Fasting—or the practice of regularly abstaining from ingesting anything except water—is a pretty drastic move. I tried to fast for two days and made it to the 12-hour mark, which is when I broke down and ate a quart of ice cream.

However, I may have to try it again, since “short-term starvation” (as scientists like to call it) might have potentially wonderful effects on one’s health, from rebooting the immune system to helping chemotherapy work more effectively for cancer patients.

Not Eating Gives Your Body a Chance to Rebuild Itself
The Telegraph UK spoke with Dr. Longo, who said that fasting encourages the human body to produce more white blood cells, which are the key to a healthy, functioning immune system.

About fasting, Longo stated, “It gives the ‘OK’ for stem cells to go ahead and begin proliferating and rebuild the entire system. The body got rid of the parts of the system that might be damaged or old, the inefficient parts, during fasting. Now, if you start with a system heavily damaged by chemotherapy or aging, fasting cycles can generate, literally, a new immune system.”
