People who have low levels of the good HDL cholesterol and store fat primarily in their bellies are at high risk for diabetes.

A study from Kansas State University shows that exercise helps to prevent diabetes by raising blood levels of the good HDL cholesterol and reducing the amount of fat in the belly. People who are at risk for diabetes, have their blood sugars rise too high after meals, which calls out extra insulin that lowers blood levels of the good HDL cholesterol and causes fat to be deposited in the belly.

The only places you can store extra sugar are in your liver and muscles. Exercise uses up sugar from muscles so that after you eat, sugar goes from your intestines into your bloodstream and then directly into empty muscles. If you don't exercise, sugar goes into your blood stream and stays there, calling out extra insulin that lowers HDL and increases belly fat. See report #D222.
