Hi, as always, regarding health conditions, especially cancer, you should consult your doctor. What I am stating here is not a recommendation, just my experience as a doctor and scientific research that I am linking below. Intermittent fasting (IF) can enhance insulin sensitivity, lower blood sugar levels, and decrease inflammation markers (mostly studies in rats) . However, the claim that IF can remove cancer cells is bold and should not be seen without traditional treatments like chemo or radiochemotherapy. Emerging evidence suggests that fasting could play a key role in cancer treatment by fostering conditions that limit cancer cells’ adaptability, survival, and growth. Fasting could increase the effectiveness of cancer treatments and limit adverse events. Yet, we lack an integrated mechanistic model for how these two complicated systems interact, limiting our ability to understand, prevent, and treat cancer using fasting.
