Intervention Based on the Dietary Guidelines for the Brazilian Population for the Treatment of Overweight and Obesity

Brazil60 participantsStarted 2025-05-01

Plain-language summary

This clinical trial aims to evaluate how group-based food and nutrition education interventions, grounded in the recommendations of the Dietary Guidelines for the Brazilian Population, can improve participants' dietary quality and support the treatment of overweight and obesity. The study seeks to determine whether individuals with overweight and obesity receiving outpatient care who participate in collective food and nutrition education activities achieve benefits similar to those receiving individual nutritional counseling, particularly improvements in dietary intake, clinical parameters, and anthropometric measures. Participants will be divided into two groups and will be required to attend four monthly sessions, complete questionnaires before and after the sessions, and provide consent for the collection of data from their medical records. Researchers will compare the outcomes of participants attending group sessions with those receiving individual care to assess whether collective actions provide similar benefits in improving dietary quality, blood test results, and anthropometric measures.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
