Intro to Lipids & Lipoproteins: Why there is no ‘bad’ or ‘good’ cholesterol | Peter Attia, M.D.

My HDL is 103 and LDL is 157 my PCP says take a statin but my Cardiologist says not to. I’m so confused.

I had a stroke 2 weeks ago after 7 months on the Keto diet, and my total and non HDL levels are VERY high. (Never smoked, non-drinker, ideal weight, 63). What to do?

Curious on what you currently think about high HDL. My husband has had HDL over 100 for the past 10+ years. Most recently 127. We eat very healthy (plant-predominant), he exercises 6 days / week (cardio and weights), averages 3-4 alcoholic drinks per week. We have always been told "congratulations, your HDL is nice and high." However, we have read the recent studies on the U-shaped curve, hypothesizing that risk goes up with very high HDL. We are trying to determine if there are situations where very high HDL is indeed a good thing, or if this is something we need to dive deeper into.

I can’t wait for your next upload!

The main question is, why do Lipoproteins only harm arteries but no veins??? Stay critical. Think for yourself! Think of pressure and think of harmed arteries…… conclusions???….

Cholesterol to high said the family doctor. 319. Please let me know if this is to high!!!

Just like BMI I think Cholesterol levels apply to the population in general and are not valid for all situations . At 55 years old my recent blood numbers show HDL 1.69 TRi .74, but an LDL of 3.75 . I laughed when it was suggested I make "lifestyle changes". I do 6 hours of zone 2 per week (6 X 1hr Incline treadmill walking) 2 4x4 Vo2 max sessions on my Concept 2 rower per week (Garmin predicts VO2 Max of 48) plus 2 to 3 weight sessions. My diet is literally as close to ideal as humanly possible (almost nothing to tweak) to the point where I switched from french press to a paper filtered coffee maker to reduce the fat in the unfiltered coffee to see if that would affect it (I drink about 5 cups a day). There is nothing I could change from a lifestyle perspective. I would be very shocked if I had anything other than pristine clean arteries yet my "3.75" puts me into the high category.

Mark here, NOT Elke. I have only recently discovered the ill effects of the following... Overall there are many additives that are more directly responsible for the plaque forming & the downgrade in overall health & specifically in the blood vessels. Certain ones which are banned in the EU such as titanium dioxide particularly nanoparticles(TD2np) which pass through the blood brain barrier & into cells individually clogging the cells keeping the cell activity of it"s mitochondria from functioning being sluggish, not therefore bringing IN nutrition nor taking out the toxins. This is used as a colorant both in more & more foods & in supplements & meds as white & in clear coatings or as a whitener to alter the colors. The production of these NP's has also skyrocketed to a massive amount so that the addition of such in the water supply would be virtually undetectable by sight as the particles are too small to be seen by the naked eye.
mall It is put into milk products to produce these whitening results for visual appeal, even used in powdered sugar products. This TD2 is that which is used in paint to produce ultra white paint & in primers sticking super well even to glass. Therefore leading to sticking to blood vessels worse than cholesterol needing to be eliminated by metal detoxing asap. It will also fill in defects in blood vessels making them more subject to further deterioration with internal bleeding & disrepair apparent in easy bruising first noticeable on the skin surfaces . In experiments in mice a slow accumulation of such led to a deterioration of health with crippling effects & even death. End thought is that things are weaponized needing to be studied, which some such studies are now or should be now still available as they once were, mainly of oriental origin(I think Japanese). Thank you for considering these things & expanding on them. Thank you for blowing the trumpet concerning this.

My cardiologist wants to give me meds to reduce my ldl cholesterol. He says it is evidence based and his phd study is based on government funded studies.

i am so interested in the topic now. Peter Attia did a great job explaining it. He would be a great instructor.

This is excellent until the part near the end where you claim that LDL particles are necessarily atherosclerotic. They're not. It's only AFTER they get deranged through oxidation or glycation that they become atherosclerotic. Which means that ApoB as a value to reduce as much as possible is absurd, because this blindly affects normal HEALTHY LDL particles as much as any deranged ones that might be present.

I have very high ldl 127 I’m confused. Im going to cut back on red meat and liver. 😢 284 total. 82 triglycerides hdl 144

You fucking piece os shit you keep saying things and keep saying I don’t believe in that anymore. You’re dealing with people’s life. You are not a real doctor. You peddle in views and followers fuck you and go to hell..so fuck you.

Yeah I stopped paying attention to anything these PC doctors (even some cardiologists, to be honest) say. They are all outdated and have no time (or interest) to actually research about the topic. I will keep off statins no matter what, until I see any RCT study that shows me the opposite. Thanks, Dr. Attia.

at the end of the video when Dr. Paul says that saturated fats are bad, I believe that's wrong. also wrong, is the reference to using canola oil to lower LDL. Many experts doctors etc. agree with what I'm saying. it's my understanding that canola oil along with all the other oils ( except for extra-virgin olive oil, butter, and ghee ) are contributors to oxidation which is bad.

Isn't oxidation a part of the atheroclerosis, damage in endothelium, etc.

I consider myself fairly intelligent but I found this video very complicated!

How on earth does LDL go into artery walls and oxidise there? Will you explain later why you think it's possible? It doesn't make any sense. A whole LDL particle travelling ACROSS the epithelium? Why and how?

i was told i have NAFLD and my bloods seem to have gone up in some areas

colesterol total 224 mg/dl
hdl 36 mg/dl
no hdl 188 mg/dl
ldl 163 mg/dl
triglic 136 mg/dl

any advice ?

I just got my blood work done. My numbers were Glucose: 103H, Cholesterol: 177, Triglyceride: 89, HDL Cholesterol: 38 L, LDL Cholesterol 131 H, VLDL: 18. All mg/dl obviously. They wanted to put me on statins. I said no (for now). Any advice form anyone?

Excellent teaching!

You're an amazing instructor.

Please clear this up for us. Hope this makes sense On LDL being bad actor - other docs in your circle say abt this: is when LDL gets damaged by sugar before it leaves the liver with its package, resulting in LDL not being unable to dock at the cell as usual. This damaged LDL then gets into the bloodstream landing, as you said, in the artery, becoming the bad actor, no thanks to sugar.

And it all evolved from nothing. lol...

Is it proven that the LDLs go into the arterial walls and then get oxidized or is it possible that the LDLs were made from oxidized materials I.E. hydrogenated seed oils?

Very well explained I was taught this at Guys hospital

Well many doctors dont understand cholesterol.....wow

All this being said, LDL increases with low carb diet.

My doctor wanted to put me on a statin for HBP.I shared I have white coat syndrome. The nurse said my pressure was 160 over 100 I should lay down. She was writing a prescription for HBP. I shared with her I would not be filling the prescription. I would be willing to come to the nursing station 3 separate visits. If it is 135 or higher we can discuss it. She made an appt for me to come bsck in two weeks. I went back 3 days later 1st reading 120/80, 2nd 117/80 3rd 114/76. I received a call from the nurse two weeks later stating my cholesterol is too high I needed a statin. Total cholesterol 235 LDL 159 HDL 62 Triglyceride 98 A1C 5.2. I am confused 59 years young 195lbs. I am afraid of sick medicine. I ask her did she want to go over the BP readings. She stated no. I ask may I come back in 6 mos to check my cholestetol she said no the insurance will not cover it. I will work on strenth training, food lifestyle change. I manage to get in 10,000 to 12,000 steps a day. Also zumba 3 days a week. I have to watch carbs and sugar. Grateful for the platform🙏

Comment number 1000! Thank you for this great video :)

What about lp(a) ???

It's good to tell people what they want to hear.

I appreciated this explanation. Thank you.

You can understand the basics of lipids and lipoprotein and still talk about LDL and HDL because the majority of patients will stop listening at the word lipoprotein and have an easier time remembering LDL and HDL. It’s good enough for the overwhelming majority of the non MD-population.

Is keto bad for cholesterol? Also does a low carb diet raise your cholesterol? My numbers were quite high ever since I started doing a low-carb diet. Now I’m scared 😞. Should I avoid certain foods ? What foods are good for someone with high cholesterol?

Thank you. I'd listened to the multi-part podcast with you and Dr Lipid, this summary helps

Bro. it seems that in 2024 u got fat

Is God amazing…as I was listening to all this, how amazing / miracle our bodies created by the Lord. Just mind boggling to me. I didn’t understand any of this but what I do get is how wonderfully we were made by the hand of God. Truly amazing.

So, do i take statins with 240 cholesterol or not?

My hdl is very low. Not sure why. I'm a healthy person not overweight. Why is it low? Am I at risk?

my LDL is 198 and my Doctor insists that I take medication otherwise, I have a high risk of a heart attack, I have no idea should I take this medicine or not

What a fantastic waste of time. Smh

What is a better bio marker/test for heart health?
