Conditions
Summary
This project aims to offer a quantitative and qualitative nutritional approach, along with educational nutritional guidelines for participants with Non-Communicable Chronic Diseases. The main goals are: 1- Regularization of eating habits and windows; 2- Modulation of biochemical, anthropometric, and cardiovascular parameters; 3- Increase in knowledge about healthy eating. In this way, participants will undergo a complete nutritional assessment, comprising anthropometry, biochemistry, clinical, and dietary evaluations.
Eligibility
Inclusion Criteria1
- Age: Adults \>18 years \< 80 years; Diagnosis of obesity, diabetes, and hypertension; Gender: Male and female; Availability to attend quarterly meetings over a period of 18 months; Sedentary.
Exclusion Criteria1

Interventions
Participants will be randomized into two groups to follow either a daytime or nighttime eating window, with normocaloric meal plans based on the Mediterranean diet adapted to Brazilian culture. The first intervention phase will last 6 months, followed by a 3-month washout period during which participants return to their usual eating patterns. After the washout, participants will resume the same eating window for an additional 6 months. A final follow-up assessment will be conducted 3 months post-intervention to evaluate the stability of behavioral changes.
