    In this video, Dr. Berg talks about cholesterol spike on a ketogenic diet and intermittent fasting plan. The body makes 75% of cholesterol and only 25% of it comes from the diet. There is a huge feedback loop on how the body makes cholesterol and the cholesterol from the diet. In other words, when you eat more cholesterol foods, your body doesn’t make as much and when you don’t eat as much cholesterol foods, the body makes more.
    Two Purposes of Cholesterol
    1. For structural purposes - cholesterol is needed for every single cellular membrane in the body.
    2. It is needed to make vitamin D, bile and steroid hormones
    When you fast, the cholesterol will go up, you already tapped out your glycogen reserves, now you are tapping into the fat reserves. Fat has the major storage of triglycerides and it is the largest storage of free cholesterol.
    Remnant Cholesterol - It is what is left over from total cholesterol minus the HDL and LDL.
    • 17 or less: Optimum
    • 18 to 23: OKAY
    • 24 to 29: Concerning
    • 30 or greater: very concerning

    I have been IF one year and down 28 pounds. Yesterday's blood results doctor is more concerned about my Cholesterol number which is down almost 40 point in 6 months, but he feels is still to high and prescribed Statin. In doing your calculation my remnant cholesterol is 13. Thank you for this explanation!!

    Dear Dr. Berg, I did a 48h water fast, broke the fast for a day and then fasted 12h for a blood lipid profile (my mistake). Well, my TC and LDL had spiked 60% from a previous July profile. Am I to conclude that your logic as it pertains to Keto and IF, is also applicable to prolonged fasting? It would certainly seem so. I need your help as I expect my cardiologist, who is otherwise open minded, might be inclined to be less so now.

    Hi Doc!! Thanks for explaining so wwel. I have a question as to how long after IF started to be considered temporary? Will that always spike when in IF or will stop after few months. How one should wait i months for the next test. Does more fasting period keep it increasing. Pls answer

    I had fasted for 80hrs when I got tested. My ldl was alot higher than 2 months prior. Could it be because I was fasting??

    Dr. Berg - I'm a type 2 diabetic. My remnant cholesterol is 43. I know that's not good but I've been on a serious keto diet with IF for 4 months now. When I started on February 1st, my A1C was 10.9 with a fasting glucose of 240. Today, the lab results show that my A1C is 6.9 but as I expected, my lipid panel test results all went up resulting in a 43 remnant cholesterol following your formula. Should I continue my IF and keto? I've lost 15 lbs and completely quit all meds from day 1. That score kinda scares me a bit.

    What i understand is that this so called remnant cholesterol is the same as VLDL.

    Hi. I'm confused with a statement you made about fasting and taking a cholesterol test. When will I ever be able to take the test if I'm always fasting? I'm doing the 16:8 IF.

    My Dr just told me mine was high... total is 203: HDL- 73; LDL- 117 . Am I correct that my remnant is 13 ? Last year I was 174: 70/74 so it has gone up. She told me not to eat animal fat or butter 🤦‍♀️ I am 52 and very active. Bike, hike, run,...

    Thank you Dr. Berg! I’ve had these questions floating around my brain 🧠 for sometime. Been on a keto diet for 5months now only to find out my cholesterol level increased by 10points. It all makes sense now. I will figure out the calculations and see what I come up with 🤞

  • Ludwigvan

    My cholesterol was measured some time ago before a keto diet. If I subtract the HDL and LDL from the total I get zero (4-2-2)mmol/l. Triglicerides were 0.51mmol/l
    I don't know how they compare to these standards.

    Dave Feldman has tested this theory and found that his cholesterol ratio was lower when he loaded up on cholesterol prior to getting a blood test. Imo the pharmaceutical industry has created this blood test protocol of fasting prior to the blood test so as to skew your blood results which will result in being prescribed Statin drugs.

    Though on Keto and IF, my Remnant Cholesterol is 32, the LDL/HDL ratio also is pretty bad. Seems like I'm in trouble.
    And don't tell me I'm doing it wrong. No. I am doing it right.

    Thank you for this information. I have my first doctor appointment today after being on keto for nine weeks. I am down 26 pounds. I just figured out my remnant cholesterol, and it is 37. So naturally I’m very concerned. Can I expect this number to improve as I continue on keto? I am doing intermittent fasting also. Thank you for your very informative channel, I am learning so much!

    Cholesterol doesn't go up with an overnight fast. It takes about 12 hours to finish processing the cholesterol from the last meal. So if you eat dinner at 7PM, you should be good by 7AM to get your test. With that said, if you eat a very high cholesterol meal the night before it can take longer and give a false high test result.
    The cholesterol from fat burning doesn't go up until a person has used up their glycogen reserves and fat burning begins. That can take up to three days. IF can raise cholesterol because cholesterol will go up when a person maintains a calorie deficit (dieting to lose weight) and is burning fat.
    Incidentally, he's very right about cholesterol being cleared through the liver. This is why very low calorie diets are associated with gallstones. The body is releasing a lot of cholesterol and, with a fat deficient diet, the gallbladder doesn't get the stimulation to release the bile. This results in gallstones. A person needs at least one meal with sufficient fat to clear the gallbladder every day to prevent this. (If I recall correctly, I think it's about 15g in one meal)

      I did my last test on a 4 day fast, my colestherol was 300 with 259 LDL, crazy! I was always around 200 total. I intend to to the fasting for more 2 to 3 months and then check again

  • David Gill
    David Gill 8 months ago +1

    I wish you would explain this to my doctor. Despite all of my previously unhealthy numbers going down and normalizing including A1C and glucose and blood pressure high cholesterol is higher and that is because of the keto diet in the fasting state but my doctor seems to think I need cholesterol medication LOL

  • Lance Peters
    Lance Peters 8 months ago

    Just did my blood work after 65 days on Keto. My total in 2018 was 226 and now 205, my LDL was 123 now 141, my HDL was 36 now 40, my VLDL was 67 now 24 and my triglycerides were 336 and now 122. But I too fasted for over 16 hours prior to my test. My remnant number is 24 and concerning? All my numbers were much better with the exception to LDL, but if I hadn’t fasted maybe that number would be better also?

    The formula for remnant is a little misleading the way you drew it. Total minus HDL divided by LDL. I had to review the lecture. My last two tests came up exactly 28 remnant. Hopefully the next test will be lower?

      @Avacado and Greens well if we're going to assume them as healthier than Americans then i feel like it would be safe to have evidence of such before running off with that type of conjecture. Explain how my thinking is "extreme"

      @Chriz Roman oh I don't know, Japan and Italy don't do keto. Aren't they healthier than Americans in general? You're too extreme in your thinking. I'm done with this conversation. Good day.

      Avacado and Greens 8 months ago

      @Chriz Roman Not arguing, but there have been people who weren't ever on keto that are healthy also. It goes both ways. I do agree with you about the obesity issue. And what people do you know that have been on keto 30-40 years?
