In the fall of 2018, I was diagnosed with Type 2 Diabetes. I was educated enough to know that there was something I could do about it and set out to change the path I was on by adopting a low carbohydrate/Ketogenic Diet to control my blood sugars. Fortunately, it worked right away- but soon after I discovered that I had some red flags on my cholesterol test results. There is a history of Cardiovascular disease in my family and I was disappointed that I might have to yet again make diet changes but was willing to do what was best for my whole health. After an appointment with a local Cardiologist, I felt somewhat confused about how to move forward. I wanted more information and not just a prescription.

I contacted Dr. Scher for a consult because I wanted to confer with someone who not only understood my condition but who could also give me the latest and soundest advice on how I might treat it and move forward in the best way for me as an individual- not as a statistic. I needed someone who came from a low carb perspective as well as a medical background. My interaction with him was positive, informative and went a long way to making me feel like I could make informed choices without the black and white thinking of well-meaning physicians. He sees the WHOLE person and not just one aspect of their health. Wellness is a journey- and having Dr. Scher along the way is a great way to make the trip!

Dr. Scher’s one-on-one Consultation was extremely valuable in my search for advice about cardiovascular health on a low-carb diet. During our discussion, I learned that interpreting lab results using the standard reference ranges can be misleading for anyone on low-carb or keto. He helped me better understand my test results and develop effective strategies to improve my cardiovascular health through nutrition and exercise. Dr. Scher is a good listener and a pleasure to work with. He is an excellent preventive cardiologist with a deep understanding of lipidology and metabolism, and the issues and challenges specific to a low-carb lifestyle.

We hear the words Heart Healthy a lot, especially when it comes to our nutrition.

By now, you’re likely used to seeing cereals with the “heart healthy” moniker. Is it really heart healthy? We all too frequently refer to foods as “heart healthy”, or we say that our doctor gave our hearts a “healthy” checkup.  

It all sounds nice. But what does it mean? How do we define heart health?

How does LDL Cholesterol affect Heart Health?

Unfortunately, most of our current definitions center around LDL cholesterol concentration.  While LDL cholesterol plays a role in heart health, it by no means defines heart health in totality.

In fact, in many cases it is the least important factor.

Our healthcare system has simplified things too much, so as a result we focus on one bad guy, one demon to fight. In reality heart disease is caused, and made more likely to occur, by a constellation of contributing issues.

Elevated blood sugar, elevated insulin levels, inflammation, high blood pressure, poor nutrition, and yes, lipids all contribute to heart health.  It does us all an injustice to over simplify it to one single cause.

What food is heart healthy?

Our superficial definition of cardiac risk is how industrial seed oils containing polyunsaturated fatty acids (PUFAs) became known as “heart healthy.”

Studies show that they can lower LDL. But they can also increase inflammation and have no clinical benefit and even increase risk of dying. According to our simplified definitions, that doesn’t stop them from being defined as “heart healthy.”

 That’s right! Something that increases our risk of dying is still termed “heart healthy.”  How’s that for a backwards medical system?!

Same for blood sugar. If you have a diagnosis of Type 2 Diabetes (DM2) that is a risk for cardiovascular disease. If you don’t have the diagnosis, you are fine. That ignores the disease of insulin resistance that can predate diabetes for decades and increases the risk of heart disease and possibly even cancer and dementia.

Cereal can also be called “heart healthy” as they may minimally lower LDL. But is that a good thing if they contain grains that also worsen your insulin resistance and metabolic syndrome? I say definitely not.

Time has come to stop this basic, simplified evaluation and start looking at the whole picture.

How Low Carb High Fat Diets Improve Heart Health

Low carb high fat diets have been vilified as they can increase LDL. But the fact of the matter is that it does so only in a minority of people. The truth is that they can improve everything else!

These diets reduce blood pressure, reduce inflammation, improve HDL and triglycerides, and reverse diabetes and metabolic syndrome! Shouldn’t that be the definition of “heart healthy” we seek? Instead of focusing on one isolated marker, shouldn’t we define heart health by looking at the whole patient?

Only by opening our eyes and seeing the whole picture of heart healthy lifestyles can we truly make an impact on our cardiovascular risk and achieve the health we deserve.

Join me in demanding more. Demand better.

Is the Keto Diet Heart Healthy? 7 Reasons Why This Cardiologist Agrees

I am a board certified, card-carrying cardiologist, and I want my clients to eat more fat, more meat, more cheese, more eggs, more avocado, more, more, more.

For decades medical establishments have convinced us to eat low fat, higher carb diets. How has that worked for our health? Here’s a hint, we have record numbers of obesity, diabetes and dementia. Yet, as a cardiologist, that’s the party line I am supposed to support.

But I can’t. It’s just wrong, and I can’t support that line of thinking, not for a second.

Instead, I am a Low Carb Cardiologist. Here are the top Seven reasons why

1. Reducing Insulin is Essential to Health and Weight Loss.
   Insulin is a hormone naturally secreted by the pancreas to help regulate blood sugar levels. Everything we eat (except possibly for 100% fat meals) causes insulin to rise. That is normal physiology. The problem occurs when our bodies become resistant to the effects of insulin, thus requiring our pancreas to make more and more and more insulin.The problem? Insulin promotes fat storage, increase inflammation and oxidation, and can even help fuel the growth of cancer cells. Therefore, the healthiest approach is one which reduced the level of insulin to the lowest possible levels. As it happens, a Low-carb High-fat or ketogenic lifestyle (LCHF/Keto lifestyle) dramatically improves your body’s sensitivity to insulin, reduces the amount of insulin secreted, and it allows your body to naturally use your fat stores for what they are designed for: Break them down into energy! Once we see that we need to fight chronic elevations of insulin, it becomes obvious why a low-fat diet is harmful, and why a low carb diet is the true path to health.
   
2. Eating Fat Improves Your Cholesterol!
   Wait, what? Eating fat can improve my cholesterol? Sounds crazy, right? That goes against everything we have heard from the medical establishment. Notice I said “cholesterol.” I didn’t say the “bad” low density lipoprotein (LDL), I didn’t say the “good” high density lipoprotein (HDL), or any one specific type of cholesterol. We have over emphasized the solitary variable of LDL for too long. Total cholesterol to HDL ratio, Triglyceride to HDL ratio, lipoprotein size and density, insulin sensitivity, and other metabolic measures are more powerful predictors of cardiovascular health than just LDL.Once again, we see that all these markers improve with a Low Carb High Fat (LCHF) lifestyle. The medical establishment needs to realize that we are more complicated than one lab value. The key is to look at the whole picture, and this picture dramatically improves with a LCHF lifestyle.If you want to learn more about lipids and cholesterol, I recommend checking out my new dedicated cholesterol course: The Truth About Lipids.
3. Higher HDL is Associated with a Lower Risk of Heart Disease.
   HDL is your friend, but drugs are not. Observational evidence has consistently shown that higher HDL is associated with a lower risk of cardiovascular disease. However, our healthcare establishment does not prioritize HDL for one simple reason- Drugs that raise HDL don’t make you healthier. Trial after trial has failed to show any benefit from drugs that significantly increase HDL.Instead, it’s the HDL-raising lifestyle that provides the benefit, not artificially increasing it with drugs. What’s the best lifestyle to naturally raise HDL? You guessed it. LCHF/Keto lifestyle. Add in some resistance training and you have your friendly HDL climbing the way it was meant to…Naturally.
4. LCHF Leaves You Feeling Great, Leading to Healthier Decisions
   What kind of health decisions do you make when you are fatigued, achy, and find it difficult to concentrate? That’s a rhetorical question, I already know the answer. When things look glum and we don’t feel well, it’s far too easy to sit on the couch or reach for the chips and cookies. Compare those decisions to those you make when you are well rested, energetic, and seeing the world more clearly. For most people, the better you feel, the better decisions you make.Guess what? The majority of people who change to a LCHF lifestyle feel better! It may take a few days or weeks, but in general, they feel more in control of their health, more energetic, and they are able to make better health decisions. I admit this is difficult to prove in a scientific trial. That is why we all should become our own n=1 scientific trial. How do you feel and how are your health decisions after going to a LCHF lifestyle? What matters most is what works for you, not what works for hundreds of people who are kinda-sorta like you.
5. Keto helps you with fasting.
   Eating better helps you not eat. People who eat a high carb diet eat a lot, don’t they? They are always grazing and snacking. Our bodies go through the roller coaster of blood sugar and insulin spikes, making it a challenge to go 24, 18, or even 6 hours without eating. This creates a constant, unwavering supply of insulin in our blood stream.Why is this harmful? For one, it promotes fat storage and keeps us from using our fat as fuel. Secondly, chronically elevated insulin can predispose to heart disease, strokes, cancer, dementia and other devastating health conditions. When people change to Keto, however, they realize they do not need to eat nearly as much or as frequently. Avoiding the carbs and increasing the fats keeps us full longer, and our bodies quickly adapt to longer periods without eating. The result? We can use our fat stores for what they were designed- a source of fuel! It also allows our body to maintain lower insulin levels, and also allows our cells to take care of their health chores, referred to as Autophagy.If you’re interested in Fasting and want to make sure you’re doing it correctly, download my free Full Guide to Fasting.
6. LCHF Promotes Health Through Increased Autophagy.
   Autopha-What? In medicine we like using fancy words to make us look smart. Autophagy is a big word to describe cellular housekeeping. When we have low enough intake of carbs and protein, or when we do intermittent fasts, our bodies can take care of their “to do” lists.  That list includes breaking down weak or damaged cells, recycling the good parts and discarding the rest, and slowing down the processes that can lead to abnormal cell growth (i.e. excess proteins in Alzheimer’s disease, abnormal cancer cells etc.).Admittedly, long term outcome studies evaluating fasting or LCHF and cancer or dementia risk have not been done. But, on the flip side, drug trials to prevent the same are showing no benefit despite hundreds of millions of dollars invested. If you asked me (which you sort of did since you are reading my article), I’d vote for autophagy as a preventative strategy any day. It makes good physiologic sense, and it is so easy to achieve.
7. With Keto You Will Enjoy Eating Again!
   That’s right. A way of eating that helps you lose weight, helps you feel better, improves your health and is actually enjoyable! No fake processed soy products, no cardboard tasting rice cakes. True, it also means no more candy, processed snack foods, doughnuts and danishes. But once you swear them off for a few weeks, and you are eating all the eggs, avocados, nuts, fish, steak, cheese etc. that you want, you won’t miss those old crutches any more. Let the enjoyment begin!

I could go on, but since it seems people like “7 Reason” articles, I will leave it at that. 

Now you know the secret: Look at the whole picture. Look for a lifestyle, (not a diet) that helps you feel better, increases your enjoyment, and still benefits your overall health.

ADDENDUM!!

Since I have published this article, there has been a windfall of media buzz around low carb diets increasing our risk of heart disease or diabetes. Let’s look at where that information came from.

1- A study force feeding mice excessive amounts of industrial omega 6 oils. You can guess what I have to say about that. The article was incredibly helpful, and I immediately stopped force feeding my pet mice industrial seed oils. Thanks goodness for that article. As for how it applies to humans eating real food that contain fat, there is zero correlation.

2- Epidemiological study suggesting those who ate low carb (40% calories from carbs, which by the way is NOT low carb) as measured by two food journals over 25 years had a higher risk of dying. Oh and by the way, at baseline they were heavier, more sedentary, smoked more, and ate fewer veggies. Yet somehow they concluded it must be the low carb diet that “caused” the harm. Once again, it may not be bad science, but it sure was awful interpretation of the science.

In light of those two studies and the hoopla surrounding them, has anything happened to change my mind about a LCHF/keto diet being beneficial for our overall health and our heart health?

Absolutely not.

We still need to individualize our care and our lifestyle for who we are and how our bodies respond. That is always the case regardless of our nutrition, our medications, our exercise etc. As long as we do that, then this cardiologist still believes that LCHF IS HEART HEALTHY!

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!
