Fundamentos. El objetivo de presente trabajo es evaluar la composición corporal y el metabolismo energético en mujeres con exceso de peso corporal. Material y métodos. Estudio transversal de intervención no randomizado con 40 mujeres [26 con exceso de peso (G1) y 14 eutróficas (G2)]. Fueron realizadas evaluaciones dietéticas, antropométricas y de la composición corporal (bioimpedancia eléctrica), actividad física (acelerómetro tridimensional) y metabolismo energético (calorimetría indirecta). Resultados. No hubo diferencia en la ingesta energética y en la actividad física entre los grupos. Los parámetros de composición corporal fueron superiores en G1, excepto el agua corporal total. Hubo asociación entre el gasto energético y la composición corporal. La masa corporal magra fue el principal determinante del gasto energético. No hubo diferencia de los parámetros metabólicos entre los grupos, pero se sugiere menor velocidad de oxidación de los nutrientes y mayor eficiencia metabólica en G1. Conclusiones. El exceso de peso corporal se asoció con cambios en la composición corporal y en el metabolismo energético que justifican la acumulación de grasa corporal.Descargas
