25 Best & Worst Low-Sugar Protein Bars
By Olivia Tarantino
Using this guide, you’ll be able to maintain lean muscle and curb cravings by munching on one these high-protein, low-sugar bars—without having to count it as a dessert.
If you’re looking to further your better body goals, would you eat a candy bar every day? What about a protein bar? We’re sure the latter sounds more beneficial, but unfortunately, most of the protein bars in the market are loaded with more of the waist-widening sweet stuff than a Snickers. And, because you consider them a health food you can eat every day (rather than a once-in-a-while treat), they can be more likely to hamper your weight-loss or tone-up efforts than help them.
Whether you’re looking for a nutritious, on-the-go option to tide you over between meals or to maintain muscle mass between workouts, low-sugar protein snacks will be game changers—that is, as long as you pick the right one. See which are the best for your belly and which are Not That!s below. And then don’t miss these 29 Best-Ever Proteins for Weight Loss.
Each bar has no more than 13 grams of sugar and no less than 8 grams of protein.
First… The Worst
thinkThin Chocolate Strawberry
Per bar (60 g): 250 calories, 9 g fat (2.5 g saturated fat), 230 mg sodium, 24 g carbs (1 g fiber, 0 g sugar, 12 g sugar alcohol), 20 g protein
Don’t be fooled into thinking you’re getting a deal with this sugar-free bar. To compensate for the lack of sugar, thinkThin loads this bar up with sugar alcohols—12 grams exactly. One of those is maltitol, a low-calorie, plant-based sweetener that studies have found to be associated with stomach and abdominal pain as well as excessive internal gas and flatulence.
Nature Valley Coconut Almond Protein Chewy Bars
Per bar (40 g): 190 calories, 12 g fat (5 g saturated fat), 190 mg sodium, 14 g carbs (5 g fiber, 7 g sugar), 10 g protein
It may look like your favorite GORP (good-old fashioned raisins and peanuts) in a bar, but what you’re really eating when you chomp down on this Nature Valley bar is more fillers than whole foods. It looks like roasted peanuts and coconut, but more of the protein and fat you see in the nutritionals is from soy protein isolate and palm oil than whole foods.
SimplyProtein Maple Pecan
Per bar (40 g): 150 calories, 5 g fat (0.5 g saturated fat), 190 mg sodium, 15 g carbs (7 g fiber, 1 g sugar), 16 g protein
SimplyProtein Apple Cinnamon Whey Bar
Per bar (40 g): 150 calories, 2 g fat (0.5 g saturated fat), 25 mg sodium, 18 g carbs (5 g fiber, 4 g sugar), 15 g protein
These bars may be high in protein, but their ingredient lists read more like supply lists from a chemistry lab than foods from your pantry: protein isolate, vegetable glycerin, calcium carbonate, inulin and xanthan gum. None of the ingredients are harmful for your health, but why miss out on the additional health benefits and micronutrients you get from whole foods for the same amount of protein?
ZONE perfect Nutrition Bar Dark Chocolate Almond
Per bar (45 g): 190 calories, 6 g fat (4 g saturated fat), 200 mg sodium, 22 g carbs (2 g fiber, 13 g sugar), 12 g protein
Don’t be fooled by the name of this bar; the “dark chocolate” is less of what you'd picture in an 85 percent dark chocolate bar and more sugar, alkalized cocoa powder (which renders all antioxidants useless), milk powder and fractionated palm kernel oil (instead of healthy-fat-rich cocoa butter).
QuestBar Protein Bar Cookies & Cream Flavor
Per bar (60 g): 190 calories, 9 g fat (2.5 g saturated fat), 210 mg sodium, 20 g carbs (14 g fiber, 0 g sugar, 2 g erythritol), 21 g protein
Don’t believe everything you read. QuestBar describes this bar as being made “with real cookie crumbles and delicious cream,” but according to the ingredients, the only place that cream could be lurking is in “natural flavors.” Not to mention, the bar may be sugar free, but it's made with a laundry list of additives and chemicals, including artificial sweetener sucralose, and the only whole food is almonds.
Pure Protein Chocolate Peanut Butter
1 bar (50 g): 190 calories, 6 g fat (3.5 g saturated fat), 180 mg sodium, 17 g carbs (<1 g fiber, 2 g sugar, 8 g sugar alcohol), 20 g protein
Is 20 grams of protein worth having to eat fractionated palm kernel oil, artificial sweeteners, disodium phosphate, natural flavors, and laxative-like sugar alcohols? We think not.
PowerBar ProteinPlus Reduced Sugar Lemon Poppy Seed
Per bar (60 g): 200 calories, 7 g fat (2.5 g saturated fat), 130 mg sodium, 25 g carbs (5 g fiber, 3 g sugar, 17 g sugar alcohols), 20 g protein
Unlike the bars below, those seven grams of fat and saturated fat in this bar don’t come as much from nuts as they do from palm kernel oil and canola oil.
And Now… The Best
KIND STRONG & Kind Honey Smoked BBQ
Per bar (45 g): 230 calories, 16 g fat (1.5 g saturated fat), 125 mg sodium, 15 g carbs (3 g fiber, 6 g sugar), 10 g protein
Time to throw away the chips. The first ingredient in this Honey Smoked BBQ bar is considered the best nut for weight loss. Not only are almonds rich in the amino acid L-arginine, which helps build lean muscle and reduces belly fat, but they also contain the minerals riboflavin, magnesium, and manganese, which are essential for a healthy metabolism.

EPIC Bar Bacon
Per bar (43 g): 130 calories, 8 g fat (3 g saturated fat), 330 mg sodium, 0 g carbs (0 g fiber, 0 g sugar), 15 g protein

Soul Sprout Sweet 'N Salty Sprouted Nut Bar
Per bar (43 g): 220 calories, 15 g fat (2 g saturated fat), 200 mg sodium, 15 g carbs (3 g fiber, 10 g sugar), 8 g protein
Sprouting is a process that increases the bioavailability of certain active micronutrients in protein, making them more accessible for your body to use as energy. This bar harnesses that natural process by sprouting almonds and cashews. You can read more about it in our exclusive guide: Why Sprouted Foods Enjoy a Place in Your Diet.

exo Bar Cocoa Nut
Per bar (60 g): 300 calories, 20 g fat (4.5 g saturated fat), 45 mg sodium, 23 g carbs (7 g fiber, 13 g sugar), 10 g protein
It might remind you of Fear Factor, but eating insects is the next big thing. And did we mention that they pack a nutritional wallop? Crickets have about as much protein as chicken breast but with three times the calcium. And in this bar, they provide nearly all the protein, aside from some almonds.
$30.81 for 12-pack ($2.56 each) at Amazon.com
thinkThin Protein Nut Bar, Chocolate Coconut Almond
Per bar (40 g): 190 calories, 11 g fat (3.5 g saturated fat), 115 mg sodium, 17 g carbs (3 g fiber, 8 g sugar), 9 g protein

Organic, grass-fed beef isn’t cheap for a reason. Testing shows that when cattle graze on their natural food instead of inflammatory corn, their protein consists of more anti-inflammatory omega-3 fatty acids and conjugated linoleic acids: fats that have been utilized in weight-loss pills.
