There is a blog at http://www.medichecks.com/index.cfm?s=5&d=6 about a brother and sister who are both trying the 5:2 diet. What makes it interesting is that they are directors of MediChecks, which does IGF-1 testing, so they are helpfully using themselves as guinea pigs and intend to publish the results on their blog, including changes in their IGF-1 levels. And they both start off with generally good health and weight. First related blog entry was on 30th November.

P.S. Just for the record I have no connection with MediChecks and this is not a commercial!
