Low-calorie Diet and Body Composition Prior to Roux-en-Y Gastric Bypass — LCD  

Morbid Obesity Clinical Trial

Official title:
The Effect of a 2-week vs. 6-week Low-calorie Diet (LCD) Followed by Roux-en-Y Gastric Bypass (RYGB) on Body Composition and Surgery Outcomes in Obese Humans: a Dietary Intervention and Magnetic Resonance Imaging Study

Clinical Trial Summary

Losing weight before undergoing Roux-en-Y gastric bypass (RYGB) surgery may reduce liver fat content and size thereby improving surgical outcomes. This study aims to investigate whether a 2-week or 6-week pre-operative liquid formula low-calorie diet (LCD) reduces liver fat further than a conventional food diet prior to RYGB using magnetic resonance imaging (MRI). The hypothesis is that the 2-week and 6-week liquid formula LCD will reduce liver fat further than the conventional food pre-operative diet.

Clinical Trial Description

The morbidly obese subjects (BMI higher then 40 kg/m2) were randomised and assessed at baseline (week 0). After 2 weeks on a low-calorie diet (LCD), participants underwent either Roux-en-Y gastric bypass (RYGB) or continued with a LCD for 4 weeks.The participants will reassess at week 6. ;
