Vigorous Exercise vs. Moderate- Which is best for diabetes prevention?

Many have the idea that the only kind of exercise is vigorous exercise.  If you are not running a 1/2 marathon, training for one, or lifting heavy weights followed by a vigorous treadmill session, you are not getting a good enough work out.  Oftentimes this type of thinking is due to advertising and media hype on high intensity work out programs which promise insane results. They sell off the shelves, but do the buyers of these video home workouts actually stay fit, stay committed, or even follow thru with them in the first place?

Research shows that the most intense programs may not be as beneficial as mild to moderate activity. It’s been proven time and time again that the biggest gains are seen when going from a sedentary lifestyle, to one with moderate exercise and better diet.
The same can be said for diabetes prevention.  Robert McGarrah, a cardiologist and medical instructor at Duke University School of Medicine says,  “We have found that moderate-intensity activity improves insulin sensitivity more than vigorous-intensity activity in both obese and overweight individuals and in those with pre-diabetes.”  It looks like the “clearance of fat deposits in the muscle,”  is more likely achieved from a moderate level of exercise and healthy diet.
