Great post! Sounds like you're off to a wonderful start. As 3rdday mentioned, Dr. Fuhrman's diet plan (Eat to Live) is among the best. I would definitely recommend his approach, not only with eating, but with his water-fasting perspective, as contained in his '95 book.
Today, actually, is the start of my own fourth day of fasting. So, I'm just a few days behind you. While I'm close to your age, fifty-one, I'm a little skinnier. Once 205, I've managed to drop 40 lbs over the past few years. Hasn't been easy, but here I am. In fact, my concern with this fast is with losing too MUCH weight.
