There were significant interactions in the blood glucose (interaction: p < 0.05; F = 6.04; Df = 21), homeostatic model assessment-insulin resistance (HOMA-IR) (interaction: p < 0.01; F = 10.54; Df = 21), T-cho (interaction: p < 0.01; F = 8.10; Df = 30) and leptin levels (interaction: p < 0.05; F = 5.37; Df = 20) between genotype and diet. This evidence concerns the gene LEP and Insulin resistance.
