Primary Outcome Measures

Name	Time	Method
<p>The main study parameter is the percentage fat free mass loss six months after<br /><br>surgery, calculated as fat free mass loss (kg) divided by total fat free mass<br /><br>(kg) before surgery. Fat free mass will be assessed by multi-frequency<br /><br>bioelectrical impedance analysis (MF-BIA). </p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Secondary parameters are total weight loss, BMI before and after surgery, fat<br /><br>mass, hand grip strength, physical activity and total protein intake. </p><br>
