Pumpkin is one of the lowest-carb starchy vegetables you can eat. A cup of raw pumpkin cubes has just 7.5 grams of total carbohydrates and only 30 calories, putting it well below most other orange-fleshed vegetables and making it a surprisingly friendly option for people watching their carb intake.
Carbs in Raw vs. Canned Pumpkin
The form of pumpkin you use changes the numbers significantly. One cup of raw pumpkin cubes contains 7.5 grams of carbohydrates, 3 grams of sugar, and 0.6 grams of fiber. It’s mostly water, which is why the carb count stays so low for a generous serving.
Canned pumpkin puree is more concentrated. Because the water has been cooked off, one cup of unsweetened canned pumpkin packs 19.8 grams of total carbohydrates. The tradeoff is that you also get 7.1 grams of fiber per cup, which brings the net carbs (total carbs minus fiber) down to about 12.7 grams. That fiber also means canned pumpkin keeps you fuller and has a gentler effect on blood sugar than the raw carb number might suggest.
One important distinction at the grocery store: plain canned pumpkin and pumpkin pie filling are not the same product. Pumpkin pie filling (sometimes labeled “pumpkin pie mix”) can contain around 48 grams of added sugar per cup before you even add it to a recipe. Always check the label. Plain canned pumpkin should list only pumpkin as an ingredient.
How Pumpkin Compares to Other Vegetables
The easiest way to see how low-carb pumpkin really is: compare it to sweet potato, the vegetable people most often swap it with. One cup of cubed sweet potato has 27 grams of carbohydrates. One cup of cubed pumpkin has 7.5 grams. That’s less than a third of the carbs for a similar serving size. Sweet potato does deliver more fiber per cup (4 grams vs. 0.6 grams), but the net carb gap is still dramatic.
Pumpkin also comes in well below other common starches like butternut squash (roughly 16 grams per cup) and corn (about 27 grams per cup). It sits closer to non-starchy vegetables like bell peppers and tomatoes in terms of carb density, even though most people think of it as a starchy food.
Pumpkin on a Keto or Low-Carb Diet
If you’re following a ketogenic diet with a daily limit around 20 to 30 grams of net carbs, pumpkin can fit, but portion size matters. A half-cup serving of cooked pumpkin contains roughly 4.5 to 5 grams of net carbs depending on the variety. That’s a meaningful chunk of a strict keto budget, but it’s entirely workable if you plan around it.
A practical approach is using pumpkin as a flavoring rather than a base. A couple of tablespoons of pumpkin puree stirred into a smoothie, soup, or baked good adds that rich, earthy flavor without pushing your carb count very far. You don’t need a full cup to get the taste.
What About Pumpkin Seeds?
Pumpkin seeds (pepitas) have a different nutritional profile from the flesh. A one-ounce serving of dried, hulled pumpkin seeds contains about 5 grams of total carbohydrates and 1.1 grams of fiber, leaving roughly 4 grams of net carbs. They’re also a solid protein source at nearly 7 grams per ounce. For snacking on a low-carb diet, pumpkin seeds are one of the better options among nuts and seeds.
Why Pumpkin’s Carb Profile Matters
Beyond the raw numbers, the type of carbohydrates in pumpkin works in your favor. Much of pumpkin’s carb content comes with fiber and water, which slows digestion and prevents the kind of rapid blood sugar spike you’d get from refined carbs. Pumpkin also delivers a high concentration of carotenoids (the pigments that give it that orange color and support eye health and immune function), plus about a fifth of your daily iron needs per cup of the canned version. You’re getting a lot of nutrition for very few carbs.
For most people, pumpkin is one of those rare foods that works across almost every dietary pattern. Whether you’re counting carbs, managing blood sugar, or just trying to eat more vegetables, a cup of pumpkin fits comfortably into your day without requiring much negotiation with the rest of your meals.
