Table 1 Effect of diet on weight, BMI, HbA1c and fasting lipids. Sixteen obese patients with type 2 diabetes started at month 0 on a diet with the proportions: 20 % carbohydrates, 30 % protein and 50 % fat. The figures shown are before, 3, 6 and 22 months after the dietary change

From: Low-carbohydrate diet in type 2 diabetes. Stable improvement of bodyweight and glycemic control during 22 months follow-up
