Heads Up Health, Patron Content, Ferritin Drop

Heads Up Health

I met David Korsunsky last year and was instantly a fan of his product, Heads Up Health (HUH). His staff has been tenaciously aggregating all these different medical systems and lab result formats into a single repository that’s really easy to work with. Obviously, as a data fiend, I was immediately interested.

This weekend HUH released a guide that makes it easy to work through my protocol using their system and I’m definitely happy to highlight it. In fact, it’s one of the only ways I know that you could be both tracking your food (say, with MyFitnessPal), while also getting your blood labs (through, say, Quest Diagnostics) and have them all come together in the same place. This would also make it easier if you wished to share your data back to us here (which I hope you do, as always) as it will be in a standardized format, thus making Craig’s life easier.

Full disclosure: Like the keto shake companies, HUH offers support for my research in the form of products and service, but in no way do I have any financial interest or relationship of any kind. I’m funded by individuals like you via Patreon or direct donation only.

Patreon Progress

I find it laughable that I was so reluctant to start the Patreon page before now. Mainly, I didn’t want any of my research to be pay-to-see, so I kept putting it off. But I got a lot of good advice from others on simply having patrons have access to the behind-the-scenes and a lot of my casual process. A lot of it is rough and incomplete. At times just stream of thoughts like the Vlog.

Yet this is what makes it work so well. Patrons are kind of like the crew that’s on the set of the movies before they come out.

Moreover, I’m finding some other content to slip in — like my Davehead pizza making. 🙂

Ferritin Drop

I’ve mentioned several times that I’ve had “mysteriously high Ferritin” in the 550s. Indeed, I’ve ran the gambit checking iron levels, oxidative stress, etc. to no avail — everything appears normal. But in my most recent labs, my Ferritin dropped to a 303 ng/ml (ref range 30-400).

Why? I have no idea.

But if my coming labs have me back in the 550s again, you can be sure I’ll be doing a forensic deep dive on everything I ate and did in the days leading up to that original 303 test.

There seems to be more noise than usual with Ferritin readings. Specifically, the higher it reads the less reliable it tends to be. A 200 point difference in consecutive readings is not unusual. A couple points of note in this regard. I wonder if its only a coincidence that the lab method accuracy is a function of its relative importance to conventional medicine. Most doctors think elevated Ferritin is a big nothing if all your other iron blood work is ok. I also wonder if they would continue to think this if pharma had a pill that could reduce it?… Read more »

A ferritin of 303 is still high, do you have your iron saturation %? Have you checked your genes for hereditary hemochromatosis ?

Dave, I have been on keto for over a year and a half now (and before that Paleo for a couple of years). Your experiments prompted me to get my first NMR a couple of months ago, and like you I was freaked out by the results. That lead to more and more tests – and even more contradictory results. I have a CAC score of zero (scanned several weeks ago), but high hs-CRP, high LDL-p, high small LDL-p, high trigs, high oxLDL. Normal LP-PLA2 (I think… there are different reference ranges depending on who you want to listen to… Read more »

FYI I just got my blood test results from this weekend — GGT 8 IU/L, Ferritin 189 ng/mL, and fasting insulin 1.9 uIU/mL, so these aren’t bad numbers. Ferritin on the high side, but not sky high like yours.

I am really confused by my high oxLDL (67 U/L), and hs-CRP (between 3.48 and 6.97 mg/L) numbers. They don’t make sense to me at all.

Thanks for all your research — it has been very enlightening!

Dave, Here are the results of the 3 NMRs I had: 6/17/2017: LDL-P 1627, LDL-C 115, HDL-C 41, Trigs 203, Small LDL-P 1168, LDL Size 19.7 6/21/2017: LDL-P 1730, LDL-C 129, HDL-C 40, Trigs 182, Small LDL-P 1036, LDL Size 20.1 8/25/2017: LDL-P 1737, LDL-C 119, HDL-C 44, Trigs 122, Small LDL-P 1084, LDL Size 20.3 The first two NMRs are only a few days apart because I couldn’t believe the results of the first! The only carbs I eat are the cruciferous or leafy green variety, I don’t eat anything with omega 6 vegetable oils, never smoked, eat twice… Read more »
Great paper! That puts my latest hsCRP in context, too. I agree CAC is the last word on ~10 year risk. However, it measures the cumulative amount of atheroschlerosis (above a pretty high threshold) not the rate of change. It’s also an expensive test in terms of radiation and convenience. There’s a lot more to be learned about what cheap tests are best for measuring its progress. LDL (in its many flavors) is likely a red herring. oxLDL, hsCRP, 2-hour insulin, TG/HDL all might be reasonable candidates. If Tucker Goodrich is right, I also want to find the best Omega-6… Read more »
Hi Craig, Just how fast does atheroschlerosis show up on a CAC scan? From my understanding, 10 years is the zero to high risk estimate. I would expect that if a person is suddenly doing something that is not so heart healthy it would show up much sooner than that. In my area a CAC is not that inconvenient – only in the respect that my state requires a prescription for one. The time to take one and monetary cost is the same as a NMR. Radiation, yeah that could be a different story, I don’t know. Nevertheless, I have… Read more »


How long? Years, probably. Most everyone agrees that SAD is the worst possible diet, and it takes till age ~40 to show up there. Here’s a link: http://onlinelibrary.wiley.com/doi/10.1002/clc.22539/pdf

Why would anyone swap out nutrient dense animal foods? Seems unhelpful to me, too. They certainly don’t appear to be the root cause of atherosclerotic. IMO, any advice that is chasing intermediate bio markers and ignorant of the root cause is probably not worth listening to.



Serum ferritin may be a marker of cellular damage.

Hi Dave, I was diagnosed with high cholesterol for the first time this July 2017 with the following numbers: TC 275 TG 153 HDL 73 LDL 171 After eating a high carb, low fat diet for about one month (Aug 2017): TC 225 TG 82 HDL 70 LDL 138 I’ve been on a low-carb(<25 net carbs per day), high-fat diet for the past 8 weeks and my LDL skyrocketed!!! Here are the results from my most recent labs from October 2017. I am 33, 5'6", and 148 lbs. TC 339 TG 92 HDL 76 LDL 244 From my research it… Read more »
