What is Glucose Ketone Index (GKI) and why should you measure it?

The glucose ketone index (GKI) helps you understand the relationship between your glucose and ketone levels and the overall state of your metabolic health.

For those with metabolic problems, it is crucial to keep your metabolic health in good condition. Although GKI can be useful for anyone monitoring their glucose/ketone levels for therapeutic or dietary purposes, it is especially important for those struggling with chronic health conditions like diabetes, Alzheimer’s disease, Parkinson’s disease, and insulin resistance.

In the study “Therapeutic benefit of combining calorie-restricted ketogenic diet and glutamine targeting in late-stage experimental glioblastoma”, researchers found that low GKI values were correlated to a decrease in tumor size (Mukherjee et al., 2019).

As mentioned above, GKI can be helpful for those looking to achieve weight loss and therapeutic wellness. GKI helps with monitoring their current progress by keeping track of both glucose and ketone levels.

  • GKI > 9: You have not reached ketosis.
  • GKI 6-9: You are at a low level of ketosis that is ideal for weight/fat loss and overall wellness.
  • GKI 3-6: You are at a moderate level of ketosis that is ideal for those diabetes, obesity, metabolic syndrome, insulin resistance, etc.
  • GKI < 3: This is a therapeutic ketosis level that is ideal for those who with chronic health conditions like cancer, Alzheimer’s disease, or Parkinson’s disease.

To measure your GKI, you can download our SmartLog mobile app, which can be connected to our KetoSens Bluetooth meter and CareSens N Plus Bluetooth meter via Bluetooth connectivity! Manual entry is also available for non-Bluetooth meters!
