Background: The diagnosis of Type 2 diabetes mellitus is commonly associated with denial followed by a search for instant cure by spiritual intervention or herbal remedies. In the absence of effective health insurance policies in Nigeria, most treatments are paid for as out of pocket expenses, causing many with non-communicable diseases to go into poverty. The aim of this study is to evaluate the efficacy of a wholly Nigerian diet in achieving remission of type 2 diabetes mellitus. Method: Sixty study participants were randomized into matched control (standard of care) and treatment (dietary caloric restriction intervention) groups. Participants were followed for 24 weeks and samples taken at baseline, midline and at the end of the study for analysis. Results: While there was no change in mean HbA1c levels between baseline and at 6 months (8.390 ± 2.0242 compared to 8.140±2.1229), there was a statistically significant decrease in HbA1c value between baseline and at 6 months (7.617±2.0773 compared to 6.017±1.2301). Also, there was significant weight loss in the intervention group (mean waist circumference decreased from 88.82cm to 80.0cm [p=0.001] while BMI decreased from 22.67 to 22.86kg/m2 [p=0.025]).
