BODY FAT TEST Comparison: Hydrostatic, Skin Fold, DEXA Scan, BIA

Summary by Krater

The creator of Untamed Strength compares a digital body analyzer scale against hydrostatic weighing, a DEXA scan, skinfold calipers, and opinions from two bodybuilding coaches, concluding that the scale offers acceptable consistency for body fat tracking despite overestimating the absolute percentage.

Answers: How accurate is a digital body analyzer scale compared to hydrostatic weighing, DEXA, skinfolds, and professional coach estimates?

• body fat percentage testing methods
• digital body analyzer scale accuracy
• hydrostatic weighing
• DEXA scan
• skin-fold caliper body fat test
• lean body mass estimation

What it concludes

• The scale at Untamed Strength is unreliable because standing on it 5 separate times in 30 seconds gives 5 different readings.
• The digital body analyzer scale from Vantis Planet gave a body fat reading of 25.7%, which is higher than hydrostatic weighing at 17.8%, DEXA at 22%, and skinfolds at 18.6%.
• The digital body analyzer scale is consistent in body weight measurements, making a 3% decrease in body fat over a month valid regardless of absolute accuracy.
• Alberto Nuñez estimates body fat at 23% based on visual assessment of a 244 lb physique.
• Nsima Inyang estimates body fat between 18% and 22% based on visual assessment.
