In this post, we’ll break down the carb count in zucchini, compare it to other popular veggies, and share why zucchini is a low-carb superstar worth adding to your meals.
Let’s dive in.
Why Zucchini Are Low in Carbs
Zucchini are low in carbs, and there are several solid reasons why.
1. Zucchini Is Mostly Water
About 94% of a zucchini’s weight is water.

When you eat a cup of zucchini, you’re mostly hydrating your body, not loading up on sugars or starches.
This high water content is exactly why zucchini are low in carbs compared to denser vegetables like potatoes or corn.
2. Low Net Carb Count
A cup of sliced zucchini contains roughly 3 grams of total carbohydrates.
Of that, about 1 gram is fiber.
So the net carbs in zucchini come out to around 2 to 3 grams per cup.
For anyone on a keto or low-carb diet, that’s practically nothing.
You could eat two or three cups of zucchini and still stay well within your daily carb limit.
3. Low Glycemic Index
Zucchini have a very low glycemic index, which means they don’t cause rapid spikes in blood sugar.
This makes zucchini a low-carb favorite for people managing diabetes or insulin resistance.
The carbs in zucchini are released slowly, so your body can handle them without the rollercoaster effect.
4. Fiber Slows Carb Absorption
Even though zucchini are low in carbs, the fiber they do contain helps slow digestion.
This means the small amount of carbs present gets absorbed gradually.
So not only are zucchini low in carbs, but the carbs they have are gentle on your system.
How Zucchini Compare to Other Vegetables
To really appreciate how zucchini are low in carbs, it helps to see how they stack up against other common vegetables.
