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 .
A High-Protein Diet With Resistance Exercise Training Improves Weight Loss and Body Composition in Overweight and Obese Patients With Type 2 Diabetes
OBJECTIVE To evaluate the effects of two low-fat hypocaloric diets differing in the carbohydrate-to-protein ratio , with and without resistance exercise training ( RT ) , on weight loss , body composition , and cardiovascular disease ( CVD ) risk outcomes in overweight/obese patients with type 2 diabetes . RESEARCH DESIGN AND METHODS A total of 83 men and women with type 2 diabetes ( aged 56.1 ± 7.5 years , BMI 35.4 ± 4.6 kg/m2 ) were r and omly assigned to an isocaloric , energy-restricted diet ( female subjects 6 MJ/day , male subjects 7 MJ/day ) of either st and ard carbohydrate ( CON ; carbohydrate : protein : fat 53:19:26 ) or high protein ( HP ; 43:33:22 ) , with or without supervised RT ( 3 days/week ) for 16 weeks . Body weight and composition , waist circumference ( WC ) , and cardiometabolic risk markers were assessed . RESULTS Fifty-nine participants completed the study . There was a significant group effect ( P ≤ 0.04 ) for body weight , fat mass , and WC with the greatest reductions occuring in HP+RT ( weight [ CON : −8.6 ± 4.6 kg , HP : −9.0 ± 4.8 kg , CON+RT : −10.5 ± 5.1 kg , HP+RT : −13.8 ± 6.0 kg ] , fat mass [ CON : −6.4 ± 3.4 kg , HP : −6.7 ± 4.0 kg , CON+RT : −7.9 ± 3.7 kg , HP+RT : −11.1 ± 3.7 kg ] , and WC [ CON : −8.2 ± 4.6 cm , HP : −8.9 ± 3.9 cm , CON+RT : −11.3 ± 4.6 cm , HP+RT : −13.7 ± 4.6 cm ] ) . There was an overall reduction ( P < 0.001 ) in fat-free mass ( −2.0 ± 2.3 kg ) , blood pressure ( −15/8 ± 10/6 mmHg ) , glucose ( −2.1 ± 2.2 mmol/l ) , insulin ( −4.7 ± 5.4 mU/l ) , A1C ( −1.25 ± 0.94 % ) , triglycerides ( −0.47 ± 0.81 mmol/l ) , total cholesterol ( −0.67 ± 0.69 mmol/l ) , and LDL cholesterol ( −0.37 ± 0.53 mmol/l ) , with no difference between groups ( P ≥ 0.17 ) . CONCLUSIONS An energy-restricted HP diet combined with RT achieved greater weight loss and more favorable changes in body composition . All treatments had similar improvements in glycemic control and CVD risk markers
