What changed
NIH registered a new clinical trial (NCT07538362) on ClinicalTrials.gov assessing whether collective food and nutrition education activities based on the Dietary Guidelines for the Brazilian Population produce similar benefits to individual nutritional counseling for overweight and obesity treatment.
This registry entry has no regulatory compliance implications. Healthcare researchers and institutions conducting similar dietary intervention studies may find the Brazilian Dietary Guidelines framework of interest as a comparator for obesity management programs.

Intervention Based on the Dietary Guidelines for the Brazilian Population for the Treatment of Overweight and Obesity
N/A NCT07538362 Kind: NA Apr 20, 2026
Abstract
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.
