Diabetes Study: Weight Loss No Help

Sometimes you don't want to be ahead of schedule. A major federal study has ended two years early after it became clear that diet and weight loss do nothing to prevent heart attacks and strokes in overweight people with type 2 diabetes. Doctors were surprised, as both previous short-term studies and common sense seem to indicate that weight loss would help prevent heart attacks in these patients. But medical experts caution that this study doesn't mean you should stop exercising: maintaining a healthy weight is always a good thing.
