Know Your Body.
Optimize Your Health.

Your weight alone doesn’t tell the full story. Our advanced SECA Body Composition Analyzer provides a precise, science-backed picture of your health — with 97% accuracy compared to whole-body MRI for muscle mass and the gold-standard 4-Compartment Model for fat and fat-free mass.

Why It Matters

Medical-Grade Precision

97% accuracy compared to whole-body MRI for muscle mass measurement, providing clinical-grade insights into your body composition.
Most scales can’t distinguish between fat, muscle, or water. That’s why progress often feels confusing or misleading. The SECA scan goes deeper, giving you insights that help you:
  • Detect dangerous visceral fat not visible on the outside
  • Understand shifts in muscle vs. fat, not just weight changes
  • Optimize nutrition and training for real results
  • Track your body composition over time with medical precision
  • Build a personalized plan for healthy aging, fat loss, or muscle gain

What We Measure

The SECA scan captures more than 30 parameters of body composition in just minutes, including:

Body Composition

  • Total body fat percentage
  • Skeletal muscle mass
  • Fat-free mass

Segmental Analysis

  • Arms, legs, trunk analysis
  • Water distribution
  • Hydration levels

Metabolic Markers

  • Resting energy expenditure
  • Visceral fat index
  • Metabolic rate
