FOXO3 is a gene linked to longevity and cellular stress resistance. Certain variants (e.g., rs2802292, G allele) have been associated with a higher likelihood of reaching advanced age in population studies. However, the effects are small and ancestry-dependent. A FOXO3 genotype from a MyBody-X test is not a medical diagnosis and cannot predict individual lifespan. The gene's activity is influenced by lifestyle factors such as caloric restriction, exercise, and oxidative stress. In practice, a 'favorable' genotype does not mean you can ignore diet and exercise; conversely, an 'unfavorable' genotype is no cause for alarm. Evidence comes from GWAS and observational studies, not from randomized interventions. MyBody-X tests are lifestyle tools, not medical devices. For health concerns, consult a doctor.
