Make a commitment to managing your diabetes. Learn all you can about diabetes. Establish a relationship with a diabetes educator, and ask your diabetes treatment team for help when you need it. Choose healthy foods and maintain a healthy weight. Losing just 7 percent of your body weight if you're overweight can make a significant difference in your blood sugar control. A healthy diet is one with plenty of fruits, vegetables, whole grains and legumes, with a limited amount of saturated fat. Make physical activity part of your daily routine. Regular exercise can help prevent prediabetes and type 2 diabetes, and it can help those who already have diabetes to maintain better blood sugar control. Thirty minutes of moderate exercise — such as brisk walking — most days of the week is recommended. A combination of exercises — aerobic exercises, such as walking or dancing on most days, combined with resistance training, such as weightlifting or yoga twice a week — often helps control blood sugar more effectively than does either type of exercise alone.
