The ketogenic, or keto, diet is a very low carb, high fat diet that’s associated with several health benefits, including weight loss (1).

For those following this diet, protein bars can be a convenient, grab-and-go option when you need a quick meal or filling snack. However, finding a keto-friendly bar can be difficult, as most protein bars are either too high in carbs, too low in fat, or contain ingredients that don’t fit on a keto diet, like dairy.

Plus, even protein bars that meet the right criteria aren’t always healthy options, as they often contain large amounts of artificial ingredients, additives, and preservatives.

Still, if you look carefully, you can find protein bars that are both keto-friendly and nutritious. Alternatively, you can make them on your own.

What are net carbs?

Keto-friendly bars like the ones on this list regularly contain fiber and sugar alcohols, which your body can’t fully digest and absorb. Therefore, subtracting the grams of fiber and sugar alcohols from the total carbs gives you the number of net (digestible) carbs.

You’ll often see the number of net carbs highlighted on the packaging — though this value is likely lower than the number of total carbs listed among the nutritional information.

When choosing the best keto protein bars, we considered the following factors:

  • Ingredient quality. Ideally, the bar should be made predominantly with whole foods and without added sugar, artificial colors or flavors, or unnecessary fillers.
  • Taste. A keto protein bar should be flavorful and not taste like a block of cardboard. We looked for brands that offer intriguing flavors with positive reviews.
  • Nutrition. The bars on this list provide 5 grams of net carbs or fewer per serving. They also contain a minimum of 6 grams of protein and at least 7 grams of fat.
  • Price. These bars are typically sold in multipacks and most cost between $25–$50 per multipack.
  • Customer reviews. We’ve read through reviews to find out how customers feel about the flavor, texture, and quality of these bars.
  • Vetting. The protein bars on our list have been vetted to ensure that they align with Healthline’s brand integrity standards and approach to well-being. You can read more about our vetting process.

Perfect Keto Bars

Price: $$

Specifically formulated for the keto diet, these protein bars come in six flavors, including Peanut Butter Chocolate Chip, Banana Bread, Cinnamon Roll, Chocolate Chip Cookie Dough, Salted Caramel, and Almond Butter Brownie.

Perfect Keto bars have a relatively short ingredient list based on predominantly whole foods. The Peanut Butter Chocolate Chip flavor contains peanut butter, grass-fed collagen, allulose (a type of sugar that resembles fructose found naturally in fruit), 100% cacao chips, peanuts, cocoa butter, medium-chain triglycerides (MCT) oil powder, sunflower lecithin, MCT oil, sea salt, stevia extract, and monk fruit extract.

They contain no added sugar, sugar alcohols, additives, or fillers.

While more research is needed, the fatty acids found in MCT oil may improve exercise performance and promote weight loss by decreasing energy intake (2, 3).

Here’s the nutrition info for the Peanut Butter Chocolate Chip flavor:

  • Calories: 240
  • Protein: 13 grams
  • Fat: 18 grams

Best high protein

MariGold Protein Bars

Price: $$

There are 12 different flavors of MariGold protein bars included in a Very Low Keto 12-pack.

The flavors include Almond Mocha Crunch, Coconut Rage, Ginger Coconut, Macarooned, Chocolate Mint, Salty Caramel, Pure Joy, Banana Nut, Double Fudge Brownie, ChunkyChoco Pecan, Dark & Salty, and Cinnabähn.

These bars are made with just a few ingredients, which include whey isolate from grass-fed cows milk, cashews, filtered water, chicory root fiber, L-glutamine, grass-fed ghee, organic flavors, coconut oil, stevia extract, salt, and sunflower lecithin.

Whey protein is a popular supplement because its protein can be quickly absorbed by your body. As a result, it may promote significant increases in strength, muscle mass, and even fat loss (4, 5, 6, 7).

MariGold bars are also free of sugar alcohols, which are natural or manufactured carbs that taste sweet yet contain half the number of calories as sugar. Some people may wish to avoid sugar alcohols because they can sometimes cause digestive distress (8).

Instead, they are sweetened with stevia, although a few of the bars also contain very small amounts of coconut nectar, coconut sugar, or maple syrup.

Additionally, some MariGold bars are low in short-chain, undigestible carbs called FODMAPs, which may cause digestive side effects like bloating, gas, and constipation in some people, particularly those with a diagnosis of irritable bowel syndrome (IBS) (9).

Here’s the nutrition info for the Salty Caramel flavor:

  • Calories: 226
  • Protein: 22 grams
  • Fat: 12 grams
  • Net carbs: 5 grams
  • Fiber: 6 grams


  • high protein content
  • wide variety of flavors


  • some reviewers find the stevia flavor to be a little too strong

Best meat-based


Price: $$

EPIC bars are meat-based bars that come in four flavors, including Sea Salt & Pepper Venison, Jalapeno Beef, Sea Salt & Pepper Beef, and Sriracha Chicken.

They contain only a handful of keto-friendly ingredients.

For instance, the Sea Salt & Pepper Venison EPIC bar is made using grass-fed venison, sea salt, encapsulated lactic acid (not from milk), water, black pepper, cultured celery powder, onion powder, and garlic powder.

While these bars are low in net carbs, they’re very high in sodium, providing between 600–750 mg of sodium per bar, depending on the flavor. The majority of other bars on this list only contain 100–200 mg of sodium each.

Here’s the nutrition info for the Sea Salt & Pepper Venison flavor:

  • Calories:150
  • Protein:13 grams
  • Fat:10 grams
  • Net carbs:0 grams
  • Fiber: 1 gram


  • very low in net carbs
  • minimal ingredient list


  • high in sodium
  • not suitable for plant-based diets

Keto Bars

Price: $$

Founded in 2012, Keto Bars was one of the first companies to create protein bars specifically for the keto diet. In addition to being high in fat and low in net carbs, their bars are vegan, dairy-free, gluten-free, and soy-free.

All four of their flavors have short ingredient lists and are made with a base of unsweetened chocolate, coconut, and nut butter.

To keep them sugar-free, Keto Bars use two alternative sweeteners — stevia and erythritol — in place of added sugar.

Erythritol is a sugar alcohol that occurs naturally in some fruits like watermelon and grapes, as well as fermented foods like cheese and wine. However, it can also be manufactured (10).

Although erythritol appears to be very safe, large doses can cause digestive issues like bloating, abdominal pain, gas, and diarrhea (8, 10).

As one Keto Bar contains just 5 grams of this sweetener, it’s highly unlikely to result in these side effects.

The Mint Chocolate bar contains chocolate, almonds, coconut, non-GMO erythritol, cocoa processed with alkali, water, salt, stevia, and peppermint oil.

Here’s the nutrition info for the Mint Chocolate flavor:

  • Calories: 240
  • Protein: 6 grams
  • Fat: 20 grams
  • Net carbs: 4 grams
  • Fiber: 6 grams


  • vegan
  • allergen-friendly


  • erythritol could cause digestive side effects for some people
  • lower protein

Best organic

BHU Keto Bars

Price: $$

BHU’s keto-friendly protein bars have a fudgy texture and are made without any artificial sweeteners or preservatives. As a result, they need to be kept refrigerated.

All BHU Foods keto bars are USDA organic and Non-GMO Project verified.

These bars come in eight flavors, including Chocolate Chip Cookie Dough, Peanut Butter Chocolate Chip Cookie Dough, White Chocolate Macadamia Cookie Dough, Double Dark Chocolate Cookie Dough, Chocolate Coconut Cookie Dough, Snickerdoodle Cookie Dough, Caramel Peanut Chocolate Chip Cookie Dough, and Mint Double Dark Chocolate Cookie Dough.

One unique ingredient in these bars is organic tapioca flour, which contains prebiotic fiber.

This indigestible fiber helps feed beneficial bacteria in your gut, supporting proper digestion, a strong immune system, and heart health (11, 12).

The ingredients in a white chocolate macadamia cookie dough bar include cashews, white chocolate, red palm oil, tapioca fiber, pea protein, macadamia nuts, MCT oil, baobab, vanilla, sunflower lecithin, sea salt, monk fruit, and water.

Here’s the nutrition info for the White Chocolate Macadamia Cookie Dough flavor:

  • Calories: 250
  • Protein: 11 grams
  • Fat: 20 grams
  • Net carbs: 0 grams
  • Fiber: 11 grams

Best vegan

Dang Bars

Price: $$

Dang bars are vegan and keto-friendly. They come in five flavors, including Lemon Matcha, Toasted Coconut, Crazy Rich Chocolate, Almond Cookie, and Peanut Butter.

Many of the ingredients in Dang bars are instantly recognizable as nutritious and keto-friendly, such as nuts, pea protein, and chia and sunflower seeds.

For example, the ingredients in a Lemon Matcha Dang bar include almonds, chicory root fiber, cocoa butter, pea protein, sunflower seeds, coconut, chia seeds, natural flavors, lemon oil, sunflower lecithin, matcha green tea, citric acid, sea salt, stevia extract, and mixed tocopherols.

Plus, these bars contain chicory root fiber, which is an excellent source of gut-healthy prebiotic fiber. That said, it’s also high in short-chain carbohydrates called FODMAPs, so individuals with digestive conditions like irritable bowel syndrome (IBS) may not tolerate these bars particularly well (13, 14).

Here’s the nutrition info for the Lemon Matcha flavor:

  • Calories: 210
  • Protein: 9 grams
  • Fat: 15 grams
  • Net carbs: 5 grams
  • Fiber: 6 grams


  • vegan
  • contain prebiotic fiber


  • contain FODMAPs

Best with collagen

Bulletproof Collagen Protein Bars

Price: $$

Bulletproof bars are dairy-free, gluten-free, and non-GMO. They recently changed their formulation resulting in bars with a new soft, cookie-like texture and less oiliness.

Bulletproof collagen protein bars come in four flavors, including Chocolate Chip Cookie Dough, Vanilla Shortbread, Fudge Brownie, and Lemon Cookie.

These bars are made using grass-fed easily digestible hydrolyzed collagen, which may help support healthy skin, bones, and joints in addition to providing protein (15, 16).

They also contain inulin, a prebiotic fiber found in plant roots that helps feed beneficial gut bacteria. Inulin has been found to improve digestive health and bowel regularity (17, 18).

The Vanilla Shortbread flavor contains cashew butter, hydrolyzed collagen, inulin, MCT oil powder, cashew meal, sunflower lecithin, safflower or sunflower oil, sea salt, ground vanilla beans, organic stevia leaf extract, natural flavors, and vanilla extract.

Here’s the nutrition info for the Vanilla Shortbread flavor:

  • Calories: 190
  • Protein: 11 grams
  • Fat: 12 grams

Best high fiber

No Cow Dipped Bars

Price: $$

No Cow Dipped Protein Bars are vegan and keto-friendly bars made using all plant-based ingredients. They’re also certified gluten-free and kosher, soy-free, and Non-GMO Project verified.

These are a chocolate-dipped version of the No Cow regular protein bars, and with 11–15 grams of fiber per bar, they contain the most fiber out of all of the bars on our list. Consuming adequate fiber each day is associated with a number of health benefits (11, 12).

They come in six flavors, including Chocolate Sprinkled Donut, Chocolate Sea Salt, Chocolate Peanut Butter Cup, Chocolate Salted Caramel, Chocolate Mint Cookie, and Chocolate Coconut Almond.

The Chocolate Sea Salt bar is made using a brown rice and pea protein blend, soluble corn fiber, chocolate coating, glycerine, almonds, palm oil, natural flavors, cocoa powder, salt, water, and a sweetener blend of monk fruit, stevia extract, and erythritol.

Note that while erythritol is a sugar alcohol that is generally considered very safe, consuming it in large amounts may cause digestive side effects like nausea and stomach discomfort (8, 10).

Here’s the nutrition info for the Chocolate Sea Salt flavor:

  • Calories: 200
  • Protein: 20 grams
  • Fat: 7 grams
  • Net carbs: 3 grams

Homemade keto bars are ideal if you want to carefully control the ingredients used or simply enjoy the craft of concocting your own foods.

This recipe makes bars with 319 calories and 7 grams of protein each. Furthermore, each bar provides a whopping 28 grams of fat and only 4 grams of net carbs.

In addition to a handful of other whole ingredients, these bars are rich in almonds, pecans, and almond butter. Research has shown that regular nut intake may aid weight loss and benefit heart health (19, 20).

Anyone who loves peanut butter cups will enjoy these no-bake peanut butter protein bars that take fewer than 10 minutes to make.

All you need are five low carb ingredients — coconut flour, a protein powder of your choice, peanut butter, a sticky sweetener of your choice, and chocolate chips.

To keep these bars keto-compliant, the recipe recommends using monk fruit syrup because it’s carb-free. You may want to double-check that both your protein powder and chocolate chips are keto-friendly as well.

There are several versions of the keto diet, though the most popular one encourages you to get at least 70% of your daily calories from fat, 20% from protein, and no more than 10% from carbs (1).

Thus, you’ll want to stick to this macronutrient breakdown as closely as possible when choosing a keto protein bar (1, 21).

For a 200-calorie bar, this ratio would equal 16 grams of fat, 10 grams of protein, and no more than 5 grams of carbs.

Try to avoid bars with a long list of ingredients you don’t recognize, such as artificial sweeteners or preservatives, as these indicate that the bar is heavily processed.

Diets high in ultra-processed foods are linked to an increased risk of chronic illnesses, such as cancer, heart disease, and obesity (22, 23, 24).

Instead, choose bars made mostly from real foods, such as oils, spices, natural sweeteners, nuts, and seeds. As the keto diet is high in fat, you should also look for healthy fats like nuts and nut butter, MCT oil, avocado oil, and flax, chia, or hemp seeds.

A keto diet, which is based on very low carb and high fat foods, has been shown to offer a number of potential benefits when combined with sound nutrition principles.

Originally created for the management of childhood epileptic seizures, the keto diet has become popular with the general public for a number of health reasons (25).

One of these is that it may help promote weight loss, at least while the diet is being followed (26).

Some research has also found that a keto diet can be beneficial for improving blood sugar management (27, 28, 29).

Furthermore, some studies suggest that it may also support brain health, possibly offering a therapeutic benefit for diseases like Alzheimer’s and Parkinson’s (30, 31).

That said, more research is needed on the long-term health effects of following a keto diet.

Can you have Atkins bars on the keto diet?

Most Atkins bars will fit on a keto diet, as they generally contain a low amount of net carbs and are sweetened with sugar alcohols in place of added sugar. It’s always best to read the ingredient list to make sure any protein bar aligns with your needs and preferences.

Are low carb protein bars good for you?

Low carb protein bars can be a convenient and quick way to boost your protein intake if you don’t have time to make a protein-rich, keto-friendly snack. However, not all are created equal.

We recommend reading the nutrition facts and ingredient list on any low carb protein bar you’re considering and seeing how it compares with the options listed above. Ideally, bars will have ingredients derived from whole foods, a short ingredient list, and no added sugar or unnecessary fillers.

Are Fiber One bars keto?

Fiber One bars are not the best snack bars to eat on a keto diet. This is because they generally are lower calorie, lower fat, and contain around 12–20 grams of net carbs, which is more likely to break ketosis.

Fiber One bars also don’t contain much fat, with most varieties only providing around 6 grams per bar. As a keto diet is characterized by very low carb, high fat foods, Fiber One bars don’t meet most of these requirements.

Numerous low carb, high fat protein bars align with the keto diet to keep you full between meals or provide a quick and easy breakfast.

It’s important to look for ones that pack a decent amount of protein, fiber, healthy fats, and other nutritious ingredients.

Of course, whipping up a batch of homemade bars is a great option as well.
