(8, 9) or they have only been used in a handful of studies yet Factors such as cultural, demographic, or social differences may have a significant impact on the results, which requires further research on more diverse groups. In addition, most studies were conducted on specific populations, which limits the possibility of generalizing the results to wider groups. It is worth noting that the studies discussed provide a lot of valuable information that can be helpful in diagnosing ON. Mass media often promote unrealistic body patterns, which can lead to comparisons and dissatisfaction with one’s own appearance. Social media, such as Instagram and Facebook, are seen as tools that can shape attitudes and behaviors related to nutrition not only in adolescents but also in adults. The results showed a high incidence of ON symptoms, reaching 76% among all participants .Given the widespread dissemination of health and wellness trends through digital media and the internet, orthorexia nervosa will likely transcend geographical boundaries. Moreover, understanding the global prevalence of orthorexia nervosa is crucial to address its impact on public health. Individuals can embark on a healing journey by developing greater self-awareness and self-compassion, gradually overcoming the grip of orthorexia nervosa and cultivating a healthier and more fulfilling life . Mindfulness and acceptance-based treatments are emerging as promising therapeutic approaches for individuals with orthorexia nervosa . Intuitive eating helps individuals overcome rigid dietary rules and adopt a more mindful and non-judgmental approach to eating, promoting self-compassion and body acceptance . Nutritional counseling and intuitive eating approaches are valuable components in the comprehensive treatment of orthorexia nervosa.Despite orthorexia not being "technically" classified as an eating disorder, it can often lead to one of the above eating disorders. Orthorexia nervosa and healthy orthorexia as new eating styles. Individuals with an eating disorder often deny the severity of their illness, and the term healthy orthorexia makes it too easy for this denial to continue. The blurred lines between nonpathological healthy eating and ON are blurred even further by the term "healthy" orthorexia.3,5,13,14 People with ON have similar personality traits as people with anorexia nervosa (AN), an eating disorder of restrictive eating, fear of weight gain, and extreme weight loss.1,2,3 These personality similarities include perfectionism, anxiety, and obsessive-compulsive behaviors. This review paper comprehensively examines orthorexia and orthorexia nervosa, encompassing prevalence, risk factors, diagnosis, and treatment strategies.Moralization stigmatizes some foods, contributing to eating disorders such as orthorexia. Unlike other eating disorders, orthorexia mostly revolves around food quality, not quantity. Orthorexia nervosa is an eating disorder that involves a fixation on healthy eating. (In both terms, "nervosa" indicates an unhealthy psychological state.) Bratman described orthorexia as an unhealthy fixation with what the individual considers to be healthy eating. One study found that there was no relationship between BOT score and college major, which may indicate the prevalence of mental health issues and eating disorders on college campuses and that health and science majors are no longer the only ones affected. A diagnostic questionnaire has been developed for orthorexia sufferers, similar to questionnaires for other eating disorders, named the ORTO-15. However, studies of other eating disorders such as anorexia nervosa, bulimia nervosa, and binge eating disorder have noticed several biological influences.Subsequently, the term "orthorexia nervosa" emerged to describe a more severe variant characterized by intense anxiety, distress, and functional impairments related to the rigid pursuit of an idealized and "pure" diet . However, discussions around clean eating also come with debates about the potential for creating rigid eating patterns, promoting unrealistic body standards, and contributing to the stigmatization of certain foods . Disordered eating behaviors have emerged as a critical public health concern, drawing increasing attention from researchers, healthcare professionals, and policymakers.Talking with a qualified health professional, such as a doctor, psychologist, or registered dietitian, is strongly recommended. Therefore, being underweight is not a diagnostic factor, and weight restoration won’t be part of everyone’s recovery journey. However, the effectiveness of these treatments for orthorexia hasn’t been scientifically confirmed.Over-valued ideas are not always distressing, and so do not negatively reinforce behaviors that help avoid, counteract, or neutralize them 39, 40. Preliminary studies have shown strong internal consistency of the EHQ, suggesting reliability . Based on a systematic review of existing reviews, it is clear that current instruments such as the widely used ORTO-15 are, at best, mediocre screening tools for ON, and there have been several disagreements on the conceptualization and hence diagnostic criteria of ON. However, the absence of a link with dysregulated eating indicates that ON’s restrictive eating might not be as severe or calorie-focused as in other EDs, thereby differentiating ON from other EDs . Apart from the methodological shortcomings, ON’s diagnostic conundrum also implicates conceptual issues. The inconsistency in prevalence rates is attributed to the varied diagnostic tools used, and a contemporary re-conceptualization of ON is required to advance the field . The ORTO-15 also omits obsessive-compulsive behaviors that might confound the results obtained .e.g., the Eating Habits Questionnaire (10) or the Orthorexia Nervosa Inventory (11); cf. However, studies have shown consistently that this instrument has poor psychometric properties, the most prominent of which is its low internal reliability e.g., (7–9). The large majority of studies on ON have been based on a questionnaire measure called the ORTO−15 (3) or several short versions of it e.g., (4–6). Additionally, studies suggest that the risk of ON may be particularly high in groups practicing yoga, where a greater tendency to orthorexic behavior is observed . The first one is whether OC (obsessive–compulsive symptoms) should be considered a behavioral phenomenon or lifestyle, or rather a mental disorder. The current lack of unified diagnostic and therapeutic guidelines limits the possibilities of effective intervention, which emphasizes the need for further research on the treatment of orthorexia. First coined by Bratman and Knight in 1997, the term orthorexia nervosa describes individuals with an obsession for proper nutrition who pursue this obsession through a restrictive diet, a focus on food preparation, and ritualized patterns of eating. Are motives for food choices different in orthorexia nervosa and healthy orthorexia? In contrast, individuals who scored high on ON behaviors reported more negative affect toward their eating and lifestyle habits compared with individuals who scored high on reported healthy orthorexia behaviors. Like ON, healthy orthorexia isn't clearly defined.3,5,13,14 Broadly, people with healthy orthorexia are thought to have an interest in, but not an obsession with, healthy eating and maintaining a healthy lifestyle. Cross-cultural studies can explore how cultural norms, beliefs, and societal pressures influence attitudes toward food, body image, and health, potentially shedding light on unique risk factors and protective factors specific to different cultural contexts. The historical context surrounding these disorders highlights the complex interplay between societal norms, technological advancements, and the human desire for health and wellness, emphasizing further research and understanding to address the emerging challenges of orthorexia and orthorexia nervosa. Nevertheless, further research is warranted to better understand the prevalence, underlying risk factors, and effective treatment strategies for these emerging eating disorders. However, the proposed diagnostic tools and questionnaires aid in identifying individuals with disordered eating habits related to food purity and health obsessions. Venn diagram showing unique and overlapping features of orthorexia nervosa, anorexia nervosa, and obsessive–compulsive disorder (OCD). Many of the features described above echo symptoms of anorexia nervosa and obsessive–compulsive disorder (OCD), conditions that are themselves highly comorbid and have functionally similar clinical presentations,9 prompting debate as to whether orthorexia is a unique disorder or a subset of anorexia or OCD (Figure 1). The opinions and views of our guest contributors are shared to provide a broad perspective of eating disorders. This is why educating coaches about eating disorders and disordered eating is so important. Sometimes the signs of disordered eating are hard to notice because they are often normalized as "healthy" eating. Data concerning the former are mixed, with some studies suggesting a low degree of association between OCPD and OCD15,16 and others indicating significant and specific associations.17,18 Concerning the latter relationship, there is some evidence that OCPD, rather than OCD, has a close link with eating disorders,19 particularly to anorexia.20 Other research has shown that the presence of OCPD traits positively predicts development of pathological eating habits.21,22 An examination of diagnostic boundaries reveals important points of symptom overlap between orthorexia and anorexia nervosa, obsessive–compulsive disorder (OCD), obsessive–compulsive personality disorder (OCPD), somatic symptom disorder, illness anxiety disorder, and psychotic spectrum disorders. Orthorexia nervosa describes a pathological obsession with proper nutrition that is characterized by a restrictive diet, ritualized patterns of eating, and rigid avoidance of foods believed to be unhealthy or impure. Answer some general questions about your eating habits, how you feel about food, and your, your thoughts on "healthy" eating, and other indicators of orthorexia. After analyzing the obtained results, the authors noted associations between ON and eating disorders occurring with exercise addiction . In young adults, a correlation between the occurrence of eating disorders and ON can also be observed . The results suggest that users who actively follow accounts related to healthy eating may be more prone to obsession with healthy eating. In today’s digital world, eating habits are largely shaped by social media, which promotes specific diets and lifestyles that can further amplify orthorexia symptoms. When reviewing the literature on orthorexia nervosa (ONER), it can be seen that many studies focus on the role of gender as a significant factor influencing orthodox tendencies. These attitudes may be reinforced by social media, which promote global patterns of beauty and healthy lifestyles, influencing eating habits. In the study by Karniej et al. conducted in Poland and Spain, unique predictors of psychological orthorexia nervosa (ON) were identified among homosexual men. As a finite and depletable set of resources, WM operations can be easily disrupted by attention to task-irrelevant stimuli, whether internal or external;56 it is possible, for example, that ongoing preoccupation with food- and health-related images or thoughts weakens WM in orthorexia,34 as similar findings have been reported in the eating disorders literature. In orthorexia, individuals adopt eating habits given a desire to be healthy, natural, or pure,1,12 entertaining unrealistic, if not magical, beliefs about certain foods.13 Anorexic individuals tend to hide their behaviors, whereas orthorexic individuals are more likely to flaunt their habits.1 With regard to OCD, the most significant difference is that the content of obsessions in orthorexia is perceived as ego-syntonic, rather than ego-dystonic.8 In a recent study by Barthels et al. (2019), individuals who scored high on healthy orthorexia behaviors reported more positive affect toward their eating and lifestyle habits compared with individuals who scored high on self-reported ON behaviors.
