Weekly update / report:
Weight: Lost another 1.5 pounds - making it 7 pounds in total over the last two weeks
Blood pressure: Still very good
Blood glucose: About the same as last week.
I don't think this can be a constant way of eating for me and I admire anyone who eats this way all the time. It is not easy, very boring and the 'bathroom issues' are not nice.

(Yes, I know, TMI.)
I am missing veg more each day and the food boredom is increasing. ZC is achieving what I wanted it to do with my BG but it did most of that in the first week and reduced my blood pressure (not sure why but I'm happy about it). I have noticed I've been getting headaches quite often which is something I'm not used to suffering with - I don't know if its connected.
I think, for me, I will use ZC in the same way people use fasting as it has pretty much the same results for me as fasting used to but without the rumbling tummy.
So, after giving it a lot of thought, after this weekend, I will transition on to ZC on Tuesdays, Wednesdays, Thursdays and back to very low carb for Fridays to Mondays. If I notice my BG going up I will revert to ZC all the time as it is an excellent tool for reducing BG.
