A 28‑day plan is not truly personalized – it typically applies generic dietary tweaks (e.g., more omega‑3 for certain gene variants) that have not shown clinical superiority over balanced standard diets in randomized trials (source: PMC12643740).

For longevity, factors like caloric restriction, physical activity, sleep quality, and stress management are far more influential than single gene variants.
