This quasi-experimental research aimed to study the effects of the smart diet program for diabetes control in type 2 diabetes patients. A sample of 30 patients was divided into experimental and comparison groups, with 15 patients in each group. The experimental group received the smart diet program applying the self-regulation concept to design the activities for 12 weeks. The program activities included knowledge of diabetes diet, skill training on self-observation, decision making, self-reaction, and supporting diet control behavior continuously and a follow-up telephone interview was done. Data collection was done during the pre and post intervention program on the 12th weeks by interviewing the subjects and testing of fasting blood sugar and HbA1c level. Data were analyzed by descriptive statistics and inferential statistics, i.e., Chi-square, Paired sample t-test, Independent t-test and Mann- Whitney U test.

The research results showed that after the experimentation, the experiment group gained significantly higher level of perceived self-efficacy, outcome expectation of the diet control, and diet control behavior than before the experimentation (p < .05). Fasting blood sugar and HbA1c level of the experimental group also significantly decreased compared to the pre-experiment program (FBS from 196.9 mg/dl to 141.4mg/dl, p = .014; HbA1c from 8.6 mg/dl to 6.9 mg/dl, p = .002). Therefore, this program should be recommended and applied to other public health facilities with similar context.
