As much as we love carbs—pasta, bread, grains, all those good things—carbs don’t always love us back. Experts say a low-carb diet can actually be a good way to keep your health in check and maintain a healthy lifestyle, but for those with meat-free dietary preferences and restrictions, what about trying to follow a low-carb vegetarian diet? It’s a bit more of a challenge, but it’s definitely doable with some guidance. Here’s how to follow a low-carb diet as a vegetarian.

What is a Low-Carb Diet?

A low-carb diet is a popular tool used for weight loss and management. Low carb diets are usually followed to help you lose weight. How Well, when you cut carbs out of your daily diet, it helps reduce your insulin and blood glucose levels—and that helps you to stop storing fat in your body.

The Benefits of a Low Carb Diet

“The good news is that a low-carb diet does not involve calorie-counting, a method which tends to make people feel deprived,” says Juliana Shalek, M.S., R.D., C.D.N., and founder of The Nutrition Suite LLC. “On a low-carb diet, you can still fill up on protein and healthy fats, which can be very satisfying,” Shalek explains, adding that you can still have carbs that are high in fiber with a lower glycemic index—like oatmeal, beans, and whole-grain bread—since they have less of a significant impact on our glucose levels.

Danielle Zies, CNP, Certified + Registered Holistic Nutritionist, says "A low-carb diet can be beneficial for helping to get blood sugar levels under control. When your blood sugar levels are more stable, your energy gets better, you sleep better and you feel better. It's foundational support for your body on so many level, including healthy skin, hormones and organs function. Less cravings and weight benefits come as a result of getting your blood sugar under control."

Safety Considerations

To be clear, our body needs carbs to carry out its processes, but when we consume too many carbs, the body starts to store it as fat. Carbohydrates, like protein, and fat, are macronutrients, which the body uses for energy.

If you are following a low-carb vegetarian diet, Shalek says you should continuously monitor your protein levels since you won’t be getting certain nutrients from meat. But other than that, you’re good to go. Shalek strongly recommends against completely eliminating carbs from your diet. “Carbs serve an important role in our body, and if we completely cut them out, we are more likely to overeat them later,” Shalek explains. “So I urge mindfulness: Choosing whole grains instead of refined carbohydrates, watching portion sizes, and trying to spread out servings of carbohydrates evenly and consistently over the course of the day to promote better blood glucose control.”

Zies adds, "Keep in mind that any plant (fruit, veggie, legume, grain, nut, seed, etc) is a carbohydrate to a degree (with a few exclusions such as coconut and avocado). Sometimes, cutting carbs too low can lead to deficiencies and imbalances. People can notice symptoms such as hair thinning, nail breakage, brain fog, fatigue, weakness, hormonal imbalances and more."

As a macronutrient, carbs serve an important role in our body, and if we completely cut them out, we are more likely to overeat them later.

Low-Carb Dairy Products

Non-Fat Greek Yogurt

Other than being rich in protein and calcium, non-fat Greek yogurt also contains probiotics to aid in digestive health. “It’s so versatile—you can add to fresh fruit or low-fat granola or use it as a lower-fat substitute for mayonnaise or sour cream in certain dishes,” explains Shalek.

Carbohydrates: 9 grams per cup

Low Fat Cheese

The Laughing Cow cheese packets are low in fat and calories but are still satisfying (and did we mention they also provide a punch of calcium?) “They come in various flavors that you can spread on fruit, vegetables, or rice cakes,” says Shalek. “Plus, they come in cute little wedges that are portable.”

Carbohydrates: About one gram per cheese wedge

Cottage Cheese

“You can add fruit and nuts or blend in a smoothie for added protein for breakfast or a snack,” says Shalek. In case you didn’t know, cottage cheese is an excellent source of protein, calcium, and vitamin B12 (just opt for a low-fat version if possible.)

 Carbohydrates: 6 grams per 1/2 cup

Other Low-Carb Vegetarian Foods

This nut is a good choice because it’s high in protein, fiber, and heart-healthy fat. Furthermore, Shalek says almonds are a great snack on-the-go (just try to choose unsalted). However, “It’s important to be mindful of serving size since they are high in fat”, she notes.

Carbohydrates: 7 grams per 1/4 cup

Chia Seeds

Chia seeds can be used as a high-protein and high-fiber topping in your salads, smoothies, yogurt, and cottage cheese. “Plus, they’re high in omega-3 fatty acids, which help reduce inflammation in the body and lower your risk of cardiovascular disease,” explains Shalek. Worth noting: They contain about five grams of fiber per tablespoon, so technically your net carbs are low per serving.

Carbohydrates: 5 grams per tablespoon


Chickpeas (aka, what hummus is made from) are somewhat high in carbs but are also high in fiber. “These happen to be a good protein source for vegetarians,” says Shalek. “If you are mindful of portion size, chickpeas are the perfect addition to any meal in whole or puréed form.”

Carbohydrates: About 27 grams per 1/2 cup

Leafy Green Vegetables

“Non-starchy vegetables such as kale and spinach are what I like to call ‘good bang for your buck’ foods,” says Shalek. “This means you can fill up on them without taking in an abundance of calories, and they’re high in fiber so they keep you full between meals.” Additionally, these veggies contain important vitamins like C, A, and K, plus iron.

Carbohydrates: Less than one gram per 1/2 cup


This tasty vegetable contains a variety of vitamins and minerals like folate, potassium, and vitamins C and K (plus, a lot of fiber). Use it in place of meat for your main course since it’s plenty filling.

Carbohydrates: 5 grams per 1/2 cup


Eggs are great for a low-carb vegetarian diet because they are protein-rich and contain healthy fats (and keep you full longer due to their high protein). Bonus points: They’re easy to prepare and you can avoid monotony by cooking them different ways, says Shalek. “You can remove the yolk if you’re watching cholesterol levels,” she says.

Carbohydrates: Less than 1 gram per egg

“Tofu is a great source of protein for non-meat eaters, and it’s so versatile that it can be used in various dishes,” says Shalek. It’s low in calories and fat and high in iron and calcium.

Carbohydrates: 5 grams per cup


Like tofu, tempeh is also a good source of protein for non-meat eaters, and it’s just as versatile, says Shalek. Plus, it contains probiotics.

Carbohydrates: About 8 grams per 1/2 cup

Berries are high in fiber, antioxidants, vitamin C, and folate, which all have a beneficial impact on your body. “Do be mindful of appropriate portion sizes because they contain sugar—although they are also high in fiber to prevent significant sugar spikes and to keep you full longer,” says Shalek.

Carbohydrates: About 11 grams per 1/2 cup


If you’re into avocados, here’s the good news: They contain healthy fats rich with monounsaturated fatty acids and important nutrients, including folate, vitamins C and K, and potassium. They’re high in fiber, keep you full, and help regulate blood glucose levels. “Eat them on their own, as a spread, or as a dip,” suggests Shalek.

Carbohydrates: About 9 grams per 1/2 avocado 

Nut Butter

A little goes a long way: Spread it on an apple, a piece of celery, a whole-grain cracker, or eat it on its own. “It’s a very satisfying snack to keep you full between meals since it’s so high in protein,” says Shalek.

Carbohydrates: 3 grams per tablespoon

Olive Oil

So it’s not quite a food per se, but olive oil is certainly low in carbs and has many beneficial health properties (it actually contains zero carbs.) “It’s rich in monounsaturated fatty acids, which help reduce inflammation and protect against cardiovascular disease,” says Shalek. “It’s great for cooking and for salad dressings. Just stick to the serving size of one tablespoon to avoid too many additional calories.”

The Takeaway

Low-carb vegetarian diets can be a bit hard to follow, but they don't always have to be. Zies says, "For vegetarians, it can be more difficult to achieve a low-carb diet (and often easy to go the opposite way towards a high-carb diet). My recommendation for vegetarians is to take a more "mindful" carb approach where you opt for more slow burning carbohydrates such as starchy veggies (squash, beets, carrots, potatoes, yams, etc), whole grains and legumes over refined carbs and simple sugars that are easy to overeat and can keep us riding the ups and downs of the roller coaster imbalanced blood sugar levels can cause. This will ensure you keep your nutritional baselines covered in a healthy way, which is the ultimate goal."
