Low carb diet yields greater decrease in HbA1c
Reductions in HbA1c, fasting plasma glucose, body weight at six months greater with low-carbohydrate diet versus usual diet in individuals with elevated untreated HbA1c
For individuals with elevated glycated hemoglobin (HbA1c), a low-carbohydrate dietary intervention leads to greater reductions in HbA1c than usual diet, according to a US study.
Lead author Kirsten Dorans, an assistant professor of epidemiology at Tulane University in New Orleans and colleagues randomly assigned 150 individuals aged 40 to 70 years with elevated untreated HbA1c into two groups.
One group was assigned a low-carbohydrate intervention (target <40 net g carbohydrates during first three months; <60 net g for months 3 to 6) and the other to usual diet to examine the six-month change in HbA1c.
