Keto-Mojo GKI Calculator
Track your ketosis level and metabolic health with one simple number.
How Keto-Mojo GKI Calculator Works
The Glucose Ketone Index (GKI) gives you a complete picture of your metabolic state by combining your blood glucose and ketone readings into a single ratio. Unlike looking at glucose or ketones separately, the GKI normalizes both values to show how deeply you're in ketosis.
This calculator takes your glucose reading (in either mg/dL or mmol/L) and ketone level (in mmol/L) to calculate your GKI score. Lower GKI values indicate deeper ketosis, which can be beneficial for weight loss, mental clarity, and therapeutic applications.
The GKI was originally developed to monitor therapeutic ketosis for medical conditions like epilepsy and cancer treatment. Today, it's widely used by people following ketogenic diets to optimize their metabolic health and track their progress more accurately than using glucose or ketones alone.
Keto-Mojo GKI Calculator Formula Breakdown
Formula
When glucose is measured in mg/dL: GKI = (Glucose ÷ 18.0182) ÷ Ketones
When glucose is measured in mmol/L: GKI = Glucose ÷ KetonesVariables Explained
- Glucose levelYour blood glucose concentration, typically measured 2-3 hours after eating using a glucose meter. You can find this value on most home blood glucose monitors or from lab tests. The timing matters since glucose levels fluctuate throughout the day based on meals, stress, and activity.
- UnitsThe measurement system for your glucose reading. Choose mmol/L if you're in Canada, Europe, or other countries using the metric system, or mg/dL if you're in the United States. Your glucose meter will display readings in one of these units.
- Ketone levelYour blood ketone concentration measured in mmol/L using a ketone meter and test strips. Blood ketone testing is more accurate than urine strips and provides a real-time snapshot of ketosis. Test at the same time as your glucose reading for the most accurate GKI calculation.
Example Calculation
Given:
- Glucose level: 4.6 mmol/L
- Units: mmol/L
- Ketone level: 2.0 mmol/L
Calculation:
Since glucose is already in mmol/L, use the direct formula
GKI = Glucose ÷ Ketones
GKI = 4.6 ÷ 2.0 = 2.30Result:
2.30Explanation
This example shows someone in therapeutic ketosis with a GKI of 2.30. This level indicates good metabolic flexibility and deep ketosis, suitable for therapeutic applications or aggressive weight loss goals. The person is likely following a strict ketogenic diet or practicing intermittent fasting.
Tips for Using Keto-Mojo GKI Calculator
- 💡Test your levels 2-3 hours after eating for the most accurate GKI reading, as testing too soon after meals can show temporarily elevated glucose.
- 💡Track your GKI at consistent times and conditions (same time of day, similar meals) to identify patterns and see how different foods or activities affect your ketosis.
- 💡If you're using GKI for therapeutic purposes like managing epilepsy or cancer treatment, work closely with your healthcare provider to interpret results and adjust your approach.
