A more scientific study on the benefits of fasting leading to improved cell regeneration was posted on HN a few days ago. Here's the corresponding journal paper http://dx.doi.org/10.1016/j.stem.2014.04.014 (paywalled)
I'm just too used to seeing extraordinary dietary benefits being promoted for all sorts of fad foods/diets like blueberries, grapefruit, atkins diet, paleo diet, etc... So I felt like pointing out that there was very little in the way of experimental evidence in that paper (I'm from a physics background, love my data).
With any luck this won't be another one of those papers that gets perverted in the press to "Fasting cures cancer!"
