- Many people have been told by their doctor that they don't need to fast before their bloodwork. Nothing could be more False! Many routine blood tests give false results if you're not fasting when the blood is drawn. Don't fall for this lie that many doctors tell. Always fast from 12-14 hours before your blood is drawn for lab tests! I cover the most common lab tests that won't be accurate if you're not fasting in this video...

I once had chicken wings and potatoes, everything baked, 12 hours before labwork. Insulin crazy - doc said because of wings. Then I did it again, once with just potatoes, one with just wings, both 12 hours prior. Insulin skyrocketing again after potatoes, and no insulin raise when just wings. It's crazy how fatty meats are demonized these days. I will literally never stop eating meat until the end of my life.
I know, they totally speak out of sheer ignorance!
Because of the no carb portion!?
Cool experiment!
@paolamolinari364 it might not be sheer ignorance as much as inexperience. When I started as an FNP 14 years ago, I was repeating the same lies... that is until I got a few years of practice under my belt, truly looked into the studies and started to question the science. Since then I'll never recommend much of the BS they claim as "science" until I get a good look at it, read the articles, and observe for a few years.
Am I misremembering or did one of the low carb researchers note that triglycerides tend to rise again after 12 hours?
As a clinical laboratory scientist, Dr Ken Berry is absolutely correct.
Thank you
Another CLS here. Doing my own lipids after going carnivore I can attest that it makes a HUGE difference if your not fasting!! If your on a carnivore life style you should be fasting AT LEAST 12 hours, 16 is even better!
@@scottsellers9039 Ok perhaps one of you can enlighten us a bit here... Other doctors, I don't recall who atm, have stated that levels can vary so much that the difference between fasted and unfasted is less important than follow-up tests for variance week-to-week and so on... which makes the steps of the process perhaps different for the psychology aspect of adhering to fasting etc. in follow-ups? Anyway that's not a question you can answer but where I believe their opinions lead.
So the question, really, is whether or not it's true that both fasted and unfasted numbers fluctuate significantly enough that focus should be on more testing, rather than immediate manipulation of variables?
I am sure those doctors were not the types to suggest that the first high unfasted LDL result, for example, lead to immediate statin prescription. I think many here as well as Dr. Berry are concerned that some doctors are doing this. I don't want concern for these bad practices to get in the way of the actual scientific answers.
@@scottsellers9039I agree!
My husband is soon to be 70 years old. His blood sugar was over 200. I eat totally different so I'd had enough!🤣 I took all carbs sugar fruit and processed foods out of his diet and fed him grass fed beefs bacon eggs butter very low carb vegetables extra virgin olive oil flax seeds chia seeds and other seeds and nuts as well as organic no carb no sugar smoothies. He dropped over 20 lbs and blood sugar is at 109 in 60 days-
👏👏👏 Amazing!!
Absolutely. Same.
Take the nuts and seeds out next.
I tried this with my hubby, very slowly. After 4 weeks without potatoes he wanted to know why the heck we had no potatoes in the house. He was not happy. He still believes potatos and salads are the best way to lose weight even though he's still gaining and I've lost 60 lbs.
😮@@leaannebrummett9159
I had labs done without fasting because doctor said no need.. came back that i had stage 3 kidney disease. Had them redone. Couldn't get into labs until afternoon. Fasting for 24 hours. Everything perfectly normal!
I have stage 3 CKD and border line A1C. I 8:24 have been taking a supplement called Berberine. One tablespoon extra virgin olive oil twice a day. And 5,000 mg methyl B12 and vitamin D 2,000mcg every day. Plus low carbs and no sugar. I go for my blood work May 8th .
I'm an old doc and i was taught all this. Where have we gone wrong with medical education?
Big Pharma know exactly which "numbers" are needed by lab results, to get the doctors to inform their patients what meds to take.
They are the ones who define what parameters the results have to be in.
No one else could determine what the numbers need to be, to be "within range", or "Low - Normal -High".
During the creation of the thousands of meds out there, only the ones who do the development and testing know the truth.
So when the same companies do both, (develop the drugs AND the determination of the ranges set for the lab results), they are the only ones that have the supposedly correct info to give the labs and doctors to follow.
They would also be the ones informing the doctors whether the patient needs to fast before a lab test, and for how long.
So it is their (Big Pharms's) best interest to set it all up so that the most people fall into the unhealthy range as much as possible.
Then the doctors are required to suggest those drugs to patients as their saving grace to lower or raise the numbers some months down-the-road AFTER taking their new prescription all that time.
To be fair, Doctors have to follow guidelines of the organization they belong to, or to meet criteria of the hospital or clinic the work for, or insurance the patient has.
So there is a paper trail and if the doctor has the lab results and it shows you have some tests with the "numbers" pointing to a condition that requires drug intervention, and they don't follow-through and prescribe treatment, they could get in trouble.
That's why many patients get dropped by their doctor if they refuse to take prescribed (big money-making) meds like for statins, depression, anxiety, etc.
Those meds make Big Pharma BILLIONS fer drug per year.
Corporate medicine is destroying medicine at every level. No one trust it any longer. Big pharma medicine for everything. Don’t cure it, medicate it. Profits, not people. Beyond sad…
Had recent bloodwork check in UK - annual review. Blood pressure excellent, LDL just within range. Triglycerides to HDL ratio 0.65. Slim. fit and healthy - have never needed to go to the doctor, my record is blank. Got a print out of results and recommendations, by email. "You might benefit by taking a statin!" Dietary advice was the Eatwell guide - heavily carb based , cut down on red meat, Just a joke - I look at the overweight nurse reading from a script - she says do you do any walking - I say no, I run 25 to 30 miles every week. Oh she says, you should try to do more walking. When she asked how much alcohol I consumed I said I try to drink less than my doctor.
🤣🤣🤣
There are stupid people in all walks of life
Yep - this how truly crazy it all is.
I am a medic in the UK and I cringe at the nonsense that goes on here. I feel pain because I realise that if I didn't develop diabetes, I may never have known what I know now. The ignorance amongst doctors, nurses, and patients, is criminal. I know this sounds harsh, but my sentiments dicate the depth of the problem.
😂😂👍👍
This is so funny because I just went to the doctor for my physical and my lab work this morning. The doctor told me there’s no need to fast anymore. I have been fasting. I didn’t think it was right that you didn’t have to fast. It seems to me like it would affect a lot of stuff. Thanks for this video Dr. Barry. You proved me right🙋🏼♀️💕
They want your labs messed up so they can falsely medicate you.
Been listening to Doctor Barry and using common sense, figured out that they don't want you to fast anymore because it'll drive your numbers up. Then they can insist that you go on some sort of medication to bring it is that's elevated down. Not fasting and redoing the labs will show the numbers are still up and you need to stay on this medication forever. It's all about their bottom line. $$$
Fasting is racist now. lol!
They are saying no need to wear the protective apron at the dentist when you get xrays done now... healthcare is legit trying to mess us up at this point. It's nonsense.
They can put you on more medication if your labs are off-which they will be if you don’t fast beforehand.
I’ve heard that pharmaceutical companies donate a lot of $ to medical colleges.
🤔I wonder why?
I recently had blood work done. I walked away with a clean bill of health. The Dr actually said I had a boring health chart..no issues!! I've been a carnivore since the end of January. 🤸🤸
I am a BMT (Biomedical technologist) and specialised in biological chemistry.
I always gets suspicious when a doctor neglect the fact that Testosterone tests and some other hormon tests needs to be done 7-10 am and fasting.
You might want to know what those levels are in the middle of the day instead of at peak output
My mom in her lat 70s told me her cholesterol was high, no issues in the past. I said what did you eat the night before? How long did you fast...her reply, I didn't. I was like, go retake the test.....
I started the carnivore Diet because of you because I needed to do something to get this weight off so jan1st was 460.4LBS and as of today 2/13/24 I'm down to 420.1LBS just wanted to say thank you for all the advice I've learned and still learning
Tremendous. Well done and keep up the good work, your body will thank you. Maybe you'll have to soon change your name to smallkntry6251 😉🙏👍
You are knocking it out of the park!
Love yourself 💙walk💙stretch💙nap💙 how wonderful you are changing your life 💙
Keep up the good work!!😊
Fasting KETO and OMAD did wonders for me. I started walking for an hour after my meal and the benefits were eye opening! Keep it up. Cheers.
@@stuartgregory6848 what is OMAD?
So many people come.for labs unaware. Docs aren't telling patients to fast. It's amazing
Right before she went on maternity leave, my PCP said she wanted yearly labs and I should fast before the draw. I put it off and didn't get the labs done, but 3 months later another doc in same center sent me for a specific blood test for something he saw me for. I didn't know it, but the lab also drew blood for the order that my PCP had put in earlier. Then her MA sends me a message and says my cholesterol is high and the new temporary doc wants me on statins. I just wanted to write back, "tell the doc to go piss into a strong, oncoming wind."
Same here! I made them look at ALL the numbers, and the doctor backed down.
@@jillmcclintock1717 good for you!
Thank you, for the chuckle 😂
My sister, who is a 40 year+ nurse, tells me when she has her Labs done "no one told me I needed to Fast." I was floored. She is tired of me telling her of the importance of an LCHF type lifestyle.
I'm a nurse, you can tell me anytime!
I understand your frustrations, I have the same problems, I hardly say anything unless I'm asked.😊
I’m a nurse too. We are some of the sickest folks and we take care of sick folks. Carnivore is the best thing I’ve done. Nurses should be leading the way….
At my local hospital which has excellent care... But some (a lot) of the nurses are dreadfully overweight. It's definitely not a good look.. My keto and now low carb + IF life is thought a joke by many. And always pushing the carbs on me... Plus the *you're too skinny*
I wonder how it would go down if I replied *you're too fat*.
Whenever I see a fat nurse I cringe. And it's very commen
Thanks. Going to the doctor tomorrow at 1pm. I will be fasted. This is bullshit she always tells me I don't need to be fasted and my LDL runs at 241. She wants me on statins. Even said to me last time why should we check for things if you won't take the medicine for it! Im about done with her.
Doctor$ make $$$$$ pre$cribing brands of big pharma.
Dr, Berry, I just left my long time doctor because of her lab technician. She has a God complex where she thinks she is right on everything because she draws blood. I kept telling her I only have done fasting blood tests because if I eat it messes up my readings. She yelled at me in front of the whole office , saying , “you don’t have to be fasting for these three tests. My doctor is the one who orders fasting labs. As I walked out the door of the backwoods thinking lab tech yelling, I said, “I’m done”.And I never looked back. That’s when I came online and found you! You have done more for me in two months than my doctor of 15 years has. Blessings can be found if you look for them. Thank you from my heart for being here for those of us that were about to give up. I’m now detoxed off all grains, almost done with sugar, as I still have one teaspoon in my morning cup of coffee. I love eating carnivore, I feel so much better, and I am finally losing weight. I am almost 67, and a great grandma. ❤
I wanted a full Thyroid Panel done. I got TSH, Ft3 & Ft4. That's it. No antibodies, no Reverse T3. My Dr. Insisted they did a full panel. Plus, I forgot to withhold Biotin and she also told me that wouldn't make a difference. It stated right on the bloodwork panel that taking Biotin would skew the results. Pretty sad when you know more than the Primary. She told me my weight gain and fatigue was due to my age & hormones.
Biotin supplements can affect a lot of test results. Many people are unaware of this. Glad you are.
Not sure if you’ve seen Dr. B’s videos on STOP THE THYROID MADNESS website and book as a resource but it truly saved my life. They have great resources on the website to get your own testing as well.
Did you kick your doctor in the stethoscope?
@@AllegedlyApril😂😂😂
@@AllegedlyApril She's not even a doctor, just a NP. Of course she had to push me to go on statins. I declined. I told her I wasn't worried about my cholesterol. My Tri/Hdl ratio is 1.25 and anything under 2 or 1.5 is good. She didn't even know what I was talking about. A real idiot!
I have not had good experiences with doctors or doctors offices. They don't listen to me and they try to give me prescriptions that i dont need. If I took all the crap that they wanted to prescribe to me over the years i would be dead. I sure wished I could find a doctor that I felt comfortable talking to. There is a pharmacist in my area who is very knowledgeable and explains alot to me if I have questions. I don't take meds but it does concern me when doctors try and get you to take meds you don't need. Going in for just a check up is sooo stressful for me. I havent been to a doctor in 4 years because I don't know who to go to.
I say this respectfully...if you eat right, and feel good, avoid doctors at all cost. They are not what they used to be.
I have the same problem every different medical professional I go to trys to change and add to my medications. I had good numbers untill all the experimenting
I've always fasted before all blood tests.
Husband just had labs.....cbc, cmet, lipids, glucose, a1c, psa and tsh.....he ate huge carnivore breakfast just 2 hours before his appt with doc and she had him get blood drawn during that visit. After stating concerns about him not fasting she said it was fine not to fast.....this was two weeks ago. All his cholesterol numbers were off...highest he's ever had. She also tried to put him on a new med for triglycerides and he refused to pick up the meds until he got the labs redrawn with fasting. he is getting them redrawn. I will not be surprised if his levels come back "normal".
@AnnaSusannaFinkelstein-bd7ul I don't know if the doctors are even aware of it though. I think this is simply how they are trained and educated. The pharmaceutical and insurance companies fund most of the medical academia, and Pepsico and General Mills fund most of the nutritional academia. At the lowest levels of education, children are being taught that their parents are liars, the USA is evil, and their gender is a social construct; at the highest levels of academia, they are taught only how to ensure more people end up dependent on medicine and doctors forever.
Wow, I didn't know they have triglyceride med
@brendahunter9134 new to me also. I wish asked the name of it. The pharmacist said it was specifically for triglycerides.
Fun story. I've known the world of fasting and keto for decades. My habit for breakfast was dandelion tea with butter and cream to mimic coffee; sort of fat fast to extend my low insulin as long as possible. When I went to my new doc last year I wasn't thinking clearly and I drank my usual "coffee" on the way to lab work. My lab readings were mostly fine, except ta-da triglycerides. As a testament to my new doc, she didn't flip out but said we should work on that. I was upset by that number and went on a search about it. To my surprise and shame, fat right before lab work jacks up your triglycerides. LOL We both had a laugh the next time I saw her and my triglycerides had dropped almost 100 points. When I told her what I had done and what I had learned she told me I am a rare patient that on their own goes searching for answers and does something about it. I love visiting her, she's the best.
Do you know how discouraging it is to have an endocrinologist that has you have all kinds of lab work the lipid panel, the thyroid and no instructions about fasting… Dr. Berry I’m glad that I’ve listened to you in the past. I’m thankful that I have enough sense the fast before blood test. I’ve been eating the proper human diet and I can almost go all day. I can go all day without eating and actually feel pretty good.
Wow. I must be lucky. I've never had a doctor tell me not to fast before lab work.
Yes same for me! My Doctor always told me to fast for 12 hours. Always.. 😉
Hold on to that doc
@@GoldenNugget.
My doctor has always told me to fast for 12 hours but only last month he said that I don't have to fast any longer so it's a recent thing!
@wonderwoman6232,
My doctor has always told me to fast for 12 hours but only last month he said that I don't have to fast any longer so it's a recent thing!
Watched one of your videos 11-30-19, started keto 12-01-19. Asked the NP for an HbA1c and a CAC 07-15-21. These were refused. A CBC and a comprehensive metabolic panel were done instead. In December of 2020 my chart indicated that l received smoking cessation education. I am a non-smoker. This was finally corrected 09-02-21. I no longer go for medical care.
Just find a good doctor instead of giving up medical care.
Nurse went to draw my bloods but refused because I had fasted. I think it maybe to give incorrect readings so can therefore prescribe more meds. Went away had some food got tests done and yeah high readings I didnt get scripts filled just carried on.Havent been back to drs since.
Yeah that was my thinking as well! So they can write some more prescriptions and get those kickbacks from the pharmaceutical companies…
I think you're right... they get kickbacks for their Rx writing. Docs these days are just the distribution arm of Big Pharma.
I've been told once in recent years that I didn't need to fast for blood labs. But, I've been getting labs for a long time, and I always fasted, and that is what I will continue to do.
And I always try to schedule my lab appointments first thing in the morning, so I don't end up fasting too long.
If I fast before blood work i'm going to pass out on the floor
I get a yearly check up every year with bloodwork done and the doctor never told me to get it done fasted. Last year the lab tech looked at me and said did you fast? I told them I didn’t know I needed to fast and they just shook their head.
The Veterans Administration Clinic I go to has now stated that fasting isn't necessary for routine yearly lab work. The lab tech told me now the doctors just order an A1C, they don't seem to realize the rest of this information you have stated. If the doctors can't realize the information, you just stated, it makes one wonder how well they can diagnose any issue. I already know, having been going to these clinics for some time.C
@@AnnaSusannaFinkelstein-bd7ulExactly. And they really hate when you ask questions, especially the VA doctors.
Everything is a complete mass out there, but there are true professionals
I am currently going to a Physician who has never asked me to 'fast' before any lab work. I asked the office staff about fasting before blood is drawn. They told me that fasting does not affect the results. And they want to start me on a statin. I am looking for another Physician.
Kinda sounds like they want the results distorted so they can prescribe you something, doesn't it?
@@kathysmathers512 I agree.
Absolutely, not fasting really affects your triglyceride readings and your full lipid panel for sure.
Fasting is IMO essential for lipid tests but fasting too long is probably not a good idea.
I turned a lady onto your site today at a service station. She seemed very interested in Carnivore for weight loss and some situations she had going on metabolically. I hope see looks you up!!
Thanks so much for caring so much to post these health benefits!!
I'm surprised there s no mention here that you shouldn't fast too long either ... it's literally 12-14 hrs. No more, no less.
1:48
I assume 12 hrs is the minimal and 14 hrs would be optimal. I don't think fasting 16 hrs would make your test results incorrect.
Yes, you hear that (fasting not necessary) more often now…my wife and I are of a certain age and both RNs…Fast for labs people.
Ps. Make it a “fun thing” by having your favorite food after.
Exactly what I do!
I have often said that fasting is not some weird break from your regular pattern of eating. Instead, fasting is your normal resting metabolic state and eating creates a brief period of crisis while your body deals with the assault of all that food. You shouldn't think of it as though you have to schedule a fast for your tests. Just postpone your eating until they are done. Of course you would take your blood tests when your body is in its normal resting state and not when it is dealing with the temporary feeding-related crisis.
I am so glad I found this. I've had my labs done every 3 months for about 3 years due to B12, D3, Iron, and Ferritin deficiency, and to check A1C and autoimmune blood work. I've never once been told to fast for anything. I still feel like some of my numbers aren't accurate due to some lingering symptoms. I really wish I were your patient.
Now you know, and maybe your tests will be more accurate next time after you’ve fasted for them. 🙏
You can also not fast for the iron panel if you supplement iron about 2 hrs prior, then you can see how effective your supplementing is by looking at the tsat%. This is so you don't take too much iron, safety reasons.
blood iron test only report blood iron levels not body level. unless you lost lots of blood 99% of ppl have too much iron and need no give blood not plasma, only way to reduce iron overload and take copper. read the book CUre your fatigue.@@therealjenniferrr
my left ear approves this message
I thought my headphones were messed up, thanks for commenting 😂
LOL!
SteveEricJordan wins UA-cam comment of the day 😂.
My right ear doesn't work, not even a tiny bit, so I'm cool.👂🏻😅
Correct 😂
My doctor tried to pronounce me as diabetic based on my non-fasting glucose test, even though my A1C was 5.2 and then 4.7. 🙄 I had no idea she was going to run labs on me (she was a brand new doctor to me). I spent 2023 making sure she didn't sneak that diagnosis on my chart. I do have peripheral neuropathy, but that was brought on by chemotherapy almost 15 years ago. NOT diabetes.
@@AnnaSusannaFinkelstein-bd7ul Thanks! These automatic features aren't always our friend.
I have always fasted before blood tests. I did not even sure why, it just seemed like the right thing to do. And now that I don't eat breakfast anyway it's very easy I just get my blood test done in the morning sometime.
I always fast but no more than 10 hours when I was still on the SAD.
I will up that to 14 hours now that I have been low carb/ low sugar for two years.
Thanks Dr Berry!
My doctor and suggested I get lab work done immediately and asked if I was fasted. I said I wasn’t fasted in that I just consumed a 1 pound bag of M&Ms. My triglycerides we’re close to 500. 😐 I have since given up sugar, fiber, processed foods and I only drink my carbs.
For the last 6 months, I ate 4 over easy eggs with fatty meat for breakfast (6 strips of bacon or two sausage patties, steak, or pork chops). I averaged this at least 6 days per week and the random off day I skipped breakfast entirely. I got my bloodwork done last week, and my LDL went from 105 mg/dL to 94 mg/dL and my HDL went from 46 mg/dL to 79 mg/dL. This was comparing February 2023 bloodwork to the recent February 2024 bloodwork. Keto did not skyrocket my LDL like I thought it would, but instead it decreased. My triglycerides went from 66 mg/dL to 63 mg/dL, so a very slight decrease. I am very lean, 5'7" 125 lbs. and fortunately didn't fall into the Lean Mass Hyper-Responder phenotype where LDL skyrockets on a very low carbohydrate ketogenic diet.
I my country the referral for the tests has instructions written on the buttom, including how long to fast. It's automatic. Then the technicians ask if you've fasted before taking the samples.
I once didn’t fast for a full blood panel because I didn’t know I was supposed to. I rarely went to doctor and never got tested before. When he read the tests anyway… he said my numbers were good anyway and that I must be one of those people that’s never going to have to worry. I haven’t bothered testing since and now I’m full carnivore. I just ate normal sad before.
The only lab I have been getting is for Testosterone Level, and I always fast. But not like 12 hours before but 48 hours before, and I do this because this would be a state I always strive for anyway. I find when I am fasting, I feel better; eating for me, even in Keto or Carnivore, can result in a lot of pain, so I do it sparingly.
But I am in Canada, and it became pretty apparent that Canadian Medical does not buy the best instruments; I found this with my testosterone tests, which they do calculations and do not actually know all the components. It was suggested I go to the US and buy a Testosterone test at an independent lab actually to find my testosterone levels. Still, my doctors both strongly opposed me learning the actual values. I always think in Canada, the medical system isn't about making you well but fattening their own pockets, getting paid to promote suffering.
My mother had a fluids test done years ago, and the number that was returned to the doctor indicated she would only live for 6 weeks, so we all flew in to sit with her at the bedside under the understanding she was dying. As it turned out, a second test was ordered, and the previous test number was out by a decimal point; someone had written down the value wrong prior to entering it into the computer. This is just how archaic the Canadian "Free" health care system is that is paid through your taxes.
I'm in canada. Never experienced anything like you have.
Definition of fasting before blood work...only plain water. Influencers confuse people when they say things like "I did an egg fast" or "cream in your coffee won't break your fast". Confuses the meaning of true medical fasting.
Normal reference ranges are based on the fasting state.
Go to a separate outside lab for blood tests if possible instead of being drawn in a Dr office where the specimen handling might be poor.
Only last month, my doctor said to me, you don't have to fast to get your blood work drawn any longer; that's a thing of the past! I said ok doc. I ignored him and fasted as usual for 13 hours.
I went out of my way to get blood test while fasting, to get baseline, just in case.
good to know that's actually how it's Meant to be done.
keto and fasting community Win
So now that doctors do require fasting the results are going to further skew the “normal” range for everyone. Of course they don’t ever share optimal range like you do in your common sense labs book. Thank you for this video!
I follow up labs from other docs and lately have been receiving a flurry of raised lipids results. On questioning most of the patients I have discovered a large proprtion of them were not fasted. Have had to apologise to the patient and advise them that the results are inaccurate and will need to be repeated in a 12 hour fasting state (water only). Have followed this up with stern letters to the doctors involved. In a good few of these results a recommedation for statin has been made - which makes me wonder how many prescriptions are being given based on false data.
What's up with the muted sound on this? Will read captions. Can usually hear you very well on this cheap android phone.❤
I'm so glad I'm a life long learner, my triglycerides have been high and my doctor said if they don't come down then he's prescribing a statin, and the last few tests have not been fasted. So while I am working on changing my diet, I am gonna make sure I am fasted.
That’s great that you’re working on getting your triglycerides down. When I think of high triglycerides, I think of high sugar and refined carbs. Good luck!!
@@crh251 yes! My doctor never mentioned it and I've been complaining my bs have been off for years! It was well you can have a year or statins. So frustrated with the healthcare system. While I'm grateful for everything I'm learning, as much as I pay for issueance, I shouldn't have to go to UA-cam doctors to find this out.
@@Romans12.2, exactly! I know how you feel. We learn more on UA-cam and educating ourselves than going to doctors who’ve had years of schooling where medical schools only push drugs. I will refuse to go on a statin too if my doctor ever recommends it. There are definitely other ways.
I listen to the sound through my hearing aids, and you have no right channel on this video.
Well crap.. here I was thinking, after reading the title, my doctors have always said to fast before labs.. I was hoping that was wrong. ~sulk~
Me too!😕
I an so sick of my doctors, they insisted on doing my labs in a non-fasted state, and my numbers were so different from last years, I was so upset, now I know why and I will INSIST on fasting next time !
@tinabeckett2607,
It seems like not fasting is a recent thing because I've always fasted for 13 hours before I get my blood drawn.
Only last month my doctor told me that I didn't have to fast any longer as it's a thing of the past!
I didn't listen to him and fasted as usual for 13 hours.
I have never been told I didn't need to fast. The doctor will tell me she needs blood drawn, but did I fast that morning. And if I ate anything, I have to come in on another day when I didn't eat anything.
I have always fasted for all blood work and will continue too!
My doctor has always told me to fast 12 to 14 hours before blood draw. So glad I am doing it right. Thanks Dr. Ken.
I always thought it was weird that doctors would say you don't have to fast. I will always fast at least 12 hours. Thanks Dr. Berry for bringing this up! I think its really important for people to know.
Why does UA-cam always run a Burger King add before your vids? LMAO!
They don't for me, perhaps it's telling you something about your eating habits 😀
I usually get the Ozempic ones.
I get Stuck Poop, Imma Gonna Jump in this Pool, and the buff lady who has a pizza delivered.😂
you gotta get a youtube ad blocker! Or just pay premium youtube so you don't get those pesky ads
@@cleancutguy1892 You tube has changed the way they do ads. For now you can refresh or skip, but they have said they will end that. They also throttle those with blockers, making live shows almost impossible to watch sometimes. All basic stuff out there...I do SEO, so I'm om top of it.
Each video I watch of Dr. Berry's makes me realize how much I have been lied to! Thank you for telling the truth, Dr. Berry!
I did the fasting from 10 pm to 10 am, but my glucose was 100~113 . I bought a glucometer and started checking to discover this strange dawn phenomenon! My glucose before dinner is always
Thanks Dr.Berry I appreciate the information.
My Wife is a Nurse Practitioner, FMP.
I am going to share this with her.
Have a great day.
OH, I've had several of the listed panels taken, AFTER eating, because I was told to "go ahead, its fine"
honestly I'm surprised she still says to fast for glucose and lipid
Thank you so much. I will fast before any blood draw and not a problem because I rarely eat before 3pm anyway.
My theory is when lab being drawn FAST
You just saved me a big problem. Almost had my labs drawn by a new physician, but I didn’t let them,( long story) I’ll be fasting before the next appointment.
Aha! I just got a sheet for blood work and was surprised it didn’t indicate to fast. Thought I might anyway. Thank you!
Thx for doing this, filming it and sharing it with us. 👍👍👍👍👍
Thank you Dr.Berry for sharing with us.
Another great video, thanks doc.
Thanks for the review. I totally agree with your assessment
Very useful Information 👌 👍 👏
Thanks for sharing this vital information, Dr Berry.
Thank you Dr Berry
Very very informative
I fasted for at least 18 hours before my last blood tests around September 2023. The results were very favourable indeed. From now on I will always fast before I get any lab work done. So glad to hear Ken confirming that fasting before lab tests is a good thing. I will not get any lab tests in future without fasting. In fact I’m seriously thinking about a full 24 hour fast the next they post me out an appointment letter to come for blood tests. I’m wondering though, how would a 3 day fast work out before getting these labs done? Could be interesting and I most certainly wouldn’t rule that out either.
Dr Berry says 12 to 14 hours. No shorter or longer and actually either direction could skew your results.
Hey Dr. Barry please check your settings when you upload your video because there’s only sound in the left side
I went to have blood drawn mid afternoon (This was about 10 years ago) and the phlebotomist refused to believe i was fasting, insisting I told her when i last ate - which was over 48 hours prior, she then didnt want to do it because i had fasted for too long! After checking with her supervisor and putting extra notes on my file they finally agreed.
Bizarre. I have never had a physician not tell me to fast for lab work, especially for glucose, A1C, and lipid profile.
Good info
OK!!! I will do this. Blood panels are due ASAP for me.
I got labs done midday after a dentist appt. I was starving & numb from getting a tooth prepped for a crown..got a protein shake on the way to docs office & took a couple of slurps before I went it. Told tech I'd eaten breakfast, forgot to mention the shake slurps. Doc calls me all freaked out about my A1C, wants me to come right back for more labs. I'm in Alaska & over 60 miles from his office. I knew why my number was high & told them I'd be in next time I went to "town", he was a little mad. Stopped by 2 weeks later, had eaten breakfast, A1C was "normal". I'm going to a different doctors office now...making a list of all the tests I want done so I'll have a baseline before going Keto/Carnivore. Don't think I've had fasting blood work done in several years.
I had my regular 6-month bloodwork done last month. I had eaten about 10 hrs. before- late night snack after work of PB Pretzel bites and a dark beer. All my numbers were good except my LDL was 171?! Anything in particular that could have affected this? I have cut a lot of carbs out of my diet, and I have been burning off some fat. I've lost 10 lbs, mostly fat, in the last month or two. My LDL has never been that high! I'm not on any statins right now, but my doctor recommended I try two low-dose statins for 90 days and we'll re-test. I made sure to ask for the detailed cholesterol report! I had asked for that for this last test, but that's not what I got. 60 yrs. old, 5'10", 165lbs.
My PA never says I have to be fasting, but the lab always asks have you fasted for at least 12 hours. I am like yeah I only eat once per day in the evenings normally. They look like they don't believe me, but they draw my blood anyways.
Thanks for bringing this up! I can't tell you how many times patients are treated on "false" results because patients and physicians are either ignoring, or are unaware of the way fasting affects lab results!
The VA in Jacksonville, Fl started this no fasting required in their blood tests. I still fast because I want an accurate reading.
Thanks for the 12 - 14 hours info, Dr. Berry. Some of my tests were marked fasting and some weren't. I'll do the 14 hours. ❤🇨🇦
They prescribed my son metForman because they lab tested him not fasted.
😞
My Dr. allay has me fast and a big thank you since been watching I have lost 25 lbs and lower my A1C 6.8 since September 2023
❤ thanks!! I fasted too long and had crazy labs a few months ago so redid last week, 12 hrs fasting.
TSH at 3.4 so gonna add daily minerals & check again in a month, already added armor. Only other lab problem was ldl 😅
Consider using a desiccated Bovine thyroid extract instead of the armor processed porcine versions with plastic and other random chemicals added.
Where can you get a true bovine extract with all the thyroid hormones?
@AveryMilieu do you know of or recommend one in particular?
For my last annual, my triglycerides were 600’s and HDL was 35! Doctor told me it was my diet. I went back for another issue and I told him I found out that you need to fast from Alcohol two days before b/w ! He snapped and said it’s what you’re eating also!
I gave up Alcohol and had blood work done again tri #170’s and HDL 45
And no I did not tell him yet!
listening to this on headphones, getting left audio only, am I the only one? 😅
Me too. 😅
Wow! This was good information. I've taken vitamins, had breakfast, and drank coffee then went to get many of the tests you mentioned. I will know better next time.
triglyceride and blood sugar are absolutely highly affected if you are not fasting, but cholesterol is not, I have done that many times
Great information. I had to lipase test not fasting. 1st one was 201, 2nd one was 183. Doctor said not to fast. I will fast for the next one.
no-one from my HMO has recommended fasting before taking my labs. I have been with this HMO since the early 80's .
no breakfast plus sleeping should give me about 12-14 hrs fasting. Thx for the tip.
Thanks doctor Berry.
Please speak to drinking black coffee prior to blood labs. I've been told by medical professionals both I need to avoid coffee and that drinking a couple cups before labs doesn't matter.
Please clear this up. How does drinking black coffee affect labs?
Great video, doctor. Is 12 to 14 hours the magic number? Do not go longer or shorter?
I just had labs done for life insurance and the insurance company told me to fast. But the Dr said that i didn't need to.
So, my husband has been struggling to keep his TSH levels in the normal since his aortic valve replacement surgery in February, 2022. His primary care is a NP (almost impossible to get appointments with a PCP nowadays) and keeps wanting him to come back every 8 weeks for TSH levels as she says he has hypothyroidism. This office doesn’t seem to be able to keep his TSH levels in the normal range. My husband is very irritated and doesn’t think he has hypothyroidism and I’m tending to agree after seeing this video. He has a history or elevated kidney and liver function as well as the aforementioned TSH problems. However, just about every time his blood has been drawn without fasting. Also, anytime they want fasting they say nothing to eat or drink after midnight and schedule labs for 8am. SMH…definitely not 12 - 14 hours fasting!
