Other parameters under investigation were not affected by either low or high glycaemic indices .
The present systematic review and meta- analysis provides evidence of a beneficial effect of a low glycaemic index/load diet in children and adolescents being either overweight or obese .
The objective of the present systematic review and meta- analysis was to synthesize the available literature data investigating the effects of low glycaemic index/low glycamic load dietary regimens on anthropometric parameters , blood lipid profiles , and indicators of glucose metabolism in children and adolescents .
The Effect of Protein and Glycemic Index on Children's Body Composition: The DiOGenes Randomized Study
OBJECTIVE : To investigate the effect of protein and glycemic index ( GI ) on body composition among European children in the r and omized , 6-month dietary intervention DiOGenes ( diet , obesity , and genes ) family-based study . PATIENTS AND METHODS : In the study , 827 children ( 381 boys and 446 girls ) , aged 5 to 18 years , completed baseline examinations . Families with parents who lost ≥8 % of their weight during an 8-week run-in low-calorie diet period were r and omly assigned to 1 of 5 ad libitum diets : low protein (LP)/low glycemic index ( LGI ) ; LP/high GI ( HGI ) ; high protein (HP)/LGI ; HP/HGI ; and control diet . The target difference was 15 GI U between the LGI/HGI groups and 13 protein percentage points between the LP/HP groups . There were 658 children examined after 4 weeks . Advice on food-choice modification was provided at 6 visits during this period . No advice on weight loss was provided because the focus of the study was the ability of the diets to affect outcomes through appetite regulation . Anthropometric measurements and body composition were assessed at baseline , week 4 , and week 26 . RESULTS : In the study , 465 children ( 58.1 % ) completed all assessment s. The achieved differences between the GI and protein groups were 2.3 GI U and 4.9 protein percentage points , respectively . The LP/HGI group increased body fat percentage significantly more than the other groups ( P = .040 ; partial η2 = 0.039 ) , and the percentage of overweight/obese children in the HP/LGI group decreased significantly during the intervention ( P = .031 ) . CONCLUSIONS : Neither GI nor protein had an isolated effect on body composition . However , the LP/HGI combination increased body fat , whereas the HP/LGI combination was protective against obesity in this sample of children
