Insulin Sensitivity Index (Quick HOMA Interpretation)
Calculate your metabolic score and insulin sensitivity percentage. Includes lifestyle recommendations based on insulin resistance levels.
About
Metabolic health hinges on how efficiently cells respond to insulin. High sensitivity allows the body to process glucose with minimal hormonal effort. Low sensitivity, or resistance, forces the pancreas to overcompensate. This creates a state of chronic hyperinsulinemia often preceding Type 2 Diabetes.
This tool inverts standard resistance models to provide a Sensitivity Score. It translates clinical data into a percentage relative to a healthy baseline. The calculation relies on fasting values. Accuracy demands samples taken after at least 8 hours without caloric intake. Interpretation focuses on optimization for athletic performance and longevity rather than solely diagnosing pathology.
Formulas
The core calculation derives from the homeostatic model assessment (HOMA). Sensitivity is the reciprocal of resistance.
Insulin Resistance (HOMA-IR):
Ifasting × GfastingCInsulin Sensitivity (%S):
100HOMA-IRWhere I is Insulin (µIU/mL) and G is Glucose. The constant C depends on units (405 for mg/dL, 22.5 for mmol/L).
Reference Data
| Score (%) | Zone | Metabolic State | Action Plan |
|---|---|---|---|
| > 100 | Optimal | High Sensitivity | Maintain current hypertrophy/cardio split. |
| 70 − 100 | Good | Normal Response | Monitor refined sugar intake. |
| 40 − 69 | Warning | Early Resistance | Consider low-carb or intermittent fasting. |
| 20 − 39 | Poor | Significant Resistance | Structured caloric deficit required. |
| < 20 | Critical | Metabolic Syndrome Risk | Immediate medical consultation advised. |
