Key Points
- Fill half your plate with nonstarchy vegetables to stabilize blood sugar and boost fiber intake.
- Pair protein with carbs to slow glucose digestion and stay fuller longer; limit portions for balance.
- Choose complex carbs like whole grains and beans for steady energy and better blood sugar control.
If you’re living with diabetes or prediabetes, your head may be spinning with all the advice out there on how to manage your blood sugar. From food pairings and portions to what to fill up on and what to limit, you can easily spend your evening sorting through rules instead of getting dinner on the table.
While diabetes is complex, creating a blood sugar–friendly meal doesn’t have to be. The American Diabetes Association’s Diabetes Plate follows a simple formula to meet your nutrition needs and support steady blood sugars without measuring, weighing or counting every morsel. Research suggests the plate method is just as effective for blood sugar management as counting carbohydrates and may also support heart-health measures. Keep reading to learn more about this blood sugar–friendly dinner formula along with easy meal ideas to put it into practice, even on busy nights.
The Dinner Formula Dietitians Recommend for Diabetes
Make Half Your Plate Nonstarchy Vegetables
Vegetables are at the foundation of any healthy diet, but with diabetes, nonstarchy vegetables take center stage. Vegetables like potatoes, corn, butternut squash and peas are higher in carbohydrates and can have a bigger impact on your blood sugar, while nonstarchy vegetables like broccoli, cauliflower, carrots, spinach, bok choy and peppers have a different effect. “Beyond adding color to a plate, nonstarchy vegetables can help stabilize blood sugar because they are high in fiber, a carbohydrate humans can’t digest as sugar,” says Lori Watson, M.S., RD, LDN.
Filling half your plate with nonstarchy vegetables can help you feel fuller, slow digestion and stabilize your blood sugar after a meal. Research suggests that eating vegetables before starchy carbohydrates at your meal can lower post-meal blood glucose levels in people with and without diabetes.
Make a Quarter of Your Plate Protein
Filling a quarter of your plate with protein helps you feel fuller, support muscle repair and growth and stabilize your blood sugar. Protein alone doesn’t significantly affect your glucose levels, but eating it alongside carbohydrates lets its blood-sugar benefits shine. “When paired together, protein will slow the rate that glucose is digested and released into the bloodstream. This leads to you feeling full and satisfied for a longer period of time,” says Kate Dwyer, M.S., RD.
Plant proteins like beans, lentils, nuts and soy, as well as dairy, fish, poultry and meat, count toward your protein portion. But while some protein is helpful, more isn’t always better. Eating too much protein at a meal can cause a delayed glucose spike that’s hard to bring down, because high protein levels can increase secretion of glucagon, a hormone that triggers glucose release from the liver.
Make a Quarter of Your Plate Fiber-Rich Carbohydrates
Carbohydrates break down into glucose, which raises your blood sugar, but they still deserve a portion of your plate. As with protein, you’ll want to limit your carbohydrate serving to a quarter of your meal.
“Carbohydrates are the body’s primary source of energy, but not all carbs impact how we feel in the same way,” says Alexis Silver, M.P.H,, RD. Simple carbohydrates like sweets, white bread, pasta, rice and sugar-sweetened drinks digest quickly and often lack nutrients like vitamins, minerals and antioxidants.
For a more nutritious meal and stable blood sugar, reach for complex carbohydrates. “Complex carbohydrates like whole grains, beans and vegetables are rich in fiber and raise blood sugar more steadily, leaving us feeling fuller for longer and providing us with balanced energy throughout the day,” says Silver.
Beyond your dinner, research suggests that increasing fiber intake by 10 grams a day can significantly reduce HbA1C (a marker that indicates average glucose levels over the past three months), fasting glucose and fasting insulin levels.
Dinner Combos to Try
“Don’t overcomplicate the diabetes-friendly plate,” says Dwyer. With this formula, you can easily turn any meal into a blood sugar–friendly option by adjusting your portions. Dwyer makes it even easier by recommending a palm-size portion of lean protein, a fist-size portion of carbohydrates, and filling the rest of your plate with nonstarchy vegetables. “Your meals should taste good and include foods you enjoy,” she says.
Here are a few easy combinations to get your creative dinner juices flowing:
- Grilled Chicken Salad: Fill your plate with leafy greens, then top with grilled chicken and whole-grain croutons. Serve with a bit of grated cheese and a drizzle of dressing on top.
- Roasted Chicken Thighs & Quinoa: Roast boneless, skinless chicken thighs and serve with a scoop of herbed quinoa. Fill the rest of your plate with olive oil-sautéed vegetables like red onion, zucchini and peppers.
- Zoodle Spaghetti & Meatballs: “Reimagine spaghetti and meatballs by filling the base of your plate with zoodles (spiralized zucchini or spaghetti squash), topping with lean beef or turkey meatballs in marinara sauce and pairing with a sensibly portioned slice of crusty whole-wheat or sourdough bread,” Watson suggests.
- Sheet-Pan Salmon: Roast green beans, cherry tomatoes and baby potatoes with lemon garlic-marinated salmon. Keep your potatoes to a quarter of your plate, and fill the rest with nonstarchy green beans and tomatoes.
- Chicken Fajita Bowl: Add a small scoop of rice to a bowl and toss in some taco-marinated chicken, sautéed peppers and onions and a scoop of black beans. Top with crispy romaine, avocado and fresh salsa. Keep in mind that black beans contain protein and carbohydrates, so you can adjust your rice portion as needed.
