Twelve-month outcomes of a randomized trial of a moderate-carbohydrate versus very lowcarbohydrate diet in overweight adults with type 2 diabetes mellitus or prediabetes
RCT with 34 particpants. The results suggest that adults with prediabetes or noninsulin-dependent type 2 diabetes may be able to improve glycemic control with less medication by following an ad libitum very low-carbohydrate ketogenic diet compared to a moderate-carbohydrate, calorie-restricted low-fat diet. Additional research should examine both clinical outcomes and adherence beyond 12 months.
