A 4-Week Preoperative Ketogenic Micronutrient-Enriched Diet Is Effective in Reducing Body Weight, Left Hepatic Lobe Volume, and Micronutrient Deficiencies in Patients Undergoing Bariatric Surgery: a Prospective Pilot Study.

This study demonstrates that a 4-week preoperative KMED is safe and effective in reducing BW, left hepatic lobe volume, and correcting MD in obese patients scheduled for BS. Decreases in BW, left hepatic lobe volume, and an amelioration of patient micronutrient status were all highly significantly. All patients showed a high frequency of acceptability and compliance in following the diet. No adverse side effects were reported.
