A common myth is that the risk variant makes weight loss impossible or that carriers are destined to be obese. In reality, large meta-analyses (e.g., Frayling et al. 2007) show the effect on BMI is modest (≈0.4 kg/m² per risk allele) and can be fully offset by lifestyle interventions. Randomized trials demonstrate that risk-allele carriers lose just as much weight through diet or exercise as non-carriers. Genetics explains only about 2 % of BMI variance; environment, diet, and physical activity are far more influential. Another myth is that FTO directly alters resting metabolic rate – evidence suggests it primarily affects eating behavior (e.g., reduced satiety). Bottom line: FTO is a risk factor, not a destiny.
