Benefits of yoga in the treatment of eating disorders: Results of a randomized controlled trial

Exercise and mind-body exercise for feeding and eating disorders: a systematic review with meta-analysis and meta-regressions

PURPOSE

To develop a systematic review with meta-analysis to summarize the effectiveness of exercise, regular physical activity, and mind-body exercise on harmful exercise habits, psychological factors, and quality of life in people clinically diagnosed with feeding and eating disorders.

MATERIAL AND METHODS

Randomized clinical trials and pilot randomized clinical trials were considered.

RESULTS

Twelve studies were included. No studies evaluated athletes. No studies examined regular physical activity as the targeted intervention. Quality of life could not be meta-analyzed. Overall, meta-analyses showed that exercise or mind-body exercise was not more effective than controls in reducing depression symptoms, harmful exercise habits, eating behaviors, or emotional regulation skills. However, important methodological and clinical issues were detected in the included studies. This affected the certainty of evidence of the meta-analyzed outcomes which ranged from low to very low. No studies reported in sufficient detail their interventions to be replicated.

CONCLUSIONS

Overall, exercise and mind-body exercise may be ineffective in improving meta-analyzed outcomes. However, the certainty of evidence ranged from low to very low and the body of knowledge in this field needs to be increased to reach robust conclusions.

Mechanisms of improved body composition among perimenopausal women practicing Meditative Movement: a proposed biobehavioral model

OBJECTIVES

Weight gain and unfavorable body composition are prevalent among midlife/older women throughout menopause. These shifts may negatively impact health, well-being, and longevity. Efforts to attenuate weight and body composition changes are traditionally driven by manipulation of diet and/or exercise; however, sustained results are limited, possibly because the full spectrum of biobehavioral systems is not addressed by diet and exercise alone. We propose a biobehavioral model detailing mechanisms of body composition decline among perimenopausal women and the associated components of Meditative Movement (ie, tai chi, qigong, yoga) that address each of these factors.

METHODS

Based on our previous work and extensive review of the literature, we developed a multifactorial and multidimensional biobehavioral model including factors that most directly relate to body composition among perimenopausal women: 1) psychological (ie, stress and mood, mindfulness and self-compassion, body awareness), 2) behavioral (ie, sleep, physical activity, eating behaviors), and 3) physiological (ie, cortisol, estrogen). Relationships between each factor, Meditative Movement practice components, and predicted effects on body composition were explored in detail.

RESULTS

Our model describes select psychological, behavioral, and physiological factors, and potential mechanistic pathways of Meditative Movement practice driving improved changes in body composition and weight outcomes for perimenopausal women.

CONCLUSIONS

The proposed model details a novel, evidence-supported means to reduce the risk of deleterious shifts in body composition throughout perimenopause and menopause thereafter. We suggest that these changes may occur directly and/or indirectly through psychological, behavioral, and physiological mechanisms that facilitate the desired changes in body composition.

Yoga as an adjunct treatment for the eating disorders: A qualitive enquiry of clinician perspectives

BACKGROUND

Yoga has been recognised as a beneficial adjunct for eating disorder (ED) treatment due to demonstrating positive effects on ED symptomology. Despite this, research exploring the perspectives of clinicians regarding the use of yoga for the spectrum of the EDs is limited. Consequently, this study utilised qualitative enquiry to explore the experiences and perspectives of clinicians regarding the implementation of yoga as an adjunct for ED treatment. This research examines how yoga may be safely applied for the EDs, to enhance ED treatment approaches and recovery.

METHODS

This study employed semi-structured interviews with 12-clincians with up to 20-years of experience working therapeutically with people with EDs. Participants were asked their perspectives on the benefits, risks, and adaptations for delivering safe and suitable yoga programs for the spectrum of EDs. Template thematic analysis was used.

RESULTS

Four distinct themes were identified. They included the (1) benefits of yoga, (2) risks associated with the practice, (3) recommendations for adapting yoga for this cohort, and (4) implementing yoga alongside current psychological treatment.

CONCLUSIONS

Clinicians viewed yoga as a safe and suitable transdiagnostic treatment, with the potential to support individuals with a more holistic and sustained recovery model. Clinicians raised concerns that might arise with the use of yoga for this cohort, however, they also emphasised the ability for these to be mitigated with a series of key adaptations. Importantly, clinicians recommended that yoga is implemented and monitored alongside ED treatment to ensure its suitability and safety. Key barriers for implementing yoga as an adjunct treatment and future research directions are discussed. Recent research has explored the benefits of yoga for individuals with eating disorders (EDs). However, researchers have not yet interviewed clinicians who work with those with EDs regarding their views on using yoga for their clients. This study therefore interviewed 12 clinicians working with individuals with EDs, to obtain their views for using yoga as a therapeutic treatment for this group. Overall, clinicians viewed yoga as a safe and beneficial treatment for EDs. While some concerns were raised regarding the safety of yoga for this group, clinicians emphasised that these could be relieved by a series of key adaptations. This study offers unique insights into how yoga may be safely applied into the care for ED clients, to enhance their treatment approaches and recovery.

One size may not fit all: A mapping review of yoga-based interventions for the treatment of eating disorders

BACKGROUND

While research investigating the potential benefits of yoga for eating disorders (EDs) has expanded, a systematic approach examining how yoga has been implemented for this cohort has not yet been conducted. This research therefore aimed to synthesize the current understanding of how yoga has been implemented for individuals with EDs, with regards to the feasibility, acceptability, and safety of yoga for this cohort.

METHODS

This study utilised mapping review technology. The following electronic databases were searched within the month of September 2021 and December 2022: PsycINFO, MEDLINE, CINAHL, and Embase. Articles that applied and documented the use of yoga for the EDs were selected.

RESULTS

The review identified ten unique studies. Details regarding the application, feasibility, acceptability, and safety of these yoga programs were extracted. This resulted in an evidence map or visual summary of how yoga has been applied for the EDs.

CONCLUSION

While limited, the current literature suggests that yoga is a safe, acceptable, and feasible transdiagnostic intervention for EDs. These findings provide pragmatic support for safely applying yoga for the EDs into clinical practice to support ED recovery.

A scoping review of integrated yoga and psychological approaches for the treatment of eating disorders

BACKGROUND

Eating disorders are serious mental health conditions that significantly impact the social and economic burden of mental ill health in Australia. Best practice treatment for eating disorders includes a multi-axial approach, including medical, psychiatric, and psychological approaches. More recently, complementary and alternative therapy approaches, such as yoga, are used to support eating disorder recovery.

METHODS

This scoping review identified and examined current research exploring the use of yoga alongside psychological approaches for the treatment and management of eating disorders across the lifespan.

RESULTS

Results highlighted the lack of available research, with only four studies identified. Three of these studies piloted programs and identified promising results with a reduction of eating disorder symptomatology. However, these results remain tentative due to methodological limitations and the overall lack of available evidence. In the future, researchers are encouraged to clearly articulate the theoretical concepts that underpin their yoga programs and focus on adequately powered and designed trials, such as RCTs, to accurately compare treatment effects between interventions combining yoga with psychological interventions and standard psychological treatment. Qualitative enquiry is also recommended to provide further insights regarding what makes interventions successful.

CONCLUSIONS

Current evidence suggests further guidance and pragmatic recommendations to guide researchers and clinicians alike are required, ultimately improving outcomes for people experiencing an eating disorder across the lifespan.

Complementary and Integrative Medicine and Eating Disorders in Youth: Traditional Yoga, Virtual Reality, Light Therapy, Neurofeedback, Acupuncture, Energy Psychology Techniques, Art Therapies, and Spirituality

Eating disorders (EDs) are a non-heterogeneous group of illnesses with significant physical and mental comorbidity and mortality associated with maladaptive coping. With the exception of lisdexamfetamine (Vyvanse) for binge eating disorder, no medications have been effective for the core symptoms of ED. ED requires a multimodal approach. Complementary and integrative medicine (CIM) can be helpful as an adjunct. The most promising CIM interventions are traditional yoga, virtual reality, eye movement desensitization and reprocessing, Music Therapy, and biofeedback/neurofeedback.

Efficacy of Eat Breathe Thrive: A randomized controlled trial of a yoga-based program

Evidence positions yoga as a promising intervention for enhancing positive embodiment and supporting the prevention of, and recovery from, eating disorders (EDs) by reducing ED symptomatology and building skills that facilitate an ongoing, embodied sense of wellbeing. However, yoga-based programs are few and rigorous literature on their efficacy is limited. This study examined the efficacy and feasibility of a yoga-based program called Eat Breathe Thrive (EBT) which aims to prevent EDs and support embodiment. Participants (N = 168, 93.5 % women) from a community sample in the United States and United Kingdom, ages 18-65, were randomly allocated to a 2-h, 7-week EBT program or waitlist-control condition. Compared to controls, EBT participants experienced significant decreases in ED behaviors, depression, and difficulties regulating emotions. They reported significantly greater use of mindfulness skills, such as interoceptive awareness, mindful self-care, and mindful eating. After a single session, participants reported immediate improvement in their sense of well-being, indicating increased state positive embodiment. Most effects were sustained at 6-month follow-up. The majority of individuals attended most sessions. Self-reported treatment integrity was excellent. Directions for future research are proposed. Results support the efficacy and feasibility of an integrated yoga intervention that fosters positive ways of inhabiting the body.

Indigenous psychology in Africa: Centrality of culture, misunderstandings, and global positioning

I present here an assessment of African Psychology (AP) to give insights about how it has been conceptualised and practised thus far as well as what its future holds. I begin with a focus on the centrality of culture and how AP treats the concept of culture. I will then attempt to respond to some concerns often raised by Africa-based psychologists who do not operate in and from a multiracial space about the relevance and legitimacy of AP. Theoretically, multiracial space is conceptualised not to mean the mere presence of people from diverse races in a particular space but also to the uneven distribution of power in spaces such as a country, state, university, or any community of people. Further, I attempt to argue for positioning of AP to contribute to global psychology. I will discuss implications for theory development, practice, curriculum design, and pedagogical practices as well.

Yoga as an Integrative Therapy for Mental Health Concerns: An Overview of Current Research Evidence

Background: Because the prevalence of mental health concerns is high and access or full responsiveness to pharmacological or psychotherapeutic treatment for many individuals is low, there has been increased interest in yoga as a potential therapy for many mental health concerns. Approach: We synthesize and critique current research on the efficacy of yoga relative to pharmacological approaches for anxiety disorders, mood disorders, posttraumatic stress disorder, obsessive-compulsive disorder, and eating disorders. Results: Yoga has been tested mostly as a complementary treatment to standard psychiatric and psychotherapeutic approaches. Findings from efficacy trials largely support the notion that yoga can help reduce symptoms of many psychiatric conditions, including anxiety, depression, and PTSD symptoms, above and beyond the effects achieved by standard pharmacological treatments alone; however, most evidence is of poor to moderate quality. Plausible transdiagnostic bottom-up and top-down mechanisms of yoga’s therapeutic effects have been advanced but remain untested. Conclusions: While results should be considered preliminary until more rigorous evidence is available, yoga appears to have the potential to provide many people suffering with psychiatric symptoms additional relief at relatively little cost. Yoga may be a viable complementary therapy to psychiatric and psychotherapeutic approaches for people with mental health challenges.

Updates in the treatment of eating disorders in 2020: a year in review in eating disorders: the journal of treatment & prevention

Several important studies advancing treatment of eating disorders were published in Eating Disorders: The Journal of Treatment & Prevention in 2020. This review summarizes the recent contributions to the literature on the treatment of eating disorders, including dialectical behavior therapy, yoga for positive embodiment, and treatment innovations in children and adolescents with eating disorders. Dialectical behavior therapy can be effectively used in complex eating disorder presentations, such as with comorbid substance use disorder and with suicidal behavior, and can be adapted for culturally-responsive treatments for binge eating and for guided self-help. Yoga may promote positive embodiment, which is supported by conceptual frameworks, studies evaluating yoga treatment interventions, and systematic reviews. Advances in eating disorder treatment for children and youth include the development of the Emotional Eating Scale adapted for children and adolescents, a review of primary care interventions for eating disorder treatment, and siblings' perspectives on eating disorder treatment. Research on novel methods including telementoring and innovative treatment modalities invoking feminism are promising areas of future research.

Yoga practice among ethnically/racially diverse emerging adults: Associations with body image, mindful and disordered eating, and muscle-enhancing behaviors

BACKGROUND

This study explores cross-sectional associations between yoga and body image, mindful eating, disordered eating, and muscle-enhancing behaviors among a population-based sample of ethnically/racially diverse emerging adults.

METHOD

An ethnically/racially diverse population-based sample of 1,568 emerging adults (18-26 years) completed surveys as part of EAT 2010-2018 (Eating and Activity over Time). Models were adjusted for sociodemographic characteristics and body mass index (BMI).

RESULTS

Practicing yoga at least 30 min/week was reported by 12.7% (n = 210) of the sample. Yoga practitioners had higher levels of mindful eating than those not practicing yoga. Although effect sizes were small, yoga practitioners were more likely than non-yoga practitioners to use steroids (3.8 vs. 0.7%, p < .001, h = 0.22) or protein powder/shakes (35.1 vs. 25.3%, p < .010, h = 0.21) to increase their muscle size/tone. Body satisfaction, unhealthy weight control behaviors, and binge eating tended to be similar among yoga practitioners and non-yoga practitioners. There was a significant interaction between BMI and yoga in predicting body satisfaction with a trend toward a positive impact among yoga practitioners at higher BMI values. Interactions between yoga practice and all body image attitudes and behaviors across gender and ethnicity/race were not statistically significant.

DISCUSSION

Young people from diverse ethnic/racial backgrounds who practice yoga are more likely to engage in mindful eating but have equal or elevated levels of unhealthy body image attitudes and behaviors as compared to non-yoga practitioners. Further research should explore how yoga is best taught and practiced to ensure that it is beneficial for body image and related behaviors.

Introduction to the special issue on yoga and positive embodiment: a note from the editors on how we got here

Studying the practice of yoga and its relationship to body image, embodiment, and eating disorders brings together the professional and personal aspects of our lives as yoga practitioners, researchers, and women living in bodies within a society that can be tough on body appreciation. Developing this edition on "Yoga for positive embodiment in eating disorder prevention and treatment" has been a work of love for all of us. As yoga practitioners, we have personally experienced the benefits of yoga in our own bodies and felt that there may be benefits for others. As researchers, we are dedicated to the exploration and utilization of evidence-based practices to enhance well-being, promote a positive body image and sense of embodiment, and both prevent and treat eating disorders. Our experiences as yoga practitioners, in conjunction with our curiosity as researchers, led us to explore the extant evidence for yoga as a tool for leading to improvements in body image, disordered eating behaviors, and eating disorders, and to embark on our own research in this area to fill necessary gaps in our knowledge base. Our long-term dedication to the fields of body image and eating disorders, in conjunction with our emerging interest in yoga as a potential tool, led us to the compilation of this edition on yoga and positive embodiment.

Yoga and eating disorder prevention and treatment: A comprehensive review and meta-analysis

Yoga is frequently used in conjunction with standard treatment approaches for eating disorders. However, yoga's efficacy and effectiveness in preventing and treating eating disorders has remained unclear. The aim of this comprehensive review and meta-analysis is to review the extant literature and assess the effects of yoga in the prevention and intervention of eating disorder symptoms and correlates in both clinical and non-clinical populations. Studies assessing yoga and its effect on eating disorder symptoms and/or body image as related to disordered eating, were eligible for inclusion. The comprehensive review details correlational, non-controlled, non-randomized controlled, and yoga comparison studies. For the meta-analysis, only randomized controlled trials comparing a yoga-based intervention to a non-yoga control group were included. In total, 43 studies are included in this review, with 11 trials involving 754 participants included in the meta-analysis. Results of the comprehensive review and meta-analyses results indicated yoga interventions demonstrated a small, significant effect on global eating disorder psychopathology, a moderate-to-large effect on binge eating and bulimia, and a small effect on body image concerns, as compared to the control conditions. There was no statistically significant effect on dietary restraint in either direction. Additionally, results indicated a small-to-moderate effect on a composite measure of eating disorder-related constructs. These findings suggest that yoga-based interventions may be an effective approach supporting the prevention and treatment of eating disorders.
