Obesity contributes initiation of type 2 diabetes. Low GI diets have been recommended in some countries for weight loss and management of type 2 diabetes. However, there are still controversial to use of low glycemic index (GI) diet in weight management and glycemic control. A meta‐analysis of randomized intervention studies was performed to measure if low GI diet, compared with high GI or traditional diets, can improve weight loss and glycemic control in overweight or obese adults with type 2 diabetes. Literature searches identified 7 randomized studies (3 randomized cross‐over and 4 randomized parallel trials) with a total of 331 subjects who met strict inclusion criteria. Meta‐analyses indicated no beneficial effects of low GI diets on weight loss and HbA1c with a standardized mean difference of −0.148 units (95% CI: −0.372, 0.077) and 0.047 (95% CI: −0.216, 0.309), respectively. Low GI diet was not successful in enhancing weight reduction and glycemic control in overweight or obese patients with type 2 diabetes. Further studies should be conducted in longer‐term, larger randomized controlled trials.
