Yes, I read those things too. I have wondered if the slower your reintroduce food the less likely you are to regain weight. One thing I read suggested reintroducing food in a certain order over half the time you fasted. So if you fasted for 60 days, you took 30 days to reintroduce food. This would take a lot of discipline but I do wonder as I said, that it might lessen the amount of regained weight, somehow I think it would. It seems to me based on my own experience and that of others that the minute you start eating your body rejoices in the sudden calorie intake and puts it all in storage lol. However, an interesting thing I have also observed with myself and other juicers is that when you come off a prolonged fast you are kinda stumped for what to eat. You don't crave food like you did. Your taste buds have completely changed. For me juicing felt like a safety net too, a comfort zone.
I am considering taking longer when I come off this current fast and see what happens. Its really not about being able to eat, because 5 days is plenty for you to be able to handle food again without feeling ill. Its about rebalancing my body in such a way that it doesn't get excited about the food and store it. I have a condition called PCOS, which is like metabolic syndrome so it is my bodies natural thing to just store store store.....anyway, I'm just thinking out loud here and hope I haven't confused you again.
