How do you reduce your blood sugar

Changing your lifestyle could be a big step toward diabetes prevention — and it's never too late to start. Consider these tips.

By Mayo Clinic Staff

Lifestyle changes can help prevent the onset of type 2 diabetes, the most common form of the disease. Prevention is especially important if you're currently at an increased risk of type 2 diabetes because of excess weight or obesity, high cholesterol, or a family history of diabetes.

If you have been diagnosed with prediabetes — high blood sugar that doesn't reach the threshold of a diabetes diagnosis — lifestyle changes can prevent or delay the onset of disease.

Making a few changes in your lifestyle now may help you avoid the serious health complications of diabetes in the future, such as nerve, kidney and heart damage. It's never too late to start.

1. Lose extra weight

Losing weight reduces the risk of diabetes. People in one large study reduced their risk of developing diabetes by almost 60% after losing approximately 7% of their body weight with changes in exercise and diet.

The American Diabetes Association recommends that people with prediabetes lose at least 7% to 10% of their body weight to prevent disease progression. More weight loss will translate into even greater benefits.

Set a weight-loss goal based on your current body weight. Talk to your doctor about reasonable short-term goals and expectations, such as a losing 1 to 2 pounds a week.

2. Be more physically active

There are many benefits to regular physical activity. Exercise can help you:

  • Lose weight
  • Lower your blood sugar
  • Boost your sensitivity to insulin — which helps keep your blood sugar within a normal range

Goals for most adults to promote weight loss and maintain a healthy weight include:

  • Aerobic exercise. Aim for 30 minutes or more of moderate to vigorous aerobic exercise — such as brisk walking, swimming, biking or running — on most days for a total of at least 150 minutes a week.
  • Resistance exercise. Resistance exercise — at least 2 to 3 times a week — increases your strength, balance and ability to maintain an active life. Resistance training includes weightlifting, yoga and calisthenics.
  • Limited inactivity. Breaking up long bouts of inactivity, such as sitting at the computer, can help control blood sugar levels. Take a few minutes to stand, walk around or do some light activity every 30 minutes.

3. Eat healthy plant foods

Plants provide vitamins, minerals and carbohydrates in your diet. Carbohydrates include sugars and starches — the energy sources for your body — and fiber. Dietary fiber, also known as roughage or bulk, is the part of plant foods your body can't digest or absorb.

Fiber-rich foods promote weight loss and lower the risk of diabetes. Eat a variety of healthy, fiber-rich foods, which include:

  • Fruits, such as tomatoes, peppers and fruit from trees
  • Nonstarchy vegetables, such as leafy greens, broccoli and cauliflower
  • Legumes, such as beans, chickpeas and lentils
  • Whole grains, such as whole-wheat pasta and bread, whole-grain rice, whole oats, and quinoa

The benefits of fiber include:

  • Slowing the absorption of sugars and lowering blood sugar levels
  • Interfering with the absorption of dietary fat and cholesterol
  • Managing other risk factors that affect heart health, such as blood pressure and inflammation
  • Helping you eat less because fiber-rich foods are more filling and energy rich

Avoid foods that are "bad carbohydrates" — high in sugar with little fiber or nutrients: white bread and pastries, pasta from white flour, fruit juices, and processed foods with sugar or high-fructose corn syrup.

4. Eat healthy fats

Fatty foods are high in calories and should be eaten in moderation. To help lose and manage weight, your diet should include a variety of foods with unsaturated fats, sometimes called "good fats."

Unsaturated fats — both monounsaturated and polyunsaturated fats — promote healthy blood cholesterol levels and good heart and vascular health. Sources of good fats include:

  • Olive, sunflower, safflower, cottonseed and canola oils
  • Nuts and seeds, such as almonds, peanuts, flaxseed and pumpkin seeds
  • Fatty fish, such as salmon, mackerel, sardines, tuna and cod

Saturated fats, the "bad fats," are found in dairy products and meats. These should be a small part of your diet. You can limit saturated fats by eating low-fat dairy products and lean chicken and pork.

5. Skip fad diets and make healthier choices

Many fad diets — such as the glycemic index, paleo or keto diets — may help you lose weight. There is little research, however, about the long-term benefits of these diets or their benefit in preventing diabetes.

Your dietary goal should be to lose weight and then maintain a healthier weight moving forward. Healthy dietary decisions, therefore, need to include a strategy that you can maintain as a lifelong habit. Making healthy decisions that reflect some of your own preferences for food and traditions may be beneficial for you over time.

One simple strategy to help you make good food choices and eat appropriate portions sizes is to divide up your plate. These three divisions on your plate promote healthy eating:

  • One-half: fruit and nonstarchy vegetables
  • One-quarter: whole grains
  • One-quarter: protein-rich foods, such as legumes, fish or lean meats

When to see your doctor

The American Diabetes Association recommends routine screening with diagnostic tests for type 2 diabetes for all adults age 45 or older and for the following groups:

  • People younger than 45 who are overweight or obese and have one or more risk factors associated with diabetes
  • Women who have had gestational diabetes
  • People who have been diagnosed with prediabetes
  • Children who are overweight or obese and who have a family history of type 2 diabetes or other risk factors

Share your concerns about diabetes prevention with your doctor. He or she will appreciate your efforts to prevent diabetes and may offer additional suggestions based on your medical history or other factors.
