As the proportion of the UK population who may be considered overweight or obese is increasing, questions about the impact of foods and food constituents upon appetite and satiety become increasingly important. Briefly reviews some of the literature on the effects of dietary fibre (or, more correctly, non‐starch polysaccharides) on satiety. A number of experimental approaches have been used to investigate this issue and, according to the mode of administration of dietary fibre used, a variable outcome on satiety has been demonstrated. However, the evidence overall is quite strongly in favour of an enhancement of satiety with dietary fibre. Unfortunately, clinical trials of the effects of dietary fibre have revealed only modest improvements in weight loss and further work is needed in order to target those individuals who demonstrate the greatest response.

This review aims to document the influence of low glycaemic index (LGI) and low glycaemic load (LGL) foods over food satiety, their utilisation in clinical practice, and their importance in the prevention and control of diseases such as obesity, diabetes and cardiopathies. It also aims to discuss the inclusion of glycaemic index (GI) information in food labels as an important tool for the consumer who wishes to make healthier choices.

An extensive literature search was conducted in the Web of Science, Pub Med and Medline databases, as well as in reference lists from the scientific articles retrieved in the search.

Most of the articles presented similar results regarding the substitution of high glycaemic index (HGI) foods for low GI ones. In diabetics there was an improvement in the glycaemic and lipid profiles control, and in the obese, weight reduction and reduced cardiovascular complications risk were observed. Foods with higher satiety potential were identified as those with lower GIs, which reduce appetite, cause less glycaemic oscillations in diabetics, and lower caloric intake in the obese.

This revision evidenced the benefits of LGI foods over satiety and palatability, and discussed their effect in the treatment of chronic non‐transmissible diseases such as obesity and diabetes.

Previous studies have reported that dietary fibers such as polydextrose and maltodextrin can reduce food intake; however, the studies on the differences of this effect are insufficient. The purpose of this paper is to compare the effects of dietary fibers maltodextrin and polydextrose on alterations of short-term satiety, energy intake and postprandial blood glucose in healthy females.

This study was designed as a randomized, crossover and double blind research. For this purpose, 21 healthy females consumed a milkshake containing 0 g (control), 15 g polydextrose (PDX) and 15 g maltodextrin (MDX), and an ad libitum lunch meal was served 150 min later. Subjective appetite scores (hunger, satiety, prospective food consumption and desire to eat) were measured using a visual analog scale. Appetite scores and blood glucose were measured before preload and once per 15 min after milkshake consumption.

Visual analog scale scores showed that PDX had an improved effect on satiety and hunger feelings. Compared to the control, dietary fiber increased the Area Under Curve (AUC) scores of satiety (p < 0.001) and decreased the AUC scores of hunger (p < 0.001), prospective food consumption (p < 0.001) and desire to eat (p < 0.001). Energy intake during ad libitum meal was significantly lower in PDX (Control: 862 (54.3) Kcal versus PDX: 679 (35.4) Kcal and MDX: 780 (49.3) Kcal. Moreover, the blood glucose levels were significantly lower in MDX.

This study conducted with healthy females demonstrated that PDX was more effective in inducing satiety during subsequent food intake, and that postprandial blood glucose were within more healthy levels in MDX.

Eating and drinking temporarily suppress the desire to eat and/or the desire to drink. These satiating effects are learned responses to complex patterns of stimulation from available foods and drinks and the external and internal environments. Considers the possible roles of physiological actions of ingested foods and beverages in the signals from the body which contribute to the sense of repletion, the dulling of hunger and the quenching of thirst.

Assesses the effect of fat substitutes on satiety and subsequent food intake in men; 50 per cent of fat in pork sausages was replaced by natural fat substitutes ‐ Avicel, Tapiocaline and Simplesse. Results showed that high‐energy fat breakfasts comprising full‐fat sausages led to delayed satiety compared with high‐energy CHO breakfasts. There were no differences between hunger and satiety ratings nor energy and fat intakes following different fatsubstituted breakfasts on the test day and the following day. The deficit in energy between high‐energy and reduced‐energy breakfasts was maintained throughout the test day. Consumption of one reduced‐fat meal resulted in a significant reduction of energy intake, which was not compensated for on the test day or on the following day.

The purpose of the paper is to determine the effects of a hypocaloric diet with a low-glycaemic index (GI) on weight loss and postprandial blood glucose and assess both the satiety and palatability of the diet.

A clinical trial was conducted with ten women (mean age: 38.8±11.3 years; body mass index: 27.2±3.5 kg/m2) submitted to a hypocaloric diet, assessments were performed at baseline and after seven days of treatment.

Significant reductions were found in body weight (1.1±0.7 kg; p=0.001), triccipital skinfold (2.87±3.24 mm; p=0.021) and waist circumference (3.6±4.8 cm; p=0.041). Mean fasting and postprandial blood glucose values were 88.7±6.1 mg/dL and 91.6±9.6 mg/dL, respectively. Responses regarding satiety and palatability of the low-GI diet were predominantly “extremely satisfied” and “I liked it very much,” respectively, for all meals and throughout all seven days of the study.

The present study demonstrated the benefits of a low-GI diet with regard to weight loss, blood glucose control and satiety. The diet proved to be palatable, which could favor compliance with long-term treatment.

Duodenal action of rapidly digested carbohydrate can induce an intense satiation shortly after the meal, which conditions down the volume of food eaten in the later part of the meal. In contrast, after a meal rich in spreading fat, separation of fat above the aqueous contents of the stomach is liable to delay the fat’s emptying and hence its contact with satiety receptors in the small intestine; eaters are therefore unlikely to learn to eat less of a menu rich in separated fat. Yet the delayed emptying may prolong the period of digestion and absorption of separated fat beyond that for the same amount of fat emulsified or bound in the aqueous phase. Hence, separating fat might help to delay better the rise of appetite for the next meal several hours later. These ideas explain some of the diversity of claims about satiation from fats in foods. Observes how individuals learn from the post‐ingestional effects on appetite of variants of the foods they choose routinely.

This paper aims to investigate the satiety properties of a fish protein hydrolysate (blue whiting muscle hydrolysate, BWMH). Protein consumption is associated with higher satiety, protein being considered as the more satiating macronutrient. This property is extensively investigated in regard to weight management.

Fifteen overweight women were included in a crossover design study. Subjects consumed 1 g of BWMH or placebo twice daily and sensations associated with satiety were recorded every day.

Significant differences, in favour of BWMH, were highlighted on the desire to eat something sweet at T90 min (p < 0.05) and on plasma glucose at T270 min (p < 0.05).

This study demonstrates effect of BWMH on appetite. Indeed promising data were reported in favour of the test product, in particular on the desire to eat something sweet and on glucose levels. Some additional investigations will be necessary to support these data and those observed in in vitro and in vivo models.

After promising pre-clinical data, this study is a first investigation of health benefits of BWMH supplementation in humans.

Excessive fat intake is a problem in the UK and other European countries. Looks at the relationship between dietary fat and body fat and the body′s physiological responses to fatty food. Discusses experimental studies on fat and satiety and high fat hyperphagia.

The purpose of this paper is to prepare alginate‐pectin‐starch containing matrices expanded by the generation of carbon dioxide, from carbonates when in contact with acids, characterise their structure in vitro and to assess their capacity to provide satiety in vivo.

For in vitro characterisation, carbon dioxide expanded polysaccharide matrices (rafts) were prepared in HCl and their structural strength was measured in terms of their capacity to resist breakage in a model test system. For in vivo trials, 12 healthy volunteers (mixed sex, aged 25‐55) were recruited to take part in the three‐part trial. Each part lasted for one week where volunteers consumed polysaccharides (in 50 ml water) with or without rafting salts (carbonates), or water (as a control). Effects on satiety, reduction of food intake and any change to body weight were evaluated with the volunteers.

The in vitro results showed that aqueous solution/dispersions (50 ml) of alginate‐pectin‐starch matrices produced rafts in hydrochloric acid (pH < 2), where increasing the ratio of carbonates to polysaccharides (range from 0.25:1 to 1.5:1, w/w) provided increased floatation capability but reducing gel strength. These rafts were stable for over 24 h at room temperature within 0.05‐0.5 M HCl. For in vivo “satiety” studies, when volunteers consumed (daily) aliquots of the polysaccharide mixture plus flavour and sweetener without carbonates 2.5 h after lunch, they felt the onset of hunger on average 186 ± 68 min after consumption of the polysaccharides. This was not significantly different from a water only control (onset of hunger at 165 ± 47 min). When polysaccharides plus flavour sweetener and carbonates were consumed, however, volunteers reported feeling the onset of hunger at 224 ± 62 min on average after consumption which was significantly different from the water control (p < 0.001), or the polysaccharides without carbonates (p < 0.01). When consuming the polysaccharide rafting format, half of the volunteers reported a reduction in size of their evening meal.

These data indicate that the alginate‐pectin‐starch combination with carbonate salts in a “gastric rafting format” provide a potential approach in the management of body weight and obesity.
