Eating Disorders and Obesity: The Challenge for Our Times

Intuitive tracking: Blending competing approaches to exercise and eating

Under the conditions of neo-liberal individual responsibilisation, self-tracking has become the predominant model of health management. More recently, though, intuition-based approaches to exercise and eating are also gaining traction. These two approaches are often located in opposition. While self-tracking uses datafication and calculability to structure health decisions, intuitive approaches encourage abandonment of rules and restrictions around exercise and food in favour of corporeal self-awareness and attunement to sensation. Although navigating these competing approaches is a common experience for all populations, the tensions between them are felt particularly acutely by people with complex health histories, such as eating disorders (EDs). In this article, we draw on mixed-methods longitudinal data, analysed using phenomenological analysis, to propose a novel framework - 'intuitive tracking'-which moves beyond understandings of self-tracking as the antithesis of intuitive engagement with exercise and health. Drawing on longitudinal interviews and photo elicitation with 19 women who are in recovery from EDs and using weightlifting as a tool to support their recovery, we demonstrate how attentiveness to bodily and emotional cues is successfully combined with an emphasis on monitoring health behaviours to support wellbeing. We conclude that theoretical understandings of self-tracking can and should make space for intuition-led decision-making.

Eating disorder risks and psychopathological distress in Italian high school adolescents

BACKGROUND

Psychopathological disorders are often comorbid diagnosis in eating disorders (EDs). We aimed to assess the presence of psychopathological traits and symptoms associated with EDs in an Italian high school adolescent population.

METHODS

A sample of high school adolescents was enrolled, and demographic and clinical data were collected. Two self-report questionnaires, the Eating Disorder Inventory-3 (EDI-3) and the Questionnaire for the Assessment of Psychopathology in Adolescence (Q-PAD), were administered.

RESULTS

548 adolescents (333 F/215 M; 16.89 ± 0.85 years) were included. Symptoms associated with EDs of clinical or high clinical concern were prevalent in a range of individuals, with percentages varying from 26.82% for body dissatisfaction to 51.83% for Interoceptive Deficits. The findings from the Q-PAD assessment indicated the presence of psychological distress, leading to discomfort or challenging situations requiring potential intervention in a percentage of adolescents ranging from 2.93% for psychosocial risks to 23.77% for anxiety. These percentages showed differences between genders (F > M, p < 0.001). Our study also highlighted an association between symptoms of EDs and lifestyle factors within families. We observed correlations between Q-PAD measures and EDI-3 scores, including a positive correlation between Q-PAD and EDI-3 body dissatisfaction (r = 0.7), Q-PAD interpersonal conflicts and EDI-3 interpersonal problems (r = 0.6) and a negative correlation between Q-PAD self-esteem and well-being and EDI-3 ineffectiveness Composite (r=-0.7).

CONCLUSIONS

a substantial prevalence of ED symptoms and psychological distress among high school adolescents were recorded. These conditions are interrelated, suggesting the importance of addressing them comprehensively. Early detection is essential to improve treatment outcomes and to implement preventive strategies.

Eating Styles Profiles and Correlates in Chinese Postpartum Women: A Latent Profile Analysis

Postpartum women present a high risk of disordered eating behaviors, but the heterogeneity between groups was not identified. This cross-sectional study aimed to identify eating styles profiles in postpartum women and explore the correlates based on demographic characteristics and psychosocial factors. Questionnaires were administered to 507 Chinese postpartum women. Latent profile analysis (LPA) was conducted to identify eating styles profiles. Multinomial logistic regression was used to investigate the correlates of these profiles among postpartum women. The LPA identified three eating styles profiles: postpartum women with low emotional, external, and restrained eating (Profile 1, 6.9%); postpartum women with medium emotional, external, and restrained eating (Profile 2, 66.1%); and postpartum women with high emotional, external, and restrained eating (Profile 3, 27.0%). Compared to Profile 1, higher postpartum depression (PPD) and body mass index (BMI) were more likely to be associated with Profile 2 and Profile 3, whereas higher postpartum weight retention (PPWR) was more likely to be associated with Profile 1. Compared to Profile 2, higher PPD and BMI were more likely associated with Profile 3. Disordered eating behaviors in postpartum women with three eating styles were associated with BMI, PPD, and PPWR. This study can guide healthcare professionals in developing targeted interventions to improve maternal and child health globally.

Dismantling the myth of "all foods fit" in eating disorder treatment

We call for a reevaluation of the long-standing dogmatic nutritional principle that "all foods fit" for all cases of eating disorders (EDs) and its corollary, "there are no bad foods" (for anyone ever) during ED treatment. Based on accumulated scientific research, we challenge these ideologies as outdated, confusing, and potentially harmful to many patients. We review the evidence that indicates the folly of these assumptions and show there are a variety of exceptions to these rules, including (1) food allergies, sensitivities, and intolerances, (2) religious and spiritual preferences or doctrines, and (3) the ubiquitous emergence and widespread availability of ultra-processed foods leading to the potential development of addiction-like eating and a higher prevalence of various medical and psychiatric comorbidities, as well as higher mortality. This evidence supports a nutritional psychiatry approach that should be integrated into (rather than dissociated from) ED treatment research and practice.

Eating disorders and obesity: bridging clinical, neurobiological, and therapeutic perspectives

Eating disorders (EDs) and obesity are complex health conditions sharing various risk and maintenance factors, intensified in cases of comorbidity. This review explores the similarities and connections between these conditions, examining different facets from a multidisciplinary perspective, among them comorbidities, metabolic and psychological factors, neurobiological aspects, and management and therapy implications. We aim to investigate the common characteristics and complexities of weight and EDs and explore their interrelationships in individuals who experience both. The rising prevalence of EDs in people with obesity necessitates integrated approaches to study this comorbidity and to identify and analyze both common and distinct features of these conditions. This review may offer new opportunities for simultaneous prevention and management approaches, as well as future lines of research.

Media Literacy Practices to Prevent Obesity and Eating Disorders in Youth

PURPOSE OF REVIEW

Obesity and eating disorders share common issues related to media use and effects, especially in the USA. Current research increasingly demonstrates that media literacy can address this problem. This narrative review highlights current media literacy-based research for obesity and eating disorder prevention among youth.

RECENT FINDINGS

Current research using media literacy techniques to prevent obesity indicates that these interventions improve nutrition outcomes, improve family communication about food, improve critical thinking about food advertisements, reduce sugar and fat intake, and reduce screen use for parents and youth. In addition, eating disorder research reveals that media literacy techniques lead to higher scores of body satisfaction and self-esteem, with lower scores of perfectionism, thinness, and ideal masculinity. There is a need for media literacy-based interventions to focus on family communication to prevent obesity and eating disorders. Furthermore, there should be more focus on identified levels of prevention and specific clinical outcomes.

Very low-calorie ketogenic diet in the treatment of adaptive thermogenesis: A case report

OBJECTIVES

The management of the phenomenon of adaptive thermogenesis poses a challenge to the successful treatment of overweight/obesity with a nutritional intervention that minimizes the loss of muscle mass, with little cognitive restraint use and disorganization of eating behavior. On the other hand, it creates a significant calorie deficit for the reduction of body fat. The aim of this case report was to discuss the effects of a very low-calorie ketogenic diet in a woman with obesity and low resting metabolic rate.

CASE DESCRIPTION

A 36-y-old white woman with a history of obesity and bulimia nervosa who has had difficulty losing and maintaining weight despite numerous dietary and pharmacologic treatments.

RESULTS

There was a loss of 12 kg in 115 d, reaching 13.4 kg, with 11.4 kg of fat mass (FM). The resting metabolic rate showed an increase of 79% in relation to the initial rate, reaching normal levels for the predictive equations and maintaining this level in the first-year follow-up. Additionally, improvement of metabolic laboratory parameters and eating behavior traits were described.

CONCLUSIONS

In this specific case of bulimia nervosa resulting in hypometabolism (low resting metabolic rate/fat-free mass) and obesity, the very low-calorie ketogenic diet intervention has demonstrated a possibility of weight loss with little cognitive restraint use, thereby increasing resting metabolic rate in the short and medium terms, ultimately promoting a negative energy balance. In relation to the numeric results, it seems positive; however, more research is necessary to evaluate the effects on the overall relationship with food and its long-term repercussions.

Individuals with restrictive eating disorders' experience of the introduction of calories on menus in England: An interpretative phenomenological analysis study

OBJECTIVE

In April 2022 the Calorie Labelling (Out of Home) Regulations came into effect in England where cafés, restaurants, and takeaways with over 250 employees were required to provide calorie labelling on menus. Concerns have been raised regarding the potential negative impact this could have on individuals with eating disorders (EDs), yet this has not been explored using qualitative methodology.

METHOD

Eleven participants with a current or previously diagnosed restrictive ED were interviewed in September 2022. Interpretative Phenomenological Analysis (IPA) was used to explore their experience of the introduction of calories on menus.

RESULTS

Using IPA we established six themes and seven subordinate themes. These included the introduction of calories on menus as an 'attack' on individuals with EDs; the prominent visual display of calories as an attentional pull; normalising of calories counting; the impact on behaviour; and associated strategies for managing.

CONCLUSION

This contributes to research surrounding the implications for public health policies on individuals with EDs, especially their ability to reinforce and amplify disordered thoughts and behaviours, and the need for greater consideration of how to minimise impact and potential harm of large public health campaigns.

Thyroid dysfunction in children and adolescents affected by undernourished and overnourished eating disorders

Eating disorders (ED) are one of the most prevalent chronic disorders in adolescents and young adults, with a significantly increasing prevalence in younger children, particularly in girls. Even if obesity in essence is not framed as an eating disorder and has always been considered a separate pathology, ED and obesity could be considered part of a continuum. It has become evident that one condition can lead to another, such as binge eating disorder (BED) and bulimia nervosa, and that they share the same repercussions in terms of psychosocial, metabolic, and nutritional health. This narrative review aims to investigate the hypothalamic-pituitary-thyroid axis in undernourished and overnourished patients with ED, including obesity, in order to highlight the relationship between weight control and thyroid function and its effects and to consider therapeutic and preventive strategies in children and adolescents. Literature data report that thyroid alterations occur in patients with ED, both underweight and overweight, and represent a continuum of changes depending on the severity and time course of the disease involving the endocrine system. Considering the relevant role thyroid hormones (TH) play not only in energy expenditure (EE) but also in metabolic control and cardiovascular risks related to dysmetabolism and mood regulation, continuous monitoring of thyroid homeostasis in patients with ED is mandatory to prevent severe complications and to start early treatment when necessary.

Specific Learning Disorders in Children and Adolescents with Obesity

Specific learning disorders (SLDs) are the most frequently diagnosed developmental disorders in childhood. Different neurocognitive patterns have been found in patients with overweight and obesity, but no data on childhood obesity and SLDs have been reported. To increase our understanding of the relationship between neuropsychological developmental and obesity, we assessed the prevalence of SLD in a pediatric population with obesity. We retrospectively included 380 children and adolescents with obesity. For all participants, auxological, metabolic, demographic features, relationship and social skills, anamnestic data on pregnancy and the perinatal period, stages of development and family medical history were reviewed. SLD was defined according to the DSM-5 criteria. A group of 101 controls of normal weight was included. The overall prevalence of SLD was 10.8%, and SLD was more prevalent in patients with obesity (p < 0.001), with male predominance (p = 0.01). SGA was associated with SLD (p = 0.02). Speech retardation (p < 0.001), limited relationships with peers (p < 0.001) and didactic support (p < 0.001) were noted in the SLD group compared to the group without SLD. A higher prevalence of family history of neuropsychiatric disorders was observed in the SLD group (p = 0.04). A higher fasting glucose level was detected in patients with obesity and SLD compared to subjects without SLD (p = 0.01). An association between obesity and SLD could not be excluded, and an overlap of pathogenic factors for both conditions should be considered.

Mediating effects of a weight-inclusive health promotion program on maladaptive eating in women with high body mass index

Research shows that individuals with a body mass index (BMI) over 30 have experienced an 11-fold increase in restrictive eating and a 7-fold increase in binge eating since the 1990s. Most health promotion programs for higher-weight individuals have not been developed with the high eating disorder risk for this population in mind. The purpose of current study was to test two hypothesized mechanisms underlying improvement in maladaptive eating patterns shown in a weight-inclusive health promotion program designed for women with BMIs at or above 30. Participants (N = 40) were primarily White (93 %), 30-45 years old (M = 39.83, SD = 4.34) with BMIs ranging from 30 to 45 kg/m² (M = 37.42, SD = 3.58). Using the MEMORE macro, we tested a parallel mediation model hypothesizing that internalized weight stigma and intuitive eating would explain improvements on two subscales from the Three-Factor Eating Questionnaire-R18 after a 6-month program. Total effects of the program on uncontrolled (b = -3.76, SE = 0.64, p < .0001) and emotional eating (b = -1.79, SE = 0.34, p < .0001) were significant. The indirect effects (IE) of internalized weight stigma on uncontrolled eating (IE = 1.59, SE = 0.79, 95 % CI = 0.46, 3.49) and emotional eating (IE = 0.67, SE = 0.40, 95 % CI = 0.11, 1.68) were also significant. Likewise, the IEs of intuitive eating on uncontrolled eating (IE = 2.09, SE = 0.70, 95 % CI = 0.60, 3.38) and emotional eating (IE = 1.03, SE = 0.43, 95 % CI = 0.08, 1.82) were significant. These findings indicate that weight-inclusive health promotion programs that directly address weight bias and eating according to cues from the body may help higher-weight individuals improve maladaptive eating patterns via reductions in internalized weight stigma and increases in intuitive eating.

Development of the Menu Assessment Scoring Tool (MAST) to Assess the Nutritional Quality of Food Service Menus

Preventing the rise in obesity is a global public health priority. Neighbourhood environments can help or undermine people's efforts to manage their weight, depending on availability of nutritious and nutrient-poor 'discretionary' foods. The proportion of household food budgets spent on eating outside the home is increasing. To inform nutrition policy at a local level, an objective assessment of the nutritional quality of foods and beverages on food service menus that is context-specific is needed. This study describes the development and piloting of the Menu Assessment Scoring Tool (MAST), used to assess the nutritional quality of food service menus in Australia. The MAST is a desk-based tool designed to objectively assess availability of nutrient-poor and absence of nutritious food and beverages on food service menus. A risk assessment approach was applied, using the best available evidence in an iterative way. MAST scores for 30 food service outlets in one Local Government Authority in Perth, Western Australia highlight opportunities for improvements. MAST is the first tool of its kind in Australia to assess the nutritional quality of food service menus. It was practical and feasible to use by public health nutritionists/dietitians and can be adapted to suit other settings or countries.

The relationship between the high-risk disordered eating and social network navigation among Saudi college females during the COVID pandemic

Background

Disordered eating behaviors (DEBs) are complex health issues that may lead to negative physical and mental health outcomes among college students. More studies should be directed toward the screening of DEBs. This study aimed to determine the prevalence of DEBs among Saudi female university students and their association with social networking site (SNSs) usage and composite lifestyle behaviors during the unprecedented period of COVID-19.

Methods

This cross-sectional study included 445 females recruited using stratified random sampling. The participants self-reported demographic, social, medical, and lifestyle data and completed the validated Arabic version of the Eating Attitudes Test-26, Social Networking Sites (SNSs) Usage Questionnaire, Bergen Social Media Addiction Scale, and Body Shape Questionnaire.

Results

The prevalence of DEBs was 27.2% among the female students at Taif University. From the pre-pandemic period until the current time, the DEBs-risk group had a significantly higher SNS navigation rate (36.4%) than the normal group (20.4%) (X ² = 30.015, p = 0.001). The regression analysis revealed that females with a significant body image concern, higher number of SNSs friends, and frequent visits to SNSs, and those seeking social-dependent information in relation to weight loss/dieting were more likely to develop DEBs (Overall Model: Chi-Square X ² = 158.071, p < 0.000^**).

Conclusions

SNSs usage and DEBs were associated during the COVID-pandemic. However, the composite lifestyle score did not demonstrate a significant association with DEBs among the female students at Taif University. Investigating the magnitude of DEBs and understanding the role of SNS are essential for preventing disordered eating among young females.

Eating disorders among women in primary care (Monastir, Tunisia)

INTRODUCTION

Eating disorders (ED) are relatively frequent, but convey a high mortality and morbidity. More than half of individuals with ED remain undetected in primary care. The general practitioners (GP) are in a strategic position to detect patients with ED.

AIMS

To determine the prevalence of ED in Tunisian women visiting their GP using the SCOFF-F score and to determinate the associated socioeconomic, clinical, and lifestyle factors.

METHODS

This is a cross-sectional study of women who consulted two primary health care in the city of Monastir, during 4 months of the year 2020. The SCOFF-F was performed.

RESULTS

We included 445 women; the mean age of our patients was 36 ± 12 years. SCOFF-F was positive in 48% of cases CI95% [43-52%], 14% presented with bulimia nervosa and 12% with binge eating disorder. Patients with ED were overweight in 33% of cases, 40% perform a physical activity and 53% eat three meals per day. A family history of ED was 35%. 20% of the patients have a history of psychiatric disorder. In multivariate analysis, performing physical activity to control weight, eating three meals a day, maintaining the current diet without trying to change into a different one, non continous occupation and anxiety increase the risk of ED with respective ORs of 2.34, 4.26, 3.69, 2.09 and 2.09 respectively. Ages between 35 and 60 years, and a history of ED in siblings increases the risk of ED by 1.6.

CONCLUSION

Our study concluded that ED was associated with common family behavior, especially among siblings, and with a particular psychological state which are interesting to screen by GP and to focus on targeting family care.

Obesity and Eating Disorders in Children and Adolescents: The Bidirectional Link

Obesity, eating disorders and unhealthy dieting practices among children and adolescents are alarming health concerns due to their high prevalence and adverse effects on physical and psychosocial health. We present the evidence that eating disorders and obesity can be managed or prevented using the same interventions in the pediatric age. In the presence of obesity in the pediatric age, disordered eating behaviors are highly prevalent, increasing the risk of developing eating disorders. The most frequently observed in subjects with obesity are bulimia nervosa and binge-eating disorders, both of which are characterized by abnormal eating or weight-control behaviors. Various are the mechanisms overlying the interaction including environmental and individual ones, and different are the approaches to reduce the consequences. Evidence-based treatments for obesity and eating disorders in childhood include as first line approaches weight loss with nutritional management and lifestyle modification via behavioral psychotherapy, as well as treatment of psychiatric comorbidities if those are not a consequence of the eating disorder. Drugs and bariatric surgery need to be used in extreme cases. Future research is necessary for early detection of risk factors for prevention, more precise elucidation of the mechanisms that underpin these problems and, finally, in the cases requiring therapeutic intervention, to provide tailored and timely treatment. Collective efforts between the fields are crucial for reducing the factors of health disparity and improving public health.

The Controversial Role of Adiponectin in Appetite Regulation of Animals

Eating disorders and obesity are important health problems with a widespread global epidemic. Adiponectin (AdipoQ), the most abundant adipokine in the plasma, plays important roles in the regulation of energy homeostasis, glucose metabolism and lipid metabolism. Plasma adiponectin concentration is negatively associated with obesity and binge eating disorder. There is a growing interest in the appetite regulation function of adiponectin. However, the effect of AdipoQ on feeding behavior is controversial and closely related to nutritional status and food composition. In this review, we summarize the literatures about the discovery, structure, tissue distribution, receptors and regulation of nutritional status, and focus on the biological function of adiponectin in the regulation of food intake in the central and peripheral system.

Self-reported symptoms of binge-eating disorder among adolescents in a community-based Danish cohort-A study of prevalence, correlates, and impact

OBJECTIVE

Binge-eating disorder (BED) was established as a diagnosis in 2013 with the DSM-5 and has been included in the ICD-11 in 2018. In adulthood, BED is prevalent and correlated with somatic and mental health problems. Less is known about BED in adolescence, although this age period could represent a window of opportunity for early intervention. This study aimed to investigate the 1-year prevalence, correlates, and impact of BED symptoms in a community sample of adolescents.

METHOD

We included 1,404 girls and 1,105 boys from the 16-years-follow-up of the Copenhagen Child Cohort study, CCC2000. The adolescents self-reported on BED symptoms, weight-status, body perception, mental health problems, and self-rated impact of food and weight-related thoughts and behaviors. Information about socio-economic factors and hospital diagnosed psychiatric disorders were obtained from national registries.

RESULTS

A total of 8.5% reported weekly overeating with loss of control (10.9% of girls, 4.8% of boys), and 2.6% (3.6% of girls, 1.2% of boys) reported symptoms consistent with BED according to the DSM-5. Regardless of sex, BED was correlated with concurrent overweight, body-dissatisfaction, low self-esteem, and mental health problems, especially emotional, but also with problems of behavior, inattention, and peer-relations, and with high self-rated impact on everyday life. Immigrant background and lower socio-economy were potential risk factors for BED in boys in this sample.

DISCUSSION

BED was prevalent and correlated with mental health problems and overall impact among adolescents in this community sample, indicating the need for clinical attention and intervention towards binge-eating disorder in the adolescent period.

GLP1 analogues among patients with overweight or obesity during lockdown

BACKGROUND AND OBJECTIVES

One of the potential negative effects of a lockdown are changes in dietary and lifestyle patterns, which can lead to weight gain. Our objective was to assess the changes on dietary habits and eating patterns in a lockdown situation and their impact on weight. We aimed to determine whether the treatment with GLP1 analogues (aGLP1) could impact on these parameters.

MATERIAL AND METHODS

100 overweight/obese patients were consecutively recruited for a review at the end of the lockdown. A structured interview was designed to see changes in dietary habits, routines and exercise.

RESULTS

52% patients gained weight during lockdown. The percentage of subjects with an active history of depression or anxiety was higher among the group of patients who gained weight. The percentage of patients who worsened their hyperphagia was higher in those who gained weight (71.2% vs. 10.6%; P<0.0001); similar results were observed with binge eating (92% vs. 10.6%; p<0.0001) and cravings, both sweet and salty (69.2% vs. 21.3% and 69.2% vs. 14.9%; p<0.0001 and p<0.0001 respectively). Of the 48 patients who did not gain weight, 30 were under aGLP1 treatment (61.7%). The worsening of abnormal eating patterns was lower among patients treated with aGLP-1.

CONCLUSIONS

A lockdown is a vulnerable period to gain weight, especially in those patients with a psychopathological history. aGLP1 manage to control emotional eating, making them a valuable therapeutic option.

Have Our Attempts to Curb Obesity Done More Harm Than Good?

Dieting is a common method for weight loss, maintenance, and prevention of weight gain, but the harmful outcomes of dieting are understudied. Dieting is typically advised for obese patients for the sake of their health, though this does not account for the many complicated factors surrounding obesity. We conducted a search through the PubMed database on obesity, dieting, and eating disorders and did not limit the study by population or year. We found studies showing that although dieting may cause short-term weight loss, it is associated with weight gain in the long-term. We also found studies assessing the negative psychological and physical outcomes of dieting. Though there are many studies that emphasize the negative psychological impact of dieting, few studies have explored how dieting may contribute to the development of eating disorders in the obese. Studies on the physical impact of dieting were less conclusive but warrant further study. While it is difficult to draw any substantial conclusions from the data, our results showed that dieting may carry more risks than benefits as a means to lose weight.

The role of comorbidity in the association of obesity with unemployment and disability

PURPOSE

The association of obesity with a large range of physical conditions and numerous psychiatric disorders has been extensively studied. Our study sought the extent to which physical conditions or psychiatric disorders associated with obesity mediate the association of obesity with unemployment or disability.

METHODS

Using data from the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III, 2012-2013), we estimated the prevalence of unemployment as a function of obesity taking into account these comorbidities. Data on self-reported height and weight were available for 35,725 respondents. Clinician-diagnosed physical conditions were self-reported and lifetime psychiatric disorders were assessed with a semistructured interview.

RESULTS

The adjusted prevalence of obesity was 30.4%. Participants with obesity were more likely than participants without obesity to report at least one of the 31 assessed physical conditions (64.46% vs. 46.87%; P < .001). Participants with obesity were more likely to report at least one of the 24 assessed psychiatric diagnoses than respondents without obesity (60.57 vs. 56.75%; P < .001). The rates of unemployment were higher in participants with obesity than in those without obesity (15.75% vs. 11.26%; P < .001). Similarly, participants with obesity reported higher rates of disability than those without obesity. Although the number of physical conditions and psychiatric disorders partly explains this association, obesity remained significantly associated with unemployment and greater disability when controlling for the number of physical conditions and psychiatric disorders.

CONCLUSIONS

Obesity is associated with high rates of unemployment and with high disability. This is not explained solely by the high rate of physical conditions and psychiatric disorders associated with obesity.
