What is a good GKI for weight loss?

For weight loss and general health, a GKI between 3.0 and 6.0 is considered the 'sweet spot.' It indicates moderate ketosis where your body is efficiently burning fat for fuel.

How often should I test my GKI?

Most people find testing once a day, usually in the morning while fasted, provides the most consistent baseline. Testing after meals or exercise can cause temporary spikes that don't reflect your overall metabolic state.

Is a GKI below 1.0 dangerous?

A GKI below 1.0 is generally only sought for therapeutic purposes (like cancer or epilepsy treatment) under medical supervision. For the average healthy person, it's not necessary and can be difficult to maintain.

GKI Calculator

The Glucose-Ketone Index (GKI) gives you a single number to track your metabolic health and ketosis depth.

Your GKI Score

0.0

< 1.0: Highest Therapeutic Ketosis (Treating diseases)
1.0 - 3.0: High Therapeutic Ketosis (Deep fat burning)
3.0 - 6.0: Moderate Ketosis (Functional weight loss)
6.0 - 9.0: Low Ketosis (Maintenance)
> 9.0: No Ketosis

How This GKI Tool Works

The Glucose-Ketone Index (GKI) is a sophisticated formula that tracks the clinical depth of your ketosis. While testing ketones alone is useful, your blood sugar levels also play a massive role in metabolic health. This tool integrates both metrics into a single score that remains stable regardless of minor daily fluctuations.

How to Read Your GKI Score

1.0 - 3.0: Deep Ketosis. High therapeutic benefit for metabolic diseases.
3.0 - 6.0: Moderate Ketosis. The optimal zone for consistent weight loss and mitochondrial health.
6.0 - 9.0: Low Ketosis. Generally the 'maintenance' zone for high-performance athletes.

Example: Morning Fasted Reading

You wake up and test your blood:

- Glucose: 85 mg/dL
- Ketones: 1.8 mmol/L
- GKI Score: 2.62 (Highest Therapeutic Zone)

This result shows that even if your glucose is slightly high, your high ketone level is over-compensating, keeping you in a deep fat-burning state.

Biohacker Tip: If your GKI is higher than 9.0 even with low carbs, check your stress levels and sleep. High cortisol can drive blood sugar up, even if you aren't eating sugar, effectively kicking you out of ketosis.

GKI Intelligence FAQ

Why divide by 18?

The '18' is the conversion factor used to change glucose from mg/dL (US standard) to mmol/L (International standard). This allows for a clean 1:1 ratio with ketones, which are always measured in mmol/L.

Can I use urine strips?

No. GKI requires precision blood testing. Urine strips measure acetoacetate (excess waste), while GKI requires Beta-hydroxybutyrate (circulating fuel) and glucose readings.

What is 'Therapeutic' Ketosis?

Therapeutic ketosis (GKI < 3) is used by doctors to treat neurological disorders and metabolic dysfunction. It suppresses inflammation and provides a more 'stable' fuel source for the brain than glucose.
