TyG-BMI (Triglyceride-Glucose-BMI Index)
TyG-BMI (Er 2016; TyG core Simental-Mendia 2008) = ln[(fasting triglycerides x fasting glucose) / 2] x BMI, lipids/glucose in mg/dL; a higher value marks greater insulin resistance (no universal cut-point).

Example
- Fasting triglycerides
- 150 mg/dL
- Fasting glucose
- 100 mg/dL
- BMI
- 25 kg/m^2
Result: TyG-BMI 223.07 — higher values indicate greater insulin resistance; interpretation is context-dependent (no universal cutoff).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- value
- TyG-BMI = ln[(TG x glucose)/2] x BMI, both mg/dL. Adds adiposity to the triglyceride-glucose index; higher is more insulin-resistant. No universal diagnostic cut-point.
