Summary for Patients: Effect of Calorie-Unrestricted Low-Carbohydrate, High-Fat Diet Versus High-Carbohydrate, Low-Fat Diet on Type 2 Diabetes and Nonalcoholic Fatty Liver Disease

What is the problem and what is known about it so far? Type 2 diabetes is common, affecting more than 480million people worldwide. More than half of patients with diabetes also have nonalcoholic fatty liver disease (NAFLD), which can progress to cirrhosis and impair liver function. Prior studies suggest that weight loss improves both diabetes control and NAFLD. Restriction of carbohydrate intake in particular improves the control of blood sugar levels.
