Recent research has drawn attention to the role of past behaviour and habit in the overall structure of consumer behaviour. We argue that in cross-sectional data past behaviour and habit must be confounded with present beliefs and attitudes when the behaviour in question has been enacted numerous times before. To disentangle the effects, longitudinal data were collected from a large panel of Norwegian...
Cluster-analytic studies of clinical populations of eating disordered women who binge eat have yielded two subtypes – pure dietary restraint and mixed dietary restraint-negative affect – consistent with etiologic and maintenance models of binge eating. This study aimed to replicate this subtyping scheme in university women. The scores of 623 undergrad females on the TFEQ-restraint and BDI scales were...
The notion that preferences for flavors paired with various nutrients can be attributed simply to their energy content (“flavor-calorie learning”) is belied by variation in nutrient reinforcing potency. Fructose, fat and ethanol, all regarded as powerful contributors to food and fluid preferences, are less potent than glucose when their orosensory effects are bypassed. Conditioning studies in animals...
The aim of this study was to explore associations between chronotype and the Three-Factor-Eating-Questionnaire. We found a positive association between morningness and dietary restraint and negative correlations between morningness and disinhibition and perceived hunger. Further, there was an association between morningness and flexible control. BMI tended to be negatively associated with morningness...
The effects of exposure to televised thin and average size models on body dissatisfaction and actual food intake were examined. Normal weight female students (N=104) were exposed to a 30-min movie clip featuring beautiful girls. Half of them viewed the movie clip in normal screen size (4:3) and the other half viewed the same movie clip in broad screen size (16:9), in which the body size of the actresses...
Overweight is increasing rapidly in children, compelling researchers to seek for determinants of adverse food intake. In a previous experiment it was found that manipulating the restriction of attractive snacks increased the desirability and intake of these snacks. In the present study, we tested whether this paradoxical restricting effect is also seen in relatively less attractive but healthy food,...
This study explored whether parents who purchase more fruit/vegetables have preschool-aged children who are able to identify fruit/vegetables and in turn are more likely to consume them. Sixty-two parent–child pairs were recruited during a 4-month period. The data collection included a child interview, a parent/guardian interview, a fruit/vegetable taste test for children, and a month-long food-receipt...
The aims of this study were to compare the effects of weight-loss diets of different macronutrient compositions on weight and health-related quality of life (HRQOL), and to examine the relationship between changes in HRQOL parameters and weight loss during weight-loss programs in obese adolescents.Seventy one adolescents (12–18 years, BMI>95th percentile) were randomly allocated to one of three...
The leaves of the khat plant (Catha edulis) are chewed for their pleasurable effects. Chewing releases cathinone which may decrease appetite through an unknown mechanism. Levels of the peptide ghrelin increase with hunger and decrease immediately post-prandially, while peptide YY is released following a meal. We hypothesised that the anorexigenic effects of khat may be mediated through changes in...
We analyzed the antecedents of adolescents’ influence in family meal decisions, with a focus on fish. The results are based on a representative sample of about 1000 Norwegian schoolchildren between the age of 13 and 18 (adolescents). Fish is a mainstay of Norwegian diets ensuring high familiarity and divergent preferences between persons and among household members. Structural equation modelling was...
