Recent data implicate impulsivity as a personality trait associated with obesity, binge eating and restrained eating. However, impulsivity is recognised as having multiple dimensions, and it remains unclear which aspects of impulsive behaviour best predict disordered eating. To try and elucidate further the relationship between impulsivity and eating behaviour, 147 women completed a behavioural measure...
The present study examined the independent and interactive association between smoking, gender, dietary restraint and the relative reinforcing value of snack food in a university sample. Four hundred and three introductory psychology students completed questionnaires assessing age, gender, BMI, hunger, smoking status, nicotine dependence, dietary restraint, hedonic ratings and the relative reinforcing...
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)...
The study tests existing evidence on the paradoxical effects of exposure to a forbidden snack. Sixty-eight females were assigned randomly to one of two conditions: a temptation group, who were given the instruction to abstain from a favourite snack for 24h while being exposed to it, or a control group, who were given no specific instructions. A further distinction was made between high-restraint/high-disinhibition...
The present study investigated the effects of exposure to a food cue on the self-reported importance of dieting in those with low, medium, and high levels of dietary restraint. The results indicated that exposure to a food cue bolstered dieting-related goals in those who were low in dietary restraint but had no effect on the importance of dieting-related goals for those with medium or high levels...
This paper (i) explores the proposition that body weight is associated with large portion sizes and (ii) introduces a new technique for measuring everyday portion size. In our paradigm, the participant is shown a picture of a food portion and is asked to indicate whether it is larger or smaller than their usual portion. After responding to a range of different portions an estimate of everyday portion...
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 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...
