Mindfulness-Based Nutrition Group Therapy as an Adjunct to GLP-1 Treatment of Obesity (MBNGT)

2026年6月10日 更新者：Leonie Bogl、Bern University of Applied Sciences

The goal of this clinical trial is to learn whether a mindfulness-based nutrition group program is feasible and acceptable for adults with obesity who are taking GLP-1 receptor agonist medication and receiving usual medical care, including dietetic counselling.

The main questions this study aims to answer are:

Can this group program be successfully carried out with adults receiving GLP-1 treatment? Do participants find the program useful, acceptable, and manageable? Are participants willing to attend the sessions, complete the home exercises, and fill in the study questionnaires?

Researchers will compare participants who receive the mindfulness-based nutrition group program plus usual care with participants who receive usual care only.

Participants in the group program will take part in a 16-week intervention with nine group sessions. They will practice mindful eating, mindfulness exercises, journaling, and peer exchange. All participants will complete questionnaires and body measurements at the start of the study, after 16 weeks, and 12 months after the start of the study.

The study does not test a new drug or device. The study team will not make decisions about participants' GLP-1 medication. All medication decisions remain part of usual medical care.

详细说明

This is a pilot, randomized, controlled, open-label, two-arm feasibility trial evaluating a mindfulness-based nutritional group therapy (MBNGT) as an adjunct to standard care in adults with obesity undergoing treatment with GLP-1 receptor agonists. The trial is designed to assess the feasibility of study procedures and the acceptability of the intervention, and to generate preliminary exploratory data to inform the design of a future adequately powered trial.

The MBNGT intervention is a 16-week dietetic group program integrating principles from mindfulness-based stress reduction, mindful eating approaches, nutritional therapy, and behavioral psychology. The intervention targets eating-related self-regulation, emotional awareness, mindful eating, and weight-related self-stigma. It includes structured group sessions, guided mindfulness and mindful eating exercises, journaling, home practice, and peer exchange. The intervention is delivered in addition to ongoing standard medical and dietetic care.

Participants randomized to the control group continue to receive standard care only. Standard care consists of routine medical management of obesity and dietetic counselling related to GLP-1 receptor agonist treatment. The study does not involve modification of pharmacological treatment, and decisions regarding continuation, dose adjustment, or discontinuation of GLP-1 receptor agonists remain under routine clinical care.

The primary focus of this pilot trial is feasibility, including recruitment, randomization, retention, intervention attendance, adherence to intervention components, completeness of data collection, and participant acceptability. Exploratory assessments will examine changes in eating behavior, mindful eating, internalized weight bias, self-regulation, emotional competence, mindfulness, psychological well-being, quality of life, body-related outcomes, and anthropometric and cardiovascular parameters. Semi-structured interviews will be used to explore participants' experiences with the intervention and perceived mechanisms of change.

Assessments are conducted at baseline, after the 16-week intervention period, and at 12 months after baseline. The results will be used to refine the intervention, assess participant burden, evaluate the suitability of outcome measures, and guide the selection of primary outcomes and procedures for a future larger randomized trial.

干预/治疗
无干预：Control group
The control group will receive usual care with standard dietetic counseling. At baseline, post-intervention and at 12 months follow-up, the same standardized questionnaires will be administered to assess changes in psychosocial, emotional, and behavioral variables (e.g., emotion regulation, self-stigma, eating behavior, and quality of life). Body weight will also be recorded. Any changes in pharmacological treatment (e.g., continuation or discontinuation of GLP-1-RA therapy) will be documented post-intervention and at the 12-month follow-up. Throughout the study, retention and data completion will be monitored, and post-intervention participant feedback, including Likert-scale items on satisfaction, perceived usefulness, ease of participation, and willingness to recommend the intervention to others, will be collected to assess acceptability.
实验性的：16-week Mindfulness-Based Nutrition Group Therapy (MBNGT)
The intervention group will participate in a 16-week MBGNT intervention with nine group sessions, led by a certified nutritionist and lecturer in nutrition psychology with expertise in obesity counseling and mindfulness-based interventions. The first four sessions will be held weekly. Thereafter, the intervals between sessions will be extended as the intervention incorporates additional components such as daily mindfulness exercises, journaling, and tandem peer support. Specifically, from session 4 onward, tandem exchange groups will be implemented and in group session 6, the digital application "insight timer" will be introduced. The app includes guided meditations and exercises designed to enhance emotional awareness and support self-regulation in participants' daily lives. Each group therapy session will include theoretical input, guided practices in meditation and mindful eating, take-home assignments, and journaling activities aimed

大体时间
Dutch Eating Behaviour Questionnaire
大体时间：At week 16 and twelve-months follow-up
Eating behavior will be assessed using the German version of the Dutch Eating Behavior Questionnaire, the Fragebogen zum Ernährungsverhalten II (FEV-II). The questionnaire comprises 30 self-report items and assesses three eating behavior domains: emotional eating, external eating, and restrained eating. Items are rated on a Likert scale and summarized into subscale scores. Higher scores indicate a stronger tendency toward the respective eating behavior style.

Mindful Eating Inventory (MEI)
大体时间：At week 16 and twelve-months follow-up
Mindful eating will be assessed using a self-report questionnaire comprising 30 items rated on a 6-point Likert scale ranging from "almost never" to "almost always". The questionnaire assesses mindful eating across several domains, including accepting and non-attached attitude towards one's own eating experience, awareness of senses while eating, eating in response to awareness of fullness, and awareness of eating triggers and motives. Higher scores indicate a higher level of mindful eating.

Weight Bias Internalization Scale (WBIS-M)
大体时间：At week 16 and twelve-months follow-up
Weight bias internalization will be assessed using the validated modified Weight Bias Internalization Scale (WBIS-M). The WBIS-M is a 10-item self-report questionnaire assessing the extent to which individuals internalize negative weight-related stereotypes and apply them to themselves. Items are rated on a 7-point Likert scale ranging from "strongly disagree" to "strongly agree". Higher scores indicate greater internalized weight bias.

Health-related quality of life will be assessed using the German version of the EQ-5D. The EQ-5D assesses current health status across five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. For each dimension, participants select the statement that best describes their health today, using five severity levels ranging from no problems to extreme problems or inability. In addition, participants rate their overall health today on a visual analogue scale from 0 to 100, where 0 represents the worst imaginable health and 100 represents the best imaginable health. Higher EQ-5D visual analogue scale scores indicate better self-rated health.
