“…In addition to the primary outcome of changes in RRV of food, we also examined DD. Individuals with greater rates of DD are more likely to have obesity and consume more food in ad libitum eating tasks . Our data support these findings, with adolescents with obesity having greater rates of DD for small and medium rewards compared with adolescents with a healthy weight or overweight.…”

Objective The purpose of this study was to examine the impact of daily exposure to a low-energy-dense (LED) or a high-energy-dense (HED) snack food on its reinforcing value (RRV) in adolescents with healthy weight, overweight, or obesity. Methods We used a parallel-group, randomized trial to assess RRV of LED or HED snack food at baseline and again after exposure to that snack food daily for two weeks in 77 adolescents, aged 13 – 17 years. Information on eating-related subject characteristics was also collected at baseline. Results After two weeks of daily exposure, the RRV of the snack foods was significantly reduced in all participants, regardless of energy density or participant weight status. Among individuals who were high in dietary restraint only, those randomized to LED food found their snack food less reinforcing at baseline than those who were randomized to HED food. Baseline eating-related variables also differed as a function of weight status. Conclusions Daily exposure to snack food in adolescents reduces the RRV of that food regardless of snack food energy density or weight status of the adolescent. This finding differs from adults, suggesting that increases in RRV of HED food after repeated exposure may develop after adolescence.

“…Hedonic hunger alone may be insufficient to predict intake, but could promote overconsumption when it exists in combination with other individual characteristics, such as impulsivity . For example, among overweight and obese adult females, individuals with greater hedonic hunger consumed more palatable food in a sham taste test following a standardized pre‐load meal, but only for those also high in impulsivity (as measured by delay discounting) .…”

SummaryIntroductionThe term ‘hedonic hunger’ refers to one's preoccupation with and desire to consume foods for the purposes of pleasure and in the absence of physical hunger. The Power of Food Scale (PFS) was developed as a quantitative measure of this construct in 2009. Since then, over 50 published studies have used the PFS to predict appetite‐related outcomes including neural, cognitive, behavioural, anthropometric and clinical measures.ObjectiveThis narrative review evaluates how closely the PFS captures the construct it was originally presumed to assess and to more clearly define hedonic hunger itself.MethodsThe measure's relationship to four domains is reviewed and summarized: motivation to consume palatable foods; level of actual consumption of such foods; body mass; and subjective loss‐of‐control over one's eating behaviour. Findings are synthesized to generate a more accurate understanding of what the PFS measures and how it may relate to the broader definition of hedonic hunger.ResultsResults suggest that the PFS is closely related to motivation to consume palatable foods and, in extreme cases, occurrence of loss‐of‐control eating episodes. PFS scores are not consistently predictive of amount of food consumed or body mass.ConclusionsImplications of these findings are discussed in the context of behavioural health, and avenues for further inquiry are identified.

“…The lower the IP values, the less an individual is willing to wait for the reward, indicating a reduced ability to delay gratification. Discounting of the future on both money and food-based tasks has been related to over eating and obesity, albeit inconsistently [2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

Delay discounting of financial rewards has been related to overeating and obesity. Neuropsychological evidence supports a dual-system account of both discounting and overeating behaviour where the degree of impulsive decision making is determined by the relative strength of reward desire and executive control. A dual-parameter model of discounting behaviour is consistent with this theory. In this study, the fit of the commonly used one-parameter model was compared to a new dual-parameter model for the first time in a sample of adults with wide ranging BMI. Delay discounting data from 79 males and females (males=26) across a wide age (M=28.44years (SD=8.81)) and BMI range (M=25.42 (SD=5.16)) was analysed. A dual-parameter model (saturating-hyperbolic; Doya, [Doya (2008) ]) was applied to the data and compared on model fit indices to the single-parameter model. Discounting was significantly greater in the overweight/obese participants using both models, however, the two parameter model showed a superior fit to data (p<0.0001). The two parameters were shown to be related yet distinct measures consistent with a dual-system account of inter-temporal choice behaviour. The dual-parameter model showed superior fit to data and the two parameters were shown to be related yet distinct indices sensitive to differences between weight groups. Findings are discussed in terms of the impulsive reward and executive control systems that contribute to unhealthy food choice and within the context of obesity related research.
