The evidence for genetic markers related to stress response and fitness is weak: many candidate genes (e.g., COMT, FKBP5) show small effect sizes in GWAS and lack sufficient validation to derive personalized training or nutrition recommendations. Therefore, a DNA test cannot reliably predict individual stress susceptibility or guide optimal training.

Fatigue is a multifactorial symptom influenced by sleep quality, stress, diet, exercise, hormonal status, and psychological factors.

Effect sizes are small (often <5% of variance) and the evidence base relies mostly on observational studies (GWAS, association studies), not randomized controlled trials. There are no validated polygenic risk scores that allow personalized recommendations for fatigue reduction from a DNA test. The lifestyle advice provided by MyBody-X (e.g., regarding diet, supplements, or training) should be seen as general health guidance, not evidence-based personalized medicine.
