Diet and exercise help prevent, control diabetes, studies find

Medication helped somewhat, but lifestyle choices were the most effective factors.

Researchers have been looking at the ways lifestyle affects Type 2 diabetes. Here's what they've found:

What: In 2002, the National Institutes of Health published results from the landmark Diabetes Prevention Program study in the New England Journal of Medicine. In the trial, 3,234 overweight people at risk of developing Type 2 diabetes were split into three groups to test whether lifestyle changes or the drug metformin could prevent the onset of diabetes.

• Group 1 received extensive training in diet and exercise, with goals of exercising 150 minutes per week and losing and keeping off 7% of their body weight.

• Group 2 received 850 milligrams of the diabetes drug metformin twice a day.

• Group 3 received placebo pills.
