Estrogen Dominance – The Dead Man’s Curve on the Road to Ketogenic Happiness

Over the last 18 years of my practice, I’ve seen tremendous success in helping people improve their health when low-carbohydrate dietary changes are anchored as the foundation of treatment.  However, there is still a group of people that struggle with seeing success.  Even with the most effective ketogenic dietary control, there are those that see abnormal weight gain, inability to lose weight, poor libido, fatigue, foggy thinking, mood swings, persisting depression, headaches, bloating, breast tenderness, fibro-cystic breast changes, hair loss, and hot flashes.  They may not experience all these symptoms, however, many are often present.  If you have been following a ketogenic lifestyle and are still experiencing any of these symptoms, you are probably suffering from estrogen dominance.

Estrogen dominance is a condition that elusively effects thousands of women (and men) and your doctor probably doesn’t even know about it.  I didn’t know about it.  I, like all of my physician colleagues, were trained in school that the symptoms above are related to fluctuations of estrogen as a woman ages (or dropping of testosterone as a man ages).  We were, and still are, taught that they are fixed by giving more powerful doses of estrogen or testosterone.

Over the years of my clinical experience, giving more estrogen frequently didn’t work.  And, giving men more testosterone didn’t work either.  What I found very effective, for many, was changing the diet.  And, for about 85% of people, the symptoms list above resolved.  However, the cause of the symptoms above in that last 15% of patients I see was still elusive.  Examinations, blood tests, and even psychological evaluations never revealed the answer.  Giving synthetic estrogen, progestin or testosterone when the blood work showed abnormality partially alleviated some of the symptoms for a few months, but then the patients would end up back in my office with the symptoms having returned.

I’ve found a number of problems following the “standard” medical approach to using synthetic sex hormones.

The first problem is that estrogen, progesterone and testosterone are heavily bound to proteins in the blood. It is only the free component of the three forms of estrogen and progesterone in the body and the free testosterone that acts upon the delicate cells located throughout the body.  Blood testing does not account for the levels of free estrogen forms and progesterone effectively.  These can only be tested through salivary testing.

The second obstacle is that the synthetic forms of progesterone (progestin), cannot effectively enter the brain. When synthetic forms are used, a person only gets half the benefits of progesterone found in the human body.  This is why so many women have depression, anxiety and foggy brain feelings when using the synthetic versions.

The third challenge is that pharmaceutical companies cannot patent a drug that is identical to your human hormones.  The chemical structure of the synthetic estrogen, progestin or testosterone must be slightly different. Hormones effectively work on certain aspects of various cells throughout the body, however, progesterone and progestin (the synthetic version found in medroxyProgesterone) DO NOT have the same hormonal effect on each cell.  Natural progesterone is broken down by the stomach when ingested. That’s why progestin was invented, however, it doesn’t act the same in the body and only does half the job.

The fourth dilema is that much of our food in the standard American Diet stimulates increased estrogen production or inhibits clearance of estrogen excess through the gut and digestive tract.  This happens in men and women.  We can get excess estrogen from animals treated with hormones in meats, milk and dairy products.  Hydrogenated oils in processed foods change the way estrogen and progesterone are handled in the body.  These unstable fats increase the effects of estrogen on the body and amplify the risk for cancers.  Excessive omega-6 fatty acids in the diet magnify estrogen receptor response to estrogen.

Estrogen metabolism in the liver and removal in the gut are dependent on vitamins B & E, magnesium  and idol-3-carbinol (IC3).  Diets without adequate IC3 from glucobrassicin found in leafy green and crucirferous vegetables allow re-uptake of estrogen in the gut leading to high estrogen levels and estrogen dominance.  This is where gut health is even more important, and where I see failure in the “carnivore” approach to a ketogenic lifestyle.

The fifth problem is that the more estrogen I give a person, the more estrogen receptors are unregulated to the surfaces of the cells in the body.  When that happens, more estrogen is required.  Excess estrogen can actually cause many of the same symptoms present in progesterone deficiency including:

  • Irregular or heavy bleeding
  • Breast tenderness
  • Depression
  • Fatigue
  • Poor concentration
  • Fibrocystic breast changes
  • Decreased libido
  • Fibroid growth on the uterus
  • Endometriosis
  • Water retention and bloating
  • Fat gain around hips and thighs
  • Bone mineral loss (osteoporosis)
  • Hair loss
  • Skin thinning
  • Disturbed sleep
  • Breast and uterine cancer

More estrogen isn’t needed. Balancing natural progesterone with the current estrogen the body is already making is the solution in most cases.  This can only be effectively assessed through a salivary hormone test.

In my clinical experience, a ketogenic lifestyle is foundational to balancing these hormones consistently and naturally.  Carbohydrate restriction by itself corrects many of the diseases of civilization.  I addressed this in my book The Keto Cure.  For many, there are few more steps necessary to living a long, happy and healthy life.

The treatment to this issue isn’t difficult.  For that reason, much more is to come on this subject.  I will address each of the points above in future blogs. However, the first step is get your hormones checked by someone who understand this problem.  And, then knows how to interpret it and treat it.

The ketogenic diet isn’t just a great tool for helping people lose weight and feel their best; it’s also an extremely effective method for treating the common “diseases of civilization.”  The Keto Cure will give readers the prescription they need to heal their bodies by eating plenty of fat and moderating protein and carbs.

I’ve been advocating a low-carb, high-fat diet in my clinical practice for over fifteen years, helping people address their health problems by making better food choices. I teamed up with bestselling low-carb author and podcaster Jimmy Moore  to create a top-50 health podcast espousing the benefits of eating keto.  Now, for the first time, I’ve taken my years of clinical experience, put everything down on paper, and create a how-to guide that details all the ways in which the ketogenic diet can help remedy common ailments.

The Keto Cure details the science behind the keto diet’s effectiveness at treating a wide range of diseases, including:

  • Alzheimer’s
  • Epilepsy
  • Fatty liver disease
  • Hypercholesterolemia
  • Hypertension
  • Parkinson’s disease
  • Thyroiditis
  • Type 2 diabetes
  • and many more

The Keto Cure also outlines practical tips gleaned from Dr. Nally’s fifteen-plus years in medical practice, as well as Moore’s ten-plus years as a health and wellness podcaster, on overcoming the common pitfalls that people experience when adapting to a high-fat way of eating, including fatigue and keto flu. This helpful information, combined with a wide variety of delicious keto recipes from international bestselling cookbook author Maria Emmerich, makes The Keto Cure a complete resource for healing oneself with the ketogenic diet.

KetoDynamic Successes . . .

Adam Tiffini 

As I reviewed my website recently, I realized that I have posted lots of science but I’ve never posted any success stories.  So, as patient’s are comfortable & willing to share, I will begin posting these experiences here on the blogosphere for the world to witness their successes and the power of the KetoDynamic Antidote.  

The first success story is my own.  This picture of me and my wife, were taken after I had been following a ketogenic lifestyle for about 4 years.  I dropped 60 lbs, normalized my cholesterol and blood sugar also normalized.  I couldn’t and wouldn’t recommend these lifestyle changes unless I was willing to follow them for the long haul myself. I call people following a ketogenic lifestyle for longer than a year “Ketonians.”

Not only mine, but hundreds of patient’s having similar successes have become the greatest reward to my career as a physician over the last 15 years.  They are truly the “KetoDynamic Moments” that etch themselves into my memory and have made me such an advocate of a ketogenic lifestyle.  Therefore, it is with great honor and excitement that I have been allowed to share Michelle’s story below. 

  
Michelle started seeing me in October 2015. She has struggled with weight all her life and, now in her late 40’s, weighed 201 lbs with a waist circumference of almost 36 inches and a body mass index of 32.  Her “before” picture was taken just before a Halloween activity in 2015.  Her “after” picture was taken in late March 2016.  

A simple ketogenic lifestyle change ( <20g of carbohydrates, moderate protein for her ideal body weight & increasing fat to > 60% of total calories) has produced almost 50 lbs of weight loss and 6 inches off her waist in just 5 months.  This was with dietary change only (Michelle doesn’t exercise) and she’s still losing weight.  What is dramatic, and I see it every day, is that Michelle looks younger by at least 10 years (she actually added 20 years to her life span with this weight loss already).  She feels fantastic.  Blood sugar and cholesterol are now under control and she has tremendous amounts of energy.  Her picture in March is at a body mass index of 29.
Michelle doesn’t calorie restrict. She just eats until she is full.  Congratulations, Michelle!!! And, keep up the great work.

If you’d like to share your KetoDynamic successes with me and my audience, please let me know.

Thinking Outside of the Box

Nine dots

The image above has nine dots within a square.  Your task, using only four lines is to connect ALL nine dots WITHOUT ever raising your pen, pencil or finger (Please don’t use a sharpie on your computer screen . . . it doesn’t come off).

You may have seen this puzzle previously . . . it’s made its rounds in corporate training circles. But the underlying principle remains true.  The solution requires you to expand your thinking or to “think outside the box.”out-of-the-box

Whenever you find yourself on the side of the majority, it is time to pause and reflect. (Mark Twain)

Why should we limit ourselves to thinking outside the box.  Can’t we just get rid of the box?

True discovery consists in seeing what everyone has seen . . . then, thinking what no one has thought.

The answer can be found when those four lines are used beyond the box our mind creates:

Nine dots solution

What good has the box done us?  People were burned at the stake because they refused to believe the Earth was not the center of the universe. People were beheaded because they had a sneaking suspicion that the world was not flat.

Why is it so very hard to accept that our weight gain and diabetes are driven by a hormonal signal, and not by gluttony or caloric intake of fat?  The definition of insanity is doing the same thing repetitively and expecting a different outcome.  How long have you been restricting calories and fat with only minimal or no improvement in your weight, blood sugar, cholesterol or general feeling of health?diabetes global warming

The main problem with the current thought model, or dogma, on the obesity’s cause is that it does not account for metabolic syndrome.  Metabolic syndrome is insulin resistance.  It is an over production of insulin in the presence of ANY form of carbohydrate (sugar or starch).

In the practice of medicine over the last 15 years, I noticed that a very interesting pattern emerged.  There was always a spike in fasting and postprandial insulin levels 5-10 years prior to the first abnormal fasting and postprandial blood sugars.  These patients were exercising regularly and eating a diet low in fat.  But they saw continued weight gain and progressed down the path of metabolic syndrome.  10-15 years later, they fall into the classification of type II diabetes.  What I now lovingly refer to as stage IV insulin resistance.

The only thing that seems to halt this progressive process with any degree of success is carbohydrate restriction.  Fasting insulin levels return to normal, weight falls off, and the diseases of civilizations seem to disappear as insidiously as they arose.

So you tell me, is the world flat?  Is the Earth the center of the universe?

Common Ketosis Killers

“I’ve tried your low-carb diet, Dr. Nally, and it didn’t work.”

“Hmm . . . really?”  If you’re mumbling this to yourself, or you’ve said it to me in my office, then lets have a little talk.  You’ve probably been subjected to the common ketosis killers.

Scale HelpI’ve heard this statement before.  It’s not a new statement, but it’s a statement that tells me we need to address a number of items.  If you’ve failed a low carbohydrate diet, I’d suspect you are pretty severely insulin resistant or hyperinsulinemic.  You probably never really reached true ketosis.   I’d want to have you checked out by your doctor to rule out underlying disease like hypothyroidism, diabetes, other hormone imbalance, etc.

Nutritional Ketosis is Most Effective as a Lifestyle Change

Next, switching to a low-carbohydrate lifestyle is literally a “lifestyle change.”  It requires that you understand a few basic ketosis principles.  And, it takes the average person 3-6 months to really wrap their head around what this lifestyle means . . .  and, some people, up to a year before they are really comfortable with how to eat and function in any situation.

I assume, if you are reading this article, that you’ve already read about ketosis and understand the science behind it.  If not, please start your reading with my article The Principle Based Ketogenic Lifestyle – Part I and Ketogenic Principles – Part II.  If this is the case, then please proceed forward, “full steam ahead!”

There are usually a few areas that are inadvertently inhibiting your body transformation, so let’s get a little personal.

Nutritional Ketosis is a Very Low Carbohydrate Diet

First, this is a low carbohydrate diet.  For weight loss, I usually ask people to lower their carbohydrate intake to less than 2o grams per day. How do you do that?  (A copy of my diet is accessible through my membership site HERE.)  You’ve got to begin by restricting all carbohydrates to less than 20 grams per day.  Any more than 20 to 30 grams per day will cause an insulin release from the pancreas and stimulate fat storage of both carbohydrate and fat for the next 10-12 hours, commonly killing ketosis.  Keep a dietary journal to record your progress, your cravings, your successes and failures.  I’m going to want to see it and review it with you if you see me.

No, I don’t believe in “Net Carbs.”  Net Carbs are a sales gimmick to get you to buy “artificial food” that keeps you coming back for “artificial food” and halts your weight loss (you’ll see why shortly).   You’re going to lose the most weight and feel your best when you eat real food. I do allow for the subtraction of real fiber, specifically non-cooked, non-blended, non-juiced leafy greens (If you cook, blend or juice a leafy green, it activates more carbohydrate availability).  Leafy greens are real fiber.  You can subtract them.  In fact, I recommend eating 1-3 cups of leafy greens per day to help bowel function & provide necessary folic acid, but, everything else is “carbage.”  Avoid it.

Yes, cottage cheese and yogurt contain carbohydrates.  Be very cautious with them.

No, oatmeal and Cream of Wheat™ are not helpful. See my article on Why Your Oatmeal is Killing Your Libedo.Alcohol

Alcohol also halts your weight loss.  It’s not the sugar in the alcohol I’m worried about, the distilling process changes the sugar to alcohol, however, alcohol stimulates an insulin response after the alcohol is metabolized in the liver with a SIMILAR RESPONSE to regular sugar.

 

To Effectively Maintain Nutritional Ketosis, You MUST get adequate Protein

Second, this is a low carbohydrate, moderate protein, high fat lifestyle.  N0 . . . it is NOT a high protein diet! However, so many of my patients don’t eat enough protein that they feel like it is a “high protein diet.”

Protein is essential for the building and maintaining of muscle, connective tissue and a number of other enzymatic reactions in your body.  However, in patients who are morbidly obese [people with a body mass index (BMI) over 50], excess protein intake can cause fat to be stored by producing an excessive insulin response.  In these patients we initially moderate protein.  Excess sugars and a number of proteins, in the presence of a high insulin response, are converted to triglyceride (the soft squishy stuff inside the fat cells that make them plump) and stocked away inside your adipose tissue.  Excessive protein, especially the amino acids argenine, leucine and tryptophan are common ketosis killers, not because they are converted to sugar, but because they stimulate and insulin response all by themselves.

If you don’t fall into the morbidly obese category (BMI over 50). Then, I encourage you to use the protein levels below.

Initially, I ask my patients to focus on lowering their carbohydrate intake and I don’t really worry about protein.  (It is often hard enough to figure out what the difference between a carbohydrate and a protein in the first month or two if you’ve never had any nutrition background.)  Most people begin losing weight just by lowering carbohydrates over the first few months.  Once you figure out how to lower your carbohydrates, if your weight loss is not moving and your pants are not getting looser, then you’re probably eating too much protein.

How much protein do you need?  It’s pretty easy to calculate and is based on your height and gender.  Your basic protein needs to maintain muscle, skin and hair growth are as follows:

  • 70 grams or higher for women per day
  • 120 grams or higher for men per day.

However, these levels are WAY TOO LOW for weight loss and maintaining good health.  Because we now know that protein acts as a hormone in a number of ways, in my office I recommend women get 80-90 grams of protein per day, and men should get > 150 grams of protein per day.

ProteinIf you’re still a little confused about protein, read my article on Why Your Chicken Salad Stops Your Weight Loss.

This also goes for protein powders and protein shakes.  Many of these have 25-40 grams of protein in them per serving, so be careful with their use.

Nutritional Ketosis is a High Fat Diet

Third, this is a high fat lifestyle.  Yes, I want you to INCREASE your fat intake.  I’m going to repeat that, again, just for clarity, . . . . INCREASE your fat intake.  Increase it to around 50% of your total calories, . . . 70% of your total calories if you can do it.  Not enough fat is a common ketosis killer.

“What?! Won’t that cause heart disease and stroke and make my cholesterol worse?!!!”

I know, take a big deep breath . . . (you may even need to breath into a paper bag for a minute if you begin hyperventilating).

No, it will not raise your cholesterol, cause heart disease, or cause a stroke.  If you have lowered your carbohydrate intake to less than 20 grams per day, then there is NO hormonal signal for you to make more bad cholesterol, worsen heart disease, or cause a stroke.  In fact, there is great data showing that increasing your fat and lowering your carbohydrates reverses the blockage in the arteries.  I see this reversal every single day in my clinic through the application of ketogenic diets.

If we remove carbohydrate as your primary fuel, you must replace it with something else.Food Pyramid WrongThat something else should be fat.  Protein must be moderated, as it will also be stored as fat if you eat too much.  So, if the carbohydrates are kept low, fat intake can be increased and the body will pick the fat it wants and essentially throw the rest out without raising cholesterol, causing weight gain or causing heart disease.  This is why we want you to use good natural animal fats like butter, hard cheese, olive oil, coconut oil, avocado, etc.  Look for fats highest in omega-3 fatty acids as these decrease inflammation and improved weight loss.  Look for meats highest in fat like red meat (55% fat) and pork (45% fat).  Take the food pyramid and flip it over.

Check Your Sweeteners At the Door

The fourth common ketosis killer and culprit in halting your weight loss is  artificial sweeteners.  There are quite a few of them.  Most of them WILL cause an insulin response (exactly what we don’t want for weight loss) with minimal to no rise in blood sugar.  Raising blood sugar doesn’t matter, if the insulin is being stimulated  . . . “you’re gonna gain weight for the next 10-12 hours.”  I wrote an article for you to print off and hang on your fridge, upload it to your iPhone or carry it with you in your purse to the grocery store. (If you’re a man and you’re carrying a purse, please don’t tell me about it.)  You can find the article here: The Skinny About Sweeteners.  The short list of those sweeteners that are OK to use and cook with, and do not increase insulin response, can be found here in my Amazon Store.

Don’t Even Start with Coffee Creamers

CoffeeCreamersFifth on my list is coffee creamer.  Coffee creamer contains corn syrup solids (another very special name for  . . . SUGAR!!) and/or maltodextrin (SUGAR’s married name!).  If you must put something in your coffee, then use real heavy cream (pure tasty fat) or real butter.   It will taste much better (I’m told – I don’t drink coffee personally) and you won’t get an insulin spike 2-3 hours later and begin craving more coffee and donuts.

Yes, “Half & Half” is half fat and half sugar. . .  avoid it too!!

Ketosis Killing Medications

The sixth culprit in halting weight loss is medications.  Please talk to your doctor before making ANY changes in your medications as suddently stopping them can be hazardous to your health.  Those highest on my list for stopping your weight loss are Glyburide (glipizide), insulin, & steroids like prednisone.  A more complete list of medications that will halt your weight loss can be found on my on my ketogenic diet plan.  If you are on any prescription medications, please talk to your doctor or to a physician board certified in obesity medicine treatment about how to adjust or wean these medications in a way that is safe and appropriate for your individual needs.

Estrogen

The seventh common culprit in halting weight loss is a lack of estrogen in menopausal or post-menopausal women.  About menopause-cartoon-02420% of women that I see in my practice who are over 55 years old, need some degree of estrogen replacement before they are able to lose weight.  Estrogen plays a very large role in regulation of the metabolism and when deficient, causes weight retention or weight gain.  Talk to your doctor about the risks and benefits of estrogen for you individually in this situation.

Stress

The eighth reason for shifting out of ketosis is stress.  Acute and chronic stress can be caused by a number of issues. The most common is lack of sleep.  You can read about stress and ways to address it in two of my articles: How Does Stress Cause Weight Gain? and Adrenal Insufficiency, Adrenal Fatigue and PseudoCushing’s Syndrome – Oh My!

For many years, we’ve thought that caffeine was great for weight loss.  However, we are finding, clinically, that too much caffeine can also cause a stress response by raising cortisol, releasing glycogen, thereby stimulating an insulin response and bringing your weight loss to a screeching halt.  How much caffeine? . . . The jury is still out . . . and remains to be determined.  But, I am currently under going an n=1 experiment on myself (as many of you know, I loved Diet Dr. Pepper.  But I had to give it up).  I’ll keep you posted . . .

Look closely at these eight issues.  Correcting them usually solves most plateaus with weight loss and improves blood pressure, blood sugar and cholesterol control dramatically.

How Your Fruit and Your Alcohol Stop Your Weight Loss

Fruit & Alcohol Halt Weight Loss

Yes, your fruit makes you fat just like your beer gives you a beer belly. . .

It is fascinating how similarly fructose (the sugar in fruit) and alcohol are processed through the liver.  Both of them increase insulin and both increase triglyceride production as a byproduct of their metabolism.  This is clearly pointed out in Robert Lustig’s paper published in the Journal of the American Dietetic Association in 2010.

The metabolic pathways are very clearly outlined below:

Metabolism of Ethanol

Metabolism of Fructose

Cured . . . by Definition.

Cured Ham Low Carb Humor

A friend posted this image and I couldn’t help but think about this little cartoon throughout the day.  In the 15 years that I have been in medical practice, it was re-emphasized to me that my definition of cure and the patient’s definition of cure may at times be notably different or even in opposition.

I am reminded of a sweet a patient in her early nineties that was brought in by her three well meaning and very caring daughters.  This patient was a type II diabetic and, for the most part, her blood sugar was in pretty good control.  To put it in medical terms, her morning blood sugars were in the 120 range and her Hemoglobin A1c (HbA1c) was a 6.4%.  She was obese by the standards of her body mass index (BMI) and her cholesterol was elevated.

The concern of her three daughters, “there to rat her out,” as the patient put it, was that she was eating donuts for breakfast each morning for the last few months. I noted that her HbA1c had gone up from 5.9% at the last visit.  We discussed the fact that the change in her dietary intake appeared to have caused the rise in her blood sugar and her cholesterol.

With my affirmation of the cause as ammunition, the patient’s daughters began to individually take shots at her choice of meals over the last year. They did it, I could see because they loved and cared for heir mother.  But I noticed the patient’s demeanor change suddenly, and a bit of trust between me and my patient began to slip.

This sweet centenarian turned and looked at me, square in the eye, and then proceeded to give me an education.

“Dr. Nally, do you know how old I am?” she asked.

“Why, yes, you are 93 years old,” I replied.

“And do you know how much longer I am going to be alive on this earth?” she inquired.

“Well, no. I do not know how much longer you will be alive, but I can tell you that you have out lived most of your peers and the average age of most Americans.”

“Then, why the hell are you, and my daughters, worried about me eating a damn do-nut?” she yelled.  “My blood sugar is still pretty good and I figure that if I have to be around on this earth any longer, then by stars, I am going to enjoy my favorite breakfast. If it kills me, then so be it. I am going to enjoy it.”

Well, that was that.  The cure was to enjoy her last few years upon this earth.

She did just that.

The Fat Storage Control Mechanism

The only way to successfully loose weight is to modify or turn off the mechanisms that stimulate fat storage.  For years we have been told that this was just a problem of thermodynamics, meaning the more calories you eat, the more calories you store. The solution was, thereby, eat less calories or exercise more, or both. We are taught in school that a 1 gram of carbohydrate contains 4 kcal, 1 gram of protein contains 4 kcal, and 1 gram of fat contains 9 kcal.

It’s easy to see that if I’m going to limit my calories, cutting out fat is the first step.  For the last 65 years, we as a society have been doing just that, cutting out fat, exercising more and eating fewer calories.  What has it done for us? It’s made us fatter! (1)

World Obesity Rates
Obesity Rates Around the World

Some may argue that we really aren’t eating fewer calories and exercising more. But most people I have seen in my office have tried and tried and tried and failed and failed and failed to loose weight with this methodology. The definition of insanity is “doing the same thing over and over and expecting a different result.”

Most of my patients are not insane, they recognize this and stop exercising and stop restricting calories . . . ’cause they realized, like I have, that it just doesn’t work! If you’re one that is still preaching caloric restriction and cutting out fat, I refer you to the figure above and the definition of insanity . . .

So, if reducing the calories in our diet and exercising more is not the mechanism for turning on and off the storage of fat, then what is?

Before I can explain this, it is very important that you appreciate the difference between triglycerides and free fatty acids.  These are the two forms of fat found in the human body, but they have dramatically different functions.  They are tied to how fat is oxidized and stored, and how carbohydrates are regulated.

Fat stored in the adipose cells (fat cells) Triglycerides-and-Glycerol1as well as the fat that is found in our food is found in the form of triglycerides. Each triglyceride molecule is made of a “glyceride” (glycerol backbone) and three fatty acids (hence the “tri”) that look like tails. Some of the fat in our adipose cells come from the food we eat, but interestingly, the rest comes from carbohydrates

(“What! Fat comes from sugar?! How can this be?!!“)

de novo lipogenesis
De Novo Lipogenesis

We all know that glucose derived from sugar is taken up by the cells from the blood stream and used for fuel, however, when too much glucose is in the blood stream or the blood sugar increases above the body’s comfort zone (60-100 ng/dl), the body stores the excess. The process is called de novo lipogenesis, occurring in the liver and in the fat cells themselves, fancy Latin words for “new fat.”  It occurs with up to 30% (possibly more if you just came from Krispy Kream) of the of the carbohydrates that we eat with each meal.  De novo lipogenesis speeds up as we increased the carbohydrate in our meal and slows down as we decrease the carbohydrate in our meal. We’ve known this for over 50 years, since it was published by Dr. Werthemier in the 1965 edition of the Handbook of Physiology (2).

While we know that fat from our diet and fat from our food is stored as triglyceride, it has to enter and exit the fat cell in the form of fatty acids.  They are called “free fatty acids” when they aren’t stuck together in a triglyceride.  In their unbound state, they can be burned as fuel for the body within the cells. I like to think of the free fatty acids as the body’s “diesel fuel” and of glucose as the body’s version of “unleaded fuel.”  The free fatty acids can easily slip in and out of the fat cell, but within the adipose cell, they are locked up as triglycerides and are too big to pass through the cell membranes.  Lipolysis is essentially unlocking the glycerol from the free fatty acids and allowing the free fatty acids to pass out of the fat cell. Triglycerides in the blood stream must also be broken down into fatty acids Insulin and Triglyceridesbefore they can be taken up into the fat cells. The reconstitution of the fatty acids with glycerol is called esterification. Interestingly, the process of lipolysis and esterification is going on continuously, and a ceaseless stream of free fatty acids are flowing in and out of the fat cells.  However, the flow of fatty acids in and out of the fat cells depends upon the level of glucose and insulin available. As glucose is burned for fuel (oxidized) in the liver or the fat cell, it produces glycerol phosphate. Glycerol phosphate provides the molecule necessary to bind the glycerol back to the free fatty acids. As carbohydrates are being used as fuel, it stimulates increased triglyceride formation both in the fat cell and in the liver, and the insulin produced by the pancreas stimulates the lipoprotein lipase molecule to increased uptake of the fatty acids into the fat cells (3).

So when carbohydrates increase in the diet, the flow of fat into the fat cell increases, and when carbohydrates are limited in the diet, the flow of fat out of the fat cells increases.

Summarizing the control mechanism for fat entering the fat cell:

  1. The Triglyceride/Fatty Acid cycle is controlled by the amount of glucose present in the fat cells (conversion to glycerol phosphate) and the amount of insulin in the blood stream regulating the flow of fatty acid into the fat cell
  2. Glucose/Fatty Acid cycle or “Randle Cycle” regulates the blood sugar at a healthy level.  If the blood glucose goes down, free fatty acids increase in the blood stream, insulin decreases, and glycogen is converted to glucose in the muscle and liver.

These two mechanisms ensure that there is always unleaded (glucose) or diesel fuel (free fatty acids) available for every one of the cells in the body. This provides the flexibility to use glucose in times of plenty, like summer time, and free fatty acids in times of famine or winter when external sources of glucose are unavailable.

The regulation of fat storage, then, is hormonal, not thermodynamic. Unfortunately, we’ve know this for over 65 years and ignored it.

We’ve ignored it for political reasons, but that’s for another blog post . . .
