Safety and Effectiveness of a 4-Week Diet on Low-Carb Ready-to-Eat Products as Preoperative Care Treatment in Patients Scheduled for Metabolic and Bariatric Surgery

We observed highly significant decreases in BW (-6.5%, p < 0.001), and LLLS volume (-22.3%, p < 0.001) and an amelioration of patient clinical status. All patients showed a high frequency of acceptability and compliance in following the diet. No adverse side effects were reported. Based on our findings, we were able to support the hypothesis that a 4-week preoperative RLCKP diet is safe and effective in reducing BW, and LLLS volume in patients with obesity scheduled for MBS.
