So far, despite a number of research studies now underway, there are no definitive answers on how to prevent Type 1 diabetes. Type 2 diabetes is another story. You can reduce many of the risk factors that increase your chances for developing the condition. Poor lifestyle habits such as a bad diet and lack of exercise can increase your chances for getting diabetes. Other nonnutrition related risk factors for Type 2 diabetes include being over the age of 45, having a parent or sibling with the disease, being of Latino, Native American, African American, or Pacific Islander descent, and, in a woman, having polycystic ovarian syndrome.
Furthermore, there's strong evidence that even modest weight loss and exercise can significantly reduce the onset of Type 2 diabetes in people with an impaired fasting glucose (IFG) or impaired glucose tolerance (IGT). In one study, individuals who lost 5 to 7 percent of their body weight and walked for 150 minutes each week reduced their risk of developing Type 2 diabetes by 58 percent.
