A Quick Look at the Best Low Carb Protein Bars for Keto

The Atkins Snack Replacement Bars are some of the best-tasting keto bars out there, packed with about 190 calories per serving.

Keto Bars is a snack replacement bar that is specifically designed for a ketogenic diet. It has no added sugar and is completely free from gluten and nuts. It contains whey protein concentrate as its source of protein and coconut plus heavy cream as its source of fat.

Better Than Coffee Energy Bars are snack replacement bars designed to help you meet your macro-nutrition needs AND give you a boost of energy. This product does this thanks to its caffeine from Guarana and Maca plants.

The Mitomix Bar by Dr. Mercola is a snack replacement bar made for the ketogenic diet that contains MCT oil and organic ingredients.

InstaKetones Protein Bar by Julian Bakery aims to help with fat loss and boost endurance, mental clarity, and sustained energy. It does this by only using ingredients derived from grass-fed beef and healthy fats from coconut. Furthermore, this energy bar contains exogenous ketones in the form of beta-hydroxybutyrate to help you get into ketosis.

These low carb protein bars were developed to provide a tasty option for those on a low-carb diet. Aside from providing ample macronutrients, they are also a great source of such micronutrients as potassium, phosphorous, iron, magnesium, and calcium.

Oh Yeah! One Bars are snack bars designed for those on-the-go or those who need to bring snacks to the office or the gym. They contain whey protein isolate and milk protein isolate for its protein content.

Another product from Julian Bakery, the Primal Thin Protein Bar uses certified organic non-denatured protein from grass-fed beef. It is completely free of gluten, soy, and GMO ingredients.

Grenade Carb Killa is manufactured by the supplements giant GNC, and is designed to provide you with high amounts of protein with little net carbohydrates.

D’s Natural No Cow, as the name suggests, is a protein snack bar that does not contain any type of dairy and other animal product. It only contains natural ingredients while being high in protein (22 grams) and low in sugar (1 gram of sugars and 3 grams of net carbohydrates).

CarbRite Diet is a protein bar that is completely free of sugar. It provides 22 grams of protein, 4 grams of fat, and 22 grams of total carbohydrates (net carbs at 3 grams).


Reviews of the Best Low Carb Protein Bars for Keto


Each serving of this bar packs 5 grams of protein with 15 grams of fat, and 17 grams of total carbohydrates (2 grams of sugars and net carbs at 3 grams).

Atkins’ snack bar is great for those looking for a low-carb snack option but totally inadequate for those in search of a protein-packed snack.

coolimagecoolimagecoolimageAtkins Snack Bars, Dark Chocolate Almond Coconut Crunch

Additionally, it only has 11 grams of fat. In other words, if you’re on the ketogenic diet, this isn’t a meal replacement. It’s just a snack, so you need to look for more sources of dietary fat to have enough for your body’s energy needs.

Also, this product has no added sugar for flavoring and uses milk protein concentrate and soy protein isolate as its sources of protein.

Things We Liked

  • Satisfying taste
  • Filling to the appetite

Things We Didn't Like

  • Only 5 grams of protein
  • Artificially sweetened
coolimagecoolimagecoolimageKeto Bars

This one has 18 grams of fat with 7 grams of protein and 10 grams of total carbohydrates (1 gram of sugar and net carbs at 2 grams).

Since it contains a decent amount of fat, this one is a very good choice for those on keto. In addition to that, it gets its fat from real ingredients like coconut, butter, and heavy cream.

The Keto Bars do not contain any artificial sweeteners whatsoever, using only natural sources like Stevia and Erythritol.

Things We Liked

  • Real fat ingredients
  • No artificial sweeteners
  • No added sugars

Things We Didn't Like

  • Only contains whey concentrate
  • On the lower end in protein content
  • No option for those with nut allergies or lactose intolerance

Like the Atkins bar, we don’t see this snack bar as suitable for those on the ketogenic diet. This is more of a healthy energy-boosting snack before a workout or during the middle of the day in the office.

It contains 6 grams of fat, 5 grams of protein, and 12 grams of total carbohydrates (3 grams of sugars and net carbs at 8 grams). At the same time, it is gluten-free and contains no dairy, soy, nuts, or other animal products. It gets its protein from pea protein concentrate.

coolimagecoolimagecoolimageBetter Than Coffee Energy Bars

Things We Liked

  • Good energy boost
  • Suitable for vegans
  • Suitable for those with nut allergies

Things We Didn't Like

  • High caffeine content
  • Only 5 grams of protein
  • Low fat content
coolimagecoolimagecoolimageDr. Mercola Mitomix Bars

Mitomix bars are good low-carbohydrate and high-fat snack bars. However, they don't have enough protein to completely fuel your needs after a workout or even between meals.

Aside from MCT oil as a source of fat, it also uses a mix of organic nuts like macadamia, almonds, cacao nibs, pumpkin seeds, and chia seeds.

It contains 11 grams of fat, 3 grams of protein, and 21 grams of total carbohydrates (4 grams of sugars and net carbs at 4.9 grams). It only contains natural sweeteners like erythritol, inulin, and stevia.

Things We Liked

  • MCT content
  • Natural ingredients
  • Decent amount of fat content

Things We Didn't Like

  • Low protein
  • Unpleasant taste

This protein bar got all that you’d need from a protein and low-carb bar. It even has exogenous ketone bodies so you can reach ketosis before your workout.

Each bar contains 8 grams of fat, 15 grams of protein, and 18 grams of total carbohydrates (no sugars and net carbs at 4 grams).

coolimagecoolimagecoolimageInstaKetones Protein Bar

The only problem we have with InstaKetones is that snack bars should taste good. For this one, you would really have to work hard to get it down your stomach. Nevertheless, once you’re able to eat it, you’d find that it really works.

Things We Liked

  • Exogenous ketones
  • MCT oil
  • Good amount of protein

Things We Didn't Like

  • Tastes really bad
  • Not really a snack bar (due to the taste)
coolimagecoolimagecoolimageQuest Nutrition Protein Bar

On paper, the Quest bar is a good low-carbohydrate snack. In reality, however, there’s nothing good about the taste and it caused some of us a stomach upset.

It contains 8 grams of fat, 21 grams of protein and 21 grams of total carbohydrates (1 grams of sugars and net carbs at 4 grams).

Things We Liked

  • Low Carbohydrate content
  • Contains whey protein isolates
  • Soy-free

Things We Didn't Like

  • Artificial Sweeteners
  • Can cause upset stomach
  • Really bad taste

Oh Yeah! One is a decent protein bar. But, it does not have enough fat content to make it a truly great snack for a ketogenic diet.

One serving contains 21 grams of protein, 9 grams of fat, and 22 grams of total carbohydrates (1 gram of sugars and net carbs at 3 grams).

coolimagecoolimagecoolimageOh Yeah! One Bars

Things We Liked

  • Protein Isolates
  • Good protein content

Things We Didn't Like

  • Bad aftertaste
  • Low fat content
coolimagecoolimagecoolimagePrimal Thin Protein Bars

This paleo protein powder bar contains all 9 essential amino acids with 3 branched-chain amino acids. For macronutrient content, one serving contains 5 grams of fat, 20 grams of protein, and 19 grams of fat (1 gram of sugars and net carbs at 1 gram).

The fact that it only uses organic ingredients is a great bonus as well. But, like the One protein bar, it does not have enough fat to provide energy during a keto diet.

Things We Liked

  • Decent amino acid content
  • High protein content
  • Organic ingredients

Things We Didn't Like

  • Low fat content
  • Bad taste

Similar to Primal Thin and Oh Yeah, it provides a good amount of protein but not enough fat to provide energy while on keto. It contains 8 grams of fat, 22 grams of protein, and 21 grams of carbohydrates (net carbs at 2 grams).

It uses milk protein in the form of Calcium Caseinate, Whey Protein Isolate, and Milk Protein Isolate. It does not contain any artificial flavors.

coolimagecoolimagecoolimageGrenade Carb Killa

Things We Liked

  • High in protein
  • Low net carbs
  • Good mix of protein ingredients

Things We Didn't Like

  • Low fat content
  • Artificial sweeteners and flavors
coolimagecoolimagecoolimageD’s Natural No Cow

This a good protein bar like the last three products on this list. And, just like some others, it also falls short in fat content for keto.

It gets its protein from a blend of brown rice protein and pea proteins and uses stevia and erythritol to get its sweet flavor. This  product is available in various flavors from banana bread to peanut butter and fudge brownie.

Things We Liked

  • High protein content
  • Good vegan option
  • Natural flavors and sweeteners

Things We Didn't Like

  • Low fat content
  • No nut-free option

This is a high-protein bar but it has too little fat to provide energy on  keto. Moreover, there have been some complaints regarding inconsistent product quality.

This product is free of gluten and hydrogenated oil or trans-fats. For protein, it uses soy protein isolate and whey protein isolate.

coolimagecoolimagecoolimageUniversal Nutrition Doctor’s CarbRite Diet

Things We Liked

  • High protein content
  • Low net carbs
  • Gluten and trans-fat free

Things We Didn't Like

  • Low fat content
  • Soy ingredients

If you’re following a targeted ketogenic diet to maximize muscle growth and enhance performance, it is crucial that you avoid protein bars with any amount of fructose content.

By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

Things to Look for Low Carb Protein Bars

The Carbohydrate Content

Since you’re aiming to stay on ketosis, controlling your carbohydrate intake is the most crucial element for success. Essentially, you would want a protein bar that would let you stay within your daily maximum carbohydrate intake.

If you’re taking a ketogenic diet with fat loss in mind, make sure that your carbohydrate intake stays within the limits of 15 percent of the total daily caloric intake. Furthermore, if you’re a following targeted ketogenic diet to maximize muscle growth and enhance performance, it is crucial that you avoid protein bars with any amount of fructose content.

The Protein Source

Since you’re looking for a protein bar for your keto diet, you would want one that contains at least 25% of fat out of its total product serving. Moreover, you would want medium-chain triglycerides in the ingredients as this type of fatty acid can easily be converted by the body into ketone bodies.

Look for protein bars with whole dairy ingredients like whole milk, butter, and cheese. Coconut oil and kernel oil are particularly good sources of fat. Avoid anything that is fat-free or skimmed dairy as these barely contain medium-chain triglycerides.

The Fiber Content

Fiber slows down the breakdown of carbohydrates to glucose. Additionally, this prevents rapid fluctuations in your blood sugar levels which could put your body out of ketosis.

This is why a decent low-carbohydrate protein bar always has dietary fibers to prevent it from happening. There will always be carbohydrates in these protein bars so the next best thing is to have fiber to slow its absorption.

The Verdict

To choose our winner for this product round up, we have to consider that it should provide a good amount of protein while giving good caloric content from fat. And, after going through the best low-carb protein bars for keto, we can’t help but choose 2 winners.

The first is the InstaKetones Protein Bar. Even though the taste is not that great, we still recommend this product as a convenient all-in-one keto snack. You get exogenous ketone bodies, medium-chain triglycerides, and a good amount of protein from lactose-free sources. Furthermore, some product reviews suggest that one would eventually get used to the taste.

The second is Keto Bars. Although it provides only 7 grams of protein, it is still a very good keto snack bar. Specifically, it's almost the perfect keto snack when you’re on the go, completely natural and having whole 18 grams of fat content.

If you want great-tasting beverage to go with your choice in the best low carb protein bars for keto, you might want to try keto coffee with low carb coffee creamers as well.
