A quick reply to your post. I too, have had problems, particularly with my trigycerides. They were in excess of 700 about a year ago (and had been for years). After being put on fenofibrate for about 6 months my level went down to high 300s. My family has a real problem with high triglycerides and sugar addiction. I had blood tests only 6 weeks apart. The first was done within a week of my starting the paleo diet and walking. My triglycerides were 375 and my cholesterol was 197. Only six weeks of 100% compliance on the paleo diet, my triglycerides were only 89 and my cholesterol was 119. These values represent the first time in decades that my blood lipids have been in very healthy range. I am in the normal weight range now, for the first time in over 6 years, I don't get food cravings ever, and my body fat continues to decrease, while I increase muscle mass. I follow Mark Sisson's Primal Blueprint, while staying ketogenic. I walk about 5-6 hours a week, lift weights per Mark's plan twice a week and do sprints once a week.
