SECA Body Composition Analysis & Metabolic Assessment in Boston & Wellesley, MA

The SECA medical Body Composition Analyzer is a clinical-grade instrument validated for use in medical settings and capable of producing results with a significantly higher level of accuracy and reproducibility than consumer-grade body composition scales or gym-based impedance devices. It is widely used in clinical research and medical practice as a reliable tool for body composition assessment.

Body weight and BMI measure total mass and its relationship to height, respectively, without distinguishing between muscle, fat, bone, and water. SECA analysis provides a detailed, segmental breakdown of body composition—including muscle mass, fat mass, visceral fat, and cellular hydration—revealing the metabolically meaningful differences that weight and BMI cannot capture.

Visceral fat is the fat stored around the abdominal organs, as distinct from subcutaneous fat stored beneath the skin. It is metabolically active in ways that subcutaneous fat is not, producing inflammatory cytokines, contributing to insulin resistance, and significantly elevating the risk of cardiovascular disease, type 2 diabetes, and metabolic syndrome. SECA analysis quantifies visceral fat directly, providing a clinically actionable measure of metabolic risk that standard assessments do not capture.

Phase angle is a measurement derived from the bioelectrical impedance analysis that reflects the integrity of cell membranes and the ratio of intracellular to extracellular water. A higher phase angle generally indicates healthier, more intact cell membranes and better cellular hydration — and is associated with better nutritional status, lower inflammatory burden, and improved overall health. It is a meaningful indicator of cellular vitality that goes beyond standard body composition metrics.

The appropriate frequency depends on the goals being pursued and the interventions being monitored. For patients actively managing weight, body composition, or metabolic health, assessments every two to three months provide a meaningful picture of how body composition is changing in response to treatment. For patients in a stable maintenance phase, annual or biannual assessments are typically sufficient. Dr. Ahn will recommend a monitoring schedule based on your individual situation.

For the most accurate results, patients are asked to arrive well-hydrated, having avoided significant food intake, alcohol, and strenuous exercise in the hours before the assessment. Dr. Ahn will provide specific preparation instructions based on the timing of your appointment.

Yes. Serial SECA measurements are a particularly valuable tool for tracking the impact of body composition treatments such as Emsculpt, medical weight loss, and hormone optimization over time — providing objective, quantitative evidence of changes in muscle mass, fat mass, and visceral fat that complement clinical assessment and patient-reported outcomes.

Ahn Point Wellness is a cash-pay practice and does not accept insurance. Many patients find that HSA and FSA accounts can help offset the cost of care. Dr. Ahn will discuss the role of SECA analysis in your personalized health plan and associated costs during your consultation.
