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 .
Effects of a low glycemic load or a low-fat dietary intervention on body weight in obese Hispanic American children and adolescents: a randomized controlled trial.
BACKGROUND In Hispanic children and adolescents , the prevalence of obesity and insulin resistance is considerably greater than in non-Hispanic white children . A low-glycemic load diet ( LGD ) has been proposed as an effective dietary intervention for pediatric obesity , but to our knowledge , no published study has examined the effects of an LGD in obese Hispanic children . OBJECTIVE We compared the effects of an LGD and a low-fat diet ( LFD ) on body composition and components of metabolic syndrome in obese Hispanic youth . DESIGN Obese Hispanic children ( 7 - 15 y of age ) were r and omly assigned to consume an LGD or an LFD in a 2-y intervention program .  Body composition and laboratory assessment s were obtained at baseline and 3 , 12 , and 24 mo after intervention . RESULTS In 113 children who were r and omly assigned , 79 % of both groups completed 3 mo of treatment ; 58 % of LGD and 55 % of LFD subjects attended 24-mo follow-up . Compared with the LFD , the LGD decreased the glycemic load per kilocalories of reported food intakes in participants at 3 mo ( P = 0.02 ) . Both groups had a decreased BMI z score ( P < 0.003 ) , which was expressed as a st and ard z score relative to CDC age- and sex-specific norms , and improved waist circumference and systolic blood pressure ( P < 0.05 ) at 3 , 12 , and 24 mo after intervention . However , there were no significant differences between groups for changes in BMI , insulin resistance , or components of metabolic syndrome ( all P > 0.5 ) . CONCLUSIONS We showed no evidence that an LGD and an LFD differ in efficacy for the reduction of BMI or aspects of metabolic syndrome in obese Hispanic youth . Both diets decreased the BMI z score when prescribed in the context of a culturally adapted , comprehensive weight-reduction program
