Compared with an energy-restricted SP diet , an isocalorically prescribed HP diet provides modest benefits for reductions in body weight , FM , and triglycerides and for mitigating reductions in FFM and REE
BACKGROUND It is currently unclear whether altering the carbohydrate-to-protein ratio of low-fat , energy-restricted diets augments weight loss and cardiometabolic risk markers .
OBJECTIVE The objective was to conduct a systematic review and meta- analysis of studies that compared energy-restricted , isocaloric , high-protein , low-fat ( HP ) diets with st and ard-protein , low-fat ( SP ) diets on weight loss , body composition , resting energy expenditure ( REE ) , satiety and appetite , and cardiometabolic risk factors .
Dietary protein and exercise have additive effects on body composition during weight loss in adult women.
This study examined the interaction of 2 diets ( high protein , reduced carbohydrates vs. low protein , high carbohydrates ) with exercise on body composition and blood lipids in women ( n = 48 , approximately 46 y old , BMI = 33 kg/m(2 ) ) during weight loss . The study was a 4-mo weight loss trial using a 2 x 2 block design ( Diet x Exercise ) . Diets were equal in total energy ( 7.1 MJ/d ) and lipids ( approximately 30 % energy intake ) but differed in protein content and the ratio of carbohydrate : protein at 1.6 g/(kg . d ) and < 1.5 ( PRO group ) vs. 0.8 g/(kg . d ) and > 3.5 ( CHO group ) , respectively . Exercise comparisons were lifestyle activity ( control ) vs. a supervised exercise program ( EX : 5 d/wk walking and 2 d/wk resistance training ) . Subjects in the PRO and PRO + EX groups lost more total weight and fat mass and tended to lose less lean mass ( P = 0.10 ) than the CHO and CHO + EX groups . Exercise increased loss of body fat and preserved lean mass . The combined effects of diet and exercise were additive for improving body composition . Serum lipid profiles improved in all groups , but changes varied among diet treatments . Subjects in the CHO groups had larger reductions in total cholesterol and LDL cholesterol , whereas subjects in the PRO groups had greater reductions in triacylglycerol and maintained higher concentrations of HDL cholesterol . This study demonstrated that a diet with higher protein and reduced carbohydrates combined with exercise additively improved body composition during weight loss , whereas the effects on blood lipids differed between diet treatments
