The metabolically-active abdominal fat linked to cardiovascular + insulin-resistance risk. Hard to see; visible in labs.
Visceral adipose tissue (VAT) is the fat stored around the organs inside the abdominal cavity — distinct from subcutaneous fat (under the skin). It's metabolically active and drives systemic inflammation, insulin resistance, and cardiovascular risk. Unlike total body fat, visceral fat can be high even in people who look relatively lean.
Direct measurement options include DEXA scan (body composition) and abdominal MRI. Proxy measures include waist circumference (>40" men / >35" women suggests elevation) and waist-to-hip ratio. Lab markers don't measure VAT directly but reflect its metabolic consequences.
Tesamorelin has FDA approval specifically for visceral fat reduction in HIV-associated lipodystrophy and is used off-label by many under clinician supervision for broader visceral-fat work. Lifestyle levers (caloric deficit, resistance training, sleep, stress management) are foundational.
The following lab markers are commonly discussed with a licensed provider in this context. They are not a diagnostic checklist. Only your clinician can interpret what these values mean for your specific situation.
MyProtocolStack lets you log the biomarkers on this page across lab draws, chart the trend, and hand a structured report to your clinician. Better conversations start with better data. We do not replace your provider; we help you show up prepared.
