There is a site and free self published e-book of about 60 pages (hard copy is available too) on an IF diet in which one fasts for all but 5 hours a day for the purpose of weight loss. The book describes the author as a retired medical doctor and former researcher in the Metabolism branch of the National Cancer Institute. Cancer is not discussed in the book although there is a brief section on physiology and the three mechanisms throught to underlie the effect. See http://www.fast-5.org/ http://www.fast-5.org/
