GKI Calculator

The Glucose Ketone Index (GKI)

The glucose ketone index (GKI) is a single number that gives you a way to monitor the state of your metabolic health. Tracking your ketones lets you know how far you are into ketosis, and the GKI gives you a picture of the relationship between your ketone levels and your glucose levels. It’s simply an even more efficient way to see where you stand with your health.

  • Anything above 9 means your body has not transitioned into a fat-burning state.
  • A 6-9 GKI demonstrates a low level of ketosis: This is appropriate for those who want to lose weight or maintain optimal health.
  • A 3-6 GKI demonstrates moderate levels of ketosis: This is appropriate for addressing many common metabolic diseases including insulin resistance, Type 2 diabetes, or obesity.
  • A less than 3 GKI is a high level of ketosis: This is typically used for addressing epilepsy and cancers. Entering this high level of ketosis periodically each year can be beneficial for anyone hoping to use ketosis for disease prevention.

To get the most benefits from ketosis, you want to get your GKI number as low as possible.

While you may use the GKI simply to tweak your macro guidelines, this measurement can als be used in a wide range circumstances, including:

  • Cancer Treatment: Researchers first used the GKI in the treatment of different cancers, especially brain cancer.
  • Diabetes Treatment: The index has been used with metabolic therapy for both the prevention and treatment of Type 2 diabetes and Type 1 diabetes.
  • Fasting: The GKI is a tool to see how your body responds to fasting, and whether intermittent fasting helps you enter ketosis.
  • Athletic performance: Those looking to increase their sports performance can use the index to see how their body responds to using ketones, rather than glucose, during competition.
