5. Physical Inactivity
While it goes hand in hand with obesity, physical inactivity can definitely lead to type 2 diabetes, as well. Without ever raising the heart rate to give your metabolism a boost, the body will have very little incentive to work off the meal that you just ate. This can not only lead to being overweight, but it can lead to heart problems and circulatory issues, as well. If you take up a regular workout regimen, chances are that you will lose weight and lower your risk factors of diabetes. Plus, it will help you fit into that new bathing suit you want to wear on your next Caribbean cruise.
