Exercise & lose wt: Losing about 10% body weight regular aerobic exercise of at least 150 minutes/week would improve sensitivity to insulin. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats.
