DEXA SF

DEXA SF is a specialist body composition scanning studio located inside the Custom Fit gym at 323 Octavia Street in San Francisco's Hayes Valley neighbourhood. The clinic uses dual-energy X-ray absorptiometry — the same imaging modality used in clinical and research settings — to provide highly accurate measurements of body fat percentage, lean muscle mass, bone mineral density, visceral fat, and regional body composition across the arms, legs, and trunk. Every scan appointment includes a consultation with a credentialed technician, either a Registered Dietitian or Exercise Physiologist, who walks clients through their results and translates the data into actionable fitness and nutrition guidance. DEXA SF also offers resting metabolic rate testing, enabling clients to understand their caloric baseline and optimise energy intake. The clinic serves athletes, fitness enthusiasts, people pursuing weight management, and anyone seeking an evidence-based baseline for tracking body composition change over time. Its four-stage approach — Educate, Analyse, Train, Retest — emphasises repeated measurement and progress tracking rather than one-off testing.
