Keto vegetables – the best and the worst
- Vegetables growing above ground are lower carb and can be good keto options.
- Vegetables growing below ground contain more carbs, so you’ll have to be more careful with them (especially potatoes).
Like any rule it is not perfect, so have a look below.
All numbers are net carbs per 100 grams (3½ ounces).1
E.g. an average tomato has about 3 grams of carbs. A whole cauliflower head weighs perhaps ten times more, and may thus contain about ten times 4 grams, i.e. 40 grams of carbs.
Please note the difference between above-ground and below-ground vegetables.
Vegetables on keto
All foods are comprised of macronutrients – carbs, protein, and fat. While meat and most dairy are primarily made up of protein or fat, vegetables contain primarily carbs. On a strict ketogenic diet, with fewer than 5% of calories from carbs, it’s important to know which veggies are the lowest in carbs, particularly if your goal is to consume fewer than 20 grams of carbs per day.
Vegetables with less than 5 percent carbs may be eaten relatively freely on keto. If you’re on a not-too-strict low-carb diet (more than 20 grams per day), you can probably eat all you want of all these low-carb vegetables.
If you’re on a keto diet (below 20 grams a day), you may need to be a bit careful with some of the vegetables. You should be especially careful with peppers or tomatoes – these carbs quickly add up towards the 20 grams-a-day limit. Just one medium-sized pepper may contain 6-8 grams of digestible carbs.
More helpful guidelines
Here are two more general rules that can help you choose lower-carb vegetables:
- In general, keto friendly veggies are those with leaves — all types of lettuces, spinaches, etc. are good ketogenic options.
- Green vegetables tend to be lower in carbs than veggies with a lot of color. For example, green cabbage is lower in carbs than purple cabbage. Green bell peppers are also somewhat lower in carbs than red or yellow peppers.
Vegetables and fat
Use vegetables as a vehicle for fat by seasoning cooked vegetables with butter or ghee. Better yet, sauté or roast them in lard, coconut oil, avocado oil, or ghee. If you eat dairy, you can make a cream sauce with heavy cream, cheese, and/or cream cheese. Another excellent way to add fat to vegetables is by dipping them in salad dressings or other dipping sauces.

Vegetable sticks and dip
Vegetable sticks are relatively low carb and keto friendly, except for carrots that have slightly more carbs.
Dip: Add cream cheese or any really low-carb and high-fat dip sauce. Here are our top recipes:
Peas, corn, beans, lentils, quinoa
Peas, corn, beans, lentils and quinoa are not vegetables and contain more carbohydrates than vegetables. Be careful with them on a keto diet, eating them in very small amounts or not at all.
Most of these plant foods are not classified as vegetables but as grains or legumes. They are not good keto options.
Grains and pure sugar
Wheat is not a vegetable, it is a grain. And anything made with wheat flour contains lots of rapidly digested carbs. Avoid this as much as possible when on a keto diet. Whole-grain products are just less bad – it’s like cigarettes with filter.
Bread, pasta, rice, cookies etc. are not vegetables, and they are full of carbohydrates.
High fructose corn syrup – the sugary nutrient in soda – comes from plants (corn), but it is not a vegetable and it most certainly is not keto.
