More than 21 million people in the U.S. have diabetes, and 54 million more have pre-diabetes. Unfortunately, obesity has led too much of this increase.

For people who have Type 2 diabetes, your body either can no longer produce enough insulin to maintain a healthy blood glucose level, or it is no longer effective.

There is evidence that shows that our body's fat cells are more insulin resistant than muscle cells. It makes sense when you think about it. So, if someone is obese and carries a lot more fat, their insulin will also become less effective in dealing with blood sugar.

To reduce your risk of getting Type 2 diabetes, or to help maintain it, you should lose the extra weight. Even 10 pounds will give your body a huge boost in fighting against Type 2 diabetes.

You don't have to go to the gym and join an aerobics class, or lift weights and sweat like crazy. You can begin losing the extra weight just by walking every day. Start a simple walking program and within 2 weeks you'll notice improvement. Start off slowly and work your way up to longer distances. The important thing is to just start.

An added health benefit to getting exercise is that your blood pressure and cholesterol will also be healthier. So it's not only Type 2 diabetes that benefits, but many other areas in your overall health as well.

If you're obese and have Type 2 diabetes, I urge you to make a commitment. Start an exercise routine and fight the effects of this terrible disease. You can lead a happy and healthy life.
