Diabetes Plate Method meal planning guide

The Diabetes Plate Method

The Diabetes Plate Method can help you balance your blood sugar while creating a healthy meal. Using a 9-inch dinner plate, fill:

  • ½ of your plate with non-starchy vegetables such as broccoli, cauliflower, green beans, or salad.
  • ¼ of your plate with lean protein such as poultry, fish, eggs, beans, or tofu.
  • ¼ of your plate with carbohydrate-rich foods such as fruit, whole grains, starchy vegetables, milk, or yogurt.
