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 .
High protein vs high carbohydrate hypoenergetic diet for the treatment of obese hyperinsulinemic subjects
OBJECTIVE : To test the hypothesis that hyperinsulinemic obese subjects would respond differently to changes in the composition of hypoenergetic diets . DESIGN : A 4-week r and omized dietary intervention trial . SUBJECTS : Thirteen male obese hyperinsulinemic normoglycemic subjects were divided into two groups and fed hypoenergetic diets providing 80 % of their resting energy expenditure ( REE ) . One group received a high-protein diet ( HP ; 45 % protein , 25 % carbohydrates , and 30 % fat as percent of dietary energy ) and the other a high-carbohydrate diet ( HC ; 12 % protein , 58 % carbohydrates and 30 % fat ) . MEASUREMENTS : Anthropometry , body composition , fasting serum insulin and lipids , and REE were performed before and after the feeding period . RESULTS : Weight loss was higher in the HP than HC group ( 8.3±0.7 vs 6.0±0.6 kg , P<0.05 ) . There was a decrease in body fat in both groups , whereas body water decreased significantly more in the HP group . REE decreased more in the HC than the HP group ( −384.3±84.6 vs −132.3±51.0 kcal , P<0.05 ) . Serum total cholesterol , triglycerides and LDL cholesterol decreased significantly to a similar extent in both diet groups , while HDL cholesterol was decreased significantly only in the HP group . Mean fasting insulin decreased significantly in both diet groups and reached the normal range only in the HP group . CONCLUSION : A low-carbohydrate ( LC ) , HP hypoenergetic diet could be the diet composition of choice for a weight-reducing regimen in obese hyperinsulinemic subjects
