A low-carbohydrate diet gives slightly better control of glucose metabolism than a low-fat diet in type 2 diabetes. In a 2019 consensus report on nutrition therapy for adults with diabetes and prediabetes the American Diabetes Association (ADA) states ""Reducing overall carbohydrate intake for individuals with diabetes has demonstrated the most evidence for improving glycemia (blood sugar) and may be applied in a variety of eating patterns that meet individual needs and preferences."", it also states that reducing overall carbohydrate intake with low- or very low- carbohydrate eating plans is a viable approach.
