A1C is your 3-month average glucose. Both people below pass as normal. Now look at insulin, your fat storage hormone.
PancreasWorking hard
PancreasHardly working
Both have normal blood sugar. Neither has diabetes. One is making 8 times more insulin to keep it there.
How long can a pancreas keep that up?
Diabetes "runs in the family." So do family dinners. Before you blame your genes, check your fasting insulin, the test that isn't on any panel.
Insulin resistance was described in 1936: cells need more insulin to do the same job. Like a drug tolerance, it takes more to get the same effect. If you never measure it, you never have to explain it. How did we lose our way?
Let me show you what awareness can do.
The Unscripted Pharmacist
About me
I'm a pharmacist and a diabetes educator. Over 35 years inside the system. I taught the only diabetes education insurance would pay for. It failed. So I started measuring my own metabolism. I changed, and lost 50 pounds. My learning has made all the difference. I had to share it with everyone.

Pick your glucose level.
Select your fasting insulin. See the shadow.
Dr. Joseph Kraft, a pathologist, found people who would pass a glucose test and still had high insulin. That's insulin resistance in broad daylight.
Supporting evidence
Normal glucose is not a quiet pancreas. In one database of 4,185 people with normal glucose, about half, 2,079, were making too much insulin anyway.

A second group gave 5,340 people the sugar drink and watched their blood for two hours. Every person in this part had normal glucose. Sorted by their insulin, the high-insulin people handled that drink the way people with new diabetes did. The insulin explained it. The glucose did not.
No organization has set a cutoff for that test. This is not a screening result and it does not sort anyone into a group. It is a signal the standard panel does not carry.

Measure it
One sensor, one breakfast. Chris's oatmeal and fruit: the spike, then the crash two hours later.

Start here
One blood draw is a photograph. A sensor is the movie. Wear it for two weeks. No prescription needed.
Then
Your sensor shows glucose, not insulin. Most states let you order it yourself.
Then
The free 14-day CGM lab that goes with the book. The book shows you why. The Lab shows you how to see it in your own body.
Know your numbers before you choose.
Free
The free 14-day CGM lab that goes with the book. A lab of one. You.
Sense. Learn. Change.
Two weeks. Your body. Your data.
Your A1C is a 3-month average. A sensor shows you the whole movie.
In 14 days you learn to:
One email a day. Free. No sensor? A ketone meter works too.
I take no money from sensor or lab companies.

Is this book for you?
Against the Current: A pharmacist's guide to reversing what medicine calls permanent.
Read it. Measure it. Get off the medical merry-go-round.
On a glucose-lowering medication? Read this first.
This is not for you if you have type 1 diabetes, kidney disease or advanced liver disease. Or if you are pregnant or breastfeeding, are under 18, or have a history of disordered eating or a hospital stay for eating.
Hunger or craving? A craving comes and goes. Hunger that stays for 30 minutes is your body telling you to eat.
A sensor can read low when it is not. Lying on it can show a false low. So can fasting and very low carb. Confirm a low with a finger stick. If you have symptoms, treat it first the way your prescriber told you, then confirm.
Get help now: a low with shaking or sweating. Confusion, or someone says you seem off. Vomiting, fruity breath, or deep fast breathing.
If food starts to feel scary, take it off and come back another time.
Taking a glucose-lowering medication?
On insulin or a sulfonylurea (glipizide, glyburide, glimepiride)? Those cause lows. Talk with your prescriber before you change how you eat, and follow their plan for a low.
On an SGLT2 inhibitor (empagliflozin, dapagliflozin, canagliflozin, ertugliflozin)? Talk with your prescriber before you cut carbs or fast. Low carbs and low fluids have both been linked to hospital stays on this drug while the glucose reading looked ordinary.
