The many faces of LDL

Pam has an LDL cholesterol of 144 mg/dl.

To most people, this means that she has a mildly elevated LDL value. Many people would respond by cutting the saturated fat in their diet. Most physicians would concur and talk about prescribing a statin drug.

Let me tell you what an LDL cholesterol of 144 mg/dl means to me:

1) It could mean an LDL of all large particles (which is good) or an LDL of all small particles (which is very bad). Or, perhaps it's some combination of big and small. I can't tell which just by knowing that LDL is 144.

Small LDL responds to a diet reduced in processed carbohydrates and wheat flour; large LDL does not. Small LDL responds in an exagerrated way to niacin; large LDL does not. It makes a difference.

2) It could mean that, hidden within LDL, is lipoprotein(a), or Lp(a). Recall that Lp(a) is a high-risk genetic pattern that can provide the false appearance of high LDL cholesterol. If Pam were prescribed a statin drug, it would have little effect and little benefit. (See Red flags for Lipoprotein(a).)

Knowing that Pam has Lp(a) can point us in an entirely different direction than just LDL cholesterol. It might mean high-dose fish oil, a more serious approach to niacin, hormonal treatments like DHEA or testosterone. It might mean more attention to warning your children about the possibility that they, too, might share this genetic trait.

3) It could mean both small LDL and Lp(a) are present simultaneously, an especially dangerous combined pattern that is among the highest risks for heart disease known.

4) Because Pam's LDL of 144 mg/dl was not measured, but calculated, it means that it is subject to tremendous inaccuracy.

In my office, calculated LDL cholesterols can be inaccurate by 50 or 100 mg/dl--commonly. So Pam's LDL of 144 mg/dl could really be 70 mg/dl, or it could be 244 mg/dl. Once again, it's a big difference.


Just like The Three Faces of Eve, the 1957 film in which Joanne Woodward played the three wildly different sides of Eve's personality--the daytime Eve White, the fun-loving and daring Eve Black, and Jane--so can LDL assume several different faces, all with different personalities, different implications.

Accepting LDL cholesterol as LDL cholesterol is a fool's game. It is only a starting point, nothing more. Accepting a statin drug based on LDL is, likewise, a trap fraught with uncertainty, the potential for limited or ineffective results, the price being your heart and health.

"This diet works great," Don declared. "But I think I've lost too much weight."

At 67 years old and 5 ft. 11 inches, Don began the program weighing 228 lbs (BMI 31.9). Because of high triglycerides, high blood sugar, high c-reactive protein, and excessive small LDL, I instructed Don to eliminate all wheat products from his diet, along with cornstarch and sweets. His intake of lean meats, eggs, vegetables, oils, raw nuts, etc. was unlimited.

Don now weighed 194 lbs, down 34 lbs over 6 months (BMI 27.1). Triglycerides, blood sugar, blood pressure, and well-being had improved dramatically; small LDL, however, had dropped only 30%--still room for improvement.

"My friends say I'm too skinny. They ask if I have cancer!"

I've heard this many times: Someone loses weight in a relatively short period of time and friends and family tell you you're too skinny. "It must be cancer. Nobody loses weight like that."

Unfortunately, many Americans have forgotten what normal looks like. Normal is certainly not a 190-lb, 5 ft 4 in woman, nor is it a 228 lb, 5 ft 11 inch man. But Americans have put on so much weight that the prevailing view of what constitutes "normal" weight has been revised upward. Normal is closer to what we see in old movies from the 1940s and '50s with people like Jimmy Stewart and Donna Reed. That's what we are supposed to look like.

So Don actually remains mildly overweight but is judged as "too skinny," or even cancer-ridden, by friends and family.

Ignore such comments. As you lose pounds and approach a truly desirable weight, realize that you are returning to the normal state, not the vision of "normal" now held by most Americans.

    This is funny because as a 5'11" male I'm 165lbs and considered by some to be "emaciated" even though I have 10% body fat and quite a bit of muscle. I remember 45 years ago as a kid when my 6' tall father weighed 170lbs. Nobody ever called him skinny because he pretty much looked like all of his friends. He was considered normal at that time. I remember his weight at that time because he often boasted about it seeing as how he only weighed 125 lbs when he was drafted into the Navy.

    We have indeed forgotten what normal looks like.

    I think you're onto something with this 'standards' business. I'm down to 171 pounds (nearly 70 pounds!) since going on my diet. It hasn't been a FAST loss, but people who haven't seen me in a while are surprised and remark that I look like a 'stick'.

    Since when did 171 fall into the 'stick' range for a 5'4" woman? Maybe >30 BMI is thin for Kentucky.

    Note: I love Jimmy Stewart!

    Excellent post!  My question, then, is, where do we find a reliable place to find out what our desirable weight IS?  I'm not sure I trust the ones I have found on-line.  Can you recommend one?  Especially for folks over 50.  Thanks!

    "Unfortunately, many Americans have forgotten what normal looks like. Normal is certainly not a 190-lb, 5 ft 4 in woman, nor is it a 228 lb, 5 ft 11 inch man."

    So true.  Walking through the airport terminal on a visit from Asia immediately oriented me back to the US with the long chain of fast food franchises and big, waddling passengers.  A trip to Walmart to see morbidly obese people in motorized carts is a tourist attraction for Asians.  They can't believe it until they see it.

    Yes, this blog is definitely detrimental to my fat.

    For five months, I've swam, taken fish oil, cut out juice and bread from my fridge.  As a result I've lost 16 pounds, 12 beats per minute, and 3 off my blood pressure.

    I'm currently 29m 6'2 and at 184 lb, 48 bpm resting, and at 125 for blood pressure.

    It is truly scary to see how easy it is to lose weight once you know how bad certain foods are.  It is borderline addicting!

    I'm curious to see if I will hit an equilibrium or I will have to do something to stop the weight loss once I reach 175-180.

    This is so true, many of my friends think I'm extremely skinny, yet I'm at my optimal weight. My mom refuses to lose more weight,she says "people will say that I look old and sick"

    You hit the nail on the head. I too, as a 50-something year old male, was about 220 at 5'10" last year this time, and as I approached 185 mid-year, several folks asked, "Are you all right?" and "Did you intend to lose the weight?" Yet I still am not at an ideal weight for my height, and although I look slim in comparison, I still have abdominal fat that needs to go. I've also had people tell me, "You look too thin," and "Don't lose any more weight." We must recapture a sense of normal. However, during a recent visit to a Glen Ivy Spa in So. Cal. my wife and I marveled at how many grossly obese people there were sauntering around in swimsuits. We've definitely got a problem here. For me, I'd rather look like Jimmie Stewart or Jack Lalane or Art Devany, and I don't care what anyone else thinks about it!

    I had a friend say to me once, "you lost a lot of weight, are you sick 'r something?"

    I'm a 5' 9" 49 y.o. North American male and went from 192 lbs. to 168 lbs. in nine months.  This was a couple years ago. I lost most of it off my mid-section and face.  I have the incredible shrinking waist (now 30 inches.)

    I did this by simply eliminating grains, starches, and sugars.  I actually had to slightly increase my daily calorie intake (than when I weighed 192) because I too was concerned I might have been losing too much weight.

    When I share with family and friends why I look so lean, that it's from permanent grain, starch and sugar abstention, they always respond with "oh no, I can't do that"  or "how can you do that?"

    This is reassuring. I've been worrying because, since I started a heart healthy diet, I've gone from 183 lbs to 167 lbs, which is less than I weighed when I was 18 years old (170).

    Hi, Jeannie--

    There are a number of ways to determine ideal weight. BMI, though an imperfect concept, is a good starting place. Here's a BMI calculator: http://www.nhlbisupport.com/bmi/

    This gives me an idea for a future post: "What is ideal weight?"

    There's also the problem of finding clothes that fit. I'm a 5'11" male and weigh 152lbs. I've got a 32" waist, but when I try on 32" waist pants they fall off of me because they're really 34" (I believe this is called vanity sizing), so I look for the 30" waist pants and guess what? There are none!

    Maybe it's because I live in the South, but 30" waist pants are pretty much non-existent, and the ones that I do find are always too short.

    My wife used to think I was too skinny, but then she remembered all her Oriental friends back in California who are as skinny as I am. For them it's considered normal.

    I say revel in it!  I knew from past temporary weight loss that people would start to notice after I lost 30 pounds or so.  Since I needed to lose 70 to get to ideal weight, I also knew that those comments were nothing but signs of sucess.  We truly have adapted to a new normal in our perceptions.  The shock value does diminish over time though.  Now three years out from adopting a healthy diet (currently 6'3", 190 lbs.), I got all the comments along the way, but now people have adjusted to my new look (as have I).  Once in a while though, I see someone, usually business-related, that I haven't seen for a few years, and they're shocked.  I just enjoy it, and try to recruit them over from the dark side.

    The thing that I find interesting now is that, while I was losing people were interesting in why I was losing, and several adopted the low-carb/paleo approach with great success.  But now that I have reached an ideal weight, the memory of the previous me fades, and few see me as a potential source of healthy diet information.  I think some actually think I must be a bit of a freak for having done so well, and so there's nothing useful to be learned from me by non-freaks.

    I am another who lost weight when I dropped all grains and sugars and greatly limited high carb veges and fruits. The weight just melted away. I did not need to lose much and when I hit 20 lbs, the weight loss stopped. I have been at 120-125 for many months now. I am 5' 4". I never feel hungry eating the higher fat diet. Honestly, sometimes I do miss the junky food but not enough to eat it and jeopardize my health.

    I wonder if anyone has information on cornstarch and why it places right next to wheat as a 'food' to avoid?  I have seen a great deal of convincing argument with regard to wheat, but almost none with regard to cornstarch (other than for those who may need to closely watch blood glucose levels).  

    If anyone can lead me to more information on how it affects our organism, I would great appreciate it.

    Dr. Davis.  If you do a post on ideal weight, it might be helpful to include a discussion of muscle mass.  Many athletes are heavier than those of comparable ages in the general population, but have body fat levels that are extremely low.  There is a trade-off with weight loss and muscle loss, and I suppose a happy equilibrium at some leve.  Perhaps body fat level is a better gauge than absolute weight level, but hard to accuratley measure.  Thanks,

    I read an newspaper article about how parents in the UK didn't realise their children were obese. Yes, that's obese - not just overweight.

    We have lost sight of what it is to be of normal weight. I catch myself looking at people's sizes in old movies to remind myself of what "normal" should be.

    I really don't like the BMI indicator. First, there is no differentiation between males and females or body type. Fit males who have any kind of muscle tone or who may be big-boned will invariably have a BMI greater than 25. I'm very close even though I'm only 10% body fat.

    Instead, I think that a better measure is to ignore weight altogether and get your % body fat computed. Ideally it should be 14-17% for males and 21-24% for females.

    I too have difficulty finding pants that fit. I wear a 30" waist. Its tough to find anything smaller than a 38"-40" waist which is pretty sad.

    Based on the posts here on HeartScan and my brothers insistence Atkin's was his preferred effective weight control solution, I started eating meat again after 10 years of being a pescatarian. I put on 12 lbs in 3 months.  OK, I am not too keen on eating slabs of meat and may have gone overboard with sausage meat / chicken wings but I hope my next blood test will show an increase in HDL as a result of the added fat and lower wheat/grains

    BTW. I stopped my 20mgs crestor and got a base line several months back (too scary !). I have taken 20mgs and 40mgs crestor with the latter leading to some muscle pain but perfect LDL (60). HDL only went up with Niacin (31 to 45 )

    What I want is no more than 20mgs crestor (which gives me LDL circa 75 and I can tolerate well) and to elevate my HDL to 60 without having to eat raw cow.

    This site is a great resource. I would like to see Dr D square off against the celeb TV Dr Oz who pushes high grain diets and low saturated fat.

    I think some of the response to too skinny is because folks are faced with how 'not skinny' they are looking at those who are not.

    I'm a caucasian male, 6'2" and I've been healthily below 160.  I have a thin body.  I don't know if it's because my bones are smaller, or what, but this is normal for me.

    And, I feel for the thin folks in the south.  When we lived in TN for a few years, I had a heck of a time finding 32" waist pants.  Now that I'm back in CA, it's much easier.

    Jimmy Stewart was thought too skinny by Hollywood and the Army at the time.  When he was first signed to MGM they recognized that Stewart had an uncanny screen charisma and great star potential, but they considered him just so goofy looking that they didn't buy him having any male star sex appeal.  MGM wanted someone to compete with Tyrone Power, Clark Gable, Spencer Tracy and up and comers like Cary Grant (Grant would be a better example for you than Stewart).  Before MGM ever put Stewart in a movie they put him with one of the studio weight trainers, hoping to add some muscle to his physique.  The trainer had Stewart lifting weights and drinking a gallon of milk everyday.  After a month of this regimen Stewart had gained about three pounds, mostly of bloat.  MGM put him in a variety of bit parts but they figured he was basically useless to them so they loaned him out to Columbia for a pair of pictures, You Can't Take it with You and Mr. Smith Goes to Washington.  Stewart's star was made and he returned to MGM to make a slew of great films, Destry rides again, Philadelphia Story, & The shop Around the corner.  Stewart came from a very patriotic, midwestern family.  in 1940 Stewart basically quit his studio contract (after filming A Mortal Storm) and recognizing the world situation, he went to enlist in the Army with the idea of entering the Air Corps to train as a pilot.  He was rejected flat out because he did not weigh enough for the minimum standard to enlist.  And Stewart was 6' 3&3/4" he weighed next to nothing!  Since he was only a few lbs under, Stewart went back the next week, this time after waterloading himself.  he barely made it through the physical before bursting, but he was able to eek over that minimum weight standard by a single pound.  By the time Pearl Harbor hit, Stewart was a certified pilot and he spent most of the war continually flying bombing missions over Europe.

    Cary Grant on the other hand, would be a superb example. Grant began life as a circus tumbler, and he maintained his athleticism throughout his life.  His remarkable lack of aging until his final decade was due to his  eschewing alcohol and smoking in his private life, which was both very rare at the time and ironic considering the suave characters he played always drank and smoked.  He may also have been one of the oddball anti-sugar hollywood types (Gloria Swanson was one) that refused to eat anything with sugar in it.  But I'm not certain on that.

"We don't believe in heart scans"

"We don't believe in heart scans"

Tim's CT heart scan score was an earth-shattering 3,447, clearly in the upper stratosphere of percentile rank. Risk of heart attack: 25% per year. At age 58, it was a wonder that nothing had happened yet.

Tim went to the Cleveland Clinic for an opinion, long a powerful bastion of heart procedures. The consulting cardiologist told Tim, "We don't believe in heart scans. They're wrong too often."

An opinion from a widely-respected cardiovascular center. If they don't "believe" in heart scans, does that mean they "believe" in stents and bypass surgery? Does it mean that the thousands of research studies that have now been published on the value of heart scanning are pure fiction? Is there a choice to believe or not believe?

I continue to be shocked at the extraordinary ignorance on the topic of heart scanning among my colleagues. The number one killer of Americans and you still rely on stress tests?

Why this perception that heart scans are "wrong too often"? What this cardiologist means, I believe, is that when people are taken to the cath lab for catheterization, a substantial number of those with positive heart scan scores don't have "blockage". But I could have told him that even before the heart catheterization.

There is an expected and well-documented likelihood of finding significant "blockage" based on your heart scan score. At Tim's scary score of 3,447, what is the likelihood of "blockage" of 50% or more? It's around 40-50%. That means that half the people at this score will have a blockage sufficient to justify inserting stents or undergoing bypass surgery, half will not. There will indeed be many plaques, but none severe enough to block flow.

Does that make the heart scan wrong? I don't think it does. Just because you don't need a major procedure to "fix" blockages does not mean that no heart disease is present. Without preventive efforts, Tim's heart attack risk remains an alarming 25% per year--whether or not he gets stents or bypass. The only treatments that substantially reduce this risk (in an asymptomatic person) are preventive efforts, not procedures.

Yet cardiologists like the one Tim consulted at the Cleveland Clinic regard heart scans as something "he doesn't believe in". I would suggest a return to the textbooks and published literature and re-thinking how heart disease should be managed.

Heart scans should provide an opportunity for prevention, not an opportunity for profit.
