Keto vegetables – the best and the worst

What vegetables are good on a keto diet? There’s a very simple rule:

  • Vegetables growing above ground are low carb and can be eaten freely.
  • 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.

Above ground

All numbers are net carbs per 100 grams (3½ ounces).1

Below ground

Keto vegetables growing below ground

All numbers represent percent of net carbohydrates.2 This means that a hundred grams (3½ ounces) – the weight of an average tomato – of any vegetable will contain this number of grams of carbs.

E.g. an average tomato has about 3 grams of carbs. A whole cauliflower head weighs a lot more though, 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 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 probably 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.

Vegetable sticks and dip

Low-carb snacks: vegetable sticks


Numbers are digestible carbs per 100 grams (3½ ounces).

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

Carbohydrates in 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

Grains, sugar, starches.

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.
