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 .
A randomized controlled trial to investigate the impact of a low glycemic index (GI) diet on body mass index in obese adolescents
Background The role of a low glycemic index ( GI ) diet in the management of adolescent obesity remains controversial . In this study , we aim to evaluate the impact of low GI diet versus a conventional Chinese diet on the body mass index ( BMI ) and other obesity indices of obese adolescents . Methods Obese adolescents aged 15–18 years were identified from population -recruited , territory-wide surveys . Obesity was defined as BMI ≥95th percentile of Hong Kong local age- and sex-specific references . Eligible subjects were r and omized to either an intervention with low GI diet ( consisting of 45 - 50 % carbohydrate , 30 - 35 % fat and 15 - 20 % protein ) or conventional Chinese diet as control ( consisting of 55 - 60 % carbohydrate , 25 - 30 % fat and 10 - 15 % protein ) . We used r and om intercept mixed effects model to compare the differential changes across the time points from baseline to month 6 between the 2 groups . Results 104 obese adolescents were recruited ( 52 in low GI group and 52 in control group ; 43.3 % boys ) . Mean age was 16.7 ± 1.0 years and 16.8 ±1.0 years in low GI and control group respectively . 58.7 % subjects completed the study at 6 months ( 65.4 % in low GI group and 51.9 % in control group ) . After adjustment for age and sex , subjects in the low GI group had a significantly greater reduction in obesity indices including BMI , body weight and waist circumference ( WC ) compared to subjects in the control group ( all p < 0.05 ) . After further adjustment for physical activity levels , WC was found to be significantly lower in the low GI group compared to the conventional group ( p = 0.018 ) . Conclusion Low GI diet in the context of a comprehensive lifestyle modification program may be an alternative to conventional diet in the management of obese adolescents .
