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 .
Role of carbohydrate modification in weight management among obese children: a randomized clinical trial.
OBJECTIVE To compare the effectiveness and safety of carbohydrate (CHO)-modified diets with a st and ard portion-controlled ( PC ) diet in obese children . STUDY DESIGN Obese children ( n=102 ) aged 7 - 12 years were r and omly assigned to a 3-month intervention of a low-CHO ( LC ) , reduced glycemic load ( RGL ) , or st and ard PC diet , along with weekly dietary counseling and biweekly group exercise .  Anthropometry , dietary adherence , and clinical measures were evaluated at baseline and 3 , 6 , and 12 months . Analyses applied intention-to-treat longitudinal mixed models . RESULTS Eighty-five children ( 83 % ) completed the 12-month assessment . Daily caloric intake decreased from baseline to all time points for all diet groups ( P<.0001 ) , although LC diet adherence was persistently lower ( P<.0002 ) . At 3 months , body mass index z score was lower in all diet groups ( LC , -0.27 ± 0.04 ; RGL , -0.20 ± 0.04 ; PC , -0.21 ± 0.04 ; P<.0001 ) and was maintained at 6 months , with similar results for waist circumference and percent body fat . At 12 months , participants in all diet groups had lower body mass index z scores than at baseline ( LC , -0.21 ± 0.04 ; RGL , -0.28 ± 0.04 ; PC , -0.31 ± 0.04 ; P<.0001 ) , and lower percent body fat , but no reductions in waist circumference were maintained . All diets demonstrated some improved clinical measures . CONCLUSION Diets with modified CHO intake were as effective as a PC diet  for weight management in obese children . However , the lower adherence to the LC diet suggests that this regimen is more difficult for children to follow , particularly in the long term
