Abstract

Background: Obesity is one of the major public health problems worldwide and contributes to the onset of many diseases, especially the ones related to the metabolic syndrome. The new Dietary Guidelines for the Brazilian population bring a new food classification based on food processing and prioritizes the consumption of fresh or minimally processed foods. Aim: This study analyzed the effects of an educational intervention on obese women, on their weight loss, quality of life, components of the metabolic syndrome and pain. Methods: Randomized controlled pilot study, including 40 obese women, randomized into 2 groups: control group and intervention group. An educational intervention with 5 biweekly meetings of 90 min based on the Dietary Guidelines for the Brazilian population (2014) was carried out involving the intervention group. Parameters related to weight loss, quality of life (SF-36), pain (McGill), bioelectrical impedance analysis, cardiorespiratory fitness, and serum and clinical components of metabolic syndrome, as well as serum concentrations of cytokines were assessed. Results: Significantly decrease of body mass, waist and hip circumferences, basal metabolic rate, extracellular water, body capacitance, and body cell mass were observed in the intervention group after 3 months. Reduction of pain and improvement in quality of life and cardiorespiratory fitness were also observed in the intervention group. There were reductions in waist circumference and glycemia, components of metabolic syndrome. Conclusions: This study showed that the educational intervention can be associated with weight loss, increase in quality of life, reduction of pain, and better metabolic syndrome parameters in obese women.
