How to Test for Insulin Resistance on Your Own

Why Your Doctor’s Tests May Not Be Enough

When it comes to diagnosing insulin resistance, most doctors rely on fasting blood sugar and A1C tests—usually conducted once or twice a year. Unfortunately, these tests often fail to catch insulin resistance in its earliest stages.

If you’re overweight, struggle to lose weight, have a family history of diabetes or prediabetes, or are experiencing low energy, you may already be insulin resistant and not even know it.

The good news? You can take action right now, on your own.

The Best Way to Detect Insulin Resistance: Try a CGM

Continuous Glucose Monitors (CGMs) provide real-time blood sugar tracking, offering insights you simply won’t get from occasional lab work.

With a CGM, you can:

See if your morning blood sugar is elevated (a common early sign of insulin resistance)
Track blood sugar spikes after meals
Identify prolonged periods of high blood sugar
Understand your body’s unique blood sugar patterns

This detailed information can help you prevent or reverse insulin resistance before it leads to prediabetes or type 2 diabetes.

CGMs Are Affordable and Easy to Use

CGMs are now available over the counter, without a prescription, and cost about $50 for two weeks of data. Many people who have used CGMs describe the experience as eye-opening and life-changing.

If you’re serious about improving your metabolic health, managing your weight, or reducing your risk of type 2 diabetes, a CGM is one of the best investments you can make in your health.
