Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1 medium zucchini (196g) | 6.1g | 2.0g | 4.1g |
| 1 small (118g) | 3.7g | 1.2g | 2.5g |
| 1 large (323g) | 10.0g | 3.2g | 6.8g |
| 1 cup, chopped (124g) | 3.9g | 1.2g | 2.6g |
| 100 grams | 3.1g | 1.0g | 2.1g |
Net carbs
One medium zucchini has about 4g of net carbs, total carbs (6g) minus fiber (2g). Per 100g, net carbs are about 2.1g, which is very low even by vegetable standards. See the net carbs guide for when to use net instead of total.
For diabetes
One medium zucchini has about 6g of total carbs. For most care teams using total carbs for dosing, that is a negligible load. A large zucchini (323g) reaches about 10g of total carbs, still a modest contribution to a meal. Zucchini is a reliable volume food that adds bulk without a meaningful glucose hit for most people. See the diabetes carb-counting guide for how to handle low-carb vegetables in a meal plan.
Keto and low carb
One medium zucchini has about 4g of net carbs, and a cup of chopped zucchini has about 2.6g. Both fit easily within a strict 20 to 30g daily keto budget. Zucchini is a popular keto staple precisely because you can eat a satisfying portion for very few net carbs. Spiralized zucchini noodles (zoodles) from a large zucchini clock in around 6g of net carbs per full large squash.
Good to know
Zucchini loses water fast when cooked. Sauteing, roasting, or grilling drives off moisture, so a cup of cooked zucchini is denser and slightly higher in carbs per cup than a cup of raw, though the per-gram carb content is the same. Salting raw zucchini and letting it drain before cooking pulls out even more water. Zucchini bread and fritters are a different story. They have added flour, sugar, and binding agents, which push a single slice into the 20 to 30g carb range.
