Best High-Fiber Protein Bars of 2025

“I started taking medication that suppresses my appetite, so I sometimes forget to eat breakfast. To combat this, I impulsively bought these bars. I remember how my mom enjoyed the Atkins bars back in the early 2000s, and they always tasted good to me. With their high protein and fiber content, I’ve repurchased them at least 7 or 8 times. I eat one daily, and they keep me feeling full. They taste great but not overly indulgent. I highly recommend them!”

“While I haven't found a diet food that’s absolutely amazing, these bars are tasty compared to others. They are a bit on the pricier side, though.”

“I was initially skeptical because most protein bars are typically awful, but these are actually delicious! I buy them frequently and highly recommend them.”

"I always have these on hand. I appreciate the high fiber and protein content. Honestly, I prefer the taste over most protein bars."

"I just got my grab 1 fiber bars. I noticed the nutrition label on the box doesn't match what’s on the actual bar. There’s a difference in calories and protein. I'm curious to hear from the company about this. I did try one, and they taste good."

"It’s tough to find a bar with both high protein and fiber. If you’re looking for both, this is definitely the bar for you. I will buy again."

“I absolutely love the taste of these peanut butter snacks! Plus, they have lots of protein and only 4 grams of sugar! Great product at a reasonable price!”

“I was pleasantly surprised by how good these taste. They are filling and the perfect size. The right mix of sweet and salty. I've tried other bars that were a fail—too chalky and small. These Atkins Peanut Butter Granola Protein Meal Bars are excellent and perfect for when I'm on the go.”

“These are not the typical bars you find at big box stores; they are so much better! They have the perfect amounts of chewy, crunchy, salty, and peanuty flavor. While they may not satisfy a sweet tooth, they are filling and satisfying for hunger cravings. I can’t recommend them enough, even if they are a bit spendy.”

"These Atkins bars are incredibly tasty. I love the texture and size, plus they provide great nutrition and have a reasonable calorie count."

"I find these bars remind me of Baby Ruth candy bars. They have a perfect taste, not overly sweet, just the way I like it."

"These bars are fantastic; they taste like a candy bar. They have become a staple in my diet. I highly recommend trying them!"

“I find the Atkins Chocolate Crème Protein Wafer Crisps absolutely amazing! They taste like a treat, with only 170 calories, 4g net carbs, and 1g of sugar. The combination of the crispy texture and rich chocolate crème filling satisfies my sweet tooth without the guilt. They’re high in fiber, which is a great bonus. I’ll definitely keep these on hand for a quick, delicious, and nutritious dessert! Highly recommend!”

“I really enjoyed the Atkins Caramel Chocolate Peanut Nougat Snack Bars. The combo of caramel, chocolate, and peanut nougat makes for a satisfying flavor that’s perfect for a quick snack or post-workout treat. They’re high in fiber and low in sugar, making them ideal for my keto lifestyle. However, I did notice a slightly odd aftertaste that lingered. It didn’t ruin the experience for me, but it’s worth mentioning if you’re sensitive to flavors.”

“I’m thrilled that the lemon flavor is back! I believe it’s the best among the wafer crisps varieties. While I enjoy the peanut butter and chocolate flavors too, I simply love the lemon the most. They are just so good!”

"This will be my go-to protein bar. The texture is really soft and satisfying, especially compared to other protein bars I've tried. Lots of protein with little sugar is great for me. The flavor is subtle yet enjoyable—just the right balance. And like other reviews mentioned, there's no weird aftertaste, which I've encountered with other vegan protein bars. I'm excited to try the other flavors next!"

"I was thrilled to find this product right before Halloween, as it provided a healthier alternative to sugary chocolate bars! While it’s not identical to a regular candy bar, the chewier texture and lower sweetness are good trade-offs, especially considering the higher protein and lower sugar content. I really enjoyed the caramel flavor and would love to see more unique flavors, like seasonal options!"

"I used to love these bars, especially the s'mores variety. However, I recently tried the new softer recipe and was disappointed. They’re too chewy and stick to the roof of my mouth, making them hard to swallow. The taste is decent, but the texture inside is quite unpleasant. I do appreciate the added crunchy bits, but I miss the old formula. Is there any chance the s'mores flavor will return?"

"I recently tried the Nectis Apple Cinnamon Meal Replacement Bar, and I can confidently say it's a game-changer! It not only satisfied my taste buds but also gave me a fantastic energy boost during my busy meetings. The bar is incredibly convenient for someone like me who often lacks time for meals. The outstanding flavor felt like indulging in a dessert, and it’s low in sugars, which is a huge plus!"

"After a long search, I finally found the right protein bar. Although the price is on the higher side, I truly enjoy the flavor. It’s not as sweet as others I've tried, which I appreciate. The 20g of protein really satisfies me, and it doesn’t upset my stomach despite the fiber content. I just wish it could be a little less sweet to reach perfection!"

"I was initially hesitant about these plant-based meal replacement bars, but now I’m on my second box of the Cinnamon/Apple flavor. They’re packed with nutritious ingredients and keep me feeling full longer than any other bar I've tried. Plus, they taste delicious! I’m looking forward to trying the Berry flavor next."

"I find these bars to be really good. The soft texture and fun flavors are a big plus for me, and the fact that they have no artificial sweeteners and low sugar content while being packed with fiber and protein makes them a healthy choice. They might be a bit on the pricier side for a snack, but I really don’t have much to complain about since they taste great."

"This is my first experience with these bars, and I only tried the donut flavor. I have mixed feelings about it. While the flavor isn't bad, it's quite bland, and if I didn’t know it was supposed to taste like a donut, I wouldn’t have a clue. Some reviews mentioned it tastes like playdough, and I can see that. I’m interested in trying other flavors but might look for them in a store to avoid potential issues with product quality."

"These bars have a strong mint flavor, so if mint isn’t your thing, these might not be for you. Personally, I think they are delicious and avoid that strange aftertaste that some protein bars have. My only minor concern is that I wish they were a bit larger, but they are filling enough to keep me satisfied for a few hours."

"I truly love the taste of these bars, and they keep me full for hours!"

"Unlike many fiber products I've tried, these are not gritty or like cardboard. They have a decent mouth feel and the flavor is quite good."

"I was pleasantly surprised by the chocolaty taste and the absence of a gritty, powdery feel. Out of all the fiber bars I've tested, this one is definitely the best."

"My son and I were in search of new dairy-free protein snacks. These have quickly become my new favorite, and I find myself craving them. They are sweet, but not overly so, and quite filling. I just ordered more of this flavor and another one!"

"As a construction worker, I always need convenient and tasty snacks to keep me going during long days. The No Cow Chocolate Chip Cookie Dough Protein Bars have really impressed me. They taste delicious and are a great change from the usual bland options. With 20 grams of protein and only 1 gram of sugar, they provide a nice energy boost without any crash. They’re also vegan and gluten-free, which is fantastic for dietary restrictions. The only downside is that they’re a bit chewy for my liking, but overall, they're a solid four-star option for anyone needing a quick protein fix!"

"I absolutely love the No Cow High Protein Bars in Chunky Peanut Butter flavor. They satisfy my cravings while providing a substantial 20 grams of plant-based protein. Plus, with only 1 gram of sugar and 4 grams of net carbs, they're perfect for my low-carb diet. The creamy peanut butter taste combined with real peanut chunks is simply irresistible. These bars fit perfectly into my busy lifestyle, and I feel good about the clean ingredients. They’re definitely my go-to snack!"

"I’ve tried many protein bars, but these No Cow bars stand out. They have great nutritional value with high fiber and low fat. Being vegan is a significant plus for me, and they contain 20 grams of protein, which is rare. However, I have noticed that they can sometimes taste a bit cardboardy. But overall, I’m definitely planning to buy them again!"
