The 25 Best Low-Carb Vegetables (and Keto-Friendly!)


Cruciferous, low-carb vegetables - Dr. Axe

Whether you’re watching your waistline or counting carbs as part of a ketogenic diet or a low-carb diet, adding a few low-carb vegetables to your daily routine can be incredibly beneficial.

What are low-carb vegetables? Low-carb veggies are generally low in total carbohydrates, plus high in fiber.

Fiber is a nutrient that moves slowly through the gastrointestinal tract and remains undigested.

Although the amount of fiber is technically included in the total carb count of a food, it doesn’t impact blood sugar levels, hunger or appetite the same way as most carbs.

Therefore, foods with a higher amount of fiber tend to have a lower number of net carbs, which is calculated by subtracting the grams of fiber from the total grams of carbohydrates.


So what vegetables are high in carbs? And what are the low-carb foods that are considered vegetables?

Keep reading for the 25 best low-carb vegetables you should start stocking up on.

1. Broccoli

Hailing from the same family as cabbage, kale and cauliflower, broccoli is a cruciferous vegetable that’s loaded with health benefits.

Each serving packs in plenty of vitamin C and vitamin K, plus other micronutrients like folate, manganese and vitamin A.

It also definitely deserves a spot on the low-carb vegetables list, with 2.4 grams of fiber per cup and only 3.6 grams of net carbs.

2. Spinach

This leafy green is incredibly versatile and nutritious, making it one of the best low-carb vegetables that you can add to your diet.

A single cup packs in nearly twice the amount of vitamin K you need for the entire day, plus lots of vitamin A, vitamin C, folate and manganese.

It also contains just 0.4 grams of net carbs, which is why spinach is often considered a staple ingredient on a low-carb diet.

3. Asparagus

Also known by its scientific name, Asparagus officinalis, asparagus is a flavorful veggie that doubles as a delicious side dish.

Asparagus is rich in a number of important nutrients, including vitamin K, vitamin A, folate, vitamin C and thiamine.

And with just 1.6 grams of net carbs per cup, mushrooms have definitely earned a top spot on the low-carb vegetables and fruits list.
