Low-carbohydrate diets in type 2 diabetes

As a strategy for management of type 2 diabetes, low-carbohydrate diets have long been of interest to the scientific community and to the general public, but the topic remains highly controversial. Differences in the definition of low-carbohydrate are a common source of confusion, with dietary prescriptions that can range from ketogenic diets (generally <50 g of carbohydrates per day) to 45% of energy coming from carbohydrates. Additionally, several other issues make the literature difficult to synthesise, including differences in weight loss between intervention and control groups, baseline HbA1c of participants, inconsistent reporting of changes in diabetes medications, and variable retention and adherence to prescribed diets.
