A genetic test may forecast a child’s likelihood of obesity in adulthood, enabling early interventions. Genetic variants impact fat storage and overeating tendencies. A recent study in Nature Medicine, involving 600 researchers worldwide and data from 5 million individuals, created a polygenic risk score. This score can predict obesity risk in adults before age 5. While genetics play a significant role, lifestyle factors also influence obesity. The test is more effective for individuals of European descent compared to others. Further research is needed to enhance its accuracy across diverse populations. Early intervention through lifestyle coaching could mitigate obesity risks. (Nbcnews)
