Resumo: | The aim of this study was to investigate whether protein supplementation helps prevent the loss of fat-free mass during weight loss. The sample was composed of seventy-eight obese adult Japanese women, assigned into four different programs: diet-alone (D, n=24), diet-alone with protein supplementation (DP, n=16), diet-plusexercise (DE, n=17), and diet-plus-exercise with protein supplementation (DEP, n=21). All participants restricted their energy intakes to 1200 kcal/day, and participants in DE and DEP had the exercise session including aerobic exercise of approximately 90 min/day, 3 day/week. Participants enrolled in protein supplementation groups received an additional 14 g/day of protein. Measures on body composition were conducted before and after the program by DXA. All programs yielded significant weight (6.9 to 9.5 kg) and fat (4.1 to 7.6%) reduction. Total fat-free mass significantly decreased in D, DP and DE groups, whereas for DEP group the decrease was not significant. Regional fat-free mass lowered for D and DP groups in leg, arms and trunk. For those in DE group, fat-free mass in trunk was not significantly decreased, and for those in DEP group, fat-free mass in leg and trunk did not differ significantly after the program. However, no significant differences of changes in fat-free mass were observed in comparisons among all groups. Our results confirmed the efficiency of weight loss intervention on fat-mass reduction through diet and exercise. However, fat-free mass does not appear to be preserved by protein supplementation, suggesting that its influence on a short-term weight reduction program is not apparent. |

Setenta e oito mulheres adultas japonesas e obesas foram submetidas a quatro programas diferentes: dieta (D, n=24), dieta com suplementação proteica (DP, n=16), dieta com exercício físico (DE, n=17) e dieta com exercício físico e suplementação protéica (DEP, n=21). A dieta restringiu-se a 1200 kcal/dia e o programa de exercício físico compreendeu atividade aeróbica durante 90 minutos/dia, 3 dias/semana. Os participantes em suplementação proteica receberam 14 gramas/dia de proteína. A avaliação da composição corporal foi conduzida antes e depois de 14 semanas utilizando DXA. Todos os programas resultaram significante redução de massa corporal (6,9 a 9,5kg) e gordura (4,1 a 7,6%), sendo que a massa magra total diminuiu significativamente nos grupos D, DP e DE. No entanto, a redução não foi significativa para o grupo DEP. A massa magra localizada nas pernas, braços e tronco sofreu redução significativa nos grupos D e DP. Para o grupo DE, a massa magra do tronco não reduziu significativamente, assim como para o grupo DEP, a massa magra das pernas e do tronco não alterou significativamente. Entretanto, não foram observadas diferenças significantes na comparação entre os grupos com relação às mudanças obtidas na massa magra. Os resultados confirmam a eficiência da dieta e exercício físico na redução de gordura corporal. Entretanto, este estudo sugere que a suplementação proteica durante programas de emagrecimento de curta duração não se associa à preservação de massa magra.Universidade Federal de Santa Catarina.
