The 18 Best Low-Carb Vegetables | Popular, Versatile, and Easy to Cook and Integrate in Most Diets

Low-Carb Vegetables...as long as you eat vegetables!

Low-Carb Vegetables are a hot topic right now, however, no matter the diet one follows, it is always a good idea to include more vegetables, as these can be low in calories, yet extremely rich in nutrients, vitamins, and minerals; there are plenty of low-carbohydrate vegetables that are rich in fiber and extremely versatile, making them very easy to add to most diets.

The definition of a low-carb diet varies vastly depending on who and how is following it, however, as a general rule, diets that include less than 150g of carbohydrates each day are considered low-carb; some diets go even as low as 20g of carbs per day.

Find below a list of the tastiest low-carbohydrate vegetables which are extremely versatile and therefore easy to add to most recipes.

Conclusions on Low-Carb Vegetables

Although this list may not contain all of the low-carb vegetables, the ones I have included are those I feel are the most versatile and easy to add to most diets; some can be eaten both raw or cooked and most can be easily chopped and added to a stew, sauce or curry to bulk up without adding too many carbohydrates.

While these vegetables (and a couple of fruits eaten as vegetables) are low in carbohydrates, most of them are also low in calories and rich in nutrients, such as minerals and Vitamins.

If you like very few vegetables, try cooking them in different ways to ensure you don’t get bored! As an example, carrots can be added to a beef stew, grated in a salad, julienned to use as a dipping stick, added to soups, or also roasted and served as a side dish (whit a bit of butter, perhaps?)

No matter what diet you are following, remember to ‘eat the rainbow’ as different colored vegetables, will have different nutrients, minerals, Vitamins, and benefits.
