This study investigated the effects of food deprivation on the body image in female restrained and unrestrained eaters. Twenty female restrained eaters and 20 female unrestrained eaters were asked to identify their current and their ideal body shape by choosing them from a sample of nine female silhouettes. This test was conducted under three deprivational conditions: hungry, thirsty and non-deprived...
The first 30 years of Columbia's Appetitive Seminar were celebrated by speakers extrapolating from the past to the future for six areas of research on appetite. This editorial introduces reviews of three of the selected topics and briefly summarizes the other three presentations-on the sensing of glucose utilization, gastrointestinal controls of satiety and mechanisms of learning and conditioning.
Satiety ratings are often made using VAS or simple category scales. In order to establish a simple, more quantitative technique to index perceived hunger and/or fullness, research was undertaken to develop and test a labeled magnitude scale of satiety.Thirty-seven subjects rated the semantic meaning of 47 phrases describing different levels of hunger/fullness using magnitude estimation. Eleven phrases...
Beverages are frequently consumed with meals, but their influence on meal energy intake is not understood. We hypothesized that differences in the energy, nutrient content, and sensory properties of beverages consumed with a meal would affect intake. Forty-four women ate lunch in the laboratory once a week for 6 weeks. Lunch was consumed ad libitum, and was served with one of five beverages that were...
The satiety values of six breakfast items commonly consumed in India were determined on the basis of area under the curve. A repeated measures design was used wherein energy intake, hunger, and satiety scores were assessed for one rice-based, three wheat-based and a rice–pulse fermented preparation, using white bread as the reference. Subjects were provided equi-caloric portions of the six breakfast...
Body-weight management requires a multi-factorial approach. Recent findings suggest that an elevated protein intake seems to play such a key role in body-weight management, through (i) increased satiety related to increased diet-induced thermogenesis, (ii) its effect on thermogenesis, (iii) body composition, and (iv) decreased energy-efficiency. Supported by these mechanisms a relatively larger weight...
This study tested if: (1) a preload of mycoprotein and tofu consumed before a lunch meal have a greater effect on satiety when compared to a chicken preload, (2) the mycoprotein and tofu preloads, compared to chicken, are not associated with compensation or eating more food at a subsequent dinner meal. These hypotheses were tested in a controlled laboratory study using universal eating monitors to...
We determined taste recognition thresholds for six compounds (sucrose, fructose, sodium chloride, quinine sulphate, PROP and liquorice) in fasting students and, in the same subjects, after a meal. The testing procedure was the staircase-method in blind conditions. Although taste sensitivity may vary with hormonal status, our results did not show any significant difference in taste recognition thresholds...
The present study tested whether foods categorized as meals reduce subsequent intake more than isocaloric foods categorized as snacks. The study was repeated three times with variations. In each variation we manipulated whether subjects received meal or snack foods in an isocaloric load. In Variation 1, subjects consumed less following a load of meal foods than snacks. Variation 2 found this effect...
Salivary responses habituate to repeated presentations of food cues, and these responses recover when new food stimuli are presented. Research suggests that within-session changes in motivated responding for food may also habituate, and motivated responding may, therefore, recover when new foods are presented. The purpose of this study was to evaluate similarities in the pattern of salivation and...
Improving children's abilities to recognize when they are full is one strategy to prevent overweight, but currently, there are few validated instruments to assist this process. In the present study, we developed and tested the potential of an analog scaling device for quantifying sensations such as fullness in 4–5 year old children. The device was a picture of a doll with a rectangular stomach over...
Should future nutritional recommendations for the general population take into account the notion of glycaemic index (GI)? This question is all the more legitimate as the glycaemic response to foods seems to be a factor that affects satiety and could therefore affect food intake. The aim of this review was to evaluate whether altering the glycaemic response per se can modulate satiety and to assess...
Consuming soup can enhance satiety and reduce energy intake. Little is known about the influence on energy intake and satiety of varying the form of soup by altering the blending of ingredients. We tested the effects on meal intake of consuming different forms of soup as a preload: broth and vegetables served separately, chunky vegetable soup, chunky-pureed vegetable soup, or pureed vegetable soup...
l-Phenylalanine (Phe), is a potent releaser of the satiety hormone, cholecystokinin (CCK) and previous studies, conducted primarily in men, show that ingestion of Phe reduces energy intake. The objective of the current study was to test the effects of Phe on energy intake in overweight and obese women. Subjects (n=32) received three treatments (high-dose (10g Phe), low-dose (5g Phe and 5g glucose)...
Long chain omega-3 fatty acids (LC n-3 FA) are considered nutritional factors with a potential to modulate food intake. Thus, the aim of the current study was to determine whether appetite could be affected by LC n-3 FA when included in a calorie-restricted diet to treat overweight or obesity.Appetite was explored in volunteers (31±5 years; BMI: 28.3±1.5kg/m 2 ) during the last 2 weeks of...
This study assessed the effect of exercise timing relative to meal consumption on appetite and its hormonal regulators (i.e., PYY 3–36 , ghrelin and leptin) in moderately active young men. Twelve men performed three trials in a random order: (1) meal consumption, (2) exercise 2h after a meal, (3) exercise 1h before a meal. The test meal provided 16.5kcalkg −1 with 70% fat, 26% carbohydrate...
This study aimed to characterise meal patterns and satiety effects of diets that are high in protein but differ in protein source. Using a computerised automatic recording system, meal pattern behaviour was recorded continuously for 7 days in mice fed single (whey, soy or gluten) or different combined protein diets. Overall, average energy intake was significantly lower in mice fed a whey protein...
Aim: To compare the effects of whey versus whey without glycomacropeptide (GMP) in a high and a normal amount of protein in a breakfast custard on satiety and energy intake (EI), taking concentrations of amino acids (AA), glucose, insulin, glucagon-like peptide 1 (GLP-1) and ghrelin into account. Methods: Twenty-five healthy subjects (mean±S.E.M., BMI: 23.9±0.3kg/m 2 ; age: 22±1 years) received...
Consuming whole fruit reduces ratings of satiety more than fruit juice, but little is known about the effects of different forms of fruit on subsequent energy intake. This study tested how consuming preloads of apples in different forms prior to a meal (apple, applesauce, and apple juice with and without added fiber) influences satiety and energy intake at meal. Preloads were matched for weight, energy...
Protein is considered to be more satiating than carbohydrate, quantified by energy adjustment and subjective appetite. However, the effect of increasing protein content upon short-term energy adjustment in beverage contexts is unclear. This study used a repeated-measures, cross-over design. 28 male volunteers (18–35 years) ate a standard breakfast in the laboratory and 210min later consumed one of...
