited was a consequence of weight gain. Although obesity did not appear to explain the relationships seen in our study, previous studies have shown similar findings of persistent brain activation in response to high-calorie food cues in regions associated with food motivation and reward in obese individuals 49 , Our findings open the possibility that obesity and anxiety disrupt food cue perception and sensitivity to satiety cues in a similar fashion, either because they are causally related or as a result of shared mechanisms. This study cannot distinguish between these two possibilities. Another limitation was that we selected for relatively healthy individuals and also enrolled a high percentage of Caucasian subjects, therefore our results may not be generalizable to all populations. Additionally, we did not include an instrument capable of identifying clinical anxiety disorders among our sample, therefore, we cannot comment on the clinical severity of symptoms amongst the high anxiety women. We used BMI to relate anxiety to obesity; however, we recognize that measures of body composition or even waist circumference would have been more informative as to cardiometabolic risk. Future studies examining the role of anxiety in body fat distribution could be informative. Limited sample size 20 women and 20 men , though not uncommon in fMRI studies, could account for the high variability in our measures. We were unable to study the relation of state anxiety to fMRI findings in men due to limited numbers of men scoring high enough to reach clinical cutoffs in state anxiety. Clearly, sex and acute i. chronic anxiety each influence the ultimate effect of anxiety on eating behavior and should be taken into account in future studies. In conclusion, the current findings suggest that anxiety promotes caloric consumption and consumption of high-fat foods in women. We also provide evidence that anxiety alters brain responses to satiety such that the normal reduction in activation by high-calorie food cues induced by a meal 12 does not occur in highly anxious women, suggesting a disruption in neural circuitry that could promote overeating. Anxiety may be a risk factor for obesity, but we show this risk is likely limited to people with a genetic susceptibility to weight gain. Future longitudinal studies should examine a larger population to firmly establish whether anxiety and overeating are a risk factor for obesity in women. Interventions to promote a healthy weight in highly anxious women should test the utility of directly addressing anxiety, satiety and emotional eating habits as components of treatment.

Ad libitum caloric intake Total caloric and macronutrient intake were measured using an ad libitum buffet presented to each twin privately and containing a variety of foods appropriate for a midday meal. Food cue images Selection and validation of study images were completed in an independent study and have been described previously 12 , Imaging paradigm The imaging paradigm used in the current study has been described elsewhere Nested case-control analysis of anxiety and brain activation Cases and controls were defined based on STAI trait anxiety scores. Statistical Analysis Unless otherwise noted, analyses were performed with generalized estimating equations to account for relatedness within twins. Results Participant characteristics The final study sample included 55 participants 27 males, 28 females of which 41 were identified as an MZ twin and 14 as a DZ twin.

Figure 2. Figure 3. The hypothalamus, as it does for many aspects of homeostasis, integrates neural and hormonal signals for both the short- and long-term regulation of eating behavior and calorie intake. Hormones that influence these brain centers are synthesized in, and released from, peripheral tissues including the gut and fat cells adipocytes. These hormones can be categorically split into those that are anorexigenic, meaning that they suppress appetite, and those that are orexigenic, meaning that they stimulate appetite. The main hormones that regulate appetite and satiety are cholecystokinin, leptin, peptide YY, GLP-1, insulin, and ghrelin. Short-term control of food intake is regulated by plasma concentrations of nutrients including amino acids, glucose, and lipids. However, another significant influence on short-term regulation of food intake involves hormones released in the gastrointestinal GI tract. Gastrointestinal distention caused by a full stomach triggers the release of the hormone cholecystokinin CCK , which stimulates afferent fibers of the vagus nerve to send signals to the brain to suppress hunger. In addition, other hormones including GLP-1 and peptide YY PYY are secreted from the large and small intestines during and after eating. These hormones travel through the blood to the brain where they suppress hunger. Peptide YY also acts on the hypothalamus to inhibit gastric motility. Insulin released from the pancreas in response to eating also acts as a satiety hormone. Conversely, the hormone ghrelin is secreted from the stomach and pancreas when the stomach is empty; it can be thought of as a hunger hormone. Ghrelin is transmitted through the blood to the brain where it crosses the blood - brain barrier to act on the hunger areas in the lateral hypothalamus. After eating, ghrelin concentrations decrease. In addition to hormones secreted by the stomach and intestines to signal hunger or fullness, additional hormones are secreted by adipocytes fat cells that likewise act on the hunger and satiety centers in the hypothalamus. Because the level of these hormones depends on the amount of adipose tissue in the body, which changes slowly, these hormones are more involved in the long-term regulation of food intake. The hormone leptin is primarily secreted by fat cells and acts on receptors in the hypothalamus to decrease hunger. |

While protein still dominates, the larger minerals like calcium, potassium and sodium also play a role in the satiety equation. Brain Res Bull ; 14 6 : The effect of viscosity on ad libitum food intake. The plasma levels of glucose and insulin are the more considered biomarkers used as valuable information to connect the theory with the practical actions in the area of functional foods. Four studies found that, although solid test foods produced more satiety, intake of the ad libitum meal was not affected by food form of test food. |
Caloric intake and satiety -
Further, it is not clear whether any changes in hunger, fullness or later consumption that stem from differing ES are the result of a psychological or physiological response. The aims of this study were to manipulate ES for the same solid food on two occasions in order to compare participants' appetitive responses over a 4-h inter-meal period, to measure later consumption, and to assess whether any effect of ES on these measures was related to a physiological i.
total ghrelin response. There is a growing demand for convenience, as Americans spend more money on functional beverages. The Functional beverages category, consisting of energy drinks, sports drinks and nutraceutical drinks, grew by 7. Many factors influence our feelings of fullness and the amount of food we eat including our mental state, sleep patterns, physical activity, genetics, and hormone sensitivity.
Food form the physical state of the food: either in solid, semi-solid, or liquid also impacts how much we eat.
The effect of food form on satiety the physical feeling of fullness , satiation the end of desire to eat more after a meal, which can occur at any time after the onset of eating , and overall caloric intake is an important topic as nutritionists and food processors search for ways to help the public avoid over consuming calories.
The role of food form in satiety and caloric intake has been studied in various ways. One systematic review on the role of liquid vs. solid carbohydrates found that liquid carbohydrates are less satiating than solids, and food intake is not adjusted when calories are consumed in sugar-sweetened beverage form.
Chewing whole food has been thought to increase physiological responses, which lead to satiety. Whole foods are more slowly digested than liquids, so gastric emptying has been studied in relation to satiety.
Humans may have expectations that a food, which appears more solid, will be more satiating than a liquid. All 16 primary research papers in this review are randomized cross-over or partial cross-over studies. Two of the papers focus on older adults and one study was on adolescents. Solids were found to be more satiating than liquids in 11 of the studies.
Four of the studies found food form had no effect on satiety , and two studies found liquids were more satiating than solids. Most of the papers also tested additional measures such as food intake, the difference between lean and obese participants, and appetitive serum markers.
Of the 16 total papers reviewed, 11 studies found solid food to have a stronger effect on satiety than beverages. Of the nine that measured intake, five found that solid preloads led to less food intake at an ad libitum meal 7,8,11,13,14 and the four of the studies found that solid food form led to stronger feelings of satiety, but there was no effect on food intake.
Of the studies that found solids to be more satiating than liquids, measures other than food intake were investigated. Three looked at the difference in satiety response or caloric intake between lean and obese, 6,9,13 and four studies also looked at insulin, glucose and other serum markers.
Studies showing solids are more satiating that also looked at food intake. Nine studies that found solid foods are more satiating also measured food intake at an ad libitum meal following the test solid or liquid. Five studies found that a solid preload lead to less caloric intake 7,8,11,13,14 , and four studies found that food form of preload had no effect on food intake of a test meal.
Studies showing solids are more satiating and also found solids decrease food intake. The five studies that found solids to be more satiating and found a solid preload to be more satiating than a beverage preload were Cassady et al , Yoemans et al , Flood-Obbagy et al , Houchins et al and Hogenkamp a et al.
In all studies except Hogenkamp a et al , participants were given a test food of either a solid or liquid, asked about their feeling of satiety then, after a set period of time, given an ad libitum as much as you can eat meal. The Hogenkamp a et al study tested intake on the actual test foods no on a follow up meal after a preload.
Cassady et al and Houchins et al offered macaroni and cheese, while Yoemans et al offered pasta and ice cream and Flood-Obbagy et al served cheese tortellini with tomato sauce. Total intake of the meal was measured, and in these four tests, researchers found that those who consumed a solid test food consumed less of the ad libitum meal.
Hogenkamp a et al also found that participants consumed more with the liquid test, even though the methods of their experiment differed. The 52 healthy adults in Cassady et al, were exposed to four different preload foods. Yoemans et al tested thin and thickened energy drinks on 48 healthy adults over multiple days.
In a study by Hogenkamp a et al, the differences in expected satiety and intake after repeated consumption of liquids and semi solid foods were tested on 53 healthy adults. All five studies above, which showed that solids were significantly more satiating than liquids and led to less intake, were relatively small, ranging from the largest of 58 in Flood-Obbagy et al to 34 in the Houchins et al study and involved adults of normal BMI, except for the Houchins et al study, which compared the results from 15 lean and 19 obese adults.
Studies that showed solids are more satiating but food form of preload had no effect on intake. Four studies found that, although solid test foods produced more satiety, intake of the ad libitum meal was not affected by food form of test food.
In Mattes et al, the test food was apples in the whole, semi-solid applesauce , and liquid juice form. The Apolzan et al study tested the difference in solid meal replacement bars vs. liquid meal replacement beverages of the same nutritional content. The Hogenkamp b et al study tested learned satiety over time with a high energy HE vs.
low energy LE in beverage or semi-solid form over several consecutive days, followed by an ad libitum buffet lunch. Zhu a et al studied the difference a standard viscosity custard and high viscosity pudding meal.
custard Studies showing solids are more satiating than liquids, that compared responses between lean and obese. Of the studies that found solids to be more satiating than liquids, two studies compared lean and obese adults 6,13 , and one other study compared responses between sedentary and weight trained older adults.
Studies showing solids are more satiating than liquids, that also measured appetitive serum markers. Four of the studies that found solids more satiating than liquids also measured hormones and other serum markers. the solid solid meal replacement bar Leidy et al had similar findings.
The Cassady et al study, which measured perceived food form participants were told certain foods would remain liquid or solid once in the stomach , found higher glucose after what participants thought would be a liquid in their stomach 3. Studies showing food form has no effect on satiety.
Four studies found that there was no difference in satiety between liquid or solid food forms. Three of these studies, Leidy b et al , Jones et al, and Akhaven et al involved a test food followed by an ad libitum meal in order to measure caloric intake.
After one hour, participants were served pizza ad libitum. No significant difference was found in any of these studies with satiety ratings after consuming the liquid or solid preload.
The teens in the Leidy b at al et al study who consumed the solid breakfast ate approximately kJ less compared to those that drank the shake kcal vs. Ranawana et al did not find a difference in satiety with solid vs.
liquid forms, but in contrast to the above three studies, the researchers did not measure food intake at an ad libitum meal following the test food. Studies showing liquids are more satiating than solids. Interestingly, the two studies that found liquids to be more satiating than solids compared solid meals to soups.
Clegg et al also tested a chunky version of the soup. In the Zhu b et al study, three hours after the soup test which was given at breakfast , participants were given an ad libitum pasta meal.
The study also showed the liquid soup significantly increasing insulin 6. Most of these studies found that the whole form was more satiating and led to less caloric intake than the beverage test. The two studies that tested meal replacement bars to beverages, found bars to be more satiating.
The effect of food form on satiety is a complex topic to research. There was no evidence for any significant differences being the result of changes in total ghrelin. Overall, the data suggest that ES for a solid food can be manipulated and that, when given at breakfast, having a higher ES for a meal reduces lunchtime and whole day caloric consumption.
