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 vs. carbohydrate-rich diets on fuel utilisation in obese women during weight loss.
BACKGROUND Energy restriction is a common therapeutic approach for weight reduction , but the most effective macronutrient distribution of the hypoenergetic diet as well as the role of the metabolic processes involved require further investigations . OBJECTIVE To study the effect of a high protein ( HP ) hypoenergetic diet compared with a high carbohydrate ( HC ) hypoenergetic diet on fuel utilisation changes during the weight loss process in obese women . DESIGN Eleven obese ( BMI > 30 ) women were r and omly assigned to a 10w dietary intervention study comparing HP ( 30 % protein ) or HC ( 55 % carbohydrate ) energy restricted diets providing 30 % energy fat content . Substrate utilisation was evaluated by indirect calorimetry . Body weight and composition ( Bod Pod ) and blood measurements were performed before and after weight loss . RESULTS On average , the individuals on the HP dietary group lost 4.4 kg more than those in the HC program ( p<0.50 ) , which was mainly due to a fat mass loss ( 3.7 kg , p<0.05 ) with no statistical differences in lean body mass reduction . These losses were accompanied by a significant decrease in fasting leptin in the HP group ( -52 % ; P<0.05 ) . On the other h and post-absorptive lipid oxidation decreased in the HC group ( -48 % ) and remained unchanged in the HP groups . CONCLUSIONS The replacement of some dietary carbohydrate by protein in energy restricted diets , improves weight and fat losses and specifically promotes lipid oxidation in the fasting state , without major different in lean body mass depletion
