Are We There Yet? Progress in Depicting Diverse Images of Beauty in Instagram's Body Positivity Movement

Understanding Fitness Trends in the Virtual Age: A Content Analysis of TikTok Workout Videos

The purpose of this study was to examine the content of workout videos on TikTok. A sample of 297 TikTok workout videos was coded for demographic factors and body shape of content creators, as well as the presence of body positivity messaging, appearance-related messaging, and other relevant themes. The results suggest that TikTok workout content is often presented in a time-lapse format with little verbal instruction, which may make it difficult for viewers to perform the exercises. The majority of the videos depicted young women with athletic bodies and other characteristics associated with culturally based beauty ideals, and approximately half of the videos included non-White content creators. Approximately a quarter of the videos in the sample included objectification and a smaller proportion of the sample included messages about inner positivity. Overall, the TikTok platform may provide underrepresented individuals opportunities to seek out workout content from a more diverse group of instructors; however, the fact that many of these videos including objectifying depictions of the content creators is concerning. Further experimental work is needed in order to more fully elucidate the effects of TikTok workout videos on viewers.

State affect and body image effects of body positive social media content within a female chronic illness sample

Body positivity refers to a movement, popularized on social media, that encourages the normalization and acceptance of bodies diverging from sociocultural ideals, specifically within marginalized communities. Previous studies suggest that briefly viewing body positive social media content may lead to increased body satisfaction and positive affect in young women relative to thin-ideal and appearance-neutral content. Diminished body functionality and appearance change due to chronic illness poses a unique challenge to positive body image in young adults living with chronic illness. Typical body positive social media content may not be useful for this community since chronic illnesses are often not outwardly depicted, so the current study aimed to examine the state effects before and after viewing body positive social media content in a sample of young women (N=201) with at least one self-reported chronic illness. Participants (Mage = 29.4, SD = 6.74; 79.2 % white) were randomly assigned to view one of two sets of 10 images: chronic illness body positive and typical body positive. Participants completed a Visual Analogue Scale (VAS) pre- and post-stimuli exposure. Findings from repeated measures ANOVA revealed significant interaction between time and group for negative affect (F(1198) = 4.402, p =.037) and broad conceptualization of beauty (F(1199) = 4.288, p =.040), such that those exposed to the chronic illness stimuli reported a larger reduction in negative affect and an increase in conceptualization of beauty beyond the non-chronically ill ideal post-exposure. Thus, exposure to body positive social media content inclusive of chronic illness may be more useful in stabilizing affect and promoting greater positive body image within the community. These findings highlight the importance of inclusive body positive portrayals in terms of dimensions beyond weight and shape to account for the effects of diminished body functionality.

A Content Analysis of Social Media influencers' "What I Eat in a day" Vlogs on YouTube

Food diaries on social media, known as "what I eat in a day" (WIEIAD) content, are increasingly popular across a variety of platforms, and can potentially affect audiences' attitudes and behaviors regarding diet. WIEIAD content is frequently posted by social media influencers (SMI), who have powerful and persuasive effects on their audiences. Using expectancy-value and social norms as theoretical frameworks, this study examines characteristics of SMIs and the way they talk about diet. A mixed-methods content analysis of YouTube vlogs (n = 83) posted from October 2015 to October 2016, and October 2021 to October 2022 was conducted on SMIs who post WIEIAD vlogs. Results suggested that influencers may want to embrace body positivity, but their WIEIAD day content contains weight normative messaging. Furthermore, influencers send messages about what health should look like and assign social identities to specific diets. Aside from sponsorship, influencers use other persuasive strategies to grow large followers, such as listing positive expectancies of their diets. Future research should examine the effects of WIEIAD content on diet-related attitudes and behaviors.

Modeling body size information within weight labels using probability distributions

What images of bodies do we associate with thinness and fatness? Can our representations of weight-related words be described by simple probability distributions? To answer these questions, the present study examined participants' perceptions of a set of weight-related words using a pictural scale. 259 French women indicated the thinnest, fattest, and best-fitting figures for 13 words. We then used their responses to construct PERT probability distributions, simple skewed distributions allowing to visualize what body sizes were associated with each word. In particular, the variability of the distributions showed how different weight labels can have more or less precise meanings. We found some evidence that the lowest body mass index associated with a label shifted towards thinner figures as body dissatisfaction increased. Using the same method, we investigated the boundaries of what participants consider the ideal body, and showed that the inclusion of their own body in these boundaries predicted their levels of body dissatisfaction. We argue that PERT distributions can be a useful, easy-to-use tool in body image research for modeling the representations of weight labels in different populations.

Revisiting positive body image to demonstrate how body neutrality is not new

In this position paper, we review nonacademic and academic discourse on body neutrality, a recent concept that has spread from social media platforms into scientific publications. This discourse has (inaccurately) promulgated that body neutrality is distinct from and more realistic than positive body image and body positivity. We identify and challenge 10 myths found within this discourse: (1) positive body image and body positivity are the same and therefore interchangeable, (2) positive body image isn't realistic or attainable, (3) we should forget about body positivity and positive body image, (4) body neutrality is a new way of thinking about body image, (5) body neutrality is unique from positive body image and positivity, (6) body neutrality is a more realistic and inclusive alternative to positive body image and body positivity, (7) body neutrality is different from positive body image but we can still use the research on positive body image to support body neutrality, (8) body neutrality is a midpoint between negative body image and positive body image, (9) striving for body neutrality is sufficient, and (10) appearance can be disregarded. We offer recommendations applicable to researchers, clinicians, media, and the general public interested in body neutrality.

Are diverse models really non-idealized? Investigating body positivity public feed posts of fashion and beauty brands on instagram

Research increasingly explores body positive (BoPo) messaging and diverse model representation in advertising. Fashion and beauty brands are incorporating diverse models in traditional media to address criticisms of promoting narrow appearance ideals, yet their social media communications remain understudied. This content analytical study (n = 460 models, 16 brands) analyzes BoPo messages and diverse model representation in fashion and beauty brands' Instagram posts. Variations according to the brands' reputation, posts' framing, and posts' popularity were considered. Results showed that although diverse models appeared to be prominently featured in the brands' Instagram posts (71.50%; n = 329), the majority of these posts displayed only one aspect of diversity. Racial diversity was the most represented diversity trait (76.29%, n = 251), while body (32.80%, n = 151), facial (12.10%, n = 38), and generational diversity (22.50%, n = 73) were limited. The sexualization frame (88.70%, n = 408) prevailed over the empowerment frame (32.40%, n = 149). Positive changes were noted with the empowerment frame significantly relating to the representation of diverse models. Yet, this study also highlighted that such positive messages still co-occur with negative messages as an empowerment frame co-occurred with a highly prevalent sexualization frame.

The body positive… or the body neutral? A content analysis of body positivity and body neutrality hashtagged videos on TikTok

The goal of the present study was to examine how body positivity and body neutrality are presented on TikTok. Based on a grounded-theory analysis, body-positivity themes included Broadly Conceptualizing Beauty (i.e., diversity in appearance types is beautiful), Body Acceptance and Love (i.e., love for and comfort in one's body), and Critiquing Standards (i.e., rejecting strict appearance standards). Body-neutrality themes included Size Inclusivity (i.e., people's activities/preferences should be based on body size), Adaptive Self-Investment (i.e., self care focused on health), Body Appreciation (i.e., respect for what one's body can do), and No Judgment (i.e., a person's worth should not be based on appearance). Further, based on a content analysis of 394 TikTok vidoes that were hashtagged with body positivity and/or body neutrality terms, at least one body-positivity theme occurred in 35.3% (n = 141) of videos, and at least one body neutrality theme occurred in 45.0% (n = 180) of videos. Body Acceptance and Love was the most common body-positivity theme, and Size Inclusivity was the most common body-neutrality theme. Understanding how TikTok videos present body positivity and neutrality is essential to further theorizing about how they might affect social media users.

Better than average Bopo: Identifying which body positive social media content is most helpful for body image among women

Body positive social media content, and especially content that does not contain photos of bodies, has been shown to be helpful for body image compared to idealized social media content. However, body positive content is heterogenous and little is known regarding which types of content may be most helpful. This study examined self-reported body image and mood effects of different types of body positive content among women. A sample of 176 women, mean (SD) age = 21.77 (2.35) was recruited. Participants viewed body positive stimuli that were grouped into 14 different categories to represent the heterogenous nature of this social media content, including a text only category. Each image was rated in terms of its perceived effect on body image and mood. Findings suggested that the text-only category was rated most highly in terms of generating positive feelings towards the body and positive affect. Moreover, the comparative benefit of the text-only category was larger among women with higher BMI, and participants reporting closer proximity to the images, although not consistently across outcomes. Further work focused on understanding the effects of different types of body positive content is warranted.

Mitigating Harms of Social Media for Adolescent Body Image and Eating Disorders: A Review

Social media has negative effects on adolescent body image and disordered eating behaviors, yet adolescents are unlikely to discontinue engaging with these platforms. Thus, it is important to identify strategies that can reduce the harms of social media on adolescent mental health. This article reviews research on social media and adolescent body image, and discusses strategies to reduce risks associated with social media use. Topics covered include interventions aimed at mitigating social media's negative impacts, the body-positivity movement, and policies regulating adolescents' social media use. Overall, this review highlights specific factors (such as staffing, duration, modality, facilitator training, and cultural sensitivity) to consider when designing and implementing social media interventions targeting adolescents. This review also discusses psychosocial outcomes associated with body positivity on social media. Finally, policy efforts to reduce the negative impact of social media on adolescents' body image and eating behaviors are described. In sum, there is a strong need to conduct further research identifying optimal approaches to reduce the harms of social media for adolescent body image and eating behavior.

Body-Positive Instagram Exposure and Young Women's Body Image: The Mediating Role of Appearance Comparison and Broadly Conceptualizing Beauty

Evidence is mixed as to whether viewing body-positive content on social media can cultivate positive body image in women. Body-positive exposure has been linked to positive (e.g. body satisfaction) and negative (e.g. self-objectification) outcomes. To increase our understanding of the mechanisms underlying the relationship between body-positive social media exposure and positive body image, this study tested two mediators: upward appearance comparisons and broad conceptualization of beauty. Combining insights from social comparison theory, objectification theory, and the acceptance model of body appreciation, we examined whether broadly conceptualizing beauty and engaging in fewer upward appearance comparisons can connect body-positive exposure on Instagram to decreased body surveillance and increased body appreciation. A sample of 345 young women (Mage = 21.65, SD = 1.70) participated in an online survey. Parallel mediation analyses showed that higher relative exposure to body-positive content on Instagram was indirectly related to decreased body surveillance and increased body appreciation, via lower engagement in upward appearance comparisons and a broader conceptualizing beauty. Taken together, body-positive posts on Instagram can positively contribute to women's body image, if they stimulate protective filtering of idealized content, decrease the relevance of idealized models as comparison targets, and increase perceptions of unconditional body appreciation by others.

Two sides of the self-love coin: Self-compassion text-only posts and body positive photo-based content both positively affect body image

Although body-positive content is associated with increased positive body image, concerns regarding the continued focus on appearance have emerged. Therefore, the purpose of this study was to examine whether self-compassion text-only content provided benefits beyond traditional photo-based body positivity content. Undergraduates (n = 283; 179 women, 104 men) were randomly assigned to view body positive photos, self-compassion text-only content, or architectural images (control condition). Participants assigned to both experimental conditions demonstrated a significant increase in measures of state body appreciation, state body satisfaction, and state self-compassion, however they did not differ significantly from each other. The self-compassion condition also differed significantly from the control condition. Trait appearance comparisons moderated the relationship between experimental condition and state body appreciation and state body satisfaction, and gender did not affect the relationship between condition and the outcome measures. Results of this study support the inclusion of body-positivity images and self-compassion text-only content in social media interventions for improving body image for men and women.

Beauty ideals and body positivity: a qualitative investigation of young women's perspectives on social media content in China

Much of the existing knowledge regarding the impact of beauty ideals and body positive social media content on women's body image is based on the Western cultural context. This limits our understanding of the issue in other cultures, such as China, among others. Therefore, to address this gap, this study examined young Chinese women's perspectives on beauty ideals and body positivity in social media through a qualitative investigation. Female university students in China (N = 24) participated in individual interviews. A thematic analysis revealed four primary themes: (1) characteristics of mainstream beauty ideals in Chinese social media; (2) impact of beauty ideals on young women; (3) perspectives on the content and roles of body positivity; (4) influences of body positive social media content on young women. These findings indicate that young Chinese women are aware of the beauty ideals in social media and their negative impact on their body image. Furthermore, young Chinese women generally expressed a favorable outlook on body positivity but noted its limitations.

Physical attributes of workout instructors and appearance-related messaging in a sample of home workout videos on YouTube: A content analysis

Given the popularity of home workouts and effects of exposure to media messaging regarding appearance ideals, the purpose of this analysis was to examine the content of YouTube home workout videos. A sample of 298 YouTube home workout videos was coded for demographic factors and body shape of instructors and the presence of body positivity messaging, appearance-related messaging, and other relevant themes. All videos in the sample included detailed instructions and demonstrations of the exercises by instructors. The majority of the videos depicted young White women with low body fat and thin/athletic bodies with visible muscles. Instructors often focused on burning fat/calories but also emphasized body functionality, exercising for fun/enjoyment, and the importance of taking care of one's body. Overall, findings demonstrate that workout instructors on YouTube conformed to unrealistic, narrowly defined appearance ideals present in Western culture, but the messaging in the videos contained many positive and affirming qualities.

#mybestmidlife: Profiles of photo-based social media use and body image among midlife women

Empirical data, predominantly from young women, suggest photo-based social media use is associated with greater body dissatisfaction. The present study aimed to extend these findings to midlife women and identify risk profiles for maladaptive appearance-focused social media use. A convenience sample of female Instagram users aged 40 or over (M= 50.92 years) (n = 192) was collected. Most participants were partnered, white, highly educated, and heterosexual. A cluster analysis in cross-sectional data grouped participants into four categories according to body image indices (following body positive or fitness accounts, body appreciation and dissatisfaction, thin and muscular ideal internalization, and appearance comparison). Differences by cluster emerged according to indices of social media use (e.g., photo editing, social media rumination), although following appearance-related content across types seemed to distinguish risk profiles more than the types of appearance-related content engaged with (i.e., body positive vs fitness). Furthermore, results indicated that higher social media use was associated with greater perceived negative effects of social media, suggesting that awareness alone may be insufficient to reduce behavioral risk. Findings indicate that some midlife women who use photo-based social media may be at high risk for appearance concerns, warranting further research and resource development for this group.

Mitigating Weight Bias in the Clinical Setting: A New Approach to Care

Weight bias toward patients in larger bodies is pervasive among health care providers and can negatively influence provider-patient communication, as well as patients' behavior and health outcomes. Weight bias has historical roots that perpetuate thinness and Whiteness as the cultural norm. Although weight bias remains socially acceptable in US culture, contributing factors to an individual's body size are complex and multifactorial. Providers and health care systems also consistently use body mass index (BMI) as an indicator of health status, despite its limitations and harmful effects in the clinical setting. This state of the science review presents 8 evidence-based strategies that demonstrate how to mitigate harm from weight bias and improve quality of care and health outcomes for patients living in larger bodies. Person-centered approaches to care include (1) eliminating clinical recommendations to lose weight; (2) shifting from a focus on weight to health; (3) implementing a size and weight-inclusive approach; (4) engaging in weight bias self-evaluation; (5) creating a welcoming environment for patients of all sizes; (6) seeking permission and learning the patient's story; (7) using weight-inclusive language; and (8) re-evaluating clinical guidelines and policies based on BMI. Midwives and other health care providers may benefit from training that re-imagines the delivery of health care to patients in larger bodies.

Does body positivity work for men as it does for women? The impact of idealized body and body positive imagery on body satisfaction, drive for thinness, and drive for muscularity

Exposure to body-positive imagery plays a positive role in women's body image. However, literature has not examined if this is the case for men too. In this study (N = 207), we examined the impact of idealized body and body-positive imagery on both men's and women's body satisfaction and body image concerns. Participants were asked to report their positive and negative mood, body satisfaction, drive for thinness, and drive for muscularity before and after being exposed to either control (landscapes and animals), idealized body, or body-positive imagery. Results showed that women were overall more dissatisfied with their bodies and reported a stronger negative mood and a higher drive for thinness than men. Men, instead, reported a higher drive for muscularity. Exposure to idealized body imagery decreased positive mood and body satisfaction in both men and women. In contrast, exposure to body-positive imagery increased body satisfaction and decreased the drive for thinness in both men and women. Drive for muscularity was not affected by the type of imagery. The findings show that idealized body and body-positive imagery have similar effects on men and women and showcase the importance of considering the effects of body-positivity content for both genders.

#BodyPositive: A qualitative exploration of young people's responses to body positive social media content

Body positive social media content has been suggested to be more helpful to body image as compared to mainstream idealized images. However, body positive content is heterogeneous, and the processes underpinning the effects of body positive social media content on body image are not well understood. The aim of this study was to qualitatively examine variations in reactions to different types of body positive images among young people and their perceptions of the underlying processes. A sample of n=33 people, 67% cisgender women, aged 14-25, mean (SD) = 19.6 (2.57) years, were interviewed. Thematic analysis revealed that body positive content highlighting the unrealistic nature of social media and inclusive in its broad portrayals of beauty were evaluated as most helpful. Two main processes were identified: (1) the broadening of understandings of beauty and greater inclusivity; and (2) the modeling of positive body image and active resistance to appearance ideals. However, these effects may vary according to content creators' characteristics as well as individuals' own body image concerns and their perceived proximity to those portrayed. Additional work across age, gender, and other identities is warranted to identify the most useful types of content for different individuals.

An experimental investigation of whether body-positive messaging on fitspiration and diverse images can improve state body image in women

Viewing body-positive content on social media can benefit women's body image. Previous research has conceptualised body positivity broadly, and therefore it remains unclear whether some components are more useful than others. This study examined the impact of body appreciation or body functionality messages (in addition to a mixed condition) overlaid across different image types to influence women's body image. Young women (17-30 years, Mage= 21.53, N = 308) completed an online survey in which they were randomised to view either fitspiration or diverse images overlaid with messaging focusing on body appreciation, body functionality, or a combination. Participants completed pre- and post-test measures of appearance and functionality satisfaction, body appreciation, and body objectification / conceptualisation. Post-test measures of social comparison and perceptions of models were also taken. Results showed that message type did not interact with image type. Rather, exposure to diverse images increased appearance satisfaction and body appreciation, with no changes to functionality satisfaction (vs a decrease for the fitspiration condition). All conditions improved in self-objectification. Further, diverse images resulted in more favourable social comparisons. Our findings consider body positive content in a controlled way and show no differences across body appreciation or body functionality themes.

TikTok Promotes Diet Culture and Negative Body Image Rhetoric: A Content Analysis

OBJECTIVE

This study aimed to explore the presence of body image and diet culture rhetoric in videos under the hashtag #HealthyLifestyle on TikTok.

METHODS

The top 250 videos under #HealthyLifestyle were categorized using a codebook of wellness topics. We conducted descriptive statistics and interrater reliability analysis.

RESULTS

#HealthyLifestyle videos had high rates of all coded categories, including negative and positive messages about body image and diet culture. Nearly all content with positive connotations was counteracted by coexisting negative messaging.

CONCLUSIONS AND IMPLICATIONS

Our findings suggest that content under #HealthyLifestyle contains messaging conflicting with the definition of a healthy lifestyle. Considering the young audience consuming this content, improved nutrition education and health literacy in schools is essential.

Examining health professional perspectives on social media body image movements: A qualitative exploration

There has been a lack of investigation into the understanding of social media body image movements from the healthcare perspective. Health professionals can have a strong influence on how their patients relate to their own bodies, including experiences of weight-based discrimination. This study examined the perspectives of health professionals on body image social media movements and whether they believed they were relevant to their professional practice. This study recruited 30 medical and allied health professionals to participate in semi-structured interviews. Thematic analysis was used to generate common themes across the data. Overall, participants identified benefits associated with body positivity online content, but expressed concerns for the health status of influencers with larger bodies and that overall, the pro-anorexia movement was harmful. Despite having limited understanding and exposure to the body neutrality movement, participants generally preferred it over body positivity. Finally, participants stated that they believed that these movements were relevant to their practice, yet were rarely discussed in consults. These findings suggest there is a lack of body image-based discussions despite the relevance to patient health across multiple domains. This indicates that health professionals may benefit from social media literacy training to support thorough assessment and treatment of their patients.

Developing a definition of body neutrality and strategies for an intervention

The aim of this study was to provide a definition for body neutrality and understand the key strategies recommended to improve body neutrality for testing in future interventions. There is minimal academic literature on body neutrality and thus this study focused on examining websites where the concept has been discussed for some time. This was achieved using a realist synthesis of websites and a common elements approach to extract the key definition elements of body neutrality, strategies to improve body neutrality, in addition to the common critiques of both the body positivity and body neutrality movements. The initial search found 175 websites, of which 107 were included in the final synthesis, and common elements analysis followed after removal of duplicates and ineligible websites. Three elements, with several sub-elements, best operationalised the definition of body neutrality. Six strategies were found for development of a body neutrality intervention. This innovative study paves the way for rigorous evaluation of body neutrality. Recommendations for future work are provided, including the use of current measures, creating a new measure, and evaluating prevention and intervention programs including Single Session Interventions (SSIs).

The body positivity movement is not all that positive on TikTok: A content analysis of body positive TikTok videos

This analysis examined the content of 342 body positive videos on TikTok. Videos were gathered by searching #body positivity and coded for diversity, positive body image messages, negative appearance-focused messages, other relevant themes, and contradictory messaging. Results demonstrate that body positivity videos on TikTok often portrayed young, White women with unrealistic beauty ideals. Approximately 93% of the videos embodied Western culturally based beauty ideals somewhat or to a great extent, while 32% of the videos portrayed larger bodies. Only 32.2% of the videos contained explicit positive body image messaging, and negative appearance-focused themes or objectifying content was rare. Contradictory messaging was not present. Overall, body positive videos on TikTok rarely displayed features aligned with positive body image and promoted unrealistic beauty ideals but also rarely included explicit negative appearance-focused messaging. Future research examining effects of exposure to body positivity messaging on TikTok, in comparison to other social media platforms, is warranted.

An exploration and comparison of #BodyPositivity and #BodyNeutrality content on TikTok

TikTok, one of the most popular visual social media platforms, has been criticized for perpetuating and glorifying eating disorders. In response, content focused on body positivity (loving your body) is growing on TikTok. However, body positivity content on other social platforms promotes positive body image but also perpetuates unrealistic beauty ideals. Body neutrality (deemphasizing the focus on the body's appearance) is an alternative concept that could portray less harmful content, but has yet to be explored. Therefore, the purpose of this study was to explore and compare the content under #BodyPositivity and #BodyNeutrality on TikTok. One hundred and fifty TikToks under each hashtag were downloaded. A thematic analysis of the TikToks was conducted. Three themes were generated that captured content across both hashtags, with only minor differences in content between the two: (1) Resisting societal ideologies (with subtheme: Normalizing insecurities), (2) (Re)producing disordered content (with subtheme: Toxic (body) positivity promotes the need for neutrality), and (3) Social critique. Within the themes, there was the promotion of body positivity through self-love and body acceptance, but also content that continued to emphasize standard beauty ideals and the thin-ideal. Certain TikToks provided educational content that explained the roots of the #BodyPositivity movement and what #BodyNeutrality means as a potentially more realistic approach to body acceptance. Findings suggest that #BodyNeutrality may provide a safer space for individuals online, and future research should assess the impact of such TikToks on those viewing them to assess body and eating attitudes and behaviours.

Project Body Neutrality: Piloting a digital single-session intervention for adolescent body image and depression

OBJECTIVE

Eating disorders and depression impact youth at alarming rates, yet most adolescents do not access support. Single-session interventions (SSIs) can reach youth in need. This pilot examines the acceptability and utility of a SSI designed to help adolescents improve functionality appreciation (a component of body neutrality) by focusing on valuing one's body based on the functions it performs, regardless of appearance satisfaction.

METHOD

Pre- to post-intervention data were collected, and within-group effect sizes and 95% confidence intervals were computed, to evaluate the immediate effects of the SSI on hopelessness, functionality appreciation, and body dissatisfaction. Patterns of use, demographics, program feedback, and responses from within the SSI were collected.

RESULTS

The SSI and all questionnaires were completed by 75 adolescents (ages: 13-17 years, 74.70% White/Caucasian, 48.00% woman/girl) who reported elevated body image and mood problems. Analyses detected significant pre-post improvements in hopelessness (dav  = 0.60, 95% CI: 0.35-0.84; dz  = 0.77, 95% CI: 0.51-1.02), functionality appreciation (dav  = 0.72, 95% CI: 0.46-0.97; dz  = 0.94, 95% CI: 0.67-1.21), and body dissatisfaction (dav  = 0.61, 95% CI: 0.36-0.86; dz  = 0.76, 95% CI: 0.50-1.02). The SSI was rated as highly acceptable, with a mean overall score of 4.34/5 (SD = 0.54). Qualitative feedback suggested adolescents' endorsement of body neutrality concepts, including functionality appreciation, as personally-relevant, helpful targets for intervention.

DISCUSSION

This evaluation supports the acceptability and preliminary effectiveness of the Project Body Neutrality SSI for adolescents with body image and mood concerns.

PUBLIC SIGNIFICANCE

Results suggest the acceptability and utility of a digital, self-guided, single-session intervention-Project Body Neutrality-for adolescents experiencing co-occurring depressive symptoms and body image disturbances. Given the intervention's low cost and inherent scalability, it may be positioned to provide support to youth with limited access to traditional care.

"Refusing appearance anxiety": A content analysis of body positive posts on Chinese social media

"Body positivity" is a global movement trending on social media. It aims to challenge predominant appearance ideals in media and encourage women to accept and appreciate all bodies regardless of appearance. In Western contexts, an increasing number of research has explored the potential of body positive social media to benefit young women's body image. However, similar research in China is lacking. This study aimed to explore the content of body positivity posts on Chinese social media. Eight hundred eighty-eight posts from Xiaohongshu (one of China's most popular social media platforms) were coded for positive body image themes, physical appearance-related attributes, and self-compassion themes. The results showed that these posts depicted diverse body sizes and appearances. Additionally, while over 40% of the posts conveyed appearance-focused messages, most contained positive body image themes, and nearly half contained self-compassion themes. The study clarified the content of body positivity posts on Chinese social media and provides theoretical support for future research on body positivity in social media content in China.

Realizing the untapped promise of single-session interventions for eating disorders

OBJECTIVE

Multilevel treatment barriers prevent up to 80% of individuals experiencing eating disorders (EDs) from accessing care. This treatment gap creates a critical need to identify interventions that are accessible, easily completable, and optimized for effectiveness by targeting core mechanisms linked to ED onset and maintenance. We propose single-session interventions (SSIs) as a promising path toward catalyzing innovation in the development of accessible, effective ED interventions. SSIs are structured programs that intentionally involve one encounter with a program or provider; they may serve as stand-alone or adjunctive clinical supports. All SSIs are built to acknowledge that any session might be someone's last-and that any single session can nonetheless yield meaningful clinical benefit.

METHOD

We define SSIs, summarize research supporting their utility for ED symptoms and other mental health problems, and recommend future directions for work in this domain.

RESULTS

Single-session interventions may hold promise to reduce some ED symptoms and risk factors, including restrictive eating and negative body image. Steps toward realizing this promise include (1) testing whether existing evidence-based SSIs (e.g., for depression) can also reduce EDs, risk factors, and symptoms; (2) developing novel SSIs that target modifiable ED risk factors and symptoms largely unaddressed by SSIs, such as purging and binge eating; (3) studying diverse implementation pathways; (4) capitalizing on SSIs' transdiagnostic utility to broaden funding opportunities; and (5) educating ED researchers and clinicians about SSIs.

DISCUSSION

Understanding the strengths and limits of mechanism-targeted SSIs for ED-related problems could be a low-risk, high-reward avenue toward reducing EDs at scale.

PUBLIC SIGNIFICANCE

Most individuals experiencing EDs never access any form of treatment, creating an urgent need to identify ED interventions built to overcome barriers to engaging with care. This Forum article introduces SSIs as a promising path to rapidly developing and testing accessible, evidence-based ED supports; supplementing existing ED treatment models; and reducing the individual, familial, and societal burdens of EDs at scale.

Bystanders' Victim Blaming and Minimizing Consequences of Weight-Based Cyberhate Attacks: The Roles of anti-Fat Attitudes, Body-Positive Online Content, and Gender

Physical appearance and, specifically, weight are common reasons for cyberhate attacks among adolescents. Using a between-subject experimental design, this study focuses on the bystanders of such attacks on Instagram. We investigate bystanders' assessments in the form of two moral disengagement (MD) mechanisms-victim blaming and minimizing consequences-and we compare the assessments of attacks that are diversified by the victim's weight (i.e., a victim who is plus-size and a victim who is thinner). We also examine the moderating roles of bystanders' prejudice against people who are plus-size in the form of the so-called anti-fat attitudes, their frequency of viewing body-positive online content, and gender. The study's data come from an online survey conducted in 2020 with a representative sample of 658 Czech adolescents, aged 13-18. We tested our hypotheses with structural equation modeling. The results show that the two MD mechanisms work differently. The victim's displayed weight affected the bystanders' tendency to victim blame: adolescents blamed the victim who is plus-size more than the victim who is thinner, but the victim's weight made no difference in minimizing the consequences of the incident. A moderating effect for anti-fat attitudes and gender was found for victim blaming. Bystanders with higher anti-fat attitudes and boys blamed the victim who is plus-size more than the victim who is thinner. On the other hand, there was no effect for the frequency of viewing body-positive online content for either of the MD mechanisms. The results are discussed with regard to the differences between the two mechanisms and the practical implications for educational and prevention programs for youth.

Body Positivity or Humorous Parody? The Impact of Instagram Imagery on Body Image Concerns

Research has shown that Instagram imagery can affect women's body image. However, it remains unclear how Instagram images are perceived, and which type of images can have a positive impact on body image. In this study (N = 170), we examined whether exposure to body positive and humorous parody (vs. body ideal) imagery would be perceived as critiques of thin body ideals, would elicit photo-based activity in the form of "likes", and would positively affect women's body image. Results showed that both body positivity and humorous parody images elicited more "likes" and were perceived as critiquing thin body standards more than body ideal images. Moreover, women's body satisfaction and positive mood were higher after exposure to body positivity and humorous parody compared to exposure to body ideal images. Women exposed to humorous parody also reported a lower drive for thinness. These findings demonstrate that both body positivity and humorous parody can be considered critiques that improve body image.

The impact of social media use on body image and disordered eating behaviors: Content matters more than duration of exposure

Social media use is rapidly expanding in terms of frequency, duration, and the diversity of platforms available. Given evidence for associations between social media use, body image disturbances, and disordered eating it is important to identify potentially harmful aspects of social media use that could serve as intervention targets. This study surveyed two demographically diverse undergraduate student cohorts in 2015 and 2022 to compare patterns in social media use, body image, and disordered eating behaviors between samples, including as a function of the COVID-19 pandemic, and to test the hypothesized moderating role of specific content consumed in the association between social media use and maladaptive outcomes. Participants in 2022 reported greater body image disturbances, more frequent vomiting and laxative use, and more time spent on a greater number of social media accounts, with significantly greater use of image-based platforms such as Snapchat, TikTok, and YouTube. Moderated regression analyses suggest that type of content consumed, but not the amount of time spent on social media or diversity of platforms utilized, is associated with body image disturbances and disordered eating behaviors after controlling for gender and body mass index. Specifically, exposure to weight loss content was associated with lower body appreciation, greater fears of negative appearance evaluation, and more frequent binge eating. Contrary to initial hypotheses, exposure to body positivity/neutrality content did not have protective effects. Findings suggest that interventions targeting negative consequences of social media use should focus on addressing content consumed, rather than time spent on social media platforms.

Can following body positive or appearance neutral Facebook pages improve young women's body image and mood? Testing novel social media micro-interventions

Small changes to social media use could have a large impact across the population. The present study tested novel social media micro-interventions (i.e., brief content delivered in everyday life) in which young women (N = 159) were instructed to either (1) follow a body positive Facebook group, (2) follow an appearance neutral Facebook group, or (3) use Facebook as usual. Relevant content was posted to the Facebook groups three times per day for two weeks. Primary outcomes were trait body image (body dissatisfaction and appreciation) and mood, and secondary outcomes were trait self-objectification, appearance comparison tendency, and body activism. Outcomes were assessed across three timepoints: pre-test (T1), post-test (T2) after the 14-day intervention period, and follow-up (T3) 4-weeks after T2. Participants in both the body positive and appearance neutral conditions reported decreased body dissatisfaction from T1 to T2 (small-medium effects) and participants in the body positive condition reported decreased appearance comparisons from T1 to T2 (medium effect). There were no changes for those variables from T2 to T3. No other significant differences were found. Viewing a small number of body positive or appearance neutral posts on social media may be an effective inexpensive micro-intervention for improving young women's body image.

Obesity Stigma: Causes, Consequences, and Potential Solutions

PURPOSE OF REVIEW

This review aims to examine (i) the aetiology of obesity; (ii) how and why a perception of personal responsibility for obesity so dominantly frames this condition and how this mindset leads to stigma; (iii) the consequences of obesity stigma for people living with obesity, and for the public support for interventions to prevent and manage this condition; and (iv) potential strategies to diminish our focus on personal responsibility for the development of obesity, to enable a reduction of obesity stigma, and to move towards effective interventions to prevent and manage obesity within the population.

RECENT FINDINGS

We summarise literature which shows that obesity stems from a complex interplay of genetic and environment factors most of which are outside an individual's control. Despite this, evidence of obesity stigmatisation remains abundant throughout areas of media, entertainment, social media and the internet, advertising, news outlets, and the political and public health landscape. This has damaging consequences including psychological, physical, and socioeconomic harm. Obesity stigma does not prevent obesity. A combined, concerted, and sustained effort from multiple stakeholders and key decision-makers within society is required to dispel myths around personal responsibility for body weight, and to foster more empathy for people living in larger bodies. This also sets the scene for more effective policies and interventions, targeting the social and environmental drivers of health, to ultimately improve population health.

Effects of COVID-19 specific body positive and diet culture related social media content on body image and mood among young women

During the COVID-19 pandemic, social media content emerged that included explicit weight and shape pressure. In addition, however, body positive social media content that was pandemic-specific appeared. This study aimed to examine the effects of body positive and diet culture COVID-19 body-related social media content on the body image and mood of young women. A sample of 387 female identifying participants aged 18-25 were allocated to view one of three sets of social media images: body positive or diet related content specific to the COVID-19 pandemic, or a travel condition. Body image and mood before and after viewing the images were assessed. Trait level social media literacy and current social distancing and isolation restrictions were examined as moderators. Exposure to the body positive content was associated with improved body image and mood as compared to the diet culture content. No support was found for moderating effects although social media literacy was associated with improved body image after exposure. Findings suggest that even in the context of the COVID-19 pandemic, body positive content may be helpful to body image. Further work examining inter-individual differences in the effects of social media on body image and mood are warranted.

TikTok, TikTok, the time is now: Future directions in social media and body image

This article synthesizes practical strategies and future directions proposed by contributors to the special issue in Body Image on social media and body image. It also moves beyond the contributions of the special issue in an effort to provide additional guidance to researchers, clinicians, educators, and policymakers. First, we recommend that research on social media and body image extend beyond convenience sampling of young, White women and include children and older adults, boys and men, and underrepresented groups. Second, we urge researchers to move away from simplistic measures of social media and to utilize mixed-methods approaches. Third, we advocate for the development of new theories that can be tested longitudinally and that capture the unique influences of social media, rather than relying solely on existing models that were developed for traditional media. Fourth, we provide recommendations regarding practical strategies, such as the inclusion of media literacy campaigns, increased research on the role of reality check disclaimers, and further examination regarding the role of body positivity in prevention and intervention efforts. Finally, we end with recommendations regarding advocacy, such as using social media to harness positive efforts and partnering with social media companies regarding their use of algorithms.

Imagery versus captions: The effect of body positive Instagram content on young women's mood and body image

Body positive social media content aims to positively impact young women's body image and mood by challenging traditionally narrow beauty ideals. This online experiment investigated the effect of viewing body positive Instagram posts on young women's body image and mood, whilst focusing on understanding the impact of the images and captions in the posts. Overall, 195 young women (18-30 years old) were randomly assigned to view either body positive (consisting of images and captions), body positive captions only, body positive images only, or thin-ideal Instagram posts. Positive mood increased in all conditions pre to post exposure. Further, body satisfaction and negative mood improved pre-post exposure for all body positive conditions. However, when controlling for trait body appreciation significant effects only remained for the combined image and caption body positive condition. There were no significant differences in positive mood, state body appreciation, self-objectification, or broad conceptualisations of beauty between the three body positive exposure conditions. Therefore, to improve body satisfaction and mood, body positive content should include a combination of images and captions.

Integrating social media variables as predictors, mediators, and moderators within body image frameworks: Potential mechanisms of action to consider in future research

In this article, we consider how social media variables may be integrated as predictors, mediators, and moderators within dominant theoretical frameworks of body image in order to identify potential mechanisms of action that can be empirically examined in future research and used to direct prevention and intervention efforts. To achieve this goal, we first articulate social media variables that have been investigated as predictors, mediators, and moderators in body image research. Next, we present the following critical and sociocultural theoretical frameworks: social comparison theory, tripartite influence model, objectification theory, developmental theory of embodiment, acceptance model of intuitive eating, cultivation theory, and uses and gratifications theory. Additionally, we present the theory of development of critical body awareness, a newly developed model that may provide further insight regarding the relationships between social media and body image-related outcomes. For each model, we articulate extant research that has explored social media variables within its context and explicate how social media variables could potentially be studied as predictors, mediators, and moderators within its structure. To conclude, we address pertinent limitations and gaps within this research space that could direct future research across the theoretical frameworks.

#SexyBodyPositive: When Sexualization Does Not Undermine Young Women's Body Image

Research suggests that exposure to social networking sites portraying a thin and often sexualized beauty ideal reduces young women's body satisfaction, while exposure to body-positive content improves it. However, it is unclear whether sexualization could impair the beneficial effects of body-positivity messages. Young Italian women were exposed to one of three experimental conditions showing sexualized beauty ideals, sexualized body positivity, or non-sexualized body positivity that appeared either on Instagram (Study 1, N = 356) or TikTok (Study 2, N = 316). Across the two studies, results showed that, regardless of sexualization, exposure to body positivity increased body satisfaction and positive mood compared with pre-exposure measures, while exposure to sexualized beauty ideals reduced it. Participants in the sexualized beauty ideal condition also engaged in upward appearance social comparison whereas body positivity elicited downward comparison. Problematic social networking sites' use moderated the effects of condition on body satisfaction, appearance social comparison, and positive mood, while downward comparison mediated the relation between condition and body satisfaction and positive mood. Our results highlight both beneficial and critical aspects of body positivity that should be taken into consideration when designing body image interventions and policymaking.

I'm Skinny, I'm Worth More: Fashion Models' Experiences of Aesthetic Labor and Its Impact on Body Image and Eating Behaviors

The fashion industry has been critiqued for promoting ultra-thin bodies, yet the relationship between models' aesthetic labor and eating disorder (ED) development is unclear. Using interpretive phenomenological analysis, we explored the lived experiences of nine female fashion models including metaphors they used to describe body perceptions and eating behaviors. Four superordinate themes emerged: Shaped for the industry; The body as a market product; Food restriction ("it's almost glamorized"); Toward a healthier modelhood. Models' career trajectories were those of lost childhoods, punitive body rules, inadequate dietary advice, and self-regulated food restriction. Models were "shaped" by agents from an early age to conform to the industry's body rules irrespective of the physiological and psychological consequences. A "toxic" side to this aesthetic industry was depicted; agents were judged callous and money-focused, while idioms like, "feeling like a piece of meat" and "being a hanger of clothes" conveyed a deep sense of degradation and objectification. Ideas instilled at a formative age continued to influence self-image and eating patterns into maturity, pointing to an industrial element to the construction of eating disorders. Our study highlights how infantilization, sexism, and other unethical elements become normalized in poorly regulated industries such as fashion, with dire consequences for the health and wellbeing of employees. Model agencies should recognize the impact of occupational edicts and poor communication on young recruits in a sensitive phase of personality development. Finally, we advocate for more acknowledgment and further investigation into eating disorder construction commercial/industrial side.

“Why don’t I look like her?” How adolescent girls view social media and its connection to body image

Background

Adolescent girls appear more vulnerable to experiencing mental health difficulties from social media use than boys. The presence of sexualized images online is thought to contribute, through increasing body dissatisfaction among adolescent girls. Sexual objectification through images may reinforce to adolescent girls that their value is based on their appearance. This study explored how sexualized images typically found on social media might influence adolescent girls’ mental health, in positive and/or negative ways.

Methods

In-depth interviews were conducted with girls aged 14–17 years (n = 24) in Perth, Western Australia. Data were analyzed using thematic analysis.

Results

Participants identified body image as a major concern, reporting negative appearance comparisons when viewing images on social media. Appearance comparisons were perceived to exacerbate adolescent girls’ appearance-based concerns. Comparisons also influenced adolescent girls’ efforts to change their appearance and seek validation on social media. The importance of awareness and education from a younger age about social media and its influence on body image was emphasized, as was the need for strategies to promote positive body image and counteract negative body image.

Conclusion

The findings of this study have important implications for professionals working with adolescent girls and for the development of health promotion programs addressing social media use and body image concerns.

The Perfect Storm: A Developmental-Sociocultural Framework for the Role of Social Media in Adolescent Girls' Body Image Concerns and Mental Health

In this theoretical review paper, we provide a developmental-sociocultural framework for the role of social media (SM) in adolescent girls' body image concerns, and in turn, depressive symptoms and disordered eating. We propose that the features of SM (e.g., idealized images of peers, quantifiable feedback) intersect with adolescent developmental factors (e.g., salience of peer relationships) and sociocultural gender socialization processes (e.g., societal over-emphasis on girls' and women's physical appearance) to create the "perfect storm" for exacerbating girls' body image concerns. We argue that, ultimately, body image concerns may be a key mechanism underlying associations between adolescent girls' SM use and mental health. In the context of proposing this framework, we provide empirical evidence for how SM may increase adolescent girls' body image concerns through heightening their focus on (1) other people's physical appearance (e.g., through exposure to idealized images of peers, celebrities, and SM influencers; quantifiable indicators of approval); and (2) their own appearance (e.g., through appearance-related SM consciousness; exposure to idealized self-images; encouraging over-valuing of appearance; and peer approval of photos/videos). Our framework highlights new avenues for future research on adolescent girls' SM use and mental health, which recognize the central role of body image.

#BodyPositive? A critical exploration of the body positive movement within physical cultures taking an intersectionality approach

Feminist activists and critical sport scholars in the global north have advocated for more inclusive representation of bodies and more accessible physical cultures. Body positivity, a contentious movement and concept, has been taken up in various ways by different groups. Some scholars believe it holds power to liberate individuals from patriarchal, neoliberal, capitalist, and colonial ideologies of what constitutes a "good" body. On the contrary, critics assert this movement has been gentrified by white-centered politics. Intersectionality has a similar genealogy as body positivity, with a rich history in Black feminist thought but now considered by many as coopted and whitened. In this article, we trace the rich and divergent legacies of both movements and explore at the structural level how body positivity is represented within physical cultures on Instagram. We use a social-justice oriented intersectionality framework exploring #BodyPositivity and #BodyPositive across a total of 141 posts using reflexive thematic analysis. We organize our findings into four themes: 1) Disclosure-Privilege of Body-Related Journeys; 2) The Absent-Present; 3) Consuming Positivity; and 4) Disrupting Normative Body Positivity Posts. Overall, we found that only certain bodies (and transformations) were visible within the data: those of (now) lean, white, cis-gendered individuals, many of whom were engaged in bodybuilding, and who were sharing their bodily transformation. We observe a remarkable absence of BIPOC, 2S LGBTQAI+, fat/thick/thicc/curvy, older, gender-nonconforming, and/or disabled representations. We also note the myriad ways that body positivity has been commodified and packaged into a product or service for consumption. Lastly, we outline and celebrate the exceptions to this norm where a minority of posts align more closely with the original intentions of the body positivity movement. We conclude with our position on how to do intersectionality research, and call on researchers to honor Black feminist origins and rich social justice history in these movements.

Promoting body positivity through stories: How protagonist body size and esteem influence readers' self-concepts

Through two experiments (N = 497), we documented how distinct portrayals of women in stories can impact readers' engagement in social comparisons and influence important aspects of their self-concepts. Specifically, this research investigated the effects of character body size (thin vs. large), body esteem (low vs. high), and story ending valence (sad vs. happy) with two distinct storylines. Results indicated that high (vs. low) body esteem characters are not only rated more aspirational, but also led readers with greater self-discrepancy to report lower state body image, suggesting upward social comparison processes are at play. Further, results indicated that reading about characters with large (vs. thin) bodies can positively affect readers' body image; however, this positive effect may be explained by downward social comparison. Findings highlight the complexities of body appearance and confidence. Strategies for effectively promoting body positivity via text-based interventions are discussed.

The effects of body-positive Instagram posts on body image in adult women

While recent studies have examined the effects of viewing body-positive social media content on body appreciation and satisfaction in young adult women, research has yet to include older adult women. The current study assessed the effects of viewing body-positive Instagram content on body image in 205 adult women (18-76 years old) who were randomly assigned to view either body-positive, thin-ideal, or appearance-neutral Instagram content. Our findings demonstrated that exposure to body-positive Instagram content resulted in greater levels of body appreciation and body satisfaction compared to exposure to thin-ideal and neutral Instagram content, while no significant differences were found between any of the conditions on self-objectification. Finally, age was only a significant moderator for one variable (self objectification) and condition (thin ideal), indicating that exposure to body-positive social media content may improve levels of body appreciation and satisfaction in adult women, regardless of age.

#Body goals or #Bopo? Exposure to pregnancy and post-partum related social media images: Effects on the body image and mood of women in the peri-pregnancy period

Women who are pregnant or have recently given birth use social media where they may encounter content promoting appearance ideals or offering more realistic representations of the body during this unique period. To date, little is known regarding the ways in which different social media content may impact the body image and mood of women who are pregnant or postpartum. A sample of 261 participants aged 21-44, mean (SD) age = 31.79 (4.402), were randomly allocated online to view either thin-and-toned ideal or body positive social media content specific to the pregnancy and postpartum period, or a neutral travel condition. Findings revealed that exposure to the body positive images had positive effects on body image relative to the thin-and-toned ideal condition, as well as leading to increases in some indices of positive body image, while the thin-ideal images were harmful. Partial support emerged for the protective roles of body appreciation and low social media-related rumination among women exposed to the thin-and-toned ideal images. Social media content may be harmful or helpful to the body image and mood of pregnant and postpartum women, which is important given the documented relationships between maternal body image, mood, and maternal and infant outcomes.

A moderated mediation model for body-positive online content and body image among adolescents

Body-positive online content (BPOC) has recently become widespread, yet the factors that explain its association with body satisfaction have scarcely been studied. The current study investigates the indirect association between the self-reported frequency of viewing BPOC and body satisfaction through body appreciation and the moderating roles of body-ideal internalization, self-esteem, intentional searching, and gender. Utilizing survey data from 1530 Czech adolescents aged 13-18 (M=15.4, SD=1.7, 50 % girls), the present study found limited support for an indirect connection between the frequency of viewing BPOC and body satisfaction through body appreciation. Nonetheless, an indirect association appeared among adolescents with average and above-average frequencies for intentional searching for BPOC. Other investigated moderating factors were not significant. The present findings suggest that BPOC may be positively associated with body image, but only for those who deliberately search for it. The study highlights the importance of individual moderating factors in the context of BPOC and the remaining research gaps, such as the examination of its various types and aspects and their relationship with body image.

#BeautyInspo: Unraveling the Relationships Between Nonidealized Content on Different Media Platforms, Inspiration, and a Broad Conceptualization of Beauty

The current literature on nonidealized media content (i.e., content that presents media models that do not follow traditional beauty standards) rarely includes novel positive body image outcomes, such as a broad conceptualization of beauty. Moreover, little is known about more positively oriented explanatory mechanisms, such as inspiration (i.e., feeling inspired by media to adopt a broader inner conception of beauty). Therefore, the current cross-sectional survey study among 458 women aged 19-30 years old (M = 22.76, SD = 2.64) investigated the links between exposure to nonidealized content on different media platforms, inspiration, and a broad conceptualization of beauty. Conditional process analysis, using Hayes' PROCESS tool, was performed. Our results indicated that exposure to nonidealized content through Instagram posts of influencers/celebrities as well as magazine articles was positively linked to women's broader conceptualization of beauty. Inspiration was also found to be a significant mediator in these relationships. Moreover, inspiration was found to fully mediate the relationship between exposure to nonidealized content through companies' Instagram posts and a broad conceptualization of beauty. No relationships were found for exposure to nonidealized content through television series or movies. These results highlight how nonidealized media models can optimally empower media users, as well as how some media platforms might have a greater potential to fulfill this empowering role than others. The findings inform practitioners of the relevance of including nonidealized media content in intervention programs.

Public health in the making: Dietary innovators and their on-the-job sociology

Diet is understood to be one of the most important influences on public health and chronic disease, and is particularly implicated in the so-called 'obesity epidemic'. Yet interventions aiming to improve the population's dietary habits have failed to translate into widespread health improvements. Simultaneously, the knowledge landscape has become increasingly contentious, with fat activism challenging dominant approaches to how obesity is framed and addressed. This paper is based on 24 ethnographic interviews, and explores the work of health practitioners promoting therapeutic carbohydrate restriction ('low-carb' diets) for people with metabolic health conditions. Drawing on Michel Callon's study of technological innovation, I show practitioners engaging in 'on-the-job sociology'-situated sociological work to justify, and forge a space for, innovative dietary intervention. These innovators employ physiological explanations of hormones, satiety (or hunger), and pleasure (or shame), supported with personal experience, to emphasise material connections between particular eating habits and the sustainability of dietary improvement in everyday life. They resist fat activist influence on healthcare practice (that has resulted in practitioners avoiding conversations about diet, fatness and health), as well as the more extensively critiqued practices of health promotion. Deflecting blame/shame from individuals, innovators spotlight the role of the food industry in undermining public understandings of food and physiology, and dietary improvement that is achievable and sustainable. Through on-the-job sociology, innovators forge a space to engage patients in collaborative dietary experimentation and improvement. This study highlights the importance of on-the-job sociology in the contemporary knowledge landscape, providing new insights about public health in the making.

Social media and body image: Modulating effects of social identities and user characteristics

Social media use and exposure, in particular to highly visual and appearance-focused content, has shown a relationship with poorer body image with small to moderate effect sizes. The aim here was to provide an overview of the theoretical and empirical evidence of the relationships between social media use and body image may vary across individuals. Although evidence exists to support variations in these relationships across different groups, to date, data are scarce and a number of theoretically important groups have largely been overlooked. The available evidence suggests that age may be an important moderating factor of vulnerability to exposure to highly-visual social media content, with younger adolescents most likely to experience negative outcomes. In addition, women and other groups for whom appearance is strongly tied to attractiveness and self-worth may be at heightened risk. Moving forward further research should aim to focus on understanding the relationships between social media use and body image concerns among underrepresented groups, and to expand the focus of to include different aspects of social media use and more sophisticated methodological approaches.

The dangers of the rabbit hole: Reflections on social media as a portal into a distorted world of edited bodies and eating disorder risk and the role of algorithms

The relationship between social media usage and body image has been well-established in the literature; however, social media companies' use of algorithms may intensify this association, as algorithms provide viewers with personalized content that is often more extreme, less monitored, and designed to keep users engaged for longer periods of time. This article details the recent media coverage of algorithms, revelations by former social media employees regarding the problematic usage of algorithms, and revelations that social media companies are aware of the harm posed by their implementation of algorithms, particularly for young, vulnerable users. We provide recommendations for influencers, educators, researchers, clinicians, parents, and users, and conclude that it is ultimately the responsibility of the social media corporations to protect and enhance the well-being of their users.
