How can we prevent diabetes

Many people are at risk for type 2 diabetes. Some people do unhealthy eating, irregular exercise, and even avoid any form of weight control measures that may help them prevent gaining weight. How can we prevent diabetes?

The only way I can think of is to avoid overconsuming products containing sugar or sucrose—that is, things like sweets, juices, sodas, and anything else that is extremely sweet. I assume this is one effective approach, but I’m not sure what other methods might help prevent developing the terrible disease that is diabetes.
