Diagnosis of PCOS is established when at least two of the following are present: hyperandrogenism, oligo-anovulation, and\/or polycystic ovaries. Conservative treatment for PCOS includes dietary modifications and physical activity. The purpose of this scoping review was to evaluate the efficacy of a ketogenic diet in improving biochemical measures and reducing the severity of PCOS symptoms. Methods: CINAHL, PubMed, and Google Scholar databases were searched to find research published in peer-reviewed journals between 2019 and 2025. An article was included in this scoping review if the study assessed the effectiveness of a ketogenic diet on improving the signs and symptoms in patients with PCOS. Results: Eight studies met the inclusion criteria. Weight loss was achieved by subjects who adopted a very low-calorie ketogenic diet (VLCKD), low-calorie ketogenic diet (LCKD), classic ketogenic diet (CKD), or a Mediterranean eucaloric ketogenic diet (KEMEPHY). Patients with PCOS who consumed a ketogenic diet experienced improved biochemical measures, including androgen levels, lipid levels, HOMA-IR, blood glucose, insulin, LH\/FSH ratio, DHEAS, SHBG, AFC, and AMH. A ketogenic diet was also associated with improvements in menstruation, fertility, and OHSS. Conclusions: Adopting a short-term ketogenic diet may have positive health benefits for patients with PCOS.<\/jats:p>","DOI":"10.3390\/nu17172893","type":"journal-article","created":{"date-parts":[[2025,9,8]],"date-time":"2025-09-08T10:29:07Z","timestamp":1757327347000},"page":"2893","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Polycystic Ovary Syndrome and the Effects of a Ketogenic Diet: A Scoping Review"],"prefix":"10.3390","volume":"17","author":[{"given":"Dayelise","family":"Fleigle","sequence":"first","affiliation":[{"name":"Doctor of Medical Science Program, College of Medical Science, George Fox University, Newberg, OR 97132, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7662-3453","authenticated-orcid":false,"given":"Jason","family":"Brumitt","sequence":"additional","affiliation":[{"name":"Doctor of Physical Therapy Program, College of Allied Health, George Fox University, Newberg, OR 97132, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Erika","family":"McCarthy","sequence":"additional","affiliation":[{"name":"Doctor of Medical Science Program, College of Medical Science, George Fox University, Newberg, OR 97132, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Travis","family":"Adelman","sequence":"additional","affiliation":[{"name":"Doctor of Medical Science Program, College of Medical Science, George Fox University, Newberg, OR 97132, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Corey","family":"Asbell","sequence":"additional","affiliation":[{"name":"Doctor of Medical Science Program, College of Medical Science, George Fox University, Newberg, OR 97132, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Singh, S., Pal, N., Shubham, S., Sarma, D.K., Verma, V., Marotta, F., and Kumar, M.
