The 20-Year Diabetes Blind Spot

Mark 0:26

So, what if the chronic disease that eventually uh kills millions of people actually starts like 20 years before a doctor ever even looks at your chart and tells you you're sick?

Rachel 0:36

Yeah, that is the reality.

Mark 0:38

Right. Because today we're looking at this massive medical blind spot. I think most of us just assume a metabolic condition like type 2 diabetes. It just hits you the exact day your blood sugar crosses that red line on a lab report. You know, you get the blood draw, the doctor frowns, and boom, you have a disease. But our mission for this deep dive is to completely tear down that assumption.

Rachel 1:01

Oh, absolutely.

Mark 1:02

We're jumping into this really paradigm-shifting framework from a detailed article published by Quick Lab Mobile, and it's all centered on the research of Dr. Isabel Cooper. Right. We're going to figure out why a totally normal blood test might actually be hiding this devastating metabolic struggle literally years or decades before the alarms go off.

Rachel 1:20

It really is a massive blind spot because in conventional medicine, we are just incredibly fixated on blood glucose.

Mark 1:27

Right, the blood sugar.

Rachel 1:28

Exactly. We look at fast and glucose, we look at hemoglobin A1C, but focusing entirely on glucose, it's kind of like judging the health of a sinking ship by measuring how dry the top deck is.

Mark 1:40

Oh wow.

Rachel 1:40

Right? While completely ignoring the pumps that are just working furiously below the water line to keep it afloat.

Glucose Numbers Hide Insulin Strain

Mark 1:47

Okay, let's unpack this because Dr. Cooper's framework completely changes the map here. She introduces this concept of metabolic phenotypes.

Rachel 1:56

Yeah.

Mark 1:56

Which basically shifts our entire focus away from just looking at the blood sugar to looking at the effort required to keep it there.

Rachel 2:02

Exactly. Her model shifts the spotlight to basal insulin and specifically how hard your pancreatic beta cells are working. So traditional medicine just asks, you know, what is the glucose level? Right. But Cooper's framework asks how much hormonal effort was required by the body to achieve that level.

Mark 2:19

Aaron Powell Yeah, and the article gives this really concrete example that I just couldn't stop thinking about. So picture two different people.

Rachel 2:24

Okay.

Mark 2:25

They both go to their annual physical, they both get their blood drawn, and they both get a fasting glucose result of exactly 90 milligrams per deciliter. Trevor Burrus, Jr.

Rachel 2:33

Right, which is a perfect textbook normal number. Any doctor would be thrilled with that.

Mark 2:37

Totally. They get a high five, they're sent on their way. But Cooper's framework looks under the hood. So person A maintains that perfect 90 score with just four microinternits per milliliter of insulin. But person B needs 18 units of insulin to keep that exact same reading of 90.

Rachel 2:56

Which is a staggering difference. I mean, the glucose looks absolutely identical on a piece of paper, but the metabolic reality for those two people is entirely different.

Mark 3:05

Right.

Rachel 3:05

Person B's body is working more than four times as hard just to stand still.

Mark 3:10

It makes me think of a duck gliding smoothly across a pond.

Rachel 3:14

Oh, I like that.

Mark 3:15

Above the water, the glucose level, everything looks perfectly calm and serene. But underwater, where the insulin is, that duck's legs are just frantically paddling at maximum speed to maintain that illusion of normalcy.

Rachel 3:27

Aaron Powell That is a perfect visualization, and it perfectly describes stage one of Cooper's framework, which she calls homoglycemic hyperinsulinemia.

Mark 3:36

Okay, that's a mouthful.

Rachel 3:38

It is, but let's break it down. So normoglycemic means normal blood sugar. Okay. And hyperinsulinemia means high insulin in the blood. So in this stage, the body is aggressively compensating. As your cells start to become a little bit resistant to insulin signal, the pancreas responds by just pumping out more of it.

Mark 3:56

So it just floods the system.

Rachel 3:58

Exactly. It floods the system to force the blood sugar to stay perfectly normal.

Mark 4:01

Okay, but wait, I have to push back here. I'm a little confused. We've always been told that insulin is the good guy, right? It's the medicine that diabetics literally have to inject to save their lives.

Rachel 4:11

Right, right.

Mark 4:12

So why are we suddenly framing high insulin as this secret toxic problem?

Rachel 4:18

Aaron Powell Yeah, that's a really common misconception and it's vital to clear up because insulin is a hormone, right? It's a chemical messenger, and primarily it's a storage hormone. Its job is to tell your cells, hey, we have energy in the bloodstream, open up and store it. Right. But hormones work on a principle of sensitivity. If you have too much of a hormone constantly bombarding a cell, the cell protects itself by downregulating its receptors. Right. It essentially puts in earplugs because the hormone is screaming too loudly. Oh, I see. Yeah. So while you obviously need insulin to live, chronic, constantly elevated insulin forces the body into this unnatural, constantly storing state, which eventually deafens the cells to the signal altogether.

Mark 5:01

Aaron Ross Powell So the cells are putting in earplugs and the pancreas responds by basically just grabbing a bigger megaphone.

Rachel 5:07

Precisely. And it works, well, for a while.

Mark 5:10

But since our metaphorical duck can't paddle at sprint speed forever, how long can someone actually stay in this silent stage one phase where everything looks fine?

Rachel 5:19

Potentially

Prediabetes Means Compensation Is Failing

Rachel 5:20

decades.

Mark 5:20

Decades.

Rachel 5:21

Yes. And this isn't just theoretical. The source material highlights this massive 24-year longitudinal study following adults who initially had perfectly normal glucose. Okay. The researchers found that high fasting insulin independently predicted future blood sugar issues years, even decades, before those blood sugar issues actually materialized. Wow. The elevated insulin was this blaring alarm, but nobody in standard cornical practice was listening because they were only looking at the glucose, which was still fine.

Mark 5:52

So under current medical guidelines, this person in stage one, with their pancreas working massive overtime, gets a totally clean bill of health.

Rachel 6:02

Exactly.

Mark 6:02

They are told to keep doing what they're doing, which means, wait, so when someone finally gets a prediabetes diagnosis, they aren't actually at the start of the disease. It's actually a late-stage warning.

Rachel 6:14

That is exactly the harsh reality. Prediabetes is not the beginning of the problem. It is the beginning of the failure to compensate for the problem. Man. Yeah. It marks the transition to stage two in Cooper's model. The duck is getting tired. The duck is exhausted. In stage two, the insulin is still very high. The pancreas is still screaming through that megaphone. But the body's tissues, specifically your skeletal muscle, your liver, and your adipose or fat tissue, they've put in so many earplugs that even massive amounts of insulin aren't enough anymore. Complete compensation has basically failed, and glucose finally starts escaping control, rising into that prediabetes range.

Mark 6:52

So the muscles which usually soak up that sugar are basically locking their doors. Yes. But if the doors are locked, where does the sugar go? And the liver's doing something really strange in this stage too, right?

Rachel 7:01

Aaron Ross Powell,

The Liver’s Selective Insulin Resistance

Rachel 7:02

What's fascinating here is how the liver exhibits a phenomenon called selective insulin resistance.

Mark 7:07

Selective.

Rachel 7:08

Yeah. In a healthy body, insulin tells the liver two distinct things. First, stop producing your own glucose because we just ate and we have plenty in the blood. Okay. Second, store any excess energy as fat. But in stage two, the liver becomes selectively deaf. It ignores insulin's signal to stop making glucose.

Mark 7:27

Wait, really?

Rachel 7:28

Yeah. So the liver stubbornly keeps pumping out new sugar into the blood even when it's already overflowing, but it completely obeys insulin's signal to keep storing fat.

Mark 7:37

That is wild. It's like an employee who blatantly ignores the boss, telling them to stop printing documents, but eagerly listens to the order to keep ordering more ink cartridges.

Rachel 7:48

Right.

Mark 7:48

You end up with a flooded office. So in the body, you get high blood sugar and a fatty liver at the exact same time.

Rachel 7:56

Exactly. And the liver doesn't just hold on to that fat, it starts exporting it. So you see a rise in triglycerides, which are the circulating fats in the blood, and an increase in blood pressure. So the cardiovascular risk is climbing steeply right here, well before a doctor ever says the word diabetes.

Mark 8:12

Okay, so if the liver is confused and pumping out sugar and the muscles have a brick wall up, the pancreas must be absolutely desperate.

Rachel 8:20

Oh, it is.

Mark 8:21

It's pumping out more and more insulin, getting zero response. That has to lead to some kind of system overload.

Rachel 8:27

It does. It leads straight

Glucotoxicity And Beta Cell Burnout

Rachel 8:28

into stage three, which is hyperglycemic hyperinsulinemia.

Mark 8:31

Okay.

Rachel 8:31

This is what we conventionally diagnose as full type 2 diabetes. High glucose despite having high insulin.

Mark 8:37

Let's pause on that. Despite high insulin, again, it feels so counterintuitive because the public perception is that diabetes means you just don't have enough insulin.

Rachel 8:44

Right. It's a relative deficiency, not an absolute one. A person in stage three often has significantly more circulating insulin than a healthy person.

Nicolette 8:52

Wow.

Rachel 8:53

But because the insulin resistance in their cells is so severe, that massive amount of insulin is functionally useless. And this creates an incredibly toxic internal environment. The body starts experiencing two major things: glucotoxicity and lipotoxicity.

Mark 9:10

Those sound bad, but what are they actually doing at a cellular level?

Rachel 9:13

Well, glucotoxicity is the chronic exposure to high glucose, which causes massive oxidative stress. Okay. Think of oxidative stress like biological resting. The excess sugar generates free radicals that literally damage the cellular machinery, rusting your blood vessels and tissues from the inside. Ouch. Yeah. Lapotoxicity is similar, but it's caused by chronically elevated free fatty acids in the blood. These fats start gumming up the internal workings of organs that were just never designed to store them.

Mark 9:42

So your body is basically marinating in a corrosive syrup of excess sugar and misplaced fat.

Rachel 9:48

It is deeply corrosive, and particularly to the beta cells in the pancreas. Which brings us to the final phase, stage four. Dr. Cooper calls this pseudotype 1 diabetes.

Mark 9:58

Pseudotype 1, because actual type 1 is an autoimmune condition, right? Where your body attacks itself and you can't make any insulin at all.

Rachel 10:05

Right, exactly. But in stage four of type 2 diabetes, it isn't an autoimmune attack. Instead, after years and years of this toxic stress and relentless overwork, the pancreatic beta cells undergo two terrifying processes. Oh boy. Dedifferentiation or apoptosis. Dedifferentiation means the cells are so stressed they actually regress and forget how to be insulin-producing cells.

Mark 10:28

They just forget.

Rachel 10:29

They lose their identity. And apoptosis means programmed cell death. The cells essentially commit suicide to save the surrounding tissue from the toxic environment. The pancreas just burns out.

Mark 10:39

Wow. It's like a car engine running in the red zone for 100,000 miles. You know, it might keep you moving down the highway for a while, but eventually the heat is too much, a gasket blows, the engine seizes up, and it just can't produce horsepower anymore, no matter how hard you press the gas pedal.

Rachel 10:54

That's a highly accurate analogy. The pancreas physically loses its capacity to manufacture insulin. And the article points out a very specific crucial test for this called C peptide.

Mark 11:05

Why C peptide and not just measuring the insulin itself?

Rachel 11:09

Because if a patient is injecting pharmaceutical insulin to manage their diabetes, a standard insulin test can't tell the difference between what they injected and what their body produced. Oh, that makes sense. But C peptide is different. When your pancreas manufactures its own natural insulin, it creates a larger precursor molecule that gets snipped in half. One half becomes active insulin and the other half is C peptide. Okay. So C. peptide is like the exhaust fume of natural insulin production. By measuring it, doctors can see if the body's engine still has natural reserves left or if it's truly burnt out. If C. peptide is very low while glucose is high, the pancreas has failed.

Mark 11:46

Okay, so staying with that engine analogy. If I blow a gasket in my car, I have to tow it to a mechanic to get it rebuilt. Can you unblow the metabolic gasket? I mean, can you actually put this progression in reverse?

Rachel 11:57

Aaron

Remission Beyond A1C Targets

Rachel 11:58

Powell Yes, but this brings up a crucial distinction in the medical world regarding the word remission. Standard clinical medicine defines remission mostly by the glucose outcome. The rule is generally if you can keep your A1C below 6.5% for three months without taking any glucose-lowering medications, you are technically in clinical remission.

Mark 12:20

Which sounds like a total victory.

Rachel 12:21

It is a victory, but Cooper's physiological definition of remission is much stricter. And it goes back to the difference between just looking at the top of the sinking ship versus looking in the engine room.

Mark 12:31

Because you could be faking it. Like you could have a normal glucose number again, but underneath you're still paddling like crazy.

Rachel 12:37

Exactly. The text gives a really stark comparison. Imagine two people who both achieve an A1C of 5.8% without medication. Standard medicine looks at the paperwork and says they are both in remission, high fives all around. But if we measure their insulin, we see the truth. The first person has completely normal, low insulin responses, but the second person still requires massive, skyrocketing insulin spikes every time they eat just to wrestle that glucose down to 5.8%.

Mark 13:08

So the first person has actually fixed the underlying engine. They are what we call metabolically flexible.

Nicolette 13:13

Right.

Mark 13:13

But the second person is just back in stage one. They are quiet, they look fine on a basic lab test, but they are incredibly fragile, just waiting to relapse the second they eat a heavy meal or get stressed.

Rachel 13:24

This raises an important question: how do we fix the root cause rather than just forcing the glucose number down? If we want true physiological remission, or better yet, to avoid this entire nightmare process from the start, we have to look at what drives the insulin resistance in the first place.

Personal Fat Threshold And Ectopic Fat

Mark 13:42

And the article points a big flashing arrow directly in our fat cells, but it makes a really important distinction, which is it's not just about the total amount of fat on your body, it's about where that fat is being stored.

Rachel 13:52

Yes, this is the concept of the personal fat threshold. We have subcutaneous fat, which is the fat just under your skin. From a metabolic standpoint, subcutaneous fat is actually a safe storage depot. It's designed to keep excess energy safely tucked away so it doesn't harm your organs. Okay. But every single person has a genetic, individualized limit to how much their subcutaneous fat cells can expand.

Mark 14:17

Like a bathtub filling up with water. Some people have massive bathtubs, some have tiny ones.

Rachel 14:22

Right. And when that bathtub overflows, the energy has to go somewhere. It spills over as ectopic fat. Ectopic literally means out of place. So the fat starts accumulating in places it was never designed to be, like wrapping around your liver, infusing into your skeletal muscle, and burying into the pancreas itself. This ectopic fat is what severely interferes with insulin signaling. It physically gums up the receptors. It is the primary driver of the resistance.

Mark 14:48

Here's where it gets really interesting because this detail in the text completely reframed how I look at exercise. The article talks heavily about skeletal muscle, noting that muscle is responsible for the vast majority of glucose disposal after a meal. It's basically our body's primary storage tank for sugar.

Rachel 15:06

Right.

Mark 15:06

So if muscle is our main sink, being sedentary isn't just a generic, unhealthy lifestyle choice. It's actively shrinking our body's physical capacity to handle the food we eat.

Rachel 15:18

That is the exact mechanism. When you lack muscle mass, or when the muscle you do have is inactive or marbled with that ectopic fat, you're presenting the pancreas with a much smaller, highly resistant reservoir. The pancreas has to pump out significantly more insulin to force the glucose into a smaller, stubbornly locked space.

Mark 15:38

So to expand the size of the tank, we need resistance training. Building muscle quite literally builds a larger disposal site for your blood sugar.

Rachel 15:45

Yes, and it's even better than that. Contracting muscle, meaning lifting weights or doing strenuous exercise, can actually take up glucose through entirely different pathways that don't even require insulin. So resistance training acts like a bypass valve for the whole system, but the text also highlights other key interventions.

Muscle Sleep And Lower Carb Levers

Rachel 16:03

Sleep is a massive one.

Mark 16:05

Wait, really? What does sleep have to do with my blood sugar?

Rachel 16:08

It has everything to do with cortisol, your body's primary stress hormone. When you are sleep deprived, or if you suffer from sleep apnea, your body interprets that as a state of constant emergency. Okay. Cortisol is a fight or flight hormone. Its job is to say, we are in danger, we need immediate energy. So cortisol signals the liver to dump stored glucose into the blood while simultaneously telling your muscles not to use it, saving it for the brain to deal with the threat. If you're chronically sleep deprived, you are constantly bathed in the survival signal, which makes you deeply insulin resistant.

Mark 16:45

That's terrifying. So you could have a perfect diet, you could be hitting the gym every day, but if you're sleeping like four hours a night, you're chemically forcing your body to act like it's diabetic.

Rachel 16:54

Absolutely. And then, of course, the text focuses heavily on carbohydrate reduction. By reducing the raw amount of dietary glucose coming into the system, you drastically lower the immediate demand on the pancreas. You stop asking it to sprint. And when insulin levels finally drop, the body can shift gears into lipolysis. Lipolysis, which is the breakdown and burning of stored fat.

Mark 17:16

So it stops shoving fat into the liver and starts actually burning it for fuel.

Rachel 17:20

Precisely. And as a byproduct of burning that fat, the liver starts producing beta-hydroxybutyrate, which is a key ketone body. Beta hydroxybutyrate isn't just a fuel, it's an incredibly clean, efficient energy source for the brain and the heart.

Mark 17:35

Nice.

Rachel 17:35

Dr. Cooper points to this restoration of nutritional ketosis, the presence of these ketones, as a powerful, verifiable sign that the hyperinsulinemia is actually reversing and the engine is healing.

Mark 17:46

Okay, so we know what causes it. We know the mechanisms of how to reverse it. I guess

Tests That Catch Risk Early

Mark 17:50

the million-dollar question is how do we test for this before the glucose fails? Because we firmly established that a standard A1C and a fasting glucose test are basically just looking at the smoke, not the fire.

Rachel 18:01

Right. Standard tests are necessary, but entirely insufficient on their own. To see the fire, you need to measure fasting insulin alongside fasting glucose. When you have both of those numbers, you can calculate what's called your H A I I R the homeostatic model assessment of insulin resistance.

Mark 18:20

Yes. The math in the article involves multiplying the glucose by the insulin and dividing by a constant, 405. But the math isn't really the point for the listener, is it?

Rachel 18:29

No, no, you don't need to memorize the formula. What you need to understand is what the math represents. It is a ratio of the outcome compared to the effort. It measures how much insulin it took to keep your glucose where it is. If the effort is sky high, your HOMA IR score flashes red, warning you of severe insulin resistance, even if your glucose number looks absolutely pristine.

Mark 18:48

That ratio alone feels like it should be standard practice at every physical. But the text also goes into the Kraft style oral glucose tolerance test. How is that different from the normal, nasty, sugary drink test they give pregnant women or patients at risk?

Rachel 19:03

In a standard glucose tolerance test, you drink 75 grams of liquid glucose, and the doctor measures your blood sugar over two hours. If the sugar goes up and comes back down to normal, they say you passed. But Dr. Joseph Kraft revolutionized this decades ago by measuring the insulin at those exact same time intervals.

Mark 19:22

Uh, looking under the water.

Rachel 19:24

Exactly. He discovered that in thousands of patients, the glucose stayed totally normal and they passed the standard test, but their insulin spiked to astronomical levels and stayed elevated for hours just to achieve that pass. He called this hidden pathology diabetes in situ, meaning the disease was fully present, just concealed by the body's massive compensatory effort.

Mark 19:44

Incredible. And the article suggests one more piece of the puddle, testing APOB for cardiometabolic risk. We touched on this earlier, but clarify what APOB actually tells us.

Rachel 19:53

APOB, or APOLIPO protein B, is a protein found on the surface of atherogenic particles. Okay. These are the dangerous cholesterol-carrying particles that actually crash into and embed themselves in your artery walls, causing plaques and heart disease.

Nicolette 20:07

Yikes.

Rachel 20:07

When insulin is chronically high, the liver pumps out a massive number of these particles. Testing APOB gives you a much clearer, direct picture of the cardiovascular damage that is developing in lockstep with the hyperinsulinemia.

Mark 20:21

So it all ties together.

Rachel 20:22

Yes. By combining these tests, the omin AIR ratio, the Kraft style insulin patterns, APOB, and the C peptide exhaust fumes, you can map exactly where you are on Cooper's continuum.

Mark 20:33

So

Demand Prevention Not Crisis Care

Mark 20:34

what does this all mean? If you're listening to this right now and thinking about your next annual physical, this deep dive should fundamentally change how you walk into that doctor's office. A normal glucose test is just the outcome. It's the top of the ship. You have to start asking your doctor about the effort your body required to achieve it. You have to demand they look under the hood.

Rachel 20:53

The overarching takeaway from all of this research is that catching this process in stage one, the hyperinsulin mic phase, offers a massive golden window of opportunity. The body's compensation mechanisms are still intact. If you intervene then by reducing the carbohydrate demand, preserving and building your muscle mass, prioritizing your sleep, and clearing out that ectopic fat, you can halt the progression entirely. You can turn the ship around before any permanent damage is done to the pancreas.

Mark 21:21

It is incredibly empowering to know that we don't just have to passively sit around and wait for the red line to be crossed on a lab report, but it also leaves me with a deeply provocative thought to chew on.

Rachel 21:32

Oh yeah.

Mark 21:33

Yeah, I mean, if decades of longitudinal science prove that testing fasting insulin can catch metabolic failure 20 years before blood sugar actually rises, why do our standard healthcare and insurance models still stubbornly wait for glucose to fail before diagnosing a problem?

Rachel 21:47

That is the question.

Mark 21:48

Are our medical systems economically incentivized to wait for a full-blown crisis to treat rather than investing in true early prevention? Just imagine how the entire landscape of modern medicine would shift if insurance covered the pursuit of metabolic efficiency rather than just managing its collapse.quicklabmobile.com.

Nicolette 22:26

Stay informed, stay healthy, and we'll catch you in the next episode.
