The 40 Best and Worst Protein Bars

Those protein bars you're eating could be the reason your diet isn't going as planned.

There's no denying it: protein is the name of the game when it comes to health and nutrition these days.

However, even for the most dedicated healthy eaters among us, the idea of toting around grilled chicken and egg whites everywhere we go is even less practical than it is appealing. The alternative for those who want to keep their energy levels high without reaching for the nearest convenience food, comes in the form of protein bars, the ubiquitous health food store staple that promises better health in every bite.

While the convenience of these snacks makes them enticing, what's under the wrapper varies wildly from company to company. Major brands that sit side-by-side on your favorite store's shelves can be like comparing apples and oranges, with one so-called health food relying on artificial sweeteners, high fructose corn syrup, and toxic preservatives to achieve its flavor, while another might be little more than a brick of organic fruit and nuts perfect to enjoy in place of a full meal on a busy day.

So which should you choose? After reading up on the 45 Sources of Protein You Should Be Eating — But Aren't, find out which protein-packed snacks make our list of the 40 Best and Worst Meal Replacement Bars!


Quest White Chocolate Raspberry Protein Bar

Worst: With just 200 calories and 9 grams of fat, Quest's White Chocolate Raspberry Bar seems like it should be able to help you slim down, but not all of its ingredients are as healthy as you might have hoped. Despite the resveratrol-rich red raspberries in this protein bar, it's also packed with sucralose, an artificial sweetener that has been suggested as a culprit for weight gain.

Bariatric Health and Wellness Cinnamon and Raisin Bar

Best: Packing only 150 calories and 7 grams of sugar, this protein bar is relatively light compared to other similar products on the market.

However, if you're susceptible to irritation from soy products, this is one to avoid.


Quaker Protein Baked Bars — Peanut Butter Chocolate

Worst: This bar's oatmeal base may make it seem like a good option, but its health benefits are undeniably dampened by the intense amount of sugar it contains, with 13 grams per bar. This granola bar also contains xanthan gum, an additive that has been shown to increase the water in the intestines of animals by 400%, potentially leading to bloating.

Kellogg's FiberPlus Antioxidants Protein Chewy Bars — Mixed Nut

Worst: This bloat-promoting soy-based bar is doing no favors for your waistline. Not only does it pack a whopping 8 percent of your RDA of sodium, it's also preserved with BHT, consumption of which may increase your risk of stomach cancer, according to a Dutch study.

Zone Perfect Classic Nutrition Bar — Chocolate Coconut Crunch

Worst: Corn syrup, palm oil, sugar, and soy combine for a perfect storm of unhealthy "health" food this so-called nutrition bar.

Nutri Grain Cereal Bars Strawberry

Worst: Don't let this bar's name mislead you — it's anything but full of fresh fruit.

MET-Rx ProteinPlus Protein Bars — Creamy Cookie Crisp

Worst: While just one of these MET-Rx bars provides you with 60 percent of your RDA of protein, at 320 calories, it's also one of the higher-calorie bars out there, and full of less-than-healthy ingredients to boot. With each of these bars, you'll get 20 grams of stomach cramp-causing sugar alcohol, 13 percent of your daily sodium intake, and both sugar and sucralose used as sweaters, doubling your risk of belly fat accumulation.

With 230 calories, 7 grams of protein, and 4 grams of fiber, this bar is filling enough to keep you from grabbing a donut at the office, but not so calorie-packed it will throw your diet off pace. With healthy ingredients, like cholesterol-busting oats, and low-glycemic sweetness like date paste and plum puree, there's little not to like about this protein bar.


18 Rabbits Jr. Organic Granola Bar — Chocolate Cherry

Best: The powerhouse belly fat-fighting duo of cherries and dark chocolate come together in one delicious bar, thanks to 18 Rabbits.

Greens Plus Natural Energy Bar

Best: Gluten-free, non-GMO, and packed with organic ingredients, this brownie-like bar may just be the best thing to happen to pre-packaged meals.

Myoplex Deluxe Bar — Chocolate Peanut Butter

Worst: Chocolate and peanut butter may be one of the all-time greatest flavor combinations, but they're far from their best selves in this high-calorie protein bar.

Health Valley Strawberry Cobbler Multigrain Cereal Bar

Best: Low in calories, sodium, and sugar, this snack bar is packed with organic ingredients proven to melt fat.

Gatorade Whey Protein Bar — Mint Chocolate Crunch

Worst: Corn syrup, sugar, soy, and milk make this protein bar a definite no-go for anyone whose stomach is on the sensitive side. Despite the 20 grams of protein this bar packs, you'll also get 360 calories, making this one to-go meal you'll want to leave at home. To help reduce the effect ingredients like milk and soy can have thought your body, try the 40 Foods That Fight Inflammation!


Atkins Mocha Almond Bar

Worst: Atkins may be the number one name in low-carb products, but low-carb doesn't always mean high-quality nutrition. Ingredients like fiber filler polydextrose, artificial sweetener sucralose, and milk protein all have potentially bloat-inducing effects, so if you want to keep your belly flat, steer clear.

Find out why peanuts (when they're not packed in sugar) should earn a permanent spot on your diet by discovering the 40 Ways Nuts Fight Fat.


Oh Yeah! High Protein Bar — Peanut Butter and Caramel

Worst: Although Oh Yeah! does deliver on its promise of high protein, with more an 27 grams per bar, it's also chock-full of ingredients that could potentially sabotage your path to a Zero Belly. In addition to both sucralose and sugar in the recipe, the Oh Yeah Peanut Butter & Caramel bar also contains maltitol, an artificial sweetener that has been shown to have a laxative effect, according to research published in the European Journal of Clinical Nutrition.


Nature Valley Energy Granola Bars — Cranberry Almond

Worst: A combo of corn syrup and sugar make this bar a treat that's not-so-sweet when it comes to your waistline. While this bar does include some healthy ingredients, like whole grain oats, dried cranberries, and almonds, the 15 grams of sugar you'll get in each bar are hardly worth it.

PowerBar ProteinPlus — Chocolate Brownie

Worst: With both sugar and belly-bloating artificial sweeteners, PowerBar's Chocolate Brownie Bar is one snack you can cross off your list.

Fiber One Protein — Coconut Almond

Worst: Although it's low in calories, with just 140 per bar, Fiber One's Coconut Almond Protein Bar isn't the health food you might have hoped for. Ingredients like soy protein, sugar, palm oil, corn syrup, artificial color, and propylene glycol, which you'll also find in antifreeze, make this a less-than-ideal pre- or post-workout snack. Find out why propylene glycol is such a diet don't by reading up on the 40 Scariest Preservatives and Additives in Your Food!


NuGo Smarte Carb Bar Peanut Butter Crunch

Worst: While you'll find little sugar in this low-carb bar, it's been replaced with artificial sweeteners that can bloat your belly and may even cause you to gain weight.

Best: With a host of healthy ingredients, like oats, peanuts, almonds, flaxseed, pineapple, and papaya, this is one meal replacement bar you can feel good about digging into.
