Reduction in dopamine receptor D2, has been associated with insufficient brain reward, food addiction, obesity, and type 2 diabetes (T2D). Our aim was to assess whether the genetic variability responsible for this reduction is associated with poor dietary compliance and life style habits in T2D patients. Genetic-analysis was done for 109 T2D individuals who completed a 24-week randomized clinical trial and were assigned to follow either a low-GI or a high-fibre diet. Polymorphisms of TaqIA and C957T were compared with physical and biochemical measures. Regardless of dietary treatments, individuals with the C957T-T allele and the TaqIA-A2 allele were significantly associated with blood pressure reduction. Carriers of the T allele significantly lowered their body mass index (BMI) over the 24-week trial. Our findings suggest that the presence of the TaqIA-A2 allele is associated with a decrease in blood pressure. The C957T-T allele was associated with decrease in pressure and body weight.
