Can ADH1B help with weight loss? The link is indirect and based on limited evidence. ADH1B encodes alcohol dehydrogenase; the rs1229984 T allele slows alcohol metabolism and is associated with reduced alcohol dependence risk (human-observational, ancestry-dependent). Since alcohol contributes calories and impairs fat oxidation, a genetic tendency to drink less could theoretically support weight management. However, no direct studies connect ADH1B variants to weight loss. Effect sizes are small, polygenic, and heavily influenced by lifestyle. MyBody-X DNA tests can detect such variants, but results are not clinically actionable for weight loss. Weight reduction requires a holistic approach to diet, exercise, and behavior. Evidence is mechanistic, not robust. Caveat: No direct evidence for weight loss from ADH1B in the provided context.
