Blood Pool – Reader Contributed Test Results

Note from Dave–

I’m so happy this work by Craig is finally going up on the site. There was an extraordinary amount of work put into this post, not just in the writing and visuals, but in the meticulous effort he has put forth in mining all the data throughout the site. Extra thanks to Matt’s amazing contribution as well in processing and developing the data set.


Introduction

Readers of this blog often share the results of their test results in comments, tweets, and emails. I’ve been collecting and labeling these into a dataset.  This article presents a summary of the nearly 200 data points extracted from the comments through October 1st.

Special thanks to Matt Allington who put together the interactive visualizations for this post.  Matt is a Power BI reporting professional (and LCHF advocate) at http://exceleratorbi.com.au.

Lipid Scores

Looking through the comment history, I found the most consistently reported metrics were those from a basic lipid panel:

  • Total Cholesterol (TC),
  • Triglycerides (TG),
  • High-density Lipoprotein Cholesterol (HDL-C)
  • Low-density Lipoprotein Cholesterol (LDL-C)

What’s great about this quartet is you can use the Friedwald equation to verify their consistency or to interpolate the missing fourth score, if not provided.

Units are also easy to detect and convert.  The most commonly used units are mg/dL in America and mmol/L in Europe.  I made a heuristic to guess the units based on their range, and converted everything to mg/dL for display purposes.

Other test results were much less common. These included particle counts (HDL-p, LDL-p), glucose, HbA1C. See my previous post for recommendations on the best tests to get.

The Data

Caveats

I recommend reading any study or presentation of health data with a grain of salt. In this case, take two:

1. Bias – These data were self-reported, not scientifically sampled. I would suspect that most readers found this site after switching their diet to LCHF, and probably after getting a high cholesterol score.

2. Accuracy – This data is not independently verified. In very few cases have I actually seen the corresponding Labcorp/Quest report. Contributors may also have misremembered or made a typographic error when submitting their comment.

Commenters on CholesterolCode.com reported an increase of 95 mg/dL LDL-C on LCHF compared to a standard diet. This makes intuitive sense, since the primary job of the lipid system is to deliver TG energy, and LCHF uses more energy from fat, so you’d expect more “boats” in the blood.

However, due to increased HDL and decreased TG, their reported TG/HDL ratio decreased by 0.8. Although most doctors will panic about 100 points of LDL-C, TG/HDL is a much better metric. So just judging from this data, on average LCHF dieters are at lower risk of CVD than standard dieters.

HDL versus LDL

Here’s the scatterplot of LDL and HDL, interactive link here.

In this chart you can clearly see the increased LDL for LCHF (black dots) compared to Standard (red dots). The gain in HDL is visible too, but less obvious. Although there are only 3 data points, Zerocarb (yellow dots) stands out for having among the highest LDL.

HDL versus TG

Here’s the scatterplot of HDL and TG, interactive link here.

In this chart, you see the LMHR cluster (LCHF in black) in the <100 TG, >100 HDL zone. I’d be most concerned about the health of the cluster of in the 200 TG, <50 HDL zone (mostly Standard diet in red).

How to Contribute

Want to have your data included in the next version of this post? Glad to have you onboard, citizen scientist!

The easiest way is to post a comment to this blog (on this or any article).  In the content, include the 4 numbers of TC, TG, HDL, and LDL keeping the same units. Also, include whatever context is relevant, but be sure to include your diet.  Here’s a sample:

I’ve been on a low-carb, high-fat diet for the past 12 months.  Here are the results from my most recent labs from September 2017.

TC 350

TG 100

HDL 80

LDL 250

If you also happen to have results from your previous diet, we’re excited to see the change. Just include the old numbers and context in a second block, similar to the first.

The Nitty Gritty

Labels

I used the context of the comment thread to try to assign labels to each data point. I wanted to know the the diet, lifestyle, exercise, date, and any other commonly-reported factors that might influence the results.

The primary label I consistently applied is the diet.  Here, I assigned to one of 4 mutually exclusive categories.

Standard – Broad category of diets that follow the food pyramid’s advice to emphasize “fruits, veggies, and low-fat dairy”. Typically <30% of calories from fat.

LCHF – Broad category of diets that limit carbs and embrace fat. Typically >50% of calories from fat.

Zerocarb – All-animal product carnivorous diet.

Fasting – Any fast of 3 or more days leading up to the test.

 

I noted other labels, but their reporting was more ad hoc:

Duration – When available, I added a duration as a qualifier to their primary diet.

Exercise – Anything from endurance, strength, high-intensity intervals, to vigorous walking.

IF – Intermittent fasting. Any form of time-restricted eating including 16:8, one-meal-a-day, alternate day, etc.

Test <X> – To distinguish multiple tests in a simple post.  Typically X will be a year.

Losing Weight – If the contributor reported a period of weight loss during this test.

Lowcal – The contributor reported lower-than-usual eating leading up to the test, as per the Feldman protocol.

Highcal – The contributor reported higher-than-usual eating leading up to the test, as per the Feldman protocol.

Non-fasted – If there was any reported eating in the 12-hour window before the test. These points are excluded from calculations.

Duplicate – If the contributor posted the same test result in multiple comments. These points are excluded from calculations.

Methods

I downloaded the raw comment database and wrote a script to process the data.  The script worked over a csv data file with the lipid scores, lifestyle tags, and thread context.  It generated an updated version of the data file with standardized units and an html page with the scores highlighted.  It could also generate rows for candidate comments that looked like they might have a data point. In the end, I still had to type numbers into a sheet, but I had some nice tools to validate my work.

    I’ve been on a low-carb, high-fat diet for 48 months. My most recent labs:
    TC 259
    TG 80
    HDL 64
    LDL 179

    1. Craig

      Looking good, thanks!

  2. Phil

    Happy to share regular multi year data pre and post 12 mo LCHF . Please advise email address for data .

    1. Cherry

      I can do multi year too – for me it shows the progression to diabetes and recovery back to normal

      I’ve been on a low-carb, high-fat diet (60%) for the past 12 months. since diagnosis.  Here are the results from my most recent labs from AUG 2017. WAS on standard ( actually low fat ) since forever before that . Hba1c 90=> 42 in same period 30kg down.

      LCHF HCLF
      TC 166 216

      TG 71 238

      HDL 61 40

      LDL 212 297

  3. Jake

    Here are my most recent lab results (taken in August 2017) after approximately 3.5 months of LCHF (or more specifically macros from the ketogains calculator). During that 3.5 months of LCHF I lost 18 pounds body weight. 49 y.o. male, 6′ tall, 185 lbs

    TC – 411
    TG – 74
    HDL – 72
    LDL – 324

    other #s
    hs-CRP – .6
    HbA1c – 5.1

    In mid-august I switched to ZC, and will be getting bloodworm done in November to see what (if any) change occurs in those numbers. I’d be happy to add those when I get them done.

    1. Craig

      Those number’s look great, thanks for sharing! You’re just a few HDL points away from Dave’s LMHR. Are you still losing weight? How about exercise?

  4. Alex

    Numbers 2 years ago
    Total cholesterol 197
    Triglycerides 72
    HDL 61
    LDL 122
    VLDL 14
    Number from last week after 2.5 months on keto
    Total cholesterol 250
    Triglycerides 54
    HDL 68
    LDL 171
    VLDL 11

    Hyper responder range? Not sure, but seems I’m trebding that way. Started keto for the long term health benefits. Right now really lean ~10% BF started out ~18% BF. Work out every other day with weights and work an active job ~12 hours a day. Also doing IF 16/8 since I’m just not hungry since starting keto. I eat 2x a day. Trying to gain weight back that I lost so around 3000 cals a Day net carbs ~20g, ~240g fat and ~115g protein. blood glucose fasting ~80 and ketones .5 – .9
    What don’t u guys think?

    1. Craig

      That’s a pretty typical before and after numbers. Looking very healthy, congrats on the great progress!

      I’m also “thinner than my doc wants”, but I’m the same as I was in college. I think I just have a low set point on weight. I might try active muscle bulking next year.

    2. Al

      Hi Alex

      Looks like you’re similar to me. I’m 6% body fat and exercise a lot, getting enough animal protein is key (fat will naturally increase too). This is what I’d do… You don’t give your weight/age but consider taking your protein up to about 140g if you’re around 70kgs. 115g looks too low to maintain solid muscle. Also make sure you get 40-50g protein per meal – could try going back to 3 meals per day. Add more meat, fish, cheese and eggs… and less veg.

      Just get your protein level right. More protein on non-exercise days too, interestingly enough.

      Hope this helps

  5. Sam

    Been on Primal/Paleo 2010-2013.
    After that ZERO processed food, Moderate Carb/Moderate protein/Moderate Fat (mostly saturated). Don’t really count anymore.
    Age 60 years – Activity level :- 1 Hour of walk everyday, otherwise sedentary.

    Latest Bloodwork:

    TC – 201
    TG – 85
    HDL – 47
    LDL – 142

    Doctor is pushing Statins as LDL and TC “Beyond Range”

    1. Craig

      Thank you for sharing, and congrats on cutting the processed food. IMO that alone is 100x more effective at improving your health than anything in the pharmacy.

      If your doc might listen to reason, I’d offer to get some additional tests as a “second opinion”. I’d expect you’d do pretty well. Here’s the article I wrote up on that http://cholesterolcode.com/lab-testing/

      e.g. If the doc thinks a) LDL -> b) inflammation of arteries -> c) atherosclerosis -> d) heart attack, then show him/her b) hsCRP, c) CAC score. If those 2 are ideal, then their logic is either wrong, very slow to manifest, or doesn’t apply to you.

  6. bill

    I’ve been on a low-carb, high-fat diet for about 7 years. Here are the results from my most recent labs from August 2017 I’m 63 years old and I exercise at low impact 2-3 days a week.

    Thanks Craig,

    The hsCRP is 1.8 in the same report – CAC was not examined.

    However, I have a few markers that are off:

    Ferritin – 168
    Red blood cell count – 5.99
    Hematocrit – 51.7
    Estradiol – 43

    My guess is that these are pointing to excess iron. I went to donate blood, but they wouldn’t take it as I had a recent trip to South Asia – Apparently one has to wait 2 years after a trip to that region before they consider your blood safe from undetectable parasites. Any advise on any other strategy to reduce iron.

    1. Dianne Thomason

      Sam – I believe your doctor can write an order to have have blood drawn. Your blood would not then be used for donations.

    I have been low carb for a couple of years and fasting daily (14 – 20 hrs) for about 11 months. During the 4/20/17 blood draw, I ate 2x/d on workout days, at once a day on non workout days, ate 10-12 egg yolks daily (choline), I lifted weights 5x/wk and I was limiting my protein to 50-60g/d. Today I still eat 2x/day, eat about 100g/d of protein, 4 whole eggs daily and workout 6x/wk. I am 146lbs and recently started leisurely walking for cardio. Lab results below:

    Here are my results. I started low carb on January 2, 2014. I’m currently eating near zero carb. For instance, yesterday I ate basically all meat and some olives. However, I still eat some vegetables.

    Date TC LDL HDL TGs TG/HDL
    06/25/14 175 119 37 113 3.05
    06/02/15 202 129 49 120 2.45
    09/18/15 224 152 40 158 3.95
    02/29/16 168 103 52 65 1.25
    03/04/16 188 121 36 157 4.36
    10/31/16 195 112 54 147 2.72
    11/14/16 163 96 55 58 1.05

    These were all 12+ hours fasting, except that the 9/18/15 and 3/4/16 were after 4.5 days fasting. The test on 9/18/15 caused my doctor to freak, and at the time I took the test after 4.5 days fasting because I thought that would make the numbers better…which I now know to be a mistake. So, I tested to see what would happen if I took a 12 hour fasting sample (2/29/16) and a sample later in the same week after 4.5 days fasting (3/4/16).

    In this time period, I’ve lost 50+ pounds. I also started intermittent fasting in about March of 2015, and I’ve used various IF schemes. I’m currently fasting 36-40 hours twice per week and one 20-24 hour fasting per week, with skipping breakfast most days. I take breaks though of 1+ weeks duration to give my body a rest.

    You can see that these are all over the map, even if you cut out the two outliers caused by fasting 4.5 days. The only thing consistent (assuming the outliers are cut out) is HDL keeps improving.

    I plan on doing Dave’s 10 day test and segueing into a test of Ted Naiman’s higher protein low carb diet to see what happens, but I’m waiting for a continuous glucose monitor to arrive. That should be here within a few weeks. I’ll report back once those tests are taken.

    Date Total g/l HDL g/l LDL g/l Trig g/l
    10/24/2007 2.49 0.39 1.83 1.37 Paying no attention to diet, lots of junk food, ~89kg
    02/18/2011 2.34 0.47 1.69 0.92 Efforts to eat less/better + exercise, ~83 kg
    06/20/2015 2.11 0.46 1.46 0.96 Efforts to eat less/better + exercise, ~86 kg
    09/20/2017 2.68 0.68 1.84 0.81 LCHF for about 14 months, little or no exercise, ~75kg

    The doctor expressed concern about the increased total and LDL values from the last one but didn’t suggest any intervention.

    Dave, really enjoyed watching your video from Low Carb Down Under.

    Here are my results. I started moving away from sugar, low-fat, and high-omega-6 oils after the August 2008 reading. After many baby steps, I was mostly primal/LCHF by 2012 and have been since. Have been cycling 3-5x per week 30 mins 80% of the rides — other rides range from 1-5 hours — plus 1 hour/week with personal trainer workout. No IF or fasting (yet?). Lost 20 pounds from August 2008 over 12 months. The LDL below is calculated — if I had Direct LDL, I mention in Notes.

    Date TC LDL TGs HDL TG/HDL Notes
    10/31/89 229 158 105 50 2.10
    08/15/08 263 173 90 72 1.25
    12/10/08 264 170 58 82 0.71
    08/05/09 245 158 31 81 0.38
    06/28/12 280 168 81 96 0.84 Direct LDL = 154; LDL-P = 1693; sdLDL = 41 (NMR)
    08/01/12 271 153 76 103 0.74 Direct LDL = 139; LDL-P = 2482; sdLDL = 33 (NMR)
    12/08/15 294 199 136 68 2.00 Direct LDL = 201; LDL-P = 2774; sdLDL = 41 (NMR)
    09/27/17 313 199 137 87 1.57

    Also had a CAC Score of 0 on 01/08/2013.

    Hi. Just discovered you through a podcast – so interesting!
    So I’ve got a life insurance medical exam coming up and want to reduce my total cholesterol.
    According to my tests last year my doc said I should consider a statin (I never followed up on this and do not take any medication)
    Last year my #s were: total (237), hdl (69) triglycerides (53).
    I’m 38 yo female, not overweight.
    I don’t eat exclusively LCHF, though I lean that direction for sure. I’m probably closest to paleo more than anything else though i do eat occasional GF grains & raw or goat dairy.
    Would you recommend this 3 day high calories high fat approach for myself & this situation?
    Also how do I determine ‘high calorie’?
    And must the blood test be in the AM on the 4th day?

    Thanks for your help – greatly appreciate it & look forward to leaning more!

    My lipid numbers in 2011 when I was eating lowish (50-100) net carbs:
    TC 169
    LDL 87
    HDL 63
    Trig 97

    In 2017 after eating keto for a year:
    TC 166
    LDL 41
    HDL 117
    Trig 39

    And the above numbers are correct. I did not mix up LDL and HDL. And I don’t drink alcohol so that’s not the reason for the high HDL. I don’t know why they are at these levels but my doctor says I’m pretty much heart attack proof. I am a 67 year old female. I’ve lost over 100 pounds in the past two years and am now at normal weight (BMI 23.7). I exercise (yoga, HIIT, walking, and strength training) for 1-2 hours per day. I eat less than 20 net carbs, about 50 gms protein and 80-100 gms fat totaling about 1100-1200 calories a day. I do 16:8 hour fasts daily. I was diagnosed with T2 diabetes seven years ago with an A1C of 13.6. My last one was 5.4. I was taking the max dose of two high bp meds and my bp was still around 140/90. Now I take none and it’s around 115/55. I sleep well. I’m happy. I’m not hungry.

    Please advise. I need to get another blood test soon. My last one was high and Dr wants to put me on statins which I resist. I am 5’6, 8st 11, 74 years old, fit and in good health. My cholesterol has always been high ish but has jumped from 7 to 9.5 on LCHF diet.
    You suggest eating high fat for 3 days prior to blood test. But should this be a fasting blood test? When should the last food be consumed before the test?
    Thank you

      You have at least 2 options.

      Option 1, is to get more/better tests, so you can make an informed decision without being stuck on LDL-C.

      Option 2 is to use Feldman Protocol to game the short-term variability of LDL-C to get your Doc off your back.

      Or you can just looked the effectiveness and consequences of whatever is being suggested and decide based on that. Keep an eye out NNT (number needed to treat) and NNH (number needed to harm).

    My numbers on LCHF (in mmol/l):

    HDL 1.49

    LDL 3.81

    TG 1.51

    TC 5.1
