Background: Eating in the absence of hunger (EAH) measures intake of highly palatable, highly processed foods when sated, and may reflect food reward sensitivity. However, it is unknown whether EAH occurs in the presence of low-processed, nutrient-dense foods, and the relationship of self-reported food reward sensitivity with EAH during pregnancy has not been examined.Objective: This study tested whether EAH differs for highly-processed (HP) versus low-processed (LP) foods in pregnant women and examined relationships of EAH with self-reported food reward sensitivity and impulsivity.Design: Women in their 2nd trimester (n=46) enrolled in a counterbalanced crossover study in which they completed two EAH conditions following a standardized meal. Participants completed the Power of Food Scale (PFS), the modified Yale Food Addiction Scale (m-YFAS), and the Barratt Impulsiveness Scale (BIS). EAH energy intake (EAH-kcal) and proportion consumed (EAH-%) was measured overall and separately for sweet and savory test foods. Results: EAH-% was similar across conditions (16.3% ± 1.1% HP versus 17.9% ± 1.2% LP, P = 0.74), resulting in 347.7 ± 49.0 kcal greater energy intake in the HP versus LP condition (P < 0.001). PFS was not significantly associated with EAH; m-YFAS was positively associated with EAH-kcal and EAH-% of savory foods, and BIS was positively associated with EAH-kcal and EAH-% overall, and with EAH-% of sweet foods (p < 0.05). There was little evidence of an interaction of BIS with PFS or m-YFAS.Conclusions: Findings demonstrate that EAH in pregnant women correlates with self-reported food reward sensitivity and occurs for both highly processed and low-processed foods. Self-control did not modify the positive association of food reward sensitivity with eating beyond satiation in this sample.

Power Of Food Scale

Background Greater sensitivity to food rewards and higher levels of impulsivity (and an interaction between these variables, termed “reinforcement pathology”) have been associated with obesity in cross-sectional studies. Less is known regarding how these constructs may impact attempts at weight loss or longer-term weight loss maintenance. Methods We provided 75 adults (69%Female, 84%White, age = 50.8y, BMI = 31.2kg/m2) with a 3-month Internet-based weight loss program and assessed weight, food reward sensitivity (via the Power of Food Scale [PFS]), and impulsivity (via Go No-Go [GNG] and Delay Discounting [DD] computer tasks) at baseline and at Months 3, 6, 9, and 12. No additional intervention was provided Months 3–12. Multi-level mixed-effect models were used to examine changes in PFS, GNG, and DD over time and associations between these measures and weight loss/regain. Results Participants lost 6.0±1.1kg Months 0–3 and regained 2.4±1.1kg Months 3–12. Across time points, higher PFS scores were associated with higher weight, p = .007; however, there were no significant associations between GNG or DD and weight nor between the interactions of PFS and GNG or DD and weight, ps>.05. There were significant decreases from Months 0–3 in PFS, GNG, and DD, ps < .05; however, neither baseline values nor changes were significantly associated with weight change and there were no significant associations between the interactions of PFS and GNG or DD and weight change, ps>.05. Conclusion Results demonstrated an association between food reward sensitivity and weight. Further, decreases in both food reward sensitivity and impulsivity were observed during an initial weight loss program, but neither baseline levels nor improvements were associated with weight change. Taken together, results suggest that the constructs of food reward sensitivity, impulsivity, and reinforcement pathology may have limited clinical utility within behavioral weight management interventions. Future intervention studies should examine whether food-related impulsivity tasks lead to a similar pattern of results.

AbstractGenetic variants associated with dietary intake may be important as factors underlying the development of obesity. We investigated the associations between the obesity candidate genes (fat mass and obesity-associated (FTO), melanocortin-4 receptor (MC4R), leptin (LEP) and leptin receptor) and total energy intake and percentage of energy from macronutrients and ultra-processed foods before and during pregnancy. A sample of 149 pregnant women was followed up in a prospective cohort in Rio de Janeiro, Brazil. A FFQ was administered at 5–13 and 30–36 weeks of gestation. Genotyping was performed using real-time PCR. Associations between polymorphisms and the outcomes were investigated through multiple linear regression and ANCOVA having pre-pregnancy dietary intake as a covariate. The A-allele of FTO-rs9939609 was associated with a −6·5 % (95 % CI −12·3, −0·4) decrease in the percentage of energy from protein and positively associated with the percentage of energy from carbohydrates before pregnancy (β=2·6; 95 % CI 0·5, 4·8) and with a 13·3 % (95 % CI 0·7, 27·5) increase in the total energy intake during pregnancy. The C-allele of MC4R-rs17782313 was associated with a −7·6 % (95 % CI −13·8, −1·0) decrease in the percentage of energy from protein, and positively associated with the percentage of energy from ultra-processed foods (β=5·4; 95 % CI 1·1, 9·8) during pregnancy. ANCOVA results revealed changes in dietary intake from pre-pregnancy to pregnancy for FTO-rs9939609 (percentage of energy from ultra-processed foods, P=0·03), MC4R-rs17782313 (total energy intake, P=0·02) and LEP-rs7799039 (total energy intake, P=0·04; percentage of energy from protein, P=0·04). These findings suggest significant associations between FTO-rs9939609, MC4R-rs17782313 and LEP-rs7799039 genes and the components of dietary intake in pregnant women.

The Impact

Abstract The present study evaluated the association of food addiction (FA), the change of the BMI/AgeZ-score, and the consumption of ultra-processed foods in overweight students undergoing a 16-month, multicomponent intervention in the school environment. FA was investigated using the Yale Food Addiction Scale for Children and the dietary assessment was estimated using the Semi-quantitative Food Frequency Questionnaire in overweight 9- to 11-year-old students (BMI/ageZscore≥1) of both sexes at their baseline and after the intervention (n=120). Among the schoolchildren, 33.4% had FA in at least one of the two assessments. The analysis of mixed-effects models to assess the effect of the intervention and the change of the BMI/AgeZ-score between evaluations showed that the occurrence of FA influenced the maintenance of weight (time#FA, β=0.30, 95%CI=0.05 to 0.54), p=0.016. Weight loss was observed only in individuals who did not present FA (BMI/Age Z-score= −0.3). When evaluating the effect of the intervention and the dietary variables, we verified a reduction in the consumption of sugary milk-based drinks (−17 kcal, p=0.04) only in non-FA students at the end of the study. FA has been identified as an underlying factor with therapeutic relevance, and an enhanced understanding of FA can open new paths for the prevention and management of obesity.

Uncontrolled Eating

Many eating-related psychological constructs have been proposed to explain obesity and over-eating. However, these constructs, including food addiction, disinhibition, hedonic hunger, emotional eating, binge eating, and the like all have similar definitions, emphasising loss of control over intake. As questionnaires measuring the constructs correlate strongly (r&gt;0.5) with each other, we propose that these constructs should be reconsidered to be part of a single broad phenotype: uncontrolled eating. Such an approach enables reviewing and meta-analysing evidence obtained with each individual questionnaire. Here, we describe robust associations between uncontrolled eating, body mass index (BMI), food intake, personality traits, and brain systems. Reviewing cross-sectional and longitudinal data, we show that uncontrolled eating is phenotypically and genetically intertwined with BMI and food intake. We also review evidence on how three psychological constructs are linked with uncontrolled eating: lower cognitive control, higher negative affect and a curvilinear association with reward sensitivity. Uncontrolled eating mediates all three constructs’ associations with BMI and food intake. Finally, we review and meta-analyse brain systems possibly subserving uncontrolled eating: namely, (i) the dopamine mesolimbic circuit associated with reward sensitivity, (ii) frontal cognitive networks sustaining dietary self-control, and (iii) the hypothalamus-pituitary-adrenal axis, amygdala and hippocampus supporting stress reactivity. While there are limits to the explanatory and predictive power of the uncontrolled eating phenotype, we conclude that treating different eating-related constructs as a single concept, uncontrolled eating, enables drawing robust conclusions on the relationship between food intake and BMI, psychological variables, and brain structure and function.

Experiencing a traumatic event is generally posited to increase vulnerability. Informed by a stress process framework, this study investigated the relation of posttraumatic stress to depressive symptoms, risky drinking, and school burnout in emerging adulthood, a developmental period during which common behavioral and psychological disorders reach their peak. Whether self-control acts as a mechanism linking posttraumatic stress to these outcomes was also examined. Using a short-term longitudinal design ( N = 373 undergraduate students), we found a direct, positive association between heightened levels of posttraumatic stress and heightened depressive symptoms, risky drinking, and school burnout. Posttraumatic stress was also indirectly linked to depressive symptoms, risky drinking, and school burnout via self-control. Experiences of posttraumatic stress are thought to erode self-control capacity, and depleted self-control is thought to be adversely associated with mental health, decision-making, and school success. Implications for intervention across multiple lines of defense are discussed.
