The Glucose Ketone Index (GKI) is a numerical indicator that compares your blood glucose levels to your blood ketone levels. It provides insight into your current metabolic state — especially useful if you're aiming to enter or maintain ketosis. A lower GKI suggests deeper levels of ketosis, which may be helpful in certain therapeutic contexts, such as type 2 diabetes, neurological disorders, or cancer support protocols. Many people also track GKI during ketogenic diets to optimise fat-burning and metabolic health.
