Are Statins Dangerous?

Author:  Dr. Stephen Chaney

 

statins side effectsSeveral years ago I recall a cardiologist telling my class of first year medical students that statins were so beneficial that we should just put them in the water supply. He said it in a lighthearted manner, but I think he really believed it. [In actuality, statin drugs are so widely prescribed that they already are in the water supply of some major US cities (http://usatoday30.usatoday.com/news/nation/2008-03-10-drugs-tap-water_N.htm).]

The Pros And Cons of Statins

When taken by people who have already had a heart attack, statins clearly save lives. However, as I documented in my eBook “The Myths of the Naysayers” (scroll down to Check It Out if you would like to learn how you can get that eBook for FREE) the benefits of statins are marginal at best in healthy people who have not yet had a heart attack.  So are statins one of the risk factors for diabetes?

Statin Side Effects

In addition, statins have some significant side effects. For example, up to 5% of people taking statins develop muscle pain. For most people the muscle pain is merely an inconvenience, but in a small percentage of cases it can lead to fatal complications.

More concerning are the required label warnings that statins can lead to memory loss, mental confusion, high blood sugar and type 2 diabetes. In other words, they may not kill you, but they sure can make life miserable.

Because of the marginal benefits in healthy people and the multiple side effects, some experts are starting to step up and say that statins may be overprescribed. For example, Dr. Roger Blumenthal, MD, a professor and director of the Ciccarone Preventive Cardiology Center at Johns Hopkins recently said: “Statin therapy should not be approached like diet and exercise as a broadly based solution for preventing coronary heart disease. These are lifelong medications with potential, although rare, side effects, and physicians should only consider their use for those patients at greatest risk…”

Dr. Blumenthal made that statement a few years ago when we thought that statins only increased diabetes risk by 9-22%. The latest study suggests that statins may increase diabetes risk by as much as 46%. That, in my opinion, is a game changer.

Statins And Diabetes Risk?

statins and diabetes riskThe idea that statins increase the risk of type 2 diabetes is not new. Previous studies have reported that statins increase the risk of diabetes anywhere from 9% to 22%. As a consequence, the FDA required that “increased risk of elevated blood sugar and developing type 2 diabetes” be added to the warning label on statin drugs starting in 2012.

The authors of the current study (Cederberg et al., Diabetologia, DOI 10.1007/s00125-015-3528-5) felt that previous studies may have underestimated the true risk of developing diabetes because:

  • Previous studies were often done with patient populations at very high risk of cardiovascular disease. In today’s world statin drugs are often prescribed for patients at moderate or low risk of cardiovascular disease. The authors felt that the effect of statins on diabetes risk might not be the same in these two populations.
  • Previous studies relied on self-reported diabetes or fasting blood glucose levels as the criteria for classifying the study subjects as diabetic. In today’s world there are a wider array of diagnostic tests that are used to confirm a diagnosis of diabetes.

This study looked at the risk of developing type 2 diabetes associated with statin treatment over a 6-year period in a group of 8,749 Finnish men (aged 45-73 years) who were enrolled in the Metabolic Syndrome in Men (METSIM) study. That means that the men had metabolic syndrome (they were pre-diabetic), but none of them were yet diabetic at the beginning of the study. Other important characteristics of the study were:

  • This was a healthy cross-section of the Finnish population. Only 24.5% of the study participants were using statin drugs.
  • The diagnosis of diabetes was based on multiple criteria: fasting blood glucose levels, an oral glucose tolerance test, and hemoglobin A1c (a measure of blood sugar control over the last 6 weeks).

As you might suspect, the increased risk of developing diabetes during the 6-year trial was greatest for those who were older, more obese, less physically active and had more advanced metabolic syndrome at the beginning of the study. What was surprising, however, were the other conclusions of the study.

  • Statin treatment increased the risk of developing type 2 diabetes by 46%, and the increased risk of developing diabetes directly correlated with the dose of the statin drug.
  • Insulin sensitivity was decreased by 24% and insulin secretion was decreased by 12% in individuals on statin treatment. In layman’s terms that means the pancreas was 12% less able to release insulin and tissues in the body were 24% less able to respond to insulin. That’s a double whammy!

Even though this study is a significant improvement over previous studies, it does have some limitations of its own.

  • The study population was exclusively white, Finnish men. The conclusions may not apply to other population groups.
  • Simvastin (Zocor) and atorvastatin (Lipitor) were the most widely used statin drugs in this study (84% of the study participants taking statins were on one of these two drugs). These two statins clearly increased the risk of developing diabetes in a dose-dependent manner. There were not enough subjects on the other statin drugs to evaluate their effect on diabetes risk, but previous studies have suggested that other statins may be less prone to increase diabetes risk.

Should You Take Statins If you are Diabetic or Pre-Diabetic?

statins and diabetesLet’s start by identifying the symptoms of metabolic syndrome or pre-diabetes. They are:

 

  • Abdominal obesity (waist size of greater than 35” for women & 40” for men)
  • Slightly elevated triglycerides (greater than 150 mg/dl)
  • Low HDL cholesterol (less than 50 mg/dl for women and 40 mg/dl for men)
  • Slightly elevated blood pressure (greater than 130/85
  • Slightly elevated blood sugar (greater than 100 mg/dl fasting blood glucose)

If you have three or more of these symptoms, you likely have metabolic syndrome or pre-diabetes.

The medical profession and the pharmaceutical industry are circling their wagons and assuring us that the benefits of taking statins clearly outweigh the risks – even if you are diabetic or pre-diabetic. I’m not so sure

The problem is that the benefits of statin therapy in healthy individuals who have not had a heart attack are modest at best. This sets up a real “Catch 22” situation. Diabetes and pre-diabetes increase the risk of heart disease, so current guidelines recommend that statin drugs should be prescribed for individuals who are pre-diabetic or diabetic. However, we now know that those very same statin drugs increase the risk of you becoming diabetic if you are already pre-diabetic. Because they decrease insulin production and increase insulin resistance they may also make your diabetes worse if you are already diabetic, but that has not been directly tested.

That is concerning because diabetes can lead to very serious complications such as neuropathy (numbness in the extremities), kidney disease & kidney failure, high blood pressure and stroke, and cataracts & glaucoma. Of course, you can always use diabetes medications to counteract the diabetes-enhancing effect of the statins, but those medications also have serious side effects. The pharmaceutical merry-go-round continues!

Are There Alternatives For Reducing the Risk Of Heart Disease?

alternative is eat healthyIf statins are only modestly effective at reducing the risk of heart disease in otherwise healthy individuals and they significantly increase the risk of developing diabetes, it is perhaps prudent to ask whether there are alternative, non-drug approaches that can significantly reduce your cholesterol levels and allow you to avoid statins altogether?

According to the National Heart Lung & Blood Institute the answer to that question is a resounding yes! They call it Therapeutic Lifestyle Change or TLC (http://www.nhlbi.nih.gov/health/resources/heart/cholesterol-tlc). The TLC recommendations are:

  • Eat less than 7 percent of your daily calories from saturated fat
  • Eat less than 200 mg a day of cholesterol
  • Get only 25–35 percent of daily calories from total fat (this includes saturated fat calories)
  • Other diet options you can use for more LDL lowering are:
    • Add 2 grams per day of plant stanols or sterols
    • Add 10–25 grams per day of soluble fiber
  • Consume only enough calories to reach or maintain a healthy weight
  • In addition, you should get at least 30 minutes of a moderate intensity physical activity, such as brisk walking, on most, and preferably all, days of the week.

The NHLB Institute recommends that the TLC approach always be tried first, and that statins only be used if the lifestyle approach fails – a message that seems to have gotten lost in the translation in many doctor’s offices.

I have also discussed some natural alternatives in my previous articles such as “Does An Apple A Day Keep Statins Away?” (https://healthtipsfromtheprofessor.com/apple-day-keep-statins-away/) and “Is Fish Oil Really Snake Oil?” (https://healthtipsfromtheprofessor.com/fish-oil-really-snake-oil/).

What Should You Do?

Perhaps it is time to have a serious discussion with your doctor about following the National, Heart Blood & Ling Institute’s TLC recommendations – either as an alternative to statins or as something that will allow your doctor to reduce the amount of statins that your need to take.

I also recommend that you make lots of fresh fruits and vegetables and either oily fish or fish oil supplements part of your regular diet.

The old professor is just like the rest of you. My cholesterol gets a bit high from time to time and my doctor suggests going on a statin. Instead I ramp up my exercise, watch what I eat a bit more carefully, and use a supplementation program that includes stanols, sterols and omega-3 fatty acids.

My cholesterol gets back to where it is supposed to be. My doctor is happy, and I am happy.

 

The Bottom Line

  • The news about statin drugs keeps getting worse. Not only are they only marginally effective in healthy people who have not yet had a heart attack, but the latest study suggests that they may increase the risk of developing diabetes by up to 46%.
  • That is concerning because the complications of diabetes can be quite serious, and diabetes drugs have side effects of their own.
  • In addition to the TLC program I recommend lots of fresh fruits and vegetables, oily fish or fish oil supplements, and a supplement that provides the TLC-recommended 2,000 mg of plant stanols and sterols.

If you have been prescribed statin drugs, it may be time to make a serious commitment to the TLC lifestyle change and have a discussion with your physician about reducing or eliminating your statins. This is especially true if you are already pre-diabetic or diabetic.

      Dear Doreen,
      I don’t mind you using my health tips as long as you acknowledge the source and do not change the content. Something as simple as leaving a few words or a sentence out can sometimes substantially alter the meaning.

    Excellent article and worthy of being read by all. As a cancer survivor of 17 years I wish the mainstream media would print articles like this on a regular basis – we are not told the facts by the media – they are afraid of losing revenue from advertising. Would the government (us) ever provide this information – only in a place that no consumer ever goes to. We need more good articles like this.

    I remember my mother calling to say she had been 2 weeks in hospital due to overdose. In questioning her, I found the SAME doctor had her on 14 meds. I called him direct and told him no way, Jose, and he then reduced her to two and finally to one. As a health consultant, I find it insulting that Big Pharma has such control of doctors, etc. As a health consultant and acupuncturist, it makes me even madder and sadder because Western Medicine is not well informed on so many health issues, i.e., hormones, or even the fact that for over 3 years we have known that the older patients (55+) need to have their BP at 140/90 to get blood to their heads to avoid imbalance, headaches, poor memory, dizziness and/or vertigo, while in Chinese medicine this is known as blood def. and we take care of it. Every medicine is a possible danger in one way or another, but combining them is pure stupidity and to me, homicide if not suicide of a patient.

    ….and may I add that if you have senior parents, it is essential that you advocate for them. When my Dad was on 9 with an optional 2, and I “demanded” after passing out 3 times that they pick the (2) that would benefit him and get rid of the rest for a while the DR reluctantly went along with it because I was just adamant. 10 days later, We meet with the physician and he outwardly says to me, ” you know, I actually see that your Dad is doing better…. this really surprises me because i thought the medications were benefiting him and I thought I would be proving a point that he needed them” WOW! He’s only on 3 today…and he’s doing so much better. Be a voice for those you love… you might save their life.

High Protein Diets and Weight Loss

Posted October 16, 2018 by Dr. Steve Chaney

Do High Protein Diets Reduce Fat And Preserve Muscle?

Author: Dr. Stephen Chaney

Healthy Diet food group, proteins, include meat (chicken or turkAre high protein diets your secret to healthy weight loss? There are lots of diets out there – high fat, low fat, Paleolithic, blood type, exotic juices, magic pills and potions. But recently, high protein diets are getting a lot of press. The word is that they preserve muscle mass and preferentially decrease fat mass.

If high protein diets actually did that, it would be huge because:

  • It’s the fat – not the pounds – that causes most of the health problems.
  • Muscle burns more calories than fat, so preserving muscle mass helps keep your metabolic rate high without dangerous herbs or stimulants – and keeping your metabolic rate high helps prevent both the plateau and yo-yo (weight regain) characteristic of so many diets.
  • When you lose fat and retain muscle you are reshaping your body – and that’s why most people are dieting to begin with.

So let’s look more carefully at the recent study that has been generating all the headlines (Pasiakos et al, The FASEB Journal, 27: 3837-3847, 2013).

The Study Design:

This was a randomized control study with 39 young (21), healthy and fit men and women who were only borderline overweight (BMI = 25). These volunteers were put on a 21 day weight loss program in which calories were reduced by 30% and exercise was increased by 10%. They were divided into 3 groups:

  • One group was assigned a diet containing the RDA for protein (about 14% of calories in this study design).
  • The second group’s diet contained 2X the RDA for protein (28% of calories)
  • The third group’s diet contained 3X the RDA for protein (42% of calories)

In the RDA protein group carbohydrate was 56% of calories, and fat was 30% of calories. In the other two groups the carbohydrate and fat content of the diets was decreased proportionally.

Feet_On_ScaleWhat Did The Study Show?

  • Weight loss (7 pounds in 21 days) was the same on all 3 diets.
  • The high protein (28% and 42%) diets caused almost 2X more fat loss (5 pounds versus 2.8 pounds) than the diet supplying the RDA amount of protein.
  • The high protein (28% and 42%) diets caused 2X less muscle loss (2.1 pounds versus 4.2 pounds) than the diet supplying the RDA amount of protein.
  • In case you didn’t notice, there was no difference in overall results between the 28% (2X the RDA) and 42% (3X the RDA) diets.

Pros And Cons Of The Study:

  • The con is fairly obvious. The participants in this study were all young, healthy and were not seriously overweight. If this were the only study of this type one might seriously question whether the results were applicable to middle aged, overweight coach potatoes. However, there have been several other studies with older, more overweight volunteers that have come to the same conclusion – namely that high protein diets preserve muscle mass and enhance fat loss.
  • The value of this study is that it defines for the first time the upper limit for how much protein is required to preserve muscle mass in a weight loss regimen. 28% of calories is sufficient, and there appear to be no benefit from increasing protein further. I would add the caveat that there are studies suggesting that protein requirements for preserving muscle mass may be greater in adults 50 and older.

The Bottom Line:

1)    Forget the high fat diets, low fat diets, pills and potions. High protein diets (~2X the RDA or 28% of calories) do appear to be the safest, most effective way to preserve muscle mass and enhance fat loss in a weight loss regimen.

2)     That’s not a lot of protein, by the way. The average American consumes almost 2X the RDA for protein on a daily basis. However, it is significantly more protein than the average American consumes when they are trying to lose weight. Salads and carrot sticks are great diet foods, but they don’t contain much protein.

3)     Higher protein intake does not appear to offer any additional benefit – at least in young adults.

4)     Not all high protein diets are created equal. What some people call high protein diets are laden with saturated fats or devoid of carbohydrate. The diet in this study, which is what I recommend, had 43% healthy carbohydrates and 30% healthy fats.

5)    These diets were designed to give 7 pounds of weight loss in 21 days – which is what the experts recommend. There are diets out there promising faster weight loss but they severely restrict calories and/or rely heavily on stimulants, they do not preserve muscle mass, and they often are not safe. In addition they are usually temporary.  I do not recommend them.

6)    This level of protein intake is safe for almost everyone. The major exception would be people with kidney disease, who should always check with their doctor before increasing protein intake. The only other caveat is that protein metabolism creates a lot of nitrogenous waste, so you should drink plenty of water to flush that waste out of your system. But, water is always a good idea.

7)     The high protein diets minimized, but did not completely prevent, muscle loss. Other studies suggest that adding the amino acid leucine to a high protein diet can give 100% retention of muscle mass in a weight loss regimen – but that’s another story for another day.
