This review aimed to synthesize evidence from systematic reviews and meta-analyses on the effects of ketogenic diets in cancer, focusing on metabolic outcomes, body composition, quality of life, and tumor progression. Treatment-related complications were considered as exploratory outcomes.  \nMethods: A comprehensive review of meta-analyses were conducted following PRISMA guidelines. Databases including PubMed, Scopus, and Web of Science were searched for systematic reviews and meta-analyses exploring the effects of KDon cancer and treatment side effects. After screening 615 articles, 24 eligible reviews were examined to explore the effects of ketogenic diets on metabolism, quality of life, body composition, and cancer progression.  \nResults: KD improved metabolic markers such as glucose and triglycerides, and showed benefits in body composition and quality of life. Evidence on treatment-related complications, including radiotherapy side effects, was limited and heterogeneous.  \nConclusions: KD shows promise as a safe and effective adjunctive therapy in cancer management. More evidence is needed to draw firm conclusions.  \nKeywords  \nketogenic diet, cancer, side effect, radiotherapy  \nReceived: February 3, 2025; accepted: January 26, 2026  \nIntroduction  \nCancer is the second leading cause of death from non-communicable diseases in the world. Globally, more than 20 million new cancer cases were diagnosed in 2022, and over 9.7 million people died from the disease. Despite this burden, access to treatment has expanded substantially, with millions of patients now receiving chemotherapy, radiotherapy, surgery, or targeted therapies; However, notable differences in care continue across regions.1 This continuing rise  \nin incidence and mortality highlights the urgent need for coordinated global strategies to reduce the cancer burden and to ensure equitable access to effective treatments across populations.2  \nStandard cancer treatments such as chemotherapy, radiotherapy, and surgery remain the cornerstone of care worldwide.3 However, these modalities are frequently associated with adverse effects including fatigue, nausea, gastrointestinal disturbances, and treatment-induced malnutrition, which can strongly affect patients’ quality of life (QoL) and limit  \nCreative Commons Non Commercial CC BY-NC: This article is distributed under the terms of the Creative Commons AttributionNonCommercial 4.0 License ([https://creativecommons.org/licenses/by-nc/4.0/](https://creativecommons.org/licenses/by-nc/4.0/)) which permits non-commercial use, reproduction and distribution of the work without further permission provided the original work is attributed as specified on the SAGE and Open Access pages ([https://us.sagepub.com/en-us/nam/open-access-at-sage](https://us.sagepub.com/en-us/nam/open-access-at-sage)).  \nadherence to therapy.4 Optimal nutritional support plays ","cbCaifje4MIK9iuI","https://ap.wps.com/l/cbCaifje4MIK9iuI","pdf",639312,"English","# Abstract\n## Background\n## Methods\n## Results\n## Conclusions\n# Introduction\n# Methods\n## Study Selection and Search Strategy","[{\"question\":\"What is the purpose of the review?\",\"answer\":\"To synthesize evidence from systematic reviews and meta-analyses on how ketogenic diets affect cancer outcomes, including metabolic indices, body composition, quality of life, and tumor progression.\"},{\"question\":\"Which outcomes were emphasized in the included evidence?\",\"answer\":\"Metabolic markers (e.g., glucose and triglycerides), body composition, and quality of life were central, while treatment-related complications such as radiotherapy side effects were considered as exploratory outcomes.\"},{\"question\":\"What did the results suggest about ketogenic diets in cancer care?\",\"answer\":\"The evidence indicated improvements in metabolic markers and potential benefits for body composition and quality of life, but findings on treatment-related complications were limited and heterogeneous.\"}]","The Effect of a Ketogenic Diet on Cancer - Evidence From Systematic Reviews and Meta-Analyzes | PDF",1790116915,23]
