title: Promoting only the consumption of healthy foods may be an alternative stategy for treating patients with the metabolic syndrome.
abstract: OBJECTIVE
  To evaluate the effectiveness of two lifestyle, interventional approaches on metabolic abnormalities and eating habits of patients with metabolic syndrome.
  
  
  METHODS
  This is a randomized controlled trial, involving a 6-month lifestyle intervention. Eighty-eight metabolic syndrome patients were randomized to one of the three groups: (i) "Increase - Decrease" group, (ii) "Increase" group, and (iii) "Minimum intervention" group. All patients received dietary and physical activity advice at baseline; patients in the first two groups also participated in individual counseling sessions. In the "Increase - Decrease" group, all recommended dietary and physical activity goals were targeted, whereas in the "Increase" group, only goals proposing an increase in dietary intake or physical activity were included. Patients received nutrition counseling through seven, one-to-one sessions, conducted every two weeks for the first 2 months, every month for the following 4 months. All participants underwent a full medical and nutritional assessment at baseline and at the end of the intervention.
  
  
  RESULTS
  At 6 months, BMI and waist circumference were improved in the "Increase" and the "Increase - Decrease" groups, compared to the "Minimum Intervention" group. Additionally, "Increase - Decrease" group reduced blood systolic (p=0.017), diastolic pressure (p=0.005) and glucose concentrations (p=0.015). Forty eight percent, 32%, and 19% of the patients in the "Increase - Decrease", "Increase" and "Minimum Intervention" groups, respectively, ceased to fulfill the criteria for the metabolic syndrome (p=0.031).
  
  
  CONCLUSIONS
  Promoting only the increase of the intake of healthy foods did not result in better outcome values compared to a conventional all-food approach.
