Evidence-based evaluation by medical professionals
"A feature-rich smart scale that pairs solid accuracy with uniquely deep cardiovascular insights, though its extras add cost some users may not need."
Across a six-week prospective study, 40 adult participants (BMI 19-34 kg/m²) used the Withings Body Comp alongside a Class III calibrated beam scale and dual-energy X-ray absorptiometry (DEXA). Weight error averaged 0.08 kg (±0.11), while body-fat and muscle-mass errors averaged 7.4 % (±2.1), which is higher than thresholds considered acceptable for research or professional athletes. Even so, the scale’s multi-frequency bioimpedance still captures directional changes that suit everyday trend tracking, and its vascular-age and electrodermal-activity (EDA) outputs correlated moderately (r = 0.46-0.52) with carotid-femoral pulse-wave-velocity and Sudoscan reference devices. No device-related adverse events occurred, and overall Body Comp supplies convenient core metrics plus novel cardiovascular and nerve-health indicators, albeit at a premium price compared with basic smart scales.
