On the other hand, little is known about diets that prevent colonic carcinogenesis. The ketogenic diet, which is characterized by high fat and very low carbohydrate content, is one such diet. The ketogenic diet decreases the amount of available glucose for tumors and shifts to the production of ketone bodies as an alternative energy source for healthy cells. Cancer cells are unable to use the ketone bodies for energy thus depriving them of the energy needed for progression and survival. Many studies reported the beneficial effects of the ketogenic diet in several types of cancers. Recently, the ketone body \u03b2-hydroxybutyrate has been found to possess anti-tumor potential in colorectal cancer. Despite its beneficial effects, the ketogenic diet also has some drawbacks, some of which are related to gastrointestinal disorders and weight loss. Thus, studies are being directed at this time towards finding alternatives to following a strict ketogenic diet and supplementing patients with the ketone bodies responsible for its beneficial effects in the hope of overcoming some potential setbacks. This article discusses the mechanism by which a ketogenic diet influences growth and proliferation of tumor cells, it sheds the light on the most recent trials regarding its use as an adjunctive measure to chemotherapy in patients with metastatic colorectal cancer, and it explains the limitations of its usage in metastatic patients and the promising role of exogenous ketone supplementation in this setting.<\/jats:p>","DOI":"10.3390\/ijms24043683","type":"journal-article","created":{"date-parts":[[2023,2,13]],"date-time":"2023-02-13T03:28:46Z","timestamp":1676258926000},"page":"3683","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["The Ketogenic Diet in Colorectal Cancer: A Means to an End"],"prefix":"10.3390","volume":"24","author":[{"given":"Magie","family":"Tamraz","sequence":"first","affiliation":[{"name":"Department of Nutrition and Dietetics, American University of Beirut Medical Center, Riad El Solh, Beirut 1107, Lebanon"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Najib","family":"Al Ghossaini","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Ain Wazein Medical Village, Chouf 5841, Lebanon"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sally","family":"Temraz","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, American University of Beirut Medical Center, Riad El Solh, Beirut 1107, Lebanon"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"209","DOI":"10.3322\/caac.21660","article-title":"Global Cancer Statistics 2020: GLOBOCAN Estimates of Incidence and Mortality Worldwide for 36 Cancers in 185 Countries","volume":"71","author":"Sung","year":"2021","journal-title":"CA Cancer J.
