To limit blood sugar rise after dinner, recommended portion sizes follow the “plate method” and specific carb-counting guidelines. Keeping portions moderate and focusing on nutrient balance is key for optimal glucose control.
The Plate Method
- Fill half the plate with non-starchy vegetables (e.g., leafy greens, broccoli).healthline+2
- Fill one-quarter with lean protein (e.g., chicken, tofu, fish), about 3–4 ounces or the size of your palm.diabetesfoodhub+2
- Fill the remaining quarter with starchy foods or whole grains (e.g., brown rice, sweet potato, beans), keeping servings modest—usually about ½ to 1 cup, or a fist-sized portion.urmc.rochester+2
Carb and Protein Portion Guidelines
- Limit starchy carbohydrates to about 1/3 to 1/2 cup (15–30 g carbs per meal is typical for many with diabetes, but personal needs vary).diabetescarecommunity+2
- Protein servings are generally 3–4 ounces, roughly the size and thickness of a deck of cards or your palm.cdc+2
- One serving of fruit can be a small apple or 1 cup of berries; dairy is typically ¾ cup yogurt or 1 cup milk, included in the meal if desired.diabetescarecommunity
