GKI calculator
Enter glucose and ketones to get GKI and assess ketosis depth.
When to use
- •If you measure ketones and want to see the depth of ketosis.
- •If you follow therapeutic keto and need a zone indicator.
- •If you want to compare responses to different meals.
- •If you track recovery after workouts or stressful days.

How to read GKI
4#1
GKI = glucose (mmol/L) / ketones (mmol/L). Lower values mean deeper ketosis.
#2
Transitions between zones are gradual and depend on diet and activity.
#3
Look at patterns over multiple days rather than single readings.
#4
Compare under similar conditions: sleep, meal timing, and activity.
Tips
5Measure at the same time of day to compare.
Stress, sleep, and workouts can shift readings.
Use a similar fasting window before each measurement.
Log your context (sleep, stress, training) with each value.
Avoid overreacting to one outlier reading.
FAQ
4Do I need accurate meters?
Yes, meter accuracy affects GKI.
How often should I measure?
2–3 times per week is enough for tracking.
Why did GKI rise with the same carbs?
Sleep, stress, hydration, and recent training can all affect readings.
What is a good range?
It depends on your goal; consistency in ketosis is often more useful than chasing one number.
GKI is an indicator, not a medical diagnosis. Interpret based on your goals.
