Nutritional Management and Role of Multidisciplinary Follow-Up after Endoscopic Bariatric Treatment for Obesity
Round 1
Reviewer 1 Report
The manuscript by Negi A, et al., titled as "Nutritional Management and Role of Multidisciplinary Follow- up After Endoscopic Bariatric Treatment for Obesity" is a review article, authors have reviewed methods involved in bariatric treatment, post-treatment followup methods and nutritional interventions.
Here are my comments to authors:
1. The manuscript not meeting the satisfying level of level of "title" "Nutritional Management and Role of Multidisciplinary Follow- up" it is lacking information on nutritional management.
2. Explain in detail what is mean by MDT followup, accountability? and how a patient can follow up?
3. authors have mentioned (line 190) negative energy balance, write more on it, and give details/recent literature about diet/food to achieve it.
4. Fig. 4 is good, but missing a good placement. try to write more on it and put it before conclusion.
5. I have missed the supplementary data, I couldn't find it in this manuscript.
please provide supplementary files.

Dear Editor and Reviewers,
Thank you very much for the reviews and comments. We have amended the manuscript as suggested.
Reviewer 1
1) The manuscript not meeting the satisfying level of level of "title" "Nutritional Management and Role of Multidisciplinary Follow- up" it is lacking information on nutritional management.
We have amended the manuscript and added more information on nutrition.
“General Nutritional Principles
Pre-EBT evaluation
In our practice, we conduct a baseline nutritional assessment similar to the ASMBS nutritional guidelines [11, 20]. We perform anthropometric measurements and obtain weight histories such as failed weight loss attempts, current co-morbidities, food allergies, eating disorders, current/past psychiatric diagnosis, alcohol/tobacco use, dietary intake, physical activity level, and psychosocial factors such as motivation level, readiness to change, stress and coping mechanism. This information is crucial for adaptation to eating habits after the procedure and addresses individual barriers to weight loss success.
Micronutrient deficiencies are frequently encountered among patients with obesity due to overconsumption of low nutrient, high-calorie foods that lack nutrient densities before EBT [20]. Deficiency in iron, B- vitamins, vitamin D, and folate has been reported. Malabsorptive procedure like Roux -en -Y gastric bypass is known to exacerbate micronutrient depletion of vitamin B12 and other B vitamin complex, iron and calcium. Restrictive procedures, such as EBT, do not induce malabsorption. However, poor food choices, food intolerance and restricted portion size can contribute to micronutrient deficiency Recognition and correcting the micronutrient deficiencies before is considered optimal to prevent post-EBT deficiency. We prescribe a multivitamin-mineral supplement to meet the daily requirements.”
“Attaining a negative energy balance (~300-500Kcal) is crucial for sustained weight loss. We emphasize more on the quality of diet than the quantity. The DIETFITS randomized clinical trial did not show a significant decrease in weight loss between low fat and low carbohydrate diets at 12 months [30]. However, the quality of the diet- low intake of processed foods and added sugars, high intake of fruit, vegetables, and whole-grain products determined the weight loss in obese patients. As per the carbohydrate-insulin model of obesity, carbohydrates elevate insulin secretion leading to fat storage in adipose tissue, therefore we advise our patients to limit processed foods, carbonated beverages, fruit juices and added sugars to less than 10% of daily calorie intake [31].”
“Dietary Planning
Generally, it is challenging to lose weight without achieving a negative energy balance, which is determined by energy intake and expenditure. The energy balance is regulated by a complex interaction of endocrine, metabolic, and nervous system signals to control food intake in response to the body's dynamic energy needs and environmental influences [31]. We expend energy through resting metabolic rate- the energy required for the body's functioning at rest; physical activity; and thermogenic effect of food- the energy needed for digestion, absorption, and storage of nutrients in the food. Change in body weight occurs when energy expenditure is higher than intake over a given period of time, resulting in loss of body fat mass. When designing a dietary intervention, an individualized diet that achieves a state of negative energy balance should be prescribed. Several dietary approaches are available based on the inclusion and restriction of different food components to achieve and maintain weight loss (Figure-4). These include modification of macronutrients formulation of the food (low carbohydrate diet; low-fat diet; high protein diet); inclusion of diverse food groups (Mediterranean diet- based on rich plant-based food and moderation of refined grains, red meat, and dairy); restriction of specific foods (Paleo diet, Vegan diet, Gluten-free diet) and time restricted eating [33]. A recent network meta-analysis of randomized trials on 14 popular macronutrient diets showed that most diets resulted in modest weight loss and improved blood pressure over six months [34]. At 12 months, weight reduction diminished, and blood pressure improvements largely disappeared. Likewise, a randomized study comparing time restricting eating to a daily low calorie diet showed no difference in reduction in body weight, body fat, or metabolic risk factors in patients with obesity [35]. Thus, to promote long-term adherence, any dietary intervention should take into consideration the patients' food preferences, cultural background, and food availability.
There is scarcity of literature surrounding type of meal planning for long term after EBTs. The limited evidence focuses on use of either Mediterranean diet or high protein diet [36]. The Mediterranean diet (carbohydrates-53%, proteins-22%, and fats-25%) is characterized by an abundance of plant-based foods, a moderate intake of fish and dairy, a low intake of red meat, and the use of extra virgin olive oil as the main source of dietary fat. The anti-inflammatory and anti-oxidant property of the Mediterranean diet has been postulated to promote weight loss and improvement on comorbidities. Short term studies (3 months) have demonstrated superiority of Mediterranean diet over high protein diet in inducing weight loss in obesity. However, long term studies in EBT are lacking.
The high protein diet is the frequently subscribed diet post-EBTs. The protein-based bariatric plate model by Cambi et al. describes the macronutrient and micronutrient composition of daily meals to promote and maintain weight loss over the long term after EBT (Figure-5). The model recommends 50% calcium and iron-rich protein, 30% vitamins, minerals, and fibers, represented by fruits and vegetables, and 20% whole carbohydrates with a low glycemic index [37]. Lipids in the form of Canola or olive oil were suggested. The high protein and fibre rich diet are thought to be associated with improved satiation, satiety, and reduced food intake. In our practice, we use a combination of Mediterranean and high protein diets to promote weight loss based on patient preference.”
2) Explain in detail what is mean by MDT followup, accountability? and how a patient can follow up?
We have added the following to the manuscript “Obesity is a multi-faceted problem, and health care delivery must adhere to the core principles of the chronic care model, which emphasizes long-term commitment, patient-centered intervention, using evidence-based protocol-driven care, and delivery of treatment within a multidisciplinary team [39]. Having a multidisciplinary unit comprising gastroenterologists, bariatric surgeons, obesity medicine physicians, nutritionists, physiotherapists, pharmacists, and case managers, would facilitate addressing patients' unique care and concerns, and personalize the treatment (Table-2).”
“There is no “one-size-fits-all approach to treating obesity. We believe introducing new, appealing, patient-centered interventions, involving family members, and appreciating the benefits they have already achieved may promote long-term adherence to weight maintenance efforts.” We have included a Table on the components of a multidisciplinary team.
3) authors have mentioned (line 190) negative energy balance, write more on it, and give details/recent literature about diet/food to achieve it.
We added to the manuscript “Generally, it is challenging to lose weight without achieving a negative energy balance, which is determined by energy intake and expenditure.

4) Fig. 4 is good, but missing a good placement. try to write more on it and put it before conclusion.
As suggested, we have expanded more on it and added before conclusion
