Final inclusion required a histologically confirmed diagnosis of ulcerative colitis (UC) or Crohn\u2019s disease that was responsive to treatment with a ketogenic or carnivore diet without medication or with successful medication cessation on the diet. Clinical improvement was measured with the Inflammatory Bowel Disease Questionnaire (IBDQ).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>We report on 10 cases of IBD responsive to ketogenic, mostly carnivore, diets. Clinical presentations were diverse, including six cases of UC and four of Crohn\u2019s disease. Clinical improvements were universal, with clinical improvement scores ranging between 72 and 165 points on the IBDQ. Patients\u2019 diets comprised mostly meat, eggs, and animal fats. Patients report their diets are pleasurable, sustainable, and unequivocally enhance their quality of life.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Ketogenic and carnivore diets hold promise for the treatment of IBD, including UC and Crohn\u2019s disease. These cases are consistent with clinical literature that shows an inverse association between intestinal ketone levels and IBD activity, as well as the therapeutic effects of low residue elimination diets on colonic microbiota metabolism.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fnut.2024.1467475","type":"journal-article","created":{"date-parts":[[2024,9,2]],"date-time":"2024-09-02T04:28:30Z","timestamp":1725251310000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":36,"title":["Case
