WHY TEST GLUCOSE & KETONES TOGETHER
Ketones tell part of the story. Glucose tells another. The GKI (Glucose Ketone Index) tells the whole story - and it's the number that matters most for understanding metabolic health.
WHAT IS GKI?
The Glucose Ketone Index is a single number that shows the relationship between glucose and ketone levels. It's calculated by dividing glucose by ketones - and the result reveals how deep into ketosis the body actually is. Ketone levels alone can be misleading. Someone with high ketones but high glucose isn't in the same metabolic state as someone with high ketones and low glucose. GKI captures what neither number shows on its own.
WHY GKI MATTERS:
More accurate than ketones alone. A true measure of metabolic state. Used by researchers, doctors, and serious keto practitioners. The difference between "I think I'm in ketosis" and "I know exactly where I stand."
GKI RANGES:
Above 9: Not in ketosis
6 - 9: Low level ketosis
3 - 6: Moderate ketosis (typical target for weight loss and metabolic health)
Below 3: Deep ketosis (therapeutic range, often used for specific health protocols)
The lower the GKI, the deeper the state of ketosis.
HOW TO CALCULATE GKI:
Divide your glucose reading (in mmol/L) by your ketone reading. If your meter displays glucose in mg/dL, divide by 18 first to convert. Example: Glucose of 90 mg/dL (5.0 mmol/L) with ketones of 1.5 mmol/L = GKI of 3.3
WHY YOU NEED BOTH:
Ketone Testing Shows:
Whether the body is burning fat for fuel. How different foods affect ketosis. Depth of fat-burning during fasting. Real-time confirmation that keto is working.
Glucose Testing Shows:
How food, stress, and activity affect blood sugar. Hidden carbs in "safe" foods. Individual response to specific meals. Data to help you and your doctor monitor diabetes control.
Together They Show:
True metabolic state via GKI. The complete picture of how the body is responding. Whether dietary changes are actually working. Precise data for optimizing health - not just guessing.
WHO TRACKS GKI:
Keto Dieters
GKI provides a more accurate measure of ketosis than ketones alone. It shows whether the diet is truly working and helps fine-tune food choices for better results.
People Monitoring Metabolic Health
Glucose and ketones are both key metabolic markers. Tracking them together provides a fuller picture to share with healthcare providers.
Extended Fasters
GKI tracks the depth of fasting states more accurately than ketones alone. Many fasters use GKI to monitor progress and determine when they've reached target levels.
Anyone Serious About Results
If testing matters enough to do it, it matters enough to do it right. Half the data gives half the picture. GKI shows what's really happening.
SAVE WHEN YOU BUY BOTH:
This bundle includes everything needed to test both glucose and ketones and track GKI. Buying together costs less than purchasing strips separately - and ensures you never run low on one while stocked up on the other.
THE BOTTOM LINE:
Your body is talking - start listening to the whole conversation. Ketones alone don't tell the full story. Glucose alone doesn't either. GKI brings them together into a single number that shows exactly where you stand.
