CircleDNA's Premium Test includes personalised reports on Obesity risk. See your genetic risk →
Obesity has a substantial genetic component with heritability estimates around 40–70%. The FTO gene variant is the most common genetic risk factor.
How Genetic Is Obesity?
Genetics plays a meaningful role in Obesity, with heritability estimated at around 60%. However, environmental factors — including diet, lifestyle, and exposure — also significantly influence risk.
Key genes associated with Obesity: FTO,MC4R,LEP,LEPR. Variants in these genes have been identified through genome-wide association studies (GWAS) and clinical research as influencing susceptibility or severity.

Does Family History Matter for Obesity?
Family history does matter. Having close relatives with Obesity can increase your personal risk, though it is not deterministic. Maintaining a healthy lifestyle and regular screening remain important regardless of family background.
