Type 1 diabetes can't be prevented. However, the same healthy lifestyle choices that help treat prediabetes, type 2 diabetes and gestational diabetes can help prevent them.
Eat healthy foods: Choose foods low in fat and calories. Focus on fruits, vegetables, whole grains and low fat protein. Look for a variety of foods to prevent boredom.
Get more physical activity: Aim for 30 minutes of moderate physical activity each day. Take a brisk walk, ride your bike or swim laps. If you can’t fit in a long workout, break it up into smaller sessions spread throughout the day.
Lose excess pounds: If you’re overweight, losing even 5 percent of your body weight, for example, 10 pounds if you weigh 200 pounds, can reduce the risk of diabetes. To keep your weight in a healthy range, focus on making long-lasting changes to your eating and exercise habits. Motivate yourself by remembering the benefits of losing weight such as a healthier heart, more energy and improved self-esteem.
Sometimes medicine is an option as well. Oral diabetes drugs such as metformin (e.g. Glucophage, Glumetza and others) may reduce your chances of developing type 2 diabetes. However, healthy lifestyle choices remain the best way to prevent type 2 diabetes.
