Lean mass loss is associated with low protein intake during dietary-induced weight loss in postmenopausal women.
The health and quality -of-life implication s of overweight and obesity span all ages in the United States . We investigated the association between dietary protein intake and loss of lean mass during weight loss in postmenopausal women through a retrospective analysis of a 20-week r and omized ,  controlled diet and exercise intervention in women aged 50 to 70 years . Weight loss was achieved by differing levels of caloric restriction and exercise . The diet-only group reduced caloric intake by 2,800 kcal/week , and the exercise groups reduced caloric intake by 2,400 kcal/week and expended approximately 400 kcal/week through aerobic exercise .  Total and appendicular lean mass was measured using dual energy x-ray absorptiometry . Linear regression analysis was used to examine the association between changes in lean mass and appendicular lean mass and dietary protein intake . Average weight loss was 10.8+/-4.0 kg , with an average of 32 % of total weight lost as lean mass . Protein intake averaged 0.62 g/kg body weight/day ( range=0.47 to 0.8 g/kg body weight/day ) . Participants who consumed higher amounts of dietary protein lost less lean mass and appendicular lean mass ( r=0.3 , P=0.01 and r=0.41 , P<0.001 , respectively ) . These associations remained significant after adjusting for intervention group and body size . Therefore , inadequate protein intake during caloric restriction may be associated with adverse body-composition changes in postmenopausal women
