Background: There have been lots of discussion and controversy concerning the difference between Low Carbohydrate Diet (LCD) and Calorie Restriction (CR). The important points include glucose variability, glucose-lowering effect, weight reduction degree and influence on lipid metabolism.
Subjects and Methods: Enrolled subjects were 47 patients with T2DM. Methods included the study for providing subjects CR meal with 60% carbohydrate on day 1-2 and LCD meal with 12% on day 3-14. Daily profile of blood glucose was studied seven times a day on day 2 and day 4. Further, biomarkers including HbA1c, average blood glucose, and M value were investigated and analyzed for mutual correlations.
Results: Subjects were categorized into 4 groups according to the average glucose value, which were 124mg/dL, 160mg/dL, 206mg/dL, and 281mg/dL, respectively. Data in 4 groups were as follows: Number; 12,12,12,11, Male/Female; 6/6, 3/9, 6/6, 5/6, mean age; 51.3, 60.9, 65.3, 60.6 years old, HbA1c; 6.1%, 7.1%, 8.0%, 8.9%, fasting glucose on day 2; 109 mg/dL, 136 mg/dL, 178 mg/dL, 224mg/dL, respectively. Daily profiles of blood glucose in 4 groups on day 4 were remarkably decreased than those of day 2. The levels of M value indicating average blood glucose and mean amplitude of glycemic excursions (MAGE) on day 2 vs 4 were compared in 4 groups, which are 7.1 vs 10.5, 39.7 vs 5.0, 139 vs 15.7, 367 vs88, respectively. Correlations among HbA1c, M value and average blood glucose showed significant correlations (p<0.01).
Discussion and Conclusion: Obtained results showed that the distribution of daily profile of blood glucose in 4 groups is separated. Further similar tendency was observed in HbA1c and M value.
