Carbs by portion
| Portion | Total carbs | Fiber | Net carbs |
|---|---|---|---|
| 1/2 cup cooked (78g) | 5.5g | 2.0g | 3.5g |
| 1 sprout (21g) | 1.5g | 0.5g | 0.9g |

Net carbs
A half-cup of cooked Brussels sprouts has about 3.5g of net carbs, which is total carbs (5.5g) minus fiber (2g). Their fiber content is proportionally high for a vegetable this small. See the net carbs guide for how fiber affects blood sugar.
For diabetes
A half-cup of cooked Brussels sprouts has about 5.5g of total carbs. The high fiber content relative to their carb load makes the blood sugar effect modest. A full cup at 156g gives you about 11g of carbs and 7g of net carbs, which is still a manageable serving. See the diabetes carb-counting guide.
Keto and low carb
Brussels sprouts are low enough in net carbs to fit keto. A half-cup serving has 3.5g of net carbs. A full cup at about 7g of net carbs is still workable within a 20 to 30g daily budget.
Good to know
Cooking method changes the flavor but not the carbs much. Roasting caramelizes the natural sugars and makes them taste sweeter without meaningfully changing the carb count. Boiling and draining removes very little starch. A key thing to watch is added sauce: a balsamic glaze or honey drizzle can add 5 to 15g of carbs on top.
