Understand how keto vegetables work
If you are building a keto vegetables list to lose weight and improve your health, it helps to know how carbs in vegetables actually work on a ketogenic diet.
On keto, you usually aim for about 20 to 50 grams of carbs per day to stay in ketosis, where your body burns fat for fuel instead of carbohydrates (NatureSweet). That means every vegetable you choose matters.
Two ideas guide your choices:
-
Total vs net carbs
Net carbs = total carbs − fiber. Fiber does not raise blood sugar the same way other carbs do, so high fiber vegetables are often better for keto (NatureSweet). -
Above ground vs below ground
Above ground vegetables tend to be lower in carbs and are usually safe for keto. Below ground vegetables, like potatoes and carrots, often have more starch and need careful portion control or are best avoided (Diet Doctor).
In general, vegetables with fewer than 5 grams of net carbs per 100 grams can usually fit into a keto meal plan without much stress (Diet Doctor).
Build your core keto vegetables list
Start with a short list of vegetables you can reach for almost every day. These are low in net carbs, high in fiber, and easy to use in quick meals.
Leafy greens
Leafy greens are some of the best vegetables for keto. They are low in net carbs and packed with vitamins.
Great options include:
-
Spinach
Spinach is very low in net carbs, with about 1.4 grams of net carbs per 3.5 ounces raw (NatureSweet). You can add it to omelets, salads, sautés, or smoothies. -
Kale
Kale is slightly higher in net carbs than some other greens, about 0.3 grams net carbs per ½ cup in one source and 3.4 grams per cup in another, but it is still considered a strong keto choice (NatureSweet, Wholesome Yum). -
Lettuce
Lettuce, including romaine and other crisp varieties, is very low in net carbs at about 1 gram per cup (NatureSweet). Use it as a salad base or in place of tortillas or buns. -
Arugula and other mixed greens
These greens are also low in net carbs, usually under 2 grams per cup, and add flavor without much impact on your carb budget (Wholesome Yum).
Cruciferous vegetables
Cruciferous vegetables are some of the most satisfying choices on a keto vegetables list because they are hearty and can stand in for starchier foods.
-
Cauliflower
Cauliflower is one of the most popular keto vegetables, with about 3.2 grams of net carbs per 1 cup serving (Wholesome Yum). You can rice it, mash it, or even use it for low carb pizza crusts. -
Broccoli
Broccoli has about 4.5 grams of net carbs and 31 calories per cup and is rich in fiber and vitamins (NatureSweet). It works well roasted, steamed, or in stir fries. -
Cabbage
Cabbage is another dependable option. It is considered a solid keto vegetable, usually under 5 grams of net carbs per 100 grams (Diet Doctor). You can use it in slaws, stir fries, or as a noodle swap in soups.
Everyday low carb favorites
These vegetables are easy to keep on hand and fit smoothly into almost any keto meal.
-
Zucchini
Zucchini has about 2.4 grams of net carbs per 1 cup serving and is very versatile. You can spiralize it into “zoodles,” bake it into casseroles, or slice it for roasting (Wholesome Yum). -
Cucumber
Cucumber contains about 2.95 grams of carbs per 100 grams, which drops to 2.16 grams if you peel it (Medical News Today). It is refreshing in salads and works well as a crunchy snack with dips. -
Asparagus
Asparagus is keto friendly with about 2.5 grams of net carbs and 27 calories per cup, and it provides around 10 percent of your daily fiber needs (NatureSweet). Another source lists it at around 2.4 grams of net carbs per cup, again showing it is a very low carb option (Wholesome Yum). -
Celery
Celery has about 3.32 grams of carbs per 100 grams, plus it is low calorie and provides nutrients like calcium and potassium (Medical News Today). It also contains apigenin, which may help support healthy cell function. -
Mushrooms
Mushrooms are low in carbs and work well in omelets, sautés, and soups. They are listed among the keto friendly vegetables, typically under 5 grams of carbs per 100 grams (Medical News Today).
Add these vegetables in moderation
Some vegetables can still fit your keto vegetables list, but they are a little higher in net carbs. You do not need to avoid them completely, you just want to measure your portions and balance them with lower carb foods.
Tomatoes
Tomatoes are nutrient dense and can still work on keto when you keep portions modest.
-
Grape tomatoes
About 5.51 grams of carbs and 2.1 grams of fiber per 100 grams (Medical News Today). -
Roma tomatoes
About 3.84 grams of carbs and 1 gram of fiber per 100 grams (Medical News Today).
Tomatoes provide potassium, vitamin A, and vitamin C, which support overall health, so you do not need to cut them out completely. Instead, use a few slices on a burger or a small handful in a salad.
Bell peppers, brussels sprouts, and green beans
These vegetables are higher in net carbs than leafy greens but still workable if you track your intake.
-
Bell peppers, brussels sprouts, and green beans are all considered “moderation” vegetables on keto, since they carry more than 5 grams of net carbs per 100 grams in many cases (Diet Doctor).
-
Green beans, for example, have about 2 grams of net carbs per ½ cup serving in one source, which is manageable if you keep portions controlled (NatureSweet).
You might choose one of these per meal, measure your serving, and keep the rest of your plate filled with very low carb vegetables and quality protein.
Onions and flavor vegetables
Onions grow below ground and have more carbs, but they are often used in small amounts for flavor.
- Onions can fit a keto diet when you use them as a seasoning rather than a main ingredient. Caramelized or sautéed onions are easy to overeat, so watch your portions (Diet Doctor).
Garlic, scallions, and shallots fall into the same category. Use them to add flavor to your dishes, not as the bulk of your meal.
Lower carb root alternatives
Most root vegetables are too starchy for a strict keto diet, but a few can work in limited amounts.
According to one source, approximate net carbs per serving are (Wholesome Yum):
- Jicama, about 5.1 grams net carbs
- Rutabaga, about 8.9 grams net carbs
- Celery root (celeriac), about 11.6 grams net carbs
- Radishes, about 2 grams net carbs
These can be occasional substitutes for potatoes, which have over 30 grams of net carbs per serving in comparison. If you miss roasted or mashed potatoes, you might try roasted radishes or mashed rutabaga in small, tracked portions.
Vegetables to limit or avoid on keto
Some vegetables sit outside the usual keto vegetables list because their carb counts climb too high for a daily 20 to 50 gram target.
Starchy vegetables
Vegetables with more than 5 grams of carbs per 100 grams are typically considered starchy and are often limited or skipped on keto to maintain ketosis (Medical News Today).
These usually include:
- Potatoes
- Sweet potatoes
- Most beets
- Parsnips
- Corn
Below ground vegetables in general carry more net carbs, in a range of about 6 to 19 grams per 100 grams, so many people on keto either avoid them or use very small amounts (Diet Doctor).
Legumes and grains
Even though they are sometimes grouped with vegetables in everyday language, legumes and grains are typically not part of a keto vegetables list.
Examples include:
- Peas
- Beans
- Lentils
- Corn
- Quinoa
These foods are all relatively high in carbohydrates and are not usually recommended on a keto diet focused on staying under 20 grams of carbs per day (Diet Doctor).
