Zucchini Nutrition Facts and Carb Count
For anyone on a ketogenic diet, managing carbohydrate intake is crucial for maintaining ketosis, the metabolic state where the body burns fat for fuel. The good news is that zucchini, a member of the summer squash family, is a keto-friendly powerhouse. Its macronutrient profile makes it a stellar addition to low-carb meal plans.
Raw Zucchini (per 100g):
- Total Carbs: 3.1g
- Dietary Fiber: 1g
- Net Carbs: 2.1g
- Protein: 1.2g
- Fat: 0.3g
- Calories: 17 kcal
This low net carb count means you can enjoy a generous serving of zucchini without worrying about derailing your diet. For context, one medium zucchini contains approximately 6g of total carbs and 4g of net carbs, making it easy to fit into a daily carb limit of 20-50 grams.
Health Benefits That Support a Keto Lifestyle
Beyond its favorable macros, zucchini offers a host of nutritional benefits that are particularly valuable when following a restrictive diet like keto, which sometimes lacks variety in fiber and micronutrients.
- Rich in Nutrients: Zucchini is packed with vitamins A and C, potassium, and antioxidants like lutein and zeaxanthin. Vitamin A supports vision and immune function, while vitamin C boosts immunity and skin health. Potassium is essential for fluid balance and blood pressure regulation.
- Aids Digestion: The high water content and combination of soluble and insoluble fiber in zucchini promote healthy digestion. This can help soften stools, reduce constipation, and feed beneficial gut bacteria, which produce short-chain fatty acids vital for gut health.
- Contributes to Heart Health: Zucchini's soluble fiber, specifically pectin, can help lower LDL ("bad") cholesterol levels. Its potassium content helps regulate blood pressure, reducing the risk of heart disease.
- Supports Weight Management: As a low-calorie, high-volume food with plenty of water and fiber, zucchini can promote feelings of fullness and reduce appetite, which are key for weight loss.
Versatile Ways to Enjoy Zucchini on Keto
Zucchini's mild flavor profile and unique texture make it an incredibly versatile low-carb substitute. It can stand in for many traditional carb-heavy ingredients, allowing you to enjoy familiar dishes without the carb overload. Here are some popular keto-friendly preparations:
- Zoodles (Zucchini Noodles): A spiralizer is all you need to turn zucchini into a perfect low-carb replacement for spaghetti, linguini, or ramen.
- Roasted Zucchini: Sliced or chopped zucchini tossed with olive oil and your favorite herbs and spices can be roasted in the oven until tender and golden brown.
- Zucchini Chips and Fries: For a crunchy snack, thinly slice zucchini into rounds or sticks, coat with a keto-friendly breading (like almond flour and parmesan), and bake or air fry until crispy.
- Zucchini Boats: Halved zucchini can be scooped out and stuffed with a variety of fillings, such as ground beef and cheese or creamy spinach and ricotta, before being baked.
- Keto Zucchini Bread: Shredded zucchini adds moisture to low-carb baked goods like bread and muffins made with almond or coconut flour.

Zucchini and Keto: Essential FAQs
question: How can I ensure my zucchini dishes don't get watery? answer: To prevent soggy zucchini, especially when making zoodles or baked dishes, salt the cut zucchini and let it sit for about 15-20 minutes. Then, pat it dry thoroughly with paper towels to draw out excess moisture before cooking.
question: Is yellow squash also keto-friendly like zucchini? answer: Yes, yellow squash has a similar low-carb profile to zucchini, with roughly 3g of net carbs per 100g serving, making it another great keto-friendly option.
question: Can I eat raw zucchini on the keto diet? answer: Absolutely. Zucchini is perfectly safe to eat raw and can be thinly sliced or spiralized for salads and crudité platters. A good rinse is recommended before consuming raw.
question: What are net carbs and how do they apply to zucchini? answer: Net carbs are the total carbohydrates minus the dietary fiber. Because dietary fiber is not fully digested by the body, it doesn't impact ketosis. Zucchini's relatively high fiber content means its net carb count is low, making it ideal for keto.
question: How does zucchini compare to spaghetti squash for keto? answer: Both are great pasta substitutes. Zucchini has fewer net carbs (~2.1g/100g) than spaghetti squash (~7g/100g), making it more suitable for strict keto diets. However, both can be included depending on your daily carb limit.
question: What are some other low-carb vegetables I can pair with zucchini? answer: Excellent pairings include leafy greens like spinach and kale, cruciferous vegetables like cauliflower and broccoli, and other low-carb options like asparagus, bell peppers, and mushrooms.
question: Can I use frozen zucchini on a keto diet? answer: Yes, frozen zucchini is fine, but it can release more water when cooked. It's best used in recipes where moisture is not an issue, like soups or stews, rather than those requiring a crispy texture.
