The basic formula used to calculate the glucose ketone index is:
Glucose Ketone Index = Glucose (mmol) / Ketones (mM)

How to Use the GKI Calculator
- Use a glucose meter to measure your blood glucose levels
- Use a ketone meter to measure your blood ketone levels
- Enter your blood glucose result number into the calculator in either mg/dl or mmol/L
- Enter your blood ketone result number into the calculator
- Click calculate for the formula to run and display your glucose ketone index result
- We recommend to use a good blood ketone meter like the Keto Mojo meter to be able to easily measure both your blood glucose values and β-OHB ketone values at home, or anywhere.
- Listen to the BioHackers Lab interview with Dr Nasha Winter where she explains her personal cancer story and Dr Winters’ explains what does the metabolic management of cancer mean.
Frequently Asked Questions
What Is the Glucose Ketone Index?
The Glucose Ketone Index is a ratio of blood glucose to ketones as a single value.
Why Was the Glucose Ketone Index Developed?
The GKI was originally developed as a simple research tool to help monitor the therapeutic efficacy of metabolic therapies in preclinical animal models and in clinical trials for the metabolic management of brain cancer.
How Do You Calculate GKI?
To be able to calculate your Glucose Ketone Index you first need to measure your blood glucose and blood ketones.
What is the GKI Formula?
The GKI calculation formula is to take your glucose levels measured in mmol/L result and divide that by your blood ketone levels measured in mmol/L result to get the final GKI number result.
What Is a Good GKI Result?
A good GKI result is between 1 and 2 for humans, which is hypothesised as when the zone of metabolic management is likely entered. GKI values that approach 1.0 are potentially the most therapeutic in the metabolic management of certain cancers according to the original GKI research paper authors.
When Should You Test Your GKI?
The optimal time to test your glucose and blood ketone levels needed for your GKI calculation is 2 to 3 hours after eating (postprandial).
How Often Should You Test Your GKI?
You should calculate your GKI values twice a day to be able to track how often you fall within the predicted target zone for metabolic management. This should be done under medical supervision.
