Assessment of adipose tissue and lean body mass (LBM) is useful in clinics to follow‐up obese patients on diet and cases of body weight (BW) loss (e.g. malnutrition) or gain of muscle mass due to physical training or experimental special diets or products. The present study was conducted on 76 well‐selected healthy Caucasian women aged 22.0 ± 1.9 yrs. BW and body fat distribution were normal based on BMI and Waist/Hip ratio. Body frame was medium based on ∑acromial‐bitronchanteric distances. Circumferences and skinfolds were measured at several Lohman sites; muscular circumferences and surfaces were calculated by means of validated equations. % adipose tissue values obtained from Tanita and the practical Gallagher et al.’s equation based on BMI were similar to the Durnin & Womersly’s reference equation; Omron over‐estimated by 22.8% (( p <0.0001). The Tanita scale is misleading for LBM; the value 76.9 ± 7.7% of BW corresponds to total fat‐free body (FFB), a body compartment of no great clinical interest. Values from Lee et al.’s equation and the Omron scale reflected LBM. Compared with the value derived from Heymsfield et al.’s reference equation for muscular tissue, the difference was significant ( p <0.001) in the former case; the % ∆ of Omron was only ‐0.5. In conclusion, the two BEI scales are not equal in determining BC, Tanita and Omron being reliable only for adipose or muscular tissues, respectively.
