We have a lot of great evidence that type 2 diabetes in even (or even most) people can be prevented with lifestyle modification. Since type 2 diabetes is so closely associated with obesity or being overweight, we know that if you reduce your body weight and maintain a healthy body weight, most people wonÕt get type 2 diabetes. We have a lot of research over the years that being more physically active, caloric restriction, making healthy food choices Ð all of those things that lead to weight reduction also reduce the onset of type 2 diabetes in high-risk people. There are also certain medications that can prevent type 2 diabetes in high-risk people. The most common one is called Metformin and there is excellent data that shows that certain people with a risk for type 2 diabetes can reduce that risk by taking Metformin.
