Several GWAS and candidate-gene studies have linked variants such as rs1801260 to higher BMI, altered eating patterns, and reduced weight loss success. However, effect sizes are small and replication across cohorts is inconsistent. There is no strong evidence that a specific CLOCK variant can predict individual weight loss outcomes or that chrono-nutrition strategies (e.g., time-restricted feeding) can fully override genetic predisposition. Most evidence is observational or GWAS-based; randomized controlled trials stratifying by CLOCK genotype are lacking. Therefore, the evidence level is best described as 'gwas' or 'human-moderate'. For consumers, direct-to-consumer genetic tests reporting CLOCK variants do not provide actionable clinical guidance. A consistent sleep-wake schedule and balanced diet remain the cornerstone of weight management, regardless of genotype. Caveat: circadian genetics is polygenic; single SNPs explain minimal variance.","area":"gesundheit","canonical_id":"gesundheit:canonical-576292681b5f2172c6e0d980","id":"public-36782bc27603e1366e84f163","kind":"qa","language":"en","publication_status":"existing_native_answer_privacy_screened_sources_pending","question":"Evidence check: CLOCK in the context of Abnehmen","score":26.2662207,"snippet":"The CLOCK gene is a core component of the circadian clock.
