HOMA-IR Insulin Resistance Index

Calculate insulin resistance using HOMA-IR = (fasting insulin mU/L x fasting glucose mmol/L) / 22.5. Normal <2.0; insulin resistance 2.0-2.9; significant resistance 3.0+.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate insulin resistance using HOMA-IR = (fasting insulin mU/L x fasting glucose mmol/L) / 22.5. Normal <2.0; insulin resistance 2.0-2.9; significant resistance 3.0+

Each component has a specific meaning:

  • HOMA-IR = / 22 — The homa-ir = / 22 recorded for the scenario being assessed.

Note: Interpret the homa-ir result against the thresholds and context described above.

How to Use

Enter the HOMA-IR = / 22 for the scenario you are assessing. Calculate insulin resistance using HOMA-IR = (fasting insulin mU/L x fasting glucose mmol/L) / 22.5. Normal <2.0; insulin resistance 2.0-2.9; significant resistance 3.0+. Use the homa-ir result to inform your calculation.
