Brief Summary

Candidates to bariatric surgery at The Bariatric and Metabolic Institute at Cleveland Clinic Florida are prescribed a high protein liquid diet for two weeks preoperatively and 2 weeks postoperatively. Whether Wolffia Globosa (Mankai), a plant based wholesome food, can serve as a natural alternative to liquid diet during the 2 week pre-operation and 2 weeks postoperation liquid based diet, is unknown. The investigators aim to address the effect of daily Wolffia Globosa (Mankai) administration on morbid/severely-obese patients during the 2 week pre-operative period and 2 weeks postoperatively as compared to iso protein-iso caloric shake source on the following parameters

Study Arms (2)

Mankai Group

EXPERIMENTAL

The pre-operative liquid diet will be started two weeks before surgery date for both groups. During the first week patients in group A (Wolffia Globosa) will be allowed to have two meals a day and one protein shake (Wolffia Globosa) of 16 oz. Each meal will consist of 3-5 oz of lean protein (Chicken, turkey or fish) and one cup of vegetables or salad. During the second week, patients will drink one protein shake of 16 oz (Wolffia Globosa) as a meal replacement, three times per day and will not be allowed to eat solid food. Patients will also be allowed to Drink clear liquids in between protein shakes.

Other: Dietary modification with introduction of Mankai

Control Group

NO INTERVENTION

The pre-operative liquid diet will be started two weeks before surgery date for both groups. During the first week patients in group B (Control) will be allowed to have two meals a day and one protein shake (Control) of 16 oz. Each meal will consist of 3-5 oz of lean protein (Chicken, turkey or fish) and one cup of vegetables or salad. During the second week, patients will drink one protein shake of 16 oz (Control) as a meal replacement, three times per day and will not be allowed to eat solid food. Patients will also be allowed to Drink clear liquids in between protein shakes.

Interventions

Substituting the standard high protein, low carbohydrate preoperative shake during the preoperative liquid diet with Wolffia Globosa (Mankai) shake consisting of 16 oz of skim milk + 1 frozen cube of Wolffia Globosa (Mankai) +/- sugar substitute.
