Evaluation of the relationships between dietary restraint, emotional eating, and intuitive eating moderated by sex

A systematic review of observational studies exploring the relationship between health and non-weight-centric eating behaviours

Eating behaviour that does not centralise weight, otherwise known as weight-neutral, is associated with improved physical and psychological health, and greater health promoting behaviours. However, consolidated evidence is lacking. This study aimed to systematically evaluate 'health-centric' eating behaviour reflective of weight-neutral approaches, and their relationship with health (physical and mental) and health promoting behaviours. A systematic search was performed, identifying observational studies with adult populations, ≥1 physical/mental health outcome(s), and ≥1 validated measure(s) of health-centric eating behaviour. Study design, sample characteristics and outcomes were extracted and characterised into four domains. Our search identified 8281 records, with 86 studies, 75 unique datasets, and 78 unique exposures including 94,710 individuals. Eating behaviours included intuitive eating (n = 48), mindful eating (n = 19), and eating competence (n = 11). There were 298 outcomes identified for body composition, size, and physical health (n = 116), mental health and wellbeing (n = 123), health promoting behaviours (n = 51) and other eating behaviour (n = 8). Higher levels of intuitive eating, mindful eating and eating competence were significantly related to a lower BMI, better diet quality and greater physical activity. Higher intuitive and mindful eating were significantly related to lower levels of disordered eating, and depressive symptoms, and greater body image, self-compassion, and mindfulness. Greater eating competence and intuitive eating were significantly related to higher fruit and vegetable intake, and greater eating competence to higher fibre intake and better sleep quality. Our results demonstrate that 'health-centric' eating behaviours are related to a range of favourable health outcomes and engagement in health promoting behaviours. These findings help to enhance our understanding of eating behaviours that do not centre around body weight, providing support for health-centric eating behaviour in healthcare. Future research should focus on intervention studies and more diverse population groups.

Body image, eating distress and emotional-behavioral difficulties among adolescents in Mbarara, Southwestern Uganda

BACKGROUND

Adolescents frequently have emotional and behavioral difficulties as they struggle with the challenges of transition from childhood to adulthood. Many struggle with issues of body image and eating distress as they deal with the difficult and frequently perplexing changes that occur with puberty. Yet there is surprisingly little research on the emotional and behavioral challenges, as well as body image and eating distress among this sizable population in Uganda. This study sought to assess attitudes and behaviors related to body image and eating distress, as well as emotional and behavioral difficulties among adolescents in Mbarara, Southwestern Uganda.

METHODS

This was a cross-sectional study among 788 adolescents aged 13 to 19 years in secondary schools in Mbarara city and Mbarara district in south-western Uganda. The study employed the Body Image and Eating Distress scale to assess attitudes and behaviors about dieting and body shape and the extended version of the Strengths and Difficulties Questionnaire (SDQ) to assess for perceived emotional and behavioral difficulties. Logistic regression was used to identify the association between body image and eating distress and perceived difficulties.

RESULTS

The prevalence of high body image and eating distress was 10.8% while that of perceived emotional and behavioral difficulties was 45.8%. Some of the adolescents (16.1%) were dissatisfied with their body shape, 24.6% exercised a lot to avoid gaining weight, 15.0% were terrified to gain even a little weight, and 12.1% could not control their eating. More males reported eating large amounts of food at one time (p =  < 0.001). Having emotional and behavioral difficulties (aOR: 1.89; 95% CI: 1.18 - 3.02; p = 0.019) and coming from a two-parent household (aOR: 1.79; 95% CI: 1.10 - 2.92; p = 0.019) increased the odds of high body image and eating distress.

CONCLUSION

High levels of body image and eating distress are linked to behavioral and emotional problems and adolescent's family structure. Clinicians who treat adolescents should use a holistic care strategy and be aware of the high prevalence and close association between emotional and behavioral difficulties, concerns about weight, and dieting. It is important to encourage parental involvement and support in providing information about mental health issues among adolescents.

Explaining the prospective paths from body appreciation to intuitive eating facets: Does body image flexibility serve as a mediator?

Initial evidence suggests that body appreciation prospectively predicts intuitive eating. However, the limited number of longitudinal studies focused solely on girls and women, with a lack of evaluation among men. Furthermore, the underlying mechanisms explaining this relationship remain poorly understood. The present study examined whether body appreciation prospectively predicted intuitive eating facets among women and men in Germany. We also tested whether adaptive affect regulation skills (i.e., body image flexibility) mediated these relationships. We analyzed data from 1436 women and 704 men across three time points: Baseline (T1), 6-month (T2), and 12-month (T3) follow-up, using latent variable path models to assess direct and indirect effects. Among women, T1 body appreciation directly predicted T3 body-food choice congruence. Additionally, body appreciation indirectly predicted unconditional permission to eat, eating for physical rather than emotional reasons, and reliance on hunger and satiety cues at T3 via its effect on T2 body image flexibility. Among men, T1 body appreciation indirectly predicted T3 eating for physical rather than emotional reasons via T2 body image flexibility. Our findings suggest that body image flexibility plays a pivotal role in explaining why individuals who appreciate their bodies are more likely to eat intuitively.

Emotional Eating among College Students in Israel: A Study during Times of War

Emotional eating, the act of consuming food to cope with negative emotions rather than responding to hunger cues, can lead to overeating in an attempt to regulate and alleviate these emotions. This study aimed to assess emotional eating among college students in Israel, specifically during times of war, which present unique and heightened stressors that accumulate on top. A total of 575 participants from the Ashkelon Academic College completed an online questionnaire examining background information, stress levels, and emotional eating symptoms. Our findings indicate that factors, such as being female, not having children, younger age, lower body satisfaction, higher BMI, and increased stress, are predictors of heightened emotional eating. These results highlight risk factors predisposing college students to engage in emotional eating. Developing targeted interventions, particularly campus-based programs to address emotional eating by promoting healthy coping strategies, a positive body image, and stress management skills is needed. In addition, raising awareness concerning emotional eating risks during challenging life transitions and distressing situations is necessary. The college leadership, led by the departments of Nutrition, Psychology, and Public Health, in collaboration with stakeholders in the Israeli Ministry of Health, must consider the mental effects of war on students and their involvement in emotional eating.

Higher morning cortisol is associated with lower intuitive eating in midlife women

BACKGROUND

Stress is associated with negative health outcomes in adults, including increased adiposity. Eating behaviors to cope with stress can have a negative effect on adiposity. There is limited research on positive eating behaviors, such as intuitive eating (IE), and their relationship to stress and adiposity. Thus, this study aimed to examine the association between stress and adiposity and to assess whether IE is a mediator of that pathway.

METHODS

Data were analyzed from a cross-sectional study of 114 women between 40-64 years of age. Participants completed in-person visits and self-reported questionnaires, including the Intuitive Eating Scale and Perceived Stress Scale. Adiposity was assessed using dual energy x-ray absorptiometry. Measurements included total body fat percentage and android/gynoid (AG) ratio as a measure of abdominal adiposity. Participants provided ten salivary cortisol samples over two days, collected upon waking, 30-, 45-, and 60-minutes after waking, and prior to bed. Several methods were used to characterize cortisol secretion and exposure, including the diurnal cortisol slope and the cortisol area under the curve with respect to ground (AUCg). Linear regression was used to assess the associations between perceived stress and IE and between features of diurnal cortisol and IE. Mediation models were tested to examine the indirect effects of IE on the relationship between perceived stress and adiposity and to test the indirect effects of IE on the relationship between cortisol measures and adiposity.

RESULTS

Linear regression analyses indicated that higher cortisol AUCg was associated with lower scores on the eating for physical reasons subscale (β: -0.01, p = 0.008). After adjusting for covariates, neither higher perceived stress nor diurnal cortisol were associated with intuitive eating. There was no evidence of mediation of the association of stress on adiposity through IE.

CONCLUSION

Our findings demonstrate a relationship between higher overall morning cortisol and lower scores on the eating for physical reasons subscale of the Intuitive Eating Scale. Future research should seek to understand how intuitive eating may be used as a technique for individuals who engage in emotional eating to cope with stress, and to prevent excess adiposity resulting from stress in midlife women.

Intuitive eating and its influence on self-reported weight and eating behaviors

Intuitive eating (IE) is an adaptive eating behavior that involves paying attention to the body's physiological signals, including eating when hungry and stopping when feeling full. A growing body of literature has examined the effect of IE on the development of maladaptive eating behaviors and body weight, even though IE is not centered around the latter. However, longitudinal observation studies among the general population are still rare. Therefore, this study aimed to longitudinally examine the links between IE and changes in body weight, maladaptive eating behaviors (reward, external, restrained eating), and overeating frequency over time. For this purpose, we used data from the first (2017) and the fourth waves (2020) of the Swiss Food Panel 2.0 survey, which included 1821 randomly selected Swiss participants. The same participants completed a self-administered questionnaire annually, measuring their self-reported eating behaviors and weight status. IE was measured with the Intuitive Eating Scale-2. Results showed that women with high IE scores were more likely to maintain their body weights (within ±2 kg) and less likely to gain weight (>2 kg) than women with low IE scores. No such effects were found for men. Furthermore, IE was linked to a reduction in maladaptive eating behaviors and overeating frequency over time in both genders. Results suggest that IE may counteract maladaptive eating behaviors, which can promote weight stability over time. Therefore, the encouragement of IE patterns seems to be a promising strategy to address problematic eating behaviors and the challenges associated with controlling food intake and prevention of overeating.

Family cohesion and intuitive eating in Chinese college students: A serial mediation model

Improving intuitive eating can effectively prevent emotional eating, restrained eating, and overeating, and help improve people's physical and mental health. Based on the acceptance model of intuitive eating, ecological systems theory, family stress model, and transactional model of stress and coping, the present study aimed to explore the relationship between family cohesion and intuitive eating and its underlying mechanisms through a cross-sectional study design. A random sample of 702 college students from 29 provinces in China, aged from 18 to 26 years (54.56% male, M age = 21.12 years), voluntarily participated in the survey. Demographic variables, family cohesion, intuitive eating, perceived stress, and coping style were measured. The results indicated that family cohesion was significantly positively correlated with intuitive eating and the direct effect between them was significant. Meanwhile, there was a significant indirect effect of family cohesion on intuitive eating through perceived stress and positive coping styles. Moreover, perceived stress and positive coping styles, rather than negative coping styles, acted as serial mediators in the association between family cohesion and intuitive eating. The findings shed light on the prevention and intervention for disordered eating and obesity and provided a new theoretical perspective for the mental health education of college students. In addition, implications and directions for future research were also discussed.

Sex and ethnic/racial differences in disordered eating behaviors and intuitive eating among college student

Introduction

Eating behaviors encompass disordered eating behaviors (e.g., overeating, binge eating, and associated symptoms of binge eating) and intuitive eating. Certain disordered eating behaviors, including binge eating, are more prevalent among female and ethnic/racial-minority college students than male and/or non-Hispanic White college students. However, sex and ethnic/racial differences among college students with other disordered eating (e.g., associated symptoms of binge eating) and intuitive eating behaviors remain unclear.

Methods

In 2022, 887 college students (Mage = 20.9 ± 2.6 years) self-reported their sex, ethnicity/race, disordered eating behaviors (e.g., overeating, binge eating, associated symptoms of binge eating), and intuitive eating. To examine sex and ethnic/racial differences among these students, we used modified Poisson regressions for students who reported disordered eating and linear regressions for students who reported intuitive eating.

Results

Except for overeating, disordered eating behaviors were more prevalent among female [adjusted prevalence ratio (aPR) = 1.3-1.8] than male college students after adjusting for sociodemographic variables, whereas intuitive eating scores did not differ by sex. Across ethnic/racial groups, disordered eating was more prevalent among all ethnic/racial-minority college students (aPR = 1.2-2.3) than non-Hispanic White college students after adjusting for sociodemographic variables. Moreover, non-Hispanic Black or African American college students had higher intuitive eating scores than non-Hispanic White college students (adjusted β = 0.7, 95% CI = -0.2, 1.6).

Conclusion

In our sample, notable differences emerged in the prevalence of disordered eating behaviors and mean scores by sex and ethnicity/race, while differences in intuitive eating scores emerged based on ethnicity/race.

Higher intuitive eating is associated with lower adiposity in midlife women

OBJECTIVE

Intuitive eating (IE) is consistently associated with a lower body mass index, though its relationship with adiposity, specifically abdominal adiposity, is unknown. Given that midlife women often experience increases in adiposity during midlife, our objective was to examine the association between IE and adiposity in midlife women. We also aimed to validate the factor structure of the Intuitive Eating Scale (IES) in a sample of midlife women.

METHOD

We analyzed data from a cross-sectional study of 116 women between 40 and 64 years of age. Participants completed in-person visits and self-reported questionnaires, including the 21-item IES. Adiposity was assessed using dual energy x-ray absorptiometry. Measurements included total body fat percentage and android/gynoid (AG) ratio as a measure of abdominal adiposity.

RESULTS

Confirmatory factor analysis of the IES demonstrated a poor fit to the data. Thus, we conducted an exploratory factor analysis which resulted in a 15-item scale with five items on each subscale, and demonstrated improved fit. Higher intuitive eating was associated with lower total body fat percentage (β = -6.77, p < 0.0001) and lower abdominal adiposity (β = -0.09, p = 0.0005). Higher scores on eating for physical reasons and reliance on internal hunger and satiety cues were associated with lower total body fat and lower abdominal adiposity.

CONCLUSIONS

Our findings suggest that higher intuitive eating is associated with lower total body fat percentage and lower abdominal adiposity. These results may have public health implications to promote intuitive eating in midlife women, a population at risk of weight gain and changes to body fat distribution.

Sex differences in intuitive eating and its relationship with body mass index among adults aged 18-40 years in Saudi Arabia: a cross-sectional study

Introduction

Intuitive eating (IE) is eating without judgment, relying only on physiological hunger and satiety. Sex differences in IE have been reported; however, none of the studies have explicitly examined IE and its relationship with body mass index (BMI) in the Saudi Arabian population. Thus, this study aimed to investigate sex differences in IE and its relationship with BMI in the Saudi population.

Subjects/methods

A cross-sectional online survey of 360 participants (18 years or older) with self-reported weight and height was conducted. IE was measured using the Intuitive Eating Scale-2 (IES-2). Separate multiple linear regression analyses were conducted to determine if total IE and its subscale scores differed across sexes. It was also conducted to assess the relationship between IE and BMI across sexes.

Results

Women had higher total IE score, eating for physical rather than emotional reasons (EPR), and body-food choice congruence (BFCC) scores compared to men (p = 0.013, p = 0.01, p <0.001, respectively). The analysis showed a significant negative association between total IE, BFCC, EPR scores, and BMI in women compared to men (p = 0.023, p = 0.01, p = 0.003, respectively).

Conclusion

The data on the sex differences in IE and its subscales and their different association with BMI encourage tailing nutrition-related recommendations in the context of intuitive eating based on sexes. Future studies are needed to explore how intuitive eating functions differently in women compared to men and explore the causal relationship between IE and BMI in this population.

Emotional Eating in College Students: Associations with Coping and Healthy Eating Motivators and Barriers

BACKGROUND

Emotional eating, or eating in response to stress and other negative affective states, bears negative consequences including excessive weight gain and heightened risk of binge eating disorder. Responding to stress with emotional eating is not universal, and it is important to elucidate under what circumstances and by what mechanisms stress is associated with emotional eating. This is particularly important to understand among college students, who are at risk of experiencing heightened stress and negative changes to dietary habits.

METHOD

The present study investigated the relationships among perceived stress, emotional eating, coping, and barriers to and motivators of healthy eating both concurrently and 1 year later in a sample of young adult college students (n = 232).

RESULTS

At baseline, emotional eating was significantly associated with perceived stress (r = 0.36, p < .001), barriers to (r = 0.31, p < .001) and motivators of (r =  - 0.14, p < .05) healthy eating, and avoidance coping (r = 0.37, p < .001), but not approach coping. Furthermore, avoidance coping mediated (indirect effect b = 0.36, 95% CI = 0.13, 0.61) and moderated (b =  - 0.07, p = 0.04) the relationship between perceived stress and emotional eating. Contrary to study hypotheses, baseline stress levels were not associated with emotional eating 1 year later.

CONCLUSION

College students who utilize avoidance coping strategies may be particularly susceptible to the effects of stress on emotional eating. Healthy eating interventions targeting college students might address stress coping strategies in addition to reduction of barriers to healthy eating.

Obesity, Chronic Stress, and Stress Reduction

The obesity epidemic is caused by the misalignment between human biology and the modern food environment, which has led to unhealthy eating patterns and behaviors and an increase in metabolic diseases. This has been caused by the shift from a "leptogenic" to an "obesogenic" food environment, characterized by the availability of unhealthy food and the ability to eat at any time of day due to advances in technology. Binge Eating Disorder (BED) is the most commonly diagnosed eating disorder, characterized by recurrent episodes of binge eating and a sense of loss of control over eating, and is treated with cognitive-behavioral therapy-enhanced (CBT-E). Shift work, especially night shift work, can disrupt the body's natural circadian rhythms and increase the risk of obesity and other negative health consequences, such as cardiovascular disease and metabolic syndrome. One dietary approach to address circadian dysregulation is time-restricted eating (TRE), which involves restricting food intake to specific periods of the day to synchronize the body's internal clock with the external environment. TRE has been found to cause modest weight loss and improve metabolic outcomes such as insulin sensitivity and blood pressure, but the extent to which it is beneficial may depend on adherence and other factors such as caloric restriction.

A qualitative exploration of perceived barriers and facilitators to following an intuitive eating style

BACKGROUND

Intuitive eating involves following internal cues of hunger and satiety to guide eating choices as opposed to responding to external signals, strong emotions, or dietary rules. This style of eating has consistently been shown to be related to better physical and psychological health indicators, and more interventions are being designed and studied to promote this eating style. The current study aimed to identify anticipated facilitators and barriers to following this style of eating among a group of college students enrolled in a larger study of intuitive eating.

METHOD

Following a week of tracking their current eating as part of a larger study, college students read a description of intuitive eating. They then answered three open-ended questions about following intuitive eating including facilitators, barriers, and perceived ability to follow long term. Responses were coded using thematic analysis to identify themes across responses.

RESULTS

Among 100 participants, 86 % were female, 46 % were Hispanic (41 % non-Hispanic White, 13 % other race/ethnicity), mean age was 24.3 years, and mean body mass index was 26.2. The most commonly anticipated participant-reported facilitators of intuitive eating were being in touch with the body's needs and hunger cues, positive perceptions of intuitive eating, and health considerations. The most commonly anticipated barriers were logistical constraints (e.g., busyness and mealtimes), difficulty with hunger cues and reactions to food, and negative perceptions of intuitive eating. The majority of participants (64 %) would consider following this style of eating long term.

DISCUSSION

This study provides information that can be used to improve efforts aimed at promoting intuitive eating to college students, including marketing intuitive eating interventions, and clarifying misunderstandings of its key tenets that might serve as barriers.

Associations between mind-body practice engagement and diet quality: Exploring the mediating roles of eating behaviour traits and regulation styles for eating behaviours in the PREDISE study

While engaging in Mind-Body Practices (MBPs) may be related to better diet quality, its association with eating behaviours is unclear. This cross-sectional study explores whether eating behaviour traits and regulation style of eating behaviours mediate the association between MBP engagement and diet quality. A total of 418 women and 482 men, aged between 18 and 65 years and recruited as part of the PREDISE study cohort, reported whether they currently practice one or more MBP (e.g., yoga or meditation). Canadian Healthy Eating Index (C-HEI) was calculated from three 24h dietary recalls. Intuitive Eating Scale (IES-2), and Regulation of Eating Behaviour Scale were completed online. Mann-Whitney tests were conducted to compare C-HEI scores of individuals who currently engage in MBPs (practitioners) to those who do not (non-practitioners). Multiple regression analyses and bootstrapping were performed to test whether eating behaviours and regulation style of eating behaviours mediate the association between MBPs and diet quality. Overall, 88 women and 43 men were practitioners. They had higher C-HEI scores than non-practitioners (62.9 ± 13.0 vs. 55.6 ± 14.3; p = 0.001). Parallel mediation model showed significant indirect effects of the IES-2 subscale relating to Body-Food Choice Congruence (β = 1.57, SE = 0.41, 95% CI: 0.86, 2.43), self-determined motivation (β = 1.51, SE = 0.39, 95% CI:0.81, 2.32) and non-self-determined motivation (β = 0.39, SE = 0.21, 95% CI: 0.03, 0.85) on the association between practitioner status and C-HEI. These findings suggest that the current practice of MBPs is associated with better diet quality, mainly through practitioners' higher intuitive eating skills and more self-determined regulation of eating behaviours. Further studies should investigate the potential impacts of MBPs on the development and maintenance of positive eating habits.

Body image explains differences in intuitive eating between men and women: Examining indirect effects across negative and positive body image

Intuitive eating is an adaptive and flexible form of eating. Men report higher rates of intuitive eating than women. Objectification processes are proposed to underlie this (binary) gender difference due to the intense body-related pressures that disrupt body image in women. The current study is the first known to test whether body image indirectly explains lower levels of intuitive eating in women relative to men. A cross-sectional sample of 498 adults aged 18-74 years recruited through Prolific completed an online survey assessing intuitive eating and negative and positive body image indicators. Women reported poorer body image and lower levels of intuitive eating compared to men. Significant indirect effects suggested body image explained gender differences in intuitive eating, controlling for age and body mass index. In women relative to men, greater body surveillance and lower aesthetic satisfaction explained lower total intuitive eating and reliance on hunger and satiety, greater aesthetic investment explained lower total intuitive eating and eating for physical reasons, and lower functionality investment explained lower body-food choice congruence. More research is needed, but findings suggest programs may benefit from decreasing critical views of appearance and strengthening functionality investment in women to reduce gender differences in intuitive eating.

Group differences in binge eating, impulsivity, and intuitive and mindful eating among intermittent fasters and non-fasters

Intermittent fasting (IF) is an increasingly popular diet involving short-term fasting and/or caloric restriction. While published research highlights physiological effects (e.g., weight, body fat) of IF, hardly any research has examined its associations with psychological factors. This study aimed to investigate the relationship between IF and binge eating, impulsivity, intuitive eating, and mindful eating. An undergraduate sample (N = 298) was recruited through a large southwestern university psychology subject pool. The sample was divided into three groups based on IF status: Current IF (n = 70), Past IF (n = 48), and No IF (n = 182). Current IF was negatively associated with lack of perseverance (e.g., "I generally like to see things through to the end"; p < .01) and intuitive eating (p < .05), varying by subscale, compared to the other groups. Notably, Past-IF, but not Current IF, participants were more likely to binge eat than individuals who reported never fasting (p = .03). These findings add credence to the rapidly developing area of research suggesting IF is associated with increased disordered eating behaviors. Notably, the findings from this study are limited due to the lack of diversity sample, such that generalizations can only be made toward White, middle-to-high income, college students. Future longitudinal studies are needed to test the directionality of these relationships.

A structural invariance analysis of the acceptance model of intuitive eating across black, hispanic, and white young-adult women

In this cross-sectional study, structural invariance of the acceptance model of intuitive eating was examined between a sample of Black (n = 420), Hispanic (n = 420), and White (n = 435) cisgender women between the ages of 18-30 years old residing in the United States. Mean age for the total sample (n = 1275) was 24.17 years old (SD = 3.65). Women were recruited via Qualtrics Sampling, and self-report measures were administered online. Multigroup analyses were employed within a structural equation modeling framework, and measurement invariance at the configural, metric, scalar, and strict/residual levels was investigated first. After uncovering and accounting for several error variances that were non-invariant, multigroup structural invariance analyses indicated that paths within the model were invariant across the three ethnicities of women. BMI was also incorporated into the model, which, likewise, showed invariance in its associations with specific constructs. With due cautions related to the impact of cultural ideals regarding appearance and the interplay of ethnicity and body-related experiences among women, these results provide preliminary evidence that the model may apply to Black, White, and Hispanic women in the U.S.

Disconnect between sympathetically-induced hunger suppression and consumption among highly restrained eaters following stress

Despite emphasis on findings suggesting restrained eaters increase food consumption under stress, unrestrained eaters' reduction in intake is more robust. Early proposals asserted unrestrained eaters significantly reduced intake after certain threats due to the hunger-inhibiting effects of autonomic influences, presuming unrestrained eaters are more responsive to these effects and restrained eaters rely less on physiological cues for eating. However, scant empirical evidence has substantiated these claims. This study examined whether a sequence exists whereby stress elicits autonomic activation, autonomic activation impacts hunger, and hunger then impacts eating, with dietary restraint altering the hunger-intake link. It was hypothesized that sympathetic nervous system activation would be greatest when ongoing safety from stress was uncertain, sympathetic activation would be linked to reduced hunger, and lower hunger would be associated with attenuated intake. Restraint, conceptualized via Hagan et al.'s (2017) latent restraint factors, was hypothesized to reduce the association between hunger and intake. Female participants (n = 147) were randomized to a stress + certain safety, stress + uncertain safety, or control condition. Sympathetic nervous system activity was recorded prior to a bogus taste test, which quantified ad libitum consumption of highly-palatable snack foods post-stress. Only the stress + uncertain safety condition exhibited greater sympathetic nervous system activity than the control condition. A significant index of moderated serial mediation emerged for Preoccupation with Dieting and Weight-Focused Restraint in the stress + uncertain safety condition. Though sympathetic activation decreased hunger similarly regardless of dietary restraint, only less restrained individuals significantly decreased intake. More restrained individuals ate more despite experiencing lower hunger. The disconnect between hunger and intake in more restrained eaters suggests that focus on enhancing attunement to hunger may yield greater benefit than enhancing restraint. 281 words.

A survey of eating styles in eight countries: Examining restrained, emotional, intuitive eating and their correlates

INTRODUCTION

Restrained, emotional and intuitive eating were examined in relation to each other and as correlates of participants' weight status, body image and self-esteem. In some past research, restrained and emotional eating have been associated with higher weight status and poorer mental health, while intuitive eating is more frequently linked to lower weight status and more positive well-being. However, these eating styles have rarely been examined together and never in a large cross-country sample.

METHOD

Six-thousand two-hundred and seventy-two (6272) emerging adults (M age = 21.54 years, SD = 3.13) completed scales from the Three-Factor Eating Questionnaire, the Eating Disorders Examination Questionnaire, the Intuitive Eating Scale-2, the Multidimensional Body Self Relations Questionnaire, the Rosenberg Self-Esteem Scale, and provided weight and height information that was used to calculate body mass index (BMI). Participants resided in Australia, Belgium, Canada, China, Italy, Japan, Spain and the United States and provided information using an online survey.

RESULTS

Path analyses for the entire sample revealed significant pathways between higher intuitive eating and higher body satisfaction and self-esteem, and lower BMIs among participants. Higher levels of restrained and emotional eating were associated with lower body satisfaction and self-esteem, and higher BMIs among participants. Minor cross-country differences were evident in these patterns of relations, but intuitive eating emerged as a consistent predictor across countries.

CONCLUSION

Overall, findings suggest that efforts should be made to increase intuitive eating among emerging adults and to support individual and macrolevel interventions to decrease restrained and emotional eating behaviours.

Emotional and intuitive eating: an emerging approach to eating behaviours related to obesity

Emotional and intuitive eating are associated with obesity. In the present study, it was aimed to evaluate the relationship between intuitive eating and emotional eating behaviours in adults with anthropometric measurements of obesity-related disease risk and gender. Body weight, body mass index (BMI), waist, hip and neck circumferences were taken. Emotional Eater Questionnaire and Intuitive Eating Scale-2 were used for the assessment of eating behaviour. A total of 3742 adult individuals (56⋅8 % (n 2125) female and (n 1617) male) were participated voluntarily. The total score and subscales of EEQ were higher in females than males (P < 0⋅001). The scores of the IES-2 subscales and the total score were higher in males than females (P < 0⋅05). In metabolic risk classification according to waist and neck circumference, EEQ scale scores (except type of food) were higher in the metabolic risk group, while IES-2 (except body-food congruence in neck circumference) scores were higher in the non-risk group (P < 0⋅05). While there was a positive correlation between EEQ and body weight, BMI, waist circumference, waist-height ratio, a negative correlation was found between age and waist-hip ratio. There was a negative correlation between IES-2 and body weight, BMI, waist-height ratio, waist-hip ratio. In addition, a negative correlation was found between IES-2 and EEQ. Intuitive eating and emotional eating differ by gender. Anthropometric measures and metabolic disease risk is associated with emotional eating and intuitive eating. Interventions to increase intuitive and decreasing emotional eating behaviour can be effective in preventing both obesity and obesity-related diseases.

Morning individuals in Saudi Arabia have higher self-regulation of eating behavior compared to evening types

Chronotype is a manifestation of an individual's circadian system, which can be presented as a preference for morningness or eveningness. Evening chronotype has been linked to unhealthy dietary habits. These habits are partially from poor self-regulation of eating behavior (SREB). SREB is a goal-directed process that helps resist food temptation and achieve desired dietary outcomes. It is unclear whether chronotype is associated with SREB. This study aims to investigate the association between chronotypes and SREB. A total of 599 adults (18-50 years) enrolled in this cross-sectional study. Participants received an online questionnaire that collected sociodemographic, anthropometrics, chronotype through the validated reduced Morningness-Eveningness Questionnaire (rMEQ) and SREB using the SREB Questionnaire. ANOVA, Chi-square and multivariate logistic regression were used. In adjusted models, morning types had 85% higher SREB compared to evening types (p = 0.003, OR = 1.85). Evening types found fried foods (p = 0.003), chips (p = 0.005) and French fries (p = 0.018) more tempting than morning types. These findings show a link between chronotype and SREB. Strategies focusing on SREB may help evening types improve dietary habits. Further studies are required to clarify the underlying mechanisms for these associations. This may have important implications for lifestyle and behavioral change policy.

A Tailored Gender-Sensitive mHealth Weight Loss Intervention (I-GENDO): Development and Process Evaluation

BACKGROUND

Given the increase in the prevalence of overweight and obesity worldwide, the number of digital weight loss interventions has also risen. However, these interventions often lack theoretical background and data on long-term effectiveness. The consideration of individual and gender differences in weight-related psychological parameters might enhance the efficacy and sustainability of mobile-based weight loss interventions.

OBJECTIVE

This paper presented an introduction to and the process evaluation of a 12-week gender-sensitive mobile health (mHealth) weight loss intervention (I-GENDO) combining computer-based and self-tailoring features.

METHODS

Between August 2020 and August 2021, individuals with overweight (BMI 25.0-29.9 kg/m²), those with obesity class I (BMI 30.0-34.9 kg/m²), and those with obesity class II (BMI 35.0-39.9 kg/m²) were recruited to the I-GENDO project, a multicenter study in Germany. The mHealth intervention aimed at targeting individual psychological factors associated with the development and persistence of overweight and obesity (eg, emotional eating) using computer-based tailoring. Moreover, the intervention took a gender-sensitive approach by implementing self-tailoring of gender-targeted module versions. The computer-based assignment of the main modules, self-selection of gender-targeted module versions, and use patterns were evaluated while considering gender. Moreover, gender differences in the usability assessment were analyzed.

RESULTS

Data from the intervention arm of the study were processed. A total of 116 individuals with overweight and obesity (77/116, 66.4% women; age mean 47.28, SD 11.66 years; BMI mean 33.58, SD 3.79 kg/m2) were included in the analyses. Overall, the compliance (90/109, 82.6%) and satisfaction with the app (mean 86% approval) were high and comparable with those of other mobile weight loss interventions. The usability of the intervention was rated with 71% (5.0/7.0 points) satisfaction. More women obtained the main module that focused on emotion regulation skills. Most men and women selected women-targeted versions of the main modules. Women used the app more frequently and longer than men. However, women and men did not differ in the progress of use patterns throughout the intervention.

CONCLUSIONS

We developed a tailored gender-sensitive mHealth weight loss intervention. The usability of and engagement with the intervention were satisfactory, and the overall satisfaction with the intervention was also high. Gender differences must be considered in the evaluation of the effectiveness and sustainability of the intervention.

Lifestyle health behavior correlates of intuitive eating in a population-based sample of men and women

The aim of this observational study was to examine how lifestyle health behaviors hypothesized to influence attunement to internal cues (breakfast consumption frequency, physical activity, yoga practice, sleep, and recreational screen time) are cross-sectionally related to intuitive eating (IE). Data from 765 men and 1009 women (M_age = 31.1 ± 1.7 years) who participated in Project EAT-IV (Eating and Activity in Teens and Young Adults) were analyzed with sex-stratified linear regression models adjusted for age, race/ethnicity, socioeconomic background, and parent status. Sociodemographic-adjusted mean levels of each health behavior by sex were generated at low (one standard deviation below the mean), average (at the mean), and high (one standard deviation above the mean) levels of IE to facilitate interpretation of regression results. Among women only, more frequent breakfast consumption (p = .02), more time spent practicing yoga (p = .03), more sleep (p = .004), and less recreational screen time (p = .01) were each significantly associated with higher IE after adjusting for sociodemographic characteristics. Compared to women with low IE, women with high IE reported, on average, eating breakfast 0.3 more days a week, practicing 12 more minutes of yoga per week, getting 12 more minutes of sleep per night, and engaging in 18 fewer minutes of recreational screen time per day. Results suggest that these modifiable health behaviors may be valuable targets for interventions to increase IE among women, though longitudinal research is needed to elucidate the temporality of these associations.

Social jet lag and eating styles in young adults

Social jet lag refers to circadian misalignment that occurs when people shift their sleep schedules from weekdays to weekends. Social jet lag is linked with numerous negative health outcomes, with emerging research connecting social jet lag to increased consumption of unhealthy foods. Existing research has not yet examined the associations between social jet lag and eating styles (e.g., emotional eating). Emotional eating and loss of control over eating are problematic eating styles which may lead to overeating and weight gain. Conversely, intuitive eating is associated with positive health outcomes such as lower risk of obesity. The present study examined social jet lag and eating styles in a young adult sample, as emerging adulthood is an important developmental time period for establishing healthy sleep and eating habits. Results of the current study indicated that in a sample of 372 American undergraduate participants, social jet lag significantly predicted lower intuitive eating (β = -.129, p = .012) and greater emotional eating (β = .12, p = .022) when controlling for age, sex, and chronotype. It was marginally predictive of loss of control over eating (β = .102, p = .050). Sleep quantity on weekdays (not weekends) also significantly predicted intuitive eating (p = .017) and loss of control over eating (p = .044), and sleep quality significantly predicted intuitive eating (p < .001), emotional eating (p < .001), and loss of control over eating (p < .001). These findings extend our understanding of the relationship between social jet lag and eating styles in college students. Addressing social jet lag in this population is an important consideration for their cardiometabolic health and for reducing weight fluctuations.

Eating behaviors, eating styles and body mass index during COVID-19 confinement in a college sample: a predictive model

BACKGROUND

COVID-19 confinement affected lifestyles. There is inconclusive evidence about changes in eating patterns, and there are few studies on the impact on body mass index (BMI), the occurrence of dysfunctional behaviors (binge eating, fat intake), and the predictive role of maladaptive eating styles (emotional, external, and restrained eating).

OBJECTIVES

(1) To analyze the differences in binge eating, fat intake, BMI, and maladaptive eating styles before and during COVID-19 confinement, and (2) to analyze whether maladaptive eating styles (before confinement) predicted binge eating, fat intake, and BMI during confinement.

METHODS

The sample consisted of 146 Spanish college students, divided into 104 females (71.2%; age: M = 22.20, SD = 2.97) and 42 males (28.8%; age: M = 24.74; SD = 3.53). All completed several dietary measures and BMI twice: before COVID-19 confinement (T1, November 2019) and during COVID-19 confinement (T2, April 2020).

RESULTS

BMI and maladaptive eating styles did not change in T2 (vs. T1). However, binge eating and fat intake decreased in T2. Emotional eating at T1 positively predicted BMI and binge eating at T2. External eating at T1 positively (and marginally) predicted fat intake at T2. Restrained eating at T1 positively predicted binge eating at T2, and negatively (and marginally) predicted BMI and fat intake at T2. The model explained 80.5% of the variance in BMI, 41.5% of the variance in binge eating, and 25.8% of the variance in fat intake during COVID-19 confinement.

CONCLUSIONS

The COVID-19 confinement had a positive impact on some eating behaviors. Future policies should focus part of their prevention on maladaptive eating styles to curb dysfunctional eating behaviors and BMI problems in times of stress.

Dissonance-based eating disorder prevention improves intuitive eating: a randomized controlled trial for Brazilian women with body dissatisfaction

PURPOSE

Investigate the efficacy of a dissonance-based (DB) intervention (i.e., the Body Project), during which some examples of intuitive eating were provided by peer leaders, in improving intuitive eating and targeting risk and protective factors for eating disorders (ED) among Brazilian women with body dissatisfaction.

METHODS

Participants were randomized to a four-session DB intervention (n = 38) or assessment-only control (AOC) (n = 36), and completed validated measures assessing intuitive eating, body appreciation, self-esteem, body-ideal internalization, body dissatisfaction, negative affect, and disordered eating pre-intervention, post-intervention, and at 4- and 24-week follow-ups.

RESULTS

The DB condition demonstrated significantly greater increases in intuitive eating, body appreciation and self-esteem scores compared to AOC from pre-intervention to post-intervention (between-condition Cohen's d = 0.73-0.98), 4-week (between-condition Cohen's d = 1.25-1.87) and 24-week follow-up (between-condition Cohen's d = 0.82-1.38). Also, the DB condition showed significantly greater decreases in body-ideal internalization, body dissatisfaction and disordered eating scores from pre-intervention to post-intervention (between-condition Cohen's d = 0.76-1.04), 4-week (between-condition Cohen's d = 1.27-1.71) and 24-week follow-up (between-condition Cohen's d = 1.04-1.19). Regarding negative affect, DB condition showed significantly greater reduction only at 24-week follow-up (between-condition Cohen's d = 0.60).

CONCLUSION

Results reinforce the efficacy of DB interventions in reducing ED risk factors for young women and support the preliminary efficacy of these programs in improving intuitive eating, body appreciation, and self-esteem.

The Complicated Relationship between Dieting, Dietary Restraint, Caloric Restriction, and Eating Disorders: Is a Shift in Public Health Messaging Warranted?

The origins of theories specifying dietary restraint as a cause of eating disorders can be traced to the 1970s. This paper will present an overview of the origins of dietary restraint theories and a brief historical review of evidence will be summarized. Recent research will be presented, including the results from the CALERIE Phase 1 study, as well as CALERIE Phase 2, which were NIH-sponsored randomized controlled trials. CALERIE 2 provided a test of the effect of two years of caloric restriction (CR) on the development of eating disorder syndromes and symptoms in comparison to a control group that did not alter eating behavior or body weight. The intervention was effective for inducing a chronic (two-year) reduction in total energy expenditure and increased dietary restraint but did not increase symptoms of eating disorders. The results of this recent investigation and other studies have not provided experimental support for conventional dietary restraint theories of eating disorders. These findings are discussed in terms of potential revisions of dietary restraint theory, as well as the implications for a paradigm shift in public health messaging related to dieting.

Modeling the associations between internal body orientation, body appreciation, and intuitive eating among early-adult and middle-adult men and women: A multigroup structural invariance analysis

This cross-sectional study investigated the associations among internal body orientation, body appreciation, intuitive eating, age, and BMI in men and women between 30 and 70 years old as delineated in the acceptance model of intuitive eating. Self-report measures were administered to a final sample of 522 individuals consisting of early-adult men (ages 30-44; n = 153), middle-adult men (ages 45-70; n = 108), early-adult women (ages 30-44; n = 135), and middle-adult women (ages 45-70; n = 126). Overall mean age was 45.03 (SD = 10.95). Structural equation modeling evidenced that, for both age groups of men and women, internal body orientation was positively associated with body appreciation and body appreciation was positively associated with intuitive eating. Internal body orientation was positively associated with intuitive eating in each group, except early-adult women. The associations among age and BMI with the aforementioned variables were inconsistent. Although evidencing measurement non-invariance among a number of parameters, multigroup structural invariance analyses showed that the associations among internal body orientation, body appreciation, intuitive eating, age, and BMI were invariant across each gender and age. These results further confirm components of the acceptance model of intuitive eating among men and women in early-adulthood and middle-adulthood.

Feel Good, Eat Better: The Role of Self-Compassion and Body Esteem in Mothers' Healthy Eating Behaviours

Mothers’ eating behaviours are important to ensure the health and well-being of themselves and their families. Recent research has pointed to self-compassion, defined as extending kindness to oneself in times of perceived inadequacy or general suffering, as a trait associated with healthy forms of eating, such as intuitive eating, and reduced maladaptive forms of eating, such as emotional eating. However, little is known about the psychological mechanism through which self-compassion relates to healthy eating behaviours. This study examined 100 mothers’ levels of self-compassion, body esteem and eating behaviours. Structural equation modelling revealed that self-compassion was positively associated with diet quality and intuitive eating, while being negatively associated with emotional eating. Moreover, these links occurred, in part, due to higher body esteem. This points to a mechanism through which self-compassion may positively contribute to mothers’ healthy eating behaviours. The implications for eating outcomes and women’s health are discussed.

Intuitive eating and its psychological correlates: A meta-analysis

OBJECTIVE

Intuitive eating is an adaptive style of eating that has generated significant research attention. Theoretically, intuitive eating is a core construct that features prominently in the Acceptance Model of Intuitive Eating, a framework that explains how positive environmental influences can foster intuitive eating practices via body appreciation. Empirically, intuitive eating has been connected to a broad range of adaptive mental health indices. At present, a quantitative synthesis of intuitive eating and its correlates has yet to be conducted. This was the objective of the current meta-analysis.

METHOD

Ninety-seven studies (89% cross-sectional) were included. Random effects meta-analyses were conducted on 23 psychological correlates, divided into three clusters: eating behavior and body image disturbances, positive body image and other adaptive factors, and general psychopathology. Meta-analytic path analyses were also computed to test the validity of the Acceptance Model.

RESULTS

Intuitive eating was inversely associated with multiple indices of eating pathology, body image disturbances, and psychopathology (rs = -.23 to -.58). Intuitive eating was positively associated with numerous positive psychological constructs, such as positive body image, self-esteem, and wellbeing (rs = .20 to .58). Men reported higher levels of intuitive eating than women (d = 0.39), with differences being largest in Caucasian samples. Meta-analytic path analyses strongly supported the hypothesized pathways specified in the Acceptance Model of Intuitive Eating.

CONCLUSIONS

There is a strong evidence base for intuitive eating's connection to numerous adaptive psychological constructs. Attention should now shift toward prospective and experimental designs so that the temporal nature of these relationships can be identified.

Health-Risk Behaviors and Dietary Patterns Among Jordanian College Students: A Pilot Study

Background/Aims: Health promotion and the incorporation of health-protective behaviors in people's lifestyles have a great role in enhancing individuals' overall health and well-being. College students are at increased risk of developing unhealthy dietary and lifestyle behaviors. A cross-sectional pilot study was conducted to assess the health-risk behaviors among undergraduate college students at Jordan University of Science and Technology. Methods: The final sample included 136 students, with a mean age of 21.1 ± 2.37 years, mostly females (69%). A self-reported questionnaire was used for data collection about dietary and lifestyle behaviors among college students. The questionnaire consisted of four parts: sociodemographic characteristics, body weight classifications, lifestyle behaviors, and dietary patterns and intake, and eating behaviors. Results: Most of the students did not meet the daily recommendations for fruit (76%) and vegetable (82%) intake. Males were significantly consuming fast food more frequently (p = 0.019), and smoked cigarettes (p < 0.001) or hookah (p = 0.015) more frequently than did females. Further, the majority met the recommendations for physical activity (81%), but exceeded recommendations for sedentary behavior. Females were more likely to have normal weight or be underweight (OR = 4.865), to have a fear of weight gain (OR = 3.387), and to have the recommended sleeping hours (OR = 7.685) than were males. Conclusion: The results indicate the health-risk behaviors and the gender-related differences among college students.

Prevalence of negative emotional eating and its associated psychosocial factors among urban Chinese undergraduates in Hong Kong: a cross-sectional study

Background

Emotional eating (EE), defined as eating in response to a range of emotions, has been previously associated with poor diet and obesity. Since there are limited data from non-Western populations, this study aims to examine the prevalence and factors associated with EE among urban Chinese university students.

Methods

A cross-sectional study was conducted on 424 university students (aged 18–24 years) from two large universities in Hong Kong in 2019. Respondents completed an anonymous online questionnaire that contained background questions, an emotional eating subscale of the Dutch Eating Behaviour Questionnaire (DEBQ), and Depression Anxiety and Stress Scales (DASS-21). Two-sample independent t-test and multiple regression analyses were conducted to test the association of study variables with negative emotional eating.

Results

There was over a three-fold higher likelihood of negative EE among females (14.8%) when compared with their male counterparts (4.5%) (OR = 3.7, p < 0.05). Having at least mild depressive symptoms was the only independent factor associated with negative EE among males (OR = 10.1) while for females, negative EE was independently associated with not having a romantic partner (OR = 3.45), having depressive symptoms (OR = 44.5), and having at least mild stress (OR = 5.65). Anxiety levels were not independently associated with negative EE for either gender. Both male and female students with negative EE had significantly lower self-perceived health scores, higher body mass index, and lower life satisfaction scores.

Conclusions

This study revealed that negative EE is prevalent among female Chinese university students and not uncommon among male students. Management of negative EE should be included as a component of university mental health promotion programmes in the region.

A cross-country examination of emotional eating, restrained eating and intuitive eating: Measurement Invariance across eight countries

This study examined the measurement invariance of three scales that assessed emotional eating, restrained eating, and intuitive eating across eight countries (Australia, Belgium, Canada, China, Italy, Japan, Spain and the United States) in order to determine their suitability for cross-country body image research. A total of 6272 young adults took part in this study. Participants completed an online survey including the Emotional Eating subscale of the Three Factor Eating Questionnaire-Revised 21, the Restraint subscale of the Eating Disorder Examination Questionnaire, and the Reliance on Hunger and Satiety Cues subscale of The Intuitive Eating Scale-2. Multi-group confirmatory factor analysis was used to evaluate potential cross-country differences in functioning of the measures. Partial invariance for all three scales was found, with only minor levels of non-invariance identified. Multiple indicator multiple cause models identified BMI and gender as potential influences on scores for these measures. Sources of invariance across groups are discussed, as well as implications for further substantive research across countries involving these measures.
