Methoden

Navy-Methode: Hals-, Taillen- und Hüftumfang (Frauen). Genauigkeit ±3-4%. Caliper/Hautfaltenmssung: ±3%. Bioimpedanz (Waagen): ±4-5%. DEXA-Scan: ±1-2% (Goldstandard, 80-200 €). Smarte Waagen sind am ungenauesten — nur für Trendverfolgung nutzen.

Gesunde Bereiche

Männer: athletisch 6-13%, fit 14-17%, durchschnittlich 18-24%, über 25%+. Frauen: athletisch 14-20%, fit 21-24%, durchschnittlich 25-31%, über 32%+.

⚡ CalcWolf Insight

BMI classifies 30% of "normal weight" people as healthy when they actually have obesity-level body fat (called "skinny fat" or normal weight obesity). Body fat percentage is a far better indicator of metabolic health than BMI — two people with identical BMI can have dramatically different body fat levels.
