“…Specifically, self-efficacy had a positive effect on higher fruit and vegetable intake, whereas—contrary to hypotheses— perceived helplessness was not directly related to self-reported consumption of either food type. Conflicting results have emerged from prior research, with some studies finding stress associated with lower fruit/vegetable intake (Michels et al, 2012) and others finding no association with healthy food intake (Austin et al, 2009; Markus et al, 2012; Michels et al, 2012). Previous studies have used a variety of stress measures, from salivary cortisol to stressful life events.…”

“…Thus, the type of stress may impact how diet is affected. Yet study findings are inconclusive, with some studies finding no relationships between stress, emotional eating, and healthy eating habits (Austin, Smith, & Patterson, 2009; Markus, Verschoor, & Smeets, 2012). While previous research has shown a correlation between stress and unhealthy food intake, effects of stress on emotion-driven eating and healthy food intake remain unclear.…”

Objective Stress has been associated with high-calorie, low-nutrient food intake (HCLN) and emotion-driven eating (EDE). However, effects on healthy food intake remain unknown. This study examined two facets of stress (self-efficacy, perceived helplessness) and food consumption, mediated by EDE. Methods Cross-sectional data from fourth-graders (n = 978; 52% female, 28% Hispanic) in an obesity intervention used self-report to assess self-efficacy, helplessness, EDE, fruit/vegetable (FV) intake, and high-calorie/low-nutrient (HCLN) food. Results Higher stress self-efficacy was associated with higher FV intake, β = .354, p < 0.001, and stress perceived helplessness had an indirect effect on HCLN intake through emotion-driven eating, indirect effect = .094, p < 0.001; χ2(347) = 659.930, p < 0.001, CFI = 0.940, TLI = 0.930, RMSEA = 0.030, p = 1.00, adjusting for gender, ethnicity, BMI z-score, and program group. Conclusions and Implications Stress self-efficacy may be more important for healthy food intake and perceived helplessness may indicate emotion-driven eating and unhealthy snack food intake. Obesity prevention programs may consider teaching stress management techniques to avoid emotion-driven eating.

“…A broad range of well‐controlled experimental studies also reveal possible beneficial effects of dietary amino acids and carbohydrates (including sugar) on stress resilience, particularly in stress‐vulnerable subjects . For instance, in a human laboratory stress‐exposure study, only healthy subjects with a trait to vulnerability to frequently experiencing stress (neuroticism) exhibited significant reductions in negative mood and cortisol responsiveness under acute stress by exposures to specific nutrients .…”

SummaryDecades of research have reported only weak associations between the intakes of specific foods or drinks and weight gain and obesity. Randomized controlled dietary intervention trials have only shown very modest effects of changes in nutrient intake and diet composition on body weight in obese subjects. This review summarizes the scientific evidence on the role mental stress (either in or not in association with impaired sleep) may play in poor sleep, enhanced appetite, cravings and decreased motivation for physical activity. All these factors contribute to weight gain and obesity, possibly via decreasing the efficacy of weight loss interventions. We also review evidence for the role that lifestyle and stress management may play in achieving weight loss in stress-vulnerable individuals with overweight.

“…They showed that tryptophan intake significantly increased the plasma tryptophan in the L′/L′ group (70%) compared to the S′/S′ group (30%), but in both groups tryptophan intake reduced food consumption. However, tryptophan was able to reduce stress-induced negative mood and desire for sweet, high-fat foods only in the L′/L′ group (Markus et al, 2012). Results from a subsequent study suggested that 5-HTTLPR and neuroticism may influence stress-induced overeating depending on the type of food available (Capello and Markus, 2014a).…”

The differential susceptibility model states that a given genetic variant is associated with an increased risk of pathology in negative environments but greater than average resilience in enriched ones. While this theory was first implemented in psychiatric-genetic research, it may also help us to unravel the complex ways that genes and environments interact to influence feeding behavior and obesity. We reviewed evidence on gene vs. environment interactions that influence obesity development, aiming to support the applicability of the differential susceptibility model for this condition, and propose that various environmental “layers” relevant for human development should be considered when bearing the differential susceptibility model in mind. Mother-child relationship, socioeconomic status and individual's response are important modifiers of BMI and food intake when interacting with gene variants, “for better and for worse”. While only a few studies to date have investigated obesity outcomes using this approach, we propose that the differential susceptibility hypothesis is in fact highly applicable to the study of genetic and environmental influences on feeding behavior and obesity risk.
