What Is Insulin Resistance and Why Does It Matter?

Did you know your blood sugar can be completely normal and you can still have insulin resistance? In this episode, we break down exactly what insulin resistance is, how it quietly progresses to prediabetes and type 2 diabetes, and why so many people don't find out until significant damage has already been done. Using a few good analogies and a little mini medical school, we make the science accessible without losing the substance.

We walk through the risk factors — from excess visceral fat and low muscle mass to age, family history, ethnicity, gestational diabetes, and medications — and explain how to interpret the lab values your doctor uses to diagnose prediabetes and type 2 diabetes, including fasting blood sugar and hemoglobin A1C. With over 115 million Americans living with prediabetes and 80% unaware, this is information that could genuinely change the trajectory of your health.

Key Takeaways:

• Insulin resistance can exist long before blood sugar becomes abnormal
• The progression from insulin resistance → prediabetes → type 2 diabetes is gradual and largely preventable
• Fasting blood sugar and hemoglobin A1C are the primary tools used to diagnose prediabetes
• Risk factors include excess abdominal fat, sedentary lifestyle, age, family history, and certain medications
• Early lifestyle changes make the biggest difference — and it's not too late
