This is a good news article by David Liu on the Food Consumer website. It relates to how fasting can have significant anti-cancer benefits and is protective of the brain. Latter the article references Professor Mattson, who long ago wrote a fascinating little article entitled, "Starve me and watch my brain run". He is now investigating the possibility of intermittent fasting as an anti-dementia strategy. After reading his previous work and that of others I long ago decided that intermittent fasting is one of the best things we can do for our health in general and cancer and cognitive function in particular. This is good epidemiological, physiological, and cellular data to support this contention. Three levels of analysis confirmation is good enough, especially given the strength of the primary data.
If you are at all serious about maintaining good health you must think very seriously about fasting as an integral part of your lifestyle. For another example of that have a look at the previous post on the news report, Short fasting cycles work as well as chemotherapy in mice. In relation to the other benefits of fasting you'll have to read on.
