Well done and thanks! ,'m a retired Clinical lab scientist and was taught to tell patients to fast for 12 hrs before getting tested for lipid levels. When I went for my annual labs the other day, I was asked if I was fasting, but not if I had fasted for at least 12 hours or had cream in my coffee. Someone else commented that the VA doesn't require 12 hours due to blood sugar concerns. So now it looks like many patients are going to have falsely elevated lipid levels.
I recently experienced this at the VA. They prescribed me a statin. I really don't want to take it. But my triglycerides were in the 500s so I was definitely way off.
Oh my goodness, this is just what I needed to hear. I’ve never had high triglycerides in my life until I went carnivore. I’ve always been an extremely healthy person avoid sugary drinks only drink black coffee don’t buy things in packages only buy grass fed and pasture raised and organic and yada yada yada. So I know all the Nono’s and I’ve been very good. I’ve been on carnivore for two months and my Triglycerides were 268! Of course the doctor wants to put me on statins in Crestor for high cholesterol which I believe is hereditary. But the triglycerides are new. But I had just eaten a big steak cooked in butter with lots of salt right before I went in for the blood draw. I forgot about fasting. Do you think that could be the problem?
Thanks to your great research and video, I know why I am a carnivore and my triglyceride test came back 340. I ate a fatty meat breakfast before the test because the doctor didn’t tell me to fast until after the test. From now on I will fast 12-13 hours only. THANK YOU!!!!
OMG, I feel sooooo much better now! I just had the same experience yesterday. My tri number was 364, despite all the other general / overall numbers were good. (I had an impromtu testing. Hadn't fasted. Had a steak and eggs, cooked in butter of course, breakfast.)
One dimension which is important to interpret these values, is if you did lose weight. While I'm on Keto and lose weight my values are high, after plateau and not losing weight, I'm constantly low on lipids.
This means that triglyceride numbers mean NOTHING UNLESS they are linked to TIME. What does that mean for all the HDL/TRIG ratios etc, etc, etc. The body is constantly regulating these things just like your heart rate.
Dave, thanks for being our human pincushion! After listening to your videos, I had an NMR lipid test done this morning. fasting time was 16 hours. Hope this wasnt too long. Test is important to me as I want to come off rosuvastatin, and want to prove to my doctor that my tri's/ldl are the good kind.
Basically if you do not eat then it is always fine. Once you eat it is the problem. That is great to see your lines on that. Thank you, as I can visualize that better for me. I know how to control my next lab tet results after this.
Very interesting that your TG was elevated before the meal! Thank you so much for all of this amazing experimentation, and all of your finger pricking!
You are amazing brother, this is fascinating information and makes perfect sense . One thing comes to mind from the data you present , this also looks like linked to cortisol Spike with circadian cycle ?
That was my thought-- cortisol spike would explain this. Which makes me wonder if someone was stressed out on a morning rushing to get to a lab with traffic, etc, would that possibly spike the trigs even if fasting long enough? I think that triglycerides are likely very dynamic and levels vary throughout the day and night.
I had a fasting cholesterol test and have been on keto for six weeks . My tryglicerades were higher than before keto . HDL went down too. LDL very high. I was worried why this was as expected LDL to rise. GP wanted me on statins. I'm in the UK and I worked out tryglicerades 120 .This is very interesting.
My cholesterol skyrocketed from 5.8 to 9.1 From March to oct Seeing a lipids specialist Got a lipoprotein (a) test …nasty sticky cholesterol Waiting for results Trigs are low normal 3
The US VA Health System no longer requires 12-14 hr fasting before blood tests. Supposedly this decision was to avoid 'dangerous low glucose levels' on some individuals. Again, this started about 5 months ago this year. Wanting to avoid low-glucose conditions is fine but, how many veterans will be placed on statins or other medication because their results are skewed because of not observing the long-standing fasting window? I personally, will continue to observe 12-14 hr fasting before my lipid and thyroid panels at the VA. My triglycerides have this exact behaviour described on this video when I don't fast exactly 12-14 hrs. I also try to make my meal low carb but also low fat.
Thanks for sharing. This is important and disturbing information. I retired from the VA after working in the lab for 34 years. This is malpractice. I am disgusted with how spineless pathologists have become. It is their job to police medical staff and medical administration to ensure quality lab testing and surgical procedures are done. (Same goes for supporting mask wearing and not performing autopsies on any C19 patients. They knew those policies were wrong and failed us).
Begs question of rate of gastric emptying relative to macros. I know nuclear medicine gastric emptying studies have a standard meal eggs and toast and o.j., but curious if there are any studies comparing other macro patterns (high fat or high protein). Protein isnt really fuel like fat/carbs so I would hypothesize that it empties from stomach slower to moderate absorption which would then push back Trig levels temporally.
Love you work here. Have you studied what happens to lipid levels at 12 hours with and without exercise in the last few hours of the fast? i.e. should I avoid exercising while fasting prior to a lipid panel? I'm fat adapted and on a keto diet, and do a 16/8 fast most days, but my last lipid panels were high, taken at 16 hours of fast with an intense 1 hour 15 minute workout just prior to blood draw. Next time I'm skipping the workout to see if things change.
Oldskool Driver I fasted 19.5 hours before a recent blood test and my triglycerides were 190. All my markers are fine besides that. I was shocked along with my LCHF doctor. No idea what to do at this point. I was zero carb up to that point for 4 solid months with absolutely NO cheating whatsoever and I DID have a very intense workout the day before. Don’t know what to think at this point 😟
Only because your trigs dropped after 9 am ish the first thing that came into my mind was Cortisol. I get the dawn phenomenon. If I check my blood sugar after 8 am it is always high anytime after or before it is lower. I couldn't help but think maybe it could be something to do with a release of fat not unlike the release of blood sugar in relation to the hormone surge around this time to wake and get the body going at the time.
When you burn fat, removing the fatty acids from the triglycerides leaves the glycerol. The glycerol makes it way back to the liver where it's converted to glucose via gluconeogenesis.

Same here. I GUESS mine due to increased sat fats and maybe because I went from 3 to 5 eggs a day. Suspect some of us do better on mono fats than sat fats....?
WOW! Amazing! I want to do these hourly tests after HIIT, weightlifting and running (each done on a different day) - see what difference plays the intensity of training... But currently I don't have $800 to spend on this... Great work and thank you for sharing the results!
Question which raises for me. If that is your regular eating pattern your triglycerides are high for the most time of your day. If prolonged high Triglycerides are considered to be bad for your health for the reason of beeing high not for the reason of beeing a marker for something else. I think it could be unhealthy. For sure it seems to be high because of the food you ate and considered all the meals cause that high Triglycerides. They are high from 11:00 to your last meal plus a maximum of 12 hours. If we assume 11 hours after last meal as average. 18 hours of your day the Triglycerides are over 200 and 6 hours below 100. I think the 12 hour water only fasting rule for your bloodtest has its reasons to divide sick from healthy. But what needs to be think of is if the prolonged very high levels caus problems themselves
Fascinating content; thank you! Out of curiosity, what does it mean if your triglycerides are 0.60 or 0.88 mmol/L after 12 hours of fasting? I'm assuming it's good, but what does it mean? Is it simply telling me I don't have a lot of fat floating around in my blood? Or does it mean something else as well?
I fasted 19.5 hours before a recent blood test and my triglycerides were 190. All my markers are fine besides that. No idea what to do at this point. I was zero carb up to that point for 4 solid months with absolutely NO cheating whatsoever.
well the point is unless ur always fasting, ur triglycerides are gonna be up all the time. Which may not be healthy. To value ur health only when ur fasted is only relevant if ur always fasted. If your someone who is gonna eat throughout the day, then you can safely assume, your levels will always be high, which to me, sounds not too great.
My experience on carnivore is that I do not want to eat more than once a day. I eat one big meal, usually beef and eggs. Sorry I have no data now. But it appears that omad and carnivore go together. I will try to help with data if I can. Very interesting data.
I’ve learned I can’t do one big meal on carnivore anymore. I was getting intense stomach pain - my body couldn’t break down that much protein at once. 110g of protein in one sitting is just too much for certain people. I had to restart my entire diet with bone broth and reintroduce food slowly to get my stomach and digestion re-set. Then I started doing smaller meals and it improved my carnivore experience tremendously. Until then, i wasn’t sure I could make it on carnivore because I was in so much GI pain.
Sooo. If Trigs are so variable, does it invalidate the trig/HDL ratio to determine if one has small dense LDL? OR is that Trig/HDL ratio based on FASTING numbers? I am confused. My fasting trig/HDL ratio is 1.1, which puts me in the "you have no small dense LDL" category. This video now has me concerned. Mr. Feldman or anyone else have any opinion other than get a lipid subfraction test?
How does this relate to people with Familial Hypercholesterolemia? Very interested to see how diet effects these triglyceride levels. From my own experience, it seems that the levels are greatly affected by what the person ate the night before they fasted and especially what they ate right before.
How accurate are those at home cholesterol monitors to begin with? I heard from product user reviews that results can vary dramatically from sample to sample due to pipette sampling errors or different volume of blood sample self drawn.
A man possessed, in good way. So important to the data. Get some good rest. Thanks for your commitment and hard work. Lipids - Who knew they could be so fun.
@@erastvandoren You appear delusional Erast. The only way to get LDL as low as you ignorantly preach is to put oxidation-prone oils in your lipid transport system, and give yourself coenzyme Q10 deficiency with the maximal tolerated HMG-coenzyme A reductase inhibitor. This throws the LDLs at the wall and drives heart disease. Lift, do cardio, then eat red meat, fish, eggs and high-fat milk products. This way all of your phospholipids will be oxidation stable, and your lipoproteins will clear from circulation in the indicated way (if that is indicated by your biology).
That explains why my triglycerides were 191 last week when my annual blood work was done. I fasted about 11 hrs max. Last meal was to 7:30 pm. Blood drawn about 8:20 am next day (VA clinic) Could this also affect hdl/ldl numbers?? I’m retesting Thursday through ownyourlabs. Sharing my data to your program.
I was thinking these days, shouldn't people (European, 4-season climate people) go mainly carnivore at winter naturally, resulting in optimal health ? Instead of year round same diet, because of access, that our genes definitely didn't get used to.
Yeah I was thinking about going carnivore keto in the winter and Eating fruits etc in the summer, to build a little bit of bodyfat for the summer, and getting lots of sun, I think eating only meat at all seasons isn't recreating natural conditions. Eating a lot of meat in the summer also seems less necessary since you have stocked plenty of fat-soluble vitamins and B12, and can get vitamin D in the sun. Also would be smarter in nature to let the animals get fat in summer when vegetation is growing a lot, and eat more plants since more are available for us in summer, and eat the animals in winter after they got more fat and nutrition.
You are testing after you wake up. What about the third shifters that work at night and then go to the doctor first thing in the morning? I could get the 14 hours of fasting but I will not have sleep before going to the doctor. Do you think this effect still applies?
@@gregbell9403 I think in order to get a satisfactory lab work results, you have to quit be on keto diet for a few weeks. This May, my TG was 54, HDL 73, LDL 170. I am on keto for about 2 months now. I will definitely switch to regular non keto diet before my next lab work. Because after reading other people’s messages, I know TG and LDL will go extremely high. And if you don’t listen to your doctor and ignore taking Statins, then I am afraid you might be on their bad patient lists and they might refuse to insure you!
Dave, It would be interesting if you can comment on how carnivore affects your ketosis. When I was learning about ketosis, I was focusing only on carbs, but my high protein levels kept me out of ketosis. With 3 meals of protein a day, I'm guessing you are not in ketosis and may need to go to OMAD to get into ketosis. That may be an interesting experiment :-)
Lipid Disaster!! Just got my numbers after 4 months of KetoVore (less than 20 carbs/day) Lost 41 lbs, from 7.7 ->4.5, Insulin 4.38, resistance .87, but lipids HDL 33, non-HDL 332, Trig 208, Calc LDL 290 . I had coffee and cream. 13 from my last big meal. Doctor says thats stroke and heart attack high, wants me back on statins. Help!
It seems you have a Triglyceride rise at your dawn awakening similar to what a Type 2 Diabetic has with blood glucose being elevated when they get up. With Diabetes it is called the Dawn Effect and is a normal thing as your body is giving you glucose (from your liver typically) for energy when you wake up. A healthy person does not have high blood sugars as they respond to their bodies insulin correctly. I wonder if this is similar ?
Was the carnivore diet keto or mainly protein based? From what you ate I doubt it was fat based... More meat than fat it looks to me.... So could it be that protein is more hard to digest? And an other question. Have u done the same experiment with completely KETO or SAD diet? So we could compare?
Question. Doesn't it make sense that your body doesn't actually need all of the lipids (fats) that you are eating, so your TG will be higher? On the carnivore diet you just don't have the time to use all of the fat you eat if you don't exercise. This makes sense to me. It is super interesting, but seems like common sense vs a new discovery.
The point is to fast for at least 12 hours before getting your blood drawn if any lipid testing is going to be done. Sadly, it seems that most doctors' office staff do not tell patients this anymore. The reference ranges are set to a 12 hour minimum fast as that is how long it takes to clear them from the bloodstream to get to fasting level. I eat a high fat diet, so give it 14 hours.
Mine was 840... is that really worrisome? The results say ALERT. been hyper-carnivorous for a year. 95% carnivore with most of the cheats being outright junk food (donuts, icecream, twizzlers), but I was strict carnivore for 2 weeks besides 1 kiwi before getting my blood work. Fasted 13 hours as well.
No, they're made for diabetic sugar addicts with sky high values. If you're eating low carb you most likely have them around 50, in which case the device will just report "
Also, what was your baseline prior to this "test" and were you in ketosis prior to the "test"? Seems like Trigs at 221 at the beginning of the test tells us you were not in ketosis to start. Forgive me if you covered this in the video.
I fasted 19.5 hours before a recent blood test and my triglycerides were 190. All my markers are fine besides that. No idea what to do at this point. I was zero carb up to that point for 4 solid months with absolutely NO cheating whatsoever. So discouraged. Concerned about my health I have two small boys 🙁
gangelo ... similarly, I been low carb for couple years... high cholesterol, high LDL, high trigs... ratios are good, except tri/HDL could be lower... so, gotta lower trigs... not sure how- might have to drop all alcohol as that is the only cheat factor for me.
I had no idea that TGs were so high after meals. I've had low TGs for a while, but now it appears that outside of fasting for 12 or more, they can be pretty high. What does this info mean for those who might not have as high HDLs as we would like? My ratio is pretty good on my fasting lipid tests, but is that misleading?
Mine were high after a fasting test. I was shocked. Also HDL lower all since starting keto . I had high LDL and expected that . I was scared to see this .
@@debbietaylor20 same..tho triglycerides come down from 5.1 to 3.i was expecting better as not had carbs or sugar for months on keto.hdl only gone up .01 and LDL tripled.worried
So we know now that we can make our doctors happier if we come late for blood testing.Thank you for stating that there is another useless blood test - triglycerides. What's left that is still reliable and really important? I guess it's HbA1c and CAC. And maybe insulin too.
A1c ...look at chriskesser.com and see almost 300 comments of A1c out of line. Thyroid readings also fluctuate heavily, there are even books about this. Insulin will be the same, look at the wide reference range Haha...just give it your best shot, pray, and play 👍
I found this video to find out why my triglyceride was measured 198 after like 10hour fasting (and that's when I did my blood test for the regular health check) so I could assume I shouldn't worry about the high index when my HDL abit lower and LDL in a normal range. Hope to hear some feedback from anyone. Thanks
I've been doing keto six weeks and had blood tests and was shocked to see tryglicerades rise and HDL lower. LDL was much higher but I expected that as heard this happens . I was freaked out . My total cholesterol rose to 374 I'm in UK so think I converted it right . I've always had high cholesterol and started keto to lower it as don't need to lose weight but did lose 12 pounds .
I'm always radiating heat when I wake up in the morning, regardless of what I ate the day before. It diminishes to normal levels after a couple of hours awake. Is this elevation of triglycerides in the morning a reasonable explanation for the thermogenesis my body goes through?
How are you taking all these triglycerides test at home? Device, product, info? I been carnivore 2 months and just has test. Everything was horrible. Inflammation through the roof. Triglycerides through the roof. Vitamin D less than 30. HDL less than 35. How is this even possible? Been keto before going carnivore
I have tried the carnivore diet for 30 days after already in keto for 2.5 years. after 3 weeks of pure carnivore I went to get a blood work, my TG was 192! double what I had on keto, and the ratio TG/HDL were 3.2 also double then on keto. I had the test 11.5 hours after last meal. could it be that high because I didn't waited another 30 minutes?
Well done and thanks!

This means that triglyceride numbers mean NOTHING UNLESS they are linked to TIME. What does that mean for all the HDL/TRIG ratios etc, etc, etc. The body is constantly regulating these things just like your heart rate.
Agree. Same with thyroid and even bloodsugar readings - so difficult to pin point things.
This is beyond helpful and explains so much. Wonderful precision and analysis!

you should just come off it if you don't have existent heart disease.
It isn't too long from my experience. 1-2 days fasting would help you more.
Thank you for this!! Now I know why my triglycerides were so high when I had just eaten my ribeye steak 2 hours before my lab work! Phew!

Thank you so much for all of this amazing experimentation, and all of your finger pricking!
I think brain knows what's happening and hormone levels can come from brain prior to actual biochemical/macro triggers.
He had already eaten two meals before that one, so why would it go down? Not enough time between meals to get them low.
You are amazing brother, this is fascinating information and makes perfect sense . One thing comes to mind from the data you present , this also looks like linked to cortisol Spike with circadian cycle ?

Interesting as my hubby's last TG was elevated and the rest of the metrics is looking all good, so this explains a lot! thank you!

Awesome work, Dave! Hope your fingers are feeling better 😆

Fascinating content; thank you! Out of curiosity, what does it mean if your triglycerides are 0.60 or 0.88 mmol/L after 12 hours of fasting? I'm assuming it's good, but what does it mean? Is it simply telling me I don't have a lot of fat floating around in my blood? Or does it mean something else as well?
Thanks so much for this, Dave. Let your fingers rest up a bit! :)
So need atleast 12+hrs before blood tests for TG to go down. But if you fast longer say to 16-18hrs will it go up again?
@The Unknown depending on country you're in that's good or bad 😂😂😂
Not for me .
I fasted 19.5 hours before a recent blood test and my triglycerides were 190. All my markers are fine besides that. No idea what to do at this point. I was zero carb up to that point for 4 solid months with absolutely NO cheating whatsoever.
@@gangelo777 mine were over 400. kinda nuts.
well the point is unless ur always fasting, ur triglycerides are gonna be up all the time. Which may not be healthy. To value ur health only when ur fasted is only relevant if ur always fasted. If your someone who is gonna eat throughout the day, then you can safely assume, your levels will always be high, which to me, sounds not too great.
3 month in carnivore diet. Just tested today. My trig were very high 400+ at 7.30. Never happen before. Confuse me. Want to check again in couple day.
My experience on carnivore is that I do not want to eat more than once a day. I eat one big meal, usually beef and eggs. Sorry I have no data now. But it appears that omad and carnivore go together. I will try to help with data if I can. Very interesting data.
I’ve learned I can’t do one big meal on carnivore anymore. I was getting intense stomach pain - my body couldn’t break down that much protein at once. 110g of protein in one sitting is just too much for certain people. I had to restart my entire diet with bone broth and reintroduce food slowly to get my stomach and digestion re-set. Then I started doing smaller meals and it improved my carnivore experience tremendously. Until then, i wasn’t sure I could make it on carnivore because I was in so much GI pain.
Where can I get a home triglycerides tester?
Amazon has test strips
what are you using to measure your TG?
Sooo. If Trigs are so variable, does it invalidate the trig/HDL ratio to determine if one has small dense LDL? OR is that Trig/HDL ratio based on FASTING numbers? I am confused. My fasting trig/HDL ratio is 1.1, which puts me in the "you have no small dense LDL" category. This video now has me concerned. Mr. Feldman or anyone else have any opinion other than get a lipid subfraction test?
Just make sure you fast for at least 12 hours before any lipid testing and they should be true and accurate fasting results.
How are you testing? What is the device you are using?
So it takes at least 12 hours to get a good fasting TG number.
How do you test your tri’s so easily?
How does this relate to people with Familial Hypercholesterolemia? Very interested to see how diet effects these triglyceride levels. From my own experience, it seems that the levels are greatly affected by what the person ate the night before they fasted and especially what they ate right before.
How accurate are those at home cholesterol monitors to begin with? I heard from product user reviews that results can vary dramatically from sample to sample due to pipette sampling errors or different volume of blood sample self drawn.
Thank you for doing this!
a third meal and so late would destroy my sleep awaking all night long with body heart high!
thank u for sharing this information. good job 👍
So if someone is having a blood test for triglycerides/HDL ratio they should fast for at least 12 hours?
Hey Dave, you forgot to answer Granddad08 question "how did you measure the triglycerides with what machine etc"
Cardiocheck plus
A man possessed, in good way. So important to the data. Get some good rest. Thanks for your commitment and hard work. Lipids - Who knew they could be so fun.
The man can measure, but cannot think.
@@erastvandoren You appear delusional Erast. The only way to get LDL as low as you ignorantly preach is to put oxidation-prone oils in your lipid transport system, and give yourself coenzyme Q10 deficiency with the maximal tolerated HMG-coenzyme A reductase inhibitor. This throws the LDLs at the wall and drives heart disease. Lift, do cardio, then eat red meat, fish, eggs and high-fat milk products. This way all of your phospholipids will be oxidation stable, and your lipoproteins will clear from circulation in the indicated way (if that is indicated by your biology).
How do I test triglycerides at home so frequently ?
how did you measure the triglycerides with what machine etc
Cardiocheck plus
So tempted to buy one of these testers. But the cost per test is still pretty high. I hope these test strip costs come down like ketone test strips.
Nice documentation! Thanks :)
I’m wondering if the spike is due to the morning waking glucose rise that normally happens in the 1st few hours after or during waking.
That explains why my triglycerides were 191 last week when my annual blood work was done. I fasted about 11 hrs max. Last meal was to 7:30 pm. Blood drawn about 8:20 am next day (VA clinic)
Could this also affect hdl/ldl numbers??
I’m retesting Thursday through ownyourlabs. Sharing my data to your program.
Super informative. Thank you! Is it pretty normal to have fluctuating triglycerides on a carnivore diet?
Trigs are very sensitive to weight loss says my cardiologist
I was thinking these days, shouldn't people (European, 4-season climate people) go mainly carnivore at winter naturally, resulting in optimal health ?
Instead of year round same diet, because of access, that our genes definitely didn't get used to.
Yeah I was thinking about going carnivore keto in the winter and Eating fruits etc in the summer, to build a little bit of bodyfat for the summer, and getting lots of sun, I think eating only meat at all seasons isn't recreating natural conditions. Eating a lot of meat in the summer also seems less necessary since you have stocked plenty of fat-soluble vitamins and B12, and can get vitamin D in the sun. Also would be smarter in nature to let the animals get fat in summer when vegetation is growing a lot, and eat more plants since more are available for us in summer, and eat the animals in winter after they got more fat and nutrition.
@@Azazaz426 sounds completely sensible to me
@@Azazaz426 Fruit won't increase body fat, just the liver's. In any case, I really don't see why you'd want to gain fat on purpose..
You are testing after you wake up. What about the third shifters that work at night and then go to the doctor first thing in the morning? I could get the 14 hours of fasting but I will not have sleep before going to the doctor. Do you think this effect still applies?
I'm on keto and I fasted for 10hours and my tryglycerides were 247 was also worried. Gonna have to retest after I fast for 13hours
Same..let know if you get any answers as not carbs or sugar for months also my cholesterol thru roof
You two guys found any answers?
@@gregbell9403 I think in order to get a satisfactory lab work results, you have to quit be on keto diet for a few weeks. This May, my TG was 54, HDL 73, LDL 170. I am on keto for about 2 months now. I will definitely switch to regular non keto diet before my next lab work. Because after reading other people’s messages, I know TG and LDL will go extremely high. And if you don’t listen to your doctor and ignore taking Statins, then I am afraid you might be on their bad patient lists and they might refuse to insure you!
Dave, It would be interesting if you can comment on how carnivore affects your ketosis. When I was learning about ketosis, I was focusing only on carbs, but my high protein levels kept me out of ketosis. With 3 meals of protein a day, I'm guessing you are not in ketosis and may need to go to OMAD to get into ketosis. That may be an interesting experiment :-)
Lipid Disaster!! Just got my numbers after 4 months of KetoVore (less than 20 carbs/day) Lost 41 lbs, from 7.7 ->4.5, Insulin 4.38, resistance .87, but lipids HDL 33, non-HDL 332, Trig 208, Calc LDL 290 . I had coffee and cream. 13 from my last big meal. Doctor says thats stroke and heart attack high, wants me back on statins. Help!
What did you do. What are you going to do? I’m kind of in the same boat.
Nice work! Keep it up.
It seems you have a Triglyceride rise at your dawn awakening similar to what a Type 2 Diabetic has with blood glucose being elevated when they get up. With Diabetes it is called the Dawn Effect and is a normal thing as your body is giving you glucose (from your liver typically) for energy when you wake up. A healthy person does not have high blood sugars as they respond to their bodies insulin correctly.
I wonder if this is similar ?
Actually also originally known as the "Somogyi effect" - relating to diabetes and hyperglycemia in the AM.
@@jimdandy8996 that's insurin rebound hyperglyc
@@ellenorbjornsdottir1166 Uhh, what?
@@jimdandy8996 The somogyi effect is high blood sugar hypothesised to be a result of low blood sugar
@@ellenorbjornsdottir1166 Yes, I have heard of that.
Was the carnivore diet keto or mainly protein based? From what you ate I doubt it was fat based... More meat than fat it looks to me.... So could it be that protein is more hard to digest?
And an other question. Have u done the same experiment with completely KETO or SAD diet? So we could compare?
Question. Doesn't it make sense that your body doesn't actually need all of the lipids (fats) that you are eating, so your TG will be higher? On the carnivore diet you just don't have the time to use all of the fat you eat if you don't exercise. This makes sense to me. It is super interesting, but seems like common sense vs a new discovery.
So what's your point? You either have dangerously high TG or great TG depending on what time of day you test? What can you do with that?
The point is to fast for at least 12 hours before getting your blood drawn if any lipid testing is going to be done. Sadly, it seems that most doctors' office staff do not tell patients this anymore.
The reference ranges are set to a 12 hour minimum fast as that is how long it takes to clear them from the bloodstream to get to fasting level. I eat a high fat diet, so give it 14 hours.
How do you test triglycerides at home
Mine was 840... is that really worrisome? The results say ALERT. been hyper-carnivorous for a year. 95% carnivore with most of the cheats being outright junk food (donuts, icecream, twizzlers), but I was strict carnivore for 2 weeks besides 1 kiwi before getting my blood work. Fasted 13 hours as well.
Wondering how it would affect to have moderate volume exercise right after the last meal..
Which home tests are worth the cost? I’m seeing some at $100-$150 for strips plus device. Are these accurate?
No, they're made for diabetic sugar addicts with sky high values. If you're eating low carb you most likely have them around 50, in which case the device will just report "
Noradrenalone y is producing glucose witch then is transformere to triglyserides. S
why did your triglycerides go up when you ate just meat when people who are on a keto diet have their high tri's go low
Also, what was your baseline prior to this "test" and were you in ketosis prior to the "test"? Seems like Trigs at 221 at the beginning of the test tells us you were not in ketosis to start. Forgive me if you covered this in the video.
How are you checking your triglycerides so quickly? Do you have an at home cholesterol meter? If so, what is it?
He mentions cardiocheck.
I fasted 19.5 hours before a recent blood test and my triglycerides were 190. All my markers are fine besides that. No idea what to do at this point. I was zero carb up to that point for 4 solid months with absolutely NO cheating whatsoever. So discouraged. Concerned about my health I have two small boys 🙁
gangelo ... similarly, I been low carb for couple years... high cholesterol, high LDL, high trigs... ratios are good, except tri/HDL could be lower... so, gotta lower trigs... not sure how- might have to drop all alcohol as that is the only cheat factor for me.
Jim Kewley I hope that works for you; i’ve given up alcohol, coffee, dairy, keto pseudo-sugars, pork, I’m not so sure what else to do LOL
@@jimkewley3790 same I read where coffee causes triglycerides on some on keto
Sorry about your fingers - do they ever get a chance to recover .??
I had no idea that TGs were so high after meals. I've had low TGs for a while, but now it appears that outside of fasting for 12 or more, they can be pretty high. What does this info mean for those who might not have as high HDLs as we would like? My ratio is pretty good on my fasting lipid tests, but is that misleading?
Mine were high after a fasting test. I was shocked. Also HDL lower all since starting keto . I had high LDL and expected that . I was scared to see this .
@@debbietaylor20 same..tho triglycerides come down from 5.1 to 3.i was expecting better as not had carbs or sugar for months on keto.hdl only gone up .01 and LDL tripled.worried
Dave, what were your daily calories on this experiment? Are you possibly going above your maintenance level?
Dave, what meter do you use and or recommend?
I may be assuming but I did hear him say cardio check.
Is there anything to be said about optimal dinner time?
Informative and interesting. hypothesis.
What do you use for a home triglyceride test?
So we know now that we can make our doctors happier if we come late for blood testing.Thank you for stating that there is another useless blood test - triglycerides. What's left that is still reliable and really important? I guess it's HbA1c and CAC. And maybe insulin too.
A1c ...look at chriskesser.com and see almost 300 comments of A1c out of line.
Thyroid readings also fluctuate heavily, there are even books about this.
Insulin will be the same, look at the wide reference range
Haha...just give it your best shot, pray, and play 👍
I found this video to find out why my triglyceride was measured 198 after like 10hour fasting (and that's when I did my blood test for the regular health check) so I could assume I shouldn't worry about the high index when my HDL abit lower and LDL in a normal range. Hope to hear some feedback from anyone. Thanks
I've been doing keto six weeks and had blood tests and was shocked to see tryglicerades rise and HDL lower. LDL was much higher but I expected that as heard this happens . I was freaked out . My total cholesterol rose to 374 I'm in UK so think I converted it right . I've always had high cholesterol and started keto to lower it as don't need to lose weight but did lose 12 pounds .
What if you don't sleep at all?
I'm always radiating heat when I wake up in the morning, regardless of what I ate the day before. It diminishes to normal levels after a couple of hours awake. Is this elevation of triglycerides in the morning a reasonable explanation for the thermogenesis my body goes through?
Could be. The energy must escape somehow, if not through some other metabolic processes that don't involve losing some energy to heat.
How do you test your triglycerides at home??
So (dietarily) what is the fastest and most effective way to lower your serum triglycerides?
high fat diet and a 14h fast
AWESOME THANKS.
So Dawn Phenomenon but for fat-based energy instead of glucose?
No. It's fasting time.
(watch the video until the end 🙂)
Yes, makes sense!
So is it something to be concerned about or a phenomenon
Thank you 😊
How are you taking all these triglycerides test at home? Device, product, info?
I been carnivore 2 months and just has test. Everything was horrible. Inflammation through the roof. Triglycerides through the roof. Vitamin D less than 30. HDL less than 35. How is this even possible? Been keto before going carnivore
How much sun are you getting. Seems way too little
Ok, I got bored listening to the data. Can someone please summarise what the data tells us? Thanks.
I have tried the carnivore diet for 30 days after already in keto for 2.5 years. after 3 weeks of pure carnivore I went to get a blood work, my TG was 192! double what I had on keto, and the ratio TG/HDL were 3.2 also double then on keto. I had the test 11.5 hours after last meal. could it be that high because I didn't waited another 30 minutes?
Same with me and HDL went down. LDL very high. Only doing keto six weeks.
In Australia recommend 10-12hour test no.longer
