Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of the study is to evaluate the effect of nutrition intervention on gastrointestinal symptoms, treatment discontinuation rate, nutritional parameters (e.g., dietary intake and eating habits), anthropometric measures, functional parameters, and QOL during the initiation and up-titration phase of incretin-based Anti Obesity Medications (AOM) treatment in patients with overweight/obesity.

The nutrition intervention protocol will be developed based on literature review, focus groups with health care professionals, and patient interviews.

A single-center pilot study will be performed at the Tel-Aviv Assuta Medical Center, among 10 patients who are about to initiate long-term weight management treatment with Wegovy© (semaglutide 2.4 mg), followed by a multi-center, parallel design open-label, RCT, which will be conducted at the Tel-Aviv Assuta Medical Center and Rabin Medical Center - Beilinson Hospital, in 120 patients who are about to initiate long-term weight management treatment with Wegovy© or Mounjaro© .

The intervention group will receive nutrition guidance before AOM treatment by registered dietitian (RD) followed by nutrition and behavioral recommendations according to reported gastrointestinal symptom(s). The control group will receive the usual nutrition care for patients treated with AOM.

Primary outcomes (gastrointestinal symptom assessment) and secondary outcomes (incretin-based AOM discontinuation rate, nutritional parameters, anthropometrics, functional parameters and QOL) will be evaluated by interviews, questionnaires and measurements at baseline, at the end of Wegovy© or Mounjaro© titration phase \[20 weeks (T1)\] and weekly during the study period (for GI symptoms assessment).

Study Groups

Nutritional intervention group

Nutrition guidance before AOM treatment by registered dietitian (RD) followed by nutrition and behavioral recommendations according to reported gastrointestinal symptom(s).

Group Type EXPERIMENTAL

nutritional intervention

Intervention Type BEHAVIORAL

A nutrition guidance before initiation of AOM treatment include recommendations for food choices and eating habits to minimize the occurrence and severity of GI symptoms during the up-titration phase, will be given by registered dietitian (RD) from the study team. Next, each week, participants will provide weekly reports of GI symptoms occurrence and severity, by responding to queries sent via WhatsApp/SMS and for occurring symptoms, an automatically structured nutrition and behavioral treatment recommendations will be sent . If participants expressed an interest in personalized dietary guidance on this matter, the study team RD will contact him/her by telephone, within a range of 48 hours, to provide individualized recommendations. Three days after each report of GI symptom(s), participants will receive an additional message and will be asked to report the occurrence and severity of the GI symptom, and their compliance with the specific dietary instructions received.

Control group

* Usual nutrition care treatment for patients treated with Wegovy© or Mounjaro© (RCT).
* Prior to the initiation of AOM treatment, participant will receive general nutrition guidance based on national recommendations according to the Mediterranean diet.
