: A healthy diet is essential for managing Polycystic Ovary Syndrome (PCOS), yet optimal recommendations remain unclear, highlighting the need to explore alternative lifestyle interventions. The Mediterranean diet (MedDiet) supports cardiometabolic health; however, challenges with adherence within this population are unknown. This study examines the acceptability and experiences of an ad libitum MedDiet in women with PCOS, offering recommendations for implementation. : A 12-week MedDiet intervention was conducted with women aged 18-45 years, diagnosed with PCOS and a BMI ≥ 25 kg/m ( = 12). Adherence was assessed using the Mediterranean Diet Adherence Screener. Surveys and semi-structured interviews, guided by the Capability, Opportunity, Motivation-Behaviour (COM-B) model, explored participants' experiences. Thematic analysis identified barriers and facilitators, which were mapped to the COM-B and Theoretical Domains Framework (TDF), with all findings subsequently aligned with the Behaviour Change Wheel to inform implementation strategies. : MedDiet adherence significantly improved from baseline to week 12 (Baseline: 4.1 ± 1.8; week 12: 8.3 ± 2.3; = 0.001), alongside increases in knowledge ( = 0.004), cooking confidence ( = 0.01), and time management ( = 0.01). Adherence factors were mapped to 12 of the 14 TDF domains. Key facilitators included health benefits, reduced weight pressure, educational resources, and simple guidelines. Barriers involved organisation, food availability, and external influences. Effective implementation should integrate MedDiet education, behaviour change support, practical resources, and professional training for nutrition professionals and healthcare providers to support referrals and weight-neutral dietary management. : A short-term ad libitum MedDiet is acceptable for women with PCOS. Strategies for patients and healthcare providers, aligned with the intervention functions of education, training, and enablement, are key to supporting adherence.
健康饮食对于多囊卵巢综合征（PCOS）的管理至关重要，但最佳建议仍不明确，这凸显了探索其他生活方式干预措施的必要性。地中海饮食（MedDiet）有助于心脏代谢健康；然而，该人群对其依从性方面的挑战尚不清楚。本研究探讨了PCOS女性对自由选择的地中海饮食的可接受性和体验，并提出了实施建议。对18 - 45岁、被诊断为PCOS且体重指数（BMI）≥25 kg/m²（n = 12）的女性进行了为期12周的地中海饮食干预。使用地中海饮食依从性筛查工具评估依从性。以能力、机会、动机 - 行为（COM - B）模型为指导，通过调查和半结构化访谈探索参与者的体验。主题分析确定了障碍和促进因素，并将其映射到COM - B模型和理论领域框架（TDF），所有结果随后与行为改变轮相结合，以指导实施策略。从基线到第12周，地中海饮食的依从性显著提高（基线：4.1±1.8；第12周：8.3±2.3；P = 0.001），同时知识（P = 0.004）、烹饪信心（P = 从基线到第12周，地中海饮食的依从性显著提高（基线：4.1±1.8；第12周：8.3±2.3；P = 0.001），同时知识（P = 0.004）、烹饪信心（P = 0.01）和时间管理（P = 0.01）也有所增加。依从性因素被映射到TDF的14个领域中的12个。关键促进因素包括健康益处、减轻体重压力、教育资源和简单指南。障碍包括组织、食物供应和外部影响。有效的实施应整合地中海饮食教育、行为改变支持、实用资源，以及为营养专业人员和医疗保健提供者提供专业培训，以支持转诊和体重中性饮食管理。短期自由选择的地中海饮食对PCOS女性是可接受的。与教育、培训和赋能等干预功能相一致的针对患者和医疗保健提供者的策略，是支持依从性的关键。 01）也有所增加。依从性因素被映射到TDF的14个领域中的12个。关键促进因素包括健康益处、减轻体重压力、教育资源和简单指南。障碍包括组织、食物供应和外部影响。有效的实施应整合地中海饮食教育、行为改变支持、实用资源，以及为营养专业人员和医疗保健提供者提供专业培训，以支持转诊和体重中性饮食管理。短期自由选择的地中海饮食对PCOS女性是可接受的。与教育、培训和赋能等干预功能相一致的针对患者和医疗保健提供者的策略，是支持依从性的关键。
