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 .
The effect of protein intake on 24-h energy expenditure during energy restriction.
OBJECTIVE To investigate whether protein intake influences the decline in energy expenditure during energy restriction . DESIGN Cross-over study of three diets of 4.2 MJ/d for 7 days : one diet with 36 % energy as protein and two with 15 % energy as protein , one high in carbohydrate and the other high in fat . SUBJECTS Two men and six women aged 31 - 57 y. BMI 27.B-34.1 kg/m2 . MEASUREMENTS 24-h energy expenditure ( 24-h EE ) , sleeping metabolic rate ( SMR ) and body weight on days 0 and 7 of each diet ; 24-h urinary nitrogen excretion ( 24-h UN ) on days 0 - 7 of each diet . RESULTS 24-h EE and SMR declined on all three diets but the decrease was significantly less on the high protein diet than on the two low protein diets .  Weight loss was similar on all three diets . 24-h UN was less than N intake on the high protein diet but greater than N intake on the two low protein diets . CONCLUSIONS Maintaining protein intake reduces the decrease in energy expenditure during energy restriction
