Evidence check: Transferrin in the context of Schlaf

The CLOCK gene variant rs1801260 is linked to circadian rhythm, but evidence for personalized carb timing is weak. Some studies suggest carriers of the risk allele may be more sensitive to late meals, but effect sizes are small and not actionable. A general recommendation: eat more carbs earlier in the day and reduce them in the evening – this benefits most people regardless of genotype. Using a CGM to track your own glucose response can provide practical insights. MyBody-X DNA tests indicate a predisposition, not a certainty. Evidence level: mixed/unclear. Caveat: Do not change diet drastically without professional advice.
