TG/HDL Ratio Calculator
Metabolic Relevance
TG/HDL ratio reflects the balance between triglycerides and "good" cholesterol. A high ratio indicates small, dense LDL particles and insulin resistance — even when total cholesterol is normal.
Recommended testing frequency:
Every 3-6 months when monitoring lifestyle changes, annually once stable
Did you know?
The McLaughlin study (2003) found that TG/HDL ratio ≥3.0 identifies insulin resistance with 79% accuracy — even when traditional cholesterol numbers look "normal".
TG/HDL ratio can improve quickly with carbohydrate reduction and regular exercise — often within 2-4 weeks of dietary changes.
