Fasting is not only a common diet strategy for weight loss but is also being researched as a potential way to combat cancer. Studies have shown that fasting can boost the immune system’s natural killer cells, which can fight cancer cells without prior exposure. A study conducted at Memorial Sloan Kettering Cancer Center found that fasting reprograms natural killer cells to better survive in the hostile environment of tumors, making them more effective at fighting cancer. The study revealed that fasting alters the metabolism of natural killer cells and boosts the production of important proteins necessary for fighting tumors. Overall, fasting shows potential in enhancing immune responses and could be used to improve immunotherapy strategies.
