Insulin resistance
Insulin resistance is a state in which cells respond less to insulin, so the pancreas produces more of it to compensate. It sits underneath a large share of cardiometabolic problems — and it is usually followed with a handful of accessible measurements.
What it is
After a meal, glucose in the blood rises. The pancreas releases insulin — the hormone that unlocks cells so they can take up glucose and use it for energy. With insulin resistance, cells respond more weakly to that signal.
The body compensates by producing more insulin. That is why blood sugar can still look normal in the early stages while insulin is already elevated. It is also why a single measurement says little — the combination of several values says more than any one of them.
Insulin resistance is regarded as a risk state rather than a diagnosis in itself. Whether it is present, how pronounced it is and what it means in a particular case is for a physician to judge from tests and the whole picture.
Why it gets attention
Insulin resistance is associated with a range of other cardiometabolic conditions — prediabetes and type 2 diabetes, metabolic syndrome, raised blood pressure, lipid abnormalities, and fat accumulating around the organs and in the liver.
The other reason is practical: it is one of the states where daily habits have a measurable effect. The measurements that describe it move — and that movement shows up in data gathered over months, not in a single reading.
What influences the tracked measurements
Research consistently links several areas of daily life with the values below. This is general information, not a personal plan — specific targets and steps are set with a physician, especially with an existing diagnosis or medication.
- Movement — regular aerobic activity and strength work engage the muscles, which are the body's main consumer of glucose.
- Food — the amount and type of carbohydrate, fibre and protein intake, meal frequency.
- Sleep — short and broken sleep is associated with worse values after only a few nights.
- Waist circumference — fat around the organs is more closely tied to metabolic risk than total weight.
- Stress and alcohol — both affect blood sugar and sleep quality.

Which measurements are tracked
Insulin resistance is usually followed with blood-test values combined with body measurements. The lab values come from a blood test; weight and body composition come from a home scale or a watch.
How tracking it in one place helps
Cardiometabolic brings readings from your connected devices, your lab results and your own journal into one picture: how the measurements move across weeks and months, what changed, and which questions are worth asking. The analysis is AI-assisted and advisory, not diagnostic. You can grant view access to a physician or a relative — read-only and only with your explicit consent, which you can withdraw.

Frequently asked questions
Can a watch or a scale measure it?
No. Insulin resistance itself is assessed from blood tests — glucose, insulin, HbA1c and the indices derived from them. A watch and a scale provide the context around those: weight, body composition, sleep, activity, resting heart rate. The combination is what shows the direction over time.
Is it reversible?
For many people the measurements improve with changes in daily habits, and for some they return within the reference range. How far and by what means is a physician's judgement for the individual.
How is it different from prediabetes and type 2 diabetes?
They are different points on the same spectrum. Insulin resistance describes the weakened response of cells to insulin; prediabetes and type 2 diabetes are diagnoses a physician makes from specific blood sugar and HbA1c values.
What is useful to bring to a physician?
Your most recent blood test results and the history of your measurements — weight and body composition, blood pressure, sleep and activity over recent months. The trend over time is usually more informative than a single reading.
