Can you find a more polarizing topic than statins? One article says they are miracle drugs that should be given to everyone. Then you turn the page, and you read how they are poison and you should stay away from them no matter what.  How can one drug cause such differing views? And which should you believe?

The statin debate has intensified ever since the 2013 ACC/AHA cholesterol treatment guidelines increased the number of people without heart disease who “should” take a statin to 43 million Americans. That is for primary prevention, meaning the individual has never had a diagnosis of cardiovascular disease, never had a heart attack, and never had any type of a heart problem.

As you can imagine, this has been a windfall for the drug companies. But are we healthier and better off as a result? That is unknown.

The problem is understanding the bias of whoever is writing the story.

Subtleties of Science

But wait, you say. Won’t the science tell us if statins are good or not? Isn’t it an objective fact if they are good for us?

Not so fast. Beauty is in the eye of the beholder, and so is the application of science.

Are you getting advice from someone who believes prescribing more medicine is better? Or someone who believes a more natural lifestyle is better? 

Are you reading a report sponsored by the pharmaceutical company that paid for the research?

Or are you getting advice from a scientist who is more focused on statistical benefits, or someone who is more concerned with the potential benefit for the one individual they are taking care of at the moment?

It is a confusing sea of conflicting information, and you have to find which approach resonates more with your beliefs and your life.

The Three Keys

Regardless of who you are and your beliefs, I promised you the three most important things you need to know about statins. Here they are:

1. All statin studies are worthless! That’s right. All statin studies that have been done to date are worthless and don’t apply to anyone who follows healthy lifestyle principles.
2. Statins will not prolong your life. Not at all. Not for a single day.
3. Statins DO reduce your heart attack risk, by about 0.7% over 5 years.

All of a sudden, statins don’t seem so powerful, do they? Let’s go deeper into these points to learn why.

1-All Statin Trials Are Worthless

When designing a trial, you have to decide what your control group is going to be. You have to show that the drug is better than something. The key is defining what that something is.

Therein lies the problem. In order to show beneficial effects, primary prevention statin trials need thousands of subjects, studied over years. That is very expensive to do. The vast majority of trials, therefore, rely on drug company funding.

Do you think they are going to fund a trial that makes it easier or harder to show a benefit? Of course, that was a rhetorical question.

Pharma companies don’t have an interest in your health and wellbeing. Their priority is to their stock holders and their bottom line. They are going to sponsor trials that are most likely going to benefit them.

How does this make the trials worthless? They compare statins to “usual care.” That means a brief, and ineffective attempt to educate people about healthy nutrition and physical activity.

In addition, the specific nutritional guidance that was used has always been a low-fat diet. As we now know, what does a low-fat diet usually include? Lots of sugars and simple carbohydrates. What does that diet do? Increase your risk of obesity, diabetes, inflammation, and eventually heart disease.

That’s setting the bar pretty low to show a benefit from statins. And that is exactly what the drug companies want.

What we need is a control group that is involved in a comprehensive lifestyle intervention program. A program that helps participants get regular physical activity. Helps them eat vegetable based, real food, low in added sugars and simple carbs, and high in natural healthy fats.

Since that is the way we should all be living, THAT is what the control group should be. I guarantee you, the results would be far different compared to the standard control groups used to date.

That is the trial the drug companies never want to see and will never fund. And that is why all statin trials to date are worthless.

If you can focus on proper lifestyle interventions, using healthy foods, physical activity and stress management as medicine, then we have no idea what effect, if any, statins would have. But I assure you it will be minimal if any benefit.

2-Statins Will Not Prolong Your life

You read that right. For people who have never had heart disease before, the multi-billion dollar drug won’t help you live longer. The overwhelming majority of primary prevention trials involving statins show no difference in overall mortality between those who took the drug and those who did not.

That surprises a lot of people. Statins are promoted as if they are wonder drugs that save lives left and right. That’s good marketing and good PR. Reality is far different.

If they don’t help you live longer, they must increase the quality of your life, right? Nope. In fact, 30-40% of people on statins will experience muscle aches and weakness causing them to exercise less and decreasing the overall quality of their lives.

So, if they don’t help us live longer, and they don’t increase the quality of our lives, why do we take them????

3-Statins DO Reduce Your Heart Attack Risk

If the news was all bad there wouldn’t be any debate about their use. But the truth is that statins do reduce the risk of heart attacks, and that is why in some cases it may be beneficial for you to take one.

But the big question is: How much do statins reduce your heart attack risk? The answer is not as much as you would think. Considering the recommendations keep getting more and more aggressive for statin therapy, you would think statins would be immensely powerful at reducing heart disease risk.

In reality, they reduce the risk of a heart attack by 0.7-1.5% over 5 years. That means you need to treat 66-140 people for 5 years to prevent one heart attack.  (as an aside, for people with pre-existing heart disease, so called secondary prevention, you need to treat approximately 40 people for 5 years to prevent 1 heart attack and 85 people to prevent 1 death)

When presented like that, it should certainly temper the enthusiasm for statin therapy. Again, it may still be the right choice for some people, but given the potential risks and side effects, I would hope for a much greater benefit.

Better Than Statins

A common response is that statins are “the best we have to offer” to reduce one’s risk of cardiovascular disease.  If you are talking about a drug manufactured in a laboratory, then that would be correct. But what else are options?

It turns out following a Mediterranean eating pattern with vegetables, fruit, fish, legumes, and lots of nuts, olive oil and avocados reduces the risk of cardiovascular events as well. For something as simple as nutritional choices the benefit must be much less than a statin, right?

That is what the drug companies would want you to believe. In reality, you need to “treat” 61 people with the Mediterranean diet for 5 years to reduce 1 cardiovascular event (a “combined endpoint” of stroke, heart attack or death).

To be fair, you cannot compare one trial to another as they have very different populations studied, and the outcome measures are different. So, it is not scientifically fair to say, “The Mediterranean diet has been proven to be more beneficial that statins.”  That would require a head-to-head trial. Unfortunately, that trial is unlikely to ever happen.

But it makes for an obvious answer when asked “If statins aren’t all that helpful, what else can I do to reduce my risk of cardiovascular disease?

• Follow a real food, vegetable-based, Mediterranean style diet, low in sugar and high in healthy fats.
• Maintain a physically active lifestyle.
• Exercise with some form of moderate cardio exercise, resistance training and higher intensity interval exercises.
• Practice stress reduction techniques.
• Don’t smoke.
• Manage your other risk factors such as diabetes and high blood pressure.

If you can follow these healthy lifestyle principles, you will be doing far more for your health than any pill you could take. And the best part? The only side effects are having more energy, feeling more empowered, and reducing your risk for chronic diseases.  Sounds like a good trade off to me!

Are you interested in trying a Low Carb-High Fat/Ketogenic lifestyle? If so, great.

Are you looking to your doctor for support in this diet? If so, tread gently.

The medical community has engrained false beliefs that LCHF lifestyle is dangerous to your health. We can blame it on Ancel Keys. We can blame it on an over emphasis on LDL-C. We can blame it on Big Pharma. We can even blame it on the rain!  Whatever the reason, you may not get a warm and receptive response from your physician.

But there is hope. Here are my top 6 Tips on How to Talk to Your Doctor About The LCHF/Keto Lifestyle.

1.    First, ask for your doctor’s opinion about LCHF

Doctors are people too. How would your spouse react if you said, “I’m no longer taking out the trash/doing the dishes/making dinner. It doesn’t work with my personal philosophy of house chores and we are going to change this. Now.” I hope you have a comfortable couch, cause that’s where you will be sleeping.

Picture instead, “Hi Honey. I was thinking that we may want to reassign some of our house chores to help things get done better and more efficiently without putting too much strain on either of us. What do you think about that? Do you have any thoughts how you would like to change things?” That sounds better, right?

The same approach applies to your doctor. Just don’t start by calling your doctor honey. That’s just awkward. Don’t say, “Hey Doc, I’m going LCHF and need you to order x, y and z blood tests on me now and again in 6 months, and help me get off my meds.” Instead, try a kinder, gentler approach. “Hi Doc. I was thinking of ways to be more proactive about my health. What I have done thus far has not worked as well as I have liked. I have heard a lot about LCHF as a way to lose weight, reduce insulin levels, improve blood glucose control, and feel better. I was thinking of trying it. What do you think about that?” You may not immediately get the answer you want (for instance, I am still taking out the trash every week), but you have opened the lines of communication in a much less confrontational way, which can set you up for success as we discuss other tips below.

2.    Measure the effects of Keto on your body with a medical trial

If your doctor is hesitant about you trying LCHF/Keto, suggest a 3- or 6- month trial. Establish what you want to monitor (here’s an eBook I created to help you get started: 10+Medical Tests to Follow on the LCHF Diet). Check what you would like to monitor at baseline and then at the 3-6-month mark. Emphasize you want to experiment to see how your body responds, and that you want his/her expertise in helping analyze the labs to help you progress safely.

Also, if you are on medications for blood pressure, blood sugar or lipids, you will want their guidance with these. Emphasize how you want him or her on your team to help you on your journey and temporary experiment. It is hard to resist when someone genuinely wants your help and thinks you can play a role in their improvement!

3.    Show them your results!

Don’t gloat, don’t brag, but make sure you follow up with your doctor and tell them everything you feel and have measured. Do you have more energy? Less stiffness or inflammation? Are your pants fitting looser? And of course, follow up on all the labs to look at the whole picture. You will be surprised how often your doctor will then turn to you and ask you what you have been doing. If they have the time, they will likely say “Tell me more about that.” Yes! This is your opportunity to teach them the power of LCHF/Keto. Then, when the next patient comes around, they won’t be as resistant, and may even start to suggest it themselves. The patient becomes the teacher!

4.    Find a doctor who will listen

Our healthcare system is messy. No question. We don’t always have freedom to choose our own doctors. But that doesn’t mean it is impossible to change. Here is a hint: If your doctor isn’t open minded enough to try a self-directed experiment with you, what else are they close minded about? Maybe it is time for a change anyway.

It may not be easy to find a doctor with an open mind who takes your insurance, is geographically desirable, and who is accepting patients, but there are some tricks you can use. Look for a doctor who has been in practice more than seven years, but less than 20 years. In my experience, this is the critical “open minded” window. They have been in practice long enough to be confident in their own skills and are willing to stray from “what everyone else does.” On the other hand, they have not been in practice so long that “That’s the way I have always done it” becomes the reason for their care.

Look for doctors with interests in prevention, sports medicine, or integrative medicine. These suggest more interest in health and less interest in the standard “pill for every ill” medical practice. Lastly, people are developing lists of Keto-friendly doctors online. While these may be small at present, they are growing quickly and hopefully can help you find the right doctor for you. 

5.    Seek online Keto support

Numerous online sites exist to help you with you transition to a LCHF lifestyle. I have built my blog and Low Carb Cardiologist Podcast to provide information and support on those who are embarking on their healthy lifestyle journeys, with a lot of information about Keto and LCHF.

Some other sites I recommend are DietDoctor.com, 2KetoDudes podcast, and Ketovangelist podcast, to name a few.

6.    Take control of your own healthcare journey

As nice as it is to have your physician on board with your health decisions, it is not always needed. As Brian Williamson from Ketovangelist said to me on his podcast, “If your doctor is more interested in your health than you are, then you are in trouble!” I agree with that sentiment, and I encourage everyone to be the driver in their own healthcare. You can still choose to try the LCHF lifestyle even without your doctor. Look for a reputable second opinion doc who is willing to help open lines of communication between you and your doc. That is one of the services I enjoy providing the most. Since I speak the same language, I can usually help someone start the conversation with their doctor.

In addition, online sites such as WellnessFx.com allow you to get your blood drawn and seek consultations with health care providers (Disclaimer: I am one of those providers and get paid for my services. Another disclaimer: I love doing it). If you go this route, I encourage you to then bring your results back to your doctor (See number 3 above). You can now become the teacher, young Jedi.

There you go. With these six simple tips and resources, you will be well on your way to safely adopting a Keto lifestyle. Doctors are people too. Just like everyone else, we like to be needed, we like to be helpful, and we don’t like being told what to do. I just need to remember that the next time my wife “needs” me to clean the toilet….

What Does My Cholesterol Level Mean?

Depending on how you look at it, cholesterol can be an incredibly simple topic, or an incredibly confusing one. Contemporary medicine teaches that cholesterol is “bad” and should be low. That seems pretty simple, right? Get it tested, if it’s high, start a drug to lower it. 

Times have changed. Now, cholesterol is much more complex, and we all need to be armed with knowledge before we sit down with our doctors to evaluate our cholesterol levels.

Here is my guide to you and your doctor for evaluating your cholesterol.

1. Understand the difference between Total Cholesterol (TC) and high density lipoprotein (HDL) and low density lipoprotein (LDL)

If you doctor is referring to your total cholesterol (TC) and is making decision based on your TC— Run, don’t walk. Run away and find another doctor. TC is comprised of low density lipoprotein (LDL), so-called “bad cholesterol” even though it isn’t bad. High density lipoprotein (HDL), so-called “good cholesterol”, and remnant cholesterol (VLDL and IDL). Initial studies in the 1960s and 70s looked at TC and risk of cardiovascular disease (CVD) and found a weak association.  That was prior to when scientists learned how to measure LDL and HDL.

Studies then looked at the individual lipoproteins (i.e. LDL and HDL) and found the higher the LDL, in general, the higher the risk for CVD. And the higher the HDL< the lower the risk of CVD. So, while talking about TC was cutting edge in the 60s and 70s, it is woefully outdated today. That is why if your doctor is still evaluating and treating TC—Run!

2. Does Your Doctor Know Your TC to HDL and TG to HDL Ratios?

If your doctor does not know your ratios, this is another reason to run away and find another doctor (We are doing lots of running here, bonus exercise!) Studies in the early 2000s and more recently have shown that total cholesterol to HDL ratio (TC:HDL) and triglyceride to HDL ratio (TG:HDL) are BETTER predictors of cardiovascular risk than isolated LDL, TC or HDL.

By incorporating TG and HDL into the analysis, these ratios incorporate the impact of remnant cholesterol and track with insulin resistance, both strong predictors of CVD. These ratios are calculated from a standard lipid profile, so they do not require any special testing or special labs. They are widely available for everyone to see. So if your doctor is not using them to evaluate your lipids, it’s time to find a new one.

3. Understanding a Familial hypercholesterolemia (FH) diagnosis

Familial hypercholesterolemia (FH) is a diagnosis that requires (wait for it…) a family history! As the name suggests, it is an inherited condition passed from generation to generation. All too often, doctors will see an LDL level over 190 and make the diagnosis of FH. If your doctor makes that diagnosis that based on level alone without a family history, run!

There is a well-accepted scoring system, The Simon Broome Criteria, to help determine if someone has FH. This equation factors in age of diagnosis, absolute level of LDL, in addition to family history of early onset hyperlipidemia or early onset heart disease. It makes a big difference if you have FH or not. Don’t let your doctor label you as having FH without applying the full criteria. Just wait for the look on their face when you respond, “What was my Broome score? Did it confirm I have FH?” and hope you don’t hear crickets.

4. What is Advance Lipid Testing?

Advance lipid testing may be helpful. And it may not. Advanced lipid testing can tell us the size, density, and inflammatory characteristics of our lipoproteins. This can help further risk stratify the potential danger of our lipids. For instance, small, dense LDL tend to correlate more strongly with CVD, whereas so-called pattern A LDL (the larger, less dense version) does not correlate as well.

Here is the interesting part. Those with high TG and low HDL almost uniformly have small dense LDL and increased inflammation. Conversely, those with low TGs and high HDL have Pattern A, larger less dense LDL. Are you starting to see a pattern? Low TG and high HDL=good. High TG and low HDL=bad.

Sometimes, however, there can be variation in this equation. Therefore, I usually suggest people get advanced lipid testing one time to see if their results correlate. If they do, then you can just follow your ratios to predict your advanced results. Why not get them all the time? They are frequently not covered by insurance and can be expensive.

5. Interpret your lipids in context

Lipids don’t exist in a vacuum. They exist in your body, so it’s important to take into account what else is going on in your body. Insulin resistance and inflammation can directly affect your lipids and increase your risk in general. Hypertension, obesity, and family history of heart disease also play crucial roles in determining your risk.

Therefore, if your doctor checks only your lipids and bases decision on those labs alone—Run! Instead, you should get a hsCRP, Hgb A1c, fasting glucose, insulin and HOMA-IR, BP measurement, family history assessment, and complete history. This is the context in which your lipids should be evaluated. Not alone in a vacuum.

6. Why test a risk factor that may be related to CVD risk when you can test the disease itself?

Good question, right? To truly know what your lipids mean to you, you also need to know if you have evidence of CVD. Coronary artery calcium scores and Carotid Intima Media Thickness (CIMT) are two easy, relatively inexpensive tests, that you can get to show you whether or not you have current evidence of CVD. The presence or absence of disease significantly impacts the risk of lipid levels.

So, What Does Your Cholesterol mean to You? It depends.

It depends on many factors, and only by evaluating ALL of those factors can you truly know what impact your lipids may be having on our health. Anything short of this evaluation is an inadequate and antiquated approach to lipids.

Now you are forewarned and forearmed, and you can walk into your doctor’s office ready to ask the important questions and help guide the workup so that you can know what your cholesterol means to you.

Thanks for reading, and as always, please let us know If you have any comments or questions.

Don’t look now, but the updated clinical practice cholesterol guidelines from the American College of Cardiology, the American Heart Association and others are getting personal. Although the guidelines still contain their familiar approach — that I consider too aggressive with drug therapy — the latest 2018 version of the guidelines now includes an impressive update to emphasize lifestyle intervention, plus a more individualized approach for risk assessment.

MedPage Today: AHA: Revised Lipid Guide Boosts PCSK9s, Coronary Calcium Scans

Could this be the start of a progressive trend away from shotgun statin prescriptions? I sure hope so.

Prior guidelines emphasized the 10-year ASCVD risk calculator as the main determining factor for statin therapy. In the 2018 update, the guidelines acknowledge that the calculator frequently overestimates the risk in those individuals who are more involved with prevention and screening. (In other words, those patients more interested in and proactive about their health; I find many in the low-carb world fall into this category.)

The ensuing discussion with a healthcare provider should then focus on:

[T]he burden and severity of CVD risk factors, control of those other risk factors, the presence of risk-enhancing conditions, adherence to healthy lifestyle recommendations, the potential for ASCVD risk-reduction benefits from statins and antihypertensive drug therapy, and the potential for adverse effects and drug–drug interactions, as well as patient preferences regarding the use of medications for primary prevention… and the countervailing issues of the desire to avoid “medicalization” of preventable conditions and the burden or disutility of taking daily (or more frequent) medications.

I appreciate the attention the new guidelines bring to the depth of the discussion that should ensue between doctor and patient. Considering the treatment burden is equally as important as the burden of disease, and possibly even more important in patients who have not been diagnosed with heart disease, these individualized discussions about trade-offs are critical to personalized care.

Also worthy of mention is the increased use of coronary artery calcium scores (CAC) to help individualize risk stratification. The updated guidelines specify CAC may be useful for those age 40-75 with an intermediate 10-year calculated risk of 7.5%-20%, who after discussion with their physician are unsure about statin therapy. They specify that a CAC of zero would suggest a much lower risk than that calculated by the ASCVD risk formula, and thus take statins off the table as a beneficial treatment option.

This is huge. I cheered when I read this! I have been critical of prior guidelines that focused on ways to find more people to place on statins. The mention of finding individuals unlikely to benefit from statins is a giant step in the right direction.

The guidelines go even further: they mention that a CAC either over 100 or greater than the 75th percentile for age increases the CVD risk and the likely benefit of a statin. A CAC between 1-99 and less than the 75th percentile does not affect the risk calculation much and it may be worth following the CAC in five years in the absence of drug therapy. I would still argue that a CAC >100 does not automatically equal a statin prescription and we need to interpret it in context, but I greatly appreciate this attempt at a more personalized approach.

The guidelines also go beyond the limited risk factors included in the ASCVD calculator by introducing “risk modifying factors” such as:

• Premature family history of CVD
• Metabolic syndrome
• Chronic kidney disease
• Chronic inflammatory conditions such as rheumatoid arthritis and psoriasis
• Elevated CRP > 2.0 mg/L
• Elevated Lp(a) > 50 mg/dL or 125 nmol/L
• Elevated triglycerides > 175 mg/dL

Although they use these criteria to define an increased risk, the opposite would likely hold true. An absence of those criteria could define a lower risk situation.

Some changes deserve mention from a controversy standpoint as well. For instance, the new guidelines recommend checking lipid levels as early as two years old in some circumstances. Two!

They also recommend statin therapy for just about everyone with diabetes with no mention of attempting to reverse diabetes before starting a statin, a drug that has been shown to worsen diabetes and insulin resistance. In addition, the new guidelines do not mention the likely discordance between LDL-C and LDL-P in those with diabetes.

Last, the new guidelines define an LDL-C > 190 mg/dL as an absolute indication for statin therapy with a treatment goal of 190 mg/dL is in familial hypercholesterolemia populations (and even then has heterogenous outcomes). There is a clear lack of data supporting that same recommendation for metabolically healthy individuals with no other cardiac risk factors and no other characteristics of familial hypercholesterolemia. This is a clear example of when a guideline turns from “evidence based” to “opinion based.”

In summary, the guideline committee deserves recognition for its emphasis on an individualized care approach, its use of CAC, and its broader description of discussing potential drawbacks of drug treatment. It still combines opinion with evidence and believes all elevated LDL is concerning, but I for one hope it will continue its progression away from generalizations and someday soon see that individual risk variations exist, even at elevated LDL-C levels.

The consultation was well worth my time and money! Loved his approach so much that my husband and I have decided to work with him long distance.
