Background: Adolescents with obesity participate in self-directed weight loss attempts, and these may be associated with disordered eating. This study aimed to understand prior engagement with a dietitian and previous dieting practices of adolescents presenting for obesity treatment. Additionally, we aimed to understand the association between prior dieting and eating disorder risk, binge eating, weight bias internalisation and body image. Methods: This cross-sectional study included 141 adolescents (median IQR age: 14.8 13.8–15.7 years) with BMI 35.28 (31.99–38.57) kg/m2 and ≥1 related complication presenting for a prescriptive dietary intervention. Adolescents were asked whether they had previously seen a dietitian (yes/no) and/or previously trialled any other diets for weight management. Associations between reported diets and the Eating Disorder Examination Questionnaire (EDE-Q), the Binge Eating Scale, the Weight Bias Internalisation scale and Body Appreciation Scale scores were assessed using multiple one-way ANOVAs. Results: A total of 68 (48.2%) adolescents had previously seen a dietitian and 106 (75.2%) had trialled at least one diet. Most adolescents had used one diet type (n = 74; 52.5%), and 29 (20.6%) had used two or three different diets. Most adolescents reported following a healthy eating pattern (n = 76; 53.9%), with 11 trying a low-carbohydrate diet (7.8%) or a specific eating plan, e.g., low sugar, vegetarian (n = 11; 7.8%). There were no associations between dieting attempts and scores of measures of disordered eating, weight bias or body appreciation. Conclusions: Many adolescents presenting for obesity treatment will have trialled diets, with or without the support of a dietitian. Clinicians providing nutrition education and prescribing dietary interventions should be aware of this and the potential influence on adolescent perceptions of dieting practices.
