Functional neuroimaging was employed to study 10 obese and 10 lean healthy young right-handed women, divided equally into binge and non-binge eaters. Subjects were presented with visual and auditory stimuli of binge type foods, non-binge type foods, and non-food stimuli in the fMRI scanner. Brain areas activated by both the visual and auditory stimuli across all individual subjects within a particular...
In clinical practice, obese patients report stress as a primary trigger for binge eating. However, the biological mechanism underlying this relationship is poorly understood. This paper presents, a theoretical overview of how cortisol secretion, a major component of the stress response, could play a role in binge eating, given that exogenous glucocorticoids can lead to obesity by increasing food intake...
Restrained eaters tend to increase and unrestrained eaters to decrease their food intake when stressed. This relationship, though robust, does not appear to be caused by restrained eating or by stress per se. For restraint, evidence indicates that none of the common operationalizations of restraint can account for restraint-related effects that have been examined to date. It is therefore unlikely...
While identity has been a dominant topic in research on food choice, literature on identity in consumers' everyday life is scarce. In this article we draw on insights from discursive psychology to demonstrate how members of an online forum on food pleasure handle the hedonic appreciation of food in everyday interaction. We examined 40 discussions consisting of 1715 e-mails related to culinary topics...
Cumulative responses are important for the study of ingestive behavior. The total amounts consumed at several time points after experimental or control treatments are often analyzed using a mixed-model analysis of variance. The method used by some investigators to calculate the significance of this difference is invalid and may lead to serious errors of inference. Direct analysis of cumulative data...
To determine if the lunchtime food provided to schoolchildren adheres to nutritional standards and to examine the influence of children's food choice on nutrient intake at lunchtime.Seventy-four children aged 11–12 years were recruited from three secondary schools. The school populations spanned a spectrum of socio-economic deprivation. Lunchtime food and nutrient intake was assessed over a 5 day...
The present study investigated the effects of hunger and visuo-spatial interference on imagery-induced food cravings. Forty-two women were randomly assigned to a hungry (no food for prior 4h) or not hungry condition. Participants were asked to form and maintain images of desired foods while looking at a blank computer screen (control condition) or performing a task designed to load the visuo-spatial...
The influence of the composition of foods, their macronutrient contents and the dietary energy densities on intake, were investigated by analyzing 7-day diet diary reports from 669 free-living normal adult humans who adequately reported intake. The analyses revealed subtle but small macronutrient specific relationships with intake. Dietary energy density, however, was found to have large reliable...
Intermittent excessive behaviors (IEB) characterize a variety human disorders including binge eating, drug abuse, alcoholism, aberrant sexual conduct, and compulsive gambling. Clinical co-morbidity exists among IEB, and limited treatment options are available. The use of behavioral models of bingeing and other feeding protocols is beginning to clarify neural similarities and differences that exist...
The reinforcing value of food, measured by how hard someone is willing to work to obtain food, is influenced by food palatability, food deprivation and food variety, and may be a more powerful determinant of food intake than hedonics or liking. The reinforcing value of food is mediated in part by dopaminergic activity. Genotypes that influence dopamine transport and the density of dopamine D2 receptors...
This paper explores whether breast-feeding, mediated by lower maternal use of controlling strategies, predicts more positive mealtime interactions between mothers and their 1 year old infants. Eighty-seven women completed questionnaires regarding breast-feeding, assessing their control over child feeding and mealtime negativity at 1 year of infant age. Seventy-four of these women were also observed...
The present study investigated whether the most preferred balance between sweet and sour taste of children (n=50, 9.2±0.9 yrs of age) are related to their consumption of fruit. Taste preferences were measured with a rank-by-elimination procedure with seven sweet orangeades that differed in added citric acid (i.e. 0.009−0.065M). Fruit consumption was assessed with a questionnaire that was completed...
Previous research has demonstrated that individuals' beliefs about the disgusting properties of foods play a central role in predicting willingness to eat novel foods of either animal or nonanimal origin (Martins & Pliner, in press). The present study aimed to identify what characteristics of foods make individuals perceive them as disgusting. In this study, participants read a set of scenarios...
The current obesity pandemic imposes a major global disease burden. However, sustained weight loss of between 5 and 10% in the obese confers marked health benefits. Currently available pharmacotherapies, orlistat and sibutramine, can induce weight loss of between 5 and 10% over 2 years or more. However, in these trials, drug induced weight loss tends to be only 2–4kg greater than that produced by...
The universal eating monitor (UEM) of Kissileff for laboratory measurement of food intake was modified and used with a newly developed special software to compute cumulative intake data. To explore the measurement precision of the UEM an investigation of test–retest-reliability of food intake parameters was conducted. The intake characteristics of 61 normalweight males and females were measured repeatedly...
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...
