If your on the heavier side do you ever worry about diabetes type 2?

The ads are correct -- those factors do increase your risk of developing type II diabetes. But type II diabetes doesn't develop overnight. You're getting regular checkups, that's good, and the checkups thus far have been clear, that's good also, so you don't need to panic. But if you don't make the appropriate lifestyle changes (which it sounds like you have every intention of doing), then down the road the tests might one day come back NOT ok. It's tough/impossible to predict who will develop diabetes and after how long, but there are good data supporting risk factor modification (overweight, inactivity, poor diet, etc). You seem to be right on track, or at least have a good plan of action, so continue to work with your healthcare team to make sure your plan is appropriate for you.
