Fasting for Brain Health

“Intermittent fasting enhances the ability of nerve cells to repair DNA.” 

He also goes into the evolutionary aspect of this theory – how our ancestors adapted and were built for going long periods of time without food.


A study published in the June 5 issue of Cell Stem Cell by researchers from the University of Southern California showed that cycles of prolonged fasting protect against immune system damage and, moreover, induce immune system regeneration. They concluded that fasting shifts stem cells from a dormant state to a state of self-renewal. It triggers stem cell based regeneration of an organ or system. (source)

Human clinical trials were conducted using patients who were receiving chemotherapy. For long periods of time, patients did not eat, which significantly lowered their white blood cell counts. In mice, fasting cycles “flipped a regenerative switch, changing the signalling pathways for hematopoietic stem cells, which are responsible for the generation of blood and immune systems.”

This means that fasting kills off old and damaged immune cells, and when the body rebounds it uses stem cells to create brand new, completely healthy cells.

“We could not predict that prolonged fasting would have such a remarkable effect in promoting stem cell-based regeneration of the heatopoietic system. . . . When you starve, the system tries to save energy, and one of the things it can do to save energy is to recycle a lot of the immune cells that are not needed, especially those that may be damaged.  What we started noticing in both our human work and animal work is that the white blood cell count goes down with prolonged fasting. Then when you re-feed, the blood cells come back. ” – Valter Longo, corresponding author (source)

A scientific review of multiple scientific studies regarding fasting was published in The American Journal of Clinical Nutrition in 2007. It examined a multitude of both human and animal studies and determined that fasting is an effective way to reduce the risk of cardiovascular disease and cancer. It also showed significant potential in treating diabetes. (source)

Before You Fast

Before you fast, make sure you do your research. Personally, I’ve been fasting for years, so it is something that comes easy for me.

One recommended way of doing it — which was tested by the BBC’s Michael Mosley in order to reverse his diabetes, high cholesterol, and other problems that were associated with his obesity — is what is known as the “5:2 Diet.” On the 5:2 plan, you cut your food down to one-fourth of your normal daily calories on fasting days (about 600 calories for men and about 500 for women), while consuming plenty of water and tea. On the other five days of the week, you can eat normally.

Another way to do it, as mentioned above, is to restrict your food intake between the hours of 11am and 7pm daily, while not eating during the hours outside of that time.

Bottom line, how you think about you’re diet is, in my opinion, one of the most, if not the most important part of staying healthy. How you think about what you are putting in your body is important, and I believe this will eventually be firmly established in the untainted, unbiased, uninfluenced medical literature of the future.

Below is a video of Dr. Joseph Mercola explaining the benefits of intermittent fasting. Here is a great article by him that explains how he believes intermittent fasting can help you live a healthier life.
