Abstract

The aim was to assess the long-term effect of a loose restriction of carbohydrate intake (carbohydrate-reduced diet: CARD) compared to a conventional diet (CD) in type 2 diabetes. One hundred and thirty-three type 2 diabetic outpatients followed the CD (n=57, 1734+/-410 kcal, carbohydrate:protein:fat ratio=57:16:26) or CARD (n=76, 1773+/-441 kcal, carbohydrate:protein:fat ratio=45:18:33) according to their own will, and were followed up for 2 years. Glycemic control, body mass index (BMI), serum cholesterols and dose of antidiabetic drugs were assessed at baseline and after 1 and 2 years. At baseline, hemoglobin A1c (HbA1c) and BMI levels were 7.1+/-1.0% and 24.2+/-2.9, respectively, in the CD group, and 7.4+/-1.1% and 25.1+/-3.4 in the CARD group, showing no significant differences. During the 2-year follow-up period, HbA1c levels were significantly improved in the CARD group (CD: 7.5+/-1.3%, CARD: 6.7+/-0.6%, P<0.001), and BMI decreased more significantly in the CARD group (CD: 23.8+/-3.0, CARD: 23.8+/-3.5, P<0.001). The doses of sulfonylureas clearly tapered, and serum cholesterol profiles improved significantly with the CARD. Our results warrant a long-term and large-scale randomized study of the diet for type 2 diabetes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
