My Blood Work

Edited to correct HDL reference range and add footnotes found in my blood work results - apparently someone was too impatient to get out and mountain bike and forgot to check their work :)

So, in my last post I mentioned the 'helpful' email I received from my insurance company *rolls eyes*; they are so 'helpful' that they are now requiring you to meet their health standards score to save money on your insurance premiums.  You are scored based on your blood pressure, LDL cholesterol, glucose, triglycerides and tobacco use status; if you do not meet a minimum target score, or improve your score next year, your premiums go up.  My indignation over this Big Brother approach and whether it is reasonable, is fodder for another time; I thought some might be interested my blood work as a real life long term paleo/low-carber (sorry, I've only got the last two years on hand). . . 
 
For context - my diet has been 'paleo' for over seven years now, low carb-ish without carb counting; I've entered my diet into FitDay randomly over the years to see where all the values were falling out, but my diet is pretty consistent, so I don't track day-to-day.  Last fall (again, for context after my 2014 blood work) I made some minor changes in my diet to shift into nutritional ketosis, confirmed via urine test strips - or, as I saw in a comment the other day, measuring my peetones - heh!  Slightly less protein and slightly more fats, primarily from avocado, macadamias, coconut oil and butter; no significant changes in my produce consumption, as I was already fairly low-carb. 
 
As for exercise, at the same time that I started a paleo diet, I started weight lifting again.  My experience is that weight lifting is VERY beneficial for my rheumatoid arthritis - likely every bit as crucial as diet; in a future post, I'll discuss more. . .  I started out with pretty low weights, but seven years later, I am lifting literally three times as much weight as I was in the beginning (woot!); lifting sessions are typically 20-30 minutes in duration.  I also started mountain biking again about four years ago.  I ride or lift, on average, four to five days a week.  In the deep winter, when the local trails are trashed due to weather, I mostly lift with an occasional ride here and there when the ground is frozen solid.  In the summer, I mostly ride, with one or two weight lifting sessions a week.    Also, I'd like to note for anyone interested, in shifting my diet toward nutritional ketosis I did not experience any noticeable difference in my exercise performance. 
 
On to the numbers! 
 
Total Cholesterol
2014        2015          Reference Range
186          198            100-199
 
LDL
2014        2015           RR
87            108             0-99
 
VLDL
2014        2015           RR
17            11                5-40
 
HDL
2014       2015            RR
82           79                greater than 59
 
T. Chol./HDL Ratio
2014       2015           RR
2.3          2.5              0.0-4.4
 
Triglycerides
2014        2015         RR
86            54             0-149
 
Glucose
2014        2015         RR
101          103           65-99
 
Hemoglobin A1c
2014        2015         RR
5.4           5.5            4.8-5.6

Footnotes found in my blood work:

**According to ATP-III Guidelines, HDL-C greater than 59 mg/dL is considered a negative risk factor for CHD (coronary heart disease).

**T.Chol./HDL Ratio
    CHD Risk
    1/2 Average Risk    Men-3.4   Women-3.3
          Average Risk    Men-5.0   Women-4.4
    2X Average Risk    Men-9.6   Women-7.1

**Hemoglobin A1c
    Increased risk for diabetes:  5.7 - 6.4
    Diabetes:  greater than 6.4
 
So, I'm thrilled with the lower triglyceride and VLDL numbers.  HDL is still nicely in the very high numbers, keeping my Total Cholesterol/HDL ratio low.  The LDL is outside of the lab reference range, but still below the lower target number of 130 used by the insurance company, so I wasn't penalized for that; it's a shame that they don't include HDL or the Total Cholesterol/HDL ratio in their scoring.  I was penalized for having high blood glucose.  I'm not terribly thrilled with the glucose number, although such numbers are not unusual for those who are very low carb (VLC) and/or in nutritional ketosis.  Peter, Mark and Robb have all blogged about this phenomena. 

It is my understanding that this can be 'fixed' by eating a more moderate carbohydrate diet for a short period, which could be a strategy for next year's blood work to ensure I stay within the insurance company's target score and don't end up getting nailed with higher premiums.  I'm well within the overall target score this year, so there's that. . . On the other hand, I would have expected the A1c number to be a bit lower, and the elevated blood glucose still gives me the willies. . . I know Dr. Terry Wahls advocates a ketogenic diet for a variety of reasons - time to reread that section of her book and confirm whether I want to continue with nutritional ketosis or drop back to my 'normal' low-carb paleo diet. 

In any case, Happy Spring all!  The local trails are finally in good shape and although the weather isn't quite so warm as last weekend, the sun is out - I'm off to ride!
