Benefits of Protein Bars for Weight Loss
Meal Replacement
Protein bars can be a quick meal when you're busy.
They come in set sizes, so it's easy to know how many calories you're eating.
Many protein bars have a mix of nutrients like a regular meal but with fewer calories.
So you can use them on days when you don't have time to cook or eat a full meal and still be on track with your weight loss journey. [1]
While a protein bar isn't as good as a meal made with different healthy whole foods, it can work well when you're in a hurry or don't have time to prepare a full meal.
Aids in Satiety
Satiety means feeling full after eating. Protein bars help with this because they have a lot of protein, which takes longer to digest than carbs.
Eating more protein actually increases hormones that make you feel full, like GLP-1, peptide YY, and cholecystokinin. [2]
It also lowers the hormone that makes you feel hungry, called ghrelin. [3]
Protein also takes longer to digest than carbohydrates, which means it stays in your stomach longer, keeping you full for a longer time. [4]
If you eat more protein instead of some carbs and fat, you might feel less hungry and more satisfied. This could help you eat fewer calories overall.
This is especially helpful if you are on a caloric deficit diet or doing body recomp.
Increases Protein Intake
Protein is one of the most important nutrients for your body.
According to Dr. Gabrielle Lyon, you should eat around 1.2 to 1.6 grams of protein per kilogram of your body weight. [5]
This sounds easy, but it can be quite difficult.
For example, if you weigh 80 kilograms, you need to eat 96 grams of protein per day.
Even if you manage to eat 30 grams per meal (breakfast, lunch, and dinner), you only reach 90 grams, and eating 30 grams per meal is not easy.
This is where protein bars can help.
A typical protein bar has around 20 grams of protein.
If you have two bars a day, one between breakfast and lunch and another between lunch and dinner, you get an extra 40 grams of protein.
This makes it easier to reach your daily protein goal through your regular meals.
Buying Guide: What to Look for in Protein Bars for Weight Loss
Protein Amount
When choosing a protein bar for weight loss, check how much protein it contains.
Look for bars with at least 10 grams of protein per serving.
A high protein intake can help you build lean muscle while you're losing weight.
Some bars offer up to 20 grams of protein. Choosing the ones that fit your diet is helpful.
For example, if your diet already has a lot of protein, you might be ok to choose a bar with lesser protein like 10 g.
The type of protein matters too. Whey, casein, and soy are complete proteins that contain all essential amino acids.
Plant-based proteins like pea or rice protein can also be good options, especially when combined.
However, it's important to keep in mind that plant proteins and animal-derived proteins differ in their amino acid profiles, which can affect their overall effectiveness.
So carefully consider your dietary needs and preferences when choosing the protein source.
Calorie Content
Pay attention to the number of calories in each protein bar.
For weight loss, you want a bar that's filling but not too high in calories.
Look for bars with around 200 calories.
This range can provide enough energy and nutrients without adding too many calories to your daily intake.
There are also protein bars with very low calories (under 150). However, the problem with these low-calorie bars is that they might not be very filling as a snack.
Remember to factor in the bar's calories as part of your total daily calorie goal.
Some bars might be marketed as low-calorie but contain artificial sweeteners or fillers to make up for taste, so always check the ingredient list.
Balance is key – a slightly higher calorie bar with more protein and fiber might keep you fuller longer than a very low-calorie option.
Presence of Sugar Alcohol
Check if the protein bar contains sugar alcohols.
These are sweeteners that have fewer calories than regular sugar.
They're often used in low-calorie or sugar-free foods.
They are added to reduce the calorie and sugar content of protein bars.
The problem with these sugar alcohols is that they can be tricky for our bodies to handle, especially if we eat a lot of them quickly.
These sweeteners, while useful for some people, can potentially cause digestive issues. [6]
Common sugar alcohols include sorbitol, maltitol, and erythritol.
They're often listed separately from sugars on nutrition labels.
So, to avoid potential gastric issues, it is recommended to opt for protein bars with the lowest amount of sugar alcohols.
Studies show that limiting your sugar alcohol intake to 10 grams a day is a safe amount. [7]
How We Picked the Best Protein Bars for Weight Loss
Protein Content
We chose protein bars with high-quality protein sources with at least 10 grams of protein per serving.
We wanted bars to help with weight loss by keeping you full and adding to your daily protein intake.
Whether you are going to the gym or doing home workouts, you need to maintain an adequate protein intake.
We also checked for good protein sources, like whey, casein, soy, and pea protein.
These provide all the essential amino acids your body needs.
Fiber Content
We also looked at how much fiber each bar had, which is important for weight loss because it makes you feel full for a longer time.
This can stop you from eating too much and improve your overall gut health.
Fiber is a type of carbohydrate that your body can't digest. It comes in two forms: soluble and insoluble.
Soluble fiber dissolves in water and can help lower cholesterol and blood sugar levels.
Insoluble fiber adds bulk to your stool and helps food move through your digestive system.
Both types are important for weight loss and overall health. We looked for bars with at least 3 grams of fiber per serving.
But be careful not to eat too many protein bars for your fiber. The type of fiber in these bars can upset your stomach in large enough amounts.
To increase your fiber, we suggest fruits and vegetables.
Adherence to Diet Restrictions and Preferences
We know that people have different dietary needs and preferences. So, we included protein bars that fit various diets.
We looked for options that were gluten-free, dairy-free, vegan, and keto-friendly.
We checked the ingredient lists carefully to make sure the bars matched their claims.
And most importantly, we picked these based on taste, texture, previous experience, and overall eating experience because who wants to eat something that tastes horrible?
With that being said, here are our picks for the best protein bars for weight loss.
Top 10 Protein Bars for Weight Loss
Pure Protein Bars - Best Overall Protein Bar for Weight Loss
I’ll be honest: this bar is NOT the best tasting. But measuring between nutritional content, protein, taste, price, and for the specific goal of weight loss? This bar takes the cake.
These bars mix healthy fats with various chocolate flavors, making them feel indulgent even though they're low in sugar. It is pretty chewy, and the base is hard when you bite into it, so it may take some time to finish the bar.
I like that this bar is budget-friendly, at only about $1.40 per bar, which is close to what you'd pay for a scoop of most whey protein powders. You can also regularly find them in bulk at Costco.
They're tasty enough to satisfy cravings, gluten-free, under 200 calories, and the saturated fat is on the lower end of the spectrum.
Protein is higher than carbs, which is rare.
So if you want to lose weight with no diet constraints, care little about taste, yet want a budget-friendly meal replacement option, then this bar is it.

Flavors: Birthday Cake, Chewy Chocolate Chip, Chocolate Deluxe, Chocolate Peanut Butter, Cookies & Cream, Lemon Cake, and more

Perfect Bar: Most Filling Protein Bar for Weight Loss
These bars are unique, as they’re the only ones on this list that require refrigeration.
It combines freshly ground nut butter with organic honey and over 20 organic superfoods, making them both nutritious and tasty.
They are slightly pricier, at about $2.49 per bar, but the quality ingredients make it worth it and it’s really filling. So is a viable full meal replacement.
Each bar provides 17 grams of whole-food protein, making it an ideal option for a quick energy boost as well.
The bar tastes great. It’s soft but has a slightly chalky texture. The flavor is solid, especially if you like peanut butter.
The only downside is that it is higher in sugar content than other bars and difficult to take with you on the go, because it does require refrigeration.
Summary for Perfect Bar
Calories Per Serving: 330-340

Bulletproof Protein Bar - Best Low-Carb Protein Bar for Weight Loss
Each of these Bulletproof bars has 11 grams of protein and only 4g of carbs.
While the protein is not a huge amount, it's still enough to give you a protein boost that can help curb those annoying between-meal cravings.
And with only 4 grams of carbs, you don’t have to worry about your blood sugar spiking and then crashing.
However, it is on the pricey side, costing up to $2.40 per bar and hard to find in stores. We got ours online through Amazon.
The bar was not my favorite. Taste like a peanut butter cardboard. There's texture was nice though, soft and dry.
But for such a low amount of carbs, very worth it if your goal is to minimize carb.
There are a few additives, like gums and glycerin, which don't contribute much nutritionally.
So, if you are sensitive to these, you might want to pick another option.
Summary for BulletProof
Calories Per Serving: 150
Flavors: Peanut Butter Chocolate Chip, Coconut Chocolate Chip, Salted Caramel, Chocolate Mint Chip
Main Source of Protein: Pea Protein
Protein Per Serving: 11 g
Price: $2.40
Pros
11 grams of protein
Low in sugar (1 gram per bar)
Gluten-free and dairy-free
Variety of flavors
Contains fiber (9-10 grams per bar)
Cons
Lower protein content compared to some other bars
Hard to find in most grocery stores
Texture is a bit chewy and dry
Contains artificial sweeteners
think! Bars - Best Low-Sugar Protein Bar for Weight Loss
think! Bars are perfect if you are on a low-sugar diet.
My favorite flavor, the Chocolate Crème Cupcake, tastes like a real cupcake, isn’t gritty, and has no aftertaste.
It’s gluten-free, the texture is good and soft, the cholesterol level is low, and overall a solid protein bar.
On the flip side, it does have 7g of erythritol per bar, which should be ok for most people, but if your tummy isn't able to handle that, you might want to skip this one.
It also has higher calories and higher fat from saturated fat. Despite the low sugar, the net carbs are high and would not be my go-to during low-carb cycles.
The protein content is also low compared to other brands. Lower than 19% of total calories and less than carbs.
Total sugar is very low at only 1g, but the sugar alcohol content is up there at 12g.
Summary for think! Protein
Calories Per Serving: 180-220
Flavors: Creamy Peanut Butter, Brownie Crunch, Chunky Peanut Butter, Lemon Delight, Chocolate Fudge, Double Caramel Bliss, Cookies and Creme, Berries & Creme, Coconut Cake, White Chocolate, Maple French Toast
Main Source of Protein: Milk Protein Isolate, Whey Protein Isolate
Protein Per Serving: 10g
Price per bar: $1.80
Pros:
• Gluten-free
• No artificial sweeteners
• Low in sugar (1g per bar)
• Tasty flavors that mimic desserts
• Convenient for on-the-go snacking
• Good source of healthy fats (14g per bar)
Cons:
• It could be too sweet for some
• Lower in protein compared to other protein bars
• Relatively high in calories for the protein content
• Contains sugar alcohols, which can cause digestive issues for some people
RXBar - Best High-Fiber Protein Bar for Weight Loss
RXBars are for you if you want a protein bar made from whole foods without artificial ingredients.
It tastes almost homemade, has no graininess or aftertaste, and even feels healthy. I like how the packaging states the ingredients of each bar, and the protein comes mostly from egg whites.
The only downside is the protein-to-calorie ratio.
Go for this one if you value ingredient transparency and don't mind paying more for quality.
Summary for RXBar
Calories Per Serving: 200-220 (varies by flavor)
Flavors: Chocolate Sea Salt, Peanut Butter, Blueberry, Coconut Chocolate, Maple Sea Salt, Mixed Berry, Peanut Butter Chocolate, and more
Main Source of Protein: Egg Whites
Protein Per Serving: 10g - 12g
Price per bar: $2.35
Pros:
• Made with simple, whole-food ingredients
• No artificial sweeteners or added sugars
• Good source of protein and fiber
• Many flavors to choose from
• Gluten-free and dairy-free
• Transparent labeling
Cons:
• Higher in calories compared to some protein bars
• Contains dates, which are high in natural sugars
• Some flavors can be tough or sticky to chew
• Relatively expensive
Dang Bar - Best Keto Protein Bar for Weight Loss
Dang Bars are our top pick for Keto, for its low carb and low sugar content. It’s also good if you are vegan, vegetarian, or need to eat plant-based foods for long-term health goals.
There’s no grainy aftertaste and the texture feels rich and hearty yet is not as sweet as some other bars. The almond flavor is strong so if you’re a fan of almond,, this could be the best bar for your.
The downside is that the protein content is lower compared to other brands we’ve tried. If this is a concern, then go with a higher protein brand.
Summary for Dang Bar
Calories Per Serving: 210
Flavors: Almond Cookie, Crazy Rich Chocolate, Peanut Butter, Toasted Coconut, Lemon Matcha, Cardamom Chai, Saigon Cinnamon Chocolate
Main Source of Protein: Almond Protein, Pea Protein
Protein Per Serving: 7g - 9g
Price per bar: $3.39
Pros:
• Keto-friendly with only 5g net carbs
• High in healthy fats (15g per bar)
• Vegan
• Made with ethically sourced ingredients
• No artificial sweeteners
• Unique, Asian-inspired flavors
Cons:
• Lower in protein compared to some protein bars
• Relatively high in calories
• More expensive than some other bars
Fit Crunch Best-Tasting Protein Bar for Weight Loss
Fit Crunch bars are our top pick for taste and a good choice as a snack after a workout or during a busy day.
The taste is decent but the crunchy texture is what makes it better. The bar is soft and not stale tasting. And there’s no grainy aftertaste.
Protein is higher than carbs at 16g. And this is probably the closest thing to a real chocolate bar on the list.
The only negative is the sugar alcohol content is relatively high, and the calories are also up there, but that’s the trade-off for better taste, right?
Summary for Fit Crunch
Calories Per Serving: 190
Flavors: Chocolate Peanut Butter, Peanut Butter & Jelly, Chocolate Chip Cookie Dough, Chocolate Brownie, Chocolate Coconut Almond, Cinnamon Twist, Milk & Cookies, Lemon Cake, Apple Pie, Caramel Peanut, Mint Chocolate Chip, Strawberry Strudel
Main Source of Protein: Milk Protein Isolate, Whey Protein Isolate
Protein Per Serving: 16g
Price per bar: $2.06 - $2.25
Pros:
• High protein content
• Great taste and texture compared to many protein bars
• Baked, giving a softer, more enjoyable eating experience
• Good variety of flavors
• Available in different sizes for various needs
Cons:
• Higher in sugar alcohols than some protein bars
• Contains artificial sweeteners
• Not suitable for those with dairy allergies
• Some flavors are high in saturated fat
No Cow Dipped Bar - Best Dairy-Free Protein Bar for Weight Loss
No Cow-Dipped Bars are another great choice for all you plant-based eaters out there.
It’s soft, and the chocolate flavor is deep. The Chocolate Sea Salted Caramel (My favorite) has coarse salt grain on top, which adds a nice touch that isn’t in most protein bars.
It’s a bit chalky but goes down well, and there isn’t much of an aftertaste to me, at least. Some of our other coaches did not agree.
We like the 15 grams of protein per bar plus the 10 grams of fiber and low sugar.
This is exactly what we want in a protein bar because the goal isn’t just to get a good amount of protein but also to curb your hunger.
The downsides are the price, which is on the higher side, and the presence of sugar alcohols, which not everyone’s stomach can handle well.
Summary for No Cow
Calories Per Serving: 200-220
Flavors: Chocolate Sea Salt, Chocolate Salted Caramel, Chocolate Peanut Butter Cup, Chocolate Mint Cookie, Chocolate Sprinkled Donut, Chocolate Coconut Almond, Strawberry Shortcake, Birthday Cake, Sticky Cinnamon Roll, Key Lime Pie, Frosted Gingerbread Cookie
Main Sources of Protein: Brown Rice Protein, Pea Protein
Protein Per Serving: 15g
Price per bar: $2.75
Pros:
• Gluten-free
• Dairy-free and vegan
• Low in sugar (5g per bar)
• Good fiber content (10g per bar)
• High protein content (15g per bar)
Cons:
• It could be dry or chalky to some
• More expensive than some other protein bars
• Mixed reviews on aftertaste due to plant proteins
• Uses sugar alcohols, which can cause digestive issues for some people
Orgain, Plant-Based Protein Bar - Best Organic Protein Bar for Weightloss
Orgain protein bars were created by Dr. Andrew Abraham, a cancer survivor who struggled to find nutritious, convenient foods during his treatment.
These bars are specifically targeted for vegans, people with food sensitivities, or anyone looking for a cleaner protein bar option.
However, if you're looking for a very high protein content or a more dessert-like taste, these might not be the best fit.
If vegan had a taste, this would be it. These bars were chewy and soft, with a slight crunch. The flavor is very light, not too sweet at all with a nutty aftertaste that's not very strong.
Orgain bars are best suited for you if you value organic ingredients and are willing to trade some protein content for cleaner, less processed nutrition.
Summary for Orgain Protein
Calories Per Serving: 150
Flavors: Chocolate Coconut, Peanut Butter Chocolate Chunk, S'mores, Chocolate Chip Cookie Dough.
Main Source of Protein: Organic Pea Protein, Organic Brown Rice Protein
Protein Per Serving: 10g
Price per bar: $2.00
Pros:
• Made with organic ingredients
• Plant-based and vegan
• No artificial flavors, colors, or preservatives
• Gluten-free and soy-free
• Lower in calories compared to many protein bars
• Good source of fiber (6g per bar)
Cons:
• Lower protein content compared to some other bars
• Some users find the texture dry or chalky
• Contains added sugars (5-6g per bar)
• Some flavors may not taste as indulgent as non-organic options
ALOHA Bar - Best Plant-Based Protein Bar for Weight Loss
ALOHA Plant-Based Protein Bars were born out of a desire to create a truly clean, plant-based protein bar.
It's perfect for you if you're on a plant-based diet or want to switch to one and you want to make sure you're getting enough protein.
It has a texture almost like a thicker carrot cake and is chewier than most of the bars on this list. The aftertaste is minimal, and the overall taste is not bad.
Overall a solid bar, but not my personal favorite.
Summary for Aloha
Calories Per Serving: 240-250
Flavors: Blueberry, Chocolate Chip Cookie Dough, Coconut Chocolate Almond, Chocolate Mint, Chocolate Fudge Brownie, Peanut Butter Chocolate Chip, Vanilla Almond Crunch, Maple Sea Salt, Peppermint White Chocolate, Chocolate Caramel Pecan, Oatmeal Chocolate Chip, Pumpkin Spice, Lemon Cashew.

Price per bar: $2.67
Pros:
• Suitable for various diets (vegan, paleo, keto)
• Made with organic, plant-based ingredients
• No artificial flavors, colors, or preservatives
• Relatively high in fiber (10g per bar)
• Good balance of macronutrients
• Non-GMO and gluten-free
Cons:
• Moderate protein content compared to some competitors

The best options are high in protein and fiber, which help you feel full while being low in calories and sugar.
These bars are useful for quick meals or snacks when you're busy but still want to stick to your diet.
Always check the nutrition facts and ingredients before buying to make sure they fit your goals.
Lastly, keep in mind that while protein bars can be a helpful tool in your weight loss diet, they shouldn't replace all your regular meals.
Instead, combine them with a balanced diet and regular exercise for the best results.

Perfect Bar: Most Filling Protein Bar for Weight Loss

It combines freshly ground nut butter with organic honey and over 20 organic superfoods, making them both nutritious and tasty.
They are slightly pricier, at about $2.49 per bar, but the quality ingredients make it worth it and it’s really filling. So is a viable full meal replacement.
Each bar provides 17 grams of whole-food protein, making it an ideal option for a quick energy boost as well.
The bar tastes great. It’s soft but has a slightly chalky texture. The flavor is solid, especially if you like peanut butter.
The only downside is that it is higher in sugar content than other bars and difficult to take with you on the go, because it does require refrigeration.

Bulletproof Protein Bar - Best Low-Carb Protein Bar for Weight Loss
Each of these Bulletproof bars has 11 grams of protein and only 4g of carbs.
While the protein is not a huge amount, it's still enough to give you a protein boost that can help curb those annoying between-meal cravings.
And with only 4 grams of carbs, you don’t have to worry about your blood sugar spiking and then crashing.
However, it is on the pricey side, costing up to $2.40 per bar and hard to find in stores. We got ours online through Amazon.
The bar was not my favorite. Taste like a peanut butter cardboard. There's texture was nice though, soft and dry.
But for such a low amount of carbs, very worth it if your goal is to minimize carb.
There are a few additives, like gums and glycerin, which don't contribute much nutritionally.
So, if you are sensitive to these, you might want to pick another option.

Flavors: Peanut Butter Chocolate Chip, Coconut Chocolate Chip, Salted Caramel, Chocolate Mint Chip

Protein Per Serving: 11 g

think! Bars - Best Low-Sugar Protein Bar for Weight Loss
think! Bars are perfect if you are on a low-sugar diet.
My favorite flavor, the Chocolate Crème Cupcake, tastes like a real cupcake, isn’t gritty, and has no aftertaste.
It’s gluten-free, the texture is good and soft, the cholesterol level is low, and overall a solid protein bar.
On the flip side, it does have 7g of erythritol per bar, which should be ok for most people, but if your tummy isn't able to handle that, you might want to skip this one.
It also has higher calories and higher fat from saturated fat. Despite the low sugar, the net carbs are high and would not be my go-to during low-carb cycles.
The protein content is also low compared to other brands. Lower than 19% of total calories and less than carbs.
Total sugar is very low at only 1g, but the sugar alcohol content is up there at 12g.

RXBar - Best High-Fiber Protein Bar for Weight Loss
RXBars are for you if you want a protein bar made from whole foods without artificial ingredients.
It tastes almost homemade, has no graininess or aftertaste, and even feels healthy. I like how the packaging states the ingredients of each bar, and the protein comes mostly from egg whites.
The only downside is the protein-to-calorie ratio.
Go for this one if you value ingredient transparency and don't mind paying more for quality.
Summary for RXBar
Calories Per Serving: 200-220 (varies by flavor)
Flavors: Chocolate Sea Salt, Peanut Butter, Blueberry, Coconut Chocolate, Maple Sea Salt, Mixed Berry, Peanut Butter Chocolate, and more

There’s no grainy aftertaste and the texture feels rich and hearty yet is not as sweet as some other bars. The almond flavor is strong so if you’re a fan of almond,, this could be the best bar for your.
The downside is that the protein content is lower compared to other brands we’ve tried. If this is a concern, then go with a higher protein brand.
Summary for Dang Bar

Fit Crunch Best-Tasting Protein Bar for Weight Loss
Fit Crunch bars are our top pick for taste and a good choice as a snack after a workout or during a busy day.
The taste is decent but the crunchy texture is what makes it better. The bar is soft and not stale tasting. And there’s no grainy aftertaste.
Protein is higher than carbs at 16g. And this is probably the closest thing to a real chocolate bar on the list.
The only negative is the sugar alcohol content is relatively high, and the calories are also up there, but that’s the trade-off for better taste, right?
Summary for Fit Crunch
Calories Per Serving: 190
Flavors: Chocolate Peanut Butter, Peanut Butter & Jelly, Chocolate Chip Cookie Dough, Chocolate Brownie, Chocolate Coconut Almond, Cinnamon Twist, Milk & Cookies, Lemon Cake, Apple Pie, Caramel Peanut, Mint Chocolate Chip, Strawberry Strudel

• High protein content
• Great taste and texture compared to many protein bars
• Baked, giving a softer, more enjoyable eating experience
• Good variety of flavors
• Available in different sizes for various needs
Cons:
• Higher in sugar alcohols than some protein bars
• Contains artificial sweeteners

• Some flavors are high in saturated fat
No Cow Dipped Bar - Best Dairy-Free Protein Bar for Weight Loss
No Cow-Dipped Bars are another great choice for all you plant-based eaters out there.
It’s soft, and the chocolate flavor is deep. The Chocolate Sea Salted Caramel (My favorite) has coarse salt grain on top, which adds a nice touch that isn’t in most protein bars.
It’s a bit chalky but goes down well, and there isn’t much of an aftertaste to me, at least. Some of our other coaches did not agree.
We like the 15 grams of protein per bar plus the 10 grams of fiber and low sugar.
This is exactly what we want in a protein bar because the goal isn’t just to get a good amount of protein but also to curb your hunger.
The downsides are the price, which is on the higher side, and the presence of sugar alcohols, which not everyone’s stomach can handle well.
Summary for No Cow
Calories Per Serving: 200-220
Flavors: Chocolate Sea Salt, Chocolate Salted Caramel, Chocolate Peanut Butter Cup, Chocolate Mint Cookie, Chocolate Sprinkled Donut, Chocolate Coconut Almond, Strawberry Shortcake, Birthday Cake, Sticky Cinnamon Roll, Key Lime Pie, Frosted Gingerbread Cookie

Orgain, Plant-Based Protein Bar - Best Organic Protein Bar for Weightloss
Orgain protein bars were created by Dr. Andrew Abraham, a cancer survivor who struggled to find nutritious, convenient foods during his treatment.
These bars are specifically targeted for vegans, people with food sensitivities, or anyone looking for a cleaner protein bar option.
However, if you're looking for a very high protein content or a more dessert-like taste, these might not be the best fit.
If vegan had a taste, this would be it. These bars were chewy and soft, with a slight crunch. The flavor is very light, not too sweet at all with a nutty aftertaste that's not very strong.
Orgain bars are best suited for you if you value organic ingredients and are willing to trade some protein content for cleaner, less processed nutrition.

ALOHA Bar - Best Plant-Based Protein Bar for Weight Loss
ALOHA Plant-Based Protein Bars were born out of a desire to create a truly clean, plant-based protein bar.
It's perfect for you if you're on a plant-based diet or want to switch to one and you want to make sure you're getting enough protein.
It has a texture almost like a thicker carrot cake and is chewier than most of the bars on this list. The aftertaste is minimal, and the overall taste is not bad.
Overall a solid bar, but not my personal favorite.
