Coronavirus, the Cancel Culture and Tiny Betrayals of Purpose

In the last two decades, it has become more and more clear that the average American has trouble facing reality. The average American has trouble facing truth. It affects each of us, and it is affecting physicians, nurses and health professionals individually.

At least once a week, one of my patient’s refuses to get on the scale. Why would you visit the doctor to improve your health, and yet refuse to look at a measure of health? Yet, that is the accepted culture of today.

Language of Euphemism

Another evidence of this can be seen in the changes to our language. Our language has become flowered with euphemism and politically correct phrases. It is why we have a whole generation hyper-focused on “cancel culture.” People have set aside their faith to live by their feelings. People no longer accept another’s right to share their perspective or express themselves, especially if it hurts another’s feelings. We’ve created soft language that has taken the life out of life and medicine.

Shell Shock to PTSD

An example of this change is the softening of language describing what happens to a persons nervous system when in combat. During World War I from 1914 to 1918, if a soldier’s nervous system became overwhelmed due to the fatigue, stress and horror of battle it was called “shell shock.” The term describes the power and struggle that occurs with this overwhelming stress. The word almost echos the rattle of a cannon on one’s soul. Men would return home with hysteria, muscle contractions, heart palpitations, dizziness, depression, blindness, paralysis, insomnia, loss of appetite, flashbacks, nightmares or unable to speak without any physical damage to explain the symptoms. Because little was understood about the cause, it was seen as a sign of emotional weakness. Many were even branded as deserters or cowards because of the condition shell shock would cause. At the end of the war, 80,000 men were diagnosed with shell shock in the British Army medical facilities.

But instead of addressing the pain and addressing the trauma, we buried it under the jargon and euphemisms. After the second world war in 1945, we toned the term down because we didn’t want to hurt anyone’s feelings describing them as “shell shocked.” So, we called it “Battle Fatigue.” It is the same problem, overwhelming a person’s emotional coping mechanisms and nervous system with stress to the point of failure, but “battle fatigue” just sounded better, and softer.

Enter the Korean War of 1950-1951. Actually, we softened that too. It wasn’t really a war, we were told, and our leaders turned it from war into a softer more acceptable “Korean Conflict.” Men and women who encountered the same overpowering effects on the nervous system from witnessing the horror of battle, death and destruction were told they had “operational exhaustion.” This was an even softer term that allowed for a further avoidance of the truth.

Five years later, the U.S. entered a 19 year “conflict” with Vietnam. The politicians of the time didn’t want to call it war either. The same trauma causing shell shock in World War I was experienced by men and women in Vietnam. Seeing the horrors of battle on a daily basis and only being allowed to police those attacking you with guerrilla warfare in a foreign country led to severe trauma in many of our soldiers. Fighting was intense and millions of people were killed including 60,000 U.S. soldiers. Yet, we further softened the term “operational exhaustion” with the same symptoms of shell shock to “Post-traumatic Stress Syndrome (PTSD).” (Hey, at least they added a hyphen, right?)

Waking The Tiger – Working Through Trauma

Trauma is trauma, no matter how or where you experience it. Because of it’s complexities, the treatment of trauma can’t be addressed here, but according to Peter Levine in his book Waking the Tiger, trauma, no matter what the cause, must be worked through. Peter Levine does a wonderful job in explaining this in his second follow up book In An Unspoken Voice. There are additional treatments for burnout. The brain has a consistent pattern that it follows to resolve trauma and burnout. If that pattern is disrupted, shell shock, battle fatigue, operational exhaustion or PTSD ensues.

Elizabeth Metraux describes this in her 2018 article this way:
“I was on my honeymoon in Colombia when I first became aware of the true extent of my post-traumatic stress disorder. My husband and I were walking across a smooth, granite platform to take a closer look at a fountain in downtown Cartagena. As we neared the structure, mist from the fountain’s jets dampened the ground at my feet.

“I froze, paralyzed with fear by a flashback — my first — triggered by something as ordinary as wet pavement on a warm day.

“Two years earlier, I was working in civic engagement efforts in Baghdad. One morning, as I walked across a smooth, granite platform toward my apartment, gunfire erupted. I tried to run, but my flip-flops bested me on the pavement, still damp from an early mopping. I slipped and fell backward, hitting my head hard enough to knock me out. When I opened my eyes minutes later, the platform was covered with my blood.

“That happened 15 years ago this week, those Ides of March when American forces invaded Iraq.

“Back home in the U.S., it was clear to those around me that I had PTSD. It wasn’t until six months after my honeymoon, however, that I had the courage to acknowledge that I needed help. It’s not easy seeing your own weaknesses, much less conceding them. But when my habitual glass of wine with dinner became a bottle, and fireworks left me sore and sleepless for days, it was hard to fight the signs.

“Celexa for guilt. Ambien for sleep. Therapy for months. My psychologist and primary care physician spoke regularly to coordinate my care. Most importantly, family and friends became members of my care team. Isolation is a trauma victim’s ill-advised drug of choice, one my loved ones and clinicians wouldn’t let me take.”

Most Physicians Suffer from Moral Trauma combined with PTSD

What concerns me is that many of today’s heath-care workers, physicians and nurses, suffer from PTSD and moral trauma. Dr. Metraux goes on to describe a conversation she has that is reminiscent of many recent conversations I’ve had with my colleagues:

“A few weeks ago, I was talking with a physician who served our country in Iraq. We chatted nostalgically about the taste of sand and shawarma before he said something that gave me pause: ‘You know, I’d go back to the field any day. Beats practicing in my clinic.’
“‘Why’s that?’ I asked.
“’I didn’t become a doc to put up with billing codes and power struggles. I thought that PTSD would hit when I came home from Fallujah. It’s so much worse when I come home from the office. Truth is, I’ve lost my sense of purpose.’”

Physician burnout is easily chalked up to the 4-8 minute hurried visit with 30-40 patients per day, and the additional 6-8 hours spent each day entering patient information into an electronic medical record, combined with the life-and-death decisions this profession requires routinely every day. Add to it a time when a physicians and nurses are called upon to be the only people in the clinics and hospitals taking care of a viral infection still unknown in its full spectrum. But, that doesn’t even scratch the surface.

Thousands of Tiny Betrayals of Purpose

The real cause of injury is the fear created by a society that doesn’t really want to hear or face the truth, and the hundreds and thousands of tiny betrayals of purpose that occur every day in the clinic or the hospital. Most physicians find themselves expressing horror and disgust at how far they’ve been steered away from their primary purpose of taking care of people. Clinicians and nurses, much like combat veterans, are forced to take actions every day that contradict their core purpose – sometimes compulsory, sometimes voluntary. It causes a slow imperceptible unwinding of character.

The 4-8 minute visit means the physician can’t take time to build a real relationship with you or take care of the whole person whose real diagnosis can’t be logged into a computer. The 8 hours of daily charting requires the clinicians eyes to be taken off their patients, missing the humanity that brought us to the work in the first place. The government mandated “quality metrics” imposed on every patient encounter by Medicare, Medicaid and intrusive insurance plans that crowds out the deeper connection with patients to help them manage triggers, feel truly cared for and navigate treatments. Each of these are a “tiny betrayals of purpose,” 30-40 times a day over the course of weeks and months and years. When you subconsciously betray yourself with every interaction you have throughout the day, it adds up.

Medicine now requires clinicians to practice in a manner inconsistent with their values, because it saves costs, increases access and improves quality, . . . maybe. Then, add a new virus with an unknown morbidity, mortality and infectivity to the spectrum without a clear treatment protocol. Then add to that layers of bureaucratic regulation and mandates around treatment and insurance.

In 20 years of medical practice, including battlefield medicine, I’ve never seen physicians express public fear, angst and fatigue in the course of their duty. I’ve seen it every day in the last year.

We Lose a Physician Every Day

Since 2018, over 400 physicians committed suicide per year. Every day, at least one physician commits suicide (Tanwar D, Amer Psych Asso 2018 Annual Meeting). That is the highest rate of suicide in any profession. 40 suicides per 100,000 is twice that of the general population. This rate is higher than the military. The claim is that doctors are under-treated or untreated for their depression. It is more than that. Doctors and nurses alike are experiencing “shell shock,” or in today’s vernacular, “post-traumatic stress disorder” and being force to live, work and function all while suffering with subconscious moral injury. It goes untreated and unrecognized.

It’s why your doctor is curt with you. It’s why he or she can only spend five minutes with you in the exam room. It’s why you get the sense of fear from them when dealing with COVID-19. It’s why there is confusion about wearing masks and why so many physicians struggle to keep up with the ever changing science. It’s why 30% of them are divorced. It’s why 73% of the physicians and 50% of nurses you meet are effected by burnout, trauma and PTSD.

The challenge, is it’s only going to get worse before it gets better. Some will leave medicine, some will leave life. Others will suffer until it kills them. Unless, you and I change it. Until then, society will be offended.

Does Long Term Ketosis Cause Insulin Resistance?

We’ve never really seen a man or an elephant in long term ketosis before . . .

“It’s a snake.”

“It’s a wall.”

“It’s a rope.”

“It’s a fan.”

“It’s a tree.”

“It’s insulin resistance.”

I’ve always been fascinated by those describing a “new finding” in medicine. I am reminded of the story of 5 men who, never having seen an elephant before, were blindfolded and asked to describe what he discovered. However, each man was introduced to a different part of the elephant. Each of them had a dramatically different description of the elephant and each made a conclusion that was very different from the others.

What is fascinating, is that we usually make our “blindfolded comparisons” to those things we have seen or about which we have some descriptive understanding. Observing and describing human physiology is much like examining an elephant while blindfolded for the first time.

This week’s “blind-folded finding” is what has been interpreted by some as “insulin resistance” made worse by a ketogenic diet. Really? This perked my curiosity, because I’ve personally been following a low-carbohydrate/ketogenic diet for years and have thousands of patients doing the same. To this day, I’ve never seen insulin resistance “get worse.” In fact, it gets better. Clinically, it seems to take about 18-24 months to improve, but, it usually gets better.

THE QUESTION –

I’ve had three people from around the world contact me this week and ask why, after being on a ketogenic diet and “in ketosis,” they suddenly get a notably large blood glucose spike when they cheat. By notably large, I mean that their blood sugars rise to over 200 mg/dl within 2 hours of a carbohydrate containing meal. Now, they admit to rapid glucose recovery within an hour or two, and their hemoglobin A1c levels are subjectively normal (less than 5.6%). The worry is “am I becoming diabetic?” They also complain that after having been in ketosis for longer than 3-4 months, they cannot get their fasting blood sugars below 100 mg/dl.

Those asking me the question about this anomalous “physiological insulin resistance” referred to a couple of off-the-cuff blogger’s posts from 2-3 years ago referencing a few small studies (some of which were very poorly designed) [here, here, here & here] in the journals from 10-20 years ago. These articles describe a physiologic response interpreted as worsening “insulin resistance.” However, if you understand what is actually occurring in the Ketonian (yes, I made that term up – there will soon be a whole village of us), I see it as a normal physiologic response. It is misinterpreted by those who’ve never actually seen long term ketogenic physiology, as anomalous, in the average human.

THE ANSWER –

I’ve been seeing this slight elevation in fasting blood sugar with normal or low normal HbA1c in myself and many of my patients for quite some time. However, I never saw it as “insulin resistance” worsening. Clinically, when I tease out the food logs, it usually ends up being protein intake is too high, the person is using a sweetener or creamer causing rebound morning glucose elevation or, in those with low normal HbA1c’s (4.3-5.6%), it is in actuality a protective mechanism of “physiologic glucose sparing” in the keto-adapted individual (1, 2).

It can very easily be explained when one understands how ketones are actually used in the keto-adapted individual. First, a wonderful figure below (Thank you for pointing me to this one, Dr. Peter Attia) found in Dr. Veech et. al.’s paper (3) gives us an overview of how ketones skirt the TCA cycle within the mitochondria of the cell, causing inhibition of pyruvate dehydrogenase leading to glucose sparing by the cells of the brain that still require it’s availability (Oh, by the way, this is how we survived harsh winters and famines).

From the Figure 1 above, you can see that beta-hydroxybuterate [BHB (a ketone)] is converted to acetoacetyl CoA leading to the production of pyruvate, block-aiding additional glycolysis or inhibiting further glucose production at the liver level. Because the muscle tissues become more adept at using BHB, GLUT receptors are down-regulated at the muscle level as a person becomes more keto-adapted. Although we still have much to learn about the keto-adapted state, we know that this occurs more prominently in the muscle tissues than in the gut and brain. This fascinating glucose sparing phenomenon, has been interpreted by some as “worsening insulin resistance.”

Not to worry, glucose sparing is rapidly reversible and transitory within 1-3 days of increasing carbohydrate intake above 100-150 grams per day (1). It is also why those who become keto-adapted get a carbohydrate hangover including headache, stomach cramps, diarrhea, and malaise lasting 8-24 hours after cheating.

Is this bad? Absolutely not! It is NORMAL! (It’s just that most people, physicians included don’t know what the normal physiology of the Ketonian should look like.) Is it going to kill you, cause a stroke or give you a heart attack? Absolutely not. The elevated BHB actually increases production of adiponectin, leucine & glutathione that have antioxidant properties protecting one from transient inflammatory rises in blood sugar, enhancing insulin’s effect on the muscle, and preserving muscle mass while allowing for fat metabolism (4, 5, 6).

THE TAKE-HOME MESSAGE –

First, don’t cheat if you don’t want to see transient rises in blood sugar and experience the wonders of a carbohydrate hangover and some mild reactive hypoglycemia (low blood sugar) after the fact.

Second, if you’ve been in ketosis for longer than 3-4 months, and you absolutely must get another two or three hour oral glucose tolerance test (OGTT), you might want to increase your carbohydrate intake to 50-100 grams per day 1-3 days before the test to avoid an anomalous spike in blood glucose. (One OGTT was enough for me . . . but hey, some of us are gluttons for punishment.)

Third, enjoy your eggs, pass the bacon and stir me up some Keto//OS.

Why the Calorie is NOT King

Today in the office I had the calorie conversation again . . . three times. We have an entire society with a very influential health and fitness industry built around the almighty calorie. Has it helped? Looking at our 5 year obesity outcomes. It hasn’t helped a bit. In fact, it is worse. In 1985 only 19% of U.S. adults were obese.

U.S. Obesity Adult 2011

U.S. Adult Obesity 2014

In 2014, 34.5% of U.S. adults were obese. The numbers this year are approaching 35.6% You can see the dramatic increase in obesity by 1-3% every year for the last 5 years in the CDC images above.

For over 50 years we have been told that caloric restriction and fat restriction is the solution. But by the numbers above, the 58 million people in the U.S. utilize a gym or health club to burn off those calories aren’t seeing the success that they should be expecting.

Why? Because the calorie is NOT king. What do I mean by that? We don’t gain weight because of the thermogenic dogma we’ve been taught for the last 50 years. Our weight gain is driven by a hormone response to food. Hear more about why the calorie is NOT king on tonight’s PeriScope. You can Katch it here with all the live stream comments and hearts at Katch.me/docmuscles.

Caffeine . . . Weight Loss Wonder Boy or Sneaky Scoundrel?

I’ve been looking for the answer for quite some time. . . what role does caffeine play in your and my weight management journey? The answer gave me a headache. . . literally and figuratively.

As many of you, including my office staff, know, I love my Diet Dr. Pepper (and my bacon). I found that being able to sip on a little soda throughout the day significantly helped the carbohydrate cravings and munchies during a busy and stressful day at the office. Diet Dr. Pepper contains caffeine, however, I wasn’t really worried. Caffeine has been well know to have a thermogenic effect which increases your metabolism and has been thought for many years to help with weight loss among the weight loss community.

Diet Dr. Pepper is, also, one of only four diet sodas on the grocery store shelves that doesn’t contain acesulfame potassium (click here to see why most artificial sweeteners cause weight gain). The four diet sodas that I have been comfortable with my patients using are Diet Dr. Pepper, Diet Coke, Diet Mug Root-beer and Diet A&W Cream Soda. These are the last four hold out diet sodas that still use NutraSweet (aspartame) as the sweetener. Most of the soda companies have switched the sweetener in their diet sodas to the insulinogenic acesulfame potassium because it tastes more natural and aspartame has been given a media black eye of late. However, NutraSweet (aspartame) is the only sweetener that doesn’t spike your insulin or raise blood sugar (click here to find out why that is important).

Yes, I know. The ingestion of 600 times the approved amount of aspartame causes blindness in lab rats (but we’re not lab rats, and . . . have you ever met someone that drinks 600 Diet Dr. Peppers in a day? The lethal dose of bananas, which are high in potassium that will stop your heart, is 400). Aspartame can also exacerbate headaches in some (about 5% of people) and I’ve had a few patients with amplified fibromyalgia symptoms when they use aspartame. But for most of us, its a useful sweetener that doesn’t spike your insulin response, halting or causing weight gain.

But, over the last few years, I’ve noticed that increased amounts of Diet Dr. Pepper & Diet Coke seem to cause plateauing of weight and decreasing the ability to shift into ketosis, especially mine. I’ve also noticed (in my personal n=1 experimentation) that my ability to fast after using caffeine regularly seems to be less tolerable, causing headaches and fatigue 8-10 hours into the fast, symptoms that don’t seem to let up until eating. Through the process of elimination, caffeine seems to be the culprit.

After mulling through the last 10 years of caffeine research, most of which were small studies, had mixed results, used coffee as the caffeine delivery system (coffee has over 50 trace minerals that has the potential to skew the results based on the brand) and never seemed to ask the right questions, the ink from a study in the August 2004 Diabetes Care Journal screamed for my attention.

It appears that caffeine actually stimulates a glucose and insulin response through a secondary mechanism. The insulin surge and glucose response is dramatically amplified in patients who are insulin resistant. Caffeine doesn’t effect glucose or insulin if taken while fasting; however, when taken with a meal, glucose responses are 21% higher than normal, and insulin responses are 48% higher in the insulin resistant patient. Caffeine seems to only effect the postprandial (2 hours after a meal) glucose and insulin levels. The literature shows mixed responses in patients when caffeine is in coffee or tea, probably due to the effect of other organic compounds (1).

Caffeine effect on plasma glucose and plasma insulin compared to placebo (1).

Caffeine also diminishes insulin sensitivity and impairs glucose tolerance in normal and already insulin resistant and/or obese patients. This is seen most prominently in patients with diabetes mellitus type II (stage IV insulin resistance). Caffeine causes alterations in glucose homeostasis by decreasing glucose uptake into skeletal muscle, thereby causing elevations in blood glucose concentration and causing an insulin release (2-6).

Studies show that caffeine causes a five fold increase in epinephrine and a smaller, but significant, norepinephrine release. The diminished insulin sensitivity and exaggerated insulin response appears to be mediated by a catacholamine (epinephrine, norepinephrine & dopamine) induced stress response (5). Caffeine has a half life of about 6 hours, that means the caffeine in your system could cause a catacholamine response for up to 72 hours depending upon the amount of caffeine you ingest (7).

The reason for my, and other patient’s, headaches and fatigue after a short fast was due to the exaggerated stress hormone response. Increased levels of insulin were induced by a catacholamine cascade after caffeine ingestion with a meal, dramatically more amplified in a person like me with insulin resistance. The caffeine with the last meal cause hypoglycemia 5-7 hours into the fasting, leading to headaches and fatigue that are only alleviated by eating.

Even when not fasting, the caffeine induced catacholamine cascade causes up to 48% more insulin release with a meal, halting weight loss and in some cases, causing weight gain.

Caffeine is not the “Wonder-Boy” we thought it was.

How much caffeine will cause these symptoms? 50 mg or more per day can have these effects.

Ingestion of caffeine has the following effects:

20-40 mg – increased mental clarity for 2-6 hours
50-100 mg – decreased mental clarity, confusion, catacholamine response
250-700 mg – anxiety, nervousness, hypertension & insomnia
500 mg – relaxation of internal anal sphincter tone (yes . . . you begin to soil yourself)
1000 mg – tachycardia, heart palpitations, insomnia, tinnitus, cognitive difficulty.
10,000 mg (10 grams) – lethal dose (Yes, 25 cups of Starbucks Coffee can kill you)

The equivalent of 100 mg of in a human was given to a spider, you can see the very interesting effect on productivity. How often does the productivity of the day feel like the image below?

Normal Spider (9)

Spider on caffeine (9)

Beware that caffeine is now being added to a number of skin care products including wrinkle creams and makeup. Yes, caffeine is absorbed through the skin, so check the ingredients on your skin care products.

Diet Dr. Pepper, my caffeine delivery system of choice, has slightly less caffeine (39 mg per 12 oz can or 3.25 mg per oz) than regular Dr. Pepper. I found myself drinking 2-3 liters of Diet Dr. Pepper per day (long 16-18 hour work days in the office). After doing my research, I realized that my caffeine tolerance had built up to quite a significant level (230-350 grams per day).

So, a few weeks ago, I quit . . . cold turkey.

Did I mention the 15 withdrawal symptoms of caffeine? (8)

Headache – behind the eyes to the back of the head
Sleepiness – can’t keep your eyes open kind of sleepiness
Irritability – everyone around you thinks you’ve become a bear
Lethargy – feels like your wearing a 70 lb lead vest
Constipation – do I really need to explain this one?
Depression – you may actually feel like giving up on life
Muscle Pain, Stiffness, Cramping – feel like you were run over by a train
Lack of Concentration – don’t plan on studying, doing your taxes or performing brain surgery during this period
Flu Like Illness – sinus pressure and stuffiness that just won’t clear
Insomnia – you feel sleepy, but you can’t sleep
Nausea & Vomiting – You may loose your appetite
Anxiety – amplified panic attacks or feeling like the sky is falling
Brain Fog – can’t hold coherent thoughts or difficulty with common tasks
Dizziness – your sense of equilibrium may be off
Low Blood Pressure & Heart Palpitations – low pressure and abnormal heart rhythm

I experienced 13 of the 15 that lasted for 4 days. I do not recommend quitting cold turkey unless you have a week off and someone to hold your hand, cook your meals and dose your Tylenol or Motrin. My wife thought I was dying. . . I thought I was dying on day two. I actually had a nightmare about buying and getting into my own coffin. It can take up to three weeks to completely recover from caffeine withdrawal.

The other way to quit is to decrease your caffeine intake by 50 mg every two days. That means decrease caffeine by:

1 can of soda every two days
1/4 cup of coffee every day
1/2 can of Energy Drinks every two days
1 cup of tea every two days

The benefit of this method is that withdrawal symptoms are much less severe without the caffeine headache and the ability to remain productive. It will take longer, but quitting cold turkey is not a pretty picture. Been there . . . done that, . . . and I’m not going back. I actually lost another half inch off my waistline by day 5 of caffeine discontinuation.

What is the take home message here? If you have any degree of insulin resistance, caffeine makes it worse and will amplify your weight gain as well as decrease the productivity of your day.

Adrenal Insufficiency, Adrenal Fatigue, PseudoCushing’s Syndrome – Oh My!

Adrenal Fatigue? Adrenal Insufficiency? Cortisol? PseudoCushing’s Syndrome? What do these terms mean and why are they all over the internet these days? And, what do they have to do with your weight loss?

This was our topic this evening on PeriScope. Katch Dr. Nally speak about this topic with rolling comments at Katch.me/docmuscles. Or you can watch the video below:

If you’re not sure about what this is, you’re not alone. I think I’ve heard the term “Adrenal Fatigue” at lease four times a day for the last three months. If you ask your doctor, they’ll probably scratch their heads too. The funny thing is that “Adrenal Fatigue” isn’t a real diagnosis, but it is all over the internet and it shows up in the titles of magazines in the grocery store every day. There’s even and “Adrenal Fatigue For Dummies” so it must be real, right?!

No. It isn’t a real diagnosis. It is a conglomeration of symptoms including fatigue, difficulty getting out of bed in the morning, and “brain fog” that have been lumped together to sell an “adrenal supplement.” (Sorry, but that’s really what it is all about.) Do a Google search and the first five or six sites describing adrenal fatigue claim the solution is taking their “special adrenal supplement.”

I know what you’re thinking, “Your just a main stream, Western Medicine doctor, Dr. Nally, you wouldn’t understand.” Actually, I do understand.

Adrenal fatigue has risen in popularity as a “lay diagnosis” because many patients show up at their doctors office with significant symptoms that actually interfere with their ability to function, and after all the testing comes back negative for any significant illness, they are told that they are normal. But the patient still has the symptoms and no answer or treatment has been offered. It’s discouraging. . . very discouraging.

That’s because the symptoms are actually the body’s response to chronic long term stress. Many of my patients, myself included, have found themselves “stuck” in their weight loss progression, feeling fatigued, struggling to face the day, with a number of symptoms including cold intolerance, memory decline, difficulty concentrating, depression, anxiety, dry skin, hair loss, and even infertility in some cases. Is it poor functioning adrenal glands? No, your feeling this way because the adrenal glands are actually doing their job!!

If the adrenal glands weren’t working you’d experience darkening of the skin, weight loss, gastric distress, significant weakness, anorexia, low blood pressure, and low blood sugar. The symptoms are actually called Addison’s disease and it is actually fairly rare (1 in 100,000 chance to be exact). So what is causing the symptoms you ask?

There are a number of reasons, but one that I am seeing more and more frequently is “Pseudo-Cushings’s Syndrome.” Pseudo-Cushing’s Syndrome is a physiologic hypercortisolism (over production of cortisol) that can be caused by five common issues:

Chronic Physical Stress
Severe Bacterial or Fungal Infections that Go Untreated
Malnutrition or Intense Chronic Exercise
Psychological Stress – including untreated or under-treated depression, anxiety, post-traumatic stress, or dysthymia (chronic melancholy)
Alcoholism

The psychiatric literature suggest that up to 80% of people with depressive disorders have increased cortisol secretion (1,2,3). People with significant stressors in their life have been show to have an increased corsiol secretion. Chronic stress induces hyperactivity of the hypothalamic-pituitary-adrenal axis causing a daily, cyclic over production of cortisol and then normalization of cortisol after resolution of the stressor. This cortisol response is not high enough to lead to a true Cushing’s Syndrome, but has the effect of the symptoms listed above and begins with limiting ones ability to loose weight.

I’m convinced that this is becoming more and more prevalent due to the high paced, high-stress, always on, plugged in, 24 hour information overload lives we live.

What is cortisol? It is a steroid hormone made naturally in the body by the adrenal cortex (outer portion of the adrenal gland). Cortisol is normally stimulated by a number of daily activities including fasting, awakening from sleep, exercise, and normal stresses upon the body. Cortisol release into the blood stream is highest in the morning, helping to wake us up, and tapers into the afternoon. Cortisol plays a very important role in helping our bodies to regulate the correct type (carbohydrate, fat, or protein) and amount of fuel to meet the bodies physiologic demands that are placed upon it at a given time (4,5,6).

Under a stress response, cortisol turns on gluconeogensis in the liver (the conversion of amino acids or proteins into glucose) for fuel. Cortisol, also, shifts the storage of fats into the deeper abdominal tissues (by stimulating insulin production) and turns on the maturation process of adipocytes (it makes your fat cells age – nothing like having old fat cells, right?!) In the process, cortisol suppresses the immune system through an inhibitory effect designed to decrease inflammation during times of stress (7,8,9). If this was only occurring once in a while, this cascade of hormones acts as an important process. However, when cortisol production is chronically turned up, it leads to abnormal deposition of fat (weight gain), increased risk of infection, impotence, abnormal blood sugars, brain fog, head
aches, hypertension, depression, anxiety, hair loss, dry skin and ankle edema, to name a few.

The chronic elevation in cortisol directly stimulates increased insulin formation by increasing the production of glucose in the body, and cortisol actually blunts or block-aids the thyroid function axis. Both of these actions halt the ability to loose weight, and drive weight gain.
Cortisol also increases appetite (10). That’s why many people get significant food cravings when they are under stress (“stress eaters”). Cortisol also indirectly affects the other neuro-hormones of the brain including CRH (corticotrophin releasing hormone), leptin, and neuropeptide Y (NPY). High levels of NPY and CRH and reduced levels of leptin have also been shown to stimulate appetite and cause weight gain (10-11).

How do you test for Pseudo-Cushing’s Syndrome?

Testing can be done by your doctor with a simple morning blood test for cortisol. If your cortisol is found to be elevated, it needs to be repeated with an additional 24 hour urine cortisol measurement to confirm the diagnosis. If Cushing’s Syndrome is suspected, some additional blood testing and diagnostic imaging will be necessary. Pseudo-Cushing syndrome will demonstrate a slightly elevated morning cortisol that doesn’t meet the criteria for true Cushing’s type syndrome or disease.

How do you treat it?

First, the stressor must be identified and removed. Are you getting enough sleep? Is there an underlying infection? Is there untreated anxiety or depression present? Are you over-exercising? These things must be addressed.

Second, underlying depression or anxiety can be treated with counseling, a variety of weight neutral anti-depressant medications or a combination of both. Many of my patients find that meditation, prayer, and journaling are tremendous helps to overcoming much of the anxiety and depression they experience.

Third, adequate sleep is essential. Remove the television, computer, cell phone, iPad or other electronic distraction from the bedroom. Go to bed at the same time and get up at the same time each day. Give yourself time each day away from being plugged in, logged in or on-line.

Fourth, mild intensity (40% of your maximal exertion level) exercise 2-3 days a week was found to lower cortisol; however, moderate intensity (60% of your maximal exertion level) to high intensity (80% of your maximal exertion level) exercise was found to raise it (12). A simple 20 minute walk, 2-3 times per week is very effective. Find a hobby that you enjoy and participate in it once or twice a week. Preferably, a hobby that requires some physical activity. The activity will actually help the sleep wake cycles to improve.

Fifth, follow a low carbohydrate or ketogenic diet. Ketogenic diets decrease insulin and reverse the effect of long term cortisol production. Ketogenic diets a have also been shown to decrease or mitigate inflammation by reducing hyperinsulinemia commonly present in these patients (13).

So, the take home message is . . . take your adrenal glands off of overdrive.

Diabetes Mellitus – Really the Fourth Stage of Insulin Resistance

I just completed my reading of Dr. Joseph Kraft’s Diabetes Epidemic & You. This text originally printed in 2008 and was re-published in 2011. I am not really sure why I have never seen this book until now, but I could not put it down. I know, I am a real life medical geek. But seriously, you should only read this book if you are concerned about your health in the future. Otherwise, don’t read it.

For the first time in 15 years, someone has published and validated what I have been seeing clinically in my office throughout my career. Dr. Kraft is a pathologist that began measuring both glucose and insulin levels through a three hour glucose tolerance blood test at the University of Illinois, St. Joseph Hospital in Chicago. This test consists of checking blood sugar and insulin in a fasted state, and then drinking a 100 gram glucose load followed by checking blood sugar and insulin at the 30, 60, 120 and 180 minute marks (a total of three hours).

Dr. Kraft completed and recorded this test over a period of almost 30 years on 14,384 patients between 1972 and 1998. His findings are landmark and both confirm and clarify the results that I have seen and suspected for years.

I am convinced that our problem with treating obesity, diabetes and the diseases of civilization has been that we defined diabetes as a “disease” based on a lab value and a threshold instead of identifying the underlying disease process. We have been treating the symptoms of the late stage of a disease that started 15 to 20 years before it is ever actually diagnosed. Diabetes is defined as two fasting BS >126, any random blood sugar >200, or a HbA1c >6.5%. (Interestingly this “disease” has been a moving target. When I graduated from medical school it was two fasting blood sugars >140 and the test called hemoglobin A1c (HbA1c) that we use today for diagnosis didn’t even exist). The semantics associated with this problem is that many of us recognize that the disease is not actually diabetes. The disease is (as far as we understand it today) insulin resistance or hyperinsulinemia. This is where Dr. Kraft’s data is so useful. Diabetes, as it is defined above, is really the fourth stage of insulin resistance progression over a 15-20 year period and Dr. Kraft’s data presents enormous and very clear evidence to that effect.

When I first entered private practice 15 years ago, I noticed a correlation and a very scary trend that patients would present with symptoms including elevated triglycerides, elevated fasting blood sugar, neuropathy, microalbuminuria, gout, kidney stones, polycystic ovarian disease, coronary artery disease and hypertension that were frequently associated with diabetes 5-15 years before I ever made the diagnosis of diabetes mellitus. I began doing 2 hour glucose tolerance tests with insulin levels and was shocked to find that 80-85% of those people were actually diabetic or very near diabetic in their numbers. The problem with a 2 hour glucose tolerance test, is that if you are diabetic or pre-diabetic, you feel miserable due to the very profound insulin spike that occurs. A few patients actually got quite upset with me for ordering the test, both because of how they felt after the test, and the fact that I was the only physician in town ordering it. So, in an attempt to find an easier way, I found that the use of fasting insulin > 5 nU/dl, triglycerides > 100 mg/dl and small dense LDL particle number > 500 correlated quite closely clinically with those patients that had positive glucose tolerance tests in my office. There is absolutely no data in the literature about the use of this triangulation, but I found it to be consistent clinically.

I was ecstatic to see that Dr. Kraft plowed through 30 years and over 14,000 patients with an unpleasant glucose tolerance test and provided the data that many of us have had to clinically triangulate. (I’m a conservative straight white male, but if Dr. Kraft would have been sitting next to me when I finished the book this afternoon, I was so excited that I probably would have kissed him.)

Insulin resistance or hyperinsulinemia (the over production of insulin between 2-10 times the normal amount after eating carbohydrates) is defined as a “syndrome” not a disease. What Dr. Kraft points out so clearly is that huge spikes in insulin occur at 1-2 hours after ingestion of carbohydrates 15-20 years prior to blood sugar levels falling into the “diabetic range.” He also demonstrates, consistently, the pattern that occurs in the normal non-insulin resistant patient and in each stage of insulin resistance progression.

The information extrapolated from Dr. Kraft’s research give the following stages:

Stages of insulin resistance by 3 hr OGTT extrapolated from “Diabetes Epidemic & You”

From the table above, you can see that the current definition of diabetes is actually the fourth and most prolifically damaging stage of diabetes. From the data gathered in Dr. Kraft’s population, it is apparent that hyperinsulinemia (insulin resistance) is really the underlying disease and that diabetes mellitus type II should be based upon an insulin assay instead of an arbitrary blood sugar number. This would allow us to catch and treat diabetes 10-15 years prior to it’s becoming a problem. In looking at the percentages of these 14,384 patient, Dr. Kraft’s data also implies that 50-85% of people in the US are hyperinsuliemic, or have diabetes mellitus “in-situ” (1). This means that up to 85% of the population in the U.S. is in the early stages of diabetes and is the reason 2050 projections state that 1 in 3 Americans will be diabetic by 2050 (2).

Insulin resistance is a genetically inherited syndrome, and as demonstrated by the data above has a pattern to its progression. It is my professional opinion that this “syndrome” was, and actually is, the protective genetic mechanism that protected groups of people and kept them alive during famine or harsh winter when no other method of food preservation was available. It is most likely what kept the Pima Indians of Arizona, and other similar groups, alive while living for hundreds of years in the arid desert. This syndrome didn’t become an issue among these populations until we introduced them to Bisquick and Beer.

The very fascinating and notably exciting aspect of this whole issue is that insulin resistance is made worse by diet and it is completely treatable with diet. This is where the low carbohydrate diet, and even more effective ketogenic diet or lifestyle becomes the powerful tool available. Simple carbohydrate restriction reverses the insulin spiking and response. In fact, I witness clinical improvement in the insulin resistance in patients in my office over 18-24 months every day. You can get a copy of my Ketogenic Diet here in addition to video based low carbohydrate dietary instruction.

Until we are all on the same page and acknowledge that diabetes is really the fourth stage of progression on the insulin resistance slippery slope, confusion and arguments about treatment approaches will continue to be ineffective in reducing the diseases of civilization.
