Diabetic Medicine — McArdle PD, et al. | November 16, 2018
Using data collected via search of the Medline, EMBASE and CINAHL databases (between 1976 and April 2018), researchers studied the impact of carbohydrate restriction on glycemic control among individuals with type 2 diabetes. A total of 1,402 randomized controlled trials were identified, ow which met the inclusion criteria (representing 2,132 individuals for the primary outcome). According to the results of this systematic review and meta-analysis, no overall pooled effect on HbA1c was found in support of restricting carbohydrate. However, restricting carbohydrates to 50–130 g daily had beneficial effects on HbA1c in trials of up to 6 months.
