Abstract
Adolescents are increasingly interested in weight control; hence, proper health education is important for helping them control their weight properly. This study was designed to pick out social media words that express adolescents’ diet behaviors, and identify the associations and types between such words and the behaviors. It used text-mining techniques and semantic network analysis for related big data collected from the Internet on adolescents’ diet behaviors. Text mining was used to extract meaningful information from unstructured text data, whereas semantic network analysis was used to understand the relationships between keywords. The top five keywords were “obesity,” “health,” “exercise,” “eat,” and “increase” in online news, and “exercise,” “eat,” “weight loss,” “obesity,” and “health” in blogs. The betweenness centrality of “appearance” was particularly higher than that of other centralities in online news. As a result of the CONCOR analysis, eight clusters each were identified in online news and blogs. This study’s results will serve as a basis for weight management-related intervention strategies, reflecting the perspectives of adolescents. It also has significance as basic data to provide correct information, and establish desirable weight control in the future.

Oliveira JD. The body asks and the mind judges: the episode of food craving, its triggers and nutritional treatment. EINSTEIN-SAO PAULO 2022; 20:eMD6705.

Abstract
Food desires are defined as motivations that drive the search for and consumption of food. However, when domains of intensity and urgency are activated, these desires can become intense (i.e. food craving), being then characterized by episodes or cognitive events loaded with affectivity, in which food is associated with obtaining pleasure or relief, which is the only attentional focus. Specificity and urgency mark the differentiation between food desires and cravings. The process of elaboration with vivid images, the retention in working memory, the emergence of a negative affect state (awareness of the lack), and a committed attentional focus to seek food are characterized as stages of an episode of food craving. Individuals with eating disorders have the lowest levels of food craving when it comes to anorexia nervosa and the subsequent increase to bulimia nervosa and binge eating disorder. Some environmental and cultural triggers and internal factors of cognition and emotions play a crucial role in the emergence of food craving episodes. The external factors include positive/negative events, food environment, advertisements, cultural beliefs about food, specific locations, and food itself. The internal factors comprise dietary restriction, food reward, impulsivity/inflexibility, emotions, thoughts and feelings about food, hunger/satiety/appetite, and anxious/depressive symptoms. Treatment involves the association of flexibility, awareness, and questioning strategies about dietary practices based on three principles: unconditional permission to eat, eating more for physical than emotional reasons, and tuning in with the body’s signs of hunger and satiety (intuitive eating).

Abstract
This systematic review examined the effectiveness of policies restricting the marketing of foods and/or non-alcoholic beverages to children to inform updated World Health Organization (WHO) guidelines. Databases were searched to March 2020. Inclusion criteria were primary studies of any design assessing implemented policies to restrict food marketing to children (0-19 years). Critical outcomes were exposure to and power of marketing, dietary intake, choice, preference, and purchasing. Important outcomes were purchase requests, dental caries, body weight, diet-related noncommunicable diseases, product change, and unintended consequences. Forty-four observational studies met inclusion criteria; most were moderate quality. Pooling was conducted using vote counting by direction of effect, and GRADE was used to judge evidence certainty. Evidence suggests food marketing policies may result in reduced purchases of unhealthy foods and in unintended consequences favorable for public health. Desirable or potentially desirable (for public health) effects of policies on food marketing exposure and power were also found. Evidence on diet and product change was very limited. The certainty of evidence was very low for four outcomes (exposure, power, dietary intake, and product change) and low for two (purchasing and unintended consequences). Policies can effectively limit food marketing to children; policymakers should prioritize mandatory approaches aligned with WHO recommendations.

Abstract
The prefrontal cortex is appreciated as a key neurobiological player in human eating behavior. A special focus is herein dedicated to the dorsolateral prefrontal cortex (DLPFC), which is critically involved in executive function such as cognitive control over eating. Persons with obesity display hypoactivity in this brain area, which is linked to overconsumption and food craving. Contrary to that, higher activity in the DLPFC is associated with successful weight-loss and weight-maintenance. Transcranial direct current stimulation (tDCS) is a non-invasive neurostimulation tool used to enhance self-control and inhibitory control. The number of studies using tDCS to influence eating behavior rapidly increased in the last years. However, the effectiveness of tDCS is still unclear, as studies show mixed results and individual differences were shown to be an important factor in the effectiveness of non-invasive brain stimulation. Here, we describe the current state of research of human studies using tDCS to influence food intake, food craving, subjective feeling of hunger and body weight. Excitatory stimulation of the right DLPFC seems most promising to reduce food cravings to highly palatable food, while other studies provide evidence that stimulating the left DLPFC shows promising effects on weight loss and weight maintenance, especially in multisession approaches. Overall, the reported findings are heterogeneous pointing to large interindividual differences in tDCS responsiveness.

Abstract
Cravings for a range of substances including drugs, alcohol, and food have been shown to predict subsequent consumption or use. However, this link has not yet been systematically examined for beverages other than alcohol. The present study aimed to provide a comprehensive investigation of cravings for non-alcoholic beverages and their link to consumption. Participants were 128 undergraduate students (17-25 years) who completed a craving diary and daily consumption measure over a period of a week. Cravings were reported for a range of beverages, including tea, juice, and flavoured milk, but by far the most craved beverages were water, coffee, and soft drink. Stronger cravings were associated with a greater likelihood of drinking and drinking more of the craved beverage. This was particularly the case for soft drink. Unlike water, cravings for coffee and soft drink were triggered by factors other than thirst, and the number of cravings predicted the total amount drunk over the week. The findings demonstrate the existence of cravings for non-alcoholic beverages such as soft drink, and point to these cravings as a potential target for reducing consumption.

Abstract
Elevated brain reward and attention region response, and weaker inhibitory region response to high-calorie foods has predicted future weight gain, suggesting that an intervention that reduces reward and attention region response and increases inhibitory region response to such foods might reduce overeating. We conducted a randomized controlled trial to test whether a multi-faceted food response and attention training protocol with personalized high- and low-calorie food images would reduce body fat and valuation and reward region response to high-calorie foods compared to a placebo control training protocol with non-food images in an effort to replicate findings from two past trials. Participants were community-recruited adults with overweight/obesity (N = 179; M age = 27.7 ± 7.0) who completed assessments at pretest, posttest, 3-month, 6-month, and 12-month follow-ups. Participants randomized to the food response inhibition and attention training showed significantly greater increases in palatability ratings of low-calorie foods than controls (d = 0.27) at posttest, but did not show body fat loss, reductions in palatability ratings and monetary valuation, or reward region response, to high-calorie foods. The lack of expected effects appears to be related to weaker learning compared to the learning in past trials, potentially because we used more heterogenous high-calorie and low-calorie food images in the present training.

Associations between average step counts, variability in step counts and nonhomeostatic eating. Eat Weight Disord 2022; 27:2165-2171.

Abstract
PURPOSE Nonhomeostatic drives (e.g., reward and negative emotion) for eating are associated with weight gain over time. Higher average and lower intraindividual variability in physical activity (PA) levels are positively associated with health and weight outcomes, but have not been evaluated in relation to nonhomeostatic eating. The aim of this paper is to examine the associations between PA and nonhomeostatic drives for eating. The hypotheses were that average levels of and consistency in PA would be negatively correlated with nonhomeostatic eating. METHODS Adult participants (N = 432) were recruited online and asked to report objectively measured PA using commercially available PA monitors for the previous 7 days and to complete self-report measures of reward-driven and emotional eating. RESULTS Average daily steps (M = 6519.36) were negatively associated with emotional eating, but were not significantly related to reward-driven eating. Intraindividual variability in steps (M = 2209.85) was not associated with either type of nonhomeostatic eating. Adjusting for relevant covariates (e.g., age, BMI, gender), average daily step count was negatively associated with emotional eating (p = 0.01) but not reward-driven eating (p = 0.31) and variability in step counts was positively associated with reward-driven eating (p = 0.04) but not emotional eating (p = 0.52). CONCLUSION The results suggest that greater average levels and lower variability in PA are related to lower nonhomeostatic eating; thus, complex associations between PA and eating exist, and may impact weight and outcomes of treatment related to eating and weight.

Abstract
The modern obesogenic environment contains an abundance of food cues (e.g., sight, smell of food) as well cues that are associated with food through learning and memory processes. Food cue exposure can lead to food seeking and excessive consumption in otherwise food-sated individuals, and a high level of food cue responsivity is a risk factor for overweight and obesity. Similar food cue responses are observed in experimental rodent models, and these models are therefore useful for mechanistically identifying the neural circuits mediating food cue responsivity. This review draws from both experimental rodent models and human data to characterize the behavioral and biological processes through which food-associated stimuli contribute to overeating and weight gain. Two rodent models are emphasized - cue-potentiated feeding and Pavlovian-instrumental transfer - that provide insight in the neural circuits and peptide systems underlying food cue responsivity. Data from humans are highlighted that reveal physiological, psychological, and neural mechanisms that connect food cue responsivity with overeating and weight gain. The collective literature identifies connections between heightened food cue responsivity and obesity in both rodents and humans, and identifies underlying brain regions (nucleus accumbens, amygdala, orbitofrontal cortex, hippocampus) and endocrine systems (ghrelin) that regulate food cue responsivity in both species. These species similarities are encouraging for the possibility of mechanistic rodent model research and further human research leading to novel treatments for excessive food cue responsivity in humans.

Change in craving and frequency of consuming palatable foods for non-homeostatic motives after a gut-cued eating intervention. Eat Behav 2022; 46:101656.

Abstract
INTRODUCTION Little is known regarding consumption of palatable foods (PFs) for non-homeostatic reasons after weight-loss interventions and if baseline or change in frequency of this kind of eating can predict weight-loss outcomes. Little is also known of the relationship between PF eating for non-homeostatic motives and PF craving. Addressing these gaps is important because cravings and habitual consumption of PFs in the absence of homeostatic need contribute to obesity. METHODS N = 30 adults with a mean 34.8 BMI completed a seven-response choice version of the PEMS (PEMS-7) before and after Gut-Cued Eating (GCE), an intervention that did not ban PFs but instructed them to eat only when stomach-hungry and stop eating before feeling too full. Photos of PFs were also rated pre- and post-GCE. RESULTS Frequency of eating PFs for social, reward enhancement, and coping, but not conformity motives, decreased after GCE. The decreases predicted amount of weight loss independent of initial weight and demographics. PF craving also decreased and, while correlated with decreasing PF intake, it did not predict weight loss. DISCUSSION The study is preliminary because GCE was uncontrolled. However, results warrant a controlled investigation. That craving and frequency of consuming PFs for non-homeostatic motives declined with an intervention that did not ban PFs suggests a method that may voluntarily decrease one's intake of PFs. This should facilitate weight-loss and healthy-weight maintenance. Finally, decreased eating for non-homeostatic motives suggests that individuals were no longer using PFs to cope, socialize, and enhance reward, a change with benefits beyond weight loss.

Abstract
This Current Opinion in Behavioral Sciences article reviews trials that evaluated an obesity treatment that combines response-inhibition training with high-calorie foods and training designed to reduce attention for high-calorie foods. Two randomized controlled trials suggest that food-response inhibition and attention training produced significant body-fat loss, along with a reduction in valuation of, and reward-region response to, high-calorie foods. However, these effects did not emerge in a third trial, potentially because this trial used more heterogeneous food images, which reduced inhibition learning and attentional learning. Collectively, results suggest that food-response inhibition and attention training can devalue high-calorie foods and result in weight loss, but only if a homogeneous set of high-calorie and low-calorie food images is used.

Abstract
This review aims to draw attention to current studies on syndromes related to food eating behavior, including food addiction, and to highlight the neurobiological and neuropharmacological aspects of food addiction toward the development of new therapies. Food addiction and eating disorders are influenced by several neurobiological factors. Changes in feeding behavior, food addiction, and its pharmacological therapy are related to complex neurobiological processes in the brain. Thus, it is not surprising that there is inconsistency among various individual studies. In this review, we assessed literature including both experimental and clinical studies regarding food addiction as a feeding disorder. We selected articles from animal studies, randomized clinical trials, meta-analyses, narrative, and systemic reviews given that, crucial quantitative data with a measure of neurobiological, neuropharmacological aspects and current therapies of food addiction as an outcome. Thus, the main goal to outline here is to investigate and discuss the association between the brain reward system and feeding behavior in the frame of food addiction in the light of current literature.

Abstract
INTRODUCTION Previous research has identified reward sensitivity as an important factor that may contribute to the engagement in eating behavior (e.g., binge eating, emotional eating, etc.) and increase obesity risk. In the current study, we conducted a systematic review of the literature to determine the relationships between reward sensitivity, eating behavior, and obesity-related outcomes. The study focused on two commonly used measures of reward sensitivity in the literature: the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ) and the Behavioral Inhibition Scale/Behavioral Activation Scale (BIS/BAS Scale). METHOD We conducted a systematic search to identify studies that analyzed reward sensitivity as a predictor of eating behavior or obesity-related outcomes, and measured reward sensitivity using the SPSRQ or BIS/BAS Scale. The search yielded N=19 total publications included in the review. RESULTS Findings indicated that reward sensitivity, primarily measured by summary scores on the SPSRQ or BIS/BAS Scale, were positively associated with a variety of eating behaviors and obesity-related outcomes with small to moderate effect sizes. Findings were most consistent across studies that examined the association between reward sensitivity and eating behavior outcomes (e.g., binge eating, emotional eating) (r values= .08 to .41; p values < .001 to p < .05) and food consumption outcomes (e.g., palatable food intake) (r values = .21 to .40; p < .001 to p values < .05). Findings were less consistent for food craving and BMI outcomes, and revealed these relationships may depend on individual-level factors and/or environment-related factors, (e.g., food cues). A quality evaluation using the Critical Appraisal Tool for Cross-Sectional Studies (AXIS tool) indicated that most studies were rated as moderate to strong quality (84%). CONCLUSION Findings indicate that elevated reward sensitivity may be a risk factor for engagement in eating behaviors that may increase obesity risk.

Abstract
Overweight and obesity rates have increased worldwide in the last decades. The marketing strategies of food considered to be unhealthy significantly exacerbate the childhood obesity dilemma. Studies typically analyze the content of advertisement in television, movies, or social media, but there is a gap in the assessment of the real-life promotion of food and beverages around the schools. The primary aim of the study was to assess the products advertised around public and concerted schools in three cities in the north of Spain, and to categorize them as healthy (core) or unhealthy (discretionary). The secondary aim was to describe the types of food and beverages in advertisements, as well as to determine the density of core and discretionary product advertisements. A cross-sectional descriptive study was carried out between September and December 2021. The units of analysis were outdoor food and beverage advertisements that were located around public and concerted schools of three cities in the north of Spain. We found 104 schools that met the criteria. We identified 6469 products advertised, 35.1% core and 61.2% discretionary, observing significant differences (p < 0.001) among the cities. Fruit (core) and alcohol (discretionary) were the most heavily advertised products. In conclusion, children attending schools located in the assessed cities are currently exposed to a significant amount of discretionary product advertisement, a situation that should be regulated.

Abstract
Abstract
Purpose of Review
The majority of existing research discusses food addiction (FA) classification, which provides information for different groups and which groups may or may not be affected to differing degrees. Fewer studies report FA symptom scores, and fewer still report on individual symptoms. This paper discusses the symptoms of craving and loss of control as they are common FA symptoms that demonstrate similarities with both substance use disorders and some eating disorder pathology.
Recent Findings
Loss of control presents parallels with disordered eating, particularly binge eating disorder. Craving refers to the powerful or strong desire for something and, in contrast to lack of control, presents most overlap with substance use disorders.
Summary
While not the most common symptoms reported in published research, loss of control and craving attract attention because of parallels with substance use and eating disorder pathology, and research has increasingly focused on these symptoms in recent years.

INTRODUCTION The COVID-19 pandemic with its protective measures (e. g. lockdown) had far-reaching effects on everyone's well-being. The aim of this study was to examine lifestyle variables during the first Austrian lockdown in patients with bipolar disorder in comparison to a healthy control group and to assess subjective changes caused by the pandemic. METHOD At the beginning of April 2020, an online survey of n=75 participants (35 people with bipolar disorder and 40 healthy controls) with standardized questionnaires (Beck Depression Inventory-2, Food Craving Inventory, Altman Self Rating Mania Scale) as well as non-standardized COVID-19-specific questions on the subject of "Psychological stress and effects of the COVID-19 pandemic in bipolar disorder" was created and distributed via LimeSurvey. RESULTS Both groups reported a negative impact on their mental health. The participants with bipolar disorder showed significantly higher values in the Beck Depression Inventory-2 score (p<0,001), in emotional distress due to social distancing (p=0,003) and significantly lower values in muscle-strengthening exercise (p=0,039) and in sport units (p=0,003) compared to the control group. In addition, patients with bipolar disorder smoked more often than individuals of the control group. People with bipolar disorder were 42,9% more likely to report they were less efficient during the pandemic, and 22,9% experienced weight gain compared to before the pandemic. The control group, on the other hand, was less efficient at 17,5% and 5,0% reported weight gain. However, a comparison with pre-pandemic data showed a decrease in food craving in both groups. CONCLUSION This study provided first evidence of self-reported adverse effects on mental stress and lifestyle in people with bipolar disorder at the beginning of the COVID-19 pandemic. Psychiatric care and early interventions for patients with bipolar disorder would be particularly important in times of crisis in order to help maintain a healthy lifestyle and thus counteract unfavourable developments.

Abstract
Previous studies have demonstrated that response inhibition training can modify the appeal of palatable and energy-dense foods, thus serving as a potential intervention for weight management, via changes in food selection and intake. However, empirical findings of efficacy have been inconsistent across studies due to heterogenous approaches to measuring salient appetitive outcomes, training implementation strategies, and sample recruitment. Systematic assessment of both affective and motivational components of food reward may help characterise to what extent devaluation can be generalised to nutritionally similar foods post-training. In this mixed factorial experiment, a non-clinical, adult sample completed time-matched single sessions with mobile app-based response inhibition training and control tasks of short (12 min; n = 27) or long (20 min; n = 25) duration. Participants were assessed on two discrete facets of food reward pre- and post-training: pleasure (i.e., explicit liking) and desire (i.e., implicit wanting) for non-specific (i.e., novel) food stimuli differing in energy-density. Consumption of snacks categorised by energy density was also assessed in a laboratory ad libitum taste test post-training. No significant differences were found between intervention and control sessions on explicit liking or implicit wanting for non-specific energy-dense foods. Moreover, participants ate a similar volume of snack foods during both sessions. Training duration did not significantly moderate differences between intervention and control sessions in primary outcomes. Variance between intervention and control sessions in chocolate intake and frequency of choice for energy-dense foods, but not explicit liking, was associated with a higher BMI. Methodological and theoretical implications for appropriate intervention implementation and underlying mechanisms, respectively, are discussed.

Abstract
The ASN Board of Directors appointed the Nutrition Research Task Force to develop a report on scientific methods used in nutrition science to advance discovery, interpretation, and application of knowledge in the field. The genesis of this report was growing concern about the tone of discourse among nutrition professionals and the implications of acrimony on the productive study and translation of nutrition science. Too often, honest differences of opinion are cast as conflicts instead of areas of needed collaboration. Recognition of the value (and limitations) of contributions from well-executed nutrition science derived from the various approaches used in the discipline, as well as appreciation of how their layering will yield the strongest evidence base, will provide a basis for greater productivity and impact. Greater collaborative efforts within the field of nutrition science will require an understanding that each method or approach has a place and function that should be valued and used together to create the nutrition evidence base. Precision nutrition was identified as an important emerging nutrition topic by the preponderance of task force members, and this theme was adopted for the report because it lent itself to integration of many approaches in nutrition science. Although the primary audience for this report is nutrition researchers and other nutrition professionals, a secondary aim is to develop a document useful for the various audiences that translate nutrition research, including journalists, clinicians, and policymakers. The intent is to promote accurate, transparent, verifiable evidence-based communication about nutrition science. This will facilitate reasoned interpretation and application of emerging findings and, thereby, improve understanding and trust in nutrition science and appropriate characterization, development, and adoption of recommendations.

Abstract
OBJECTIVE Among the major impediments to successful smoking cessation are strong cravings, especially during times of heightened stress. Affective responses to stress (e.g., acute anxious and depressed mood) may serve as important mediators of cigarette cravings that are amenable to intervention. Experimental models have been developed to reliably induce cravings during stress under laboratory conditions, permitting a closer examination of possible changes in affect that may be driving cigarette cravings. A key limitation of the extant research is its reliance on samples of predominantly White males who smoke. Although several recent studies suggest possible gender- and race/ethnicity-based differences in affective responses to acute stress, no studies have explored how such differences may contribute to cigarette cravings. METHOD To address this gap, we conducted an experimental study in which a diverse sample of healthy volunteer female (n = 163) and male (n = 139) nicotine-dependent individuals who smoked were exposed to a stressor (guided imagery of painful dental work). We assessed negative affect and cigarette craving immediately before and after the imaginal dental stressor. RESULTS Path analyses revealed that the acute stressor induced increases in negative affect, which, in turn, increased cigarette craving (significant direct and indirect effects, p's < 0.05; R2indirect = 0.5). Interestingly, effects were more pronounced in women and in non-White individuals who smoked. CONCLUSIONS Results highlight the important roles of stress and affect in craving, and the need to consider gender and race/ethnicity when developing interventions to manage stress-induced cigarette cravings among individuals attempting to quit.

Abstract
Importance Craving, which is a strong desire for drugs, is a new DSM-5 diagnostic criterion for substance use disorders (SUDs), which are the most prevalent, costly, and deadly forms of psychopathology. Despite decades of research, the roles of drug cues and craving in drug use and relapse remain controversial. Objective To assess whether 4 types of drug cue and craving indicators, including cue exposure, physiological cue reactivity, cue-induced craving, and self-reported craving (without cue exposure), are prospectively associated with drug use and relapse. Data Sources Google Scholar was searched for published studies from inception through December 31, 2018. In addition, backward and forward searches were performed on included articles to identify additional articles. Study Selection Included studies reported a prospective statistic that linked cue and craving indicators at time 1 to drug use or relapse at time 2, in humans. Data Extraction and Synthesis The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. Study characteristics and statistics were extracted and/or coded by 1 of the 2 authors and then checked by the other. Statistical analyses were performed from May to July 2021. Main Outcomes and Measures Random-effects models were used to calculate prospective odds ratios (ORs) representing the association between cue and craving indicators and subsequent drug use/relapse. Results A total of 18 205 records were identified, and 237 studies were included. Across 656 statistics, representing 51 788 human participants (21 216 with confirmed SUDs), a significant prospective association of all cue and craving indicators with drug use/relapse was found (OR, 2.05; 95% CI, 1.94-2.15), such that a 1-unit increase in cue and craving indicators was associated with more than double the odds of future drug use or relapse. A Rosenthal fail-safe analysis revealed that 180 092 null studies would need to be published to nullify this finding. Trim-and-fill analysis brought the adjusted effect size to an OR of 1.31 (95% CI, 1.25-1.38). Moderator analyses showed that some of the strongest associations were found for cue-induced craving, real cues or images, drug use outcome, same-day time lag, studies using ecological momentary assessment, and male participants. Conclusions and Relevance Findings from this systematic review and meta-analysis suggest that drug cue and craving indicators play significant roles in drug use and relapse outcomes and are an important mechanism underlying SUDs. Clinically, these results support incorporating craving assessment across stages of treatment, as early as primary care.

Abstract
BACKGROUND Dietary intake is a powerful modifiable factor that influences cancer risk; however, most US adults do not adhere to dietary guidelines for cancer prevention. One promising pathway for improving dietary adherence is targeting grocery shopping habits. Interventions might facilitate healthy grocery choices, with a combination of mHealth and traditional methods, by promoting the salience of dietary goals while shopping, enhancing motivation to make dietary changes, and increasing household support for healthy food purchasing. OBJECTIVE This pilot study will assess feasibility and acceptability of intervention components designed to improve adherence to dietary guidelines for cancer prevention (preliminary aim). The primary aim of the study is to quantify the effect of each intervention component, individually and in combination, on dietary intake (primary aim) and grocery store food purchases (exploratory aim). Mediation analyses will be conducted to understand the mechanisms of action (goal salience, motivation, and household support-secondary aims). The overarching goal is to optimize an mHealth intervention to be tested in a future fully powered clinical trial. METHODS The study enrolled adults (N=62) with low adherence to dietary recommendations for cancer prevention. In a 20-week program, all participants attend a nutrition education workshop and receive weekly educational messages through an app. A factorial design is used to test 4 intervention components: (1) location-triggered messages: educational messages are delivered when arriving at grocery stores; (2) reflections on the benefits of change: content is added to messages to encourage reflection on anticipated benefits of healthy eating, and participants attend an additional workshop session and 3 coach calls on this topic; (3) coach monitoring: food purchases are monitored digitally by a coach who sends personalized weekly app messages and conducts 3 coaching calls that focus on feedback about purchases; and (4) household support: another adult in the household receives messages designed to elicit support for healthy food purchasing, and support is addressed in 3 coach calls and an extra workshop session attended by the index participant and household member. Assessments are completed at weeks 0, 10, and 20 using self-report measures, as well as objective capture of grocery data from the point of purchase using store loyalty accounts. RESULTS The National Cancer Institute funded this study (R21CA252933) on July 7, 2020. Participant recruitment began in the spring of 2021 and concluded with the successful enrollment of 62 participants. Data collection is expected to be completed in the summer of 2022, and results are expected to be disseminated in the summer of 2023. CONCLUSIONS The results of this study will inform the development of scalable interventions to lower cancer risk via changes in dietary intake.

Abstract
Neural reactivity to food cues may play a central role in overeating and excess weight gain. Functional magnetic resonance imaging (fMRI) studies have implicated regions of the reward network in dysfunctional food cue-reactivity, but neural interactions underlying observed patterns of signal change remain poorly understood. Fifty overweight and obese participants with self-reported cue-induced food craving viewed food and neutral cues during fMRI scanning. Regions of the reward network with significantly greater food versus neutral cue-reactivity were used to specify plausible models of task-related neural interactions underlying the observed blood oxygenation level-dependent (BOLD) signal, and a bi-hemispheric winning model was identified in a dynamic causal modeling (DCM) framework. Neuro-behavioral correlations are investigated with group factor analysis (GFA) and Pearson’s correlation tests. The ventral tegmental area (VTA), amygdalae, and orbitofrontal cortices (OFC) showed significant food cue-reactivity. DCM suggests these activations are produced by largely reciprocal dynamic signaling between these regions, with food cues causing regional disinhibition and an apparent shifting of activity to the right amygdala. Intrinsic self-inhibition in the VTA and right amygdala is negatively correlated with measures of food craving and hunger and right-amygdalar disinhibition by food cues is associated with the intensity of cue-induced food craving, but no robust cross-unit latent factors were identified between the neural group and behavioral or demographic variable groups. Our results suggest a rich array of dynamic signals drive reward network cue-reactivity, with the amygdalae mediating much of the dynamic signaling between the VTA and OFCs. Neuro-behavioral correlations suggest particularly crucial roles for the VTA, right amygdala, and the right OFC-amygdala connection but the more robust GFA identified no cross-unit factors, so these correlations should be interpreted with caution. This investigation provides novel insights into dynamic circuit mechanisms with etiologic relevance to obesity, suggesting pathways in biomarker development and intervention.

Abstract
BACKGROUND Eating behaviors are determined by a complex interplay between behavioral and physiologic signaling occurring before, during, and after eating. OBJECTIVES The aim was to explore how selected behavioral and physiologic variables separately and grouped together predicted intake of 8 different foods. METHODS One hundred adults with normal weight performed a food preference task combined with biometric measurements (the Steno Biometric Food Preference Task) in the fasting state. The task measured food reward as well as biometric (eye tracking, electrodermal activity, and facial expressions) responses to images of foods varying in fat content and taste. Energy intake from an ad libitum buffet of the same 8 foods as assessed in the preference task was subsequently assessed. A mixed-effects random forest approach was applied to explore how individual and combined measures of food reward and biometric responses predicted energy intake of the 8 single foods. The performance of the different prediction models was compared with the predictions from a linear model including only an intercept (naïve model) using bootstrap cross-validation. RESULTS Participants had a median [IQR] intake of 369 kJ [126-472 kJ] per food. Combined or separate measures of food reward or biometric responses did not predict energy intake better than the naïve model. CONCLUSIONS We did not find that the reward or biometric responses to food cues assessed in a clinical setting were useful in predicting energy intake of single foods. However, this study provides a framework in the field of behavioral nutrition for applying machine learning with a focus on individual predictions. This is necessary on the road toward personalized nutrition and provides great potential for handling complex data with multiple variables.This trial was registered at clinicaltrials.gov as NCT03986619.

Abstract
Background Eating plays an important role in mental and physical health and is influenced by affective (e.g., emotions, stress) and appetitive (i.e., food craving, hunger) states, among others. Yet, substantial temporal variability and marked individual differences in these relationships have been reported. Exploratory data analytical approaches that account for variability between and within individuals might benefit respective theory development and subsequent confirmatory studies. Methods Across 2 weeks, 115 individuals (83% female) reported on momentary affective states, hunger, and food craving six times a day. Based on these ecological momentary assessment (EMA) data we investigated whether latent class vector-autoregression (LCVAR) can identify different clusters of participants based on similarities in their temporal associations between these states. Results LCVAR allocated participants into three distinct clusters. Within clusters, we found both positive and negative associations between affective states and hunger/food craving, which further varied temporally across lags. Associations between hunger/food craving and subsequent affective states were more pronounced than vice versa. Clusters differed on eating-related traits such as stress-eating and food craving as well as on EMA completion rates. Discussion LCVAR provides novel opportunities to analyse time-series data in affective science and eating behaviour research and uncovers that traditional models of affect-eating relationships might be overly simplistic. Temporal associations differ between subgroups of individuals with specific links to eating-related traits. Moreover, even within subgroups, differences in associations across time and specific affective states can be observed. To account for this high degree of variability, future research and theories should consider individual differences in direction and time lag of associations between affective states and eating behaviour, daytime and specific affective states. In addition to that, methodological implications for EMA research are discussed. Supplementary Information The online version contains supplementary material available at 10.1186/s12966-022-01293-1.

So BPH, Lai DKH, Cheung DSK, Lam WK, Cheung JCW, Wong DWC. Virtual Reality-Based Immersive Rehabilitation for Cognitive- and Behavioral-Impairment-Related Eating Disorders: A VREHAB Framework Scoping Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19105821. [PMID: 35627357 PMCID: PMC9141870 DOI: 10.3390/ijerph19105821] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 05/07/2022] [Accepted: 05/09/2022] [Indexed: 11/16/2022]
Abstract
Virtual reality (VR) technology is one of the promising directions for rehabilitation, especially cognitive rehabilitation. Previous studies demonstrated successful rehabilitation in motor, cognitive, and sensorial functions using VR. The objective of this review is to summarize the current designs and evidence on immersive rehabilitation interventions using VR on cognitive- or behavioral-related eating disorders, which was mapped using a VREHAB framework. Two authors independently searched electronic databases, including PubMed, Web of Science, Scopus, CINAHL, EMBASE, and Cochrane Library. Ten (n = 10) articles were eligible for review. Treatments for anorexia nervosa and binge eating disorder/bulimia nervosa were reported through enhanced/experimental cognitive behavior therapy (ECT), cue exposure therapy (CET), and body exposure therapy (BET) via the virtual environment. Some studies reported that the VR effects were superior or comparable to traditional treatments, while the effects may last longer using VR technology. In addition, VR was perceived as acceptable and feasible among patients and therapists and could be valuable for supplementing existing therapies, relieving manpower and caregiver burdens. Future studies may consider incorporating haptic, smell, and biofeedback to improve the experience, and thus the effects of the treatments for the users.

Abstract
Addictive-like eating is prevalent, but a clear conceptualization and operationalization outside of an addiction framework is lacking. By adopting a biopsychological framework of food reward, this study sought to develop and evaluate a brief self-report questionnaire for the trait assessment of hedonic overeating and dyscontrol. Items in the Hedonic Overeating–Questionnaire (HEDO–Q) were constructed following a rational approach and psychometrically evaluated in a large random sample from the German population (N = 2531). A confirmatory factor analysis supported the unidimensional nature of the six-item HEDO–Q with the three postulated components of wanting, liking, and dyscontrol. Psychometric properties were favorable with good corrected item-total correlations, acceptable item difficulty and homogeneity, and high internal consistency. Population norms were provided. The HEDO–Q revealed strict measurement invariance for sex and partial invariance for age and weight status. Discriminant validity was demonstrated in distinguishing participants with versus without eating disturbances or obesity. Associations with the established measures of eating disorder and general psychopathology supported the convergent and divergent validity of the HEDO–Q. This first evaluation indicates good psychometric properties of the HEDO–Q in the general population. Future validation work is warranted on the HEDO–Q’s stability, sensitivity to change, and predictive and construct validity.

Abstract
BACKGROUND The East Asia region is facing an increasing burden of overweight, obesity and related noncommunicable diseases, resulting from an ongoing nutrition transition. This study aimed to document the growing burden of overweight and obesity, and the accompanying dietary shifts, in the East Asia region and describe the policy responses to this. METHODS We present noncommunicable disease risk factor collaboration data on trends in the burden of malnutrition, and Euromonitor International data on trends in dietary purchases, in the East Asia region. We searched the NOURISHING and GINA databases to identify food and nutrition policies implemented in these countries. RESULTS There is an ongoing nutrition transition in the East Asia region, notably in upper-middle and lower-middle income countries. The prevalence of overweight, obesity, and accompanying health conditions, purchases of ultra-processed foods and beverages, and purchasing from supermarkets, fast-food and takeaway outlets, and other convenience retailers, are increasing. The policy response to this nutrition transition is limited, with the majority of policies implemented in higher-income countries. CONCLUSIONS East Asian countries are facing a growing burden of malnutrition, due in part to the dietary shifts occurring here. An ecological approach to policy intervention is needed to drive transformative food systems change.

Abstract
OBJECTIVE Theories on emotional eating are central to our understanding of etiology, maintenance, and treatment of binge eating. Yet, findings on eating changes under induced negative emotions in binge-eating disorder (BED) are equivocal. Thus, we studied whether food-cue reactivity is potentiated under negative emotions in BED, which would point toward a causal role of emotional eating in this disorder. METHODS Patients with BED (n = 24) and a control group without eating disorders (CG; n = 69) completed a food picture reactivity task after induction of negative versus neutral emotions. Food-cue reactivity (self-reported food pleasantness, desire to eat [DTE], and corrugator supercilii muscle response, electromyogram [EMG]) was measured for low- and high-caloric food pictures. RESULTS Patients with BED showed emotion-potentiated food-cue reactivity compared to controls: Pleasantness and DTE ratings and EMG response were increased in BED during negative emotions. This was independent of caloric content of the images. CONCLUSIONS Food-cue reactivity in BED was consistent with emotional eating theories and points to a heightened response to all foods regardless of calorie content. The discrepancy of appetitive ratings with the aversive corrugator response points to ambivalent food responses under negative emotions in individuals with BED.

Abstract
BACKGROUND This trial examined the feasibility, acceptability, and effect sizes of clinical outcomes of an intervention that combines inhibitory control training (ICT) and implementation intentions (if-then planning) to target binge eating and eating disorder psychopathology. METHODS Seventy-eight adult participants with bulimia nervosa or binge eating disorder were randomly allocated to receive food-specific, or general, ICT and if-then planning for 4 weeks. RESULTS Recruitment and retention rates at 4 weeks (97.5% and 79.5%, respectively) met the pre-set cut-offs. The pre-set adherence to the intervention was met for the ICT sessions (84.6%), but not for if-then planning (53.4%). Binge eating frequency and eating disorder psychopathology decreased in both intervention groups at post-intervention (4 weeks) and follow-up (8 weeks), with moderate to large effect sizes. There was a tendency for greater reductions in binge eating frequency and eating disorders psychopathology (i.e. larger effect sizes) in the food-specific intervention group. Across both groups, ICT and if-then planning were associated with small-to-moderate reductions in high energy-dense food valuation (post-intervention), food approach (post-intervention and follow-up), anxiety (follow-up), and depression (follow-up). Participants indicated that both interventions were acceptable. CONCLUSIONS The study findings reveal that combined ICT and if-then planning is associated with reductions in binge eating frequency and eating disorder psychopathology and that the feasibility of ICT is promising, while improvements to if-then planning condition may be needed.

Short Video Viewing, and Not Sedentary Time, Is Associated with Overweightness/Obesity among Chinese Women. Nutrients 2022; 14:nu14061309.

Abstract
Previous studies have found that the relationship between sedentary time (ST) and overweightness/obesity is unclear. The association between sedentary behavior and overweightness/obesity may depend on the type of sedentary behavior engaged in. Nowadays, in older Chinese adults, especially females, short video viewing (SVV) is the most popular leisure sedentary behavior. However, the association between SVV and overweightness/obesity remains to be determined. This study aimed to examine the associations between ST and SVV and overweightness/obesity in Chinese community-dwelling older women. A cross-sectional analysis of baseline data from the Physical Activity and Health in Older Women Study was carried out in this study. A total of 1105 older Chinese women aged 60–70 years were included. SVV was estimated using a self-reported questionnaire, and ST was objectively measured using a tri-axial accelerometer. Overweightness/obesity indicators, including body fat ratio (BFR), fat mass (FM), visceral fat mass (VFM), subcutaneous fat mass (SFM), trunk fat mass (TFM), and limb fat mass (LFM), were assessed using multi-frequency bioimpedance analysis. The covariates included socio-demographic data and a range of health-related factors. Multiple linear regression analyses were used to assess the association between ST and SVV and overweightness/obesity. ST was significantly positively associated with all indicators of overweightness/obesity; however, the associations disappeared after adjusting for moderate-to-vigorous-intensity physical activity (MVPA). A higher SVV time was associated with a higher body mass index (BMI) (β = 0.19, 95% confidence interval (CI): 0.05 to 0.32), BFR (β = 0.31, 95% CI: 0.07 to 0.56), FM (β = 0.33, 95% CI: 0.04 to 0.61), VFM (β = 0.09, 95% CI: 0.01 to 0.16), SFM (β = 0.24, 95% CI: 0.03 to 0.45), TFM (β = 0.21, 95% CI: 0.04 to 0.39), and LFM (β = 0.11, 95% CI: 0.00 to 0.23) in the fully adjusted models. Compared with non-food short videos, short food videos had a greater effect on overweightness/obesity. SVV was an independent risk factor for overweightness/obesity. A reduction in SVV (especially the food category) rather than ST might be an effective way to prevent overweightness/obesity when incorporated in future public health policy formulations.

Abstract
Smell plays a critical role in food choice and intake by influencing energy balance and body weight. Malnutrition problems or modified eating behaviors have been associated with olfactory impairment or loss. The obesity epidemic is a serious health problem associated with an increased risk of mortality and major physical comorbidities. The etiopathogenesis of obesity is complex and multifactorial, and one of the main factors contributing to the rapid increase in its incidence is the environment in which we live, which encourages the overconsumption of foods rich in energy, such as saturated fats and sugars. By means of the “Sniffin’ Sticks” test, we measured the olfactory threshold, discrimination and identification score (TDI score) in patients of the Obesity Center of the University Hospital (OC; n = 70) and we compared them with that of healthy normal weight controls (HC; n = 65). OC patients demonstrated a significantly lower olfactory function than HC subjects both general and specific for the ability to discriminate and identify odors, even when they were considered separately as females and males. For OC patients, a negative correlation was found between body mass index (BMI) and olfactory scores obtained by each subject, both when they were divided according to gender and when they were considered all together. Besides, normosmic OC patients showed a significantly lower BMI than hyposmic ones. A reduced sense of smell may contribute to obesity involving the responses of the cephalic phase, with a delay in the achievement of satiety and an excessive intake of high-energy foods and drinks.

Abstract
Recent meta-analyses have shown that psychological interventions have a small to medium effect on weight loss. We propose here a different approach to changing eating intentions. According to the Free Will literature, people decide to act before they acknowledge it, and they decide based on the reconstruction of previous experiences. The action can thus be inhibited immediately (max 100 ms) after awareness. We wanted to test if intervention based on this model, using hypnotic suggestions, can effectively change the intentions of eating. This study aims to identify which format of hypnotic suggestion can be more effective in changing eating intentions regarding high-calorie foods. Therefore, 88 healthy adult participants randomized in four groups received one session of hypnotic induction and suggestions or placebo. We measured the eating intentions through a computer task in which participants could choose pictures of low and high caloric food before, during, and after hypnosis. For the within-subject effect, results showed that two types of hypnotic suggestions significantly impacted the intentions of eating on high-calorie foods with large-effect, namely Cognitive Rehearsal (d = 0.81, p < .001) and Memory Substitution (d = 0.82, p < .001). After controlling for pretest ratings, we found a significant between-effect: the Cognitive Rehearsal group differed significantly from the Control in terms of intentions of eating (d = 0.85, p < .05). We conclude that hypnosis with Cognitive Rehearsal suggestions can help to positively impact the intentions of eating.

Abstract
AIMS We investigated if individuals with higher emotional eating scores are less sensitive to the effects of a GLP-1RA on central responses to food cues. Additionally, we investigated the associations of higher external and restraint eating scores with the sensitivity to the central effects of GLP-1RA. METHODS This secondary analysis of a randomized crossover study in people with obesity and type 2 diabetes, consisted of two periods of 12-week treatment with liraglutide or insulin glargine. Using functional MRI, we assessed the relation between baseline eating behavior and the effects of the GLP-1RA liraglutide compared with insulin after 10 days and 12 weeks of treatment on brain responses to food cues. RESULTS After 10 days, higher emotional eating scores were associated with less pronounced GLP-1RA induced reductions in brain responses to food pictures in the amygdala, insula and caudate nucleus. In addition, higher emotional eating scores tended to be associated with less pronounced GLP-1RA increases in brain responses to chocolate milk receipt in the caudate nucleus and insula. After 12 weeks, there were no significant associations between emotional eating scores and liraglutide-induced changes in brain responses to food cues. After 10 days, baseline external eating scores were associated with less pronounced GLP-1RA induced reductions in brain responses to food pictures in the insula, amygdala and orbitofrontal cortex. After 12 weeks, baseline restraint eating scores were associated with more GLP-1RA induced reductions in brain responses to food pictures in the insula and caudate nucleus, and with more GLP-1RA induced reductions in brain responses to the anticipation of chocolate milk in the caudate nucleus. CONCLUSIONS Our findings indicate that individuals with higher baseline emotional eating scores are less sensitive to the central effect of GLP-1RA treatment. Additionally, external eating may also decrease, whereas restraint eating may increase the sensitivity to the treatment effects of GLP-1RAs. These insights may help to optimize treatment strategies for obesity and to select patient groups with better efficacy of GLP-1RA treatment.

Abstract
A person can alternate between food-related mindsets, which in turn may depend on one's emotional state or situation. Being in a certain mindset can influence food-related thoughts, but interestingly it might also affect eating-related physiological responses. The current study investigates the influence of an induced 'loss of control' mindset as compared to an 'in control' mindset on hormonal, neural and behavioural responses to chocolate stimuli. Mindsets were induced by having female chocolate lovers view a short movie during two sessions in a within-subjects design. Neural responses to visual chocolate stimuli were measured using an ultra-high field (7T) scanner. Momentary ghrelin and glucagon-like peptide 1 (GLP-1) levels were determined on five moments and were simultaneously assessed with self-reports on perceptions of chocolate craving, hunger and feelings of control. Furthermore, chocolate intake was measured using a bogus chocolate taste test. It was hypothesized that the loss of control mindset would lead to hormonal, neural and behavioural responses that prepare for ongoing food intake, even after eating, while the control mindset would lead to responses reflecting satiety. Results show that neural activity in the mesocorticolimbic system was stronger for chocolate stimuli than for neutral stimuli and that ghrelin and GLP-1 levels responded to food intake, irrespective of mindset. Self-reported craving and actual chocolate intake were affected by mindset, in that cravings and intake were higher with a loss of control mindset than with a control mindset. Interestingly, these findings suggest that physiology on the one hand (hormonal and neural responses) and behavior and subjective experience (food intake and craving) on the other hand are not in sync, are not equally affected by mindset.

Modulating eating behavior with transcranial direct current stimulation (tDCS): A systematic literature review on the impact of eating behavior traits. Obes Rev 2022; 23:e13364.

Abstract
Transcranial direct current stimulation (tDCS) is becoming an increasingly popular technique for altering eating behaviors. Recent research suggests a possible eating behavior trait-dependent effect of tDCS. However, studies recruit participant populations with heterogeneous trait characteristics, including "healthy" individuals who do not present with eating behavior traits suggesting susceptibility to overconsumption. The present review considers the effects of tDCS across eating-related measures and explores whether a trait-dependent effect is evident across the literature. A literature search identified 28 articles using sham-controlled tDCS to modify eating-related measures. Random effects meta-analyses were performed, with subgroup analyses to identify differences between "healthy" and trait groups. Trivial overall effects (g = -0.12 to 0.09) of active versus sham tDCS were found. Subgroup analyses showed a more consistent effect for trait groups, with small and moderate effect size (g = -1.03 to 0.60), suggesting tDCS is dependent on participants' eating behavior traits. Larger effect sizes were found for those displaying traits associated with study outcomes (e.g., heightened food cravings). "Healthy" individuals appear to be unresponsive to stimulation. Based on this meta data, future work should recruit those with eating behavior trait susceptibilities to overconsumption, focusing on those who present with traits associated with the outcome of interest.

Abstract
BACKGROUND Inconsistent sleep patterns may promote excess weight gain by increasing food cravings and loss-of-control (LOC)-eating; however, these relationships have not been elucidated in youth. OBJECTIVE We tested whether sleep duration and timing were associated with food cravings and LOC-eating. METHOD For 14 days, youths wore actigraphy monitors to assess sleep and reported severity of food cravings and LOC-eating using ecological momentary assessment. Generalized linear mixed models tested the associations between weekly and nightly shifts in facets of sleep (i.e., duration, onset, midpoint, and waketime) and next-day food cravings and LOC-eating. Models were re-run adjusting for relevant covariates (e.g., age, sex, adiposity). RESULTS Among 48 youths (12.88 ± 2.69 years, 68.8% female, 33.3% with overweight/obesity), neither weekly nor nightly facets of sleep were significantly associated with food cravings (ps = 0.08-0.93). Youths with shorter weekly sleep duration (est. ß = -0.31, p = 0.004), earlier weekly midpoints (est. ß = -0.47, p = 0.010) and later weekly waketimes (est. ß = 0.49, p = 0.010) reported greater LOC-eating severity; findings persisted in adjusted models. CONCLUSIONS In youth, weekly, but not nightly, shifts in multiple facets of sleep were associated with LOC-eating severity; associations were not significant for food cravings. Sleep should be assessed as a potentially modifiable target in paediatric LOC-eating and obesity prevention programs.

Abstract
OBJECTIVE Literature on food marketing targeting young people reveals that in the last years, sophisticated marketing techniques have been developed to market predominantly unhealthy food products. Much research has been conducted to test the impact of these techniques on subsequent product selection and intake. Less is known about the effects of promoting healthier foods, although the health-related benefits of eating more fruit and vegetables for children are important. The main aim of the present experiment was to examine if an online advergame promoting a fruit brand with food products increased subsequent fruit intake by children. METHODS We used a randomized between-subject design with 123 children (age: 7-13 years) who played an advergame that promoted fruit (n = 43), non-food products (n = 40), or were in the control condition (n = 40). Subsequently, we measured the free intake of fruit as main outcome. RESULTS Playing the advergame promoting fruit did not stimulate the subsequent intake of fruit. Children in the advergame with fruit ate similar amounts of fruit than children in the control condition. No moderation effects of BMI, hunger, sex and game attitude were found. In addition, Bayesian analyses have been conducted that support the null hypothesis. DISCUSSION Previous research has shown that marketing of unhealthy products via advergames affects subsequent intake of the promoted product, but the same effect is not found for healthier foods. We suggest that future research should examine if longer exposure or different forms of novel food marketing are effective in increasing the intake of healthier foods. Until now, it is unclear if advergames as a marketing technique for healthy foods have the same effectiveness on the intake of healthier food products.

Abstract
Nowadays people use screens, such as mobile phones, television, or tablets, more often during mealtimes, which may have an effect on intake. This review aims to analyze the effect of screen use, during food consumption, on intake. A systematic review was carried out, based on those protocols established by PRISMA. The Cochrane Library, PubMed, Web of Science and Scopus databases were consulted. Experimental studies, published between 2010 and 2021, that recorded individual intake while using screens such as television, cell phones, or tablets, were selected. A total of 7181 relevant articles were obtained, which were then assessed in accordance with predetermined inclusion and exclusion criteria. Finally, 35 studies were included in the complete review: 22 compared different kinds of television content (e.g., adverts), five which compared television versus the absence of screens, four which compared television versus video games, two which compared the use of simultaneous screens, and two studies which included cell phones. A total of 27 studies reported consumption increases related to the presence of advertisements and food signals on screens. No significant differences in intake were reported in the eight studies that reported design or sample size limitations, or lack of control of certain variables. It is thus concluded that screen use during food consumption may increase intake. Education is necessary to regulate the habit of consuming food in the presence of screens. Also, the creation of policies that regulate advertising and food cues on screens are justified and must be accompanied by strategies to monitor compliance. As a limitation, further evidence is necessary in order to determine the effect of mobile phone and tablet use while eating. This protocol was registered via PROSPERO, ID: CRD42020211797.

An implicit priming intervention alters brain and behavioral responses to high-calorie foods: a randomized controlled study. Am J Clin Nutr 2022; 115:1194-1204.

Abstract
BACKGROUND Conditioned food cues (e.g., smell, sight) can affect intake of foods associated with those cues, regardless of homeostatic need. As such, altering automatic associations with food cues could support weight loss or maintenance efforts by affecting the salience of those cues and the effort required to resist consumption. OBJECTIVES This study investigated neuronal and behavioral effects of an implicit priming (IP) intervention, in which negatively valenced images were paired with high-calorie foods and positively valenced images with low-calorie foods. Priming images were presented immediately before food images, but below conscious perception (20 ms). We hypothesized that this evaluative conditioning approach could alter food cue responses by modifying affective associations. METHODS The final sample included 41 adults with BMI ≥25 kg/m2 (n = 22, active IP; n = 19, control IP). In control IP, food images were primed with neutral, scrambled images. Participants completed a visual food cue task during fMRI, both before and after IP. To determine the replicability of prior behavioral findings, food image ratings were completed before and after IP as a secondary outcome. RESULTS In a whole-brain analysis, reduced dorsolateral prefrontal cortex (dlPFC) response to high-calorie foods was observed after active compared with control IP (t = 4.93, P = 0.033). With a region of interest analysis, reduced response to high-calorie foods in active compared with control IP was also observed in the striatum (t = 2.40, P = 0.009) and insula (t = 2.38, P = 0.010). Active compared with control IP was associated with reduced high-calorie food ratings (F = 4.70, P = 0.038). CONCLUSIONS Reduced insula and striatum response to high-calorie foods after active compared with control IP suggests effectiveness of IP in altering food cue salience. Reduced dlPFC response to high-calorie foods after active compared with control IP may reflect fewer attentional resources being directed to those images and reduced engagement of inhibitory processes.This trial was registered at clinicaltrials.gov as NCT02347527.

Abstract
Growing evidence suggests that relative disadvantage is more relevant than absolute socioeconomic factors in explaining disparities in healthfulness of diet. In a series of pre-registered experiments, we tested whether personal relative deprivation (PRD), i.e. the sense that one is unfairly deprived of a deserved outcome relative to others, results in choosing more palatable, rewarding foods. Study 1 (N = 102) demonstrated the feasibility and effectiveness of a game for inducing real-time experiences of PRD. Study 2 (N = 287) showed no main effect of PRD condition on hypothetical food choices, but an interaction between chronic PRD and condition revealed that those in the PRD condition chose more rewarding foods when feeling chronically deprived. In Study 3 (N = 260) the hypothesized main effect was found on real, non-hypothetical food choices: those in the PRD condition chose more rewarding foods, controlling for sensitivity to palatable food. Our results provide preliminary indications that the experience of being relatively deprived, rather than the objective amount or resources, may result in a higher preference for high-caloric and palatable foods. It may be suggested that efforts to reduce societal disparities in healthfulness of diet may need to focus on perceptions of injustice beyond objective inequalities.

Abstract
OBJECTIVE To quantify the extent of food and beverage advertising on bus shelters in a deprived area of the UK, to identify the healthfulness of advertised products, and any differences by level of deprivation. The study also sought to assess the creative strategies used and extent of appeal to young people. DESIGN Images of bus shelter advertisements were collected via in person photography (in 2019) and Google Street View (photos recorded in 2018). Food and beverage advertisements were grouped into one of seventeen food categories and classified as healthy/less healthy using the UK Nutrient Profile Model. The deprivation level of the advertisement location was identified using the UK Index of Multiple Deprivation. SETTING Middlesbrough and Redcar and Cleveland in South Teesside. PARTICIPANTS N/A. RESULTS Eight hundred and thirty-two advertisements were identified, almost half (48·9 %) of which were for foods or beverages. Of food and non-alcoholic beverage adverts, 35·1 % were less healthy. Most food advertisements (98·9 %) used at least one of the persuasive creative strategies. Food advertisements were found to be of appeal to children under 18 years of age (71·9 %). No differences in healthiness of advertised foods were found by level of deprivation. CONCLUSIONS Food advertising is extensive on bus shelters in parts of the UK, and a substantial proportion of this advertising is classified as less healthy and would not be permitted to be advertised around television programming for children. Bus shelter advertising should be considered part of the UK policy deliberations around restricting less healthy food marketing exposure.

Abstract
Cue reactivity to Electronic Nicotine Delivery Systems (ENDS) has been studied by several researchers, yet the variability in user types (smokers, former smokers, dual users, exclusive ENDS users) and ENDS designs used between the studies may have undermined consistent results. This systematic review aims to give an overview of ENDS cue reactivity and how smoking status and device design may moderate this. A systematic search of Medline, Embase, Web of Science, PubMed and Cochrane was completed. All studies which reported findings on reactivity to ENDS cues in the form of craving or desire for ENDS or cigarettes, attention to cue, delay of gratification or economic decisions were included. Exclusion criteria were non-human subjects, non-adult participants or participants with comorbidities. Literature selection was carried out by 2 independent reviewers. The risk of bias and study quality were assessed using tools developed by Cochrane, BMJ and NHLBI. A total of 711 papers were screened and 22 studies were included in the current review. Study design, research question(s), population of interest, number of participants, dependent variable(s), ENDS generation and nicotine content used and study results were extracted. ENDS cues reliably induced ENDS craving, with no clear moderation by smoking status and no apparent moderation by device generation. In about half of the studies, ENDS cues induced craving for conventional cigarettes. Most studies used a smoker sample, thus limiting the conclusions that can be drawn on the moderation of cue reactivity by smoking status. The quality varied among studies but comparing the findings against the outcomes of only high-quality studies did not yield any different results. The results of this review support the notion of cue reactivity to ENDS, identifies gaps in current research on different user types and implies that ENDS design iterations have little impact on cue reactivity.

Burmester V, Butler GK, Terry P. Intranasal oxytocin reduces attentional bias to food stimuli. Appetite 2022; 168:105684. [PMID: 34496275 DOI: 10.1016/j.appet.2021.105684] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 08/24/2021] [Accepted: 09/04/2021] [Indexed: 11/28/2022]
Abstract
Attentional biases to food-related stimuli have been demonstrated in response to hunger as well as during restrained eating. Such biases are often associated with obesity, but healthy-weight individuals who do not self-report hunger have also demonstrated attentional biases to stimuli signalling food using laboratory-based cognitive tasks. Levels of the anorectic neuropeptide oxytocin are elevated by food intake and, when administered intranasally, oxytocin inhibits food intake in the laboratory. To investigate whether oxytocin can affect appetite via an action on attentional processes, 40 adults (29 women; mean age 24.0 years old) self-administered 24 IU of oxytocin or placebo intranasally. Forty minutes after administration, participants ate a small snack to maintain alertness and ameliorate deprivation-induced hunger before starting a computerized dot-probe attentional bias task that presented 180 trials of paired visual stimuli comprising neutral, food, social and/or romantic images (500 ms presentation time). Reaction times to probe stimuli that appeared after the offset of the visual images indicated a significant attentional bias to food pictures after placebo; this effect was significantly attenuated by oxytocin, p < .001. The effect of oxytocin on attentional bias to the food pictures was not altered by the type of stimulus paired with the food image, and was independent of BMI, age, sex, self-rated eating behaviour, and self-reported parental bonding; however, the effect was modulated by self-reported food cravings and trait stress. The findings support and extend previous work which has suggested that oxytocin can counteract attentional biases to food-related stimuli in a sample with anorexia by demonstrating the same effect for the first time in a cohort who do not have an eating disorder.

Abstract
Obesity negatively impacts patients' health-related quality of life (QOL) and is associated with a range of complications such as type 2 diabetes (T2D), cardiovascular disease, and sleep apnea, alongside decreased physical function, mobility, and control of eating. The Semaglutide Treatment Effect in People with obesity (STEP) trials compared once-weekly subcutaneous semaglutide 2.4 mg with placebo in adults with overweight or obesity, with or without T2D. This article reviews the effects of semaglutide 2.4 mg on QOL, control of eating, and body composition. Weight-related QOL was assessed using the Impact of Weight on Quality of Life-Lite Clinical Trials Version (IWQOL-Lite-CT), and health-related QOL was assessed with the 36-item Short Form Health Survey version 2 (SF-36v2®). Control of eating was evaluated using the Control of Eating questionnaire in a subgroup of participants in one trial. Body composition was evaluated via dual-energy x-ray absorptiometry in another trial, in a subgroup of participants with a body mass index of ≤40 kg/m2. All IWQOL-Lite-CT scores (Physical Function, Physical, Psychosocial, and Total Score) improved with semaglutide 2.4 mg significantly more than with placebo. Across the trials, changes in SF-36v2 scores were generally in favor of semaglutide versus placebo. There were significant improvements in all Control of Eating questionnaire domains (craving control, craving for savory, craving for sweet, and positive mood) up to week 52 with semaglutide treatment versus placebo, with improvements in craving control and craving for savory remaining significantly different at week 104. Body composition findings showed that reductions in total fat mass were greater with semaglutide versus placebo. These findings highlight the wider benefits that patients can experience with once-weekly subcutaneous semaglutide 2.4 mg, in addition to weight loss, including improvements in patients' wellbeing and ability to perform daily activities. Taken together, these are important considerations for primary care when incorporating pharmacotherapy for weight management.

External food cue responsiveness and emotional eating in adolescents: A multimethod study. Appetite 2022; 168:105789. [PMID: 34728251 PMCID: PMC8671220 DOI: 10.1016/j.appet.2021.105789] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2021] [Revised: 10/18/2021] [Accepted: 10/29/2021] [Indexed: 01/03/2023]
Abstract
Eating in response to external food cues (i.e., external eating) and internal emotional experiences (i.e., emotional eating) are associated with obesity. While external and emotional eating co-occur, little is known about how external food cue responsiveness may interact with internal emotional cues to influence eating episodes in adolescents. The current study examined how trait-level external food cue responsiveness modulates momentary associations between affective states and eating in adolescents. Participants were drawn from a prior study of siblings (N = 78; ages 13-17) who completed an ecological momentary assessment protocol to assess eating episodes and affective states. External food cue responsiveness was determined by comparing energy consumption following presentation of an appetizing food (pizza) on one day and a control activity (reading) on another day. Generalized linear mixed models examined positive and negative affective states, cue responsiveness, and their interactions as predictors of the likelihood of eating. The relationship between affective states and likelihood of eating was stronger among adolescents with higher versus lower external food cue responsiveness. Among adolescents with higher cue responsiveness, endorsing negative affect was associated with a lower likelihood of eating, whereas endorsing positive affect was associated with a higher likelihood of eating (within-person effects). Findings suggest that high sensitivity to external food cues and greater proclivity for emotional eating may be likely to coincide such that any cue, internal or external, is likely to disrupt sensitivity to internal hunger and satiety signals. Future studies are needed to elucidate how sensitivities to internal and external cues may interact to influence obesity risk.
