Introduction: Acknowledging the promising role of information and technology, a study was planned to determine the effect of personalized human-centered dietary decision support system (PHCDDSS) on dietary knowledge, attitude, practice (KAP), and mean fasting blood sugar (FBS) among participants with type 2 diabetes mellitus (T2DM). Materials and Methods: A community-based randomized control trial was conducted among 400 individuals with T2DM randomized into the 12-month intervention group (PHCDDSS) and 400 to the control (usual care) group. Results: In the control and intervention groups, 84.7% and 87.0% participants completed the follow-up at the end of 12 months. Mean knowledge score showed a significant (P = 0.00) declining trend (from 28.3 to 22.2) in the control group, but increasing (from 28.9 to 35.4) in the intervention group. Unlike knowledge, mean attitude score observed a significant declining trend in both the groups but less in the intervention group. The mean FBS (in mg/dL) trend was found to be insignificantly declining in control (199.2–195.4) and intervention (194.8–183.1) groups but the decline was relatively less in control when compared with the intervention group. Conclusion: In study participants, PHCDDSS proved to be effective in improving knowledge and attitude toward role of diet in managing T2DM. The intervention showed promising effect in reduction of mean FBS and proportion of individuals with sugar control.
