I looked briefly into this and it seems that while there is evidence that intermittent fasting may be useful in preventing cancer and may be useful as an adjunct cancer treatment (in addition to chemotherapy and/or other treatments), the effect is largely from weight loss, not other mechanisms. Review article here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9530862/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9530862/ From the conclusion: "There is presently little evidence that intermittent fasting, without any reduction in body weight and proper balanced diet and exercise, can enhance cancer outcomes." So, while the details in this review are interesting, the conclusions seem to come down to basic health advice: maintain a healthy weight, eat a healthy diet, and get exercise. Seems like good advice for pretty much everyone.
