Low-Carbohydrate Diet Reduces A1c in Diabetes, Prediabetes
A 6-month low-carbohydrate diet may reduce A1c levels in people with prediabetes or diabetes, new research suggests. Results from a randomized trial involving 150 adults with untreated A1c of 6.0% to 6.9% were published online October 26 in JAMA Network Open by Kirsten S. Dorans, ScD, assistant professor of epidemiology at Tulane University School of Public Health and Tropical Medicine, New Orleans, Louisiana, and colleagues.

The study participants, all adults aged 40-70 years, were recruited from the New Orleans, Louisiana, area via a mass mailing. Those identified to be at elevated risk for prediabetes or type 2 diabetes via pre-screening were invited for screening. Those with untreated A1c between 6.0% (the World Health Organization's lower cutoff for prediabetes) and 6.9% (the upper bound of the American Diabetes Association's recommended A1c target for people with diabetes) were selected.
