Most of us love carbs—pasta, bread, grains, all those good things—but often, carbs just don’t love us back. A low-carb diet can actually be a good way to keep your health in check (blood glucose and insulin levels decrease, which minimizes fat storage in your body), but 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 easy tricks (more on that in a bit). First of all, carbohydrates are a macronutrient food group that is used for energy in the body.

Don’t forget that our body needs carbs to carry out its processes, but when we consume too many carbs, the body starts to store fat.

“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, MS, RD, CDN, 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.

(Just be mindful that these carbs should not take up more than a quarter of your plate at each meal.)

Now, 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. One thing Shalek says she’s strict about with her clients—including vegetarians—is not completely eliminating carbs from their 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.” Now, in case you’re wondering which foods you should be consuming more of on a low-carb vegetarian diet, we asked Shalek to share her 15 favorites below, plus one day’s worth of go-to meals that incorporate them.

Almonds

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

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

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

Nonfat Greek Yogurt

Other than being rich in protein and calcium, nonfat 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

Green Leafy 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

Eggplant

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 since it’s plenty filling.

Carbohydrates: 5 grams per 1/2 cup

Eggs

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 that 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 one gram per egg

Tofu

“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

Tempeh

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. (FYI, it’s basically tofu in cake form.)

Carbohydrates: about 8 grams per 1/2 cup

Berries

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

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

Avocado

If you’re into avocados, here’s the good news: They contain healthy fats that are high in 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 with this treat: 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.”

Carbohydrates: 0
