DEXA Scan in San Francisco

Custom Fit SF uses a Hologic DEXA scanner to measure body fat percentage by region, lean muscle mass by limb, visceral adipose tissue (VAT), and bone mineral density — all in a 6-minute scan. Each session includes an immediate 15–20 minute results review with a Registered Dietitian or Exercise Physiologist who interprets your numbers in the context of your health and fitness goals. DEXA is widely considered the gold standard for body composition analysis, offering precision that standard scale weight or bioelectrical impedance cannot match.

DEXA SF uses dual-energy X-ray absorptiometry to measure body fat percentage, lean muscle mass, bone mineral density, and visceral fat with clinical-grade precision. Each 6-minute scan generates a full regional breakdown across the arms, legs, and trunk, and includes a consultation with a credentialed technician who interprets the results and links them to training and nutrition goals. The low-radiation exposure — roughly equivalent to half a day of natural background radiation — makes regular retesting practical for ongoing body composition tracking.
