Investigation of Low Carbohydrate Diet for Type 2 Diabetes Mellitus with Elevated Immunoreactive Insulin

Background: There are discussion of Calorie Restriction (CR) and Low Carbohydrate Diet (LCD). Authors and colleagues have continued research concerning LCD, CR and Morbus (M) value. Furthermore, this study also included homeostasis model assessment (HOMA). Subjects and Methods: Subjects enrolled were 40 type 2 diabetes mellitus (T2DM) cases with more than 10 μU/mL of fasting immunoreacitve insulin (IRI). Methods included fundamental tests such as glucose, IRI, HOMA-R, HOMA-β, average blood glucose on day 2 and 14 during CR and LCD meal. Results: Current data were in the following: average age 56.8 ± 12.3 years old, median values are HbA1c 7.2%, fasting glucose 141 mg/dL, IRI 13.1 μU/mL, HOMA-R 4.6, HOMA-β 57.1. Median values on day 2 vs 14 were average blood glucose 160 vs 120 mg/dL, M value 37.1 vs 7.4, Triglyceride 137 vs 97 mg/dL, respectively. M value showed significant correlation with HOMA-R (p<0.05) and HOMA-β (p<0.01). Discussion and Conclusion: The results suggested that LCD showed clinical effect for decreasing of glucose and M value in glucose variability and those patients would have insulin resistance and decreased β cell function. Furthermore, these findings would become basal and useful data for future research in this field.
