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 .
Effects of protein versus simple sugar intake on weight loss in polycystic ovary syndrome (according to the National Institutes of Health criteria).
OBJECTIVE To compare the effects of protein vs. simple sugars on weight loss , body composition , and metabolic and endocrine parameters in polycystic ovary syndrome ( PCOS ) . DESIGN A 2-month , free-living , r and omized , single-blinded study . SETTING University PCOS clinic . PATIENT(S ) Thirty-three patients with PCOS . INTERVENTION(S ) To achieve a final energy reduction of 450 kcal/day , first the daily energy intake was reduced by 700 kcal ; then a 240-kcal supplement containing either whey protein or simple sugars was added . MAIN OUTCOME MEASURE(S ) Changes in weight , fat mass , fasting glucose and insulin , plasma lipoproteins , and sex steroids . RESULT ( S ) Twenty-four subjects ( 13 in the simple sugars group and 11 in the protein group ) completed the study . The protein group lost more weight ( -3.3 + /- 0.8 kg vs. -1.1 + /- 0.6 kg ) and more fat mass ( -3.1 + /- 0.9 kg vs. -0.5 + /- 0.6 kg ) and had larger decreases in serum cholesterol ( -33.0 + /- 8.4 mg/dL vs. -2.3 + /- 6.8 mg/dL ) , high-density lipoprotein cholesterol ( -4.5 + /- 1.3 mg/dL vs. -0.4 + /- 1.3 mg/dL ) , and apoprotein B ( -20 + /- 5 mg/dL vs. 3 + /- 5 mg/dL ) . CONCLUSION ( S ) In patients with PCOS , a hypocaloric diet supplemented with protein reduced body weight , fat mass , serum cholesterol , and apoprotein B more than the diet supplemented with simple sugars
