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 .
Effects of an ad libitum low-glycemic load diet on cardiovascular disease risk factors in obese young adults.
BACKGROUND The optimal nutritional approach for the prevention of cardiovascular disease among obese persons remains a topic of intense controversy . Available approaches range from conventional low-fat to very-low-carbohydrate diets . OBJECTIVE The aim of this pilot study was to evaluate the efficacy of an ad libitum low-glycemic load diet , without strict limitation on carbohydrate intake , as an alternative to a conventional low-fat diet . DESIGN A r and omized controlled trial compared 2 dietary treatments in obese young adults ( n = 23 ) over 12 mo . The experimental treatment emphasized ad libitum consumption of low-glycemic-index foods , with 45 - 50 % of energy from carbohydrates and 30 - 35 % from fat . The conventional treatment was restricted in energy ( 250 - 500 kcal/d deficit ) and fat ( < 30 % of energy ) , with 55 - 60 % of energy from carbohydrate . We compared changes in study outcomes by repeated- measures analysis of log-transformed data and expressed the results as mean percentage change . RESULTS Body weight decreased significantly over a 6-mo intensive intervention in both the experimental and conventional diet groups ( -8.4 % and -7.8 % , respectively ) and remained below baseline at 12 mo ( -7.8 % and -6.1 % , respectively ) . The experimental diet group showed a significantly greater mean decline in plasma triacylglycerols than did the conventional diet group ( -37.2 % and -19.1 % , respectively ; P = 0.005 ) . Mean plasminogen activator inhibitor 1 concentrations decreased ( -39.0 % ) in the experimental diet group but increased ( 33.1 % ) in the conventional diet group ( P = 0.004 ) . Changes in cholesterol concentrations , blood pressure , and insulin sensitivity did not differ significantly between the groups . CONCLUSION An ad libitum low-glycemic load diet may be more efficacious than a conventional , energy-restricted , low-fat diet in reducing cardiovascular disease risk
