Following his studies, many other studies have shown a decrease in glucose uptake and tumor size when the GKI is approximately 1.0 mmol/L (1, 2).

GKI for Weight Loss and Wellness

On the other hand, there are not really studies that show GKI is necessary for weight loss and wellness. However, many people watch their glucose levels to avoid high blood sugars AND monitor ketone levels to reach ketosis. For them, the glucose ketone index serves as an easy way to monitor their current level and progress.

By choosing a target goal number based on personal goals, one is able to make Keto Zone a long-term lifestyle with some flexibility depending on how the body reacts to the Keto Zone diet.

How to Calculate Glucose Ketone Index (GKI)?

To calculate your GKI:

  1. Follow the instructions or both the glucose meter and ketone meter. Record each number.
  2. IF YOUR GLUCOSE METER SHOWS MG/DL FOR UNITS (U.S.): Next, divide your glucose number by 18 (this converts the US reading, which is in mg/dL to the international units which match ketones, mmol/L). If you’re outside the US and/or use a meter that shows mmol/L, skip this step.
  3. Divide your glucose mmol/L number by your ketone number. This is your GKI.
  4. Use this number to monitor your progress and the GKI level. While different numbers correlate to different levels of ketosis, in general, the lower the number the better.

What does Your GKI Number Mean?

After following the steps listed above, use this guide to determine if you’re meeting your GKI:
  • GKI >9: You have not reached ketosis.
  • GKI 6-9: You’re at a low level of ketosis. This can be a good goal level for weight/fat loss and overall wellness.
  • GKI 3-6: Moderate level of ketosis. Ideal for those weight diabetes, obesity, metabolic syndrome, insulin resistance, etc.
  • GKI <3: This is a therapeutic ketosis level that is ideal for those who are fighting cancer, Alzheimer’s disease or Parkinson’s, epilepsy, etc.
