Comparing body composition techniques against an adapted multicompartment model in individuals with excess body weight
Overall, ADP demonstrated the best accuracy, while DXA had the greatest differences compared to the 4C model. This may have resulted from TBW being overestimated by BIA, which would inflate 4C-derived fat-free mass. Although all methods demonstrated strong agreement for group-level BF%, a substantial individual-level variability (up to 5% error) highlights the need for caution when interpreting results in clinical or personalized assessment contexts in individuals with excess body weight.
