I would like to congratulate the authors of this manuscript on a well-executed and important study. With the dramatic increase in the prevalence of surgical treatment for morbid obesity, it has become essential for clinicians to better select and preoperatively prepare patients to decrease the postoperative procedure-related morbidity and mortality as well as to achieve excellent long-term results. Currently, there are no clear guidelines from the leading bariatric societies as to whether morbidly obese patients should undergo a preoperatively supervised diet to achieve postoperative weight loss and better outcomes.
