Glucose-Ketone Index Calculator
The Glucose-Ketone Index Calculator estimates your metabolic state by analyzing your blood glucose and ketone levels. This tool helps individuals on a ketogenic diet track their ketosis depth for optimal health benefits. Whether you are managing a medical condition, trying to lose weight, or improving athletic performance, this calculator offers precise insights into your metabolic flexibility.
How Glucose-Ketone Index Is Calculated
The Glucose-Ketone Index (GKI) represents the ratio between your blood glucose levels and ketone levels. It helps determine the primary fuel source your body is using for energy.
GKI = (Glucose in mmol/L) ÷ (Ketones in mmol/L)
Where:
- Glucose in mmol/L = Blood glucose converted to international units
- Ketones in mmol/L = Blood ketone level in international units
First, convert your glucose reading to mmol/L. This standardizes the units, ensuring an accurate comparison with your ketone level. Next, divide the glucose value by the ketone value. The result indicates how dominant ketones are in your system compared to sugar. This calculation provides a clear picture of your metabolic health and ketosis depth.
What Your Glucose-Ketone Index Means
Your GKI score reveals how deeply you are in ketosis and how efficiently your body is burning fat. A lower number generally means your body is producing more ketones relative to glucose.
Therapeutic Ketosis: Aim for a GKI between 1.0 and 3.0. This range is often used by patients managing specific health conditions like epilepsy or type 2 diabetes to reduce seizure activity or improve blood sugar control.
Moderate Ketosis: A score of 3.0 to 6.0 is effective for general weight loss, reducing inflammation, and improving mental clarity. It is a sustainable target for most healthy adults.
Deep Ketosis: A score below 1.0 is usually reserved for advanced practitioners or specific therapeutic protocols. It indicates maximum fat burning.
Important: Readings can fluctuate based on hydration, stress, or recent exercise. Always take measurements in a fasted state for the most consistent results.
