A new study led by researchers at the University of Massachusetts Amherst suggests that even people with a high genetic risk for type 2 diabetes can substantially reduce their chances of developing the disease by adopting healthier lifestyles—and that more than half of cases might be preventable. Published in the journal Diabetes, the study analyzed data from more than 332,000 adults in the U.K. and found that lifestyle factors such as body weight, physical activity, smoking and diet play a powerful role in shaping diabetes risk, regardless of genetic predisposition.
