In 2016, formal criteria for<unk>  were proposed in the peer-reviewed journal Eating Behaviors by Thom Dunn and Steven Bratman. These criteria are as follows: Criterion A. Obsessive focus on "healthy" eating, as defined by a dietary theory or set of beliefs whose specific details may vary; marked by exaggerated emotional distress in relationship to food choices perceived as unhealthy; weight loss may ensue, but this is conceptualized as an aspect of ideal health rather than as the primary goal. As evidenced by the following: #Compulsive behavior and/or mental preoccupation regarding affirmative and restrictive dietary practices believed by the individual to promote optimum health. (Footnotes to this criteria add: Dietary practices may include use of concentrated "food supplements." Exercise performance and/or fit body image may be regarded as an aspect or indicator of health.) #Violation of self-imposed dietary rules causes exaggerated fear of disease, sense of personal impurity and/or negative physical sensations, accompanied by anxiety and shame. #Dietary restrictions escalate over time, and may come to include elimination of entire food groups and involve progressively more frequent and/or severe "cleanses" (partial fasts) regarded as purifying or detoxifying. This escalation commonly leads to weight loss, but the desire to lose weight is absent, hidden or subordinated to ideation about healthy food. Criterion B. The compulsive behavior and mental preoccupation becomes clinically impairing by any of the following: #Malnutrition, severe weight loss or other medical complications from restricted diet #Intrapersonal distress or impairment of social, academic or vocational functioning secondary to beliefs or behaviors about healthy diet #Positive body image, self-worth, identity and/or satisfaction excessively dependent on compliance with self-defined "healthy" eating behavior. A diagnostic questionnaire has been developed for<unk>  sufferers, similar to questionnaires for other eating disorders, named the ORTO-15. However, Dunn and Bratman critique this survey tool as lacking appropriate internal and external validation.
