Fitness | LifestyleCheck: what can you do yourself?

The question 'what can you do yourself?' regarding fitness and lifestyle is addressed by tests like the INFINITY DNA test. These analyses provide insights into genetic predispositions for metabolism, nutrient needs, or exercise response. However, the evidence is mixed: while some gene variants (e.g., FTO for weight regulation, ACTN3 for muscle fiber type) show moderate associations in studies, direct proof that personalized recommendations based on these markers outperform general healthy lifestyle advice is lacking. The offered products often include marketing claims that exceed the scientific basis. What you can do yourself: maintain a balanced diet rich in vegetables, whole grains, healthy fats, and adequate protein; engage in regular exercise (both strength and endurance); prioritize sleep hygiene (7–9 hours); manage stress (e.g., meditation, walks). A DNA test can serve as inspiration but does not replace medical consultation. For specific health concerns or performance goals, clinical lab tests (e.g., blood panels, hormones) are more reliable. The evidence for self-efficacy of such tests is currently rated as 'marketing/mixed'.
