Peter, Our experience with hair analysis over the past 17 years indicates that 80% of the population has high tissue calcium. Our assumption is that when Os eat right 4 their type they will start dumping or eliminating that excess calcium. This says to us that it will probably be quite some time before an O with high tissue calcium would need to worry about calcium supplemnts. That excess calcium swimming in the blood stream is now available if the body should happen to need it. Our experience says that removed calcium has a tendency to temporarily slow everything down leading to fatigue, depression, constipation, etc. Does your experience bear this out? I think your experince with Os with Chronic Fatigue with Potassium suppliments (to counter the Ca) and licorice would help substantiate this idea. Also, while on Atkins I was always in ketosis. Now with some fruit and Ez. bread in my diet that's not always true. Should I use ketosis as a guide to how much fruit and Ezekiel bread to eat while I'm trying to lose weight? Thanks so much for your time. Sincerely, Alice
