Its all good man. Yeah I was fortunate enough to meet Robb at one of his nutrition certs 2 years ago. Since then the man has been nothing short of a life saver for me. Based on the zone calculator I'm at 19 blocks. I will roll with that for at least 3 weeks and see how things go.
In regards to that article, it mentions that some sort of activity during the fast will help things out. Now would this be the same as doing 20 minutes of "cardio" after waking up from a 12 hour fast?
