• Signals risk for nonalcoholic fatty liver disease through a validated surrogate.
• Tracks response to nutrition, activity, sleep, and weight-loss interventions over time.
• Integrates triglycerides, fasting glucose, and BMI into one clear risk score.
• Identifies hidden risk in people with normal BMI but unfavorable triglyceride–glucose status.
• Supports personalized tracking for both males and females across life stages.
• Compares well with HOMA-IR in research as a practical insulin resistance marker.
• Simple, accessible, and cost-effective using routine laboratory measures.

What is TyG-BMI Index?

TyG-BMI is a composite index that reflects insulin resistance and metabolic stress. It merges the Triglyceride–Glucose (TyG) index with Body Mass Index to sharpen risk detection. The TyG component uses fasting values: TyG = ln [triglycerides (mg/dL) × fasting glucose (mg/dL) / 2]. TyG-BMI multiplies that TyG value by BMI to account for adiposity. Higher values indicate a higher probability of insulin resistance and a heavier cardiometabolic load.

Across diverse populations, researchers link TyG-BMI with prediabetes, type 2 diabetes, metabolic syndrome, nonalcoholic fatty liver disease, and cardiovascular risk. The result is a single, easy-to-track number derived from routine blood work plus measured height and weight. TyG-BMI can be calculated from fasting triglycerides, fasting glucose, and BMI, then viewed in context to understand what drives the score and how it can change over time.

Why is TyG-BMI Index Biomarker Testing Important?

Insulin resistance sits at the center of metabolic health. TyG-BMI captures insulin resistance risk by combining lipid handling, glucose control, and body size into one metric. This index offers early warning for dysglycemia and vascular stress, often before fasting glucose alone signals trouble. Higher TyG-BMI is associated with greater odds of prediabetes, type 2 diabetes, fatty liver, hypertension, and atherosclerotic disease. The index also distinguishes risk among people with the same BMI, revealing those with unfavorable triglyceride–glucose physiology.

TyG-BMI supports monitoring during lifestyle changes, weight management, or medical therapy because it moves with real-world habits and metabolic shifts. Establish a baseline and track a trendline to see progress. You gain a practical, research-backed surrogate for insulin resistance that fits into everyday life.

What Insights Will I Get?

• Optimal (lower TyG-BMI):
  • Males: Strong insulin sensitivity, lower visceral fat burden, favorable cardiometabolic profile.
  • Females: Strong insulin sensitivity, lower ectopic fat risk, favorable reproductive–metabolic balance.
• Elevated (moderately high TyG-BMI):
  • Males: Early insulin resistance signals, rising visceral adiposity, higher metabolic syndrome likelihood.
  • Females: Early insulin resistance signals, central adiposity shift, higher fatty liver and cycle-related metabolic strain likelihood.
• High (markedly high TyG-BMI):
  • Males: High insulin resistance probability, strong links with prediabetes/diabetes and cardiovascular risk.
  • Females: High insulin resistance probability, strong links with prediabetes/diabetes, fatty liver, and hormone–metabolic disruption.
• Trend insight:
  • Downward movement over time reflects improving insulin sensitivity and cardiometabolic risk reduction.
  • Upward movement signals worsening risk that needs focused action.

TyG-BMI Index and Your Health

Your TyG-BMI highlights the levers that matter. Nutrition strategies that emphasize fiber-rich, minimally processed foods, smart carbohydrates, and balanced fats help normalize triglycerides and fasting glucose. Physical activity that includes resistance training and regular aerobic work improves insulin signaling and reduces visceral fat. Consistent sleep and stress regulation stabilize glucose and lipid dynamics. Weight management shifts BMI downward and lowers the index through fat loss, especially centrally. Alcohol moderation supports triglyceride control and liver protection.

Medication strategies, when used, can be aligned with your index and comorbidities. Set clear next steps and retesting timelines to see how daily choices move the number. You gain clarity, direction, and measurable feedback on your path to stronger metabolic, heart, and liver health.
