How to Prevent or Delay Diabetes

Pre-diabetes is a serious medical condition that can be treated. The good news is that the recently completed Diabetes Prevention Program study conclusively showed that people with pre-diabetes can prevent the development of type 2 diabetes by making changes in their diet and increasing their level of physical activity. They may even be able to return their blood glucose levels to the normal range.
While the DPP also showed that some medications may delay the development of diabetes, diet and exercise worked better. Just 30 minutes a day of moderate physical activity, coupled with a 5-10% reduction in body weight, produced a 58% reduction in diabetes.
The American Diabetes Association is developing materials that will help people understand their risks for pre-diabetes and what they can do to halt the progression to diabetes and even to, "turn back the clock." In the meantime, ADA has a wealth of resources for people with diabetes or at risk for diabetes that can be of use to people interested in pre-diabetes.

Nutrition
Knowing what to eat can be confusing. Everywhere you turn, there is news about what is or isn't good for you. Some basic principles have weathered the fad diets, and have stood the test of time. Here are a few tips on making healthful food choices for you and your entire family.
Eat lots of vegetables and fruits. Try picking from the rainbow of colors available to maximize variety. Eat non-starchy vegetables such as spinach, carrots, broccoli or green beans with meals.
Choose whole grain foods over processed grain products. Try brown rice with your stir fry or whole wheat spaghetti with your favorite pasta sauce.
Include dried beans (like kidney or pinto beans) and lentils into your meals.
Include fish in your meals 2-3 times a week.
Choose lean meats like cuts of beef and pork that end in "loin" such as pork loin and sirloin. Remove the skin from chicken and turkey.
Choose non-fat dairy such as skim milk, non-fat yogurt and non-fat cheese.
Choose water and calorie-free "diet" drinks instead of regular soda, fruit punch, sweet tea and other sugar-sweetened drinks.
Choose liquid oils for cooking instead of solid fats that can be high in saturated and trans fats. Remember that fats are high in calories. If you're trying to lose weight, watch your portion sizes of added fats.
Cut back on high calorie snack foods and desserts like chips, cookies, cakes, and full-fat ice cream.
Eating too much of even healthful foods can lead to weight gain. Watch your portion sizes.

Exercise
Exercise is also known as physical activity and includes anything that gets you moving, such as walking, dancing, or working in the yard. You can earn the benefits of being physically active without going to a gym, playing sports, or using fancy equipment. When you're physically fit, you have the strength, flexibility, and endurance needed for your daily activities. Being physically active helps you feel better physically and mentally.
Physical activity can lower your blood glucose (sugar), blood pressure, and cholesterol. It also reduces your risk for heart disease and stroke, relieves stress, and strengthens your heart, muscles, and bones. In addition, regular activity helps insulin work better, improves your blood circulation, and keeps your joints flexible. If you're trying to lose weight, a combination of physical activity and wise food choices can help you reach your target weight and maintain it. All of these benefits can be yours even if you haven't been very active before.

What kinds of physical activity should be part of my routine?
A comprehensive physical activity routine includes three kinds of activities:
Aerobic Exercise
Strength Training
Flexibility Exercises
Aerobic Exercise
Aerobic exercise increases your heart rate, works your muscles, and raises your breathing rate. For most people, it's best to aim for a total of about 30 minutes a day, at least 5 days a week. If you haven't been very active recently, you can start out with 5 or 10 minutes a day and work up to more time each week. Or split up your activity for the day -- try a brisk 10-minute walk after each meal. If you're trying to lose weight, you may want to exercise more than 30 minutes a day. Here are some examples of aerobic exercise:
Take a brisk walk (outside or inside on a treadmill)
Go dancing
Take a low-impact aerobics class
Swim or do water aerobic exercises
Try ice-skating or roller-skating
Play tennis
Stationary bicycle indoors
Strength Training
Strength training, done several times a week, helps build strong bones and muscles and makes everyday chores like carrying groceries easier for you. With more muscle, you burn more calories, even at rest. Here are some ways to do it:
Join a class to do strength training with weights, elastic bands, or plastic tubes
Lift light weights at home
Flexibility Exercises
Flexibility exercises, also called stretching, help keep your joints flexible and reduce your chances of injury during other activities. Gentle stretching for 5 to 10 minutes helps your body warm up and get ready for aerobic activities such as walking or swimming. Your health care team can provide information on how to stretch.
Being Active Throughout The Day
In addition to formal exercise, there are many opportunities to be active throughout the day. Being active helps burns calories. The more you move around, the more energy you'll have. These strategies can help you increase your activity level:
Walk instead of drive whenever possible
Take the stairs instead of the elevator
Work in the garden, rake leaves, or do some housecleaning every day
Park at the far end of the shopping center lot and walk to the store
