I just purchased the Bulletproof Diet book and I'm very new to it. I just started three days ago with the Bulletproof coffee. At 6:30am I'm drinking eight ounces of coffee with two tablespoons of 100% grass fed organic ghee and gradually one tablespoon of Brain Octane. I'm also doing intermittent fasting and not eating until 2:00 pm. My question is how long can I continue Bulletproof coffee with intermittent fasting? Is there a period that one should stop doing both for awhile? Thanks in advance!
