Medical Body Composition Analysis (BIA)

Body weight alone tells very little about the actual changes during weight loss. A person can lose 5 kg of fat mass while simultaneously gaining 2 kg of muscle mass — the weight only drops by 3 kg, even though the success is much greater. Bioelectrical Impedance Analysis (BIA) precisely distinguishes between body fat, skeletal muscle, body water, and visceral fat.

What BIA Measurement Assesses

We use the seca mBCA Ultra, a medical bioimpedance analyzer with 8-point measurement technology. It assesses:

• Body Fat Percentage: Precise determination of the percentage of fat mass relative to total body weight.
• Skeletal Muscle Mass: Assessment of lean body mass (musculature), an important indicator for strength, metabolism, and quality of life.
• Body Water: Quantification of water balance, relevant in edema or metabolic disorders.
• Visceral Fat: Measurement of abdominal fat — the independent risk factor for cardiovascular disease, diabetes, and inflammation, independent of BMI.^[2]

When is BIA Measurement Useful?

• Obesity Therapy: For baseline assessment and regular follow-up monitoring to objectively evaluate success (fat mass reduction vs. muscle preservation).
• GLP-1 Receptor Agonist Therapy: Documentation of body composition during pharmacological treatment.
• Diabetes and Metabolic Therapy: In type 2 diabetes and metabolic syndrome to assess visceral fat deposition.
• Sports Medicine Questions: In trained individuals to distinguish between muscle and fat mass (e.g., weight gain from muscle building).
