how to measure insulin resistance

Insulin resistance can be measured and evaluated through several methods, focusing primarily on how well your body handles glucose. Here are some insights shared on the Huberman Lab regarding measuring insulin resistance:

1. Blood Biomarkers: One method involves monitoring blood biomarkers such as insulin levels. When insulin resistance occurs, the body compensates by producing more insulin to help manage blood sugar levels. Over time, elevated insulin levels can become a key indicator of insulin resistance 1.

2. Fasting Blood Glucose Test: This test measures blood sugar levels after an overnight fast and helps to assess how well your body maintains blood sugar levels when not affected by recent meals.

3. Oral Glucose Tolerance Test (OGTT): This involves taking a glucose drink and then measuring blood sugar levels at various intervals. High levels in the blood after two hours can indicate insulin resistance 2.

4. HbA1c Test: This test gives an average blood sugar level over the past 2-3 months and can help in assessing long-term glucose management.

5. Homeostasis Model Assessment of Insulin Resistance (HOMA-IR): This is a mathematical method using fasting blood glucose and insulin levels to quantify insulin resistance.

Additionally, other lifestyle and physiological factors also play roles. For example, inactivity greatly influences the development of insulin resistance, while regular exercise can mitigate it. Sleep deprivation has also been shown to significantly impair glucose disposal, effectively inducing insulin resistance in as little as one week 2.

Understanding these tests and markers can provide a comprehensive picture of one's metabolic health and potential insulin resistance.
