Low Carb & Keto: What about Cholesterol?

Low Carb & Keto: What about Cholesterol?


Thanks to Squarespace for sponsoring this
video. Consider the ingredients in the following
low carb high fat recipe. “Two pounds of de-boned white fish, one-half
cup butter and two-thirds pint or more of cream, two tablespoon of flour, the juice
of one half lemon, salt and pepper to taste.” Excluding the fish and lemon, this recipe’s
saturated-fat-packed dairy to carbohydrate ratio is 19:1. Low carb or ketogenic cookbooks with recipes
like this may sound like a delicious way to lose weight, but what about cholesterol and
heart disease? What’s interesting about this saturated
fat heavy recipe is that it isn’t recent at all. It came from an 1895 cookbook, a time when
heart disease rates were at an all time low. Almost every single recipe in The Baptist
Ladies’ Cook Book contains butter, eggs, cream or lard. And, if you rewind to ninety nine years earlier
in 1796 when “The First American Cookbook” came out, you find plenty of recipes using
plenty of lard and fat pork, and a majority of the recipes call for butter, usually by
the pound or half pound. Before 1910, people in the United States almost
exclusively used saturated fat heavy butter and animal fats for cooking and baking. At the time, cooking with vegetable oils was
almost unheard of. But as the process of hulling and pressing
seeds and beans was mechanized, vegetable oils became cheaper than butter or animal
fat. From 1909 to 1999, consumption of soybean
oil in the United States increased by more than 1,000-fold per person, margarine consumption
increased 12-fold, but consumption of butter and lard decreased by about four-fold each. Sometime after 1910, there was concern about
the growing rates of heart disease, and president Eisenhower’s heart attack in 1955 really
got the ball rolling on figuring out what causes heart disease. There were a couple places to look: for example,
smoking rates were on the rise along with the rise of heart disease: President Eisenhower by the way, had been
a four-pack-a-day chainsmoker a couple years before his heart attack. Despite this, and the fact that the president’s
attack occurred right in the middle of the rapid decline of animal fat consumption and
rapid rise of vegetable oil consumption, saturated fat took the blame. You probably know the rest: it was found that
cholesterol is contained in the plaques that clog arteries, and saturated fat increases
your cholesterol. Thus, “artery clogging saturated fat”
became a common phrase. But before we get into whether having high
cholesterol from eating too much saturated fat causes heart disease, let’s look at
cholesterol itself. What is it for? Well, first off, it’s very important for
maintaining the integrity of cells in your body. Without it, your cells would turn to mush. A huge function of cholesterol is making and
metabolizing hormones. Hence, cholesterol levels naturally rise throughout
pregnancy, a time in which the body is producing all sorts of hormones to manufacture a fresh
human. A 1997 study of university students found
that cholesterol levels rose “proportional to the degree of examination stress.” When the body is under stress, it produces
cholesterol to make hormones that help deal with the stress. If you are awakened by a burglar trying to
break into your home at 4AM, but have a checkup later in the day, you can expect your cholesterol
levels to be sky high and for your doctor to prescribe you a statin – a cholesterol
lowering drug. Cholesterol’s importance in hormone production
also explains why men taking statins have been found to have lower testosterone. So, I hope we can agree that we need some
cholesterol. But just how good is less cholesterol? A 2001 paper documents the changes in 3572
elderly people’s serum cholesterol concentrations over 20 years, and compared them with rates
of death. They found that the group with the lowest
cholesterol had the lowest rate of survival. The author’s interpretation? “We have been unable to explain our results” You may have heard of the “French Paradox”
– a term coined in the late 1980’s that refers to the particularly low obesity and
heart disease rate in France despite people getting as much as 40% of their energy intake
from fat with 16% of it being saturated fat – this is three times the amount of Saturated
Fat the American Heart Association recommends. One theory is that red wine is what allows
French people to eat so much butter, cheese, cream, foie gras, and pate yet stay so healthy. So maybe if French people lowered their dietary
saturated fat and therefore cholesterol and drank the wine, they’d be even healthier. Well, a 1989 paper tracking the mortality
rates of 92 elderly women in a nursing home in Paris found that rate of death was 5.2
times higher in those with the lowest cholesterol. But we know total cholesterol is somewhat
outdated, and now the concern is about LDL – the so called “bad” cholesterol. As shown in a review written by multiple doctors
in departments like Cell Biology, Chemistry, Endocrinology and Nutrition science, compared
to other diets, when you go on a low carbohydrate diet, many biomarkers improve: your weight
goes down, your hemoglobin A1c goes down, glucose is down, triglycerides are way down,
but this small increase in LDL may have some people worrying. In this talk by Peter Attia, he explains:
“We were taught that LDL cholesterol is the big risk, right? If your LDL cholesterol is high, you are at
risk for heart disease. This is a study that looked at 136,000 patients
admitted to the hospital for a coronary artery event and in these patients they looked at
LDL cholesterol level and you can see that nearly 50% of them had what you would consider
a low LDL cholesterol level.” Many scientists believe oxidized cholesterol
to be the real problem as it initiates the process leading to the buildup of plaque in
the arteries. So then, how does it become oxidized? One way is, ironically, through the effects
of consuming so called “heart healthy” vegetable oils. The problem with the polyunsaturated fatty
acids in vegetable oils is that because of their structure, they are unstable. Meaning, when exposed to oxygen or heat, they
can form toxic byproducts and free radicals. Free radicals which can oxidize cholesterol
and thus lead to heart disease. So when you heat vegetable oils, free radicals
as well as small lipid fragments called aldehydes can form. Aldehydes are well known to be toxic. A hangover is suspected to be the result of
alcohol being metabolized into acetaldehyde. Research by Martin Grootveld, a professor
of bioanalytical chemistry and chemical pathology, showed that “a typical meal of fish and
chips”, fried in vegetable oil, contained as much as 100 to 200 times more toxic aldehydes
than the WHO safe daily limit. In contrast, frying butter, olive oil, coconut
oil and lardproduced far lower levels of aldehydes. Maybe McDonald’s ought to switch back to
making their fries in beef tallow, as they did before the early 90’s. “And I thought when they first started out
the french fries were very good. And then the nutritionists got at them and
it turned out to be erroneous that beef, tallow, fat was bad and…” But, vegetable oils, for example corn oil,
do an excellent job of lowering cholesterol. We’ve known this since the 1960’s. Here’s Dr. David Diamond explaining a study
on this from 1965: “They had one group that was put on a low cholesterol, low fat diet
and they had a couple tablespoons of corn oil per day. The other group as you see here, it says no
advice was given to the control patients. And the outcome was quite nice as far as the
cholesterol. So the study was a success as far as reducing
cholestero. But then, when you look at the outcome. The outcome is very straightforward. To stay in the study you have to stay alive. So now when you look at these two groups and
look at whose still in the study. And so, the people on the low fat low cholesterol
corn oil diet, only half of them were left. So twice as many people had heart attacks
and died in those that had the corn oil.” Another tragic consequence of replacing saturated
fats with polyunsaturated vegetable oils is losing out on the heart protective effects
of the fat soluble Vitamin K2 found in animal fats. The importance of vitamin K2 in heart health
is shown by research on vitamin K2-dependent reactions. For example, gamma carboxylation, requires
vitamin K as a cofactor. And, if the glutamic acid residues of gla-containing
proteins are not carboxylated, calcium cannot be properly bound. You don’t need to remember all that, but
it simply means that Vitamin K2 is necessary to take the calcium out of your heart and
put it into your bones. Calcium deposition in the vascular system
is a consistent feature of heart disease. Interestingly, as this 2004 paper shows, vitamin
K2 intake reduced mortality rates from heart disease and all causes, but vitamin K1 (found
in soybean and canola oil) did not. And, more recently we’re seeing articles
like this: Let’s take a brief moment to review how
our eating patterns have changed following dietary recommendations. Less Whole Milk, More Skim Milk, A little
less butter, Way more polyunsaturated oils, Less eggs and Beef, and More lean Chicken
and Turkey. Top it all off with a gigantic increase in
sweet syrup. You might still be wondering, “if it’s
not the cholesterol, then what causes heart disease?” Let’s take a look at a study of patients
that have a condition called “familial hypercholesterolaemia” that causes them to have abnormally high cholesterol. We’re supposed to keep our LDL below 100
to be healthy, but in these people, it was nearing 250. But, a portion of them had heart disease and
the others did not. There’s no significant difference between
total cholesterol, or the so called good or bad cholesterols. So what was different? Clotting factors. Those diagnosed with heart disease had significantly
greater baseline clotting factors. Here’s a study showing that Cardiovascular
disease clearly increases with an increase in the clotting factor fibrinogen. As Dr. David Diamond Points out: if we take
a look at the primary risk factors for heart disease: Obesity, Diabetes, High Blood Sugar,
Smoking, Aging, Inflammation, Stress and Hypertension, these are all linked to platelet activation
and clotting. The point I want to make is that at the very
least, there are much better places to look than cholesterol in trying to prevent heart
disease. For example, Dr. Mann Kummerow suspected trans-fats
to be the problem. Among other unhealthy effects, trans fats
inhibit Vitamin K2 dependent processes, promoting calcium build up in the heart. Biochemist and two time Nobel Prize Winner
Linus Pauling suspected Vitamin C deficiency to play a role as low Vitamin C stimulates
the production of the heart disease promoting Lipoprotein (a). Another big suspect is chronic inflammation There are many factors that play into this
very complex condition, and more and more data is showing that saturated fat in the
context of a low carbohydrate diet is not one of them. Despite some data like this on 1998 Europe
suggesting that more saturated fat results in less heart disease, the theory that saturated
fat causes heart disease has prevailed for quite a while and radically changed the way
we eat. This video was brought to you by Squarespace. If you want to make a professional grade website,

  1. Can years of damage ingesting vegetable oil fried foods be fixed eating like we should have been eating as people usually did over a hundred years ago before heart disease was ever an issue????????

  2. How soon before doctors say these things? or are doctors right now? The worst part about this sort of information is it means i potentially have to disregard professional medical advice

  3. Scientists are the worst people on the planet. All you reddit fucks who "Love Science!" are absolute retards

  4. If there truly is vitamin K2 in animal fats then why is it not listed on the label? i hear similar claims yet it is never listed in nutrition facts. Can anyone tell me why?

  5. Proof that in my body at least eggs do not raise cholesterol. Last year I ate maybe 2 or 3 eggs a week. On keto this year I eat about 28 eggs a week. Last year's cholesterol 244 At this year's cholesterol 244. I have been between 220 and 244 for the last 10 years. This is probably what my body needs so I am not concerned. By the way triglycerides last year 100 this year 64. HDL last year 54 this year 68. LDL last year 180 this year 163.

  6. im all for butter, but i actually hate the taste of milk and cream, not to mention lactose intolerant. I don't understand why people like it …

  7. I hate to disappoint people, it's not what you eat, it's your Gene's, some can eat what the government says is "healthy: and have heart attacks if they have a family history, where some can eat the "worst" foods and never have any clogged arteries

    It's that simple

  8. Healthy diet is simple. 1. Don't snack all day long, Have an eating window preferably within 4 hours every day and fast the rest of the day. This will control your appetite and keep your insulin stable throughout most of the day. 2. Do not consume processed foods and sugars. 3. Drink around 2 L of water a day. That's it. It will be a bit tough in the beginning but after 2 weeks you will feel great, and more importantly your energy levels will be stable.

  9. Before I started keto my cholesterol was 244. At that time I was eating maybe 2 to 4 eggs a week. The rest or carbs in the morning. After starting keto I started eating 3 to 4 eggs a day. So from four eggs a week total to about 21 to 28 eggs. Also I found a guy in the area that raises chickens and ducks. So I buy his duck eggs which I like even better than chicken eggs. The duck eggs are larger than chicken eggs by about 1 1/2 to 2 times the size. After about a year of eating like this I had my cholesterol checked. It’s still at 244 had not budged. And I’m not concerned at all about it because all my other markers improved dramatically. Cholesterol is the passenger not the driver.

  10. The government is a tool used by the capitalists to control the wage slaves. The advise the government gives you will be in line with what is convenient or useful for the capitalists. Competition between governments and corporations creates a selection pressure for this behavior. Simply put, they CAN'T afford NOT to do this. Knowledge is power, don't trust the government to give you adequate knowledge, that would be a threat to their power base.

  11. what the fuck should I eat bro. Your videos are useful, but all I get from them is that I can't trust any doctors or resources online because everyone trying to sell some kind of food is saying their shit makes you healthy and everything else will kill us. I've started to realize that almost all research funded in this shit is by people with conflict of interests and that we can't even trust people with PhD's anymore because they sold out to anyone who would fund their fake ass research.

    WHAT THE FUCK IS GOOD TO EAT GODDAMNIT, HOW DO I NOT DIE OF HEART DISEASE I STILL DIDN'T LEARN ANYTHING

    Please provide some sort of conclusion to all your research, so far most of your videos have amazing info but you do not suggest any actions to take. I understand you don't want to tell people what to do but I'd like your opinion every now and then.

  12. So, in the end, we've been going in circles in nutrition science for ages. We still (mostly) have no clue at all. Great.

  13. High carb or high fat cant have both get sick and blame one of them just eat balanced and unprocessed food workout thats it

  14. I think carbohydrates and sugar are what increase cholesterol and the possibility of heart disease !!

  15. funny, i have low clotterrate to my veins, but high cholestorol levels, people say i need to get my cholestorol down, which i find weird. i just need to lose some weight by movinv more. 🙂

  16. one of the more disengenuous vids you are likely to watch. notice that the dude omits all the many studies that showthe exact opposite of his hype, and that every major medical institution in the country disagrees. when he redo's perhaps #1 he'll take note of the fat industry funded studies he is citing.

  17. The Channel Townsend’s specializes in 18th century cooking, I highly suggest checking them out

  18. Well, here is an oft ignored fact.  Serum cholesterol is incompatible with life.  You see fatty acids do not really like being in a water based fluid like blood.  What is called cholesterol (VLDL, LDL, and HDL) are not cholesterol at all.  These are just transport mechanisms for fatty acids.

  19. Duh, in the old days people died young of infectious diseases and trauma. They didn’t live long enough to suffer the effects of heart disease or diabetes.

  20. So basically if we sum up all your Nutrition videos the outcome is Go low on Carbs , low on Sugar , Eat lots of fats and protein and if possible One meal a day!!

  21. I eat like twice as many eggs a week as recommended by dietary standards, and my cholesterol is much lower than it was when I was eating a low fat diet. Obviously that's just anecdotal, but it's interesting to me.

  22. this may be a dumb question, but which oils count as vegetable oils? searching on google, i get contradicting responses about whether or not olive oil is a vegetable oil. what about coconut oil?

  23. Hmmm…. why would a theory prevail so long? Here's a story, little one, about two men: Ancel Keys and George McGovern, and aaaallll the Midwest crop farmers….lol.

    "It is the plain fact that the farmer raises wheat [corn/soy – 4S] because it takes less labor than any other crop–because it enables him, after working no more than sixty days a year, to loaf the rest of the twelve months." – H.L. Mencken

  24. The recipe you mention at the beginning of the video. This is not representative of how the majority of people used to eat. Butter and cream were expensive. Cookbooks were written and read only by the literate. This was the food of the nobility, who were often obese and ill, but they also ate sweets. The majority of people who were not as well off ate whatever was cheapest, from what I know about my family some 100 years ago in central Europe for instance, this was mostly vegetable stews with a bit of smoked meat inside for the flavor, with bread made out of corn flour or whole wheat. They ate a moderate to low amount of eggs and cheese, but they did use lard, also moderately. They ate beans, cabbage, turnips and buckwheat and a lot of soup made with bone broth. I absolutely believe that refined carbs are the main culprit behind the obesity and heart disease epidemic, but I also wouldn't discount the role of saturated fat. Not that this can be concluded from the way my ancestors ate or anything, I just really didn't like how the first example was used as evidence that saturated fat doesn't cause these problems.

  25. Seems like someone’s trying to kill us sublty and slowly and in the same time trying to reduce our fertility…. hmmmmm i wonder (((why)))

  26. This specific cholesterol guide “Hοzantο Axy” (Google it) is a whole new medication I began to try out. Particularly, I started using it to lower my cholesterol level at the recommendations of my DOCTOR. I took one caplet per day for two months well before I had my check-ups. It has reduced my cholesterol to 30 points. There’s no question I would suggest this one to my very own loved ones. Needless to say, I am going to consistently use this. .

  27. I did start to use this particular cholesterol guide “Hοzantο Axy” (Google it). Specifically, I started off taking it to lower my cholesterol at the recommendations of my very own DOCTOR. I took a single caplet per day for 2 months just before I had my check-ups. It has lowered my cholesterol to Thirty points. I will unquestionably proceed using this solution and even advise it to my very own friends and family. .

  28. Cholesterol is NOT RELEVANT! Anyone that states that Saturated Fat has ANYTHING to do with Heart Disease is simply Ignorant.

  29. Great video; thoughtful arguments. It is amazing how brainwashed we all are or have been about fat in our diet. I started Keto on 2/14/19. I’ve lost 40?lbs, am 170 down from 210. I enjoy delicious pastured eggs ( our own) , with bacon and or sausage every morning, with some butter and cheese of course. I had my biometrics done in May. My HDL was 66; I could never get it above mid fifties before, even when exercising a lot , all this without exercising. A1C down (5.1) glucose down; usually would be just over 100 to 110; it was 84. I’m 62 yrs old, but feel like 42. Went to my annual checkup last month; Doc says he’ll have to talk about a statin if my LDLdoesn’t come down. Unbelievable.

  30. You must be a advocate for the meat and dairy industry or your sponsored by them because you really push that. How about doing a video on all the benefits of eating meat and dairy and all the health benefits of meat and Dairy and also vitamin K2 your best levels do not come from animal products. I'm just saying

  31. This video showed up in my recommended probably because I've been watching Keto vids lately. Started Keto 3 weeks ago and have burned over 17lbs of fat.

  32. Well if you had heart disease I dare you to eat that much meat butter and whatever fat… look up Dr Esselstyn and what he did with his actual studies to revert CVD. Don’t fool yourselves with a youtuber and his compilation of studies and opinion.

  33. Understanding the purpose of cholesterol and Carbohydrate metabolism will open your eyes. Knowing what and how humans get fatter and the composition of fat cells is the knowledge the public need to learn.

  34. It amazes me that that we can split atoms, have self driving cars, pocket computers, yet we still don't really know how our body works.

  35. I almost went to the emergency room due to the high fat content in this diet. Please be very aware of the gallbladder before you start with this diet. The gallbladder sometimes cannot process all this fat and you start having horrible stomach pain, gases, and diarrea. Be very careful!

  36. You need D3 and K2 mk7 to transport calcium out of soft tissue. This will leave unstable cholesterol unless you reduce inflammation too.

  37. The body produces plenty of cholesterol. Adding it into your diet is a recipe for disaster. This video is completely misleading and even dangerous.

  38. Now i am curiouse if u have a video, were the knowaldge of all the videos made with health in mind, one that gives us tips on how to plan this all out. Like asking doctors, or how do we calculate the limit of intake for each of ourselves wether it be protine mineralls glucose etc etc. And try and match it to our active hours. In the end how do we calculate our personal daily needs

  39. In 1800, US life expectancy was 37, in 1900 it was 47, and in 1910 it was 49. The average American was already dead many years before the deleterious health effects of the ultra-high fat diets of those times appeared.
