OBJECTIVE The colonic microbiota ferment dietary fibres, producing short chain fatty acids. Recent evidence suggests that the short chain fatty acid propionate may play an important role in appetite regulation. We hypothesised that colonic delivery of propionate would increase peptide YY (PYY) and glucagon like peptide-1 (GLP-1) secretion in humans, and(More)
The efficacy of exercise to promote weight loss could potentially be undermined by its influence on explicit or implicit processes of liking and wanting for food which in turn alter food preference. The present study was designed to examine hedonic and homeostatic mechanisms involved in the acute effects of exercise on food intake. 24 healthy female(More)

Eating is an action open to awareness by the individual; however, it cannot be claimed that processes that control the expression of eating habits are necessarily explicit. This distinction between implicit and explicit processes may enhance understanding of the expression of food reward (particularly the concepts of liking and wanting [Berridge, K. C., &(More)
PURPOSE The present research compared a self-report measure of usual eating behaviors with two laboratory-based behavioral measures of food reward and food preference. METHODS Eating behaviors were measured among 233 working adults. A self-report measure was the Three Factor Eating Questionnaire (TFEQ) Restraint, Disinhibition and Hunger subscales.(More)
The present study used a measure of trait binge eating (Binge Eating Scale; BES) to examine its association with behavioural markers of appetite and food reward. Non-obese female participants consumed a preload before freely selecting and consuming from a test meal. Subjective hunger and hedonic measures of explicit liking and implicit wanting for food were(More)
BACKGROUND Recent frameworks for understanding food rewards recognize the role of separable affective and motivational processes (liking and wanting) in driving human eating behavior. Separate assessments of liking and wanting may aid in understanding the complex eating-related behaviors seen in anorexia nervosa (AN). OBJECTIVE The aim of this study was(More)
INTRODUCTION We examined the impact of a 24 hour complete fast (vs. fed state) on two measures of food reward: 1) 'wanting', as measured by response to food images and by the relative-reinforcing value of food (RRV), and 2) 'liking', as measured by response to food images and the hedonic evaluation of foods consumed. METHODS Utilizing a randomized(More)
Dietary restriction often fails in the face of tempting and palatable foods; however there is evidence that exposure to diet-congruent cues, such as foods associated with 'slimming' may facilitate control over food intake. The present study examined the effect of exposure to a diet-congruent food on subsequent energy intake in active dieters. Using a(More)
The main objectives of our study were (1) to compare several direct and indirect measures of liking and wanting for food and thereby (2) investigating the transfer effect of sensory specific satiety (SSS) for sweet and savory taste to other foods. We used a cross-over design whereby 61 healthy, unrestrained subjects (19M/42F), with a mean age of 21.9 (SD(More)
