In an article by Roger Collier, published in the Canadian Medical Association Journal, on intermittent fasting,  Collier reminds us that “benefits are exaggerated.  Risks are downplayed.  Science takes a backseat to marketers.”  Roger also states that intermittent fasting is quickly becoming a fab.  This, of course, doesn’t mean that intermittent fasting is bad.  However, intermittent fasting will become subjected to lots of marketing.  Thus making the benefits exaggerated and the risks downplayed.  For example, marketers will often promote intermittent fasting as a way to fast for a certain amount of time a week and then have a “cheat” day consisting of the consumption of whatever you want.  While still reaping the benefits of the fast.  This theory/method is possible.  However, the limits and standards of a “cheat” day are never addressed.  Often people end up over-eating and acquiring all of the calories and/or fat that they abstained from during their fast.

Eventually, Roger Collier acknowledges that there is a “large body of research to support the health benefits of fasting.  Though most of it has been conducted on animals, not humans.  Still the results have been promising.  Fasting has shown to improve biomarkers of disease, reduce oxidative stress and preserve learning and memory functioning, according to Mark Mattson, a senior investigator for the National Institute on Aging, part of the U.S. National Institutes of Health.”
