Abstract
Disrupted hormonal appetite signaling plays a crucial role in obesity as it may lead to uncontrolled reward-related eating. Such disturbances can be induced not only by weight gain itself but also by glucocorticoid overexposure, for example, due to chronic stress, disease, or medication use. However, the exact pathways are just starting to be understood. Here, we present a conceptual framework of how glucocorticoid excess may impair hormonal appetite signaling and, consequently, eating control in the context of obesity. The evidence we present suggests that counteracting glucocorticoid excess can lead to improvements in appetite signaling and may therefore pose a crucial target for obesity prevention and treatment. In turn, targeting hormonal appetite signals may not only improve weight management and eating behavior but may also decrease detrimental effects of glucocorticoid excess on cardio-metabolic outcomes and mood. We conclude that gaining a better understanding of the relationship between glucocorticoid excess and circulating appetite signals will contribute greatly to improvements in personalized obesity prevention and treatment.

Leptin receptor co-expression gene network moderates the effect of early life adversity on eating behavior in children. Commun Biol 2022; 5:1092.

Abstract
Leptin influences eating behavior. Exposure to early adversity is associated with eating behaviour disorders and metabolic syndrome, but the role of the leptin receptor on this relationship is poorly explored. We investigated whether individual differences in brain region specific leptin receptor (LepR) gene networks could moderate the effects of early adversity on eating behavior and metabolism. We created an expression-based polygenic risk score (ePRS) reflecting variations in the function of LepR gene network in prefrontal cortex and hypothalamus to investigate the interactions between a cumulative index of postnatal adversity on eating behavior in two independent birth cohorts (MAVAN and GUSTO). To explore whether variations in the prefrontal cortex or hypothalamic genetic scores could be associated with metabolic measurements, we also assessed the relationship between LepR-ePRS and fasting blood glucose and leptin levels in a third independent cohort (ALSPAC). We identified significant interaction effects between postnatal adversity and prefrontal-based LepR-ePRS on the Child Eating Behavior Questionnaire scores. In MAVAN, we observed a significant interaction effect on food enjoyment at 48 months (β = 61.58, p = 0.015) and 72 months (β = 97.78, p = 0.001); food responsiveness at 48 months (β = 83.79, p = 0.009) satiety at 48 months (β = −43.63, p = 0.047). Similar results were observed in the GUSTO cohort, with a significant interaction effect on food enjoyment (β = 30.48, p = 0.006) food fussiness score (β = −24.07, p = 0.02) and satiety score at 60 months (β = −17.00, p = 0.037). No effects were found when focusing on the hypothalamus-based LepR-ePRS on eating behavior in MAVAN and GUSTO cohorts, and there was no effect of hypothalamus and prefrontal cortex based ePRSs on metabolic measures in ALSPAC. Our study indicated that exposure to postnatal adversity interacts with prefrontal cortex LepR-ePRS to moderate eating behavior, suggesting a neurobiological mechanism associated with the development of eating behavior problems in response to early adversity. The knowledge of these mechanisms may guide the understanding of eating patterns associated with risk for obesity in response to fluctuations in stress exposure early in life. An expression-based polygenic risk score analysis of leptin receptor (LepR) genes suggests that LepR-specific genes co-expressed in the prefrontal cortex interact with exposure to postnatal adversity, potentially modulating eating behavior in children.

Time of day differences in appetite and gut hormone responses to meal and stress challenges in adults with normal-weight and obesity. Physiol Behav 2022; 254:113890. [PMID: 35750246 DOI: 10.1016/j.physbeh.2022.113890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2021] [Revised: 06/03/2022] [Accepted: 06/19/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND . Lifestyle factors like time of eating and stress exposure may impact physiology to promote excess weight gain. To understand behavioral and physiological mechanisms underlying these potential effects, we compared appetite and gut hormone responses to a series of meal and stress challenges beginning in the morning and the afternoon, in adults with normal-weight and obesity. METHOD . Thirty-two adults (16 with normal-weight, 16 with obesity) underwent the same test protocol on different days, each following an 8 h fast. On one day the protocol began in the morning (AM condition); on the other day it began in the late afternoon (PM condition). On each day they first received a standardized liquid meal (9:00am/4:00pm), then a stress test (Socially-Evaluated Cold Pressor Test, 11:10am/6:10pm), then an ad libitum buffet meal (11:40am/6:40pm). Appetite and stress ratings were obtained, and blood was drawn for measures of ghrelin, PYY, GLP-1, insulin, glucose, cortisol and leptin. Acetaminophen was administered as a tracer to assess gastric emptying of the liquid meal. RESULTS . Across all three challenges, AUC cortisol was lower in the PM vs. AM condition (all p<.001), and AUC insulin and leptin were higher in the obesity vs. normal-weight group (all p<.001). For the standardized liquid meal only, AUC hunger, desire to eat and ghrelin were greater in the PM vs. AM condition (all p<0.05), and AUC ghrelin was lower in the obesity vs. normal-weight group, even when controlling for baseline values (p<0.05). AUC glucose was higher in the evening for the normal-weight group only (condition x group interaction p<0.05). Post-liquid meal gastric emptying as indexed by AUC acetaminophen was slower in the PM vs. AM (p<.01). For the stress test, AUC cortisol was lower in the PM than the AM condition even when controlling for baseline values (p<.05). AUC leptin was lower in the evening in the obesity group only (condition x group interaction p<0.01). PYY showed an acute decrease post-stressor in the normal-weight but not the obesity group (p<.05). Post-stress ad libitum buffet meal intake was similar in the evening and morning conditions, and higher in the obesity group (p<0.05). Only among the obesity group in the evening condition, higher stressor-associated stress ratings were associated with lesser fullness in relation to the buffet meal (p<0.05). CONCLUSIONS . Normal-weight individuals and those with obesity may be at risk of evening overeating as a result of differential appetite and gut hormone responses following meal intake and stress exposure.

Abstract
INTRODUCTION binge eating disorder (BED) is characterized by eating much more than what most people would eat under similar circumstances. Inability to cope with stress and emotions may be the reason for BED episodes. OBJECTIVE to assess the level of stress and BED severity based on the number of episodes of compulsive overeating among patients attending nutrition counseling. METHODS a total of 100 people (60 women and 40 men) were taking part in the study. A questionnaire in which subjects answered questions concerning diet, number of meals, and coping with stressful situations was used. A nutritional diary was used to assess the amount of BED episodes and consumed products, and the emotions felt during consumption. PSS-10 was used to measure the response to stressful situations. RESULTS all subjects had episodes of compulsive overeating but the majority of respondents (52 %) had no more than 3 episodes of binge eating per week. During a BED episode patients most often chose sweets (58.2 %). The main way of responding of people on stressful situations was snacking, especially sweets. CONCLUSIONS high levels of stress correlated positively with the number of BED episodes and excessive body weight. The PSS-10 questionnaire could be a useful tool in nutrition counseling.

Abstract
It is well known that stress elevates intake of total calories and shifts food preference toward unhealthy food choices. There is, however, little known on the physiological mechanisms that drive stress-induced hyperphagia. In order to better understand how to reduce stress eating, it is critical to identify mechanisms in humans that are points of convergence between stress and eating. The feeding-related hormones ghrelin, leptin, glucagon-like peptide-1 (GLP-1), and amylin are likely candidates. It was hypothesized that ghrelin, an orexigenic hormone, would increase in response to an acute laboratory stressor, but that leptin, GLP-1, and amylin (anorexigenic hormones) would decrease after stress. To this aim, participants (n = 47) came into the laboratory and had feeding-related hormones, salivary cortisol and α-amylase, and self-rated anxiety measured. Then they underwent either exposure to a stressor (n = 24), which reliably elevates measures of stress and energy intake, or a no-stress condition (n = 23). Feeding hormones, stress hormones, and self-rated anxiety were measured twice more after the stressor. Elevated self-rated anxiety and α-amylase confirmed the validity of the stressor. Furthermore, there was a time X condition interaction for both ghrelin and GLP-1. Ghrelin was significantly elevated after stress compared to baseline (p = .02) and there was a trend for GLP-1 to be higher in the stress condition over the no-stress condition immediately after the stressor (p = .07). Overall, ghrelin is the most likely candidate driving energy intake after stress in humans.

Abstract
Stress leads to detrimental health outcomes through direct biological and indirect behavioural changes. Stress can lead to disruption to normal eating behaviours, although the strength of these associations is unknown. This is the first meta-analysis to determine the strength of the stress-eating relationship in healthy adults and to explore the impact of potential moderators. Studies included had a clearly defined measure of stress (i.e., any noxious event or episode in one's environment with the exclusion of emotional distress) that was linked to non-disordered eating. Key terms were searched in Medline, PsycInfo and Ovid databases (23,104 studies identified). 54 studies (combined N = 119,820) were retained in the meta-analysis. A small, positive effect size was found for the stress-overall food intake relationship (Hedges' g = 0.114). Stress was associated with increased consumption of unhealthy foods (Hedges' g = 0.116) but decreased consumption of healthy foods (Hedges' g = -0.111). Only one significant moderator (restraint on stress-unhealthy eating) was identified. This meta-analysis identified the magnitude of the effect of stress on eating behaviour outcomes. Significant heterogeneity was observed that was not explained by the moderators examined. Further research on moderators of the stress-eating relationship is required and should distinguish effects for healthy versus unhealthy eating.

Abstract
BACKGROUND Given previous research suggests an association between stress and the intake of energy-dense foods, this study investigated whether poststressor relaxation practice can attenuate stress-induced eating. METHODS Twenty-five men and women were exposed to four conditions on separate days: an acute laboratory stressor (S), acute stressor followed by 20 min of relaxation (SR) in the form of Abbreviated Progressive Muscle Relaxation (APMR), relaxation alone (R), and a control condition (C). Physiological and psychological responses to stress and relaxation were assessed, in addition to the subsequent energy intake of high-energy snacks. RESULTS Salivary cortisol, blood pressure, heart rate, and perceived stress were transiently elevated postlaboratory stressor (S and SR compared with R and C; p < .05). Meanwhile, perceived relaxation was acutely enhanced after APMR alone (R) compared with S, SR, and C (p < .05) and in SR (immediately after the APMR) compared with S (p < .05). No difference in mean energy intake was observed between conditions (p > .05). Likewise, no differences in perceived appetite or the levels of ghrelin, leptin, and insulin were found between conditions (p > .05). CONCLUSIONS Much variation exists in stress-induced dietary responses, and APMR either postacute stressor or in isolation does not appear to consistently alter the intake of commonly eaten snacks.

Abstract
Many pathways connect stress and obesity, two highly prevalent problems facing society today. First, stress interferes with cognitive processes such as executive function and self-regulation. Second, stress can affect behavior by inducing overeating and consumption of foods that are high in calories, fat, or sugar; by decreasing physical activity; and by shortening sleep. Third, stress triggers physiological changes in the hypothalamic-pituitary-adrenal axis, reward processing in the brain, and possibly the gut microbiome. Finally, stress can stimulate production of biochemical hormones and peptides such as leptin, ghrelin, and neuropeptide Y. Obesity itself can be a stressful state due to the high prevalence of weight stigma. This article therefore traces the contribution of weight stigma to stress and obesogenic processes, ultimately describing a vicious cycle of stress to obesity to stigma to stress. Current obesity prevention efforts focus solely on eating and exercise; the evidence reviewed in this article points to stress as an important but currently overlooked public policy target.

Abstract
OBJECTIVE Psychosocial stress can be a health threat by stimulating unhealthier eating behaviors. We aim to test the role of the hormone leptin in the association between stress and diet/emotional eating as detected in primary school children. METHOD In a two-wave longitudinal study with 308 Belgian children (5-12y) in 2010-2012, the association of fasting serum leptin with reported stress (negative events and emotional problems), measured stress by salivary cortisol (overall cortisol output and awakening response), emotional eating and food consumption frequency was examined. Analyses were split by sex. Mediation and moderation by leptin change were tested. RESULTS One stress marker (overall cortisol output) was significantly correlated with high leptin levels, but only in girls and cross-sectionally. Only in boys, leptin was associated with low emotional eating. Leptin was not a significant predictor of unhealthy food consumption. Leptin change was not a mediator but an enhancing moderator in the link between stress (high cortisol output and emotional problems) and emotional eating in girls: high reports of emotional eating in 2012 were present in the case of combined high 2-year leptin increase and high stress at baseline. DISCUSSION Stress (represented by emotional problems and high daily cortisol) seems to lead to hyperleptinemia in girls; and the combination of high stress and hyperleptinemia might make girls more vulnerable to stress-induced eating. No functional data on leptin sensitivity were present, but results might suggest that stress induces lower sensitivity to the anorexigenic leptin activity. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2017; 50:471-480).

Abstract
BACKGROUND The human Aldoketoreductase 1B10 gene (AKR1B10) encodes one of the enzymes belonging to the family of aldoketoreductases and may be involved in detoxification of nutrients during digestion. Further, AKR1B10 mRNA (messenger ribonucleic acid) expression was diminished in brain regions potentially involved in the regulation of eating behavior in rats which are more sensitive to cocaine and alcohol. We hypothesized that the human AKR1B10 gene may also play a role in the regulation of human eating behavior. RESULTS We investigated the effects of 5 genetic variants of AKR1B10 on human eating behavior among 548 subjects from a German self-contained population, the Sorbs, and in 350 subjects from another independent German cohort. Among the Sorbs, we observed nominal associations with disinhibition at the 5' untranslated region (5' UTR) variant rs10232478 and the intragenic variants rs1834150 and rs782881 (all P ≤ 0.05). Further, we detected a relationship of rs1834150 and rs782881 with waist, smoking consumption (rs782881) and coffee consumption (rs1834150) (all P ≤ 0.05). Albeit non-significant, replication analyses revealed similar effect directions for disinhibition at rs1834150 (combined P = 0.0096). Moreover, in the replication cohort we found rs1834150 related to increased restraint scores with a similar direction as in the Sorbs (combined P = 0.0072). CONCLUSION Our data suggest that genetic variants in the AKR1B10 locus may influence human eating behavior.

Abstract
Impulsivity towards food has been recognized as a potential factor leading to increased food intake in obesity. Patients suffering from binge eating disorder (BED) form a specific subgroup of obese people that might be characterized by increased impulsivity. These assumptions, although, have yet to be verified. Therefore, this review evaluates evidence for food-related impulsivity in obese people with and without BED and examines possible differences between both populations. More precisely, evidence for the two components of impulsivity is analyzed separately: evidence for reward sensitivity, specifically, the urge for appetitive stimuli and evidence for rash-spontaneous behaviour such as acting disinhibited with no regard for the consequences. Our search resulted in 51 articles demonstrating generally increased food-related impulsivity. We found particular emphasis on increased reward sensitivity in obese people, which appeared to be more pronounced in people with BED. There was little and conflicting evidence, however, concerning increased rash-spontaneous behaviour in obese people without BED, but consistent evidence of an increase in obese people with BED. All in all, the evidence supports the view that BED represents a specific phenotype of obesity with increased food-related impulsivity. Taking these specific deficits into account can enhance the effectiveness of weight reduction programmes and psychotherapy.

Abstract
Neural systems that identify and respond to salient stimuli are critical for survival in a complex and changing environment. In addition, interindividual differences, including genetic variation and hormonal and metabolic status likely influence the behavioral strategies and neuronal responses to environmental challenges. Here, we examined the relationship between leptin allelic variation and plasma leptin levels with DAD2/3R availability in vivo as measured with [(11)C]raclopride PET at baseline and during a standardized pain stress challenge. Allelic variation in the leptin gene was associated with varying levels of dopamine release in response to the pain stressor, but not with baseline D2/3 receptor availability. Circulating leptin was also positively associated with stress-induced dopamine release. These results show that leptin serves as a regulator of neuronal function in humans and provides an etiological mechanism for differences in dopamine neurotransmission in response to salient stimuli as related to metabolic function. The capacity for leptin to influence stress-induced dopaminergic function is of importance for pathological states where dopamine is thought to play an integral role, such as mood, substance-use disorders, eating disorders, and obesity.

Physiol Behav 2012; 107:34-9. [PMID: 22579988 DOI: 10.1016/j.physbeh.2012.04.021] [Citation(s) in RCA: 55] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2011] [Revised: 04/03/2012] [Accepted: 04/24/2012] [Indexed: 01/07/2023]
Abstract
Both animals and humans show a tendency toward eating more "comfort food" (high fat, sweet food) after acute stress. Such stress eating may be contributing to the obesity epidemic, and it is important to understand the underlying psychobiological mechanisms. Prior investigations have studied what makes individuals eat more after stress; this study investigates what might make individuals eat less. Leptin has been shown to increase following a laboratory stressor, and is known to regulate satiety. This study examined whether leptin reactivity accounts for individual differences in stress eating. To test this, we exposed forty women to standardized acute psychological laboratory stress (Trier Social Stress Test) while blood was sampled repeatedly for measurements of plasma leptin. We then measured food intake after the stressor. Increasing leptin during the stressor predicted lower intake of comfort food. These initial findings suggest that acute changes in leptin may be one of the factors modulating down the consumption of comfort food following stress.
