I have just managed to get hold of a copy of Jason Fung's fasting book - so hopefully, more info is on hand.
One of the things I had heard from a cancer doctor - was when fasting for cancer - water only, and then distilled water at that. Having been eating ketogenically for a while - fasting is not a hard thing to do!

Polycythemia vera:
I am a journalist who was on a big story, and uranium, silicate glass, and antimony were found in one burner of my gas stove. 9 months after exposure after I started passing silicate glass kidney stones. Uranium was also found in my hair and the urine of one member of our family. Less than 2 years later, my platelet count was super low, and hemoglobin creeping up. Iron also was elevated 6 years later. Am now dealing with a diagnosis of polycythemia vera.
My understanding is that it's often attributed to genetic mutations due to radiation exposure and is not usually hereditary. Also, ATSDR study in PA where there were increased incidents of polycythemia vera showed an increase in exposure to coal dust with uranium in it. Just thought I'd comment about my experiences. If you smell a rat in your personal situation, there may be one. Two known criminals went to jail in relation to my case.
Wishing all of you the best outcomes.
Eating the Right Foods Cured Polycythemia Vera Bonnie (Florida, US) on 11/07/2014

I was diagnosed with Polycythemia Vera in 2010. My red blood cells were at 1 million and normal is 200,000 to 400,000. My cancer doctor started giving me phlebotomys and hydroxyurea. The lowest my red cell count ever got to was 800,000. Two years ago I looked up foods that thin your blood and started eating them. I was visiting my dad at the time and went to his doctor after two weeks being on this diet. He did a blood test and my count was 300,000!!! He asked if I was sure about being diagnosed with PV and I told him I had a bone marrow biopsy and was positive. He couldn't believe it.
If you want, just look up foods on the internet that thin your blood and avoid the ones that thicken your blood. I no longer take hydroxyurea or get phlebotomys and am normal!!
