Fatty acid ratio analysis for me and for wife
First one is mine, second is wife's.
OmegaQuant is not available where we live, but I've found something which should be the same. It also analyzes red blood cell membrane's fatty acid content (although this is done by drawn blood, not finger prick). Done by Synlab (and ultimately by Eurofins). As we live in Hungary the results are in Hungarian, but the names are mostly matching with English and obviously the shorthands are the same.
Blood was drawn after 14 hour of fasting. Both me and my wife did the test, which can be interesting not just because different genders, but also because she has higher bodyfat (even accounting to gender difference, she is around 38%, I'm around 20%). I sort of expected that she will have higher LA, or at least some clear difference between us, but... our result are practically the same. Now keep in mind that we do eat in the same way, 95% of our meals are exactly the same food (in different quantity).
About us: tl;dr: keto since 10 years, avoiding seed oils since 8 years, but ate high pufa meat (pork, chicken, duck).
Longer version: we are eating some form of ketogenic diet since 2016. Initially it was "standard keto", so you eat whatever you want, just make sure to eat less than 20g net carbs. So it contained lot of seed oils (mostly in form of mayo), but we already ate a lot of butter and hwc. But we were not aware of PUFA and similar topics back then so it was mostly by accident. We started mainly for weight loss reasons. Which initially was pretty successful, but after roughly a year and a half we got plateaued. Partly because of that and partly because of curiosity we tried carnivore (well, back then it was called zerocarb) starting at 2018 January. We totally stopped eating seed oil directly (as it's not animal sourced), but living in Hungary most of our meat was coming from pork, chicken and duck (beef is expensive here and doesn't even taste good compared to more "beefy" countries). At this point we also stopped eating any kind of supplement (no vitamin, no magnesium, nothing from pills or drops or whatever. Only food). Also from this point for practical reasons the amount of ready-made food or processed food or any eating out was reduced close to zero. 95% of our meals was and are made by us from whole food / raw ingredients. When any processed food (like sausages, or cheese, etc.) we made sure to buy only anything with sensible ingredient list (i.e. similar as if it would be home made). But these stayed over the years be exceptions, never daily (or even weekly) food items.
In the end carnivore was not totally successful for us (later we realized that we was not eating enough fat), and we started to drink too much milk, also we occasionally ate some gluten in form of breaded meat (made at home, fried in lard). In the ended we gained back a lot of weight (before on keto we shed 20-30 kg). Regardless it was successful in other sense as we realized which food items causing problems for us and which are not (or less).
So we decided to clean-up our diet. There was some adjustment period, but at 2020 March we upped fat intake to 2:1 fat:protein ratio (which also resulted in lower protein, into the 80-120g / day range), ditched diary, except for butter (i.e. KetoAF / PKD). But our main food source from that point was fatty pork meat (ground pork, 30/70, so no additional fat needed for 2:1 fat:protein ratio which we found works the best for us).
This lasted roughly until September of 2025 when inspired by exfatloss's diet we tried adding back some form of dairy. My wife even tried the exfat150-ish for a month (it didn't work for her, but it was a pretty "dirty" try). But beside that our main meals were still from fatty pork to the extent that from weekly 21 meals ~16-18 were from purely ground pork (no added spices, no sauce, just baked in oven or pan fried in lard). The remaining were duck breast (with skin), sometimes (beef) steaks, chicken (legs or wings) and eggs. All food is supermarket bought, nothing fancy. Only exception is egg, which is still supermarket bought but bio, which in EU heavily regulated and means that the hens actually out on pasture (and so hopefully eat a bit more of their natural diet).
As we read more about the problems with LA we decided to stop eating fatty pork (lean pork stayed on the menu). I wanted to do the test before we did that, but life happened, so we started to reduce pork fat consumption 1.5 month before the blood drawn. But also life happened (i.e. grill season, which means lot of sausages here, which means... pork fat) so we still ate it, but instead of 99% of the meals, only for like 50-60%.
One additional thing to add and it's true for most part of this last 10 years: our diet was never totally strict continuously. This means that we was 100% strict for a streak ranging from 2 weeks to 3-4 months and then a short period (ranging from 1-2 days to 3-4 weeks) of "dirty" version of it. What dirty exactly meant varied, but usually meant higher carbs (still lower than 100g per day, closer to 50-60 on average) or eating foods not included in the then-current diet (for example eating 1 apple daily for like 2-3 weeks one time during PKD). These were never really planned and usually we reversed them when we started to notice or get bothered by adverse effects eliminated by the strict versions (weight gain, reflux coming back for wife, asthma coming back for me, worse mood, etc.). In some way these resembles exfatloss's refeed days, but in a much less structured and less intentional way.
Anyhow: for the last 6 years 90% of our fat source was pork. And while in Hungary the quality of pork should be better than in the US, I expected that even in the best case we will have LA levels of somewhere around 14-16%. But more likely 20%+.
Obviously the test shows different, with my wife having 11.7% and me having 10.8%. What is interesting though is that the reference range for LA for OmegaQuant and Eurofins' report are vastly different, latter having 8.6 - 13.2%. Unfortunately I could not find anything how the reference range is determined for Eurofins (for OQ it is based on US population).
I'm not that surprised on the low omega-3: as I mentioned we don't eat grass fed or anything like that, and also we don't eat fish (we eat it like 1-2x a month when we feel for it, but even then it's not fatty fish). Still I would have expected it a bit better (from the bio eggs and that the butter we buy is from grass fed cows).
The other thing I'm surprised is the arachidonic acid. From exfatloss's blog post about people with low LA ( https://www.exfatloss.com/p/omegaquant-endgame-test-results-after ) I've seen that those people tend to have higher AA, but our is even higher than their with 19.1% and 18.3%. I'm not yet sure of what conclusion to draw from that.
Well, in altogether I'm not sure what conclusion to draw from these results. But at least we have some baseline, as we plan to continue to eat low PUFA (even though we will continue to eat some pork fat as it is almost unavoidable here and on the other hand our LA levels already seem to be not that bad regardless of eating lots of it).
If anyone has any insights or find anything interesting in the results, please let me know :)
