Why? Because the majority of people with Type II Diabetes (not all) could cure themselves just by eating less! Instead they put a burden on our health care system so they can maintain their habit.

"Exercising regularly and reducing your body weight by about 5% could reduce your risk of getting diabetes by more than 50%."
They list four risk factors, but the BIGGEST risk factor is EATING TOO MUCH.
