I have been doing Intermittent fasting for a while using Brad Pilon's Eat Stop Eat guidelines. I have always enjoyed the IF and felt good during the fasting period.
I just started my Primal Blueprint lifestyle change a couple weeks ago. I did the slow progression into it and have felt really good.
Today (starting at 7PM last night) was my first IF since starting the Primal change. All I can say is WOW! I have NEVER felt this good during a fast. There has always been moments of "hunger" during my IF in the past but not today. I haven't wanted anything all day. Plain green tea and water are the only two things I have ingested since 7PM last night and I haven't even thought of food or hunger since.
I am not sure if it can be attributed to the Primal Blueprint nutrition but this truly is the first time I have felt completely at ease during a fast.
Feel free to share your thoughts on this or challenge yourself to do a fast once you are settled into the primal nutrition lifestyle!
