Some type 2 diabetics are able to reduce or eliminate the need for medication using exercise and weight control. Even if you can't achieve that goal though, you can improve your cardiovascular health and thus guard against some of the more extreme complications of diabetes. It is, however, important to exercise safely. If you are taking a sulfonglurea or if you are taking insulin, hypoglycemia can be a problem. If you are just beginning an exercise program, start slowly.
Exercise makes people look good and feel better and it helps with a general sense of well-being.
People with diabetes have too little insulin no matter what. There are no dietary changes you can make to eliminate your need for insulin. If you space out your carbohydrate consumption throughout the day, you might be able to reduce your dosage. Having diabetes does not mean an end to all pleasure. I have just been diagnosed with type 2 diabetes.
