Background: Gastric surgery-induced body fat loss automatically reduces fat-free mass (FFM) by changing the fat-free component of adipose tissue. A recent study first reported a change in fat fraction percentage of adipose tissue during gastric bypass surgery-induced weight loss, using chemical shift-based water/fat separation method. Results and Conclusion: Our proposed models showed that dual-energy X-ray absorptiometry-derived FFM was affected by changing the fat-free component of adipose tissue during gastric surgery weight loss, the magnitude of which depends on the proportion of fat-free adipose tissue used in the model.
