About this study

Standard dietary regiments for bariatric are advised prior to surgery. The most used diet is a very low calorie diet (VLCD). These diets potentially have multiple pittfalls. Very low-calorie ketogenic diets (VLCKD) have been proposed as a new regimen for achieving weight- and liver volume loss in patients undergoing bariatric surgery. The beneficial effect of VLCKDs compared to (V)LCDs is the aimed preservation of FFM and RMR, while still reducing FM. Only a few small studies addressed the role of VLCKDs prior to bariatric surgery, and the data including FFM and FM is actually scarce. Therefore, a well-designed randomised controlled trial is necessary to establish the efficacy of a VLCKD.
