Flat and boring


Hey Reader, Dr Karl here.

Flat and boring.
If you have ever worn a continuous glucose monitor, you already know what I am about to show you, and you probably did not know it was the point.

Four years ago her CGM trace was jagged. Peaks, drops, more peaks. Today it is a low flat line that barely moves all day.

Flat and boring. That is the target. I have been saying it since before CGMs were fashionable, and I still say it.

Put two people in front of the same ice cream cone. Both spike. But the insulin resistant one goes up higher and stays up. The other one rises like a sea swell and comes back down. Same food, two completely different curves. Give them both a slice of pizza and the difference gets worse: one is back to baseline in an hour, the other is still elevated hours later.

That is what insulin resistance is.

It is not a number. It is a shape. It is the inability to come back down.


Here is the part I like about the CGM and why I ask for one when it is available. People cannot fake it. Someone can eat carefully the day before a blood draw. Nobody eats carefully for twelve straight days without it showing. I can eyeball a two-week trace and tell you which side of the line you are on before I look at a single lab value.

Her body did not just get better numbers. It changed what it believed about itself. Four years ago it was running the insulin resistant program. Now it runs the other one.

The traces are on screen in the video at about the three minute mark.

Hey Reader, Dr Karl here. Nine point six. That is where her fasting insulin sat four years ago. On a Labcorp range runs 2.6–24.9 µIU/mL so 9.6 prints without a flag. Nobody called. Nothing was said.Four years later it is 3.4.Her glucose came down 16 points, from 108 to 92. Her CRP fell from 3.6 to 0.47, which is an 87 percent drop. She was 35 pounds over her ideal body weight and she is now 24. No medication for any of it. She takes progesterone for a twenty-year history of endometriosis,...

Hey Reader, Dr Karl here. It shows up in the data, and it's the opposite of what most people track. When I plot my clients by age, something shows up that I didn't go looking for. The older people in my data — the ones still healthy, still going — have a much lower fasting insulin. Not lower cholesterol. Not lower weight, particularly. Big difference between fasting Insulin levels between Insulin Resistant people versus Non Insulin Resistant ones. Lower insulin. The same pattern shows up in...

Hey Reader, Dr Karl here. It predicts dementia and heart disease. Almost nobody orders it.And he got Fired from his lab at Harvard when no one would support his research. In the late 1990s a researcher named Kilmer McCully was working at Harvard on a marker called homocysteine. He thought it explained a great deal about heart disease — more, in some cases, than cholesterol did. That was the wrong thing to be right about ... and the wrong place to be right about what he discovered. He lost his...
