Sorry, I think I misunderstood the part about "in the beginning". So, we're talking about something like Atkins induction, but instead of 20g/carbs/day/2 weeks it's just zero for 2 weeks, right? Well then it's real simple, find solid evidence for the Atkins diet especially the induction phase, use that to support the advice to do zero-carb for induction instead. Thing is 20g is much closer to zero than 300g. Ima say use the A-TO-Z experiment where they compared the Atkins, Zone, Ornish, and some other diet.

I'm not sure how to fit this idea of reshaping one's biochemical pathways, but it's a start though. Add the one you posted, add others you find, at some point you'll figure out some way to make that idea fit.
