What to watch with FOXO3 and blood sugar?

The FOXO3 variant rs2802292 is associated with longevity, not directly with blood sugar levels. There is some evidence that FOXO3 influences insulin signaling and glucose homeostasis, but the effect size is small and population-dependent. A DNA test for this variant does not predict your current blood sugar risk – fasting glucose, HbA1c, and lifestyle factors like diet and exercise are far more relevant. Be wary of claims that a FOXO3 result requires a special diet or supplements. Evidence is moderate (human-observational/GWAS). Caveat: the variant is common, but its impact on blood sugar is not clinically established. Focus on proven measures: high-fiber diet, regular physical activity, and weight management.
