Changing the patients’ lifestyles by modifying their diet through nutrition education programs decreases their body mass index (BMI), hemoglobin A1c (HbA1c), and reverses DM.

In the first session and after third session, the patients’ BMI and HbA1c were measured. According to the results, most of the patients aged 45–64 years, a majority of the patients lived in urban areas (95.2%), were illiterate (33.3%), and were obese (76.2%). Due to the nutrition education program, remarkable decrease was observed in the patients’ high (BMI) and high HbA1c and experienced a mean decrease of (2.6%) from 34.0 ± 5.6 to 31.4 ± 5.2, and HbA1c decreased about (2.0%) on average from 8.9 ± 1.9 to 6.9 ± 0.9.
