I have been following the NSD for about 17 months. My cholesterol went up about 60 after 3 months on the diet. After 6 months, it went back to its original level. I think it takes some time for your body to adapt to the diet. I am still trying to find what works for me. My LDL levels also increased and then dropped back. They are still slightly elevated from my original starting point.
Not sure about my WBC. I stopped Humira 8 month ago though. I spaced the shots out immediately after starting diet. (3 wks to 6 wks to 10 wks).
