No significant changes were observed for blood lipids , anthropometric measures , HbA1c and fasting glucose .
The present systematic review provides evidence for beneficial effects of long-term interventions administering a low glycemic index/load diet with respect to fasting insulin and pro-inflammatory markers such as C-reactive protein which might prove to be helpful in the primary prevention of obesity-associated diseases
AIM The aim of the present meta- analysis was to investigate the long-term effects of glycemic index-related diets in the management of obesity with a special emphasis on the potential benefits of low glycemic index/load ( GI/GL ) in the prevention of obesity-associated risks .
Reduced glycemic index and glycemic load diets do not increase the effects of energy restriction on weight loss and insulin sensitivity in obese men and women.
Reducing the dietary glycemic load and the glycemic index was proposed as a novel approach to weight reduction . A parallel- design , r and omized 12-wk controlled feeding trial with a 24-wk follow-up phase was conducted to test the hypothesis that a hypocaloric diet design ed to reduce the glycemic load and the glycemic index would result in greater sustained weight loss than other hypocaloric diets . Obese subjects ( n = 29 ) were r and omly assigned to 1 of 3 diets providing 3138 kJ less than estimated energy needs : high glycemic index ( HGI ) , low glycemic index ( LGI ) , or high fat ( HF ) . For the first 12 wk , all food was provided to subjects ( feeding phase ) . Subjects ( n = 22 ) were instructed to follow the assigned diet for 24 additional weeks ( free-living phase ) . Total body weight was obtained and body composition was assessed by skinfold measurements . Insulin sensitivity was assessed by the homeostasis model ( HOMA ) . At 12 wk , weight changes from baseline were significant in all groups but not different among groups ( -9.3 + /- 1.3 kg for the HGI diet , -9.9 + /- 1.4 kg for the LGI diet , and -8.4 + /- 1.5 kg for the HF diet ) . All groups improved in insulin sensitivity at the end of the feeding phase of the study . During the free-living phase , all groups maintained their initial weight loss and their improved insulin sensitivity . Weight loss and improved insulin sensitivity scores were independent of diet composition . In summary , lowering the glycemic load and glycemic index of weight reduction diets does not provide any added benefit to energy restriction in promoting weight loss in obese subjects
