Oh, and forgot to address the second point. I've read all of the Dr's blog posts. He promotes coffee, tea and water during fasting as long as they don't include sugar or sweeteners. I think he says if you really have to have something, then you can use a small amount of cream, but then you aren't really fasting. I think that's what he says, but since I don't drink coffee or put anything in my tea, I didn't pay attention to those parts.

For probably the past 6-8 months, I've been trying to do all of my eating during an 8 hour period (not always successfully). For about 1-2 months I've kicked it up a notch, and I've been fasting about 2 days a week. Usually 2x for 24-36 hours, but a couple weeks I've done 48-60 hours (one long fast). I feel fine before, during and after the fasts. I started running again about 3-4 months ago. I have run on days that I've fasted and even on my second day fasting for 30-60 mins, up to 6.5 miles. I'm not setting any records, but like I said, I only recently took it up again. What I can tell you is that I'm not really seeing any difference if I exercise while fasting, at least, not any more than I normally see day to day fasting or not.
