27 Best Keto Vegetables to Balance All That Meat and Cheese

Low-Carb Vegetables

Americans continue to struggle with overweight and obesity. Several diet regimens, like intermittent fasting or macros, are promoted for weight loss. Another diet, the ketogenic diet, is arguably one of the most popular diets. 

The keto diet limits carbohydrates and the majority of calories come from fat and protein. It is common to do daily carb counts and limit intake to 50 grams of carbohydrate per day or less.

Due to the very limited amount of carbohydrates allowed on a ketogenic diet, entire groups of food are restricted, including grains, breads, cereals, dairy, and fruit. These groups of food are important sources of needed nutrients such as fiber, vitamins, and minerals. Eating vegetables is important to make sure that you within your carb count but are still getting those needed nutrients.

For example, vitamin C is an essential nutrient that is particularly important in supporting immune health. Citrus fruits, kiwi, and strawberries are all great sources of vitamin C but would likely provide more carbohydrate than allowed on a ketogenic diet. However, bell pepper is also a rich source of vitamin C and it provides very little carbohydrates.

Is there such a thing as a keto vegetable? Below are 23 keto-friendly vegetables to include in your meal plan.
