Intervention Based on the Dietary Guidelines for the Brazilian Population for the Treatment of Overweight and Obesity
Sponsor: Federal University of Health Science of Porto Alegre
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.

Interventions
Collective Intervention Based on the Dietary Guidelines for the Brazilian Population
Participants in the intervention group will attend four monthly in-person Food and Nutrition Education sessions based on the Dietary Guidelines for the Brazilian Population. These sessions will facilitate discussions on healthy eating and incorporate activities designed to dispel nutritional myths. The curriculum will address the NOVA classification system, critical appraisal of food labels, and making informed food choices. Additionally, a culinary workshop will feature healthy, affordable recipes. This component aims to enhance culinary skills, broaden dietary repertoire, and ultimately reduce the consumption of ultra-processed foods.
Control Group: Individualized Care
The control group will receive individualized nutritional counseling consisting of four in-person consultations, conducted once monthly over a four-month period. Each session, lasting 50-60 minutes, will be led by a nutritionist. These consultations will focus on establishing goals for dietary habit modification and on developing a personalized nutritional plan to improve overall dietary quality.
