DEXA Technology Overview

Dual-Energy X-ray Absorptiometry (DEXA) provides the gold standard for body composition analysis, measuring fat, lean mass, and bone density.

Key Metrics Explained

  • Total Body Fat %: Overall fat percentage (healthy: men 10-20%, women 18-28%)

  • Visceral Adipose Tissue: Internal fat around organs (keep under 100cm²)

  • Lean Mass Index: Muscle mass relative to height (higher is generally better)

  • Bone Mineral Density: T-score above -1.0 is normal

Regional Analysis

DEXA shows fat distribution patterns:

  • Android (belly) vs Gynoid (hip) ratio

  • Arm and leg muscle symmetry

  • Trunk to limb fat ratios

Using Results for Goal Setting

  • Track changes every 3-6 months

  • Focus on trends rather than single measurements

  • Consider hydration status affects on results

  • Use data to adjust training and nutrition protocols
