BACKGROUND: Metabolic syndrome is associated with increased risk of cardiovascular events disease and type 2 diabetes. Treatment includes modifications on life style, diet and physical activity. Treatment adherence plays a crucial role in the successful treatment of this disease. OBJECTIVE: To evaluate two models of dietary intervention, and the relationship with adherence to treatment and impact on clinical improvement of patients with metabolic syndrome. METHODS: Randomized clinical trial, lasting four months. Participants were randomized assigned to the intervention or control group. Both groups were instructed to follow a diet for 4 months. Subjects in the intervention group additionally received an intervention package, with metabolic syndrome manual book, telephone counseling and nutrition education leaflets. In both groups nutritional anamnesis, anthropometric assessment, dietary assessment, individualized dietary and biochemical tests were done. RESULTS: Patients who arrived more motivated were those who has the greatest reduction in the values of body mass index, which decreased from 31.7 kg/m² (SD ± 3.9) to 30.9 kg/m² (SD ± 3.8), reduction in waist circumference was 108.1 cm (SD ± 9.8) to 105.9 cm (SD ± 9.5). The statistically significant associations were in the correlation between body mass index, blood glucose and triglycerides, reducing the consumption of whole milk, increased consumption of whole grains and skimmed milk and between the increase in vegetable intake and reducing triglycerides. CONCLUSION: Both groups showed significant improvement in all clinical parameters that was significantly associated with the previous motivation. Patients who arrived more motivated were those who responded better to treatment.
