Best Protein Bars for Diabetics (2024): Raise Your Protein, Not Your Blood Sugar 

Balancing carbs, protein, and fat is essential for regulating blood sugar in people with diabetes. Protein bars offer a convenient way to increase protein intake, which helps slow sugar absorption and minimize blood sugar spikes. However, not all protein bars are made for diabetes management. Choosing bars that are high in fiber and low in sugar can help maintain stable blood sugar levels. To simplify your search, we’ve narrowed down the best protein bars for diabetics. 

As a registered dietitian, I’ll break down the ingredients in each bar to help you understand their impact on diabetes. Additionally, our GGR testers, including certified personal trainers, professional athletes, marathoners, and nutrition experts, offer their honest insights regarding the taste, texture, and cost of each protein bar so you know exactly what to expect.

When looking for the best protein bar for diabetics you want to find an option that’s high in fiber and protein, and low in sugar. Perfect Keto Collagen Protein Bars check all the boxes. They’re made from real food and don’t contain sugar, artificial sweeteners, or corn syrup like many other protein bars on the market. 

These bars are available in five different flavors on Amazon, including Almond Butter Brownie, Chocolate Chip, Cinnamon Roll, Peanut Butter, and Salted Caramel. They all contain between 10 and 12 grams of collagen protein per bar, offering a convenient way to boost protein intake. 

RELATED: How To Get More Protein

Unlike whey protein, collagen protein doesn’t contain lactose, a type of sugar in dairy products that can raise blood sugar levels. Collagen protein supports skin, hair, nails, bone, and joint health. Protein digests slower than carbs and helps reduce the rate of sugar absorption into the bloodstream. 

Perfect Keto Collagen Protein Bars are also high in fiber, with most flavors containing 8 to 9 grams. Thanks to this fiber content, most flavors—except for Peanut Butter—have only 2 to 3 grams of net carbs, the carbs that affect blood sugar. Fiber slows the digestion of carbohydrates, which helps regulate the release of glucose into the bloodstream.

We love that these bars don’t contain any added sugar. Instead, they’re sweetened with stevia extract, a natural sweetener that doesn’t impact blood sugar. However, since these are keto bars they are pretty high in fat, but most of the fat content is from heart-healthy fats. With all this considered, we rated the formulation a 3 out of 5. 

These bars were tested by GGR Senior Staff Writer Caine Wilkes, OLY, USAW-L1. He rated the taste a 4.5 out of 5. “It’s very peanut butter forward with chocolate chips and peanut bits. I’m not mad about it, though. It’s pretty good; I’m a fan,” he said. 

Caine also highly approved of the texture, which can be hit or miss with protein bars, rating these a 5 out of 5 in this category. “It kind of melts in your mouth. It literally feels like you’re snacking on peanut butter with chocolate chips,” he shared. 

The price is neither too high nor too low, which is why we rated it a 3 out of 5. Each bar costs approximately $3.33. Caine shared, “A little pricey, but a very good tasting bar, with a higher protein content than other keto bars. No added sugars or sugar alcohols either. I would, and currently am snacking on this.”

Best Dairy-Free Protein Bar for Diabetics: Bulletproof Protein Crisp Bars

Good for: Those with a milk allergy or lactose intolerance looking for a protein bar that’s easy on the stomach 

Best Dairy-Free

Bulletproof Protein Crisp Bar

GGR Score: 3.7

Check Price

Product Highlights

• Gluten-free, dairy-free, and keto-friendly
• Each bar delivers 11 g of pea protein, 1 g of sugar, and 4 g of net carbs
• Available flavors include: Salted caramel, peanut butter chocolate chip, coconut chocolate chip, chocolate mint chip
• Peanuts and peanut butter are sourced and tested to meet EU compliance for toxins

Pros & Cons

Pros

• Convenient
• Several flavor options
• Only 1 g of sugar
• Gluten- and dairy-free

Cons

• Not everyone like the taste of the pea protein
• Stevia and monk fruit may cause stomach issues for some

Bottom Line

Available in four flavors, the Bulletproof Protein Crisp Bars provide 11 grams of protein in a low-carb and convenient treat.

Many protein bars use whey or casein protein, which come from cow’s milk. However, there are plenty of dairy-free options available for those who prefer to avoid dairy, such as Bulletproof Protein Crisp Bars. These are a good option for those with a milk allergy or lactose intolerance.

Bulletproof Protein Crisp bars provide 11 grams of protein primarily from pea protein. This plant-based protein contains all nine essential amino acids, important for building and repairing muscles. “Just 11 grams of protein is a bummer; I would love to see that protein content be higher,” said GGR Director of Content Kate Meier, NASM-CPT, USAW-L1, CF-L1.

The protein content isn’t the highest, but we appreciate the 9 to 10 grams of fiber (depending on flavor) in each bar. Fiber not only helps regulate blood sugar but also keeps you feeling fuller for longer, reducing the likelihood of overeating, which can cause blood glucose spikes. 

These bars contain no added sugar, but they do include sugar alcohols, which can cause gastrointestinal discomfort in some people. They’re also sweetened with stevia and monk fruit extracts, both natural, calorie-free sweeteners that won’t raise blood sugar levels. Overall, we rated the formulation a 3.5 out of 5. 

As for taste, Kate rated these a 4 out of 5, and said, “It tastes like a “healthy” peanut butter bar. The flavors are there, but not fully there, like you’d get in something loaded with fat and sugar.” She’d gladly eat them again! Likewise, she also rated solubility a 4 out 5. “For a bar advertised as ‘crisp,’ this is a little chewy, but in a good way. It’s just definitely not crunchy.” 

Kate’s competitive weightlifting team tried these, and the feedback was overwhelmingly positive. No one reported any issues with digestion or discomfort, which isn’t too surprising considering these are dairy-free.

Best Budget Protein Bar for Diabetics: Onnit Protein Bites

Onnit Protein Bites

GGR Score: 4.2

Product Highlights

• Ingredients from 60 plants 
• Whey protein from grass-fed cows 
• 7-9 g of protein, depending on flavor

Pros & Cons

Pros

• Nutrients from 60 plants
• Subscribe and save 15%
• Also sold individually so you can try flavors

Cons

• Contains the allergens soy, tree nuts, milk, and sesame
• Very mixed reviews on the new formula
• Users say chocolate coating melts easily and gets messy

Bottom Line

Onnit Protein Bites have 7 to 9 grams of protein from grass-fed cows and contain nutrients from more than 60 plants. However, the new formula is very divisive with some users loving it and some hating it.

If you’re looking for a quick, affordable protein snack, then Onnit Protein Bites might be just what you’re looking for. These mini bars are made with milk protein and whey protein, complete protein sources providing all nine essential amino acids. 

Each bar offers 7 to 9 grams of protein depending on the flavor. This isn’t a ton, but these are smaller than your standard protein bar. “I would view this like a ‘healthy dessert’ option for when chocolate cravings kick in—or you just want something sweet,” said GGR Director of Content Kate Meier, NASM-CPT, USAW-L1, CF-L1.

RELATED: Protein Snack Ideas

They contain 12 to 14 grams of carbs per serving, with 6 to 7 of those coming from fiber. Fiber can help regulate blood sugar levels, reduce cholesterol, and promote bowel regularity.

However, we don’t love that these include added sugar. While added sugar isn’t ideal for managing diabetes, the presence of fiber, protein, and fat helps to slow the digestion and absorption of sugar, reducing its impact on blood sugar levels. Taking the lower protein content and added sugar into account, we rated the formulation a 2.5 out of 5. 

Kate and members of her weightlifting team (Endless Strength Barbell) tried several flavors and rated them all a 5 out of 5. “Delicious. All flavors are really good. At least half a dozen people tried these bars out, and everyone gave them top marks. Overwhelmingly, we love the taste of these,” shared Kate. 

The texture was another slam dunk, earning a rating of 5 out of 5. “The Coconut Cashew bar is super similar to a Mounds Bar in texture. These are chewy and moist and just…*chef’s kiss*,” said Kate.

As if the taste and texture alone wasn’t enough reason to try these protein bars, they’re also extremely affordable. Each Onnit Protein Bites bar costs $1.67, and we rated it a 4.5 out of 5 for price.

• No added sugar 
• Created in 2016 in Sweden as a healthy alternative to snacks and desserts which mimic a candy bar texture 
• Plant-based flavors: Salty peanut, hazelnut nougat

Pros & Cons

Pros

• Well-reviewed taste
• Variety of flavors
• Plant-based options
• Candy bar–like texture

Cons

• Relatively expensive
• Contains sucralose

Bottom Line

Barebells Protein Bars are one of the few protein bars on the market that effectively mimic the texture of a candy bar, delivering a high-protein and low-to-no sugar snack alternative.

If you like to eat protein bars several times a week, you need to find the best-tasting protein bar that won’t wreck your blood sugar. Our tester loved the taste of Barebells Protein Bars, which come in thirteen unique flavors. 

GGR Senior Editor Erin Chancer, CNC, CPT, rated the taste a 4.8 out of 5. “These protein bars are delicious. They have no added sugar and use sucralose but don’t have that strong artificial sweetener aftertaste. My favorite of the four flavors I tried is the Caramel Cashew; I had to keep checking the label to make sure I wasn’t actually eating a candy bar,” she said.

RELATED: Best-Tasting Protein Bars

They’re also sweetened with maltitol, a sugar alcohol that has a lower impact on blood sugar levels than regular sugar. However, it can still cause a moderate rise in blood sugar and may lead to gas or bloating in some individuals.

“The texture has a mixture of crunch and a soft nougat-like filling. I really enjoyed it,” shared Erin, who rated the texture a 4.5 out of 5. Depending on the flavor you choose, some have a soft texture and others pack some crunch.

These bars are high in protein compared to many others, offering 20 grams of milk protein and collagen protein. They offer a delicious way to boost protein intake, which aids in regulating blood sugar levels¹. Milk protein is great for muscle recovery and repair after workouts, while collagen supports bone, joint, and skin health.

These bars aren’t as high in fiber as some others on our list. They also have a slightly higher net carb content, with 18 to 20 grams of carbs and only 3 grams of fiber per bar. All in all, we rated the formulation a 4 out of 5. 

Best Protein Bar for Diabetics for Weight Loss: Low Carb Think! Keto Bars

Best for Weight Loss

Low Carb think! Keto Bars

GGR Score: 3.9

Check Price

Product Highlights

• Keto-certified by the Paleo Foundation 
• 10 g protein, 4 g net carbs
• Available in four flavors
• Non-GMO and kosher ingredients

Pros & Cons

Pros

• Taste is popular
• Keto-friendly
• Kosher and non-GMO
• No artificial colors or flavors

Cons

• High fat content
• Contains stevia
• May melt in transit

Bottom Line

The Low Carb think! Keto Bars are available in four popular flavors and make for a great on-the-go snack for those following a keto diet.

The keto diet is popular among people with diabetes who are trying to lose weight and reduce their carb intake. Low Carb Think! Keto Bars are extremely low in net carbs, the type of carbohydrates that can raise blood sugar levels. This makes them a great fit for a keto diet, which promotes fat metabolism for energy instead of relying on carbs, boosting fat burning and supporting weight loss.

These bars offer 14 grams of total carbs, but 10 of those are from fiber and sugar alcohols. This results in only 4 net carbs per serving, which would likely only have minimal effects on blood sugar. Sugar alcohols, such as erythritol found in this product, are low-calorie sweeteners that don’t significantly impact blood sugar levels but may cause gas and bloating for some. 

Each bar provides 10 grams of protein from whey protein isolate. Whey protein is rich in leucine, a branched-chain amino acid that stimulates muscle protein synthesis, promoting muscle growth. Building and maintaining muscle can help boost your metabolism, which is beneficial during weight loss. Considering the low net carbs, sugar alcohols, and lower protein content, we rated the formulation a 2 out of 5.

GGR Senior Staff Writer Caine Wilkes, OLY, USAW-L1, liked these bars but was slightly disappointed by the amount of protein. “A pretty good tasting bar, more for keto than protein, though,” he said. He enjoyed the flavor, rating these a 4 out of 5 for taste, and shared, “The chocolate and peanut butter really come through. Very surprised that I didn’t notice any stevia or other sweetener flavor.”

Texture rated highly as well at a 4 out of 5. “The inside of the bar is a little dry, but with the chocolate coating and crunch from the peanut bits inside, I actually enjoyed the texture overall,” said Caine.

Product Highlights

• Refrigerated plant-based protein bars sweetened with monk fruit

• 10 flavors include peanut butter and jelly cookie dough, strawberry cheesecake dough, chocolate chip cookie dough, peanut butter chocolate chip cookie dough, white chocolate macadamia cookie dough, double dark chocolate cookie dough, chocolate coconut, snickerdoodle, caramel peanut butter chocolate chip, and mint double dark chocolate chip

Pros & Cons

Pros

• Texture of cookie dough
• No sugar alcohols
• No artificial ingredients
• Convenient option

Cons

• Many do not like the newest recipe of these bars
• Inconsistent taste of bars depending on batch received

Bottom Line

If you are a fan of cookie dough and looking for a bar that is both keto-friendly and able to satisfy that sweet craving, the BHU Foods Refrigerated Protein Bars may be for you.

BHU Keto Bars are USDA Organic certified, gluten-free, and contain no sugar alcohols. They may be a good option for those looking for more wholesome, clean ingredients that won’t cause uncomfortable digestive symptoms.

Depending on the flavor, these provide 7 to 13 grams of protein per bar from plant-based ingredients like organic cashews and organic pea protein. They are incredibly high in fiber, with each bar boasting 9 to 12 grams. According to the Centers for Disease Control and Prevention², fiber can help with diabetes control because it doesn’t cause a spike in blood sugar the same way other carbohydrates do. 

BHU Keto Bars are sweetened with monk fruit extract, a natural sweetener. They contain only 1 gram of sugar per bar. We love the low sugar, natural sweeteners, and fiber content, but wish they had more protein. We rated the formulation a 3 out of 5.

To keep their form, these need to be kept chilled. “A great bar, but it’s inconvenient since you have to keep them refrigerated. You can tell your fingers start to warm the bar up as you’re eating them,” said GGR Senior Staff Writer Lauren Strong, CPT. 

Lauren enjoyed the taste, rating this category a perfect 5 out of 5. “Flavor on the label was actually how the bar tasted, with a creamy texture. The bars taste like dessert without being too sweet,” she shared. According to Lauren, “The bar has a nice, soft, doughy texture. It’s almost buttery to bite into!” She also rated texture a solid 5 out of 5.

Product Highlights

• 17-21 grams of protein depending on the flavor
• Low net carbs

Pros & Cons

Pros

• Great product to keep your macronutrients on target
• Simple, grab-and-go snack
• Gluten-free helps with dietary restrictions
• Low in sugar
• Very filling

Cons

• Chewy texture isn’t for everyone
• Uses sugar alcohols, which can upset digestion
• The company recently changed the formula a bit and several customers didn’t like the change
• Can get too soft if gets too hot (like in a car or gym bag)

Bottom Line

Quest Nutrition has been serving the health and protein market since 2010 and they continue to give people high-quality products. They offer some unique flavors in their bars not seen by competitors such as White Chocolate Raspberry, Chocolate Sprinkled Donut, and Lemon Cake.This is one of the few bars that is actually recommended to stick in the microwave for about 15 seconds to produce a rich, tasty treat. Using a high-quality dairy-based protein, Quest Bars are dense and chewy in texture.These bars fall pretty well right in the middle as far as price point so you don’t have to break the bank to get your protein in consistently. You will want to pay attention to the ingredients as many of the customers who have used Quest for a long time were not fans of the newer formula, although if you don’t have anything to compare it to, you might find you like it just fine.

Quest Nutrition Protein Bars have held up over time, staying a popular choice for many thanks to their high protein content. Each bar packs 20 to 21 grams of a combination of milk protein and whey protein, which is impressive for a protein bar without the chalky taste often associated with high-protein bars. 

Research³ indicates that a high protein diet may help stimulate insulin production, the hormone that moves sugar from the blood into cells. High-protein bars like Quest Nutrition Protein Bars may help regulate blood sugar levels in people with diabetes whose bodies don’t produce enough insulin. 

RELATED: Best Protein Bars for Muscle Gain

We love the fiber content of Quest bars, ranging from 13 to 17 grams depending on the flavor. The prebiotic fiber in these bars helps nourish beneficial bacteria in the gut for improved immunity and digestion.

GGR product tester Amanda Capritto, CPT, CES, CNC, CF-L1, rated the formulation a 4 out of 5. “Lots of sugar alcohols and other artificial ingredients. I’d rate these higher because the macro profile is great, but I personally wouldn’t call these objectively the healthiest bar,” she said. 

These bars are sweetened with stevia, sucralose, and erythritol. Stevia and erythritol are natural sugar substitutes, while sucralose is an artificial sweetener. All of these sweeteners have a minimal impact on blood sugar. Most flavors contain only 1 gram of sugar per serving.

According to Amanda, “These can certainly cause digestive upset due to the level of erythritol.” She rated side effects a 4 out of 5. Amanda sometimes experiences bloating if she eats the bars on consecutive days.

Regarding taste, we rated these a 4 out of 5. “Quest Bars are one of those things that some people love and some people hate. The artificial taste can be strong, but I’d eat these in a pinch or if they’re around,” shared Amanda. Although she likes the taste, the texture is a bit too dense and chewy, earning this category a 3.5 out of 5. 

Best Crunchy Protein Bar for Diabetics: Power Crunch

Best Crunchy

Power Crunch Protein Bars

GGR Score: 4.3

Check Price

Product Highlights

• Wafer protein bar made with whey protein
• Protein ranging from 12–14 g
• Available in a variety of flavors
• Aimed to satisfy sweet cravings

Pros & Cons

Pros

• No sugar alcohols
• Added vitamins and minerals
• Good dessert replacement if you have a sweet tooth

Cons

• Contain sucralose
• Only 12 g of protein per serving
• Long list of ingredients

Bottom Line

The Power Crunch Protein Bars are a fairly low-calorie, low-sugar protein bar that satisfies a sweet tooth.

If chewy protein bars feel too dense, you might prefer something with a little more crunch. Power Crunch bars have a layered, wafer-like texture that’s light and airy. Despite their lighter feel, they still include 12 to 14 grams of protein, depending on the flavor, which could help stabilize your blood sugar.

Power Crunch bars are made with high DH hydrolyzed whey protein. This means the whey protein has been broken down into tiny particles, making it easier for the body to digest and absorb. 

We rated the formulation a 2.5 out of 5. These bars are low in carbs, with only 11 to 12 grams per serving, but also low in fiber and contain added sugar. Most flavors provide just 1 gram of fiber and include 5 to 8 grams of added sugar. Diabetics need to monitor their added sugar intake to avoid blood sugar spikes. 

GGR Head of Content Nicole Davis, CPT, PN1-NC, has been eating Power Crunch bars for years. She tried all 12 flavors and rated them all a 5 out of 5. “Normally, I’d have one or two favorites, but these are all good enough to have again. They’re a touch sweet so some may not care for them, but I think the taste is a shining quality of this bar,” she shared.

Regarding texture, she said, “They are super crumbly and messy, but it’s a nice change of pace from most other types of chewy, dense protein bars.” Nicole rated the texture a 4 out of 5.

Product Highlights

• Grass-fed jerky bars
• Paleo-friendly
• Whole30-compliant
• Dairy-free
• Gluten-free
• 8-15 g of protein per bar

Pros & Cons

Pros

• Very unique protein bar option
• Great to pack for outdoor hikes and activities or bring on-the-go
• Appeals to many different lifestyles including paleo, Whole30, keto, and dairy-free
• Great flavor combos
• Soft texture (not like regular beef jerky)
• 9 flavor options
• Humane grass-fed beef sources

Cons

• Have a different texture than typical protein bars
• Not suitable for vegetarians or vegans
• Some flavors are kind of greasy

Bottom Line

When you think of protein bars you might consider the word sweet, but savory and spicy probably wouldn’t normally come to mind. EPIC Nutrition is working on changing that up and improving meat-based protein options on the market while also maintaining a high level of respect for the animals and environments that they live in.

EPIC Jerky Bars are different from any other protein on our list because their primary ingredient is meat. Unlike the other sweet, decadent protein bars, these are salty and savory. These all-natural bars are free of gluten, soy, dairy, grains, and refined sugar.

EPIC Jerky Bars provide between 6 and 15 grams of protein depending on the flavor option you choose. They contain 100% animal protein from chicken, bison, pork, venison, and beef. Furthermore, they contain only 1 to 8 grams of carbs, and all but two flavors have zero grams of added sugar, making them a good option for regulating blood sugar. We rated the formulation a 4.5 out of 5. 

According to GGR product tester Amanda Capritto, CPT, CES, CNC, CF-L1, “They keep amazingly well for long day excursions like hikes because they won’t melt. The ingredients are minimal, with the first ingredient being whatever type of meat the bar is made of, followed by flavorings and preservatives like encapsulated lactic acid and salt.”

Amanda highly approves of every EPIC bar she’s tried, rating their taste a 5 out of 5. “My all-time favorite is the bison bacon cranberry, followed closely by chicken sriracha and venison sea salt pepper. The flavors are robust and balanced; all around a good buy for those who eat meat.” 

Again, these aren’t your typical cookie dough chewy bars. Their texture is unique and may not be for everyone. Amanda rated texture a 4 out of 5 and shared, “I don’t mind the texture, but I do think that some people might be put off by it. Each bar is different, depending on how tough or dry the type of meat is naturally.”

Product Highlights

• Made from whole foods
• High fat, moderate protein, and low carb 
• Plant-based fats and protein 
• No added sugar or sugar alcohols 
• Keto certified
• Meets ethical business standards

Pros & Cons

Pros

• All natural
• No added sugar or sugar alcohol
• Keto-friendly
• Plant-based
• Convenient

Cons

• Expensive
• Taste is not for everyone

Bottom Line

Dang bars are high-fat, moderate-protein, and low-sugar snacks sourced from whole foods with fat and protein derived from vegan pea protein, almond butter, cocoa butter, and coconut.

There are plenty of protein bars made with whey or casein, both dairy-based proteins, but finding a high-quality vegan option can be tough. Our tester recommends Dang Bars, which are keto bars made with plant-based protein and 100% vegan ingredients.

RELATED: Best Vegan Protein Powder

These provide 9 grams of pea protein per bar. Pea protein is a complete protein, meaning it contains all the essential amino acids that our bodies cannot produce and must be obtained through food. They’re low in total carbs (11 grams) and high in fiber (6 grams), which can help reduce cholesterol and regulate blood sugar. They’re sweetened naturally with stevia extract. 

GGR Head of Content Nicole Davis, CPT, PN1-NC, rated Dang Bars formulation a 3 out of 5.  “If I was rating this as a keto bar, it’d score higher, but with 9 grams of protein and 15 grams of fat, this isn’t so much of a high protein bar. Still, it’s one of the better plant-based options we’ve tested, especially in terms of flavor,” she said. 

Keto bars can be a good option for people with diabetes due to their low carbohydrate content and minimal added sugars, helping to prevent blood sugar spikes. While these bars are higher in fat, they contain mostly unsaturated fats from nuts and seeds, which can lower inflammation and potentially improve insulin sensitivity. 

Nicole got a variety pack that included the Lemon Matcha, Almond Cookie, and Crazy Rich Chocolate flavors. “The taste of these is good. The Lemon Matcha in particular has a really nice authentic lemon flavor that is unique in a protein bar,” she said. She rated the taste a 4 out of 5. 

“These are pretty dry but not unpalatable. They have some ‘protein crisps’ in them which adds a crunch sort of like a Crunch bar, so extra points for that,” shared Nicole, who rated the texture a 3 out of 5.

Pros & Cons

Pros

• Both crunchy and soft options
• Easy-to-understand list of ingredients
• Relatively affordable
• Convenient option

Cons

• Soft baked bars tasted too dry to some
• Not as sweet as some users would have preferred
• Some found the crunchy variety too hard to chew

Bottom Line

Available in both soft and crunchy options, the Ratio Foods Keto Friendly Bars are a solid snack option for those seeking to keep costs down while following a keto lifestyle.

:ratio KETO Friendly Bars are a crunchy snack made primarily with almonds, pumpkin seeds, and soy protein isolate. These keto-friendly bars are the perfect combination of sweet and salty. “We really enjoyed this one. It pleasantly surprised us. One of the guys compared it to a Nature Valley bar but said he thinks it tastes better,” said GGR Director of Content Kate Meier, who shared these with her weightlifting team. 

These bars are available in three different flavors and offer 11 to 12 grams of plant-based soy protein. Plus, they only contain 9 to 10 grams of carbs and no added sugar, making them more suitable for managing diabetes. These are keto, so they’re high in fat, but most of the fat comes from heart-healthy sources like nuts and seeds. We would have liked the protein content to be higher and therefore rated the formulation a 3 out of 5. 

Kate tried the Toasted Almond bar, which she didn’t think she’d enjoy, but she did. “The Toasted Almond bar has a great cinnamon taste to it. There is a hint of toasted almond, but it’s giving much more cinnamon than anything, and I’m here for it,” she said, rating the taste a 4 out of 5. 

Some nut bars are dry, but not these. “C-R-U-N-C-H-Y. However, it isn’t overly dry, which you might think looking at it. I usually don’t like crunchy bars, but this is one that I would eat,” Kate said. That said, another one of our testers advised staying away from this one if you have dental work. Ultimately, we rated the texture a 4 out of 5.

Bottom Line

Keto Bars are a homemade keto snack comprised of simple ingredients and are packed with a solid amount of fat designed to keep you full for longer.

Keto Bars make grabbing a quick meal on the go easier. They offer 240 calories, 6 grams of protein, and 6 grams of fiber to help you stay full until your next meal. Plus, they’re gluten-free and contain no added sugar. 

The ingredients list on this bar is simple and minimal, featuring natural ingredients that are easy for most consumers to recognize and understand. We rated the formulation a 3 out of 5. The protein is low and we don’t love the aftertaste that comes with sugar alcohols, but we like the natural ingredients. 

The 6 grams of protein comes primarily from almonds, while the 20 grams of fat is from dried coconut, almonds, and coconut oil. These only contain 4 grams of net carbs, which don’t impact blood sugar as rapidly as sugar. 

Although these are higher in calories than most other protein bars on our list, 240 calories isn’t enough to count as a meal on its own. Adding an additional source of carbs alongside protein, like an apple with nut butter or a hard-boiled egg with a whole grain muffin, can help provide more calories while also helping to manage blood sugar.

GGR Director of Content Kate Meier, NASM-CPT, USAW-L1, CF-L1, and members of her weightlifting team, tested all of the Keto Bars flavors and rated them a 4 out of 5 for taste. “There is an aftertaste; it’s almost like you get a little chalky film on your tongue and mouth. You can taste the sugar alcohols at the end for sure,” advised Kate. 

Kate and her team rated the texture a 4 out of 5 and shared, “Definitely a little dry; you might want to have a drink handy! The texture is a little gritty—almost like dirt! But once you taste it, it tastes great.” Overall, they liked the taste and texture of these bars and would have them again.

Other Protein Bars for Diabetics We Researched

We’ve tested numerous protein bars, but not all made it onto our final list. Here are some options we considered but decided not to include in our top picks for diabetics. 

• Atlas Protein Bars: We like that these pack 20 grams of protein per bar, but they are more expensive than other comparable bars at almost $3.00 per serving.
• No Cow Dipped Bars: The 21 grams of plant protein is great, but we just couldn’t get behind the taste of these. 
• CanDo Keto Krisp Bars: The 10 grams of fiber per bar is impressive, but unfortunately, these caused stomach discomfort for our testers.
• Marigold Bars: These were a little too chewy and on the pricier side. That said, the 20+ grams of protein per bar is noteworthy. 

How We Picked and Tested

Our testers include professional athletes, certified nutrition coaches, and personal trainers who know a thing or two about protein bars. We use protein bars ourselves and appreciate their convenience for providing nutrition between meals, after a workout, or while traveling. However, we know firsthand that not all protein bars are created equal, and there are specific considerations to keep in mind for a diabetic diet.

Regarding formulation, we chose protein bars low in total and added sugar as well as net carbs. We prioritized options with more fiber and a reasonable amount of protein. Furthermore, our team narrowed down choices that tasted good, had a pleasant texture, and weren’t too expensive. We intentionally diversified our picks to include a variety of textures, flavors, and protein types. 

Benefits of Protein Bars for Diabetics

Protein bars offer several potential benefits for those with diabetes. Whether you’re looking for a new healthy snack idea or want to lose weight, protein bars could help you reach your goals. 

Blood Sugar Regulation 

Protein bars are a convenient way to boost protein intake, which can support insulin production and help regulate blood sugar absorption. However, not all protein bars are diabetes-friendly, and many are high in other ingredients that could spike blood sugar levels. Choose bars with low net carbs, high fiber, high protein, and no added sugar to maximize their benefits for managing diabetes.

Weight Loss

Weight loss can be especially difficult for those with Type 2 diabetes. Eating more protein, such as through nutrient-dense protein bars, may help boost metabolism and support weight loss when combined with exercise and a balanced diet. Protein also promotes satiety, which can help reduce overeating throughout the day.

Convenience

Maintaining healthy blood sugar levels can feel challenging. Incorporating convenient snacks like protein bars can make sticking to a diabetic-friendly diet easier. While they don’t replace the need for whole-food meals, protein bars offer a quick, worry-free snack option that requires less planning.

Dosing and Interactions 

Protein bars should be consumed as part of an overall diet primarily consisting of whole food meals and snacks. They make a simple snack option but are not generally intended to be meal substitutes as they don’t offer enough calories or nutrients. 

RELATED: Best Diabetic Meal Delivery

Read the labels thoroughly before choosing a protein bar to avoid those with ingredients you may be allergic to. Many snack bars contain common food allergens like dairy, wheat, and nuts. 

Prioritize bars that are high in protein and low in net carbs. Bars with added sugar and higher net carbs can cause quicker spikes in blood sugar levels. Continue to monitor your blood sugar levels as advised by your doctor.

What to Look for in Protein Bars for Diabetics

When it comes to shopping for a protein bar for diabetics it’s important to read the nutrition label and ingredients carefully. Here are a few pointers to help you find the best diabetes-friendly protein bar. 

Protein Content 

Aim for protein bars with 10 to 20 grams of protein. This is generally enough to promote satiety and help regular blood sugar levels. If you’re a vegan or vegetarian, choose plant-based protein bars made with soy or pea protein. For others, opt for protein bars made with whey, casein, or milk protein to promote muscle repair and growth. All of these options are complete protein sources that may help with blood sugar control, metabolism, and muscle building. 

High Fiber

Fiber is another key nutrient that slows the absorption of sugar into the bloodstream. Adequate fiber intake can help reduce blood sugar spikes. Look for products that provide more than 20% of the percent daily value of fiber.

Low or No Added Sugar 

Added sugar can cause blood sugar levels to spike quickly. Natural sweeteners like stevia, monk fruit extract, and sugar alcohols have a much slower impact on blood sugar levels. Look for protein bars with 5% or less of the percent daily value of added sugar, and opt for bars that use natural sweeteners instead.

Low Net Carbs 

Net carbs are calculated by subtracting fiber and sugar alcohols from total carbs. Net carbs represent the types of carbohydrates that have a greater impact on blood sugar levels, primarily sugars and starches. Our list includes several options with fewer than 5 grams of net carbs.
