DEXA Scan (Body Composition & Bone Density)

Dual-energy X-ray absorptiometry (DEXA) scanning at Proactive Longevity's Beverly Hills clinic, assessing bone mineral density, lean muscle mass, and visceral fat distribution. A key diagnostic tool in the PEAK longevity program's Discovery phase, enabling precise body composition tracking as a biomarker of biological aging and metabolic health. Physician-interpreted results used to personalize nutrition, supplementation, and fitness protocols. Pricing on consultation.

Proactive Longevity's DEXA scan service provides a highly precise, low-radiation body composition assessment that goes far beyond standard scale-based weight or BMI measurements. DEXA — dual-energy X-ray absorptiometry — uses two X-ray beams at different energy levels to differentiate between bone mineral, lean soft tissue (muscle), and fat tissue throughout the body. This produces a full-body map of compartmental body composition with regional precision: total and regional lean muscle mass (arms, legs, trunk, and android/gynoid fat zones), total body fat percentage and absolute fat mass, visceral adipose tissue (VAT) — the metabolically active fat stored around internal organs that is strongly associated with cardiovascular disease, insulin resistance, and inflammatory aging — and bone mineral density (BMD) with T-score and Z-score calculations for fracture risk assessment. From a longevity medicine perspective, DEXA provides actionable data on two of the most important modifiable aging biomarkers: skeletal muscle mass (lower muscle mass, particularly sarcopenia, is associated with mortality and functional decline in aging) and visceral fat (a primary driver of metabolic syndrome, chronic inflammation, and cardiometabolic disease). Serial DEXA measurements, conducted at intervals during the PEAK program's Optimization and Evolution phases, allow the clinical team to objectively track the impact of dietary, exercise, hormone, and supplementation interventions on body composition over time — providing a quantitative feedback loop that qualitative assessments cannot replicate. The scan itself takes approximately 15–20 minutes and uses radiation doses far below typical diagnostic X-ray levels. Results are reviewed with patients by Proactive Longevity's physician team at the Beverly Hills clinic, with interpretation in the context of the individual's full biomarker profile and longevity objectives.
