Body Composition Analysis

What is Bioimpedance Analysis (BIA)?

Bioimpedance analysis uses frequencies to measure fluid in the body.

What is VLA50?

VLA50 is a device which measures impedance at 50kHz. VLA50 software then calculates body water and body composition using equations based on underwater weighing and DXA. BIA has shown a strong correlation with DXA.


Information Provided by VLA50

  • Body Fat Mass (kg/%)
  • Active Lean Mass (kg/%)
  • Total Body Water (Hydration)
  • Extracellular Water
  • Intracellular Water
  • Cellular Function and Health
  • Biological age

BIA enables me to assess your health and ensure weight reduction is extracellular water and body fat. As a result I can assist you to achieve the optimal body composition.
