Keywords:type 2 diabetes mellitustype 2 diabetes mellitus, Health literacy, Low carbohydrate diet
This nonequivalent control group pretest-posttest design quasi-experimental research aimed to assess the effect of a low carbohydrate diet for controlling blood sugar levels in type 2 diabetes patients. The population was patients of type 2 diabetes who lived in Bangrakam district, Phitsanulok province and were diagnosed by a physician, not more than 3 months. A total of 43 participants were selected purposively and divided into 2 groups. The experimental group (n=20) participated in the low carbohydrate diet program and health behavior promotion model. The comparison group (n=23) received usual care. The duration of the study was 9 months. The data were analyzed using descriptive statistics, Fisher’s exact test, t-test and repeated measure ANOVA. The results showed that the experimental group had a significantly decrease in HbA1C levels after 9 months (p< 0.05). The experimental group had a significant decrease in fasting blood sugar levels, triglyceride levels and body mass index (p< 0.05). Cholesterol, LDL-C levels and glomerular infiltration rates were not differences between the experiment and the comparison groups. The low carbohydrate diet program and health behavior promotion model were more effective to improve fasting blood sugar levels, HbA1C levels, and body weight than usual care
