Brief Summary: The goal of this observational study is to evaluate whether preoperative fat-free mass predicts post-operative weight loss in patients undergoing Roux-En-Y gastric bypass.
The primary objective of this study is to evaluate whether preoperative fat-free mass predicts weight loss in the two years following RYGB.
We will collect the following data, assessed as part of routine follow-up:
* height, weight, hip and waist circumferences
* body composition by bioimpedance analysis and dual energy-X-ray absorptiometry
* Muscle stre...
