Digbi Health has a robust protocol to address diabetes risk and insulin resistance, which differs substantially from the Food4Me personalization based on rs7903146 as reflected in the Food4Me article (including the decision tree for TCF7L2-based information delivered to level 3 “Diet plus phenotype plus genotype” in Figure S3 in Multimedia Appendix 1) [111]; thus, we would not expect the outcomes of our personalization regarding this SNP to be the same. This evidence concerns the gene TCF7L2 and diabetes mellitus.
