It's been almost two years now on being primal. I got my most recent labs back, and below are my previous tests for comparison:
Total Cholesterol: 237 - "Still Bad", but better.
Triglycerides: 42 - still "good".
HDL: 94 - higher, which is still "good"
LDL: 135 - significant drop but still "bad". However, it's right near the border since they want it less than 130.
Chol/HDLC Ratio: 2.5 - lower and still "good"
One thing that did come up out of the ordinary was a low platelet count. It should be 140-400 thousand, and mine was 123. My doctor doesn't think there is any significance, but wants to check it in three months. I have no idea why it would be lower.
Overall, I am very pleased with these results. The one major change I made since October was giving up dairy and potatoes. I still do butter, but no milk, cream or cheese. I still do sweet potatoes/yams and yucca on occasion, but no potatoes. I was giving up dairy for 30 days, but I think I am going to stay off it. Regardless of any effect it may or may not have on my lab results, I feel much better not consuming dairy. Better sleep, better skin, etc. I replaced dairy with coconut milk and cream, which are now a regular part of my diet. One other change, which may have had an effect is that I consume fewer eggs. For the past year or so, I was eating about 4-6 eggs per day. Now I have leftovers for my first meal each day, and only have eggs a few times per week.
Total Cholesterol: 260 - "Still Bad", and much worse since August 2010.
Triglycerides: 38 - down a little and still "good".
HDL: 82 - much higher, which is still "good"
LDL: 170 - Even higher, and still "bad"
Chol/HDLC Ratio: 3.2 - lower and still "good"
Here are my results from end of August 2010, almost 6 months into PB:
Total Cholesterol: 228 - "Still Bad", but not really changed much since April.
Triglycerides: 46 - relatively unchanged and still "good".
HDL: 61 - a little lower, but still "good"
LDL: 158 - Even higher, and "bad"
Chol/HDLC Ratio: 3.7 - "good"
This is from April 2010, about 6 weeks into Primal Blueprint:
Total Cholesterol: 217 "Now Bad"
LDL: 143 "Now Bad"
Chol/HDLC Ratio: 3
My readings from pre-primal in July 2009 which were pretty consistent on my CW diet:
Total Cholesterol: 145
Chol/HDLC Ratio: 2.5
All of these are well within the "good" ranges.
