Good morning! I work for a Bariatric Surgeon with over 25 years experience of successful weight loss surgeries and I sent him your question. Ara Keshishian, MD wants to provide you guys with more resources to learn about your procedures and lifestyle post-procedure. Here is his reply:
“I do not recommend this, since there is no scientific evidence that placing the patient on a liquid diet for any period of time, does anything to distorted anatomy after the band. In general Protein shakes are good food replacement- substitute, as long as the carb to protein ration is better than 1:3 (a Protein shake with 5 g CHO:20g protein is better than 10 g of CHO with 40grams of protein)” If you have any other questions you'd like answered, please let me know and I'll send them to him!
