FAQ
5Short answers to common questions about calculations and interpretation.
Do 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.
Can I use urine or breath ketones?
For GKI, blood ketone values are preferred because they are the most directly comparable with blood glucose.
