A consensus or society position rather than new primary data.
This is a narrative review of nutrition-based approaches to cancer management that examines dietary modulations (ketogenic, fasting-mimicking, macronutrient manipulation), cancer prevention through diet, and supportive nutritional strategies across treatment stages. The authors conclude that early studies and preclinical research show promise but acknowledge that the exact impact on cancer therapy outcomes remains unclear and requires well-designed, large-scale clinical trials.
Narrative review. Cancer patients receiving modern therapies (chemotherapy, immunotherapy, radiation, hormone therapy, oncolytic viruses, CAR-T); individuals at risk of or with established cancer.
Dietary modulations including ketogenic diets, fasting-mimicking diets and macronutrient changes have shown promise in early studies and preclinical research Current cancer therapies commonly cause serious side effects such as cachexia and treatment-related anorexia that reduce quality of life and treatment tolerance Dietary factors including processed foods and alcohol increase cancer risk, while plant-based diets and certain micronutrients may help prevent cancer
Current cancer therapies commonly cause serious side effects such as cachexia and treatment-related anorexia that reduce quality of life and treatment tolerance
This review suggests that clinicians should consider tailored nutritional assessment and support as an adjunctive strategy to reduce treatment side effects (cachexia, anorexia, mucositis) and potentially enhance treatment tolerance. However, adoption of specific dietary interventions like ketogenic or fasting-mimicking diets should await evidence from large-scale randomized controlled trials, as efficacy on hard cancer outcomes remains unproven.
A narrative review synthesizing evidence on nutrition-based approaches to cancer management; provides expert perspective on dietary interventions and supportive strategies but explicitly identifies the need for large-scale trials to establish clinical efficacy.

Graded across the dimensions that decide whether you should act, each from what the source actually supports. There is no single score, and where a dimension was not assessed it says so.
What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
Modern cancer therapies include chemotherapy, immunotherapy, radiation therapy, hormone therapy and newer methods like oncolytic viruses and chimeric antigen receptor T-cell therapy.These therapies are commonly used to manage cancer, but many patients face serious side effects such as cachexia and treatment related anorexia which can lead to a lower quality of life and a reduced ability to tolerate treatment.This review explores nutrition-based approaches that might help reduce these side effects and improve the effectiveness of these therapies.Dietary modulations like ketogenic diets, fasting mimicking diets and changes in macronutrient intake have shown promise in early studies and preclinical research.These approaches may interact with how tumors use energy and help patients better handle their treatment.However, the exact impact of these strategies on cancer therapy outcomes remains unclear and needs more research through well designed, large scale clinical trials.The review also examines dietary factors that could lower the risk of developing cancer, and it looks at how processed foods and alcohol increase cancer risk as well as how plant-based diets and certain micronutrients may help prevent cancer.These factors might reduce cancer risk by lowering oxidative stress, reducing chronic inflammation, altering gut bacteria and changing gene expression.Additionally, strategies tailored to specific stages of cancer treatment including assessing and optimizing nutritional needs pre-treatment providing supportive nutrition during treatment for conditions like mucositis and malnutrition and managing recovery has also been discussed.New experimental technologies such as nanoparticles like cargos, CRISPR-Cas9 and artificial intelligence as a key part of comprehensive cancer care are the key points which has been discussed with the goal of improving treatment results and enhancing the quality of life for cancer survivors.
