Gestational Diabetes Carbs: What to Eat (Best Choices + What to Limit)

A gestational diabetes diagnosis doesn’t mean you have to cut carbs completely (in fact, you shouldn't!). But it does mean carbs may affect your blood sugar differently than they used to — especially as pregnancy hormones ramp up.

Here’s the goal: choose carbs that digest more slowly, keep portions realistic, and pair them well so your blood sugar stays in range.

Julija note: If you’re scared of carbs right now, you’re not alone in this. This isn’t a willpower issue — it’s placenta hormones + insulin resistance. We’ll keep this simple and doable.

A quick note before we list “carbs to limit”

When you see lists like “limit/avoid,” please read them as guidance — not a strict ban list.

With gestational diabetes, it usually comes down to:

• Portion size

• Pairing (protein/fat/fiber)

• Time of day

• Your personal tolerance (which can change week to week)

The only foods that are truly “off limits” are the ones that are generally not recommended in pregnancy overall (and anything your care team told you to avoid). Read more on this topic in our complete What Not to Eat With Gestational Diabetes: A Realistic Guide.

Quick answer: best carbs for gestational diabetes

Most GD mamas do best with higher-fiber, slower-digesting carbs, especially when paired with protein and healthy fats.

Carbs that tend to work best (for many people)

• Non-starchy veggies: leafy greens, cucumber, tomatoes, broccoli, zucchini, peppers, mushrooms

• Beans/lentils/chickpeas (if tolerated)

• Whole grains (measured portions): oats, quinoa, barley, brown/wild rice, whole grain bread

• Lower-GI fruits: berries, apples, pears (pair with protein/fat)

• Plain dairy carbs: milk, plain Greek yogurt (watch portions; avoid sweetened versions)

Carbs that spike more easily (often need smaller portions + better pairing)

• White bread, white rice, regular pasta

• Juice/soda/sweetened drinks

• Pastries, candy, desserts (especially on an empty stomach)

• Ultra-processed snacks that are low fiber + high sugar

Julija note: “Spikes more easily” doesn’t mean “never.” It just means these foods usually need more strategy (or a smaller portion) to work with gestational diabetes.

How many carbs should you eat with gestational diabetes?

Carb targets vary by clinic, country, and your personal blood sugar response.

While recommendations may vary, the general guideline for pregnant women is to consume at least 175 grams of carbohydrates per day. This ensures adequate glucose supply for both maternal and fetal needs, particularly for brain development. A systematic review highlighted that higher carbohydrate quality, such as low-glycemic index (GI) or high-fiber options, can help manage blood sugar levels in gestational diabetes mellitus (GDM) while supporting overall nutritional adequacy.

Choosing the right type of carbohydrates is key to avoiding blood sugar spikes. For example, a randomized controlled trial comparing low-carbohydrate and low-glycemic index diets found that a low-glycemic load diet significantly reduced the risk of macrosomia (large-for-gestational-age infants), a common complication of GDM.

Let’s break it down:

• Simple carbs = Quick digestion → Rapid blood sugar spikes

• Complex carbs = Slow digestion → Steady energy & stable glucose

A common starting point many educators use:

• Main meals: 30–60g carbs

• Snacks: 15–30g carbs

Some clinics also suggest:

• Breakfast: 15–45g

• Lunch/dinner: 45–60g

The key: your meter (or CGM) is your feedback. Your “right” carb amount is the one that keeps you in your healthy range — and it may be lower in the morning and higher later in the day.

If carb counting feels overwhelming: you’re not alone. It’s a tool — not a requirement and definitely not a moral scorecard. If you want a simpler approach (like consistent meals or the plate method) and the bigger picture of how to use carbs without losing your mind, read our guide on Carb counting for gestational diabetes.

Best carbs for gestational diabetes (complex carbs food list)

These are the carbs that tend to be more GD-friendly because they’re higher in fiber and digest more slowly.

1) Non-starchy vegetables (the easiest “carb” for most mamas)

• Leafy greens, cucumber, tomatoes, broccoli, cauliflower, zucchini, peppers, mushrooms, asparagus — all packed with fiber, vitamins, and minerals

2) Whole grains (portion matters)

• Oats, quinoa, barley, bulgur, whole grain bread/wraps, brown or wild rice

3) Beans, lentils, chickpeas (if tolerated)

• Great for fiber + protein, but some mamas spike (or get GI upset) — test and see

4) Fruit (yes, you can still eat fruit)

Focus on lower-GI options and pair them:

• Berries (strawberries, blueberries, raspberries), apples, and pears contain fiber and essential nutrients that slow sugar absorption

Pairing examples:

• Apple + peanut butter

• Berries + plain Greek yogurt

More details in our Fruit guide (best fruits for gestational diabetes and the ones to limit).

5) Dairy carbs (choose unsweetened)

• Plain Greek yogurt, milk, kefir (watch portions; avoid sweetened versions)

6) Nuts & Seeds

– Almonds, walnuts, chia seeds, and flaxseeds are rich in healthy fats, fiber, and protein, making them an excellent snack to help control blood sugar.

Carbs to limit (simple carbs guidance — not a ban list)

These foods are more likely to spike because they’re fast-digesting and lower in fiber.

1) Sugary drinks

• Juice, soda, sweetened iced tea, sweet coffee drinks

2) Refined grains

• White bread, white rice, regular pasta, many baked goods

3) Sweet snacks and desserts

• Cookies, cakes, pastries, candy

4) “Healthy” packaged snacks with hidden sugar

• Granola bars, sweetened yogurt, cereals (many cereals marketed as “healthy” are actually packed with sugar – look for options that are high-fiber and include minimal added sugars per serving)

If you’re choosing packaged foods, a simple rule of thumb:

• Look for higher fiber and lower added sugar

• Check serving size (it’s often smaller than you think)

How to eat carbs without spiking (easy rules)

The key to managing gestational diabetes isn’t eliminating carbs, but rather balancing them with the right nutrients. Effective maternal glucose control is crucial for reducing complications related to gestational diabetes.

1. No naked carbs

   Pair carbs with protein + fat + fiber – this slows digestion and prevents blood sugar spikes

2. Portion first

   Even “healthy carbs” can spike if the portion is big and be cautious with artificial sweeteners as they can be a useful sugar substitute but should be consumed in moderation

3. Breakfast is often the hardest

   Many women are more insulin resistant in the morning, so you may do better with smaller carb portions at breakfast and more carbs later.

Easy carb swaps (trial and error)

If you’re feeling overwhelmed

If you’re newly diagnosed and everything feels confusing, start here:

• Build meals as carb + protein (and ideally add fat + fiber)

• Keep breakfast carbs a bit lower and go heavier on protein

• Test and adjust (don’t guess)

You’ll find lots of helpful resources + meal and snack ideas in our GD Toolkit.

Final thoughts

Managing gestational diabetes isn’t about being perfect — it’s about learning what works for your body.

Start with slower carbs, keep portions realistic, pair carbs with protein/fat/fiber, and use your blood sugar checks as feedback.

Julija note: If today feels hard, that doesn’t mean you’re failing. It means you’re doing something really challenging — while pregnant — and still showing up. That counts.

FAQ: Carbs & Gestational Diabetes

1. Do I have to avoid carbs completely with gestational diabetes?

No. Carbs are essential — both for mom and for the developing baby. The goal is choosing carbs that work for your body and pairing them well.

2. Should I count total carbs or net carbs?

Most providers use total carbohydrate from the nutrition label.

3. Why do I spike even with “healthy carbs”?

Because gestational diabetes is influenced by hormones, time of day, sleep/stress, movement, and portion size. “Healthy” doesn’t always mean “easy on blood sugar.”

4. What foods are truly off-limits?

Mostly the same foods that are generally not recommended in pregnancy overall, plus anything your provider told you to avoid. More on this topic in our complete What Not to Eat With Gestational Diabetes: A Realistic Guide. 

5. Can I eat rice with gestational diabetes?

Often yes — but many mamas do better with smaller portions, brown/wild rice, and always pairing with protein + veggies.

6. Are potatoes or sweet potatoes okay?

Sometimes! Portion + pairing matter. Some people tolerate sweet potatoes better than white potatoes, but it’s individual. Your meter will tell.

7. Can I eat bread with gestational diabetes?

Many do best with whole grain or higher-fiber options, paired with protein/fat (eggs, cheese, nut butter). Mornings tend to be trieckier, so if bread doesn't work well for the first meal of the day, don't be afraid to try it again for other meals.

8. Can I eat pasta with gestational diabetes?

Often yes in a smaller portion, paired with plenty of protein and a fiber-rich sauce. Many mamas do better with chickpea/lentil pasta, or use protein-enriched pastas instead. Read more in our complete Pasta guide for gestational diabetes.

9. Can I eat fruit with gestational diabetes?

Yes! You can still enjoy fruit, but it's best to focus on low-glycemic options like berries, apples, and pears. These fruits have a lower impact on blood sugar and provide fiber, which helps slow glucose absorption. Always pair fruit with a protein or healthy fat to help balance blood sugar levels.
