The mystery is intriguing and leads me to wonder what the differences are between your original pre-zone diet and Paleothin. Surely the answer must be there. "Protein Power" by Eades describes a patient (p.88) who lost weight and lowered cholesterol on their low-carb program but stubbornly maintained high blood pressure. They had him substitute fish and chicken for steak and mostly egg whites for whole eggs and his hypertension normalized. Eades blamed dietary AA for producing bad eicosanoids. Your experience tempts me to have blood tests done now (in my 2nd month in the Zone) so I can compare with later results. Alas, I'm presently without health insurance & I suspect these tests must be not inexpensive. Kathryn
