The nutritional transition in Brazil demands the development of contexts and environments of healthy lifestyles promotion. This study aimed to evaluate the effectiveness of a nutritional intervention associated with physical activity practice among individuals from a Health Promotion Service of Belo Horizonte (MG). The intervention was carried out in six months with normal weight or overweight adults and normal weight elderly. Socio-demographic and economic condition was evaluated before and after this period in addition to health profile, food consumption (eating habits and food frequency questionnaire) and anthropometry. The sample included 20 subjects, 95% women, 75% adults, 52.0±12.9 years. Initially, evaluation revealed occurrence of inadequate eating habits and 30% of overweight among participants. After the nutritional intervention period, there were no differences regarding eating habits, but an increase in the adequacy of processed meats consumption was verified (p=0.016). Furthermore, a reduction in body weight (62.6±8.2 versus 61.7±8.8, p=0.032), waist circumference (82.5±8.2 versus 78.9±6.2; p=0.002) and waist-to-hip ratio (0.82±0.07 versus 0.79±0.05, p=0.016). The intervention was effective for anthropometry changes and reduction in processed meats consumption, highlighting the importance of these services for the population health promotion.
